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.
This study ascertained availability of disaster preparedness and digitization in archives preservation in public libraries in Rivers state. Two objectives and its corresponding research questions and hypotheses guided this study. The descriptive survey design was adopted for this study. The target population of this study comprised 514 library staff drawn from Rivers state library board and staff from Jubilee library Port Harcourt. The sample size for this study was 399 library staff comprising of 227 staff from Rivers state library board and 172 library staff from Jubilee library Port Harcourt. The sample size was determined by Taro Yamane sample size determination formula while a two-stage sampling technique of stratified and simple random sampling techniques was used to select the sample size. A self-structured questionnaire titled availability of disaster preparedness and digitization in archives preservation questionnaire was used as the instrument for data collection. Face and content validation was ensured by three experts. The instrument yielded reliability coefficients of 0.79 with the use of Cronbach Alpha reliability method. Meanand Standard Deviation was used in answering research questions while z-test was used for the inferential statistics. The findings revealed that disaster preparedness and digitization in the preservation of archives are supported and available in public libraries in Rivers state, Nigeria. Based on the findings, it can be concluded that there are significant differences in the responses of Rivers state library board staff and Jubilee library Port Harcourt staff on the terms of the availability of the disaster preparedness and digitization in archive preservation in the public libraries. It was therefore recommended that more librarians should be employed by the Rivers state government so as to make the process of archive preservation in the State’s public libraries through disaster preparedness and digitization less rigorous and efficient.
Before the start of the SARS-CoV-2 (COVID-19) pandemic, the whole environment around us had been deemed very toxic to breathe in due to the amount of greenhouse gases that had been emitted over the centuries. The Earth faced rising temperatures, which in turn led to the melting of glaciers and rising of sea levels. Environmental degradation was happening fast due to the depletion of resources such as air, water and soil. But after the coronavirus lockdown (Talabandi) commenced, there have been changes in the environment. The lockdown still has a huge impact on people in India too. The halt of industrial production and traffic resulted in cleaner air and rivers. In India the first phase of the nationwide lockdown that began on March 24 followed by enforcement of a series of regulations had some evidences that the COVID-19 curve is flattening in the country's COVID-19 affected regions. There was a good chance Prime Minister Narendra Modi extended the lockdown (Talabandi) four times that ended on (Phase 1 (24 March-14 April)., Phase 2 (15 April-3 May)., Phase 3 (4 May-17 May) & Phase 4 (18 May-31 May). The paper focuses on different aspects of environmental impact due to SARS-CoV-2 in India.

Recently, wireless sensor networks (WSNs) have been deployed for a wide variety of applications, including military sensing and tracking, patient status monitoring, traffic flow monitoring, where sensory devices often move between different locations. Securing data and communications requires suitable encryption key protocols. In this paper, we propose a certificateless-effective key management (CL-EKM) protocol for secure communication in dynamic WSNs characterized by node mobility. The CL-EKM supports efficient key updates when a node leaves or joins a cluster and ensures forward and backward key secrecy. The protocol also supports efficient key revocation for compromised nodes and minimizes the impact of a node compromise on the security of other communication links. A security analysis of our scheme shows that our protocol is effective in defending against various attacks.We implement CL-EKM in Contiki OS and simulate it using Cooja simulator to assess its time, energy, communication, and memory performance.

Abstract- The role of support vector machine in the evaluation of English teaching effect is very important, but there is a problem of inaccurate evaluation of results. The traditional English teaching mode cannot solve the accuracy and efficiency of the effect evaluation of students' English teaching and cannot meet the requirements of English teaching effect evaluation. Therefore, this paper proposes a neural network algorithm to innovate and optimize the analysis of support vector machines. Firstly, the relevant theories are used to construct a multi-index English teaching effect evaluation system with teachers and students as the main body, and the indicators are divided according to the data requirements of English teaching effect evaluation indicators to reduce the support vector machine in the interfering factor. Then, the neural network algorithm is used to solve the optimal solution of kernel function parameters and regularization parameters of the support vector machine, and the support vector machine scheme is formed, and the support vector machine results are carried out Comprehensive analysis. MATLAB simulation shows that the evaluation accuracy of the English teaching effect of the neural network algorithm and the support vector machine under certain evaluation criteria Optimal, short evaluation time.
