The utilization of the Internet and wireless communication reaches its pinnacle from one side of the planet to the other. Marking the rise of criminal activity in recent years sees enormous growth in security breaches and data theft-related cases in mobile phones. To mitigate them, the implementation of security patches, safety fixes, and updates in mobile devices is of high priority for the organization. The need to foster techniques and procedures in the field to be able to extract and precisely dissect digital crime cases, providing valuable tactical data about the investigation. Mobile forensics is a developing branch assisting the investigator in criminal trials and investigations. Acquisition, Collection, and Analysis of mobile phones settle the purpose of recovering cumulative and corroborative evidence. Upgradation and innovation of mobile devices with time imposed a challenge to mobile forensic technology to extract information from such devices. The study aims at extracting comparative and statistical approaches in the analysis of Physical data acquisition utilizing significant versatile mobile criminological proprietary tools. The proposed study also introduces newly developed utility tools along with their characteristic features which help in successful data extraction from mobile devices.

Trying to understand the causes of climate change can be confusing. On the one hand, methane (CH4) emissions from cattle, and methane emissions from food wastes in landfills, are said to contribute to greenhouse gases (GHGs) that drive climate change.  People are working on feed additives for dairy cows to reduce their methane emissions. But, at the same time, cattle manure and food wastes can be fed into anaerobic digesters to convert these organic wastes to biogas; the resulting “renewable methane” or “renewable natural gas” (RNG), can be used in place of fossil natural gas and avoid extra GHG emissions and stop global warming. Can we have it both ways?  Burning gasoline in our cars and trucks generates carbon dioxide (CO2), which is said to contribute to climate change. But more than 8 billion people on planet Earth, breathe in oxygen and exhale carbon dioxide every minute of the day. And so do all the other animals who live on this planet, breathe in oxygen and exhale carbon dioxide. Is our breathing also contributing to climate change, just as the emissions from our automobile tailpipes?It is time to step back from all the hype, evaluate the various sources of CO2 and CH4 being generated and review the “mass balance” of these gases in our atmosphere. Some of these are part of the natural biogenic carbon cycle and some are simply adding to the overall mass balance. What is driving climate change - excess GHGs from the biogenic carbon cycle, excess emissions from other sources, or both? Let’s take a fresh look at the available data.  (Of course, water vapor also plays a part in the climate change story, as a “positive feedback” effect. As non-condensable GHGs rise in concentration and slightly warm the planet, slightly warming oceans add a bit more water vapor to the story and push the warming up a bit more).  During the past few decades, a great deal of pertinent data has been carefully observed and recorded, by world-class scientists and engineers. This data is available in the public domain and is now easily available on the internet. These data sources come from reputable organizations, such as NASA (National Atmospheric and Space Administration), NOAA (National Oceanic and Atmospheric Administration), USGS (United States Geological Survey) and international organizations such as the “Global Carbon Project” and “Our-World-in-Data”.  How much of the growing concentration of CO2 (and CH4) in our atmosphere can be attributed to out-of-control emissions of biogenic carbon? How much of the CO2 rise can be attributed to fossil fuel emissions: 10%, 50%, 90%, or more?  The available data appear to show that the emissions from burning fossil fuels, more than account for all of the rise of carbon dioxide in our atmosphere during the past 60 years, or longer.  In comparison, the biogenic carbon cycle data seem to be very consistent, year after year, decade after decade and have little or no impact on climate change. But, let’s have a closer look at the available data, and let the data speak for itself.

