Exposure to microplastics is unavoidable, and a vast amount of microplastics are traveling around the oceans. Microplastics are considered one of the major potential pollutants due to their exposure and interference with the health of humans, animals, aquatic species, agriculture, etc. Shockingly, the microplastic was also detected in the human placenta (fetal and amniochorial membranes), which could cause long-term effects on human health. The disposal of plastic into the oceans is the most happening process across the globe; thereby, microplastic pollution is evident, leading to a huge risk to marine species. Also, the accumulation of microplastics on soil or land leads to an increase in pH value, thereby affecting the surface water and soil-groundwater medium, eventually affecting plant and human health. At the same time, microplastics and their particles are found in milk, meat, and other edible items, which directly affects human health. The appearance of microplastic particles in insects, birds, animals, and even human blood indicates its adverse effect on the environment. This review has discussed the impact of microplastic on the health of humans, aquatic species, and agriculture.

Aquaculture may simply be referred as “Underwater Agriculture.”India is a major maritime state and an important aquaculture- based country in the worldhaving major aquaculture activitiesin the production of Carp from Freshwater,Shrimp from Brackish water, etc. Feed requirements of fish vary in quantity and quality according to the feeding habits, physiological stages of the species and environmental variations viz., temperature; amount and type of natural food availability in the culture system.A nutritious and cheap feed is a pre requested for profitable aquaculture. Though, use of commercially available feed is in practice in many countries. The feed cost consumes more Than half of running expenditure. Therefore, the search of nutritionally well-balanced feed Prepared from very cheap locally available ingredients in progress in all the aqua farming countries. In the present study, an attempt has been made to well-balanced nutritious feed Particularly from the locally available cheaper ingredients. The objectives of the present study are: to assess the effect of feed on the growth of finfish and shellfish in the laboratory, to prepare the conventional feed with traditional ingredients and to check the effect of feed on the growth performance of ornamental fish - Guppy, Poecilia reticulata.

Background: Worldwide, obesity in adolescents is an epidemiological concern. Overweight and obesity are associated with comorbidities in adult life, such as increased risk of hypertension and other non-communicable diseases. This study investigated possible differences between traditional lipid markers and Low-Density Lipoprotein (LDL) and High-Density Lipoprotein (HDL) subfractions in a population-wide representative sample of Brazilian adolescents. Methods: The individuals included in the study comprise a subsample of the 2015 Health Survey of São Paulo (ISA-Capital 2015). LDL and HDL particle sizes were determined by the Lipoprint® System (Quantimetrix Corporation). Results: 272 Brazilian adolescents with a mean age of 15.2 ± 2.2 years, of which 47.8% (n = 130) are boys. Analysis of LDL subfractions showed an increase in LDL 2 content in girls (5.7% vs. 5.1%; p = 0.047). This result was associated with a higher content of large LDL in girls (17.8% vs. 13.5%; p < 0.001) and a significant, lower content of small LDL (1.7% vs. 3.4%; p = 0.002). When obesity was considered, we observed that regardless of being overweight, girls had higher large and small LDL than boys. However, when a large to small LDL ratio was calculated, girls with no excess weight had higher values than boys with no excess weight (10.6 vs. 9.3; p = 0.038), and these had lower LDL ratio than overweight boys (9.3 vs. 13.5; p = 0.016). On the other hand, boys had higher HDL 2 content than girls (8.9% vs. 8.0%; p = 0.017), which was associated with increased large HDL values in boys (1.9% vs. 1.7%; p = 0.047). Regression analysis was performed according to gender, the sum of very low-density lipoprotein (VLDL) + intermediate density lipoprotein (IDL) C + IDL B subfractions was adjusted for age and body mass index (BMI), showing that girls had lower atherogenic lipid profile (β = 0.987; CI = 0.977-0.998; p = 0.017) than boys. When the regression analysis was performed according to BMI, large LDL in adolescents with no excess weight presented a lower atherogenic lipid profile (β = 1.040; CI = 1.000-1.082; p = 0.049), adjusted for age and sex, than overweight adolescents.Conclusion: Regardless of excess weight, girls showed a cardioprotective profile more associated with a favorable distribution of LDL subfractions than boys, reinforcing the relevance of evaluating qualitative aspects of lipoproteins in addition to the traditional cholesterol content.

