Ever-growing era of mobile and personal wireless networks, motivated research in several fields of engineering resulted in low power and low cost consumer products. The voice band processing required in mobile applications demand for architectures, which can easily be integrated in single chip SoC applications. The conventional approach is to have a dedicated IC outside the digital ICs to perform analog to digital conversion. The motivation of single chip radios demand for integration of such ADC modules on digital cellular related ICs. Mixed signal design is very challenging and hence usually it is preferred to have separate ADC chip before the ASIC/FPGA. In this paper we present a digital sigma delta ADC architecture, which can perfectly be integrated in any digital IC with a targeted sampling rate of 20 kS/s with more than 80 dB dynamic range.
Ageing is an inevitable phenomenon. Similar to other organs, skin is also subject to an intrinsic ageing process. Additionally, skin ageing is also influenced by various environmental factors. Existing conventional formulations have limited efficacy because skin serves as a rate limiting barrier for percutaneous absorption of drugs. This has led to the evolution of various novel drug delivery systems. Among these liposomes have received considerable attention due to the numerous advantages they offer. Liposomes, submicroscopic spherical vesicles, were discovered in 1960’s. Since then, they have gained popularity as potential carriers for drugs, diagnostics, nutrients, vaccines and other bioactive agents. Liposomes find applications in pharmaceutical, cosmetics and other industrial fields. Various topical actives that have been found to be efficacious in delaying the signs of ageing have been formulated as liposomes resulting in enhanced delivery, biocompatibility, and reduced toxicity. This review focusses on therapeutic use of liposomes in skin ageing.
Paracetamol is one of the most found over the counter drugs worldwide. It is widely used as an analgesic and antipyretic drug. Many commercial types of paracetamol tablets are available under different brand names in the Libyan drug market. The present study was conducted to evaluate post-marketing quality parameters for three brands of paracetamol tablets marketed in Libya. All three brands were evaluated for weight variation, hardness, friability, disintegration time and uniformity of content following British pharmacopeia guidelines. The outcomes of this study showed all tested brands complied with the British pharmacopeia specifications for the weight variation test, friability test (0.05%-0.17%), and hardness test (171.3N-197.6 N). In addition, two brands passed the British pharmacopeia requirements for the disintegration time test, whereas one brand exceeded the allowed disintegration time by about five minutes. Furthermore, high performance liquid chromatography was used to determine paracetamol content. Although the average amount of paracetamol drug available in these brands is not very close to 100%, where one brand achieved the lowest value (438.1 mg), the loaded dose of paracetamol in selected tablets in the three brands was within the British pharmacopeia standard specifications for the uniformity content test. Therefore, it can be concluded that almost all the three tested brands of paracetamol tablets that are available in the Libyan drug market meet the British pharmacopeia specification for quality control analysis.

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.

Effective crisis communication response through using the proper strategies is critical to cope with crises and to protect the reputation and existence of the involved parties. Usually, aviation accidents receive great attention from the media and the public. Malaysia Airlines Flight 17 (MH17) which was shot down over eastern Ukraine on 17 July 2014 during its scheduled flight from Amsterdam to Kuala Lumpur received global attention. This attention was due to the involvement of several countries either at the level of the countries of victims or the countries accused of the attack. Image repair theory proposed by William Benoit, the widely used in crisis communication response was implemented in this study. The Russian response to the international accusation, especially from the Western world on supporting the attackers of MH17 has been examined in this study. This study implemented both quantitative and qualitative content analysis to achieve its aims. A total of 306 news stories from the online New Straits Times newspaper Website from the years 2014 to 2019 were analysed. A total of 191 strategies were included in 123 news stories since some stories combined more than a strategy. Out of 191 strategies, 43.5% were simple denial, followed by shift the blame and attack accuser with 35.1% and 21.5% respectively. The results revealed that the image repair effort by Russia was effective and successful.
