On the impact of debris accumulation on power production of marine hydrokinetic turbines: insights gained via les

We present a series of large-eddy simulations to systematically investigate the impact of debris accumulation on the hydrodynamics and power production of a utility-scale marine hydrokinetic (MHK) turbine under various debris loads lodged on the upstream face of the turbine tower. The turbine blades are modeled using turbine resolving, actuator line, and actuator surface methods. Moreover, the influence of debris on the flow field is captured by directly resolving individual logs and employing a novel debris model. Analyzing the hydrodynamics effects of various debris accumulations, we show that an increase in the density of debris accumulation leads to more flow bypassing beneath the turbine blade. This, in turn, reduces the flow momentum that reaches the MHK blades at the lower depths, inducing significant fluctuation in power production. Further, it is shown that debris-induced turbulent fluctuations contribute to significant variability in the MHK turbine’s power production.

Air pollution, health outcomes, and environmental justice in the mid-atlantic state city: a public health lesson from a 15-year perspective (2005-2019)

The city that never sleeps, a vibrant tapestry of dense neighborhoods and relentless energy, has long grappled with the pervasive challenge of air pollution. The very dynamism that defines the city – its traffic, buildings, and industry – contributes to ambient concentrations of fine particulate matter (PM2.5) and ground-level ozone (O3), pollutants known to exact a heavy toll on public health. [1-3] An extended analysis of environmental health data from 2005 to 2019, meticulously compiled by the town Department of Health and Mental Hygiene (DOHMH), offers a crucial lens through which to view the city's journey: a narrative marked by significant public health victories interwoven with stark, persistent environmental injustices. [4] This fifteen-year period reveals not just the efficacy of targeted interventions but also the deeply entrenched disparities that continue to leave vulnerable communities uneasy. Thus, the aforementioned challenge provides a very important lesson to address similar problems around the globe, especially in the crowded urban areas.

Akshaya patra model: feeding knowledge hungry children

While today, he was ready to serve 1.4 million meals for schoolchildren, Mr.CC Das, Program Director, Akshaya Patra Foundation from Bangalore also faced the challenges 15-years before its establishment like any other start-up. Similar was the case of Mr.Trilok Gautam, Executive Supervisor, who was working in a remote village called Baran in Rajasthan. On his visit during the mid-day meal preparation, he was inspecting the quality of meal, where women were busy in preparing food. They were preparing bread by rolling the dough, while few were chopping vegetables with utmost hygienic care. Cleaner, safer, quality meal was to be prepared and served for 1,500 poor students. These children earlier used to go hungry from the school. On November 28th 2001, Supreme Court of India gave a verdict and directed the State Government and Union Territories to provide mid-day meal to every child in Government and Government-assisted primary schools. The Right to Food Law emerged as a fundamental right, enforced due to constitutional amendment under Article 32 of the constitution. Hence, every State Government geared up to make the mid-day meal scheme successful in their respective States. The Karnataka government also participated and named this programme as ‘Akshara Dashoha’. Government of Karnataka took the pioneering step to involve NGOs like Akshaya Patra as an important partner of the government to run this innovative mid-day meal scheme under the Public Private Partnership (PPP) Model. Presently, Indian mid-day meal scheme considered as one of the largest mid-day meal programme in the world has a target to reach out nearly 120 million children in the country.

Linkage planning of qtl for agronomic and root qualities utilizing ib370 × mas25 (oryza sativa l.)‑f2 population developed under water restricted conditions

Abstract In the existing investigation, experiments were carried out to assess the F2 population’s resultant of crosses between improved Basmati 370 and MAS25 for various agronomical and root traits cultivated under aerobic water conditions. Large variations for grain yield, root length, root dry biomass, root thickness and length/breadth ratio of grain have been displayed in segregating F2 populations. A close examination of phenotypic correlation exhibited that in the F2 population, root length was certainly matched up (r = 0.496) with root thickness. A DNA fingerprinting catalog for the currently studied F2 generation was arranged using 61 polymorphic SSR markers. Composite Interval Mapping (CIM) inspection with WinQTL cartographer version 2.5 disclosed 13 putative QTL (Quantitative Trait Loci), out of which 6 QTL were for root characters 7 QTL for agronomical characters situated on 1, 2, 3, 8 and 10 chromosomes. The QTL documented in the above-said generation, some promising F2 plants were also scrutinized and found in the homozygous or heterozygous state with high repetitions.