The physiological removal of foreign bodies in the horse’s external ear canal is best achieved by head-shaking. However, external otitis in the horse induces moderate to severe pain: therefore, the horse does not shake his head. The causes of external otitis are dust, water in the external ear canal, keratin, and ceruminous debris. The clinical symptoms are ear discharge, skittishness, facial nerve paresis, and/or head tilt. After the horse has been sedated, the most important diagnostic procedure is the endoscopy of the cartilaginous and osseous part of the external ear canal, including the evaluation of the transparency of the tympanic membrane. The clinical complications of external otitis are hearing loss, facial nerve paresis, head tilt, hypertrophy of the tympanostylohyoideum, and corneal ulcers. The most important treatment is soaking up the exudate in the osseous part of the external ear canal using small cotton balls which are held by the foreign body forceps of the endoscope. Based on the results of the culture of exudate and the antibiogram, an antibacterial drug must be administered orally for 3 to 4 weeks. At this time, an endoscopy of the external ear canals and guttural pouches also has to be done. Based on the outcome of the endoscopy, endoscopic and clinical investigations have to be performed six months later as well. Only 7/19 horses had a normal osseous part of the external ear canal with a transparent tympanic membrane, including normal hearing measured by the brainstem auditory-evoked response after one month of treatment.

This paper investigates the effect of coating concentration (ppm), and coating thickness (µm) on the anti-microbial properties of polycarbonate sheets using a variety of anti-microbial agents (Cu-infused Mg(OH)2, Mg(OH)2, Cu(OH)2, MgO, CuCl2.2H2O, and ZnO). In addition, a complete analysis was performed for all agents to rank the best agent in terms of the highest anti-microbial performance against E. coli K-12 MG1655 in two time intervals (4 and 24 hours). The coating concentration (ppm) was found to be a significant factor in the anti-microbial characteristics for Cu-infused Mg(OH)2, Mg(OH)2, Cu(OH)2, MgO, CuCl2.2H2O, and ZnO (p = 0.004, p < 0.0001, p < 0.0001, p = 0.0297, p = 0.0011, and p = 0.0130 respectively). The coating thickness (µm), on the other hand, was found to be a major contributor to the anti-microbial properties of Cu-infused Mg(OH)2, Mg(OH)2, Cu(OH)2, MgO, and CuCl2.2H2O (p < 0.0001, p = 0.0004, p = 0.0011, p = 0.0310, and p < 0.0001 respectively). The analysis determined that the coating did not influence the anti-microbial properties of ZnO. The interaction between the coating concentration (ppm), and the coating thickness (µm) was found to be a significant factor for Cu-infused Mg(OH)2, Cu(OH)2, MgO, CuCl2.2H2O, and ZnO (p < 0.0001, p = 0.0001, p = 0.0004, p < 0.0001, and p < 0.0001 respectively), however, this was not a significant factor for Mg(OH)2.Highlights•    The anti-microbial activity of the inorganic material is dependent on the particle shape and size.•    Particles with sharp edges will provide additional physical injuries to the microorganisms.•    Smaller particle size will provide higher surface area therefore better interaction with microorganisms.•    The coating concentration and coating thickness will be crucial to the anti-microbial activity.•    The thermal embossing techniques demonstrate good adhesion to the surface.

Background: Myiasis is a parasitic infestation of livestock animals caused by dipteran larvae. The presence of wounds, lack of hygiene on the farm, and temperate climatic conditions contribute to myiasis. Swine can be infested by myiasis if injured pigs are not treated properly and failure to treat myiasis in time may cause the culling or death of the pigs, resulting in huge economic loss to the farmers. But like humans and other farm animals, pigs also deserve to be treated and cured of any suffering or disease. Therefore, this study is documented on pig myiasis and its management because to date a few cases have been reported on it.Case presentation: This case report documented the successful management of neck myiasis in a male, 9-month-old, 12-kg-weighing backyard pig. The wound site was cleaned using antiseptics and maggots were removed. The site was treated with turpentine oil, and ivermectin at 0.2 mg/kg B.W. and S/C. A combination of streptomycin (12.5 mg/kg B.W.) and penicillin (20000 IU/kg B.W.) was used IM daily for 5 days to prevent secondary bacterial infection. The wound was dressed regularly on every alternate day until the complete removal of maggots and the formation of granulation tissue.Conclusion: Through proper therapeutic management, the backyard pig’s neck myiasis wound was successfully healed in 10 days without any complications.