s deep learning models continue to grow in complexity, the computational and energy demands associated with their training and deployment are becomingincreasingly significant, particularly for convolutional neural networks (CNNs) deployed on CPU-bound and resource- limited devices. Fully connected (FC)layers, while vital, are energy-intensive, accounting for 85.7% of a network’s parameters but contributing only 1% of the computations. This research proposes anovel approach to optimising these layers for greater energy efficiency by integrating low-rank factorisation with differential partial differential equations (PDEs).The introduction of the LowRankDense layer, which combines low-rank matrix factorisation with a differential PDE solver, aims to reduce both the parametercount and energy consumption of FC layers. Experiments conducted on the MNIST, Fashion MNIST, and CIFAR-10 datasets demonstrate the effectiveness ofthis approach, yielding promising results in terms of reduced energy usage and maintaining comparable performance, thereby enhancing the practicality andsustainability of CNNs for widespread use in environments with limited computational resources
Saline and sodic (alkali) soils can significantly reduce the value and productivity of affected land. By estimation, slightly more than one-fourth of irrigated farmland in the United States is affected by soil salinity. Ions most commonly associated with soil salinity include the anions chloride (Cl–), sulfate (SO4=), carbonate (HCO3–), and sometimes nitrate (NO3–) and the cations sodium (Na+), calcium (Ca++), magnesium (Mg++), and sometimes potassium (K+). Crops differ in ability to tolerate salt accumulation in soils, but if levels are high enough (more than 16 mS/cm), only tolerant plants will survive. As salts accumulate in soil, the soil solution osmotic pressure increases. Reclamation of sodic soils is different; excess sodium must first be replaced by another cation and then leached. Sodic soils are treated by replacing the sodium with calcium from a soluble source.
Malignant melanoma is the most dangerous type of skin cancer. It is becoming more common globally and is increasingly resistant to treatment options. Despite extensive research into its pathophysiology, there are still no proven cures for metastatic melanoma. Unfortunately, current treatments are frequently ineffective, costly, and have several adverse effects. Natural substances have been extensively researched for their anti-MM capabilities. Chemoprevention and adjuvant therapy with natural products is an emerging strategy to prevent, cure or treat melanoma. Numerous prospective drugs are found in aquatic species, providing a plentiful supply of lead cytotoxic chemicals for cancer treatment. Anticancer peptides are less harmful to healthy cells and cure cancer through several methods, such as altered cell viability, apoptosis, angiogenesis/metastasis suppression, microtubule balance disturbances and targeting lipid composition of the cancer cell membrane. This review addresses marine peptides as effective and safe treatments for MM and details their molecular mechanisms of action.

Tesco avails different personal banking packages (services and products) that include personal loans, personal current accounts, and credit card receivables. Tesco's businesses are therefore Tesco Hungary, Tesco UK, Tesco Czech Republic, Tesco Slovakia, Tesco Ireland, Dunnhumby, and Tesco Bank.
Elevated arterial blood pressure is the most important public health problem in developed countries. It often leads to lethal complications if left untreated. Brewer's yeast is celebrated for its various beneficial effects, including a possible hypotensive effect. Thus, the anti-hypertensive effects of brewer’s yeast were investigated. The hypertensive model was done by a once-weekly intraperitoneal injection of dexamethasone at a dose of 25 mg/kg combined with drinking a 1.0% sodium chloride solution containing 0.2% KCl and 2.0% glucose for six weeks. The blood pressure was measured by the rat carotid artery cannulation preparation. Different doses of brewer's yeast dissolved in distilled water were injected into the internal jugular vein, with measurement of blood pressure at each time. To explore the mechanism of the hypotensive effect of yeast, the yeast cardiac effect was verified by the use of isolated perfused rabbit heart preparations using different antagonists. It was found that dexamethasone elevated systolic blood pressure to 178.3±11.6 and diastolic blood pressure to 133.3±16.6 from normal levels of 115.0±9.1 for systolic and 74.0±4.1 for diastolic. The gradual increase in intravenous yeast doses ranging from 0.05 to 0.40 effectively lowered systolic and diastolic blood pressure in rats with normal pressure, bringing them to approximately 80.0±05.6 mmHg for systolic and 40.0±3.5 mmHg for diastolic. While doses exceeding 0.04 resulted in a drop in systolic pressure to 60.0±3.9 mmHg, diastolic pressure became unrecordable. The administration of the 0.20 dose resulted in unrecordable blood pressure. In hypertensive rats, a decrease in blood pressure was observed with doses ranging from 0.60-1.0 mg, leading to a reduction to 110.0±2.8 mmHg for systolic and 52.0±9.9 mmHg for diastolic pressures. Doses exceeding 1.0 mg further lowered systolic and diastolic pressures to 20.0±3.9 mmHg. There was a mild increase in heart rate with no change in cardiac force of contraction. This effect was not mediated through beta, calcium receptors, or the histamine effect. The findings show that the yeast has a dose-dependent blood pressure-lowering effect. The mechanism of the chronotropic effect is possibly due to its direct action.

