Published: October 2023

Natural gas production from tight and impermeable shale formations can be recognized as shale gas and has developed into a significant source of natural gas globally. With the development of modern technology, natural gas prices are likely to rise rapidly in response to substantial supply and demand pressures. The gross thickness of the Ranikot Group in the Lower Indus Basin ranges from 100 m to 400 m. The Ranikot Group is nearly 300 meters thick in the studied area having a depth of more than 1000 m to 2000 m. Geochemical studies indicate that the TOC content analyzed in specimens varies in range from 0.69-8.5 wt. % and the average value is about 2.30 wt%. Hydrogen Index ranges from 40-250 mg HC/g, hence, exhibiting the type III kerogen, which is also corroborated by the Van Krevelen diagram and shows a tendency to generate the gaseous hydrocarbons. The studied samples' Production Index (PI.) is between 0.02-26.2, averaging2.41 mg HC/g rock. Tmax varies from 420 to 444 oC, and Vitrinite Reflectance (R o) is between 0.4-0.8%, indicating that the organic matter in the shales of RaniKot Group is immature to early mature. In the studied shale intervals of the Ranikot Group, the clay (ductile mineral) content ranges from 20-30%, while brittle mineral content (quartz) ranges from 70-80%. High Brittleness Index, value (0.6 -Average), lesser values of Poison Raito, and higher values of Young's Modulus reveal that Ranikot Group's shales are within the brittle region. Studied samples of Ranikot Group were mostly brittle. Therefore, it is suggested that the formation is suitable for hydraulic fracturing.

Published: October 2023

Biofouling is amongst the paramount complications in membrane filtration systems, which are used to purify wastewater. It increases the price tag on processes, whereas decreases the membrane permeability and period efficiency. Utilizing the strong attributes of silver nanoparticles (AgNPs) as antibacterial agents, mycological originated AgNPs were evaluated in the study. Development of polysulfone membrane (Psf) infused with AgNPs for wastewater treatment, having antibacterial along with antifouling properties were included in the study. Several water-drainage microbial insulates, e.g, Enterobacter aerogenes, Escherichia coli, Klebsiella pneumonia, Salmonella choleraesuis, Shigella sonnei, Pseudomonas aeruginosa, and Staphylococcus aureus appeared to be restrained against AgNPs of concentration 50-500 ppm. The AgNPs impregnated Psf ultrafiltration membranes reduced the bacterial count (cfu/cm2) at the 7th, 21st, 30th and 45th day of experimentation in contrast to standard Psf membrane. The efficacy of this anti-biofouling was confirmed by employing FTIR and scanning electron microscopy (SEM) characterization techniques. Within FTIR, in addition to characteristic highs of Psf layer, a new top at 687 cm-1 showing a -CH=CH- pattern in the cis transfiguration was also present, proving the particular degradation of membrane on account of biofouling. The SEM images confirmed that AgNPs tried their best to hinder biofouling, hence, AgNPs proved to be a beneficial solution for restraining the biofilm expansion and increasing membrane life.

Authors: KHAN SAJIDA , KHAN YASIR , ALI IFTIKHAR
Published: October 2023

Mutual Funds enable small investors to benefit from the capital market with minimal investments, thanks to the expertise of professional managers. This study focuses on the Pakistani Mutual Fund industry and evaluates the suitability of traditional and multifactor asset pricing models in assessing Mutual Fund performance. Since multifactor models are rarely used in Pakistani research, this study employs the CAPM, Fama French, and Carhart models to assess the performance of Pakistan Mutual Funds. Data from 100 open-end Mutual Funds between 2005 and 2017 was collected from the Mutual Fund Association of Pakistan, while risk-free rates data was gathered from the State Bank of Pakistan and stock data from the Pakistan Stock Exchange. Ratio analysis, CAPM, Fama French-3 Factor, and Carhart-4 Factor models were used to analyze the data and determine which model was most suitable. The results indicate that the CAPM affects the market factors of the majority of portfolios. Conversely, the size factor, value factor, and momentum factor in the Fama French and Carhart models have an insignificant effect on the majority of portfolios. The Gibbon Rose Shanken test reveals that the CAPM model is the most suitable for evaluating Mutual Fund performance in Pakistan. The findings of this study have implications for asset management company managers and investors alike. It provides valuable insights into which funds perform better and which types of funds are ideal for investment.

Understanding the Influencing Mechanism of Users’ Purchase Intention and Mediating Effect of Trust in Streamer: A Socio-Technical Perspective
Authors: Zhang Yifei , Ahmad Albattat , Azman Norhidayah , Mingxia Wei
Published: October 2023

Purpose This study primarily aims to investigate the role of trust in the streamer in the formation path of purchase intention and the influencing factors of both trust in the streamer and purchase intention.
 