Fine Dust (FD) in the respiratory air generates a variety of human disease issues throughout the earth. This study aimed to investigate whether (1) Tussilago farfara extracts (TF) decrease neutrophils accumulation, typical pathological features, and goblet cell hyperplasia in mice following exposure to fine dust (FD); (2) inflammatory cytokines result from FD exposure; and (3) asymmetric dimethyl-arginine (ADMA) and symmetric dimethyl-arginine (SDMA) levels in the mice following exposure to FD. Seven-week-old male Balb/c mice (n = 5/group) were instilled two times by intra-nasal-trachea (INT) injection for 3 days and 6 days to the mice four groups; normal, control, FD + dexamethasone (Dexa, positive control), and FD + TF groups. TF suspended in 0.5% carboxymethyl cellulose (CMC) was administered orally to the mice daily for 10 days (100 mg/kg). Neutrophil accumulation, typical pathological features, goblet cell hyperplasia, ADMA, and SDMA levels were assessed on day 10 in FD-induced mice. Results indicated FD significantly reduced neutrophil accumulation in BALF, typical pathological features containing goblet cell hyperplasia in lung tissues, and inflammatory cytokines [interleukin (IL)-17 and tumor necrosis factor-α (TNF-α), macrophage inflammatory protein-2 (MIP-2) and C-X-C motif chemokine 1 (CXCL-1)]. Furthermore, TF significantly decreased levels of elevated ADMA and SDMA by FD exposure. Collectively, TF decreased the counts of neutrophils in BALF, histological changes in lung tissues due to downstream secretion of inflammatory cytokines, and levels of ADMA and SDMA. Therefore, TF may be a potential therapeutics for treating FD-associated diseases.

Background: Idiopathic intracranial hypertension (IIH or pseudotumor cerebri) has two major morbidities: papilledema with visual loss and disabling headache. Intracranial Venous Hypertension (IVH) is a fundamental mechanism of IIH. Although traditionally considered limiting to the central nervous system, evidence suggests IIH as a systemic disease associated with cardiorespiratory disorders, which has been far less comprehended. Case Report: A 60-year-old female with Chronic Obstructive Pulmonary Disease (COPD) was admitted for dyspnea and developed a coma with a pH of 7.01 and pCO2 of 158 mmHg. She was intubated and had persistent nuchal rigidity, a brief myoclonus episode with a negative electroencephalogram, and negative CT head studies. A Lumbar Puncture (LP) revealed elevated opening pressure (35 cmH2O) with normal Cerebral Spinal Fluid (CSF) studies. Her nuchal rigidity improved after the removal of 40 mL CSF. The ophthalmology examination the next day after her the large volume LP didn’t show visual loss or papilledema. The patient improved clinically and was extubated two days later. Her echocardiogram showed a dilated right ventricle with pulmonary hypertension. The patient was discharged home.Discussion: IIH is different from hypercapnic encephalopathy and characterized by increased intracranial pressure with papilledema, vision loss, and debilitating headache. Hypercapnia-induced increased intracranial venous flow and pulmonary hypertension-caused elevated central venous pressure with consequent outflow resistance lead to IVH. In hypercapnic encephalopathy, the presentation is mostly cognitive changes. In this case, nuchal rigidity with a negative CT head scan triggered the investigation of IIH. Conclusion: A deep understanding of the relationship between COPD and IIH is vital. There is insufficient evidence to recommend routine eye examinations in COPD patients for papilledema and to conduct a pulmonary function test for a newly diagnosed IIH patient. However, we highly suggest a timely ophthalmology exam prior to performing an LP in COPD patients with suspecting IIH to avoid unnecessary procedures and meanwhile improve clinical outcomes.