Natural products are becoming increasingly important as an unlimited source for obtaining chemical substances with possible pharmacological potential. Current existing drugs for the treatment of cutaneous leishmaniosis produce major side effects; therefore the search for new drugs is justified. The stem bark of Zanthoxylum chiloperone var. Angustifolium Engl. (Rutaceae) is traditionally used in Paraguay for its antiparasitic properties. The leaf extract was evaluated for the first time to determine its leishmanicidal activity in BALB/c mice infected with amastigote forms of Leishmania amazonensis (PH8). The mice were treated orally with the extract at three concentrations (100, 50 and 10 mg/mL), intralesional (50 mg/mL), and subcutaneously using glucantime as a control (100 mg/mL). The percentage of decrease in parasite load was measured and with intralesional 50 mg/kg a reduction of 72% occurred, with the reference drug (Glucantime) a reduction of 62% was obtained with the same oral dose a reduction of 50%, while with an oral dose of 10 mg/mL the percentage of reduction was 55%. When the oral dose was increased to 100 mg/mL, the reduction percentage of the parasitic load was only 16%. These results indicated that the leaf extract of Z. chiloperone var. angustifolium Engl. at low oral concentrations (50 and 10 mg/mL) had very good activity against L. amazonensis, and it was even more efficacious intralesionally at 50 mg/mL but at the oral dose of 100 mg/kg has very reduced antiparasitic activity. This study showed the efficacy of the extract leaves of Z. chiloperone in reducing the parasite load in an in vivo test, so its use as a potential leishmanicidal could be suggested to develop and evaluate new drugs for the oral treatment of leishmaniosis disease with fewer side effects and lower cost.

Subacute sclerosing panencephalitis is a rare, slow, and insidious neurodegenerative disease caused by measles. This disease mostly has a classic course. However, sometimes it can be presented with atypical manifestations. In this paper, we aim to present a six years old male patient that was hospitalized due to seizures and ataxia. Cerebral magnetic resonance imaging was normal on the first day of admission, but within a few days, the patient started to be apathetic. On the seventh day, magnetic resonance imaging showed hyperintense lesions in the thalamic, brainstem, and periventricular areas. Periodic epileptiform discharges were detected in the repeated electroencephalogram. Investigations from the cerebrospinal fluid showed markedly elevated measles virus IgG at 230U/ml consistent with the diagnosis of SSPE which should always be ruled out when a patient comes in with uncontrollable seizures, ataxia and apathy.

Background: Having claimed lives, HIV/AIDS is still a significant global public health concern. Antiretroviral therapy (ART) is now widely available, and this rapid expansion of access is dramatically improving HIV epidemic survival rates worldwide.Objectives: The aim of this study was to identify the mortality risk factors and survival status of ART patients attending Hawassa Comprehensive Specialized Hospital in 2020.Methods: In a five-year retrospective cohort research, all patients seen between January 2015 and December 2019 were analyzed. The data were analyzed with SPSS 25.0. The Kaplan-Meier Log-rank model was employed to gauge the survival time of ART patients based on explanatory variables. Both bivariate and multivariate Cox proportional hazards regression models were employed to identify the independent causes of mortality.Results: Patients on ART had a 74% overall survival probability. With a median survival of 34 months, there are 0.135 deaths for every 100 person-years. Hemoglobin level (HR = 2.38; 95% CI = 3.3-6.3), WHO clinical stage III and IV (HR = 3; 95% CI = 2.2-9.5, p = 0.04), Age >=60 (HR = 1.6; 95% CI = 1.3-2, p = 0.04) and Functional status bed ridden (HR = 3.1; 95% CI = 1.2-9.4,p = 0.04) were all independent predictors of death among RVI patients.Conclusion: In comparison to trials conducted in wealthy countries, the survival rate of ART patients in this study was low. Patients who are anemic; WHO advanced clinical stage; old age, and functional status bedridden should be closely followed and monitored.

Approximately 73.4% of global deaths are caused by chronic non-communicable diseases, among them, cardiovascular and cerebrovascular diseases, tumors, and chronic respiratory diseases ranked in the top 3 respectively [1]. An accumulating body of evidence showed that the risk of all-cause mortality in cancer patients with cardiovascular disease (CVD) was 3.78 times higher than that of those without CVD and 8.8% of cancer survivors died of CVD [2]. Heart failure (HF) is a serious manifestation or terminal stage of various heart diseases. Although myocardial damage and dysfunction are the main causes of HF, the cardiovascular injury caused by the tumor itself and the detrimental effect of cancer treatment also play an important role. More recently, the data has suggested that up to 25% - 30% of patients with HF have histories of cancer for about 10 years; and cancer also determines the prognosis of heart HF [3]. 

