The Impact of National Culture on Knowledge Sharing: The Moderate Role of Organizational Culture

Purpose: Examine the impact of national culture based on Hofstede’s concept of cultural dimensions on knowledge sharing and the moderate role of the organizational factors as success factors. Design\ methodology\ approach: The descriptive and inferential approach relying on a simple random sample among local and international employees working in Saudi Arabian Military Industries (SAMI) company. An electronic questionnaire distributed for this purpose. Findings: Collectivism, Femininity, LO, and SR are positively impact on KS, while PD, I, M, UA, SO, and ID are negatively impact the KS. Moreover, OC play a moderate role as success factor to maximize the advantage of PD, C, F, LO and SR and minimize the impact of I, M, UA, SO and ID on KS. In addition, the index of six national cultural dimensions of the sample understudy was compared to original Hofstede index and resulted on almost the same values. Originality / value: There are a few studies that examine the effect of the indulgence/self-restraint dimension. Moreover, most studies focus on single culture and there are a few studies that compare the national culture between two or more countries. Finally, there is no study has been conducted to examine the moderate role of organizational culture in this relationship. All of these aspects give uniqueness to this study and encourage to fill-up those gaps.
Seismic Interaction of Structures and Soils: Stochastic Approach

A study of soil-structure interaction for seismically excited simple structures is made considering both kinematic and inertial interaction effects. The information and concepts presented elucidate the nature and relative importance of the two effects and make it possible to assess readily the influences of the more important parameters. The response quantities examined are the ensemble means of the peak values of the lateral and torsional components of the foundation input motion and of the associated structural deformations. The results are evaluated over wide ranges of the parameters involved and are compared with those obtained for no soil-structure interaction and for kinematic interaction only. Simple, physically motivated interpretations are given for the observed differences. For the important special case of vertically incident incoherent waves, simple closed-form approximate expressions are presented for the transfer functions of circular massless foundations.
Learning to Bundle-adjust: A Graph Network Approach to Faster Optimization of Bundle Adjustment for Vehicular SLAM

Bundle adjustment (BA) occupies a large portion of the execution time of SfM and visual SLAM. Local BA over the latest several keyframes plays a crucial role in visual SLAM. Its execution time should be sufficiently short for robust tracking; this is especially critical for embedded systems with a limited computational resource. This study proposes a learning-based bundle adjuster using a graph network. It works faster and can be used instead of conventional optimization-based BA. The graph network operates on a graph consisting of the nodes of keyframes and landmarks and the edges representing the landmarks’ visibility. The graph network receives the parameters’ initial values as inputs and predicts their updates to the optimal values. It internally uses an intermediate representation of inputs which we design inspired by the normal equation of the Levenberg-Marquardt method. It is trained using the sum of reprojection errors as a loss function. The experiments show that the proposed method outputs parameter estimates with slightly inferior accuracy in 1/60–1/10 of time compared with the conventional BA.

Results: The analysis indicated that GHQ cut-off score did not differ significantly on any of the study variables; and the examined constructs (sexual abuse, physical abuse, parental loss with difficult in emotion regulation and neglect, physical abuse with alexithymia) were positively correlated with Difficulty as measured on Emotion Regulation Scale and Toronto Alexithymia Scale.
Shipboard Fire-Fighting Performance of Females and Males

A study of fire-fighting performance was conducted as part of an ongoing effort to identify potential gender-based human engineering problems resulting from the recent introduction of women to shipboard assignments in the Navy. Results of experimental simulations of fire fighting with a CO2 extinguisher and starting a P-250 pump were consistent with earlier questionnaire data, which indicated that females experienced difficulties with tasks requiring upper torso strength and grip strength. In the experiment, females registered significantly lower force values on the P-250 starter cord than did males, with lighter females exerting less force than heavier females. Females also exhibited a different pulling strategy than males did. Weight had no impact on the performance of males. The results revealed that 85% of the females and 5% of the males sampled would be incapable of starting the P-250 pump.
Covid-19 and Gastrointestinal Manifestations in Indian Patients: A Meta-Analysis.

