EXPERIMENTAL DETERMINATION OF REAL AND IMAGINARY PARTS OF FOURIER-COEFFICIENTS OF POLARIZABILITY OF ADP AND KDP CRYSTALS BY DYNAMICAL DIFFRACTION OF X-RAY

Integrated intensity of diffracted of X-ray beams was registered from single crystal of ammonium dihydrogen phosphate (ADP) in the Laue geometry under influence from different temperature gradient and was observed a minimum in integrated intensity dependence on the temperature gradient. Formula for integral intensity of reflection in crystals with weak deformation has been applied to reflecting planes and extracted values of χih and χrh (the imaginary and real parts of coefficient of Fourier expansion of polarizability). Similarly, this method was used for KDP crystal and the results are compared with theoretical values.
Nutritional status of iodine in schoolchildren of Islamabad, Pakistan: a comparison with the WHO references

Background : The northern Himalayan section of Pakistan has a historical significance of iodine deficiency. The capital territory of Islamabad is in a plateau of these mountains which may be iodine deficient despite the rest of the country has improved to the optimal status of iodine in schoolchildren. We conducted this study to evaluate the iodine status in schoolchildren of Islamabad and adjacent areas by measuring urinary iodine concentrations (UIC) and thyroid volumes. Methods: Schoolchildren of the age group from 9 to 12 years ( n = 264) belonging to both the rural and urban areas of the region were included in this study. UIC was measured in urine samples by Sandell–Kolthoff kinetic method, and the thyroid volumes were determined by ultrasonography. A dietary history in iodine intake was recorded, and the samples of the household salt from 51 houses were also assessed for iodine content. Results: The median of UIC was below the standard values in both boys and girls. The 97th and 50th percentiles of thyroid volumes of our population at various points of age and body surface area were significantly higher than the reference values. Dietary intake of iodine-rich food was not sufficient, and the iodine content in table salt was lower than the required value. Conclusions: This study revealed that schoolchildren in the capital territory of Islamabad are iodine deficient. The iodine status in this region is consistent with other northern areas of Pakistan.
Sensorless Control of DFIG Wind Turbine Systems Based on SOGI and Rotor Position Correction

In this article, a novel sensorless control scheme for doubly fed induction generator (DFIG) wind turbine systems based on the second-order generalized integrator (SOGI) and rotor position correction (RPC) is proposed. The rotor speed can be estimated from the SOGI structure with the inputs of the measured rotor currents and the grid frequency. Since the SOGI has the characteristic of the adaptive filter, the accurate estimation of rotor speed can be achieved despite the harmonics in the measured quantities. The RPC uses the SOGI outputs and the rotor currents, which are found based on the measured stator currents and voltages, to eliminate the estimated rotor position error. The effects of parameter variation on the estimation are investigated as well. The simulation and experimental results have verified the validity of the proposed method under the wind speed fluctuations and adverse grid conditions.
Human-Centered Design as a Frame for Transition to Remote Teaching during the COVID-19 Pandemic

Teacher education programs all around the world are challenged with the emergency transition to remote teaching due to the COVID-19 pandemic. Human-centered design can help generate creative solutions to the pedagogical problems that teacher educators face during this transition. In this paper, we present a case of the Principles and Practices of Digital Learning course offered to preservice teachers in the Learning Technologies minor program at a Midwestern university. Our human-centered design approach followed three premises: (a) Building empathy, (b) engaging in pedagogical problem solving and (c) establishing an online community of inquiry. We present our process and the results with a design frame that can be used in other teacher education contexts.
Dividend payment policy across food industry companies – the case of European economies

The purpose of the paper is to examine the factors influencing the dividend payout policy. Our analysis is based on unbalanced panel data with 4 582 observations of companies from 35 countries over 20 years, 1999-2018. The study covers the companies that are listed on European stock exchange and also includes countries that are not in the EU. The factors that influence the dividend payment decision were identified. The advantage of a positive relationship between dividend payout is based mostly on the previous dividend payout decision. This shows the need to continue the undertaken dividend policy which reflects investors’ expectations in this sector. Overall, the evidence supports that the productivity of a food sector companies’ impact on the decision of dividend payment is even stronger that the level of profitability and size of a company. The debt level has a negative relationship with the dividend payout ratio. However, its impact was weak, mostly because of the low debt level in the case of food sector companies. Our evidence supports the agency and information asymmetry theory and contributes to international business research across intra-industry dividend policy characteristics.