Specific quantification of therapeutic tissue stem cells (TSCs) is a major challenge. We recently described a computational simulation method for accurate and specific counting of TSCs. The method quantifies TSCs based on their unique asymmetric cell kinetics, which is rate-limiting for TSCs’ production of transiently-amplifying lineage-committed cells and terminally arrested cells during serial cell culture. Because of this basis, the new method is called kinetic stem cell (KSC) counting. Here, we report further validations of the specificity and clinical utility of KSC counting. First, we demonstrate its quantification of the expected increase in the hematopoietic stem cell (HSC) fraction of CD34+-selected preparations of human-mobilized peripheral blood cells, an approved treatment product routinely used for HSC transplantation therapies. Previously, we also used the KSC counting technology to define new mathematical algorithms with the potential for rapid determination of TSC-specific fractions without the need for serial culture. A second important HSC transplantation treatment, CD34+-selected umbilical cord blood (UCB) cells, was used to investigate this prediction. We show that, with an input of only simple population doubling time (PDT) data, the KSC counting-derived “Rabbit algorithms” can be used to rapidly determine the specific HSC fraction of CD34+-selected UCB cell preparations with a high degree of statistical confidence. The algorithms define the stem cell fraction half-life (SCFHL), a new parameter that projects stem cell numbers during expansion culture. These findings further validate KSC counting’s potential to meet the long-standing unmet need for a method to determine stem cell-specific dosage in stem cell medicine.

Percutaneous coronary angioplasty is a minimally invasive procedure aimed at unclogging a coronary artery with a low complication rate (with a serious complication rate of 3% to 7% and a mortality rate of 1.2%). Device entrapment during PCI is a rare but life-threatening complication that occurs in < 1% of PCIs and balloon entrapment comes second after coronary guidewires. We present the case of 68-years-old man, smoker, hypertensive and type2 diabetic that presents angina with evidence of ischemia on myocardial tomoscintigraphy and in whom the radial coronary angiography reveals a tight calcified mid LAD stenosis. During his PCI and after dilatation with an NC balloon 2.5 × 12 the latter refuses to deflate and remains trapped in the lesion with the appearance of pain and ST-elevation despite several attempts to dilute the product in the inflator and to burst it by overexpansion. Traction on the balloon resulted in the deep intubation of the guiding-catheter, which comes in contact with the trapped balloon, and the rupture of the latter’s hypotube, which remains inflated at the site of the lesion and mounted on the 0.014 guidewire. We put a second 0.014 guidewire distally in the LAD and twisted with the distal part of the first guidewire, then we introduced a second balloon 2.0 × 20 over the second guidewire until the distal part of the guiding-catheter and inflated to trap the stucked balloon. We gradually removed this emergency assembly that allowed us to retrieve the trapped balloon. The control injection revealed a thrombotic occlusion of the LAD treated by thrombectomy and anti-GPIIbIIIa followed by a DES 2.75 × 28 placement. The patient was discharged 48 hours later with a good LVEF. The possible balloon entrapment mechanisms are an acute recoil of a highly calcified lesion with compression of the incompletely deflated balloon, which seems to be the case in our patient, strangulation of the proximal balloon end by the guiding-catheter if the balloon is removed before complete deflation and break or bend of the hypotube. The solutions in case of undeflatable balloon entrapment are to dilute the product in the inflator, to burst it by overexpansion, to pierce it through a stiff guidewire (or through its other end on a Microcatheter or OTW balloon), to cut its outer part and let it empty passively, to introduce a second guide-wire and perform a Buddy-Balloon or to transfer the patient to Surgery. Material entrapment remains a rare but life-threatening complication, its eviction requires the choice of material size and gentle manipulations (small balloons in the event of a calcified lesion) and its management uses different techniques, the choice of which depends on the clinical and anatomical situation. 