Proactive and reactive styles of palestinian presidents leadership in times of crisis

Crises are unavoidable which makes response an imperative matter. Thus, the proactive style becomes an indispensable part of the readiness and preparedness in any potential crisis and can help prevent it. Besides, the reactive style is still important to deal effectively with a crisis especially regarding its recovery. Proactive and reactive styles were needed by Palestinian Presidents due to the occurrence of various crises faced by them. This study examines both proactive and reactive styles used by the Palestinian Presidents leadership during crisis. Besides, it examines how the Palestinian Presidents used these styles to deal with different crises at different times. This study used content analysis on the news stories from the New Straits Times. A total of 313 stories from1996 to 2016 pertaining to proactive and reactive styles used by Palestinian Presidents were found. The stories that included reactive style figured 67.7%, while the stories that included proactive style totaled 32.3%. For President Arafat, a total of 63% of the stories included reactive style compared to 37% of the stories that included proactive style. For President Abbas, a total of 78.4% of the stories contained reactive style compared to 21.6% that contained proactive style. Proactive style has been used only in political crises, while reactive style has been used in all crises. Providing various scenarios in dealing with crises allows other organizations and individuals to be initiative in dealing with any similar future crises. This study serves as a guideline for choosing proper prospective measures and responses to crises.

Religion and ethical standards; the nexus in nigeria's democratic system and social -entrepreneurship perspectives

Nigeria is well known as a religious country where practically the citizens belong to one form of religion or the other unfortunately, the degrees of religious practces have not transformed into quality social, political, and economic lives for the people in terms of good governance, better standard of living, high ethical standards among others. It is descriptive research done as an exploratory paper in a mixed-method approach where some research questions were answered. Since ethical standards are predicated on simply knowing and doing what is good in doing to others what you will want done to you, people who claim to be religious as Nigerians should do better in this regard and many more given their faith. The effort to achieve this social rebirth can be achieved through social- entrepreneurship efforts this paper is advocating.

Bleomycin pulmonary toxicity in patients with germ cell tumors treated with bleomycin containing regimens: experience with 4 cases

Background: Information on Bleomycin pulmonary toxicity (BPT) in Qatar is scarce. The aim of this study was to estimate the prevalence of BPT and to describe its clinical significance and outcome in germ cell tumor (GCT) patients who received bleomycin-containing regimens.Methods: This retrospective cross-sectional study was conducted at the National Center for Cancer Care and Research. It included all patients diagnosed with GCT and treated with a bleomycin-containing regimen between January 2002 and December 2008 Results: We identified fourteen patients with GCT who received bleomycin containing regimen. Four of them (28.5%) had developed BPT, and they were males with mean age of 39.3±8.3 years (range: 25-46 years). The calculated creatinine clearance before treatment was normal in the 4 cases. Evaluation of the chest computed tomography scan before starting bleomycin containing regimens revealed that none of our patients had pre-existing parenchymal lung disease. The mean cumulative bleomycin dose was 187.5± 153.7 U, while the mean time to onset of BPT was 3.5±2.1 months. Once the diagnosis of BPT was established, bleomycin was discontinued in the four patients and short courses of dexamethasone were administered. Two patients (50%) died, while one patient survived with a fibrosis sequel, and the fourth patient recovered without a fibrosis sequel. Conclusion: BPT is one of the life-threatening side effects of this drug that every doctor should be aware of when treating GCT, therefore, a high index of suspicious is needed for early recognition of BPTs.

An analytical overview of covid 2019- a scientific discussion, international journal of creative research thoughts

Corona virus pandemic has swept a major section of the world population. In terms of infectivity it�s higher than any pandemic in the recent past. Corona virus, a member of the family Coronaviridae, spread from bat to human through an intermediate host pangolin. It has lower mortality rate than the previous pandemics in last 100 years such as Spanish Flu(1918-20),Asian Flu (1957-58), SARS Corona virus (SARS-Cov) (2003), H1N1 Swine Flu Pandemic(2009-10), Middle East Respiratory Syndrome (MERS) (2012), West African Ebola (2014-16) etc. Research shows Covid spike attaches ACE2 receptor; it leads to a release of cytokine into the blood capillaries near the alveoli and may ultimately turn into pneumonia. The alveoli get collapsed leading ARDF. The pulmonary inflammation proceeds to systemic inflammation that causes multiple organ failure. Drug like Chloroquine, Lopinavir/ritonavir, and Remdesivir may halt the spread of the virus in the body. Antipyretic is prescribed to reduce the temperature. This article comprises of detail mechanism of the dreadful disease along with its diagnosis and proposed treatment. This exploratory study mainly designed to generate awareness and provide information to the individuals who want to know the A to Z of Covid in nutshell. This article may create a pathway to number of upcoming scientific researches and may attract them to work on this field to enhance the probability of inventing appropriate vaccine and medicine to fight against this contagious disease and to win the battle against this Global Pandemic.