Background India has the second highest number of confirmed Coronavirus cases in the world after the USA with 29.3 million cases reported so far. We aimed to perform a systematic review and meta-analysis of the clinical characteristics, comorbidities, and outcomes of SARS-CoV-2 positive patients with special emphasis on Gastrointestinal (GI) manifestations. Methods In this meta-analysis, we conducted a systematic review of high-quality articles on confirmed COVID-19 cases in India published in PubMed and Google Scholar between February 2020 and March 2021. Statistical descriptive analysis and correlation analyses of symptoms, comorbidities and outcomes were performed. Results The mean age of the patients was 46.16 years. Of these, 67.53% were males. Overall, 6.4% patients died. Cough (37.79%) was the most common presenting symptom followed by fever (35.5%), nasal congestion, and rhinorrhea (23.60%) but, these symptoms were unrelated to outcome. Patients with shortness of breath (r = 0.69, p = 0.03) and fatigue/weakness (r = 0.95, p = 0.04) had high mortality. Hypertension and Diabetes Mellitus were the most common comorbidities but were not associated with negative outcome. Preexisting chronic kidney disease (r = 0.80, p = 0.01), mechanical ventilation (r = 0.895, p = 0.003) and ICU admission (r = 0.845, p = 0.008) correlated with poor outcome. GI symptoms were reported in 12.05% of the patients. Nausea and vomiting were the most prevalent GI symptoms, but diarrhea (r = 0.95, p = 0.004) was associated with significant mortality. Conclusion Overall, COVID-19 patients in India present with cough, fever, shortness of breath and fatigue as the main symptoms. Among GI symptoms, diarrhea was associated with fatal outcomes. However, more high-quality studies are needed for better understanding of the GI manifestations and their outcomes in the Indian population.
Ge/sub x/Si/sub 1-x//silicon inversion-base transistors: theory of operation

A theoretical study of the device characteristics of the Ge/sub x/Si/sub 1-x//silicon inversion-base transistor (BICFET) is presented. This transistor uses the space charge of holes in a modulation-doped inversion channel to control vertical electron transport. This study is of interest not only because of the unique interaction of transport mechanisms in the BICFET but also because the BICFET is very well suited to the Ge/sub x/Si/sub 1-x//Si system, and offers substantial performance advantages over the BJT. The device characteristics presented are based on a numerical and analytical analysis using the drift-diffusion formalism. The effects that quantum confinement and non-semi-classical transport have on this structure are presented. The authors conclude with a comparison between the Ge/sub x/Si/sub 1-x//Si BICFET and Ge/sub x/Si/sub 1-x//Si HBT. >
Kuramoto-model-based data classification using the synchronization dynamics of uniform-mode spin Hall nano-oscillators

Oscillator-based data-classification schemes have been proposed recently using the Kuramoto model, which tries to capture the synchronization behavior of coupled oscillators without considering the underlying physics of the oscillation and the coupling. In this paper, we propose the hardware implementation of a Kuramoto-model-based data-classification scheme through an array of dipole-coupled uniform-mode spin Hall nano-oscillators (SHNOs). Using micromagnetic simulations, which capture the underlying physics of operation of the SHNOs, we first study the variation of synchronization range between two uniform-mode SHNOs as a function of the physical distance between them. Thus we correlate the coupling constant in the Kuramoto model with the dipole-coupling strength between two SHNOs, which our micromagnetic simulation takes into account. Next, we generate the synchronization map for the two-input–two-output dipole-coupled uniform-mode SHNO system through micromagnetics and show that it matches with the one predicted by the Kuramoto model. Thus, we demonstrate here that the synchronization behavior of SHNOs obtained from micromagnetics-based modeling is consistent with that obtained from the Kuramoto model, which ignores the underlying physics of the SHNOs. This suggests that the Kuramoto-model-based data classification scheme can indeed be implemented physically on an array of SHNOs. To verify our claim, we show, through micromagnetic simulation, binary classification of data from a popular machine-learning data set (Fisher’s Iris data set) using an array of uniform-mode SHNOs.
Bioaerosol Concentrations in the Quad Cities 1 Year after the 1993 Mississippi River Floods

Bioaerosol measurements were made in 45 Quad Cities, Illinois houses following the 1993 floods of the Mississip pi and Rock Rivers. Least squares log transformed means for fungal concentrations (in cfu m-3) were 1,449 in basements, 1,174 in living rooms, 1,234 in kitchens, 1,464 in first floor bedrooms, 1,197 in second floor bedrooms, and 2,590 outside. Mean least squares log transformed bacterial concentrations were 887 cfu m-3 in basements, 878 cfu m-3 in living rooms and 697 cfu m-3 outdoors. Levels of fungi and bacteria were not notably elevated in the basements or other rooms of the formerly flooded houses. Levels of fungi and bacteria indoors were significantly less in houses with dehumidifiers and in homes with natural gas odors. Air-conditioning during warm periods significantly reduced airborne concentra tions of fungi.
Effect The Addition Different Concentrations of Sodium Triphosphate and Sodium Lactate on The Microbial Count of Cold Ground Beef Meat

