Managing water resources offers crucial information about the availability of water supplied from catchments into water bodies, which plays a vital role in water resource engineering. However, due to changes in the global climate, hydrological modeling of river catchments is critically crucial for socio-economic development and livelihoods. Numerous models evaluate runoff from precipitation, but the SCS-CN method is fundamental and the most widely recognized for calculating runoff. This research evaluates runoff de [...]

The ability to situate individuals within social categories provides an important social function, allowing people to navigate problems of survival and reproduction within highly complex social structures. This categorization of people with apparently shared characteristics is facilitated by various cues, one of the most important being facial information. There has been a wealth of literature that reports on perceptions of characteristics informed by faciometrics (or the measurement of facial features and associat [...]

The risk for developing a variety of malignancies is significantly elevated in the setting of lung transplantation. Malignancy remains among the three major causes of death in post-transplant recipients, and the relatively high risk of cancer development as well as metastatic aggression pose special threats to this population due to the need for continued immunosuppression. A variety of risks such as tobacco use and inflammatory lung diseases that led to the lung pathology prompting lung transplantation, in additio [...]

End Stage Renal Disease is becoming more prevalent in the United States of America, with demand for kidney transplant exceeding the available organ supply. A novel method to increase the donor pool has been to consider transplanting organs from deceased patients who have had Hepatitis C Virus (HCV) or Human Immunodeficiency Virus (HIV) infections. Transplants with HCV infected kidneys are becoming more prevalent, due to increased organ supply due to increased mortality from injection opioid use. Similarly, deceased [...]

Hydrogels are three-dimensional, hydrophilic networks of polymers with a high water absorption capacity. We investigated the removal of monovalent cationic dye, methylene blue, from aqueous solutions by a polyvinyl alcohol/Sodium alginate/Starch mix hydrogel to discover a solution to the environmental waste-water problem. By applying a gamma radiation dose from a Co-60 source without adding a hazardous cross-linker, a novel PVA/SA/Starch mix hydrogel was synthesized. The effects of factors like irradiation dose and [...]

Background: Cognitive abilities in Alzheimer’s Disease are usually examined by formal tests conducted in a laboratory or facility. Such tests are useful for determining the severity of the disease but do not indicate the types of cognition exhibited in the daily lives of patients. This study shows significant preservation of cognition and quality of life in the daily routine of a woman with severe Alzheimer’s who was given multiple therapeutic interventions. Alzheimer’s disease involves multiple d [...]

This article quantifies the recycling potential of the metallic materials that make up three-phase induction motors. The data on the use of electric motors by type and power determines that the most significant recycling potential lies in this low-voltage motor which powers up to 75 kW. The work aims to show the possibility of such recycling in the European Union (EU). The metals used to make the various parts of the induction motor and the main recycling methods that allow their reuse are listed. It evaluates whic [...]

Strongyloides stercoralis infection derived from the donor in solid organ transplant (SOT) places recipients at risk for hyperinfection syndrome and death. We describe the case of a lung transplant recipient who developed strongyloidiasis presenting with GI symptoms and progressing to diffuse alveolar hemorrhage, bacteremia and multi-organ failure. The patient's clinical course illustrates the life cycle of Strongyloides. For treatment, the patient received ivermectin and albendazole. We advocate that early diagnos [...]

Paragangliomas are rare tumors that may present with cranial neuropathies when located along the skull base. Supratentorial paragangliomas are less likely to secrete catecholamines but should be worked up, nonetheless. We highlight a case of a female in her fourth decade found to have a petroclival lesion following initial presentation that included one month of tooth pain, dysphagia, diplopia, hoarseness and right hemifacial hypoesthesia. Magnetic resonance imaging of the brain demonstrated a T2 hyperintense lesio [...]

Autism spectrum disorders (ASDs) are diagnosed on the basis of three behavioral features, namely, (1) deficits in social communication, (2) absence or delay in language and (3) stereotypy. The consensus regarding the neurological pathogenesis of ASDs is aberrant synaptogenesis and synapse function. Further, it is now widely accepted that ASD is neurodevelopmental in nature, placing emphasis on derangements occurring at the level of intra- and intercellular signaling during corticogenesis. At present, there is an ev [...]

This paper presents a three-phase full-bridge boost switch-mode rectifier (SMR) fed switched-reluctance motor (SRM) drive with energy storage buffer. First, the power circuits and control schemes of the two power stages are properly designed. Except for having good line drawn power quality, the boostable DC-link voltage of the SRM drive can enhance the SRM driving performance in wide speed range. And the recovered regenerative braking energy can be sent back to the grid successfully. Then, a battery storage system [...]

Microbial and viral pathogens have emerged as key contributors to cancer development. Research conducted in the last twenty years has significantly enhanced our comprehension of the cancer-causing capabilities of infectious agents. An illustrative instance is gastric cancer (GC), which is closely associated with Helicobacter pylori (H. pylori) and Epstein-Barr virus (EBV) infections, with approximately 90% of non-cardia GC cases attributed to H. pylori infection and around 10% linked to EBV. Despite significant res [...]