Theoretical framework: Given that live streaming e-commerce possesses strong social attributes and requires technological means to facilitate remote social interactions, we have chosen to adopt the socio-technical theory as the theoretical foundation for this study.
 
Design/methodology/approach: This study employs an empirical research approach and utilizes random sampling to distribute questionnaires to users of the Douyin platform. We select users who have an intention to purchase or have prior purchasing experience on the live streaming platform for our survey.
 
Findings: According to the findings of the study, identification, two-way communication, and visibility have a significant impact on purchase intention. Trust in the streamer serves as a mediating factor in the relationship between these three variables and purchase intention. Synchronization cannot directly influence purchase intention and cannot impact purchase intention through trust in streamer either.
 
Research, practical & social implications: For theoretical implications, prior research rarely delved into how trust in a streamer affects purchase intention. This study addresses this gap and helps researchers explore this field further. It explores the role of trust in streamer in shaping purchase intention, also offering practical strategies for retailers to enhance trust.
 
Originality /value: This study innovates by breaking down trust into trust in the streamer to examine its impact on purchase intention formation. Future research can explore trust from different perspectives, offering new insights into trust in live streaming commerce.

Authors: Mekaunint Tigist Firew , Degu Hewan Demissie , Yayis Rezene
Published: October 2023

Common bean (Phaseolus vulgaris L.) is one of the significant grains used in the human diet, accounting for half of all grain legumes consumed globally. To enhance production, conventional breeding and molecular approaches have been used so far. An efficient and rapid genomic DNA extraction method is required for these molecular approaches. The aim of this study was to compare and optimize an efficient and rapid DNA extraction protocol for common bean. Modified cetyl trimethylammonium bromide (CTAB) and potassium chloride (KCL) extraction methods were used. The mean DNA yield per nanoliter was 209 µg from modified CTAB and 150.3 µg from the KCL method. The concentration of gDNA was significantly (P< 0.05) higher for the KCL method, which was 5.01 µg/µl and 2.09 µg/µl for the CTAB method. The obtained DNA was also pure, with an absorbance ratio at 260 nm to an absorbance of 280 nm (A260/280) of 1.75-2.23 for the KCL method and 1.86-2.09 for the modified CTAB method. Gel electrophoresis separation was used to evaluate the quality of the total DNA extracted by the present protocols. The results showed that intense bands close to the gel wells were obtained from both extraction methods. DNA isolated with the two methods was successfully used for PCR-based downstream analysis, which includes random amplified polymorphic DNA (RAPD) and simple sequence repeat (SSR) markers. In this study, it took approximately 150 minutes for KCL and 240 minutes for the CTAB for whole process. In contrast to the CTAB method, the KCL method uses inexpensive and less hazardous reagents and requires only ordinary laboratory equipment. Therefore, it is more convenient and economical than the traditional technique.

Published: October 2023

Turkey breeder hens (200) and viable toms (24) of 30–35 weeks of age of small white variety were distributed into 2 treatment groups having 4 replicates of 25 hens and 3 toms in each treatment. First four replicates were offered turkey breeder diet (diet A) (NRC 1994) and other 4 replicates were offered high immune diet (diet B) having 115% amino acids, 1% each omega-6 and omega-3 fatty acids, retinol- 4.95 mg, DL-a-tocopherol- 199.86 mg, ascorbic acid –150 mg, selenium- 0.5 mg and zinc–118 mg / kg diet for 8 week duration. After 6 weeks of experimental feeding, 2 replicates from each treatment groups were vaccinated with ND (R2B) vaccine. Average egg weight of birds fed diet B was significantly higher after 6 weeks of experimental feeding than diet A. Per cent fertility and per cent hatchability on total egg set basis was better in the birds fed diet B than diet A. Chicks hatched from the birds fed diet B were heavier than the birds fed diet A. Total immunoglobulins, IgG and IgM response to sheep red blood cells were also higher in the diet B than diet A. Birds fed diet B had better cell-mediated immune response than birds fed diet A. Birds fed diet B had significantly higher HI titer against R2B vaccination than those fed diet A at 7 days post vaccination. Hence, it may be concluded that turkey breeders may be fed high immune diet to enhance egg weight, chick weight, fertility, hatchability and immune response.

