Joyal et al extended Theorem A to the polynomials whose coefficients are monotonic but not necessarily non-negative. In this paper, I will prove some extensions and generalizations of this result by relaxing the hypothesis.
Pharmaceutical residues: New emerging contaminants and their mitigation by nano-photocatalysis
Shah, Aarif Hussain,Rather, Mushtaq Ahmad Techno-Press 2021 Advances in nano research Vol.10 No.4
The steady growth in population has led to an enhanced water demand and immense pressure on water resources. Pharmaceutical residues (PRs) are unused or non-assimilated medicines found in water supplies that originate from the human and animal consumption of antibiotics, antipyretics, analgesics etc. These have been detected recently in sewage effluents, surface water, ground water and even in drinking water. Due to their toxicity and potential hazard to the environment, humans and aquatic life, PRs are now categorized as the emerging contaminants (ECs). India figures in the top five manufacturers of medicines in the world and every third pill consumed in the world is produced in India. Present day conventional wastewater treatment methods are ineffective and don't eliminate them completely. The use of nanotechnology via advanced oxidation processes (AOP) is one of the most effective methods for the removal of these PRs. Present study is aimed at reviewing the presence of various PRs in water supplies and also to describe the process of AOP to overcome their threat. This study is also very important in view of World Health Organization report confirming more than 30 million cases of COVID-19 worldwide. This will lead to an alleviated use of antibiotics, antipyretics etc. and their subsequent occurrence in water bodies. Need of the hour is to devise a proper treatment strategy and a decision thereof by the policymakers to overcome the possible threat to the environment and health of humans and aquatic life.

Background/Aims: This study aimed to study the endoscopic yield, appropriateness, and complications of pediatric endoscopyperformed by adult gastroenterologists in an adult endoscopic suite. Methods: This a retrospective study in which records of all the patients less than 18 years of age who underwent endoscopy in the last5 years were studied. The indications of endoscopy in children were categorized as appropriate or inappropriate per the latest guidelinesby American Society for Gastrointestinal Endoscopy and North American Society for Pediatric Gastroenterology, Hepatology andNutrition. Positive endoscopic yield was defined as the presence of any abnormality on endoscopy. Results: Among the total of 822 children (age <18 years), the most common indications were variceal surveillance/eradication in 157(19.1%), followed by dyspepsia in 143 (17.4%), upper gastrointestinal (UGI) bleeding in 136 (16.5%), recurrent abdominal pain in 94(11.4%), unexplained anemia in 74 (9%), recurrent vomiting in 50 (6.08%), chronic refractory gastroesophageal reflux disease in 34 (4.1%)and others; 780 out of 822 endoscopic procedures (94.9%) done in children were appropriate as per the guidelines. The endoscopicyield was 45.8%, highest in patients with UGI bleeding (71.3%), followed by variceal surveillance (54.8%), recurrent vomiting (38%),dyspepsia (37.8%), and recurrent abdominal pain (36%). Minor adverse events occurred in 7.3% of children. Conclusions: Pediatric endoscopy performed by an experienced adult gastroenterologist may be acceptable if done in cooperation witha pediatrician.

In this paper, we propose a routing technique that takes into account the importance of a particular node for the overall network connectivity for routing. We show that some nodes are more important than others and need to be used sporadically for data forwarding. Avoiding the use of such important nodes results in prolonging network lifetime and maximizing the data transfer. Simulation results are shown to confirm the effectiveness of the proposed technique.
