Reliability Centred Maintenance Implementation For Overhead Transmission Lines In Al- Madinah Region

Use of overhead transmission lines in Al-Madinah region is something that has been used for several decades. However, their increased failure tends to present a critical effect on supply of electricity to the consumers in the region. In normal case, the fundamental motive for any power utility is to plan, operate, and maintain power infrastructure so that consumers can receive reliable electricity services at reduced expenses. This paper therefore aims at addressing the implementation of Reliability Centred Maintenance (RCM) in overhead transmission lines particularly in Al-Madinah region.
Child Skill Production: Accounting for Parental and Market-Based Time and Goods Investments

Les parents investissent du temps et de l’argent a la maison dans le developpement du capital humain de leurs enfants. Beaucoup investissent aussi de fortes sommes dans des services de garde lucratifs. De nombreuses politiques gouvernementales influencent ces decisions d’investissement. Leur incidence sur le bien-etre et le developpement des enfants depend de comment les familles reagissent en modifiant la repartition des investissements dans une periode donnee et au fil du temps. Dans la litterature, on estime habituellement les fonctions de production de capital humain chez les enfants de deux facons : soit on reduit les investissements pour chaque periode a un seul intrant composite, soit on fait des hypotheses sur la substituabilite entre les intrants. Dans cette etude, nous examinons une technologie qui definit les habitudes de substitution entre, d’une part, le temps et les biens et services achetes a la maison et, de l’autre, les services de garde achetes sur le marche. Nos estimations portent a croire a une complementarite entre le temps consacre par les parents et les biens et services a la maison, ainsi qu’entre ces intrants et les services de garde lucratifs. Il importe de tenir compte du degre de complementarite des intrants sous-entendu par nos estimations pour comprendre les tendances transversales des donnees ainsi que les reactions aux variations des prix sur les marches et aux changements de politiques.
Dynamics of charged particles in the field of an intense transverse electromagnetic wave

We give a rigorous solution that describes, in the laboratory reference frame, the dynamics of charged particles moving in the field of a fast or slow transverse electromagnetic wave with an arbitrary field strength. We determine the size of the interaction region where the particles effectively exchange energy with the field, and determine the dependence of the frequency of oscillations of passing and captured particles on the wave's field strength. We also formulate the conditions in which the particles are accelerated by the wave and the conditions in which the particles give up some of their energy to the wave. Finally, we show that even in a single interaction with the field, the transfer of energy from a flux of particles with a large energy spread to short-wave radiation can be highly efficient.

Distribution And Frequency Of Paraquat- Resistant Goosegrass (Eleusine Indica) Population On Cornfields In Simalungun Regency, Indonesia

Corn is one of the important cereal crops in Simalungun, which is the second-largest corn production area in North Sumatera, Indonesia. Reaching optimal corn production were inseparable from area weed management activities. Goosegrass (E. indica) was one of the most common weeds that often associate with corn cultivation. For weed control growers have been commonly using paraquat in Simalungun Regency. This study aimed to map the distribution and frequency of paraquat-resistant goosegrass on cornfields across the Simalungun Regency. Samples were collected from the 13 largest corn producer districts in Simalungun Regency. Sampling was carried out in areas that have been sprayed with paraquat for a minimum of 2 years. Samples were collected in March-July 2019 from 59 cornfields and one sample of paraquat-susceptible goosegrass which had never been applied with herbicide. The paraquat resistance test used the highest dose of 600 g b.a. ha. The results of the resistance test of 59 corn fields revealed 47 cornfields (80%) resistant to paraquat, 9 cornfields (15%) moderately resistant, and 3 cornfields (5%) susceptible. The level of paraquat resistance goosegrass was 20.83 100%.
Factors impacting postoperative haemorrhage after transnasal endoscopic surgery

