Review Design of Slot Antenna Based on Ansoft HFSS Software
Authors: Abdulhamid Mohanad , Ochieng Eugene 
Published: December 2019

Abstract
In this paper, a micro-strip fed slot antenna array for application in the 2.4GHz industrial, scientific and medical(ISM) band is implemented using the Ansoft HFSS software. Standard formulas are used to calculate different antenna parameters. The proposed antenna is designed to work at 2.4GHz frequency band. A half power beam width(HPBW) of 57°. A bandwidth of around 7.7% is attained. This may have been brought about by poor impedance matching and a high level of surface waves. A way of improving the bandwidth would have been to use proximity coupling feeding method which offers the highest bandwidth and is somewhat easy to model and has low spurious radiation. However, its fabrication would have been more difficult. A directivity of 2.01 dB is achieved. This is a fairly high though directivity increase could have been studied through use of different substrate material and thickness. Adjusting length and width of narrow slot loop antenna will influence on the resonance frequency and bandwidth. By using HFSS software, the characteristics of antenna are investigated and analyzed, including voltage standing wave ratio (VSWR), return loss and far field radiation patterns.

Abstract
Increased resistance to environmental stress at the cellular level is correlated with the longevity of long-lived mutants and wild-animal species. Moreover, in experimental organisms, screens for increased stress resistance have yielded mutants that are long-lived. To find entry points for small molecules that might extend healthy longevity in humans, we screened ∼100,000 small molecules in a human primary-fibroblast cell line and identified a set that increased oxidative-stress resistance. Some of the hits fell into structurally related chemical groups, suggesting that they may act on common targets. Two small molecules increased C. elegans’ stress resistance, and at least 9 extended their lifespan by ∼10–50%. We further evaluated a chalcone that produced relatively large effects on lifespan and were able to implicate the activity of two, stress-response regulators, NRF2/skn-1 and SESN/sesn-1, in its mechanism of action. Our findings suggest that screening for increased stress resistance in human cells can enrich for compounds with promising pro-longevity effects. Further characterization of these compounds may reveal new ways to extend healthy human lifespan.
Information Analytics in the Organizational Structure of Libraries of Top-Rated Universities in Ukraine
Authors: Kobelev O. M. 
Published: December 2019

Objective. To study of the organizational information and analytical structures of libraries of top-rated universities in Ukraine, in particular, of 4 domestic universities that entered the World University Rankings 2019. Methods. The methodological basis of the study is the basic provisions of the general theory of social communications. Comparative analysis, sociocommunicative, information, adaptive and other approaches are used. Results. The form of organization of information and analytical activities in the library depends on its place in the library system and the existing organizational structure therein. There are two options for its organization. The first option involves the distribution of tasks between the existing library departments. The second one is the creation of an independent analytical unit in the organizational structure of the library. In the libraries of the universities under study, information and analytical functions are performed by other departments, primarily by the information and reference (bibliographic) units, information service as well as scientific and methodological (research) departments. Conclusions. Thus, information and analytical activity, even for scientific libraries of leading Ukrainian universities, remains primarily a tool for improving internal library processes, and not a separate product (service) that is purposefully produced and offered to readers. Meanwhile, the intensification of the use of information and analytical technologies in libraries, the creation of specialized units therein is one of the effective tools for optimizing library work.

Background: Postoperative pulmonary complications (PPC) are one of the commonest complications following gastrointestinal surgery. They lead to increased mortality, increased length of intensive care unit (ICU) stay, and higher cost of treatment. Identifying the risk factors of PPC helps in predicting its occurrence and to develop preventive measures. The objectives of the present study were to study the clinical and demographic risk factors for PPC following gastrointestinal surgery.Methods: The study was designed as an observational descriptive analytic study. All the patients ≥18 years of age undergoing gastrointestinal surgery were included. The patients with preoperative lung pathology requiring ICU care or ventilatory support and patients with lung metastasis were excluded. The demographic and clinical parameters at admission were recorded. The details of pulmonary complications like the time of occurrence after surgery and the mode of treatment for pulmonary complications were noted. The risk association was assessed for statistical significance.Results: A total of 100 patients were underwent various gastrointestinal surgeries during the study period. The incidence of PPC was 34% in our study. Age, education status, smoking, and presence of comorbidities were found to be positively associated with an increased incidence of PPCs. The serum albumin of less than 3.5gm and the haemoglobin of less than 8 gm were also associated with an increased incidence of PPC. Pleural effusion was the commonest PPC seen in 15 (44.1%) patients followed by pneumonia in 9 (26.5%).Conclusions: Age, smoking, education status, serum albumin, haemoglobin, emergency surgery, elective postoperative ventilation, nasogastric intubation and blood loss in the intraoperative period were found to associated with increased risk of PPCs.

