Experimental and numerical investigation have been done to evaluate the aluminum agglomerate size in AP/HTPB/Aluminum propellants and compared it with burning rate results. Bimodal AP particle size distribution is considered in the present work. The effect of aluminum size, aluminum content, fine AP size, fine AP/binder ratio and coarse AP size in aluminum ignition, accumulation and agglomerate formation during combustion, typically in their ranges, are focused. The burning rates were found to be higher for the propellants with lower fine AP/binder ratio. The agglomerate sizes for the propellants with 10 % Al was found to be higher than those with 15 and 18 % aluminum. Observing the agglomerate sizes and the burning rate trends, it can be concluded that the agglomerate sizes vary inversely as the burning rates.
Vitamin C is associated with history of the cause of the ancient hemorrhagic disease scurvy. Vitamin C is an essential nutrient with important antioxidant properties. It is required by the body for normal physiological function. The body cannot synthesize vitamin C, it is present in nature through foods and other natural sources and it exists as a nutritional food supplement. The antioxidant activity of vitamin C protects the body from free radical damage. Vitamin C is essential for the development and maintenance of connective tissues. It is used as therapeutic agent in many diseases and disorders. Vitamin C plays an important role in several metabolic functions, as the conversion of the amino acid, tryptophan, to the neurotransmitter, serotonin, and the conversion of cholesterol to bile acids. Vitamin C supplementation resulted in a significant increase in vitamin C levels in populations; its high intake is associated with positive effects on cardiovascular risk factors. Vitamin C protects the immune system, reduces the severity of allergic reactions and helps to fight infections. It has an important role in bone formation, wound healing and the maintenance of healthy gums. There is profound beneficial effect of vitamin C in respect to human diseases as cancer, atherosclerosis, diabetes, neurodegenerative disease and many metal toxicities. Several vitamin C analogs have been produced as anticancer and antioxidant activity. Vitamin C is useful if it is used as adjuvant therapy for several chronic diseases. Thus, this review summarizes the importance of vitamin C in the body’s physiology and biochemistry, in addition, the different mechanisms that vitamin C is implicated to treat different acute and chronic diseases. Future exploration should pay attention to chronic disease management by vitamin C.

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 size is related to oxygen consumption, ammonia excretion and O: N ratio in Freshwater Bivalve Mollusc Lamellidens marginalis species in an attempt to know how size specific changes affect their metabolism. The freshwater bivalve molluscs with specific size i.e. small (77 79 mm in shell length) and large (90 93 mm in shell length) were selected for experimental work from Bhima River at Siddhatek on December and January during winter. The adult bivalve molluscs with small size reported high value in oxygen consumption and O: N ratio but ammonia excretion was low value in small sized bivalves compared to large ones. The results are discussed in the glow of metabolic processes in fresh water bivalve molluscs.
Physically unclonable function (PUF) is a hardware security module preferred for hardware feature based random number and secret key generation. Security of a cryptographic system relies on the quality of the challenge-response pair, it is necessary that the key generation mechanism must unpredictable and its response should constant under different operating condition. Metastable state in CMOS latch is undesirable since it response becomes unpredictable, this feature used in this work to generate a unique response. A feedback mechanism is developed which forces the latch into the metastable region; after metastable state, latch settle to high or state depends on circuit internal condition and noise which cannot be predicted. Obtained inter hamming variation for 8 PUF is 51% and average intra hamming distance is 99.76% with supply voltage variation and 96.22% with temperature variation.
In April 2020, Food and Drug Administration (FDA) requested immediate withdrawal of all prescription and over the counter ranitidine products. Ranitidine recalled due to the presence of unacceptable level of carcinogenic substance N-nitosodimethylamine (NDMA). Several pharmaceutical manufacturers have issued ranitidine product recalls including brand and generic ranitidine. FDA alerts patients to stop using ranitidine and advised to talk with their health care professional about alternative treatments. In Libya, limited studies have been conducted to address people awareness and knowledge in this regard. The objective of this study was to assess people's awareness and behavior towards ranitidine recall and related issues. A cross-sectional study was conducted in Zawia city for two months. Online questionnaire was distributed to 300 participants. Descriptive statistics analysis using statistical package for social sciences (SPSS) version 26.0 was used. The study found that more than half of the participants and their family member were likely to utilize ranitidine inappropriately. They seem to consume ranitidine more often without medical consultation. The findings also showed that 82.5% of the participants that were using ranitidine obtained the drug from pharmacies after the date of announcing ranitidine withdrawal from the market by FDA. Furthermore, the vast majority of the participants were poorly informed or even they had no information about ranitidine toxicity and their perception of the dangers of continue use of this drug is limited. The participants argued that pharmacists do not provide slightly information about dispensed ranitidine. In conclusion, all results reported as benefits of the participants in the study whereas the participant's perception and awareness increased when a brief notification regarding the reason of ranitidine toxicity was provided.