Cultural Imaginary of Terrorism: Close and Distant Readings of Political Terror in Swedish News and Fiction During the Cold War
Authors: Fridlund Mats , Michael Azar , Brodén Daniel , Michael McGuire
Published: October 2023

The digital history project ’The Cultural Imaginary of Terrorism’ (2022–2025) examines the cultural meaning-making of political terror in Swedish nonfiction and fiction during the Cold War, a critical period for the formation of the international discourse on terrorism. To explore the Swedish ‘cultural imaginary of terrorism’ is to study how a society makes sense of terrorism and itself in relation to the phenomenon through figures of thought, frames of reference and fantasies in, among other things, national newspapers and periodicals. This paper gives an overview of the project, demonstrating our integrative use of distant and close reading methods through a pilot study of elements of the cultural imaginary of terrorism as represented in the conservative periodical Svensk Tidskrift 1945–1991. Our exploratory analysis focuses on the extraction of relevant texts, the visualization and mapping of the discourse through the development of key terms as well as individuals, places, groups and states associated with political terror and terrorism. We conclude by stressing the benefits of an integrative research design drawing upon complementary perspectives: how our text mining methods allow us to identify significant patterns in the text data and how our historical expertise allows us to single out aspects that call for further investigation.

Introduction: technologies have increasing availability and significance in health care. Self-care tools are promoting “positive medicalization” by enabling patients to reclaim their individual agency in health care. In Type 1 Diabetes treatment, health technology is prominent - Continuous Glucose Monitoring (CGM) has been developed to facilitate management of the disease, while easing the emotional burden. Objective: the objective of the study was to show how technology-led self-care affects individuals, and more specifically, their relationship with their doctor, when they gain agency over their own health care.Methods: this paper draws on a quantitative study using data from the Jaeb Center for Health Research (USA); it examines the effects of CGM on patients’ everyday lives right after starting the use, and after 6 and 12 months of use. The data also shed light on the role of CGM in reshaping patient-doctor relationships. ANOVA tests and binary logistic regression analysis were conducted (n=451, female: 55 %, male: 45 %, age: mean 25,04, SD 15,8).Results: the use of the CGM gives freedom to users, but the CGM causes hassles in their daily lives after 6 months of use. Socio-demographic factors (education level, gender, age) did not play a significant role in the changing patient–doctor relationship.Conclusion: despite the burden technology may cause, CGM seems beneficial by easing diabetes management. Regarding the patient-doctor relationship, users seemed unaware of changes despite the great gain in agency. This case offers a way to shift the focus to a more moderate critique of medicalized technologies

Năm 1952, Tiến sĩ Ogden Bruton lần đầu tiên báo cáo một trường hợp cậu bé 8 tuổi bị nhiễm trùng huyết tái phát do vi khuẩn, viêm tủy xương và viêm tai giữa, do thiếu một phần gamma globulin và không thể tạo ra kháng thể. Bệnh sau đó được mô tả là liên kết X agammaglobulinemia (XLA), biểu hiện bằng giảm globulin miễn dịch trong huyết thanh và số lượng tế bào B giảm rõ rệt trong máu ngoại vi. Sau đó, năm 1993, các đột biến của gen mã hóa tyrosine kinase, được đặt tên là Bruton’s tyrosine kinase (BTK), đã được xác định. Bệnh nhân XLA có quần thể tế bào tiền B bình thường trong tủy xương nhưng các tế bào này không thể trưởng thành và di chuyển trong máu ngoại vi. Gen mã hóa BTK nằm trên NST X (Xq21.3-q22). Đã có hơn 400 đột biến gen BTK được phát hiện, trong đó có ít nhất 212 đột biến liên quan đến các bệnh đã biết.
Intermediate Technologies: The Key to Eradicating Post-harvest Losses (PHLs) in Sub-Saharan Africa (SSA)
Authors: Mayanja Ismael K. , Oluk Isaac
Published: October 2023

Post-harvest losses (PHLs) in Sub-Saharan Africa (SSA) pose a significant threat to food security and economic stability. PHLs account for a substantial portion of food waste and economic losses. This paper explores the potential of intermediate technologies in addressing this challenge. Intermediate technologies, including hand-operated, pedal-operated, and solar-powered devices, offer adaptable and cost-effective solutions tailored to the needs of smallholder farmers who make up the majority of SSA's agricultural sector. These technologies bridge the gap between labor-intensive traditional methods and high-end, expensive equipment. They enhance efficiency, reduce labor, and have the potential to revolutionize post-harvest processes. Additionally, emerging innovations, such as harnessing energy from footsteps and raindrop energy offer promising avenues for further enhancing the sustainability and efficiency of post-harvest operations in resource-constrained environments. Intermediate technologies represent not only tools but also catalysts for transformation. They hold the key to reducing PHLs, fostering economic growth, ensuring food security, and leading to sustainable agriculture in SSA. By harnessing these technologies' adaptability and resource efficiency, SSA can move closer to a more sustainable and prosperous future.
Unitary Caring Science: Caritas Compassion Transpersonal Theory
Authors: Watson Jean
Published: October 2023