Background: Trauma represents a major challenge worldwide and is the leading cause of morbidity and mortality in young population. There is significant change in trauma related injuries due to urbanization, motorization, industrialization and the socioeconomic changes in India. Road traffic accidents (RTA) pose the largest threat to human lives and have become the number one public hazard all across the world causing morbidity and mortality. The aim of this study is to find out the demographics and to determine the injury pattern of surgical trauma cases presenting to this tertiary care zonal hospital.Methods: A prospective observational study was conducted in a tertiary care zonal hospital from June 2018 to December 2018. Data was collected for 105 patients presented with trauma in surgical emergency centre of this hospital were included in the study which excluded only orthopaedic trauma cases. The data collected was analysed.Results: Out of 105, 76 (72.38%) were male and 29 (27.61%) were female with 21 (20%) in the 31-40 age group. The average age of cases was 40.2 years. RTA was the major cause of trauma i.e. (77.14%) followed by accidental fall and slips (18.09%) and assaults (4.76%). Contusion was the common injury sustained (45.71%) followed by laceration (38.09%), abrasion (35.23%) and fracture (17.14%).Conclusions: There is a need for trauma registries which can help to formulate strategies towards decreasing the burden of trauma and improved outcomes at hospital as well as in public health.

Authors: R. Satishkumar , J. Anukethan 
Published: December 2019

Background: Gallstone disease is one of the most common problems affecting the digestive tract with a prevalence of 11% to 36% and is the most common cause of gall stone pancreatitis. The cholecystectomy is necessary to prevent recurrent pancreatitis in gallstone pancreatitis, but the ideal timing for cholecystectomy is controversial.Methods: This was a prospective randomized study with 59 patients conducted in the department of general surgery, KIMS, Bangalore from 2014 to 2019. All patient with mild gallstone pancreatitis, the following variables, duration and cost of hospital stay, readmission rates, intraoperative time, intra and postoperative complications and conversion to open cholecystectomy were studied.Results: A total of 59 patients in the age group of 21 to 71 years with mild gallstone pancreatitis were included in the study. Mean age of presentation was 57years. Out of 59 patients 28 underwent same admission cholecystectomy and 31 underwent interval cholecystectomy. There was a significant difference noted in terms of mean duration of hospital stay (9.28 versus 17.20 days), mean cost of hospital stay (19340 versus 28240rs) and readmission rate (0% versus 19.35%), but in terms of mean intraoperative time (85 min versus 92 min) and conversion rate (0% versus 6.4%) there was no statistically significant difference between two group.Conclusions: Same admission cholecystectomy for mild gallstone pancreatitis can significantly reduce cost and duration of hospital stay and readmission rates. With regard to intraoperative time, conversion to open, intraoperative and postoperative complication there is no statistically significant difference seen. Hence same admission cholecystectomy is safe, feasible and recommended.
The Analytical Thomist and the Paradoxical Aquinas: Some Reflections on Kerr’s Aquinas’s Way to God
Authors: Knasas John F.X. 
Published: December 2019

My article critically evaluates five key claims in Kerr’s interpretation of Aquinas’s De Ente et Essentia, ch. 4, proof for God. The claims are: (1) the absolutely considered essence is a second intention, or cognitional being; (2) à la John Wippel, the real distinction between essence and existence is known before the proof; (3) contra David Twetten, Aristotelian form is not self-actuating and so requires actus essendi; (4) the De Ente proof for God uses the Principle of Sufficient Reason; (5) an infinite regress must be eliminated before concluding to God. This author wonders if these questionable claims are traceable to the mindset of analytic philosophy which values precision and discreteness and so can fail to appreciate crucial paradoxes in Aquinas’s metaphysics.
Existence and God: On Aquinas–Kerr’s Metaphysical Argument
Authors: Wojtysiak Jacek 
Published: December 2019

