Oguta LGA is surrounded by 44 oil wells located around different communities. Preliminary investigations indicated that crude wastes were not properly managed and oil spillage occurred regularly in the LGA. Therefore, assessment of both radionuclide contents in yam matrix and health risks in Oguta was carried out to determine possible radiological health risks associated with improper management of crude wastes, and also evaluate haematological health profile in the LGA for future reference and research. A well calibrated NaI (Tl) detector was deployed for the radiological investigation, and about 5 ml of blood samples were collected from 190 participants each from Oguta and the control LGAs for haematological assessment. Mean activity concentrations due to 40K, 226Ra and 232Th in yam samples from Oguta LGA were 189.99 ± 59.14 Bqkg-1, 23.75 ± 5.69 Bqkg-1 and 30.99 ± 9.51 Bqkg-1, respectively while mean activity concentrations due to natural radionuclides in yam samples from control LGA were 110.40 ± 78.53 Bqkg-1, 10.12 ± 3.34 Bqkg-1 and 18.39 ± 8.74 Bqkg-1 for 40K, 226Ra and 232Th, respectively. Committed effective dose equivalent values in Oguta and the control LGAs were 704.95 ± 183.30 μSvy-1 and 403.65 ± 172.19 μSvy-1, respectively which are less than world average value of 1.1 mSvy-1. Crucially, one-way ANOVA at α0.05 has indicated that effects of radiological parameters due to natural radionuclides in yam from Oguta are significantly different from effects of radiological parameters due to natural radionuclides in yam from the control LGA. However, the percentage contributions of natural radiation exposures to incidence of cancer in Oguta and the control LGAs are just 1.7% and 1.4%, respectively, and haematological investigations have shown that overall health of the communities in the study LGAs has not been compromised due to environmental and human factors. Hence, natural radioactivity may have been elevated in Oguta but the concentration levels are not yet alarming. Radiological health risks could result from consistent exposure to those natural radionuclides in the long term.
The capabilities approach, based on the work of Sen and Nussbaum, proposes a transformation in housing design by prioritizing human well-being over economic criteria. This framework assesses individuals’ real opportunities to develop fulfilling lives (“capabilities”), responding to contemporary challenges such as climate change and urbanization. Recent studies indicate that 68% of architects integrate this approach into sustainable projects (Chen, et al. Journal of Sustainable Architecture, 2023, Q1), demonstrating its relevance for creating resilient and inclusive environments. The methodology combines theoretical analysis (UTAUT model for technology adoption and the capabilities approach) with global case studies. Designs are examined that incorporate: Smart technology: IoT and AI systems for security and energy efficiency; Biophilic design: Integrating nature into interior spaces; and Net-Zero Homes (NZEH): Energy self-sufficiency through renewables. Data were collected from projects in Belgium, Australia, and the US, assessing social and environmental impact using well-being and sustainability metrics. We determined the results and discussed the approach using Positive Impact: Smart-technology homes improve autonomy in older adults by 72% (Liu, et al. Gerontology, 2022, Q1). Projects such as Savonnerie Heymans (Brussels) reduced energy consumption by 40% through solar panels and thermal insulation, while increasing social cohesion with community spaces. Biophilic design: Associated with 30% less stress and 25% higher productivity; Barriers: High initial costs (up to 20% more than conventional housing) and regulatory complexity limit widespread adoption. Furthermore, feminist and decolonial critics warn that the approach can perpetuate inequalities if it ignores sociopolitical contexts. In conclusion, the capabilities approach revolutionizes future housing by merging human well-being, sustainability, and inclusion. However, its implementation requires overcoming economic and ethical challenges: Accessibility: Universal designs for vulnerable populations. Collaborative governance: Policies that balance innovation, data privacy, and affordability. Cultural adaptation: Integration of non-Western perspectives. Projections indicate that NZEHs will grow by 40% by 2030, highlighting their potential to build equitable and resilient societies.