The prevalence of various eyelid skin lesions in a single-centre observation study

Introduction The role of the eyelids is to protect and moisturise the eye. Despite its small relative surface area, 5–10% of skin cancers originate in the eyelids. Aim To assess the prevalence of different types of skin lesions in the area of eyelids based on retrospective histopathology data from a tertiary centre. Material and methods Among 544 included eyelid lesions, 429 (79%) were benign and 115 (21%) were malignant. In the benign group, the most common finding was a chalazion (49.2%) followed by squamous papilloma (22.8%), seborrheic keratitis (10%), epidermal cyst (8.2%), and intradermal nevus (5.1%). Out of all malignant lesions, the most common diagnosis was basal cell carcinoma (BCC) in 110 (95.7%) patients. Results Squamous cell carcinoma (SCC) was diagnosed in 3 (2.6%) patients and sebaceous gland carcinoma (SGC) in 2 (1.7%). No malignant melanoma was identified in the studied group. Conclusions Although benign lesions are the most common eyelid tumours, it is essential to differentiate between benign and malignant eyelid tumours because early detection and appropriate treatment may improve the cosmetic effect and reduce recurrences.
Review on effective role of UAV in precision farming

Recently, unmanned aerial vehicles (UAVs) have rapidly emerged as a new technology in the fields of agriculture. Small, unmanned aircraft systems (UAS) provide an opportunity for multiple uses in agriculture sectors viz land mapping, soil testing, pesticide spray application, weed management etc. in which the applicator can be displaced from close proximity for its effective application. As the world population will exceed, to feed them, the agricultural sector must increase production by 70%. The number of resources suitable for use in agriculture - land, water, energy - will decline. Here the farmers have to rely primarily on support of new technologies that not only increase production with limited resources, but also improve its effectiveness. The object of the review paper is the analysis of the latest technology available in the market and its effective use in Agricultural field. As well as advanced direction of crop capacity increasing in agriculture with help of Unmanned Aviation System. The use of modern unmanned aerial vehicles will extend the benefits of small aircraft. This paper also presents an embedded hardware/software architecture specially designed to be applied on mini/micro Unmanned Aerial Vehicles (UAV).

Substitution Effect of Maize (Zea Mays) with Grain Milling By-Products on Egg Production and Hatchability of Eggs in White Leghorn Layer Hens

The substitution effect of maize grain with grain milling by-products (GMP) was investigated on egg production and fertility parameters in White Leghorn layer hens. To this effect, four treatment (T) diets were formulated to contain GMP (g/kg) at zero (T1), 100 (T2), 150 (T3) and 200 (T4) by partially replacing the maize grain. One-hundred forty four White Leghorn layer hens were allocated randomly to the treatment diets, replicated thrice consisting of 12 hens each. The experiment was conducted for 20 weeks. The results indicated that the hen-housed egg production and daily egg mass output was higher (p<0.001) in hens fed with T1 and T2 diets than those of T3 and T4. Birds fed with T1 diet produced heavier (p<0.001) eggs than those reared in T2, T3 and T4 diets, the former being significantly different with the latter two. The daily feed intake differed significantly among treatment diets being higher (p<0.001) in birds fed with T1 and T2 than that of T3 and T4 diets, which had similar values. No significant difference was observed in hen-housed egg production, daily egg mass output, and daily feed intake among hens fed with T1 and T2 diets. Similarly, no significance difference was observed in egg weight, total and daily feed intake between hens fed with T3 and T4 diets. The feed conversion ratio (FCR, kg feed/kg egg mass) were different among treatment diets in which the lowest value being observed in those chickens reared in T1 followed by T2 diets. Birds fed with T4 diet had the highest FCR as compared with the rest of the treatment groups. Fertility and hatchability of eggs set were similar among chickens reared in T1 and T2 diets; but were higher (p<0.05) than those of T3 and T4 which had similar values. However, hens fed with T4 diet had lower (p<0.05) value in hatchability of fertile eggs than the rest of other treatments. In conclusion, the substitution of maize grain with 10% GMP showed similar effect with that of the control group in all studied performance parameters. Thus, GMP could be safely incorporated in replacement of maize for layer hen diets up to 10%.