In this paper, I discuss, as carried out by Gaven Kerr, a reconstruction of Aquinas’s argument for the existence of God from his work De Ente et Essentia. My analysis leads to complementing Kerr’s proposal with the following elements: (i) a summarization of the presented argument in a more formal manner; (ii) a specification of the main presuppositions of the Thomistic conception of existence; (iii) a drawing of attention to the fact that the essence–esse composition is a borderline case of the array of potency–act compositions; (iv) a distinguishing of the empirical (connected with the problem of the regress) and speculative (deprived of such a problem) interpretations or versions of Aquinas’s argument; (v) a clarification of what is the Divine exception from the essence–esse composition; (vi) a distinguishing of the three models of participation and a defence of the moderate model. I regard the following two issues to be of key importance for the argument under discussion: the relation between the Aristotelian compositional model and the Platonic model of participation as well as the defence of the Thomistic conception of the essence–esse composition.

Abstract
Background : In plants, the key roles played by RopGEF-mediated ROP signaling in diverse processes, including polar tip growth, have been identified. Despite their important roles in reproduction, a comprehensive analysis of RopGEF members has not yet been performed in rice ( Oryza sativa ). To determine whether RopGEF regulators are involved in rice pollen tube growth, we performed genome-wide analysis of this family in rice. Results : Phylogenomic and meta-expression analysis of eleven RopGEFs in rice showed that four genes were preferentially expressed in mature pollen. These four genes contain the plant-specific Rop nucleotide exchanger (PRONE) domain and possible phosphorylated residues, suggesting a conserved role in polar tip growth with Arabidopsis thaliana . In subcellular localization analysis of the four RopGEFs through tobacco ( Nicotiana benthamiana ) infiltration, four proteins were predominantly identified in plasma membrane. Moreover, double mutants of RopGEF2/8 exhibited reduced pollen germination, causing partial male sterility. These genes possess unique cis-acting elements in their promoters compared with the other RopGEF genes. Conclusions : In this study, four RopGEF genes were identified as pollen-specific gene in eleven members of rice, and the expression pattern, promoter analysis, and evolutionary relationship of the RopGEF family were studied compared with Arabidopsis. Our study indicated that four RopGEF genes might function during pollen germination in distinct subcellular localization. Our study could provide valuable information on the functional study of RopGEF in rice.
Implementation of the FilmArray ME panel in laboratory routine using a simple sample selection strategy for diagnosis of meningitis and encephalitis

Published: December 2019

Abstract
Background: Infectious meningitis is a serious disease and patient outcome relies on fast and reliable diagnostics. A syndromic panel testing approach like the FilmArray ME can accelerate diagnosis and therefore decrease the time to pathogen specific therapy. Yet, its clinical utility is controversial, mainly because of a remaining uncertainty in correct interpretation of results, limited data on its performance on clinical specimens and its relatively high costs. The aim of this study was to analyze clinical performance of the assay in a real life setting at a tertiary university hospital using a pragmatic and simple sample selection strategy to reduce the overall cost burden. Methods: Over a period of 18 months we received 4,623 CSF samples (2,338 hospitalizations, 1,601 individuals). FilmArray ME analysis was restricted to CSF-samples with a high pretest probability of infectious meningitis, e.g. conspicuous positive Gram-stain, samples in which leukocytes and/or bacteria were evident or urgent suspicion of infection was communicated by clinicians. N=171 samples matched to our risk criteria and were subjected to FilmArray ME analysis. Those samples were also analyzed by reference methods: culture only (n=45), PCR only (n=20) or both methods (n=106). Results: 56/171 (32.75 %) were FilmArray ME positive. Bacterial pathogens were detected in 30/56 (53.57 %), viral pathogens were detected in 27/56 (48.21 %) and yeast DNA was detected in 1/56 (1.79 %) of positive samples. Double detection occurred in 2/56 samples. In 52/56 (92.86 %) FilmArray ME positive samples, results could be confirmed by the reference assays (sensitivity=96.30%, specificity =96.58%).
Conclusion: The FilmArray ME assay is a fast and reliable diagnostic tool for the management of infectious meningitis and can easily be implemented in routine diagnostic workflows. However, correlation of test results and underlying clinical symptoms requires experienced users and the awareness of potentially false negative or false positive results. Moreover, considering the need for antimicrobial susceptibility testing, the use of molecular tests as a stand-alone diagnostic cannot be recommended.