Hypertension is a public health issue that significantly increases the risk of health problems and decreases health quality of life of the patients. Angiotensin converting enzyme inhibitors are used to control hypertension by preventing production of angiotensin II in turn decrease blood pressure, thus it may enhance the quality of life. This study aims to assess the effect of angiotensin converting enzyme inhibitors on the quality of life of patients with hypertensive aging 40 years or older in Benghazi city in comparison with other classes of hypertension medications. A case control observational study was conducted, adopting the structured face-to-face interviewing survey technique. Over 150 patients who visited Benghazi medical center during the study period (November, 2019 to March, 2020), to follow up their chronic disease. The investigators used a pre-validated, pre-piloted questionnaire that has been adopted from SF 36 and modified according to the updated literature review; responses to each question were coded and analyzed. The results display that antihypertensive medications were found to be significantly related to the limitation on the physical activity domain and found that medications decrease the limitation on the activity with about 20% of the patients who taking angiotensin receptor blockers (20%) and 30% of the patients taking angiotensin converting enzyme inhibitors, 40% of the patients had no limitations on bending kneeling and stooping. Moreover, on the limitations on walking more than one kilometre, the results were about 15% of the patients taking angiotensin receptor blockers and 30% of the patients taking angiotensin converting enzyme inhibitors had a slightly or no limitation on walking more than a kilometre. Thus, the findings indicate that antihypertensive medications have a positive effect on quality of life of the patient in limitation on activity domain but no conclusive difference was found between angiotensin converting enzyme inhibitors and angiotensin receptor blockers medications.

This paper examines the influence of empowerment on job satisfaction in five-star hotels in Jordan. The influence of empowerment on job satisfaction remains a relatively unexplored area. A 52-item questionnaire, measuring empowerment and job satisfaction, was distributed to 332 employees in 12 five-star hotels in Jordan with a 56% response rate. Principal components analysis determined the factor structure and regression analysis determined the influence of empowerment on job satisfaction. The results revealed both structural and psychological empowerment have significant individual influences on job satisfaction, but more significant when structural and psychological empowerment are combined. Most of previous studies were conducted in western economies and little in the Middle East generally and Jordan in particular. This research contributes to the literature by including both dimensions of empowerment where previous scholars used only one.

Cisplatin, cisplatinum, or cis-diamminedichloroplatinum (II), is a well-known chemotherapeutic drug. It is one of the most widely used chemotherapeutic agents for various solid tumors in the clinic due to its high efficacy and broad spectrum. The antineoplastic activity of cisplatin is mainly due to its ability to cross-link with DNA, thus blocking transcription and replication, Subsequently inducing apoptosis in cancer cells. However, because of drug resistance and numerous undesirable side effects such as severe kidney problems, allergic reactions, decreased immunity to infections, gastrointestinal disorders, hemorrhage, and hearing loss especially in younger patients. Other common side effects include ototoxicity, neurotoxicity, gastrointestinal toxicity, hematological toxicity, cardiotoxicity, and hepatotoxicity. These side effects together reduce the life quality of patients and require lowering the dosage of the drug, even stopping administration, thus weakening the treatment effect Therefore, substantial effort has been made to explore the complicated biochemical processes involved in the toxicology of cisplatin, aiming to identify effective ways to reduce or eradicate its toxicity. This review summarizes and reviews the updated advances in the toxicological research of cisplatin.

The general meaning of a word is the representation of the type from it, in linguistic contexts and certain grammatical forms and this meaning is opposed to the individualized meaning, the separation of a unique item of the type, distinguishable from others. The general meaning seems like a grammatical meaning that is not formally sufficiently marked, but the indefinite articles and the suffixes, in addition to other grammatical meanings, can also express a general meaning in certain contexts. A definite meaning of the noun is generally considered the meaning of the noun in the definite form and indefinite meaning the one of the indefinite noun. But how does the general meaning relate to them? Nouns with general meaning, whether in the indefinite form or in the definite form are meaningfully definite. Both the speaker and the listener know the class that the general noun marks. Despite the formal indefiniteness / definiteness, nouns with a general meaning are semantically definite.
AIM: The present cross-sectional questionnaire survey was conducted to assess the knowledge, and perception related to pharmacovigilance and ADR reporting among the B.pharm Final year students. MATERIALS AND METHODS: To assess the demographic details of the pharmacy students, their knowledge and perception toward pharmacovigilance and ADR reporting; a validated pretested questionnaire was used which comprises 11 knowledge-based closed-ended questions and 14 perceptions based agree/disagree questions. RESULT: The questionnaire was distributed to the 150 respondents of B. Pharm final year students who were willing to participate in the study. A response rate of 75% was recorded. The number of female respondents 53.3% was comparatively higher than the male respondents 46.6%. Most of the respondents were between 20 -22 years of age and only 4.7% were of 25 years of age. The average positive response for the knowledge-related statements was found to be 86.5% and the average positive response for the perception-related statements was found to be 70.67%. CONCLUSION: The findings showed adequate knowledge among pharmacy students and positive perception towards pharmacovigilance and ADRs reporting. This survey strongly suggests that there is a great need for increasing knowledge in clinical pharmacy courses and practical exposure to cases in the hospitals through internship programs which are meant to provide a unique opportunity for the pharmacy students that they must learn and practice the skills required for quality ADR reporting