Background: In a Benghazi medical center, this observational study assessed the role of laparoscopic cholecystectomy (LC) in the early stages of acute gallbladder illness. Materials and Methods: From January 2022 to December 2022, all emergency and urgent admissions for acute gallbladder disease were identified, and additionally, data from hospital medical records were then evaluated retrospectively. Results: Out of a total of 334 patients with gallstone diseases, we found 321 individuals (206 with acute biliary colic, 115 with acute calculous cholecystitis), and 13 with acalculous cholecystitis. Early laparoscopic surgery for acute calculous cholecystitis had a greater conversion rate than procedures for acute biliary discomfort (19% vs. 4%; p=0.002). When surgery was performed 72 h from the onset of the symptoms for patients with acute calculous cholecystitis, the conversion rate was considerably lower (one out of 25) than when surgery was postponed past 72 h (14 out of 53) or later performed electively (seven out of 23) (p=0.014). In comparison to elective surgery for acute biliary colic (three of 66), elective surgery for prior acute cholecystitis was linked to a higher conversion rate (seven of 22 patients) (p=0.002). Conclusion: LC for acute calculous cholecystitis needs to be done within 72 h of the onset of symptoms, and it is worthwhile.
The cross line movement according to the two labor and products is the thing to take care of in the present worldwide economy. Worldwide exchange labor and products has for some time been a standard, for different advantages that gather from it. There have been numerous respective and multilateral arrangements comparable to cross line exchange dealings. The development of administrations area that decidedly influences the everyday daily routine and guidelines of experiencing or personal satisfaction. The World Trade Organization (WTO), of which in excess of 156 nations are individuals, has an understanding according to global administrations exchange. The General Agreement on Trade in Services (GATS) is the WTO's arrangement that administers exchange 12 sorts of administrations, including 'instruction administrations'. One of the basic inquiries or issues in such manner would be corresponding to the sort of college to be permitted to set up its grounds or branch or in any case offer training administrations. This paper would endeavor to give some potential experiences into this issue. Internationalization and globalization are the two Global ideas terms conversely utilized as far as higher education. Most impressively, the test to set up colleges will come from the worldwide monsters of the interchanges, data innovation and mixed media ventures worldwide suppliers, packed with capital, ready to get to remarkable global researchers and educators, talented in giving in situ understudy support at the same time in numerous nations, and equipped for expediting proficient accreditation and acknowledgment all throughout the planet. Quality in the subsequent 'worldwide virtual colleges' will be high, normalization will make cost structures that are powerfully serious, brand acknowledgment will be acquired, maybe by accepting one of the incomparable Ivy League organizations as an accomplice, or on the other hand by moving into advanced education a prevailing brand from the correspondences or processing ventures.
The study employed Appreciative Inquiry framework to have an in-depth investigation in the personal lives of the participants and to draw connections between their beliefs and practices in taking Licensure Examination for Teachers and how these superstitions reflect and affect their moral principles. Specifically, it aimed to: (1) determine the superstitious beliefs followed by the examinees before, during, and after taking the Licensure Examination for Teachers (LET); (2) determine the positive and negative impact of these superstitions in the aspect of taking LET; and, (3) identify the effects of these superstitions in the characters and principles of the teachers. Semi-structured interview and focus group discussion were used and the data-sources were triangulated to come-up with a stronger analysis. Audit trail and member checking were followed to ensure that there were no biases in the interpretation of the data and to establish the validity of the results. Findings revealed that the student examinees followed different superstitious beliefs before, during and after the exam which have positive and negative effects. The motive of avoiding failure in the examination predominates over the motive of achieving success. The positive and negative effects of superstitions vary from one person's experience to another. Moreover, the assertion and personal disposition to pass the exam became the product of student examinees' projection. The superstitious notions were initiated to discard the student examinees' fears and to safeguard their emotional sphere against negative feelings and any untoward possibilities. Meanwhile, in the development of moral principle, the student examinees' family, peers and the society are important factors in the establishment of their belief system which later on reflects the moral principles they uphold.
Background: The significance of healthcare wastes (HCWs) consists in their hazardous component, which constitutes real danger to public health. In Nigeria, healthcare waste management (HCWM) has remained a problem yet to be properly recognized and so addressed. The study aimed to sensitise health workers and the public on the need for proper management of HCWs, considering the public health implications of not doing so. Methods: The waste management systems of ten healthcare facilities (HCFs) were assessed, using a modification of the WHO rapid assessment tool. In each HCF, segregated wastes were collected daily for ten days and quantified by weighing, using a spring balance. Results: Administratively, the HCWM system was poor in the ten HCFs (40.6%). 70% of them had satisfactory waste segregation, 81%, good waste treatment, and 26.7% adequate transportation methods for waste. None of the HCFs had budget allocation for HCWM, and 90% had inadequate storage facilities. Mean waste generation was 1.81 kg/day, 0.23 kg/patient/day, 0.16 kg/bed/day, and proportion of infectious wastes 16.8%. Correlation between the number of patients and proportion of infectious waste, was positive, strong and significant (r=0.80, p=0.01), and between bed occupancy rate and proportion of infectious waste, was positive too, but weak, and insignificant (r=0.34, p=0.34). Conclusions: In view of the identified weaknesses of the ten HCFs in HCWM, budget allocations for HCWM, improving waste storage facilities and transportation, with strengthening of waste segregation, collection, and treatment, would help to ensure adequate HCWM in the HCFs.
