    Green synthesis of silver nanoparticles by azadirachta indica (neem leaves) and its evaluated effect on maize plant
    (UMT, Lhr, 2024) RIDA ARIF
    In the present study, the silver nanoparticles (AgNPs) were synthesized using the leaf extract of Azadirachta Indica by using quick and environment friendly green synthesis process. The plant extract was used as a reducing and capping agent in formation of nanoparticles. FTIR spectroscopy was used for the characterization of functional groups in the extract in order to identify the specific chemicals contributing to the reduction of silver ions. UV-visible spectrophotometry confirmed AgNPs production by observing an absorbance peak of 410 nm. For the purpose of quantitative analysis, eight, unique, treatments, including synthesized AgNPs, were applied to maize (Zea mays), with each treatment replicated three times. The treatments included: T1 (control with 0% nanoparticles), T2 (10 ppm nanoparticles), T3 (20 ppm nanoparticles), T4 (30 ppm nanoparticles), T5 (urea 10 g + nanoparticles 5 ppm), T6 (urea 20 g + nanoparticles 10 ppm), T7 (urea only), and T8 (seed soaking in nanoparticles overnight). The maize plants were observed for five weeks with respect to a range of growth characteristics, such as vegetation, length of the roots and shoots, total plant weight, reducing and non-reducing sugar content, and levelsof chlorophyll a and b. The treatments that produced the most gains in shoot length, chlorophyll a and b content, and reduced sugar levels were T4 (30 ppm). T7 (urea) showed to be the most successful in raising overall plant weight, whereas T2 (10 ppm) had the longest roots and the highest non-reducing sugar content. These results demonstrate the ability of biosynthesized silver nanoparticles to improve maize development; the 30-ppm treatment exhibited favorable outcomes. This green technology approach's versatility also highlights its potential for sustainability and environmental advantages.

    Working environment
    (UMT.Lahore, 2022) AAMNA IMRAN; RAMSHA NAEEM; SHAHZADI RAZIA SULTANA; RIDA ARIF
    The study was conducted to explore the relationship between working environment, empathic concern and professional quality of life among female staff nurses. It was hypothesized that 1) there is likely to be a relationship between working environment, empathic concern and professional quality of life among female staff nurses and 2) Working environment and empathic concern are likely to predict professional quality of life among female staff nurses. The correlational research design was used in the present study. About 190 nurses with age range of 19-58 years (M = 30.79, SD = 7.34) from different hospitals in Lahore including Jinnah Hospital, Sir Ganga Ram Hospital, Govt. Mozanag Hospital and Sheikh Zayed Hospital were approached. The self-constructed demographic sheet, Working Environment Scale (Rossberg et al., 2004), empathic concern subscale of Interpersonal Reactivity Index (Davis, 1983) and Professional Quality of Life scale (Stamm, 2010) were used for assessment. The results of Pearson Product Moment Correlation analysis concluded that self-realization is positively associated with empathic concern and compassion satisfaction among nurses. Further, it was found that workload in work environment is also positively associated with secondary traumatic stress. Further, conflict and nervousness and in the hospital environment is positively associated with burnout and secondary traumatic stress. Results of Multiple Hierarchical Regression analyses showed that self-realization positively predicted compassion satisfaction but negatively predicted burnout among female staff nurses. Further, conflict and nervousness in work environment positively predicted secondary traumatic stress and positively predicted burnout. This study is useful to highlight the factors that affect professional quality of life of nurses and linking with their burnout and secondary traumatic stress. This study can also be used in devising strategies to improve xii quality of work environment in hospitals influencing quality of life of healthcare profession system and to devise strategies to help improve the professional quality of life of nurses.