Introduction: Sonographic scan tests are real-time procedures but the female reproductive systems are subject to continued changes beyond the mid-menstrual period. Therefore a second test may be useful after mid-menstrual ultrasound tests among women with infertility who first had normal ultrasound tests during the mid-menstrual period. Aim: The aim of this study is to find out whether physiological changes beyond the mid-menstrual period in the female reproductive system could develop into findings that could be missed at the first ultrasound test among women with infertility during mid menstrual period. Method: One hundred and forty (140) women participated in this study, over a period of 12 months. The inter-observer correlations were carried out. The ultrasound test measured the diameters of the endometrium and ovarian follicle. The study was carried out during the mid-menstrual cycle when normal changes are optimal. The subjects were women of childbearing age (18 years - 40 years) with 28 days cycles who were referred from the fertility clinic. Women who had previous pelvic surgery, women on fertility therapy, and women who were unsure of the date were excluded from the study. Only women who met the inclusion criteria were selected for the study. The selection was by convenience sampling method. The women underwent the first phase of the ultrasound test during the mid-menstrual cycle. Those who had ultrasonographic-positive infertility reports were returned to the referral clinic. Only women who had normal ultrasonographic fertility reports were included in the second phase of further ultrasonographic tests. The scans were carried out further for four days for this second phase study and the result was again compared with normal values. (Endometrium Normal range 7.4 mm - 13.5 mm and ovarian follicles normal range 17.4 mm to 23.5 mm). Results: The first phase of the scan showed 108 (77%) of the women had positive infertility results for endometrium and ovarian follicles, while 32 (23%) of the women had a normal ultrasonographic result and were rescanned over days. The findings of the second phase scan showed that 10 subjects (7.30%) showed new abnormalities, Findings were distributed in three sub-groups in this second phase of the study. Sub-group A, 4 (2.67%) had enlarged unruptured follicles, sub-group B, 6 (4.30%) had an endometrial cavity filled with fluid, sub-group C, 22 (15.70%) subjects still had normal scans who may be referred for other studies. Conclusion: Women with infertility who had a normal scan at the mid-menstrual cycle should be followed up with a second-phase ultrasound scan before other tests.

Aim: To evaluate the hemodynamic changes and side effects during endotracheal intubation with Macintosh laryngoscope and intubating laryngeal mask airway.Materials and methods: A prospective, simple randomized, comparative study on 100 patients 18 years - 60 years of age, divided into two groups: Group A comprising intubation with Macintosh laryngoscope and Group B intubation through ILMA.Results: Total intubation time (in seconds) of group A was 24.38 + 3.26 seconds and of the group, B was 42.94 + 1.24 seconds. At 2,4 and 6, a higher rise in mean heart rate was noted in group A (p < 0.05). At 2,4,6 and 8 minutes difference in mean SBP and mean DBP of the two groups was statistically significant with a p - value of < 0.05 with a significant increase of mean SBP and mean DBP in patients of group A. The difference for all complications was not significant between the two groups.Conclusion: Intubation via intubating laryngeal mask airway can be done as an alternative to direct laryngoscopy using a Macintosh blade as intubation via intubating laryngeal mask airway has shown to have lesser hemodynamic changes.

Azotobacter was selectively isolated and purified from the soil samples of Xinjiang Salt Lake Scenic spot, the fermentation technology of exopolysaccharides (EPS) by Azotobacter was optimized, and the antioxidant activity of exopolysaccharides (EPS) was studied. The bacteria were isolated and purified from the soil samples by the scribing method and the 16SrRNA gene was used for molecular identification. The carbon source, fermentation time, inoculation amount and pH of target bacteria in the exopolysaccharides (EPS) fermentation process were optimized through single-factor experiments and their antioxidant activity was measured. Eight types of Azotobacter were isolated and purified from the soil samples of Salt Lake scenic spot. Among them, As101, which showed 99.58% homology with Azotobacter salinestris, was selected as the target strain. Through single-factor experiments which used exopolysaccharides (EPS) yield and exopolysaccharides content as indexes, the optimal conditions for the As101 fermentation process were determined as follows: fermentation temperature 35, fermentation time 96h, pH 7 and mannitol as carbon source. Exopolysaccharides content from Azotobacter salinestris  was 61.35% and the yield was 6.34 g/L. The results of the exopolysaccharides (EPS) antioxidant activity experiment under optimal conditions showed that As101 EPS had excellent scavenging ability against DPPH free radical, ABTS free radical and hydroxyl free radical, with IC50 values of 6.11 mg/ml, 2.42 mg/ml and 9.57 mg/ml, respectively. As101 with high yield and high exopolysaccharides content was isolated from saline soil in a special environment of Xinjiang, and the EPS obtained showed excellent antioxidant activity. The Azotobacter found in this study would provide the material basis for further opening up the adsorption of exopolysaccharides on heavy metals and the improvement of saline-alkali soil and contribute to further understanding of the structure and other activities of exopolysaccharides derived from Azotobacter.