Background: Transnasal endoscopic surgery (TES) is an established procedure for the treatment of chronic rhinosinusitis, septal deviation, and paranasal benign tumours. Postoperative haemorrhage (POH) is a common complication following TES. Various studies have addressed the risk factors for intraoperative bleeding and the methods to improve the operative field by reducing bleeding. However, the factors affecting POH following TES have not been fully elucidated. Therefore, we aimed investigate the risk factors for POH following TES. Methodology: We studied 807 patients who underwent TES. The variables between cases with and without POH were compared using univariate and multivariate models. We also examined the site and timing of bleeding. Results: POH was observed in 21 cases (2.6%). Seven cases required treatment in the operation room (0.9%). The most common sites of bleeding were around sphenopalatine foramen, and the median time to POH was the 7th day after surgery. Multivariate analysis showed that anti-thrombotic medication, low platelet count, and surgical indication for sinonasal tumour were independent risk factors for POH. Conclusions: POH after TES is a relatively common complication. Careful intraoperative haemostatic procedures may be required in these cases.

Reducing NOx emissions using 2-stage turbo charging

Miller T By cooling the combustion process using a Miller cycle, NOX emissions can be effi ciently reduced. This demands high boost pressures, which can be achieved with a 2-stage turbo charging (TC) system. Thus, these two technologies form an optimum combination. In order for the engine to cope with start-up problems caused by the cooler combustion chamber having earlier set inlet valve closure timings (IVC), a variable inlet valve closing (VIC) system will also be needed. Simulations made with a commercial 1D-simulation code have proven the potential that 2-stage turbo charging, together with extreme Miller timings, offers in respect of fuel consumption savings, as well as NOX emission reductions. As a result, a series of engine tests using a Wärtsilä 4-stroke medium-speed diesel engine was planned to verify the potential for this technology. The outcome of the tests, as well as the design changes needed to the engine, is reported in this article. The testing reported in this article has been performed with a prototype system. Several years of further development work needs to be invested, both on the engine as well as on the turbocharger side, in order to get 2-stage TC systems ready for production use.
University of Birmingham Designing ruthenium anticancer drugs

After nearly 20 years of research on the use of ruthenium in the fight against cancer, only two Ru(III) coordination complexes have advanced to clinical trials. During this time, the field has produced excellent candidate drugs with outstanding in vivo and in vitro activity; however, we have yet to find a ruthenium complex that would be a viable alternative to platinum drugs currently used in the clinic. We aimed to explore what we have learned from the most prominent complexes in the area, and to challenge new concepts in chemical design. Particularly relevant are studies involving NKP1339, NAMI-A, RM175, and RAPTA-C, which have paved the way for current research. We explored the development of the ruthenium anticancer field considering that the mechanism of action of complexes no longer focuses solely on DNA interactions, but explores a diverse range of cellular targets involving multiple chemical strategies.
Multinationals, Markets, and Markups∗

Over the last several decades there is increasing concern whether the concentration of economic activity in a small number of large firms has meant an increase in firm market power. While on the one hand technical and legal barriers to entry may have increased the ability of incumbent firms to raise mark-ups without fear of entry, on the other hand the growing concentration may have more benign causes such as technological change that favors greater scale of operations. This paper studies global market power by analyzing activities of U.S. multinational firms through the lens of a model in which firms tailor their mark-up to the local degree of competition. Employing data on virtually all US-owned firms operating across 50 countries for the years 1999 to 2014, we first show that the market power of manufacturing firms has risen substantially, and mostly due to higher mark-ups firm-by-firm: market share reallocation playing a minor role. Second, we confirm the model’s predictions that while high-productivity firms generally charge high mark-ups, they prefer to enter markets where a high degree of competition keeps mark-ups relatively low. Weaker firms, in contrast, tend to enter markets in which competition is low. This sorting implies that the average mark-up differences across locations taken at face value understate differences in the extent of competition across countries. Third, we show that the importance of firm sorting to countries has increased over time. The analysis highlights the importance of the firmmarket dimension when studying market power. ∗The statistical analysis of firm-level data on U.S. multinational corporations reported in this study was conducted at U.S. Bureau of Economic Analysis under arrangements that maintained legal confidentiality requirements.

