“…The findings show the average number of women in Central Punjab is higher (4.09) than in Southern Punjab (3.78) and High Punjab (3.64), on average. In addition, access to school, health care, work prospects are higher in central Punjab(Irfan et al, 2019).The present study endorses social mobility as an essential feature of women's socio-cultural ability indicators(Bespinar, 2010). The experiments have been maintained in line with(Jejeebhoy & Sathar 2001;Khan & Maan, 2008).…”

Purpose of the study: This study intends to demonstrate the importance of sub-provincial variation in women empowerment in Punjab, Pakistan. Methodology: The study used the Cumulative Women Empowerment Index (CWEMI) for three regions of Punjab Pakistan, using primary data of 950 respondents. The data is obtained through multistage stratified cluster sampling techniques from Upper, Central, and Southern Punjab based on the prevalence of female literacy rate. The statistical technique namely Multivariate Analysis of Variance (MANOVA) and Analysis of Variance (ANOVA) has been used to make the comparison on a regional and dimensional basis. Main Findings: The result of the study shows that there exits substantial sub-provincial variation in upper, central, and southern Punjab regarding different domains of women empowerment. Applications of this study: This study identifies the regional diversity in women empowerment in Punjab, Pakistan. The results of the study provide guidelines to the policymakers in formulating appropriate policies for eliminating diversity in women empowerment in different regions of Punjab, Pakistan. Novelty/Originality of this Study: Improvement in women empowerment is regarded as an essential human right and sustainable development goals that needs appropriate monitoring. The majority of previous studies have tried to measure women's empowerment through developing several indices but these indices appear insufficient to meet the international standards. The present study is an attempt to track multiple domains of women empowerment through CWEMI. The results of the study may bring up a status of women empowerment across different regions of Punjab, Pakistan.

“…However the characteristic peak of PVA was suppressed by the addition of PVP, and a further shift was observed in the case of CMC addition. CMC generally exhibits its characteristic peak at 22° [ 50 ] while PVP exhibits its characteristic peak at 21.84° [ 51 ]. It was observed that addition of CMC caused a slight shift in peak towards 21–22°, which shows the dominance of CMC is tricomponent composite nanofibers.…”

Cellulose is one of the most abundantly available natural polymers. Carboxymethyl cellulose (CMC) belongs to the cellulose family and has different degrees of substitution. Current research comprises the fabrication and characterization of CMC nanofibers using polyvinyl alcohol (PVA) and polyvinylpyrrolidone (PVP) as capping agents and carriers for sustainable food packaging applications. Recently authors successfully fabricated smooth and uniform nanofibers of stated polymers and optimized the ratios of three polymers for continuous production. However, in this research, it was further characterized for mechanical properties, surface properties, structural properties, air permeability, and chemical properties to confirm the suitability and scope of tri-component nanofibrous mats in food packaging applications. Different fruits and vegetables were packed in a plastic container and closed by nanofiber mats and by a plastic lid. All samples were observed after a specific period of time (fruits were kept for 40 days while vegetables were kept for 10 days in the controlled environment). It was observed in the results that fruits and vegetables closed by nanofiber based webs exhibited better freshness and lower accumulation of moisture as compared to that of containers with plastic lids. From the results of performed tests, it was observed that nanofiber mats possess enough mechanical, structural, and morphological properties to be used as food packaging.

“…ICPs were investigated as the active material of flexible strain sensor. Because ICPs are conductive materials, their blends with a soft or elastic polymer can show a resistance sensitive to the tensile strain 102,150–153 . However, a normal ICP films on a flexible substrate usually exhibit a resistance not very sensitive to the tensile strains.…”

Intrinsically conducting polymers (ICPs), such as polyacetylene, polyaniline, polypyrrole, polythiophene, and poly(3,4‐ethylenedioxythiophene) (PEDOT), can have important application in flexible electronics owing to their unique merits including high conductivity, high mechanical flexibility, low cost, and good biocompatibility. The requirements for their application in flexible electronics include high conductivity and appropriate mechanical properties. The conductivity of some ICPs can be enhanced through a postpolymerization treatment, the so‐called “secondary doping.” A conducting polymer film with high conductivity can be used as flexible electrode and even as flexible transparent electrode of optoelectronic devices. The application of ICPs as stretchable electrode requires high mechanical stretchability. The mechanical stretchability of ICPs can be improved through blending with a soft polymer or plasticization. Because of their good biocompatibility, ICPs can be modified as dry electrode for biopotential monitoring and neural interface. In addition, ICPs can be used as the active material of strain sensors for healthcare monitoring, and they can be adopted to monitor food processing, such as the fermentation, steaming, storage, and refreshing of starch‐based food because of the resistance variation caused by the food volume change. All these applications of ICPs are covered in this review article.