Capsicum has been an essential part of the diet for centuries and has been widely used traditionally for ailments. The objective of the present analysis was to determine the diuretic and antidiarrheal potentials of four variations of Capsicum annum L. fruits available in the local market of Karachi, Pakistan. It belongs to the family Solanaceae, and extracts were prepared in 95% ethanol and given in 200 and 400mg/kg doses. The activity correlated with commonly used diuretics and anti-diarrheal, reinforcing its conventional use. To confirm its activity, fruit extracts were evaluated for anti-diarrheal properties in castor-oil-induced diarrhoea. The diuretic activity of the 95% ethanolic extracts of Capsicum annum L. was assessed based on diuresis of 24 hr. collected through a metabolic cage. Urinary excretion of water and electrolytes (Na+ and K+) is significantly increased by the standard diuretic drug furosemide, which is comparable with the extract. The anti-diarrheal effects of 95% ethanolic extracts of Capsicum annum L. were examined by castor oil-induced diarrhoea. All varieties of Capsicum annum L. significantly inhibited the number of defecations.
The aim of the study is to: assess the effectiveness of structured teaching programme on prevention of selected postoperative complications among 300 patients undergoing abdominal surgeries in selected hospitals. A pre-experimental research design and convenient sampling technique was adopted study. Data were collected by using structured interview schedule and structured questionnaire was used to assess the existing knowledge regarding prevention of selected post operative complications. Shows that majority (42.70%) subjects had inadequate knowledge and (18.30%) had moderate knowledge in pre test. In post test majority 44 (73.3%) had adequate knowledge and 16 (26.7) had moderate knowledge. The pre test mean score was 16.15 with the standard deviation of 4.65, whereas in post test the mean score was 30.7 with the standard deviation of 5.387 which indicates that structured teaching programme is statistically significant at P<0.01 level. There was significant difference between the pre test and post test knowledge scores t=20.56, P<0.01 level. There was a significant association between pre test knowledge scores with their education and no association between age, gender, religion, occupation, marital status, type of family, place of domicile, dietary pattern, personal habits and source of health information at P<0.01 level. Author concluded that that post test knowledge scores was improved after structured teaching programme. So structured teaching programme was effective in increasing the knowledge level regarding prevention on selected post operative complications among patients undergoing abdominal surgeries.
Lytic lesions in adult spine are a common manifestation of aggressive disease such as primary bone tumor, metastasis, myeloma, or infectious pathology. Xanthoma arising in the spine with purely intraosseous component is an extremely rare occurrence with only six cases reported in the adult population, none in the cervical region. We report the first case of primary xanthoma of the cervical spine in a 50‑year‑old male solely confined to osseous compartment. The imaging mimics of lytic lesion with expansile mass in adult spine are reiterated.
Objective As technology continues to improve, it plays an increasingly vital role in the practice of medicine. This study aimed to assess the feasibility of the implementation of virtual reality (VR) in a rheumatology clinic as a platform to administer guided meditation and biofeedback as a means of reducing chronic pain. Methods Twenty participants were recruited from a rheumatology clinic. These participants included adults with physician-diagnosed autoimmune disorders who were on a stable regimen of medication and had a score of at least 5 on the pain Visual Analog Scale (VAS) for a minimum of 4 days during the prior 30 days. VAS, part of most composite outcome measurements in rheumatology, is an instrument used to assess pain that consists of a straight line with the endpoints ranging from “no pain at all” and “pain as bad as it could be.” Patients were randomized into two groups that differed in the order in which they experienced the two VR modules. One module consisted of a guided meditation (GM) environment, whereas the other module consisted of a respiratory biofeedback (BFD) environment. Data on pain and anxiety levels were gathered before, during, and after the two modules. Results The three most common diagnoses among participants were rheumatoid arthiritis (RA), lupus, and fibromyalgia. There was a significant reduction in VAS scores after BFD and GM (P values = 0.01 and 0.04, respectively). There was a significant reduction in Facial Anxiety Scale after the GM compared with the BFD (P values = 0.02 and 0.08, respectively). Conclusion This novel study demonstrated that VR could be a feasible solution for the management of pain and anxiety in rheumatology patients. Further trials with varying treatment exposures and durations are required to solidify the viability of VR as a treatment option in rheumatology clinics
This study was conducted to optimize the integration of solar-photovoltaic-distributed energy resources (SPVDERs) within the Nigerian power system networks using an AI-based Particle Swarm Optimization (PSO) Algorithm. By employing a mixed research method, primary and secondary data were gathered to calculate flow analysis, NR method's equations, PSO's position update model, particle swarm optimizer algorithm, and application modeling including Solar-PV DER modeling. The AI-based PSO algorithm design was developed for optimizing SPV-DER integration in Nigerian power system networks, and key parameters and variables that needed consideration were identified. The study also established how the performance of the AI-based PSO algorithm could be evaluated and compared with other optimization techniques for SPV-DER integration within Nigerian power system networks. The study's results showed that voltage limits were within acceptable ranges, and solar power contributions were estimated at 880.10MW with 46,718 panels needed. The study concluded and recommended that investing in AI-powered tools for efficient power distribution; monitoring and resource optimization for sustainable energy sources would optimize performance and unleash Nigeria's sustainable energy potential.