The stem rot disease has emerged globally as a major threat to oilseed Brassica's productivity and seed quality. The generalist causal pathogen Sclerotinia sclerotiorum (Lib.) de Bary shows large variability in their aggressiveness and pathogenicity. Revealing the pathogen's metabolic profile and signaling components in host-pathogen interaction is fundamental in understanding host resistance to the disease. In this study, the metabolites released by the pathogenic strains of S. sclerotiorum under the axenic culture have been identified using the untargeted high-resolution UPLC-QTOF-ESI-MS/MS. The analysis of the ethyl acetate extracts of the S. sclerotiorum culture revealed ten major secondary metabolites namely, sclerin, sclerotinin-B, sclerone, melanin, bostrycoidin, botcinin-D, botcinin-A, gliovirin, scleramide, and botcinic acid. The later six metabolites are being reported for the first time in the culture extract of the S. sclerotiorum pathogen. Based on the overlapping and unique informative peaks in the chromatograms, the six S. sclerotiorum strains were grouped into three major clades in the phylogenetic analysis. The clustering based on metabolic profiles does not substantiate the diversity based on morphology or virulence differences over the host. The findings of the study signified the metabolites secreted under the axenic conditions are varies based on their growth and developmental stages and may not necessarily be the determining factors for their differential aggressiveness and virulence to their host. 

Background: Liver Transplantation (LT) is the definitive treatment for Autoimmune Hepatitis (AIH) in patients with decompensated cirrhosis, liver failure and hepatocellular carcinoma. Outcomes of LT in AIH among black-Africans are not well-defined. We performed a single-center retrospective-review of adult LT patients. The study period was from 1st August 2004-31st August 2019. The primary aim was to document 1- & 5- year patient and graft survival. A secondary aim was to compare the survival of black-Africans to Caucasians. Data was analyzed using survival-analysis. Results: A total of 56 LT were performed for AIH. Sixty-seven percent (n = 38/56) had confirmed AIH on explant histology. Of these, the majority i.e., 79% (30/38) were female and 21% (8/38) were male. There were equal numbers of black-African 42% (n = 16/38) and Caucasian 42% (n = 16/38) patients. Rejection was four-times higher in black-Africans as compared to Caucasians. Forty-four percent (n = 17/38) had an acute rejection episode and 13% (5/38) had chronic rejection. Recurrence was found in four black-African females. Post-LT patient survival at 1- and 5- years was 86.5% and 80.7%, and graft survival was 94% and 70.8% respectively. The 5- year patient survival was insignificantly lower for black-Africans (73.9%) as compared to Caucasians (83.7%) (p - value 0.26, CI 6.3 - 12.2). Five-year graft survival was significantly lower among black-Africans (55%) as compared to Caucasians (84.8%) (p - value 0.003 CI 3.8 - 8.1)Conclusion: Black-Africans had a four-fold higher rate of rejection compared to Caucasians. Recurrent AIH was only found in patients of black ethnicity. Similar 1- & 5- year patient survival rates were observed between the two ethnicities. The 5-year graft survival among black-Africans was significantly lower than Caucasians.