Background: Tailored adjuvant treatment is key to managing endometrial cancer effectively. Understanding prognostic factors of loco-regional failure and the impact of adjuvant treatment can help in treatment de-escalation without compromising survival outcomes.The aim of this study was to assess the pattern of failure in endometrial cancer patients and to determine predicting Loco-Regional Recurrence (LRR) factors.Patients and methods: Data were collected from 214 patients treated for endometrial cancer between 2005 and 2012 in Salah Azaiez Institute in Tunisia. All patients underwent upfront surgery followed by adjuvant brachytherapy with or without external beam radiation. The median follow-up period was 44 months. Univariate and multivariate analyses were performed to identify prognostic factors for LRR.Results: The 5-year overall survival rate was 78.1%, and the 5-year progression-free survival rate was 80.1%. LRR occurred in 25 patients (11.6%), with a median recurrence time of 29 months (range 4 months - 46 months). Pelvic relapse was the most common site, occurring in 10 patients. Vaginal relapses were observed in 9 patients, and retro-peritoneal relapses were observed in 6 cases. FIGO stage, tumor grade, histologic type, Lympho-Vascular Space Invasion (LVSI), and delays in adjuvant treatment were significant predictors of LRR.Conclusion: Identifying prognostic factors for LRR in endometrial cancer is crucial for optimizing adjuvant treatment strategies. Higher FIGO stages and the presence of LVSI were independent predictive factors for LRR. Tailored adjuvant treatment, taking these prognostic factors into account, is essential to improve patient outcomes and minimize unnecessary treatment-related toxicity.

Medicines are used to cure and treat ailments, relieve or eliminate disease symptoms, and slow down the disease process. Any attempt to disrupt this natural medicine process, using falsified medications, spells doom to a consumer of such medication. The challenge of fake medicines is a global one and affects developing and developed nations and currently assumes great significance as a result of globalization challenges, which have flattened the entire world, hence removing barriers to the movement of products and services. The cross-sectional survey was conducted, using six local government areas of Anambra State in South-East Nigeria, namely Awka, Nnewi, Onitsha, Aguata, Ogbaru, and Anaocha, among adults aged 18 years and above. A minimum sample size of 500 was calculated and stratified sampling was employed to select respondents in order to ensure that various population groups, the upper class, middle class, and lower class were represented.This research has shown that falsified medicine is an evil wind that blows nobody any good. It negatively affects every aspect of the citizen’s livelihood, ranging from their health, which manifests as treatment failures, deformities, loss of life to death, to loss of confidence in the healthcare providers, revenue losses to individuals, healthcare providers, manufacturers, and finally corruption of the genuine medicines supply chain with fake and adulterated medicines.The study has clearly shown the experiences of residents of Anambra State, South-East Nigeria with fake and adulterated medicines and also services as a wake-up call to medicines regulators like NAFDAC, PCN, the PSN, and Federal Ministry of Health to declare a state of emergency on the fight against fake and adulterated medicines and make enabling laws that are punitive enough towards the fight against this scourge, so that the healthcare and well-being of Nigerians would be assured at all times.

Objective: To study the therapeutic effect of B-ultrasound-guided intrahepatic infusion of autologous bone marrow nucleated cells on decompensated cirrhosis. Methods: To observe the clinical treatment of 75 cases of decompensated cirrhosis. Among them, 30 cases received routine liver protection and diuretic treatment. 45 cases were treated by percutaneous transhepatic infusion of autologous bone marrow nucleated cells under the guidance of B ultrasound. There were no significant differences in liver function and blood routine indexes between the two groups before treatment (p > 0.05). Results: The indexes of liver function and blood routine at different time periods of 1 month, 3 months, 6 months, and 12 months in the conventional treatment group did not change significantly. 6 cases died of liver failure within 1 year, the fatality rate was 20%. The indexes of liver function and blood routine of percutaneous liver transhepatic infusion of autologous bone marrow nucleated cells at 1 month, 3 months, 6 months, and 12 months under the guidance of B-ultrasound were significantly better than those of the conventional treatment group (p < 0.05). One case died of gastrointestinal bleeding in the group of percutaneous transhepatic infusion of autologous bone marrow nucleated cells guided by B ultrasound, with a fatality rate of 2.5%. Compared with the conventional treatment group, there were significant differences (p < 0.05). Conclusion: Conventional drug therapy has no obvious effect on decompensated cirrhosis. Intrahepatic infusion of bone marrow nucleated cells can significantly promote liver function reconstruction in decompensated cirrhosis.

Deinococcus radiodurans (D. radiodurans) was accidentally discovered in 1956 when cans of ground meat were exposed to massive doses of ionizing gamma radiation, intended to kill dangerous bacteria. The bacterium can survive doses of radiation, even up to 1,000 times that which is deadly to humans. Among biologists and biophysicists, D. radiodurans is often humorously called “Conan the Bacterium.” This extreme radioresistance of the bacterium has been attributed to its ability to protect the proteome from ROS, which originates from water radiolysis, and also to carry out the effective repair of a large amount of DNA damage.