The article describes the necessary conditions for the phenomenon of thermal energy release in a magnetic fluid placed in a high-frequency rotating magnetic field. The minimum amplitude of the magnetic field was calculated and the thermal power released (by the rotating spherical nanoparticles in the viscous medium) was estimated. The estimations were based on the assumption that the magnetic relaxation times (τN and τB) and the magnetic field rotation period (τrot) meet the condition: τN>>τrot>>τB. The principle of operation and construction of the device generating a high-frequency rotating magnetic field is described. Preliminary experimental studies were carried out using a magnetic fluid with magnetite nanoparticles that indicated magnetic relaxation as the cause of the released heat. The value of the absorption rate in the experiment and its dependence on the strength of the magnetic field were determined.
Modern Agricultural production wants to efficiently produce plant products and benefits to meet people's needs. However, because of better plant species and varieties, overuse of fertilizer and overdose of pesticide alters the plant resources relationship, resulting in soil degradation, vegetation decline, and crop failure or waste of resources, which influence the quality of fruit and benefit and are unfavorable for the sustainable utilization of nature resources and crops high-quality development. After a couple of years of study, the results showed that Agricultural development went into agricultural high-quality development in 2017, which is to use effective measures or methods to maximize yield and benefits and meet the need of people's need for better Agricultural produce and a better life. The theory foundation of the sustainable utilization of natural resources and Agriculture high-quality production is the resources use limit by plants, vegetation carrying capacity, and critical period of plant resources relationship regulation. The methods of Agriculture high-quality development are to select excellent plant species or varieties based on site conditions and market needs before planting crop young plants and sowing seeds, adopt appropriate initial planting density when planting crop young plants and sowing seeds, and regulate the relationship between plant growth and resources need in the process of crop production in a timely and appropriate amount, especially the chemical fertilizer and pesticide to obtain the maximum yield and benefits and realize the sustainable utilization of natural resources and achieve agricultural high-quality development.
Chronic Hepatic deficiency due to the ingestion of alcohol remains as one of the main causes of morbidity and mortality in our country. From it a variety of complications arise, one of them is the Hepatopulmonary Syndrome, which usually goes unnoticed and undiagnosed; this syndrome is distinguished by the presence of hypoxemia and pulmonary vasodilation. The gold standard to establish a diagnostic is contrast-enhanced Echocardiogram. No pathognomonic sign is known for this syndrome, which leads the present elaboration to evaluate the use of orthodeoxia by pulse oximetry as a screening test in the detection of Hepatopulmonary Syndrome cases.
Introduction: Immediate postoperative gastrointestinal bleeding following bariatric bypass surgery is a major complication, and usually results from staple line hemorrhage or conventional gastro-esophageal causes. Dieulafoy`s lesion is a rare cause of gastrointestinal bleeding and is usually managed by endoscopic means. Herein we present a case of massive intraoperative bleeding resulting from gastric Dieulafoy`s lesion single anastomosis gastric bypass surgery necessitating resection of the gastric pouch. This is the first description of this complication, and the difference of such a lesion from the sporadic ones is discussed.
Discussion: Gastric bypass surgery is an effective procedure for morbid obesity. The approach we have adopted for massive upper GI hemorrhage in the immediate postoperative period should be distinguished from delayed bleeding after gastric bypass. In these latter cases, marginal ulceration is more common than bleeding from the remnant gastric pouch. It is also likely that bleeding from a Dieulafoy`s lesion following gastric bypass surgery represents a different disease compared to other Dieulafoy`s cases.
Conclusion: This is the first description of an intraoperative Dieulafoy`s lesion bleeding during the conduct of a single anastomosis gastric bypass procedure which required gastric pouch resection. Such a lesion differs from sporadic Dieulafoy`s cases, and must be considered in every case of intraoperative bleeding during gastric bypass.
Modern-day enhancements in Enterprise Architectures (EA) has increased the interoperability issues in almost all domains; these issues are increasing day-by-day as organizations are spanning and information is being exchanged between different platforms. Command Control Computer Communication and Intelligence (C4I) complex systems are also facing the interoperability issues due to highly classified and sensitive information being exchanged. In this paper we have discussed the integration of different C4I applications running under heterogeneous platforms by allowing them to communicate using a secure and ciphered web based middleware named as Web Middleware (WMW). This middleware is a client-server based web adaptor to achieve clean, systematic, secure and reliable communication. The main feature among many is the simple HTTP browser based customization that do not require any specific or special add-ons and controls to be installed on the client machine. Architecture usage, and initialization of the WMW middleware is discussed with security and performance discussion.
