«The electronic magazine with rating system of an estimation of individual and collective work of students» (EM) is developed in document Microsoft Excel with use of macros. EM allows to automate all the calculated operations connected with estimation of amount scored by students in each form of the current control. EM provides automatic calculation of rating of the student with reflection of a maximum quantity of the points received in given educational group. The rating equal to “1” is assigned to the student who has got a maximum quantity of points for the certain date. For the other students the share of their points in this maximum size is indicated. The choice of an estimation is made in an alphabetic format according to requirements of the European translation system of test units for the international recognition of results of educational outcomes (ECTS - European Credit Transfer System), by use of a corresponding scale of an estimation. The list of students is placed on the first page of magazine and automatically displayed on all subsequent pages. For each page of magazine the optimal size of document printing is set with automatic enter of current date and time. Owing to accounting rate of complexity of task EM is the universal technical tool which can be used for any subject matter.

We introduce and study an inductively defined analogue [Formula: see text] of any increasing graph invariant [Formula: see text]. An invariant [Formula: see text] is increasing if [Formula: see text] whenever [Formula: see text] is an induced subgraph of [Formula: see text]. This inductive analogue simultaneously generalizes and unifies known notions like degeneracy, inductive independence number, etc., into a single generic notion. For any given increasing [Formula: see text], this gets us several new invariants and many of which are also increasing. It is also shown that [Formula: see text] is the minimum (over all orderings) of a value associated with each ordering. We also explore the possibility of computing [Formula: see text] (and a corresponding optimal vertex ordering) and identify some pairs [Formula: see text] for which [Formula: see text] can be computed efficiently for members of [Formula: see text]. In particular, it includes graphs of bounded [Formula: see text] values. Some specific examples (like the class of chordal graphs) have already been studied extensively. We further extend this new notion by (i) allowing vertex weighted graphs, (ii) allowing [Formula: see text] to take values from a totally ordered universe with a minimum and (iii) allowing the consideration of [Formula: see text]-neighborhoods for arbitrary but fixed [Formula: see text]. Such a generalization is employed in designing efficient approximations of some graph optimization problems. Precisely, we obtain efficient algorithms (by generalizing the known algorithm of Ye and Borodin [Y. Ye and A. Borodin, Elimination graphs, ACM Trans. Algorithms 8(2) (2012) 1–23] for special cases) for approximating optimal weighted induced [Formula: see text]-subgraphs and optimal [Formula: see text]-colorings (for hereditary [Formula: see text]’s) within multiplicative factors of (essentially) [Formula: see text] and [Formula: see text] respectively, where [Formula: see text] denotes the inductive analogue (as defined in this work) of optimal size of an unweighted induced [Formula: see text]-subgraph of the input and [Formula: see text] is the minimum size of a forbidden induced subgraph of [Formula: see text]. Our results generalize the previous result on efficiently approximating maximum independent sets and minimum colorings on graphs of bounded inductive independence number to optimal [Formula: see text]-subgraphs and [Formula: see text]-colorings for arbitrary hereditary classes [Formula: see text]. As a corollary, it is also shown that any maximal [Formula: see text]-subgraph approximates an optimal solution within a factor of [Formula: see text] for unweighted graphs, where [Formula: see text] is maximum size of any induced [Formula: see text]-subgraph in any local neighborhood [Formula: see text].

Purpose This study aims to empirically examine whether there is any optimal Shari’ah supervisory board’s (SSB) size that maximizes performance of Islamic banks (IBs). Apparently, IBs adopt different SSB size based on their different regulations across jurisdictions, and then it is still questionable whether there is any optimal SSB size that can fit all and be recommended to IBs. Design/methodology/approach The paper investigates the impact of different SSB size on IBs performance using a sample of 113 banks over 23 countries for the period 2007-2015 based on the generalized method of moments estimator. Findings The empirical evidence documented in this study strongly highlights the importance of small SSB size in enhancing the performance of IBs as compared to the large board size. The findings confirm that the SSB size of IBs should neither be lesser than three nor greater than six. More specifically, it is found that the optimal SSB size seems to be five. Research limitations/implications First, the study does not investigate whether the findings are constant during crisis and non-crisis periods. Second, the optimal SSB size in IBs should be confirmed from the risk-taking perspective besides performance. Practical implications For both the IBs and the regulators, they should give due importance to small SSB size as an important element for improving the IBs performance. It is strongly recommended for the IBs to have a SSB size between three and six, and five is the most recommended. The Accounting and Auditing Organization for Islamic Financial Institutions also should revise their existing standards that only suggest the minimum SSB size of three to include the maximum size of six and the optimal size of five. Originality/value Despite the SSB size plays an important role in affecting the performance of IBs, it seems there are no empirical studies attempting to address whether there is any optimal SSB size that can enhance the IBs performance so far.