Stellar Flares Detected By NGTS

Stellar flares are explosive events on the surface of stars, believed to be due to the release of magnetic energy in magnetic reconnection events [1]. These events are marked with a sudden increase of flux emission, followed by a gradual decay. This increase in flux takes place across a wide range of wavelengths, from radio to X-ray [2]. In particular there is a strong increase in UV emission. This UV emission can have damaging effects on nearby exoplanets, in particular on their atmospheres. Studies from [3] and [4] have shown the UV irradiation associated with a single large stellar flare from AD Leo, for an Earth-like planet, could deplete the ozone layer and irreversibly alter atmospheric chemical abundances. Further flares within a short timescale could then allow sudden UV irradiation to reach the planetary surface.
Femoral Bowing and Femoral Neck-Shaft Angle Evaluation Can Reduce Atypical Femoral Fractures in Osteoporotic Patients: A Scientific Report

Bisphosphonates (BPs) are the mainstay of osteoporosis treatment due to their safety and efficacy. There is evidence that BPs medication may be complicated by atypical femoral fractures (AFFs). Prolonged administration of BPs is even more strongly associated with AFFs. AFF is a relatively rare complication of BPs when taking into account the huge population worldwide that benefits from this pharmacotherapy. AFF is, however, a serious complication of BPs treatment, which includes prolonged healing time and high revision rate when operative treatment is required. Less frequently, AFFs occur even without BPs administration, while these fractures have all the characteristics of “stress” or “insufficiency” fractures. The critical point of view in AFFs pathogenesis seems to be not only the biology of cortical bone, but also the mechanical issue. It has been proven that BPs, glucocorticoids and proton pump inhibitors (PPIs) can cause bone turnover suppression and affect the biological parameter of AFFs pathogenesis. Specific mechanical femoral bone properties predispose to AFFs pathogenesis. Several studies have already reported that increased femoral bowing > 5.250 degrees or decreased femoral neck-shaft angle <125 degrees, are associated with increased risk for diaphyseal and subtrochanteric AFFs respectively, regardless of BPs uptake. If these two parameters are simultaneously present, the probability for AFFs occurrence increases dramatically. Our scientific report, which is based on the current evidence about AFFs, is that if both femoral bowing angle and femoral neck-shaft angle are evaluated before BPs administration, this intervention may reduce the incidence of AFFs. Thus, in cases with excessive lateral femoral shaft bowing or very small femoral neck-shaft angle, the prescription of another anti-osteoporotic treatment than BPs should be recommended. If, however, BPs can’t be avoided, clinicians should be aware of the fact that long-term administration may be implicated with AFFs occurrence. In these cases, short term BPs administration with timely drug holiday between three and five years may be reasonable. Finally, roentgenographic evaluation of both femurs every six months and medical reference in case of any emerging thigh pain are also logical interventions to prevent and reduce AFFs.
Radiomics: an overview in lung cancer management—a narrative review

Radiomics is a novel approach for optimizing the analysis massive data from medical images to provide auxiliary guidance in clinical issues. Quantitative feature extraction is one of the critical steps of radiomics. The association between radiomics features and the clinicopathological information of diseases can be identified by several statistics methods. For instance, although significant progress has been made in the field of lung cancer, too many questions remain, especially for the individualized decisions. Radiomics offers a new tool to encode the characteristics of lung cancer which is the leading cause of cancer-related deaths worldwide. Here, we reviewed the workflow and clinical utility of radiomics in lung cancer management, including pulmonary nodules detection, classification, histopathology and genetics evaluation, clinical staging, therapy response, and prognosis prediction. Most of these studies showed positive results, indicating the potential value of radiomics in clinical practice. The implementation of radiomics is both feasible and invaluable, and has aided clinicians in ascertaining the nature of a disease with greater precision. However, it should be noted that radiomics in its current state cannot completely replace the work of therapists or tissue examination. The potential future trends of this modality were also remarked. More efforts are needed to overcome the limitations identified above in order to facilitate the widespread application of radiomics in the reasonably near future.
UTILIZATION OF RHIZOSPHERE FUNGI TO CONTROL Fusarium oxysporum f.sp. capsici IN VITRO