Aim: The current paper presents a subjective symptom survey regarding postpartum discomfort (Study 1) and a case study on postpartum care using the program developed based on the survey results (Study 2). Thereafter, health care during the postpartum period is discussed.Methods: Study 1 analyzed 1638 postpartum women who completed the Subjective Fatigue Symptom Scale (SFSS) over the period from June 2012 to December 2019. Study 2 detailed the case of a 33-year-old primiparous woman who answered questions regarding the rehabilitation care program.Results: The 1638 subjects included in Study 1 had a mean age of 32.4 ± 8.2 years and a mean postpartum duration of 4.3 ± 2.3 months. Subjective symptoms included lower back pain, shoulder stiffness, sleepiness, wanting to lie down, yawing, and eye strain. The case included in Study 2 showed certain psychological and physical changes following the exercise program. The results of Study 1 showed that motor system discomfort, such as stiff shoulders and lower back pain, occurred in women across all postpartum stages. Our results demonstrated that care and exercise geared toward improving motor system function are imperative after childbirth. Meanwhile, the results of Study 2 imply that our rehabilitation program based on postpartum physical conditions had positive psychological and physical effects.Conclusion: Taken together, our results suggest that continuing rehabilitative care based on the physical condition during each postpartum stage facilitates improvement in mothers’ physical and psychological discomfort.

Introduction: Percutaneous kidney biopsy is a necessary tool to diagnose many kidney diseases. However, major complications were reported in adults, including bleeding in the kidney or around it, creation of arteriovenous fistula, wound infection, damage to adjacent organs, or even loss of the kidney. Such complications can rapidly develop serious consequences. Exploring risk factors might help in preventing them.Objective: The current study aims to evaluate and explore the complications that happened after percutaneous kidney biopsy in children and associated risk factors.Methodology: A retrospective record-based study was conducted by reviewing the medical records of children with post-ultrasound-guided percutaneous kidney biopsy complications at King Saud Medical City, a tertiary hospital in Riyadh, Saudi Arabia during the period from May 2014 to June 2021. Data were extracted using pre-structured data collection sheet. Data collected included children’s age, gender, primary disease, laboratory findings, and kidney complications with needed management. Results: The study identified 76 children who had undergone 86 ultrasound-guided percutaneous kidney biopsies in the study period and fulfil the inclusion criteria. Children’s ages ranged from 1 years to 15 years with a mean age of 7.3 ± 4.0 years old. Most of the study children had nephrotic syndrome (61.6%; 53), followed by glomerulonephritis (25.6%; 22). Thirty-five (40.7%) children developed at least one of the complications. The most-reported complication was microscopic haematuria (32.6%; 28), followed by gross haematuria (3.5%; 3), Flank pain was reported among 3 (3.5%) children also and hematoma (1 child), only 2 children (3.9%) among those who had no complications recorded Haemoglobin drop > 2 g/dl compared to 3 of those who had complications with no statistical significance (p = .365). Prothrombin time was significantly higher among children who had renal complications than others who had not (11.7 ± 1.8 vs. 10.8 ± 1.2 seconds; p = .022).Conclusion: Suggestive by the low need to intervene in complications, ultrasound-guided percutaneous kidney biopsy is a relatively safe procedure in children. Even in the most commonly observed complication, i.e. hemorrhagic ones, blood transfusion is rarely needed.

Polychlorinated dibenzo-p-dioxins, dibenzofurans and dioxin-like polychlorinated biphenyls are persistent organic pollutants (POPs), which in recent years received huge attention due to their extreme stability, high potential toxicity and bioaccumulation in food chains. The main source of human exposure to these compounds is discovered in foods of animal origin, especially foods rich in fat. The target of the present study was to set up an analytical method for the determination of PCDDs/PCDFs and DL-PCB in vegetable oils, sunflower meals, sunflower seeds, rapeseeds and milk powder. The first step consisted of a semi-automatic Soxhlet extraction for 3 hours, by using a mixture of Hexane: Acetone – 80:20, followed by acid digestion with 55% acid silica and filtration. After concentration, the extract is purified on a multilayer column (silica gel, silica-KOH, silica-H2SO4 anhydrous Na2SO4) followed by an alumina column separation in two fractions (first fraction containing PCDDs/PCDFs and second containing only PCBs). The purified extract was then analyzed by GC/MS/MS. The newly developed approach in our lab was capable to reduce the overall time of sample preparation to seven hours/ per sample. Since the method shows good mean recoveries for all labeled congeners spiked in the samples (for PCDDs/PCDFs – 80% - 110%, for DL-PCBs – 70% - 85%), we assumed the absence of overestimation or underestimation in the analyzed samples.