Vitamin d deficiency and anemia among pharmacy students

Prevalence of hypovitaminosis D is not restricted to the elderly and hospitalized population. Worldwide, the rate of prevalence of vitamin D deficiency has grown up rapidly in adults over the past decades. Among Libyan population including young students may has a high risk of vitamin D deficiency. The aims of this study were to examine vitamin D status among pharmacy students of Sebha University and to study the hematological profile as well as correlation of vitamin D deficiency with incidence of anemia among the students. This study was carried out on Pharmacy students from 13th January to 12th March, 2020. This is a cross-sectional study designed to determine vitamin D status among healthy young pharmacy students studying at the Sebha University. The blood samples were collected randomly from 62 pharmacy students to analysis complete blood count and 25-hydroxyvitamin D. The concentration of hemoglobin on total student was 12.5 ± 1.9 g/dl which was normal according to the WHO level (12.0 g/dl). Out of total, 36 students (59.1%) were found to have normal hemoglobin concentration (13.7 ± 1.4 g/dl) and 26 students (40.9 %) were found to have low hemoglobin concentration (10.8 ± 1.1 g/dl). Other blood profile as HCT, MCV, MHC and MCHC where statistically significant lower but the counts of RBCs, WBC and platelets were not on anemic group comparing to normal group. The present study reported that majority of pharmacy students in male and female blood donors have low vitamin D levels which represent (87.0%). Out of the total participants (n = 54) who have low vitamin D (n = 49, 79.0%) were classified under vitamin D deficiency category while (n = 05, 08.0%) of students had vitamin D insufficiency. In conclusion, prevalence of hypovitaminosis D (low 25-hydroxyvitamin D) among the pharmacy students at Sebha University was highly occurrence with concomitant a high rate of prevalence of anemia. Thus, vitamin D deficiency at this age represents a public health problem that should be addressed.

University students’ fear of success from the perspective of positive psychology

The aim of this study was to examine university students’ fear of success from the perspective of positive psychology. Two objectives were addressed: first, analyzing the relation between fear of success, optimism, self-esteem, self-efficacy, and search for meaning in life; second, exploring the variance of the fear of success, taking into account the affective dimension of the self (self-esteem) and search for meaning in life. The results confirmed that fear of success was positively related to search for meaning, and negatively to optimism, self-esteem, and self-efficacy. The variance of the fear of success was explained by the self-esteem and search for meaning in life. Implications for school psychologists were discussed.

Risk of pulmonary-reproductive dysfunctions, inflammation and oxidative dna damage in exposure to polycyclic aromatic hydrocarbon in cigarette smokers

Background: Exposure to cigarette smoke has been associated with pulmonary and reproductive dysfunctions; inflammatory response, oxidative stress and oxidative DNA damage induced by polycyclic aromatic hydrocarbons (PAHs) present in cigarette smoke have been implicated in the pathogenesis of these disorders. The peak expiratory flow rate (PEFR), a biomarker of inflammation and oxidative DNA damage (8-hydroxy-2-deoxyguanosine (8-OHdG), tumor necrosis factor alpha (TNF-α)), reproductive hormones (testosterone (TST), luteinizing hormone (LH), follicle stimulating hormone (FSH)) cotinine and urinary PAH metabolite (1- hydroxypyrene (1-HOP)) were estimated in male active smokers. Methods: One hundred men aged 20-47 years, comprising 50 active male smokers and 50 non-smokers, were randomly recruited into this comparative cross-sectional study. The PEFR was measured using a peak flow meter, serum levels of cotinine, FSH, LH, TST, TNF-α, and urine 8-OHdG by enzyme-linked immunosorbent assay and 1-HOP by high-performance liquid chromatography. Data analysis was done using a t-test and correlation analysis at p≤0.05. Results: Smokers had significantly higher cotinine (49.73±31.76 versus 0.51±0.69 ng/ml, p≤0.001), 8-OHdG (16.34±12.10 versus 5.79±2.14 ng/ml, p≤0.001) and lower PEFR (309.20±56.05 versus 452.80±45.76 L/min, p≤0.001) and LH (5.75±2.06 versus 6.97±2.79 mIU/ml, p=0.015) compared to non-smokers. Duration of exposure to cigarette smoke correlated positively with cotinine (r=0.937, p≤0.001) and 1-HOP (r=0.813, p≤0.001) while cotinine correlated positively with 1-HOP (r=0.863, p≤0.001) only in smokers. Conclusion: Reduced lung function and luteinizing hormone and concurrent increase in oxidative DNA damage associated with exposure to cigarette smoke may suggest the involvement of PAH-induced DNA damage in the development of pulmonary and reproductive impairment in smokers.