Tardive Dyskinesia (TD) is an iatrogenic complication caused by antipsychotic agents and rarely by other anti-depressive/antiepileptic or anti-nausea medication. It is mostly a benign condition with implications regarding esthetic issues but it can also impact social and emotional well-being. We are reporting a case in which severe TD ensued in an elderly lady with newly diagnosed dementia, who presented to the psychiatric ER with a Capgras syndrome and paranoia accompanied by behavioral disturbances. She was treated with 4 consecutive antipsychotic agents (haloperidol, brexiprazole, risperidone, and olanzapine) due to unresponsive psychosis in conjunction with biperiden and developed a severe case of TD, which was complicated by two successive episodes of jaw subluxation. In spite of the good outcome following the reduction of the subluxation, we emphasize the danger of this rare painful, and bothersome side-effect and recommend how to pharmacologically deal with the TD setting in which it occurred.
Most underwater explosions show characteristics of a bubble pulse and reverberation effects. To specifically identify the cause of an underwater explosion, it is most important to find a bubble pulse and reverberation effects using spectral and cepstral analyses. For a very shallow underwater explosion, spectral analysis is preferable to cepstral analysis. Time-domain analyses show bubble pulses as well as positive polarities of the first P-wave arrivals on the vertical component, and frequency-domain spectral analyses also clearly reveal the bubble pulse and reverberation effects. This study includes comparative studies including a Russian underwater nuclear explosion and US Navy shock trials. The ROKS Cheonan sinking was a shallow underwater explosion that occurred near the surface showing a bubble jet characteristic resulting in splitting the ship into two pieces including a bubble pulse and reverberation effects. The findings of a bubble jet and a toroidal bubble deformation including a bubble pulse are highlighted for a shallow underwater explosion in this study. The ROKS Cheonan sinking took place off the Baengnyeong Island in the Yellow Sea of the Korean Peninsula at a depth of about 8 m in the sea depth of 44 m on March 26, 2010. The explosive charge weight was estimated at 136 kg TNT which is equivalent to one of the abandoned land control mines (LCM) that were deployed near the Northern Limited Lines (NLL) in the Yellow Sea in the late 1970s.
We read with interest the case report entitled “Dieulafoy’s Lesion related massive Intraoperative Gastrointestinal Bleeding during Single Anastomosis Gastric Bypass necessitating total Gastrectomy: A Case Report” published in Archives of Surgery and Clinical Research b Ashraf Imam et al. [1]. We appreciate the authors for managing such a complicated case and for sharing their experience but, we have some conflict about the management, and we wanted to add some comments regarding the importance of EGD before bariatric surgery.
In the published case, no preoperative EGD was done and the authors mentioned that Dieulafoy’s Lesion is very unlikely to be diagnosed in the routine endoscopy. We agree with that statement but, it is not a good reason to eliminate this diagnostic modality before surgery. Though controversial, there is growing evidence which supports the importance of routine EGD prior to obesity surgery [2]. This may alter the surgical or medical plan for the obese patient, Furthermore, we have a different opinion about this patient’s management and, we wanted to share this with the authors.
In the reported patient, after control of the bleeding during gastrojejunal anastomosis, the OAGB(One Anastomosis Gastric Bypass) concluded successfully but, the patient was re-intubated because of severe bloody emesis at the recovery room and then an arterial bleeding point in the posterior wall of the lesser curvature close to the esophagogastric junction was found. This does not illustrate the reason for the huge gastric remnant seen at the laparoscopy because it was at least 200 cm far from the pouch and backwards flow of blood is very unlikely. Our opinion is, due to 90% diagnostic rate and about 75-100% success in hemostasis, on-table EGD should have a more highlighted role in treatment of the reported case [3].
Even if the pouch was dilated, it was not rational to perform a total gastrectomy in such an unstable patient and a laparoscopic pouch resection followed by Roux- en-y esophagojejunostomy could be a better choice in our point of view. Moreover, Feeding gastrostomy could be a better option rather than feeding jejunostomy, if needed.
In summary the essential role of endoscoy for screening the patients before bariatric surgery and, for the management of complications (though controversial), should always be kept in mind by bariatric surgeons.