A highly focused and highly cost-effective failure-oriented-accelerated-testing (FOAT) suggested about a decade ago as an experimental basis of the novel probabilistic design for reliability (PDfR) concept is intended to be carried out at the design stage of a new electronic packaging technology and when high operational reliability (like the one required, e.g., for aerospace, military, or long-haul communication applications) is a must. On the other hand, burn-in-testing (BIT) that is routinely conducted at the manufacturing stage of almost every IC product is also of a FOAT type: it is aimed at eliminating the infant mortality portion (IMP) of the bathtub curve (BTC) by getting rid of the low reliability “freaks” prior to shipping the “healthy” products, i.e., those that survived BIT, to the customer(s). When FOAT is conducted, a physically meaningful constitutive equation, such as the multi-parametric Boltzmann-Arrhenius-Zhurkov (BAZ) model, should be employed to predict, from the FOAT data, the probability of failure and the corresponding useful lifetime of the product in the field, and, from the BIT data, as has been recently demonstrated, - the adequate level and duration of the applied stressors, as well as the (low, of course) activation energies of the “freaks”. Both types of FOAT are addressed in this review using analytical (“mathematical”) predictive modeling. The general concepts are illustrated by numerical examples. It is concluded that predictive modeling should always be conducted prior to and during the actual testing and that analytical modeling should always complement computer simulations. Future work should be focused on the experimental verification of the obtained findings and recommendations.

In this article, we made a research on the subject of Time and Growth. In the life, the Growth is seen as the increase of mass which operates during a certain period. In physics, it is the same. By the Growth, a physical body gets its density increased. The goal of this article is to calculate or predict the energy and force that a physical system can have at its total Growth. To study the Growth, we have defined some equations which help to evaluate the Growth internal force and energy. By the same way, we have also discovered that all physical systems in the Universe are connected by the same interaction. This interaction leads to the loss of density or mass. The Time is the consequence of its manifestation. For studying the effect of this interaction, we have calculated the density of the Universe. We found that the density of the Universe is equal to the density of a photon. In other words, the Universe is a huge photon. That means, like a photon, the Universe does not know the Time. It also means that the Universe is eternal. Its Expansion (not its growth) is due by the fact that, at the moment small systems inside to it grow, the Universe maintains its density constant like a photon. Do not confuse Growth and Expansion. The Growth is the increase of the density; and the Expansion is the increase of the volume without the change of density. The Universe does not know the Growth, it knows the Expansion. All these conclusions are detailed in the development of this article.

A growing number of synthetic plastics derived from fossil fuels are produced, and improper plastic waste management has caused a lot of pollution problems. There are many microplastics in the environment, and they disintegrate slowly in soil and water. The properties of microplastics (MPs) include long residence times, high stability, high fragmentation potential, and the ability to adsorb other contaminants. Invertebrates and planktonic organisms are easily able to accumulate microplastics in aquatic species. Therefore, microplastics (MPs) must be removed from the water and other media. This paper aims to review the occurrence, raw polymers and additives, and remediation methods for removing microplastics from the environment. Several methods are available for removing contaminants, including sorption, filtration and chemical treatments. Various removal methods are discussed along with their methods, efficiency and advantages.

The main focus of this study concentrates on evaluating the quality of groundwater in and around the zone of pattamadai where the production of the mat in this region is a landmark industry, which is using dyes in a larger volume. The primary work starts with the collection of water samples from 13 boreholes and 13 hand-dug wells in different time intervals in the month of March 2021, which is a dry season. As per standards the water quality parameters have been evaluated and observed to be within the range. All the physico-chemical parameters for the samples have been studied for boreholes and hand-dug wells as all the values are observed to be within the range and are highlighted in the results.