Genetic variability, heritability and genetic advance in durum wheat (Triticum durum L.)

An experiment was carried out to assess genetic variability with respect to grain yield and its attributes with a set of 40 genotypes of durum wheat (Triticum durum L.). The analysis of variance revealed highly significant differences among the mean square due to genotypes for all the characters studied. The values of phenotypic coefficient of variation were slightly higher than that of genotypic coefficient of variation for all the traits studied, indicating less effect of environment on the expression of characters studied. High genotypic and phenotypic coefficient of variation were observed for grain yield per plant followed by grain weight per main spike, number of grains per main spike, 100-grain weight, number of productive tillers per plant and biological yield per plant. High heritability coupled with high to moderate genetic advance expressed as per cent of mean were observed for days to 50% flowering, number of productive tillers per plant, plant height, ear length, grain yield per plant, biological yield per plant and 100-grain weight, which may be attributed to the preponderance of additive gene action and possessed high selective value and thus, more emphasis should be given to these characters for genetic improvement of grain yield.
Morning resolutions, evening disillusions: Theories of willpower affect how health behaviours change across the day

People may be more or less vulnerable to changes in self-control across the day, depending on whether they believe willpower is more or less limited. Limited willpower beliefs might be associated with steeper decreases in self-control across the day, which may result in less goal-consistent behaviour by the evening. Community members with health goals (Sample 1; N = 160; 1814 observations) and students (Sample 2; N = 162; 10,581 observations) completed five surveys per day for one to three weeks, reporting on their recent physical activity, snacking, subjective state, and health intentions. In both samples, more limited willpower beliefs were associated with less low- and moderate-intensity physical activity, particularly later in the day. Limited willpower beliefs were also associated with more snacking in the evenings (Sample 1) or overall (Sample 2). These behavioural patterns were mediated by differential changes in self-efficacy and intentions across the course of the day (in Sample 1), and the above patterns of low- and moderate-physical intensity held after controlling for related individual differences, including trait self-control and chronotype (in Sample 2). Overall, more limited willpower theories were associated with decreasing goal-consistent behaviour as the day progressed, alongside decreasing self-efficacy and weakening health-goal intentions.
Board/Executive Gender Diversity and Firm Financial Performance in Canada: The Mediating Role of Environmental, Social, and Governance (ESG) Orientation

The objective of this study is to verify the effect of gender diversity on the board of directors (BD) and the executive committee (EC) of participating Canadian firms with regard to the financial performance and the mediating role of environmental, social, and governance (ESG) orientation in this relationship. The study sample was composed of 133 Canadian firms, and the data cover an 18 year timeline (2002–2019), with 925 observations. This paper provides empirical support for the effect that gender diversity in turnover has on the financial performance of firms and explains 53% of its variance. In addition to supporting the beneficial effect of gender diversity on performance, the study reveals the mediating mechanism through the ESG orientation of companies explaining almost 4% of the total effect of gender diversity on performance. By analyzing two levels of diversity, the study revealed the superiority of the effect of gender diversity in BDs as compared to ECs. We discuss the theoretical and empirical implications of the results found, as well as the limitations and future prospects of research on the subject.
Vehicular Localization Based on CSI-Fingerprint and Vector Match

In order to design a fast and accurate short-distance localization system to supplement the gap of Global Position System (GPS) in a toll station, in this paper, an IEEE 802.11p module driver is modified to provide channel state information (CSI), and the signal processing techniques are leveraged in both time-domain and frequency-domain to mitigate multi-path effect. An effective CSI vector provided by a roadside unit (RSU) transceiver (RX) array is treated as the fingerprint of a transmitting spot, the spatial diversities of the multiple antennas are leveraged to highlight its position feature. The position similarity degree of a reference point with regard to the measured vehicle position is proposed and treated as weight to calculate vehicle coordinate, the low variability of CSI-fingerprint is alleviated. A filter is designed to cut off the dataset of remote reference points in localization algorithm, traffic noises are reduced. Finally, the accuracy and performance are verified in enforcement, autopilot and navigation applications. The effects of grid size, speed, traffic and weather are evaluated.
High-Throughput Sequencing Based Methods of RNA Structure Investigation

