The purpose of this study is to examine the relationship between POS, JR, and Innovation, and to explore the role of job psychological empowerment as a mediator in this relationship. A structured questionnaire was distributed to 25 companies in the petrochemical industry. PLS-SEM 4 was used to analyze the data of 100 valid responses. These findings suggest that employee empowerment (EMPOW) fully mediates the relationship between job resourcefulness (JR) and Innovation (INNOV). The total effect of JR on INNOV is also significant, with a beta coefficient of 0.234 and a t-value of 3.375. However, when the mediating influence of EMPOW is taken into account, the effect of JR on INNOV is no longer significant, with a beta coefficient of 0.100 and a t-value of 1.610. This suggests that EMPOW plays a key role in the relationship between JR and INNOV and that JR may not have a direct impact on Innovation. The study informs the development of interventions or strategies for promoting Innovation in organizations by identifying key factors that facilitate or inhibit the innovation process. The study further contributes to the development of new theories or models on the relationship between perceived organizational support, job resourcefulness, psychological empowerment, and Innovation.

The current study examines the nexus between the capital structure (debt-equity) and firm value (Tobin’s Q) by including profitability (alternatively Return on Assets (ROA) and Return on Equity (ROE)) as a moderator in the companies of Saudi Arabia. The study sample consists of 102 companies listed on Tadawul (the Saudi Arabian stock exchange) from different sectors of Saudi Arabia during the period 2013 to 2020. The study estimates pooled regression, panel regression with fixed and random effects, and dynamic panel regression models to report the results. The study results report that there is a negative and significant association between capital structure and firm value in model 1, while in models 2 and 3 there is a more negative and significant impact between the two study variables compared to model 1 after the inclusion of interaction variable, i.e. profitability in terms of ROA and ROE. The comparative result shows that the companies of Saudi Arabia hold more debt in their capital structure mix, hence evidencing a decrease in the firm value. The reported results also show that models 2 and 3 are better in explaining the impact of capital structure on firm value due to the interaction of profitability compared to model 1.

Watermelon (Citrullus lanatus) is commonly consumed by humans and widely available around the world. It has impressive nutritional properties, a rich phytochemical profile, and various claimed medicinal and health benefits. The major carotenoids in watermelon include lycopene, β-carotene, phytofluene, phytoene, lutein, and neurosporene. Lycopene (approximately 6,888 μg/152 g) is the major bioactive component in the fruit and it reportedly promotes several therapeutic effects, such as anti-cancer and anti-inflammatory activities etc. in humans and animals. Watermelon is also a good source of the amino acid citrulline, which is involved in production of arginine. Pre- and postharvest factors, including fruit sampling area, application of fertilizer, climatic factors, and genetic variability, are known to affect its bioactive compounds and nutrient concentrations. This review summarizes our current understanding of the watermelon phytochemical profile and the factors affecting its bioactivities and therapeutic effects.

With ever-advancing computer technology, the Monte Carlo (MC) neutron transport calculation isexpanding its application area to nuclear reactor transient analysis. Dynamic MC (DMC) neutron trackingfor transient analysis requires efficient algorithms for delayed neutron generation, neutron populationcontrol, and initial condition modeling. In this paper, a new MC steady-state simulation method based ontime-dependent MC neutron tracking is proposed for steady-state initial condition modeling; during thisprocess, prompt neutron sources and delayed neutron precursors for the DMC transient simulation caneasily be sampled. The DMC method, including the proposed time-dependent DMC steady-state simulationmethod, has been implemented in McCARD and applied for two-dimensional core kineticsproblems in the time-dependent neutron transport benchmark C5G7-TD. The McCARD DMC calculationresults show good agreement with results of a deterministic transport analysis code, nTRACER.

Nadeem, Sohail,Lee, Changhoon Springer 2012 NANOSCALE RESEARCH LETTERS Vol.7 No.1
<P>The steady boundary layer flow of nanofluid over an exponential stretching surface is investigated analytically. The transport equations include the effects of Brownian motion parameter and thermophoresis parameter. The highly nonlinear coupled partial differential equations are simplified with the help of suitable similarity transformations. The reduced equations are then solved analytically with the help of homotopy analysis method (HAM). The convergence of HAM solutions are obtained by plotting <I>h</I>-curve. The expressions for velocity, temperature and nanoparticle volume fraction are computed for some values of the parameters namely, suction injection parameter <I>α</I>, Lewis number <I>Le</I>, the Brownian motion parameter <I>Nb </I>and thermophoresis parameter <I>Nt</I>.</P>
Integration of context awareness in Internet of Agricultural Things
Nadeem Javaid 한국통신학회 2023 ICT Express Vol.9 No.2
This work explores an efficient integration of IoT devices based on context awareness in the agricultural sector. A four-layered framework is proposed in which automation techniques are embedded to get real-time context aware insights from the ecosystem of IoT. The framework is evaluated using a strategic tool called threats, opportunities, weaknesses and strengths (TOWS) matrix to measure the performance of automation techniques. This analysis points out various opportunities to innovate the livelihood of agrarian society around the globe.
A modified non-linear model for high mass ratio square cylinder
Nadeem A. Sheikh,S. Manzoor,S. Khushnood 대한기계학회 2014 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.28 No.12
An improved analytical method for the modelling of vortex induced vibrations (VIV) of a square section cylinder is reported. Themethod is based on a typical structural oscillator coupled to a non-linear wake (Van der Pol) oscillator. Improvements are introduced tothe pre-existing analytical methods sorted out from the literature. Dissipation term in the structural oscillator model is modified by theaddition of a non-linear damping term. Definition of the wake oscillator is updated simultaneously to include stream-wise force componentexerted on the structure. Results show that our modified analytical method correctly predicts the location of peak lock-in amplitudeon the amplitude vs reduced-velocity map as observed in recent experiments. The range of lock-in is also reasonably well predicted. Themodified method shows that the influence of non-linear structural damping and stream-wise force components cannot be neglected whilemodelling high mass ratio systems.

Indigenous diagnostic dose of 131I-labeled meta-iodobenzylguanidine ([131I]mIBG) was prepared via Cu+ catalyzed isotope exchange reaction generated in situ by sodium metabisulfite for imaging of neuroblastoma tumor. [131I]mIBG was produced in overall 85-90% radiochemical yield. The average amount of radioactivity of [131I]mIBG was 2164 MBq (1998-2331MBq) with an average specific activity > 1000 MBq/mg at the end of synthesis. The radiochemical purity was ≥ 99.9% after purification through Dowex-1 × 8 ion exchange resin (100-150 mesh) at the date of preparation. The stability of [131I]mIBG at concentration 480-555 MBq/mL was > 97% at 4 °C after 4 days. The room temperature (25 °C) stability of [131I]mIBG was > 98% after 24 h. Biodistribution of [131I]mIBG in patient showed uptake in salivary glands, liver, spleen and excreted though urinary bladder. Neuroendocrine medicated uptake into tumor lesion and metastatic sites were noted which strongly correlate with the morphological abnormalities of patient.
