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.

Purpose: The objective of the study is to examine the role of approval goals, subjective norm, internal motivation, external motivation, attitude towards behavior, and perceived behavioral control on retail consumer’s intention to consume fortified food in Pakistan. Research design, data, and methodology: The study was quantitative in nature. That is why the data were collected from 384 respondents approaching retail stores of Lahore, Gujranwala, and Faisalabad using mall intercept survey. Partial least squares structural equation modeling (PLS-SEM) was used to analyze the data. Results: The results show that approval goals significantly influence subjective norms. Secondly, subjective norms positively influence internal and external motivation. Thirdly, attitude towards behavior and internal motivation significantly impacted on intention. However, the findings of the study show, non-significant relationship of external motivation and perceived behavioral control with intention to consume fortified food. Conclusion: Theory of reasoned goal pursuit was used to investigate consumer intention to consume fortified food in Pakistan. This study is helpful for the marketers to create a word-of-mouth strategy to enhance positive word of mouth for the company, which ultimately beneficial to develop the distribution strategy of the firm. Fortified food is full of health enriched ingredients which is beneficial for society at large.

Tomatoes are a major crop for global exports and have significant nutritional benefits. However, their lifespan is limited due to various biotic and abiotic factors. This study aimed to formulate an edible coating using crude alfalfa saponins coupled with decaglycerol monolaurate (ML-750) and polyoxyethylene (20) sorbitan monolaurate (Tween 20), to enhance the postharvest quality and shelf life of tomatoes by preventing spoilage. The effectiveness of alfalfa saponins coatings, both alone, and with ML-750 and Tween 20, was evaluated by comparing their impact on color, texture, overall acceptability, and % weight loss at 4°C and 25°C for 7 days. Significant improvements were observed in the quality attributes of tomatoes, including firmness, aroma, color, texture, and overall acceptability. Crude alfalfa saponins in emulsified form with Tween 20 increased the shelf stability of tomatoes more effectively than uncoated and ML-750 combined coatings. The total soluble solids (TSS) and pH also play a crucial role in determining the quality of the fruits. The results indicated no significant changes in the TSS of tomatoes coated with encapsulated saponins. Subsequently, a gradual increase in the pH of the coated tomatoes was observed on days 5 and 7, respectively. The findings of this study revealed that alfalfa saponins coupled with synthetic emulsifiers may be a beneficial strategy for prolonging the shelf life and improving the postharvest quality of tomatoes.
Three-dimensional atomic force microscopy for ultra-high-aspect-ratio imaging
Akhtar, Imtisal,Rehman, Malik Abdul,Choi, Woosuk,Kumar, Sunil,Lee, Neasung,Cho, Sang-Joon,Park, Hyeong-Ho,Park, Kyung-Ho,Seo, Yongho Elsevier 2019 APPLIED SURFACE SCIENCE - Vol.469 No.-
<P><B>Abstract</B></P> <P>Three-dimensional (3D) imaging of nanostructures with high aspect ratio features is a challenging problem of broad relevance to nanoscience and nanotechnology. Though a wide variety of experimental strategies to improve 3D imaging capabilities have been proposed, current measurement capabilities are mainly limited to imaging deep trenches, in large part due to the lack of truly 3D scanning algorithms and limited dynamic control of the tilt angle. Herein, we report a non-contact atomic force microscope (AFM) strategy that overcomes these challenges by employing an intelligent 3D scanning algorithm that combines sidewall detection and real-time adjustment of the probe’s direction. To test this approach, we measured the depth and sidewall topography of porous anodic aluminum oxide (trench), via holes and silicon nanopillar (protrusion) with precision tracing. Using a carbon nanotube-based AFM probe, it was possible to measure the depth of holes with an aspect ratio of 5.9. In addition to this, we have successfully achieved the 3D image of via holes with an aspect ratio of 4.3 and a resolution of 2 nm, which enables realistic profiling of the sidewall and bottom edge of holes. Taken together, our findings demonstrate how the intelligent scanning algorithm based on detection-and-decision with a high-aspect-ratio probe can be utilized as a broadly applicable nanoscience measurement tool to characterize 3D topographical features of nanostructures.</P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

A well known Ayurvedic formulation Ashokarista, used for menstrual disorders has been studied in a single blind randomised placebo controlled clinical trial for the treatment of menorrhagia and dysmenorrhoea. Dysmenorrhoea and menorrhagia patients who were taking Ashokarista (20 ml twice daily) for 10 menstrual cycles had an increase in haemoglobin level. Menorrhagia treated group has shown to reduce the erythrocyte sedimentation rate level that has been increased in the menorrhagia control group. The platelet count, total count and differential count were observed unchanged in the study. The Ashokarista did not affect the SGPT and SGOT level, which signify its lack of toxicity in hepatic function. The treated menorrhagic patients showed an increase in serum albumin content and decrease in blood clotting time, whereas the serum protein content was observed unchanged. There was a significant increase in both serum cholesterol and triglyceride level, which usually associated with the use of oral contraceptives. No major side effects were observed by the clinicians during the study.

Studies were conducted to identify the sources of resistance in mungbean recombinant inbred lines (RILs) in Thailand against mungbean yellow mosaic disease (MYMD). 146 mungbean RILs in $F_8$ series were evaluated in a field including resistant parent NM-10-12-1 and susceptible parent KPS 2 during summer 2008 under high inoculum pressure. The RILs were subsequently scored for disease symptom severity ratings (DSSR) using a new scale. Observations regarding DSSR and % disease index (%DI) showed that the tested RILs responded differently to the disease. A large number of RILs (132) were found highly susceptible, 12 were susceptible, 3 were tolerant and one was resistant. Overall screening results showed that three RILs, viz. line no. 30, 100 and 101 had minimum DSSR and % disease index thus they are good source of resistance to MYMD in spite of high disease pressure and can therefore be used directly as varieties to manage the disease in Thailand.

The present study was carried out to investigate the serum minerals profile in buffaloes (Bubalus bubalis) suffering from parturient haemoglobinuria (PHU) along with minerals profile of soils and fodders from the disease prone areas and their interrelationships. Serum samples were collected from 60 each of healthy and PHU affected buffaloes randomly selected from field cases. Serum samples were collected from each animal. Fifty composite soil samples were collected where PHU was prevalent. Fifty samples of fodders including leaves and stems being fed to the diseased buffaloes were collected. The difference in the levels of calcium and potassium between upper and lower soil surface of disease prone areas under study were statistically non-significant. The mean values of phosphorous, copper, iron, selenium and molybdenum in upper soil surface were significantly (p<0.05) higher than in lower soil surface. None of the fodders offered to the diseased animals met the dietary requirements of phosphorus and copper whereas none of the fodders was deficient in potassium, iron and selenium rather were having excess of potassium, iron and selenium. The concentration of calcium was adequate in lucerne, berseem, sarson and sorghum, while maize, sugarcane and wheat straw did not meet the required levels for dairy animals. Molybdenum contents in all fodders were adequate to meet the dietary requirements of the dairy buffaloes. Serum phosphorus, copper and selenium were significantly (p<0.001) lower whereas potassium, iron and molybdenum in buffaloes suffering from PHU were significantly (p<0.001) higher than in healthy buffaloes. It was concluded that phosphorous deficient soils play a major role by transferring this deficiency to plants and ultimately reaching to animals where hypophosphataemia is a consistent finding.