Detection of reverse transcriptase termination sites is important in many different applications, such as structural probing of RNAs, rapid amplification of cDNA 50 ends (50 RACE), cap analysis of gene expression, and detection of RNA modifications and protein–RNA cross-links. The throughput of these methods can be increased by applying massive parallel sequencing technologies. Here, we describe a versatile method for detection of reverse transcriptase termination sites based on ligation of an adapter to the 30 end of cDNA with bacteriophage TS2126 RNA ligase (CircLigaseTM). In the following PCR amplification, Illumina adapters and index sequences are introduced, thereby allowing amplicons to be pooled and sequenced on the standard Illumina platform for genomic DNA sequencing. Moreover, we demonstrate how to map sequencing reads and perform analysis of the sequencing data with freely available tools that do not require formal bioinformatics training. As an example, we apply the method to detection of transcription start sites in mouse liver cells.
Analgesic Safety of Periodic Intravenous Infusion of Acetaminophen After Hepatectomy: A Propensity Score Matching Analysis

Background and Aim: Acetaminophen is an often-used analgesic for management of postoperative pain; it is not associated with hypomotility of the gastrointestinal tract or postoperative nausea and vomiting. It may, however, negatively affect liver function. Thus, acetaminophen is rarely used after hepatectomy and there are few studies pertaining to the analgesic safety of such use. We investigated the analgesic safety of periodic intravenous infusion of acetaminophen following hepatectomy. Patients and Methods: The study included 92 patients who had undergone hepatectomy without biliary reconstruction at St. Marianna University Hospital between January 2014 and November 2018. These patients were identified from among a larger group of patients, and propensity score matching allowed for the creation of two study groups: 46 patients who had undergone periodic intravenous infusion of acetaminophen for postoperative pain management (Group A), and 46 control patients who had undergone bolus injections of the non-steroidal antiinflammatory drug upon request (Group C). The two groups were then compared retrospectively in terms of clinical characteristics; operative variables; details regarding postoperative analgesia; concentrations of serum liver enzymes (total bilirubin [TBL], aminotransaminases aspartate aminotransferase [AST], alanine aminotransferase [ALT], alkaline phosphatase [ALP] and gamma-glutamyl transpeptidase [γGTP]) determined preoperatively, on postoperative days (PODs) 1, 3 and 7, and between PODs 14 and 28; and in-hospital outcomes and complications. Results: Patients’ clinical characteristics and operative variables did not differ between the two groups. Of the liver enzymes, only the serum γGTP concentrations observed on POD 7 and POD 14 differed significantly (p=0.003 and p=0.017, respectively). No patient suffered CTCAE Grade ≥ 3 hepatic failure, and there was no mortality. Conclusion: Results of our study indicate that periodic intravenous infusion of acetaminophen after hepatectomy is a safe means of managing patients’ postoperative pain.
Etude des propriétés mécaniques et tribologiques de couches minces nanostructurées : cas du carbure de chrome

A l’echelle nanometrique, la determination des proprietes mecaniques et tribologiques des revetements est un sujet de recherche d’actualite. Dans ce cadre, le travail presente a pour but d’etudier les proprietes mecaniques des couches minces nanostructurees. Dans un premier temps, nous avons mis en evidence une methode experimentale permettant la determination des proprietes tribologiques de couches minces. Cette etude a porte sur les couches minces de titane et de nitrure de titane deposes par pulverisation cathodique RF sur des substrats monocristallins de Si (100). Nous montrons l’importance du taux de chargement normal sur la determination du deplacement normal de l’indenteur et de la force tangentielle dans le cas de la rayure a force normale croissante. Nous avons egalement montre que la mesure de la force tangentielle est fortement dependante de l’orientation de l’indenteur de type Berkovich lors de l’essai de rayure. L’effet de l’orientation de la pointe Berkovich a ete egalement etudie dans le cas des essais d’usure. Dans un deuxieme temps, nous avons elabores des films minces de carbure de chrome sur des substrats monocristallins de Si (100) et MgO (100). Les echantillons ont ete caracterises par reflectometrie et diffraction des rayons X. La composition des films a ete determinee par la technique WDS. Les proprietes microstructurales, structurales et mecaniques ont ete etudiees en fonction de la temperature du substrat et de la teneur des films en carbone. Un renforcement des proprietes mecaniques et de la resistance a l’usure a ete observe avec l’augmentation de la temperature de depot. L’effet de la taille des grains et de l’etat de cristallisation des films sur la durete et la resistance a l’usure des films est discute