Nowadays, the Internet of Things (IoT) has been used widely in our daily day to day life, starting from health care devices, hospital management appliances to a smart city. Most of the IoT devices have limited resources and limited storing capability. All the sensed information must have to be transmitted and to store in the cloud. To make a decision and for making analysis all the data stored in the cloud has to be retrieved. Making certain the credibility and security of the sensed information are much necessary and very important for the use of IoT devices. We tend to examine the proposed technique to be much secure than the existing one. In IoT, if the security is not ensured, then it may result in a variety of unsought issues. This survey resembles the overall safety aspects of IoT and debates the overall issues in the security of IoT.
In this intelligent transportation systems era, traffic congestion analysis in terms of vehicle detection followed by tracking their speed is gaining tremendous attention due to its complicated intrinsic ingredients. Specifically, in the existing literature, vehicle detection on highway roads are studied extensively while, to the best of our knowledge the identification and tracking of heavy-construction vehicles such as rollers are not yet fully explored. More specifically, heavy- construction vehicles such as road rollers, trenchers and bulldozers significantly aggravate the congestion in urban roads during peak hours because of their deadly slow movement rates accompanied by their occupation of majority of road portions. Due to these reasons, promising frameworks are very much important, which can identify the heavy-construction vehicles moving in urban traffic-prone roads so that appropriate congestion evaluation strategies can be adopted to monitor traffic situations. To solve these issues, this article proposes a new deep-learning based detection framework, which employs Single Shot Detector (SSD)-based object detection system consisting of CNNs. The experimental evaluations extensively carried out on three different datasets including the benchmark ones MIO-TCD localization dataset, clearly demonstrate the enhanced performance of the proposed detection framework in terms of confidence scores and time efficiency when compared to the existing techniques.

