The growing demand for fresh vegetables has necessitated larger production and the substantial production of vegetables within the shortest possible time to meet the ever-increasing demand has placed them at a higher risk of contamination with the pathogenic microbes, making the safety of consumers uncertain. This study aimed to discover the fungal species found on the surface of green leafy vegetables and their implications on consumers' health. Four (4) species of green leafy vegetables (GLV) which include; waterleaf (Talinum fruticosum (L.) Juss.), African basil (Ocimum gratissimum L.), green amaranth (Amaranthus viridis L.) and fluted pumpkin leaves (Telfairia occidentalis Hook.f.) were randomly purchased from different parts of Bwari market in Abuja, Nigeria and analyzed using pour plate method. The studies discovered four different fungal species, including Aspergillus spp, Candida albicans, Rhizopus spp, and Penicillium spp. This confirmed that microorganisms naturally occur in every environment and can get food products contaminated. Since some of them are pathogenic, unhygienic handling of those vegetables can cause severe health effects on humans. Several measures have given positive hopes in controlling contamination caused by microbes which include washing vegetables with vinegar water. Washing vegetables with saltwater is also effective but adequate precautionary measures are necessary which include ensuring that the same water is not used to wash different vegetables from different sources that could be carrying different microbes.
随着人们对新鲜蔬菜需求的不断增长，蔬菜生产量也随之增大，而在最短时间内大量生产蔬菜以满足日益增长的需求，使蔬菜受到病原微生物污染的风险增加，从而使消费者的安全受到威胁。本研究旨在发现绿叶蔬菜表面的真菌种类及其对消费者健康的影响。研究人员从尼日利亚阿布贾布瓦里市场的不同地方随机购买了四（4）种绿叶蔬菜（GLV），包括：水叶（Talinum fruticosum (L.) Juss.）、非洲罗勒（Ocimum gratissimum L.）、绿苋菜（Amaranthus viridis L.）和凹槽南瓜叶（Telfairia occidentalis Hook.f.），并采用倒平板法进行了分析。研究发现了四种不同的真菌，包括曲霉菌属、白色念珠菌属、根霉菌属和青霉菌属。由于其中一些微生物具有致病性，不卫生地处理这些蔬菜会对人类健康造成严重影响。一些措施为控制微生物污染带来了希望，其中包括用醋水清洗蔬菜。用盐水清洗蔬菜也很有效，但必须采取适当的预防措施，包括确保不使用同一种水清洗不同来源的蔬菜，因为不同来源的蔬菜可能携带不同的微生物。

Emptying, transportation and disposal of faecal sludge in informal settlements of Eldoret Kenya is still a big challenge. This study aimed to identifying actors and factors determining emptying costs and constraints limiting improvement in service provision with the use of a questionnaire and a review of secondary data. A total of 35 respondents were issued questionnaires. The data showed that most of the households were using septic tanks as the preferred method of Onsite Sanitation Systems (OSS). The study also noted that there were no price regulations for faecal sludge emptying services. Through the study, it was found that the private exhausters were charging the customers exorbitantly and there was a need to create a regulatory framework to manage the costs. It was also found that due to the high-water table within the environs of Eldoret and Uasin Gishu County at large, there was a risk of groundwater contamination, especially for the neighbors who solely depended on water from their wells for their daily household use. It was established that the emptying charges were directly proportional to the capacity of the exhauster and the haulage distance to the wastewater treatment plant. In summary, the paper recommends adequate allocation of funds, the involvement of all key stakeholders, the creation of awareness and education in the FSM and the creation of a legal framework or policy governing the management and disposal of FS as we move towards the realization of SGD 6.

Transmission Control Protocol/ Internet Protocol (TCP/IP) is the backbone of Internet transmission. The Transport Layer of the TCP/IP stack, which includes TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) protocols, plays a crucial role in ensuring reliable communication between devices over a network. To come up with measures that make networks more secure, it is important to learn about the vulnerabilities that exist in the transport TCP/IP stack and then have an understanding of the typical attacks carried out in such layer. This paper explores how the TCP Protocol works, the TCP/IP 3 Way Handshake, TCP Header Structure, the typical vulnerabilities and the classical attacks of transport layer TCP/IP, tools, and solutions adopted to prevent and reduce the chances of some of these attacks. The findings indicated that the major TCP/ IP stack transport layer threats include Finger printing, SYN Flood, TCP reassembly and sequencing, IP Spoofing, TCP session hijacking, RST and FIN denial of service attack, Ping of Death, Low Rate/ Shrew Attacks. Their preventive measures and mechanisms are discussed.