Despite the evolution of modern technology, the users of hearing aids do not realize the persistence of feedback, while wearing the device until the condition becomes worse. The feedback cancellation algorithms, instead of cancelling the acoustic feedback, limits speech intelligibility. The paper presents a novel method for estimation of SNR based adaptive-feedback equalizers (SBAFE) algorithm to develop an optimized hearing aid for the feedback less sound transmission and achieving better speech discrimination. The data gathered for the optimization is visualized and compared with the traditional technology, which provides the subjective and objective quality of the hearing aids.
Schizophrenia is treated with antipsychotic drugs and is a chronic neuropsychiatric disorders. The influence of antipsychotics on the cytokine systems may be responsible for their clinical efficacy in schizophrenia. Granulocytopenia and agranulocytosis are severe side effects of antipsychotic therapy. The objective of this study was to estimate incidence of drug-associated agranulocytosis in newly diagnosed schizophrenic patients in and to evaluate the risk factors and outcomes. Seven participants groups were designed. Healthy persons as control. Schizophrenic patients before treatment. Schizophrenic patients after one-month of treatment. Schizophrenic patients after two - month of treatment. Schizophrenic patients after three - month of treatment. Schizophrenic patients after chronic treatments. Schizophrenic patients one month after chronic treatment. This study included screening for the expression and function of circulating leukocyte granulocyte-macrophage colony-stimulating factor receptor, screening of patient's biochemistry and haematology picture. Granulocyte-macrophage colony-stimulating factor expression was decreased after antipsychotic treatment for one month and continued to decrease after two months' treatment. Granulocyte-macrophage colony-stimulating factor expression starts to increase after the two-month treatment and continues increasing to controls or newly diagnosed schizophrenics or after chronic treatment. Complete blood counts were not changed compared. Liver function showed a transient increase in serum alkaline phosphatase after one and two month of treatment. All other parameters were not changed. Kidney function showed that urea and creatinine levels were within the normal range during the different treatments. Concerning lipid profile, low density lipoproteins levels were increased after one month, two months of treatment and after chronic administration of the antipsychotic drugs. It is concluded that antipsychotic treatment produces a decrease in granulocyte-macrophage colony-stimulating factor expression; the decrease reach the maximum effect after two months, then starts to increase back to normal levels. A transient increase in serum alkaline phosphatase in the first two months' treatment. Urea and creatinine levels and lipid profile were within normal range, except low density lipoproteins levels were increased during the two months treatment and after chronic administration of the antipsychotic drugs.

Pelvic inϑlammatory disease (Waram al-Rahim)is one of the most serious gynaecological infections of the upper female genital tract with the worldwide annual rate of 10-20/1000 women of reproductive age. The objective planned for the study was to evaluate the effect of Sharbat-e-Deenar in uncomplicated Pelvic Inϑlammatory Disease (uPID). A pre and post observational single group clinical study was carried out in the Department of IlmulQabalatwaAmrazeNiswan, National Institute of Unani Medicine, Hospital, Bengaluru. Diagnosed cases (n=30) of uPID were included in the study. Patients with complicated PID, history of antibiotic therapy within seven days of recruitment; delivery, abortion or gynecologic surgery within the last 30 days, systemic diseases, malignancies, pregnancy & lactation were excluded. Sharbate-Deenarconsists of Poste baikhekasniandTukhmekasni(Cichorium intybus Linn.), Gulesurkh (Rosa damascene mill.), Tukhmekasoos(CuscutarelexaRoxb.) and Rewandchini (Rheum emodiWall. ex Meissn) were administered orally in a dose of 20 ml twice daily for 14 days. Outcome measures were 30-70% clinical improvement in Visual Analogue Scale (VAS) score for lower abdominal pain and McCormack Pain Scale (McPS) score for abdominopelvic tenderness and White Blood Cells (WBCs) count <10 on saline microscopy of discharge. Data were analyzed using paired Student ‘t’ test, Wilcoxon Signed rank test and Paired Proportion test.Clinical improvement of 30-70% in McPS and VAS score was achieved in 96.7% (p<0.001**) and 93.3% (p<0.001**) patients respectively. WBCs count <10 on saline microscopy of discharge was achieved in 70% patients (p<0.001**).Sharbat-e-Deenarwas effective in improving the sign & symptoms of PID due to its anti-microbial, anti-inϑlammatory, antispasmodic and anti-oxidant properties. No adverse effect of the research drug was encountered during the study. Hence, Sharbat-e-Deenar serves as an effective alternative in patients with PID, proving the research hypothesis.