After kidney transplantation, BK polyomavirus reactivation can manifest as nephropathy in 1% to 10% of patients. PCR testing of urine and blood is commonly used to screen for BK polyomavirus nephropathy. The study aims to detect BK virus infection in kidney transplant patients to prevent tubulointerstitial nephropathy and graft loss. This retrospective study includes 26 patients who underwent kidney transplants between January 2019 and December 2023. We diagnosed BK virus infection by performing real-time PCR on blood and urine samples. BKV DNA was detected in 3 patients. Reducing immunosuppressive therapy led to negative PCR results and favorable clinical and biological outcomes in these 3 patients.

Mesenchymal stem cell (MSC) transplantation may be an alternative to liver transplantation for patients with end-stage liver disease. A 24-year-old patient with Hepatic Encephalopathy due to alcoholic liver cirrhosis underwent UCMSC transplantation because there were no donors available for liver transplants involving adult deceased and living individuals. The patient was given allogeneic Umbilical cord-derived MSCs, which were then cultured following accepted practices. Subsequently, the UCMSCs were infused through the intravenous route 3 times at the interval of 30 days. Serum bilirubin, globulin, and ammonia levels were improved after the infusion and the morphology of the liver and spleen had also improved.

Introduction: Childhood obesity is one of the current themes of medical research, being considered not so much a multidimensional condition but primarily a real problem of worldwide interest.The aim of our randomized study was to evaluate and compare the effects of physical exercise associated with an educational program on clinical-functional status in overweight and obese children.Material and method: Participants were children hospitalized, through the emergency service, in the Pediatric Department, Craiova Municipal Clinical Hospital, between June and November 2023. 93 overweight and obese children, aged between 2 and 16 years, were evaluated (clinical, paraclinical and functional) by a multidisciplinary team and randomized into the control group (group C – 63 children) and the study group (group S – 30 children). After the resolution of the acute digestive or respiratory disease, the children in group S underwent a program to restore their functional status, based on educational measures (following the 5-2-1-0 rule) and physical exercises, for 12 weeks. Anthropometric data were measured (height, weight, body mass index); physical performance wasevaluated by gait analysis (we used the BTS G – WALK / BTS G – SENSOR 2 system, BTS Bioengineering Corp, Italy) with the determination of four parameters – the Timed Up-and-Go (TUG) test, the symmetry index, the walking test six minutes (6 MWT) and walking cadence or average cadence (steps/min) in both groups of children.The results were obtained by analyzing the differences in values obtained in the two moments T1 (initial) and T2 (after three months). The proportion of girls and boys was approximately equal within obesity class in each study group. Although we did not obtain statistically significant differences between the monitored parameters, between the two groups, for the two evaluation moments, the children in Group S had a clearly favorable evolution for physical performance parameters, whose average value was improved in T2. Anthropometric data did not change.Conclusion: The present study confirms the effectiveness of the multimodal (educational-kinetic) program for the physical performance of overweight/obese children. The sustained running of the program at home, with the involvement of the family and the school environment, is essential for the well-being of these children, with a favorable impact on the quality of life later.

The study is based on the characterization of different AI models applied in the public furniture design analyzing the conditions of risk, materiality, and integration of variables in two AI generative modeling algorithms. As risky since they contain flood-prone areas, low vegetation coverage, and underdevelopment of infrastructure; therefore, these characterizations are tested through artificial simulation. The experimental method is applied through laboratory tests of various material components and their structuring in 3D simulators to check their resistance and risk scenarios. The case study of one of the most risky and populated areas of the informal settlement area of the Northwest of Guayaquil, such as the Coop, is analyzed. Sergio Toral is the focal point for on-site testing. It is concluded that the generation of a planned scheme of ecological furniture with different materials responds more effectively to the territory and that through artificial simulation an advantage can be obtained in terms of execution time and results, thus demonstrating that artificial intelligence is an ideal tool. To generate furniture design proposals that are more diverse, innovative, and functional with the environment, but it generates a minimum level of error for specific designs in the experimental model_01 of 0.1% to 3% and a high level in the experimental model_02 with an increasing error from 20% to 70%. As a future line of research, it is proposed to generate a simulated system of all the new informal settlements in Guayaquil and establish focal points for the implementation of new ecological furniture.