This study was conducted in the laboratories of Al-Musaib Technical College, Al-Furat Al-Awsat Technical University with the aim of studying the effect of adding sodium triphosphate salts at concentrations of 0, 0.5, 1, 1.5 and 2% and sodium lactate at concentrations of 0, 0.5, 1, 1.5 and 2% on the microbial count of ground beef and cooled for 24 hours at a temperature at 4 C. The results of the study indicated an increase in the rate of the total count of bacteria, psychrophilic bacteria, coliforms, yeasts and molds in all ground meat samples, not treated with salt, than the permissible limits. As samples of ground meat not treated with trisodium and sodium lactate salts recorded the highest rate in the total Count of bacteria after 24 hours of cold storage at 4 ° C, when they reached 6.544 CFU The Count of these bacteria decreased by increasing the concentration of salts, so the minimal count of bacteria was at a concentration of 2% when adding both salts of sodium triphosphate and sodium lactate together as 3.426 CFU. also found a clear reduction in the count of Psychrophilic bacteria at a concentration of 2% for both salts as recorded the last treatment rate 2.127 CFU It is the minimal count compared to the other treatments, while the control treatments recorded the highest count 6.400 CFU. Also, the addition of different concentrations of sodium triphosphate and sodium lactate led to a gradual decrease in the counts of coliform bacteria, with an increase in the salt concentration, as it reached 1.204 CFU At aconcentration of 2%, while the control treatment was recorded 6.431 CFU It is a the highest value. Also there is a significant difference was found (P <0.05). In the count of yeasts and molds, which were significantly decreased by increasing the concentration of both salts, as they were 1.079 CFU In the last treatment, while the highest count recorded since reached 4.361 CFU When salts are not added. This is a clear indication of the existence of a synergistic action of these salts to reduce the increasing counts of bacteria, yeasts and molds by inhibiting these microbial species with increased concentration.

It can be concluded that soaking maize seeds in humic acid improves yield and yield components.
Wind turbine blade vibration at standstill conditions — the effect of imposing lag on the aerodynamic response of an elastically mounted airfoil

The present study investigated physical phenomena related to stall-induced vibrations potentially existing on wind turbine blades at standstill conditions. The study considered two-dimensional airfoil sections while it omitted three-dimensional effects. In the study, a new engineering-type computational model for the aeroelastic response of an elastically mounted airfoil was used to investigate the influence of temporal lag in the aerodynamic response on the aeroelastic stability in deep stall. The study indicated that even a relatively low lag significantly increases the damping of the model. A comparison between the results from a model with lag imposed on all force components with the results from a model with lag imposed exclusively on the lift showed only marginal difference between the damping in the two cases. A parameter study involving positions of the elastic hinge point and the center of gravity indicated that the stability is relatively independent of these parameters. Another parameter study involving spring constants showed that the stability of each mode is dependent only on the spring constant acting in the direction of the leading motion of the mode. An investigation of the influence of the added mass terms showed that only the pitch-rate and flapwise-acceleration terms have any influence on the stability. An investigation of three different profiles showed that the stability is heavily dependent on the aerodynamic characteristics of the profiles—mainly on the lift. It was also shown that only the edgewise mode is unstable in deep stall. Moreover, independent of the amount of temporal lag in the aerodynamic response of the model, the inflow-angle region in the vicinity of 180° remains unstable in the edgewise mode. Therefore, this inflow-angle region may create stability problems in real life. The other type of vibrations potentially present at standstill conditions is vortex-induced, being outside the scope of the present study. Copyright © 2014 John Wiley & Sons, Ltd.
A survey of Nitrate and Nitrite Contents in Vegetables to Assess The Potential Health Risks in Kurdistan, Iraq

In this study, nitrate and nitrite contents were determined of a total (308) samples of 15 different types of vegetable such as leek, swiss chard, celery, spinach, garden cress, green onion, turnip, radish, aubergine, squash, tomato, pepper, cucumber, mint, and tarragon. They were taken from different fields located in Sulaymaniyah province: Sulaymaniyah city (Tanjarro and Kanaswra), Bazyan (Baynjan), Halabja (Said Sadiq), and Kalar (Grda Gozena). Using spectrophotometer measurements performed by UV/VIS double beam spectrophotometer at 538nm. The highest level of nitrate (529.55 mg/kg) for garden cress in Said Sadiq, (486.74 mg/kg) for Swiss chard in Kanaswra, and (477.65 mg/kg) for spinach in Bazyan. In addition, leek and celery contained high nitrate concentrations of about (416.65 and 447.60) mg/kg in Kanaswra and Bazyan, respectively. While the lowest nitrate concentration in fruiting vegetables like a tomato was 5.934 mg/kg in Bazyan, and aubergine in Grda Gozena was 5.617 mg/kg. Interestingly, the value of the Acceptable Daily Intake (ADI) and the Target Hazard Quotient (THQ) was lower than the standard limit, ADI for nitrate in this study was about (0.51, 2.18) mg/kg bw/day for adults and children, while the standard limit (3.70 mg/kg bw/day). Also, ADI for nitrite in this study was about (0.01, 0.05) mg/kg/bw for adults and children, while the standard limit was about 0 - 0.06 mg kg, as a result, the THQ ≤1. In summary, we can conclude that the amount of nitrates in raw vegetables was lower than the standard limit’s level and that this level does not cause health problems for consumers.