One must accept the complexity of modern society as a multifaceted influence which will direct the future of all social organizations. Technology has brought the people of the world into almost instant communication. Biomedical science has conquered most infectious, acute diseases and has provided several medicines for a successful maintenance therapy of chronic diseases. The life style of some people as smoking and drug addiction remain a strong factor to their achievement of health goals of the good life. Universally, economic inflation and international business have created an economic interdependence among nations and dealing of the economic problems of one country must take into account this interdependence. When one views the future within this technologic-social-economic framework, he has difficulty sorting out certain directing influences that may shape the future of pharmacy practice in Libya. Currently, the duties, functions and roles undertaken by pharmacists in Libya range from those limited to traditional dispensing duties to highly clinically oriented roles [1]. In this regard, the Libyan health service providers request for the expanded roles of pharmacists in the society. Many of them ask for a number of clinical and patient-oriented functions as oncology, patient counseling, chronic care, hypertension, pediatric, diabetes, psychiatric, cardiology and others. They also question for protocols, standing orders and procedures for pharmacist management of drug therapy and provide information to use as a basis for initiation of clinically oriented services. The treatment of chronic diseases will be refined and drug therapy in many instances will be improved through the application of pharmacokinetic principles and improved methods of monitoring. There is no doubt that pharmacy practice has made clear steps in its own professionalization in hospitals during the past years. With an increase in the number of pharmacists practicing in hospitals and drug stores has come other changes in pharmacy manpower. Technicians and assistant pharmacists now perform many of the routine tasks in drug distribution under pharmacist's supervision. The latter, therefore, is available to participate in clinical programs in inpatient areas and in outpatient clinics. The practice of technicians and assistant pharmacists both in and out of hospitals remains a controversial issue in Libya (absence of a clear national medical policy). Many pharmacists in Libya who provide services hold Bachelor degree in Pharmacy or Pharmaceutical Sciences or Doctor of Pharmacy (Pharm D) or have completed a short or long term diploma training in teaching hospitals or postgraduate academics. Some hold appointments in other health professions institutions. Libyan Association for Pharmacists (LAP) and Libyan Medical Board are currently planning for a program in clinical pharmacy in different clinical branches. Nevertheless, professional pharmacy personnel must be upgraded in the future in both educational background and competence if continued professionalization is to be achieved [2]. The future will see continued stratification of professional personnel according to specialized functions in management and clinical and other professional; services particularly in large hospitals. The scope of the educational function of pharmacy will expand and become an increasingly important activity in the future in Libya. Some hospitals will maintain health education facilities as part of their physical plant. Others will participate in the program of area health education centers. Pharmacy's responsibility in this effort will require not only an increased commitment, but likewise, increased capability and capacity to provide educational services.

Background: Breast cancer is a commonly found malignancy worldwide in women, and effective treatment is regarded as a substantial clinical challenge even in the presence of several options. Extensive literature is available that demonstrates polyphenols, the richly introduced phytopharmaceuticals, as anticancer agents. Among these polyphenols, resveratrol, silibinin, quercetin, genistein, and curcumin are reported to have tremendous potential against breast cancer. However, till now, no comprehensive survey has been found about the anticarcinogenic properties of luteolin against breast cancer. Scope and approach: This review targeted the available literature on luteolin in the treatment of breast cancer, its effects in combination with other anticancer drugs, and possible mechanisms. Key findings and conclusion: Lutein's outstanding therapeutic potential in the treatment of breast cancer has been recorded not just as a chemopreventive and chemotherapeutic agent but also complemented by its synergistic effects with other anti-cancer therapies such as cyclophosphamide, doxorubicin, and NSAIDs such as celecoxib and possible underlying mechanisms. Ideally, this review will open new dimensions for luteolin as an effective and safe therapeutic agent in diminishing breast cancer.
The study identified the pragmatic competence level of the second language (L2) learners through Written Discourse Completion Test (WDCT) administered to purposively selected 40 first-year education students. A modified questionnaire based on Survey for Academic English Language Exposure (SAELE) was used to determine the effectiveness of academic English language exposure on the pragmatic competence development of the respondents. The study employed the descriptive-correlational method, while various statistical tools were utilized to analyze and interpret the data. Weighted mean was used to determine the respondents’ pragmatic competence level and the effectiveness of academic English language exposure on the pragmatic competence development of the respondents. Moreover, Pearson Product Moment Correlation (PPMC) was employed to determine the significant relationship between the two variables. Results in WDCT showed that the average scores in the pre-test and post-test results fall under the competent level. Meanwhile, the effectiveness of academic English language exposure on the pragmatic competence development of the respondents was 0.207, which is ineffective. Lastly, the statistical correlation of the two variables showed no significant relationship between them (r=0.046, p>0.05). Based on the study’s results, pedagogical implications for pragmatic and L2 teaching and learning were conceptualized.
Cet article porte sur l’ouvrage Le ventre, le pain ou la cendre de Tchicaya U Tam’si. À partir des approches linguistique, stylistique et sémiotique, nous avons tenté de montrer, dans notre analyse, en quoi l’écriture de ce recueil construit des stratégies discursives propres à retenir l’attention du récepteur. À cet effet, nous avons relevé deux principales figures de rhétoriques à savoir, l’emphase et l’hyperbole. Ces deux procédés de style produisent d’une part un effet d’insistance du procès poétique ; et de l’autre, un effet d’amplification du langage poétique.