Fusarium caused wilt disease in chilli pepper and destroyed some farmer crops. Results ofpreliminary research has been discovered that the disease caused by Fusarium oxysporum f.sp. capsici.The alternative environmental friendly method is to find antagonist microbes which is located in therhizosphere of healthy pepper plants. This study aims to find out potentially antagonistic fungi tocontrol Fusarium wilt disease on pepper plants. The fungi were isolated by soil dilution method orviable plate count method on Potato Dextrose Agar medium with antibiotic Livoplaxacin (25%, w/v). Rhizosphere fungi from healthy pepper plants had been identified. A total of 63 spesies belong to 4genera included Penicillium (45 species), Aspergillus (6 species), Trichoderma (9 species) andCandida (3 species). The highest percentage of distribution of rhizosphere fungi are P. digitatum(47.63%), P. expansum (19,05%), T. harzianum (9,53%), A. nidulans, A. niger, Penicillium sp. ,Candida albicans, and T. vitrens i.e 4,76% respectively. All of rhizosphere fungi colonies were foundto inhibit Fusarium oxysporum f.sp. capsici in vitro. The best inhibition was found in Aspergillusniger at 88.89 ± 2.2% followed by A. nidulans of 85,56 ± 1,6 %, T. harzianum at 84,45 ± 1,58% , andT. virens by 83,33 ± 1,2%, five days after inoculation. All of them have a very high inhibition criteria.
Experimental Characterization of a High-Damping Viscoelastic Material Enclosed in Carbon Fiber Reinforced Polymer Components

This work aims to identify the damping properties of a commercial viscoelastic material that can be embedded and cured between the layers of composite laminates. The material may be adopted for reducing the vibration response of composite panels, typically used in automotive and aerospace applications, e.g., as vehicle body shell components. In order to objectively estimate the actual potential to enhance the noise vibration and harshness aspects, the effects of the viscoelastic material on the modal parameters of carbon/epoxy thin panels are quantitatively assessed through experimental modal analysis. Two different experiments are conducted, namely impact hammer tests and shaker excitation measurements. Based on the results of the experimental campaign, the investigated material is confirmed as a promising solution for possibly reducing the severity of vibrations in composite panels, thanks to its high damping properties. Indeed, the presence of just one layer proves to triple the damping properties of a thin panel. An approximate damping model is derived from the measured data in order to effectively simulate the dynamic response of new design solutions, including thin composite panels featuring the viscoelastic material.
BIO-SAFETY OF MILK PRODUCTS AND Mycobacterium avium SUBSPECIES paratuberculosis AS MAJOR MICROBIAL CONTAMINANT USING MULTIPLE TESTS INCLUDING CULTURE AND SYBR GREEN REAL-TIME ASSAY

Twelve types of milk products belonging to 22 market brands were purchased from local shops in South Uttar Pradesh and were screened for the presence of Mycobacterium avium subspecies paratuberculosis (MAP) as major contaminant using six tests (microscopy, Indirect Fluorescent Antibody Test, IS 900 PCR, Indigenous Enzyme linked Immuno Sorbent Assay, dot_ELISA, and Latex agglutination Test). Sample positive in any one of the six tests was considered as positive. Of 276 milk products screened, the cumulative bio-presence of MAP was, 52.8% (146) and was highest in butter (75.0%), followed by curd (66.0%), buttermilk (52.9%), lassi (50.0%), cheese (40.0%) and ice-cream (28.5%). Bio-typing of MAP DNA from milk products using IS 1311 PCR_REA revealed presence of ‘Indian Bison Type’ as a major biotype. Kappa (0.700 – 0.815) and two-tailed p (<0.0001–1.0) values for six tests were significant for all six tests. This study for the first time revealed large scale contamination of ‘milk products’ marketed by leading commercial brands in India, with MAP bacilli and therefore not safe for human consumption. was highest and parallel. i_FAT was most sensitive followed by microscopy and d_ELISA. i_ELISA and LAT sensitivity in curd, buttermilk, ice-cream, and lassi. was superior for the screening of butter as compared to cheese, LAT was better. The study highlighted the selection of a test for screening milk products after considering the nature of milk products. Depending on resources, purpose, and sample we can choose the screening test(s). The use of RT_PCR and culture led to further confirmation of MAP in milk products.