Security issues in cloud computing and its countermeasures

Cloud computing is a technology of delivering resources such as hardware, software (virtual too) and bandwidth over the network to the consumers worldwide. All the services are requested and accessed through a web browser or web service. The main advantage that cloud is provided to the nation worldwide is that it is not so easily affordable to one and all. Multi-conglomerate companies invest a lot of money on the cloud and let people access it for a smaller cost and even free at the lowest level of the consumer chain. In this paper we address to the problems that the cloud technology faces and how it can be overcome.

Physicians' attitudes, expectations, and experiences about clinical pharmacists and the barriers they have in developing a collaborative relationship with them

The purpose of this study was to determine the attitudes, expectations, experiences, and barriers that physicians in Tripoli hospitals experienced when working alongside Clinical Pharmacists (CPs). A descriptive self-administered questionnaire was used for the study, and participants were selected from several Tripoli hospitals. Most of the respondents agreed that CPs are an essential part of patient care teams and that they have the legal authority to review a patient's medication regimen and response. More than half of respondents believe CPs must be responsible for the medications they prescribe to patients. Half of the respondents agreed that CPs should be encouraged to play a more active role in hospitals and other healthcare facilities. The majority of participants agreed that CPs should participate in managing drug side effects and almost half agreed that CPs can contribute to decisions about drug interactions. By a low agreement rate, 42.7% of respondents thought CPs were specially qualified to counsel patients on drug therapy. A similar low trend was observed, with 40.9% agreeing to provide pharmacists with additional responsibility and authority in clinical departments, in contrast, 54.5% expressed their concern about the clinical responsibility of CPs in clinical practice. A minority of physicians agreed that Physicians should consult pharmacists in selecting the best pharmacological treatment. At the same time, the majority think that pharmacists lack clinical skills and 61.8% feel that physicians are unable to communicate effectively with CPs. 43.6% acknowledged that the traditional opposition between the two professions was a barrier to interprofessional collaboration while the absence of pharmacy space in clinical settings was cited by 39.1%. A majority of respondents agreed that physicians and pharmacists may improve their interprofessional collaboration by raising their awareness about it. A minority of respondents thought that laws and regulations governing physician collaboration should be put in place to promote effective collaboration between physicians and CPs. The study discovered that although most physicians endorse the introduction of clinical pharmacy services in hospitals and believe that physicians and pharmacists can collaborate on many tasks, respondents were not as impressed with the CPs' performance and believed that they lacked the professionalism required to carry out clinical responsibilities successfully. To facilitate the growth of clinical pharmacy services, laws and regulations must be put in place.

Affluent context aware systems based on the user behavior in mobile- pervasive computing environment

A huge number of embedded devices offer their services to the end users in pervasive environments. Context-aware discovery is a rich and very dynamic system extensively applied for combining the different mobile devices, sensors, actuators and software functions. Existing knowledge-based system using the Common KADS (CKADS) system represent contextual information but algorithm are not effective in predicting the user behavior. Current Location-aware Private Service Discovery (LPSD) considers the discovery path for reducing the distributed topology and flooding operations. LPSD in pervasive environment is not effective in accurately locating the required service by searching method. To present an architecture principle for accurately predicting the user behavior in mobile-pervasive computing environment, Affluent Context Aware Systems based on the User Behavior (ACAS-UB) is proposed in this paper. ACAS-UB mechanism contains the class of mobile devices that can sense (i.e.,) search the physical pervasive environment. Affluent means effectively engaged mobile devices in ACAS-UB mechanism which uses the context information. The ACAS-UB context information contains the judgment of the similar users and also the response from the other users for improving the effectiveness in pervasive environment user behavior prediction. Master-slave concept is used in the ACAS-UB mechanism for the easy collection of response information from the different users. ACAS-UB mechanism construct the user profile initially from the context information, then performs the similarity measure and finally work is to predict the user behavior. ACAS-UB mechanism provides the hints which are necessary to explore different options, rather than just limiting the options in mobile-pervasive computing environment. ACASUB mechanism is experimented on the factors such as message overhead in pervasive environment, scalability and approximately 10 % lesser processing time.