AbstractIntroductionTimely diagnosis is essential for the containment of the disease and breaks in the chain of transmission of SARS-CoV-2. The present situation demands countries to scale up their testing and design innovative strategies to conserve diagnostic kits and reagents. The pooling of samples saves time, manpower, and most importantly diagnostic kits and reagents. In the present study, we tried to define the pool size that could be applied with acceptable confidence for testing.Material and methodsWe used repeatedly tested positive clinical sample elutes having different levels of SARS CoV 2 RNA and negative sample elutes to prepare seven series of 11 pools each, having pool sizes ranging from 2 to 48 samples to estimate the optimal pool size. Each pool had one positive sample elute in different compositions. All the pools were tested by SARS CoV 2 RT-qPCR.ResultsOut of the 77 pools, only 53 (68.8%) were found positive. The sensitivity of pools of 2 to 48 samples was decreased from 100% (95% CL; 98.4-100) to 41.41% (95% CL; 34.9-48.1). The maximum size of the pool with acceptable sensitivity (>95%) was found to be of 6 samples. For the pool size of 6 samples, the sensitivity was 97.8% and the efficiency of pooling was 0.38.ConclusionThe pooling of samples is a practical way for scaling up testing and ultimately containing the further spread of the COVID-19 pandemic.

Abstract The purpose of this article is to provide clinical supervisors with information pertaining to state-of-the-art clinic observation technology. We use a novel video-capture technology, the Landro Play Analyzer, to supervise clinical sessions as well as to train students to improve their clinical skills. We can observe four clinical sessions simultaneously from a central observation center. In addition, speech samples can be analyzed in real-time; saved on a CD, DVD, or flash/jump drive; viewed in slow motion; paused; and analyzed with Microsoft Excel. Procedures for applying the technology for clinical training and supervision will be discussed.

SummaryA new in vivo method to study the size and dynamics of a growing mural thrombus was set up in the rat femoral vein. The method uses a standardized crush injury to induce a thrombus, and a newly developed transilluminator combined with digital analysis of video recordings. Thrombi in this model formed rapidly, reaching a maximum size 391 ± 35 sec following injury, after which they degraded with a half-life of 197 ± 31 sec. Histological examination indicated that the thrombi consisted mainly of platelets. The quantitative nature of the transillumination technique was demonstrated by simultaneous measurement of the incorporation of 111In labeled platelets into the thrombus. Thrombus formation, studied at 30 min interval in both femoral veins, showed satisfactory reproducibility overall and within a given animalWith this method we were able to induce a thrombus using a clinically relevant injury and to monitor continuously and reproducibly the kinetics of thrombus formation in a vessel of clinically and surgically relevant size

Objective: The present epidemiological study was conducted with the objectives of providing an insight into the current use of antidiabetic medications to diabetics and hypertensive diabetics in urban areas and determining how the patient factors influence the prescribing of antidiabetic medications. Methodology: Data of patients of past two years were collected from Bangabandhu Sheikh Mujib Medical University (BSMMU) Hospital, Dhaka, Bangladesh. The details were entered in the structured patient profile form. Data were statistically analyzed using the Microsoft Excel 2007 software. Result: A total of 958 patient’s data were collected and analyzed of which 632 (65.97 %) were males and 326 (34.03 %) were females. These patients were further categorized based on their age. 330 patients (34.45 %) belonged to the age group 20 – 44 years, 504 (52.61 %) to the age group 45 – 65 years and 124 (12.94 %) to the age group 65 – 80 years. 684 (71.4%) patients out of the 958 patients studied were suffering from coexisting hypertension. Co-existing hypertension was found to be more prevalent in the age group 45 – 65 years (67.69%) and was found more in females (84.04%). Conclusion: Metformin was the oral hypoglycemic which was the highest prescribed. In hypertensive diabetics Metformin and Pioglitazone were most frequently prescribed drugs. Biguanides and Insulin were the most commonly prescribed antidiabetics. A combination of two or more drugs of different classes was prescribed to hypertensive diabetics. It is necessary to have an improved understanding of the etiology and pathophysiology of diabetes to focus on research efforts appropriately.