Bloodstain Pattern Analysis (BPA) is a crucial forensic technique in crime scene investigation, employing the interpretation of blood spatter patterns to reconstruct event sequences and determine spatial relationships between victims and surfaces. This study explores BPA’s application in forensic science, emphasizing its role in establishing links between crimes and culprits, as posited by Edmond Locard’s exchange principle. The research examines how bloodstain shape, size, and distribution reveal critical information about impact angles, areas of convergence, and points of origin, while also providing insights into blood flow direction, force applied, suspect positioning, and weapons used. The investigation delves into various bloodstain types, including void patterns, spikes, and satellite stains, and their formation on different surfaces. To enhance understanding of blood behaviour from various sources, the study compares blood samples from three species: human (Homo sapiens), obtained from a professional doctor from discarded piles with precaution from a government hospital in Laxmangarh, Rajasthan and goat (Capra aegagrus hircus), and chicken (Gallus gallus domesticus), obtained from butcher shops in Laxmangarh, Rajasthan. The experimental setup involves dropping blood from a height of 50 centimetre’s and measuring the resulting stain dimensions. This comprehensive approach to BPA research aims to refine crime scene analysis techniques, ultimately contributing to more accurate event reconstructions and enhanced forensic investigations. The study underscores the importance of BPA in modern forensic science while acknowledging the need for its integration with other investigative methods to ensure robust and reliable crime scene interpretations.

Social insects have eradicated the instincts inherited from their solitary ancestors that were harmful to communities. The elimination of these instincts was accomplished by natural selection, the units of which were communities. Man has not yet eradicated the instincts inherited from their solitary animal ancestors that were harmful to communities. But their eradication is underway. And it is also being accomplished by natural selection, the units of which are societies. Completion of evolution in this direction will probably lead to the disappearance of human instincts harmful to society, as they have disappeared in social insects. This will happen after a period of time measured not by historical standards, but by geological.

A significant obstacle to agricultural productivity that jeopardizes the availability of food is crop diseases and farmer livelihoods by reducing crop yields. Traditional visual assessment methods for disease diagnosis are effective but complex, often requiring expert observers. Recent advancements in deep learning indicate the potential for increasing accuracy and automating disease identification. Developing accessible diagnostic tools, such as web applications leveraging CNNs, can provide farmers with efficient and accurate disease identification, especially in regions with limited access to advanced diagnostic technologies. The main goal is to develop a productive system that can recognize tomato plant diseases. The model was trained on a collection of images of healthy and damaged tomato leaves from PlantVillage using transfer learning techniques. The images from the dataset were cleansed by resizing them from 256 × 256 to 224 × 224 to match the dimensions used in pre-trained models using min-max normalization. An evaluation of VGG16, VGG19, and DenseNet121 models based on performance accuracy and loss value for 7 categories of tomatoes guided the selection of the most effective model for practical application. VGG16 achieved 84.54% accuracy, VGG19 achieved 84.62%, and DenseNet121 achieved 98.28%, making DenseNet121 the chosen model due to its highest performance accuracy. The web application development based on the DenseNet121 architecture was integrated using the Django web framework, which is built on Python. This enables real-time disease diagnosis for uploaded images of tomato leaves. The proposed system allows early detection and diagnosis of tomato plant diseases, helping to mitigate crop losses. This supports sustainable farming practices and increases agricultural productivity.

Wheat bran and groundnut shell powder have been used to study the mechanism of diclofenac sodium adsorption from aqueous solution using batch as well as column modes and maximum uptake is 84.3% for wheat bran and 82.4% for groundnut shell powder at pH 6, drug concentration 1mg/L at 298 K for 30min. Isotherm and error analysis reveals that Freundlich and Langmuir isotherms fitted well. Kinetic studies show that the adsorption process follows second-order kinetics and thermodynamic study shows endothermic adsorption process. Column adsorption study is important for industrial scale adsorption and column studies have been carried out using vertical bed and sequential bed adsorption columns at pH 6 which is the optimum pH for maximum adsorption for batch experiments. Vertical and sequential bed columns setup is simple and economical which provides flow under gravity. The effect of varying inlet feed concentration and flow rate on the breakthrough and exhaustion time of columns has been studied to determine the bed capacities of both columns. Thomas model and Yoon-Nelson models fitted well with experimental data for continuous flow column studies.