Body size dependent rate of oxygen consumption, ammonia excretion and o:n ratio of fresh water bivalve, lamellidens marginalis during summer season.

The study of molluscan animals is called Malacology and the study of molluscan shell is called as conchology. The scaling of metabolic rates with body mass is one of the best known and most studied characteristics of aquatic animals. We studied here how body size is related to rate of oxygen consumption, ammonia excretion and O: N ratio in Freshwater Bivalve Mollusc Lamellidens marginalis species in an attempt to know how body size specific changes affect their metabolism. The freshwater bivalve molluscs with specific body size i.e. small (76-79 mm in shell-length) and large (90-94 mm in shell-length) were chosen for experimental work from Bhima River at Siddhatek on April and May during summer. The adult bivalve molluscs with small body size reported high value in rate of oxygen consumption and O: N ratio but rate of ammonia excretion was low value in small body sized bivalves compared to large ones. The results are discussed in the flush of metabolic processes in fresh-water bivalve molluscs.

Evaluation of student’s perception and attitudes towards switching from in-class to online teaching in the era of covid-19

Worldwide, the focus on online learning during the era of the COVID-19 pandemic faced many challenges. The present study aimed to evaluate the preferences, perceptions, and attitudes of university students toward various strategies of learning. A pre-piloted cross-sectional survey was posted on the internet in Arabic and English language. Questions covered the demographical characteristics of the participants and their preferences and perceptions of various learning strategies. We received 270 questionnaires from various countries. The majority (n=199, 73.7%) of respondents were from the University of Sharjah, United Arab Emirates, with n=125 (46.3%) participants from the College of Pharmacy. The majority (n=198, 73.0%) of respondents were females, Arabs (n=262, 97.0%), living with their families (n=208, 77.0%), and with only the father working (n=174, 64.0%). Preference was, for online learning (n=145, 53.7%) as compared to in-class learning (n=119, 44.1%). More students (n=110, 40.7%) claimed improvement in their grades with online learning but 62 of students (23.0%) stated that their grades were worsened. Student’s performance in online exams was similar to that in paper exams. The majority (n=168, 62.2%) of students claimed that their overall expectations of online learning were not the same as those for in-class learning. 50.0%-60.0% of respondents believed that in-class learning allows them to learn more effectively, and achieve the best work preparation, best exam performance, and best education value, and they were more likely to recommend it. Despite the disadvantages of online learning, it remains the future strategy for higher education. Appropriate planning of courses, and helping students by reducing digital inequity, if any, would certainly prove satisfactory for the millennial generation of students

Antitussive effect of aerial parts of caesalpinia pulcherrima by sulphur dioxide induced cough in rats

Natural products have played an essential role in treating human diseases for thousands of years. According to WHO, 80% of the world’s population relies on traditional medicines to cure and prevent ailments. Numerous plants have been reported to have antitussive activity. Our present study aimed to evaluate the antitussive effect of aerial parts of ethanolic extract of Caesalpinia pulcherrima (Caesalpiniaceae) at 200 and 400 mg/kg doses in healthy albino rats. Caesalpinia pulcherrima is an ornamental plant, usually 3.7-4.3 m in height, known as Peacock flower and is used traditionally to treat cough, bronchitis and asthma. Cough significantly affects human health and is the most common reason to visit physicians. Cough may be produced due to disease, allergens, pollutants and respiratory infections. Any mechanical or inflammatory change provokes the afferent or sensory nerves in the larynx and tracheobronchial, resulting in a cough. In this study, cough was induced by using the sulphur dioxide induction method. Animals were divided into four groups of 7 animals each, and all the drugs were administered orally. Group I was a control group, while group II was a standard taking Prospane. The extract showed highly significant results at 200 and 400 mg/kg doses compared to the control. So, it proves and supports the traditional use of Caesalpinia pulcherrima to relieve cough.