Background and Objective: Health care workers (HCWs) are at the highest risk of contracting COVID-19, so their knowledge about the disease and their preventive attitude and practice toward COVID-19 are of concern. The present study aimed to assess the knowledge, attitudes, and practices of HCWs toward COVID-19 in Al-Thawra Hospital, Ibb Governorate, Yemen. Materials and Methods: We conducted a cross-sectional survey among HCWs in Al-Thawra Hospital, Ibb, Yemen, from January 1 to March 31, 2022. Results: Of the 80 participants, 50 (62.5%) were males and 30 (37.5%) were females with a mean age of 29.33±7.86 years. About 51.2% of respondents were aware that sneezing is a recognized symptom of COVID-19, while most were unaware of the extrarespiratory symptoms of the disease, such as diarrhea and confusion. About 28.7% of respondents believed that eating or contacting wild animals would result in infection by the COVID-19 virus, with the majority (71.3%) agreeing that wearing a well-fitting face mask effectively prevents COVID-19 infection. Approximately 48 respondents (60.0%) believed that washing hands could prevent contracting COVID-19, and only 31 (38.7%) agreed that if a patient shows signs and symptoms of COVID-19, they can confidently participate in that patient’s treatment. In response to avoid COVID-19, about 23 respondents (28.7%) had always gone to crowded places, and 35 (43.6%) had always worn face masks at every contact with patients, while only 14 (17.5%) of participants refrained from shaking hands and 37 (46.3%) always washed their hands before and after handling each patient. Conclusion: This study showed that most respondents have poor knowledge regarding the clinical picture of COVID-19 and its mode of transmission as most of them failed to detect an extrapulmonary manifestation of COVID-19 and were unaware of the possibility of transmission of the disease from wildlife. In addition, the attitude and preventive practice of the respondents were unsatisfactory in containing the transmission of the disease.

Trace elements are minerals present in living tissues in small amounts. Some of them are known to be nutritionally essential, others may be essential, and the remainder are considered to be nonessential. Trace elements such as zinc, copper, selenium, iron, chromium and, others are essential elements for growth and body health. They form an integral part of many enzymes and bioactive centers that are responsible for biochemical reactions such as metabolism, protein and, DNA synthesis. They are said to contribute to the development of cancer based on epidemiologic evidence. The blood level of trace elements in the human body is affected by cancer and drug treatment. The low trace elements level is a sign of leukemia patients, where cancer cells consume body nutrients and essential elements for growth. The Libyan patients were divided into four age groups and were either newly or old diagnosed with leukemia, including patients with acute leukocyte leukemia, acute myeloid leukemia, chronic myelogenous leukemia, and aplastic anemia. The samples were tested for direct aspiration onto inductively coupled plasma spectrometry at specific wave lengths. The findings showed the blood level of trace elements in leukemia patients is lower than in the healthy individuals. A negative correlation between copper and zinc levels in leukemia patients was found. The copper level increases in leukemia patients as they get older.

Education is power. It constitutes the foundation of all the multidimensional socio-economic development of a country. In the present context, we need manpower or human capital for generating the growth and development in a country. The Government of India has taken several many initiatives for promoting education at all the stages i.e. Primary, Secondary and Higher. But still, we find such issues as a high dropout rate at all the stages of education, rural-urban disparity, gender disparity, interstate variations pose as some of the problems that impedes the development of human resources in our country. Even the work participation rate in India indicates the necessity of proper planning of skill training and employment opportunity. Most interestingly, the existing general and conventional higher educational institutions have not effectively been able to cope with the contemporary challenges and changes with the result that the nature of curriculum which is by and large in place tends to create only degree inflation in our country. So, we need such institutes and institutional arrangement that can cater to the contemporary challenges so as to upgrade the quality of education as well as to provide need based educational programmes that can develop human power in the society. Effective or quality education especially at higher level can play a vital role in bringing around multifaceted human resource development, enabling the learner’s absorption in the job market and selfemployment. This paper will discuss how the accessibility of education can be promoted to all through a convenient mode of education system and how the disparities in education can be minimized, and also focus on the various strategies for strengthening higher education system in the country.
