This is part of a study investigating the structural properties of blocks produced from using different combination of laterite and quarry dust as full replacement for conventional river sand as aggregate. The use of alternative materials in blocks production and other concrete works is becoming increasingly popular across most developing countries. This work developed a mathematical model using Osadebe Regression Theory (ORT) for the prediction of cost/cum of laterite- quarry dust cement block. The lack of fit of the model was carried out using statistical tool (excel) and found to be adequate. The model will be very useful especially for commercial blocks producers and built experts in Nigeria and sub-Sahara African countries for construction cost estimation and profit projection.

In this study, it can be found that domestic electrical engineering scholars have the following problems in writing abstracts: overuse of nominalization, underuse of the verbalization of conjunction, insufficient use of some types and low lexical variation.

Introduction: The objective was to study chronic pathologies associated with severe acute malnutrition in children aged 6 to 59 months hospitalized at URENI. Methodology: This was a retrospective, descriptive and analytical study running from January 1 to December 31, 2017. Results: During the study period 352 children were hospitalized for severe acute malnutrition at the URENI of the CSREF CV. Among them, 18 presented a chronic pathology, i.e. a frequency of 5.11%. The male gender was predominant, i.e. 61.1% with a sex ratio of 1.57. The 12-24 month age group represented 50% of cases. Thirty-three percent of children had a history of neonatal resuscitation and 16.7% were formerly premature babies. Marasmus was of the severe acute malnutrition type the most represented, i.e. 77.8% of the cases. The association of malnutrition with HIV infection and Cerebral Palsy (CP) were accounted for 27.8% each. More than half of the patients (55.6%) stayed between 15 - 21 days in the structure. Conclusion: HIV infection and cerebral palsy constitute the chronic pathologies most associated with severe acute malnutrition in children at the Csref of commune V.

Primary factors considered that influence inflation movement can experience significant changes due to the COVID-19 pandemic. This research focuses on examining macroeconomic factors which influence the inflation rate in Saudi Arabia which is critical for development and adjusting a suitable policy response. Saudi Arabia’s changing inflation trends are also affected by its internal and external factors including domestic demands, net spending of Government, and liquidity along with exchange rate movements and imported inflation. This research paper focuses on providing insights regarding previous studies conducted on this topic by adopting different approaches. The approach utilized in this study reflects mainly non-oil revenues like value-added tax along with levies related to expatriates on inflation. ARDL (Autoregressive Distribution Lag Model) has been applied instead of the Vector Error Correction model considering its robustness for 40 quarter sample sized integrated in this study. From the results, it has been confirmed that the inflation Movement in Saudi Arabia is more inclined to external factors than domestic factors.

Agroforestry, the integration of trees with agricultural or livestock systems, holds significant promise for sustainable land management and addressing various environmental challenges. This comprehensive review explores the multifaceted benefits and challenges associated with agroforestry systems, focusing on their interactions with agronomy crops. We delve into the ecological, socio-economic, and climate-related dimensions of agroforestry, highlighting its potential to enhance productivity, conserve resources, and mitigate climate change impacts. The review begins by examining the historical context and conceptual foundations of agroforestry, elucidating its diverse array of products and services. Through case studies and empirical research, we explore the ecological benefits of integrating trees with crop production, emphasizing improvements in soil fertility, water quality, and biodiversity conservation. Furthermore, we discuss the role of agroforestry in climate change adaptation and mitigation, including its capacity for carbon sequestration, soil restoration, and resilience-building in the face of extreme weather events. A critical analysis of agroforestry's implications for agronomy crops reveals both opportunities and challenges. While agroforestry systems have shown potential to enhance crop yields, improve soil health, and diversify income sources, they also present complexities related to competition for resources and management practices. Insights from studies conducted in various agro-ecological contexts provide valuable guidance for optimizing the design and implementation of agroforestry systems to maximize their benefits for agronomy crops. This review underscores the importance of interdisciplinary collaboration and knowledge exchange in advancing agroforestry research and practice. By integrating principles from agronomy, ecology, economics, and forestry, we can develop innovative strategies to harness the full potential of agroforestry for sustainable agriculture and environmental conservation.

Rice, as a staple food for more than half of the world's population, plays a crucial role in global food security. However, weed competition poses a significant challenge to rice cultivation, affecting yield and quality. To address this challenge, rice farmers have increasingly turned to chemical herbicides as a cost-effective alternative to labor-intensive manual weeding. This review paper explores the current practices and future directions in herbicide strategies for weed control in rice cultivation, with a specific focus on diverse approaches adopted in various agro-ecological regions, particularly in Pakistan. The paper begins by highlighting the importance of rice cultivation in global agriculture and the economic significance of the crop, emphasizing the need for effective weed management to ensure sustainable production. It discusses the impact of labor shortages and rising labor costs on weed control practices, driving the adoption of chemical herbicides, especially in direct-seeded rice cultivation. Additionally, the review underscores the importance of integrated weed management systems, which combine cultural practices, targeted herbicide applications, and legislative measures to optimize crop productivity while minimizing environmental impact. Furthermore, the paper evaluates the efficacy of different herbicides and their timing of application in managing weeds and maximizing rice yield. It synthesizes findings from recent studies to provide insights into the effectiveness of pre-emergence and post-emergence herbicides, as well as their impact on weed-crop competition and overall crop health. By analyzing the strengths and limitations of existing herbicide strategies, the review identifies opportunities for innovation and improvement in weed management practices.