This article presents a transformative perspective on contemporary nursing, emphasizing unity and interconnectedness in the post-Covid world. Prof. Jean Watson introduces "Unitary Caring Science" as a holistic approach to nursing, rooted in three ethical principles: The Ethic of Belonging, The Ethics of Face, and The Ethics of Hands. These principles guide the paradigm shift in nursing philosophy and practice. Dr. Watson discusses the "Ten Caritas Processes®," a foundational language for understanding and practicing human care. She highlights the importance of "Transpersonal Caring Moments," where nurses' presence and authenticity influence patient experiences. The article aligns this approach with the American Nurses Association's new definition, emphasizing compassion and presence in nursing care, and advocates for a holistic, interconnected nursing approach to uphold human dignity and compassion.

Heterosis and combining ability study for yield and quality traitsin castor [Ricinus communis(L.)]" was carried out through diallel analysis at Main Castor-Mustard Research Station, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar. The experimental material composed of 45 hybrids, 10 parents and standard check GCH 5.The analysis of variance showed highly significant differences among genotypes and hybridsfor all the traits. Parents also differed significantly for all the charactersindicating considerable amount of genetic variability present in the experimental material. The average performance of hybrids differed from that of the parents for days to flowering, daysto maturity,seed yield /plant, oil content in seed and oil content in endosperm. Exploitable heterosis for seed yield/plant was observed in crosses HC 8 x 37504 (155.2%), PRT 44 x 37504 (99.1%), 37504 x 37500 (86.8%) and SKI 1 x 37500 (79.5%), whereas, cross HC 8 x 37504 (149.8%) and PRT 44 x 37504 (86.2%) recorded high heterobeltiosis for seed yield/plant. Crosses showing heterosis for seed yield exhibited noticeable heterosisthrough important yield components like days to maturity, days to flowering, stem length, oil content in endosperm and oil content in seed. The analysis of variance for combining ability showed highly significant differences for all the traits under investigation. The predictability showed that non-additive gene action was primarily involved in the inheritance ofthe characters viz., daysto flowering, daysto maturity,seed yield/plant, oil content in seed, endosperm content and oil content in endosperm. Additive gene action was found predominant for stem length, number of effective branches/plant and 100 seed weight. The parent, 37504 was a good combiner for seed yield/plant, while SKI-1 proved good combiner for oil content in seed. The ranking of parents based on gca effects was almost similar to that based on per se performance for most of the characters. Two hybrids SKI-1 x 37500 and HC-8 x 37504 exhibited significant and positive sca effects for seed yield per/plant. The cross HC-8 x 37504 gave highest seed yield/plant which had poor x good general combining parents.

Published: October 2023

Association and path coefficient analysis was computed on 64 genotypes of sunflower (Helianthus annuus L.). Seed yield was positively correlated with number of filled seeds/head, total number of seeds/head, seed filling per cent, plant height and 100 seed weight. Selection based on number of filed seeds/head, total seeds/head and seed filling percent would increase seed yield. Path analysisindicated that number of filled seeds/head had the maximum direct effect followed by 100 seed weight, total seeds/head and seed filling per cent.

Published: October 2023

Thirty single cross sunflower (Helianthus annuus L.) hybrids produced were subjected to mid parent, better parent and standard heterosisstudies using three checks, viz., KBSH 1, KBSH 44 and GK 2002. The cross CMS 234 A x RHA-95-C-1 recorded the highest heterosis of 104.01% over better parent for seed yield which was followed by CMS 234 A x RHA-6D-1 and CMS 234 A x RHA-271 with 86.06 and 85.15%, respectively. None of the experimental hybrids could surpass the standard heterosis over checks KBSH-1 and GK 2002 for seed yield and oil content. However, three hybrids CMS 17 A x RHA-6D-1 (13.82), DCMS 51 A x R-298 (12.85), DCMS 51 A x RHA-272 (9.81) and 18 crosses where RHA-6D-1 and RHA-271 were used as male parents in combination with CMS 234 A, CMS 4546 A and DCMS 51 A showed significant heterosis over the check KBSH-44 for seed yield and oil content, respectively. The highest heterosis in the cross CMS 234 A x RHA-95-C-1 can be assigned to contribution of heterosis from component characters such as hull content, per cent seed filling and number of filled seeds/head.