Groundwater contamination is a global problem. Although groundwater is considered as safe, high concentrations of heavy metals in groundwater like arsenic (As) can pose potential human health concerns and hazards. Arsenic is a natural chemical element of the earth’s crust and is commonly distributed all over the environment. High concentrations of arsenic (As) in drinking water have been found in several parts of the world. World Health Organization’s provisional guideline value for arsenic in drinking water - 0.01 mg/l (10 μg/l). In Assam, many districts have been reported to be most affected by arsenic contamination of groundwater which is above the permissible level. People in Assam have directly or indirectly consumed the groundwater. This paper emphasizes the overview of the present scenario of intensity of arsenic contamination in groundwater in different districts of Assam. The paper also critically reviews the sources of arsenic contamination and arsenic led human effects.

Fiber-Reinforced Concrete (FRC) marks a significant change in construction technology, providing a way to create more long-lasting, environmentally friendly, and creative building materials. This study explores the many benefits, difficulties, and potential opportunities of FRC, emphasizing its importance in improving building methods. FRC is a composite material that combines various fibers including steel, glass, synthetic, and natural fibers with concrete to increase structural stability by increasing tensile strength, fracture resistance, and impact resilience. Sustainable FRC emphasizes the use of recycled or natural fibers to reduce environmental implications, encourage waste reduction, and conserve resources. Exploring recyclable resources like steel fibers from scrap steel or used tires offers a sustainable option to typical reinforcing materials. This method not only reuses trash but also reduces the carbon footprint linked to new steel production, aiding in achieving sustainable development objectives. The use of natural fibers like as jute, sisal, bamboo, and flax in FRC provides biodegradable, renewable, and low-carbon-footprint alternatives, improving the eco-friendliness of building materials. Although FRC has promise benefits, certain obstacles hinder its broad use. It is crucial to evenly distribute fibers in the concrete mix to provide the appropriate mechanical qualities, requiring improved mixing procedures for consistent dispersion. Moreover, the resilience of natural fibers in the alkaline concrete setting is a notable obstacle, leading to investigations on surface treatments to improve fiber compatibility and lifespan. In the future, combining smart technology with FRC is set to transform the building sector. Advancements like self-healing concrete, conductive fibers, and shape memory alloys provide materials that can repair themselves, monitor structural health in real-time, and enhance mechanical performance. The progress highlights the capability of FRC to enhance sustainability and efficiency in building while incorporating intelligent features to prolong the lifespan and dependability of structures. This study thoroughly examines the environmental advantages, mechanical improvements, problems, and future prospects of FRC. Ongoing research and development are being used to address obstacles in integrating FRC into construction practices, which shows promise in creating more resilient, sustainable, and innovative building solutions. This marks a significant advancement in the search for advanced construction materials.

It is crucial to evenly distribute fibers in the concrete mix to provide the appropriate mechanical qualities, requiring improved mixing procedures for consistent dispersion. Moreover, the resilience of natural fibers in the alkaline concrete setting is a notable obstacle, leading to investigations on surface treatments to improve fiber compatibility and lifespan. In the future, combining smart technology with FRC is set to transform the building sector. Advancements like self-healing concrete, conductive fibers, and shape memory alloys provide materials that can repair themselves, monitor structural health in real-time, and enhance mechanical performance. The progress highlights the capability of FRC to enhance sustainability and efficiency in building while incorporating intelligent features to prolong the lifespan and dependability of structures. This study thoroughly examines the environmental advantages, mechanical improvements, problems, and future prospects of FRC. Ongoing research and development are being used to address obstacles in integrating FRC into construction practices, which shows promise in creating more resilient, sustainable, and innovative building solutions. This marks a significant advancement in the search for advanced construction materials.","PeriodicalId":275182,"journal":{"name":"World Journal of Advanced Engineering Technology and Sciences","volume":"28 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140362263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work addresses the combination of machine learning (ML) and natural language processing (NLP) approaches to optimize the process of courting and RxNorm mapping inside Electronic Health Records (EHRs). Cohorting patients based on comparable traits or diseases is vital for clinical research, but it generally depends on time-consuming manual techniques and is prone to mistakes. Similarly, mapping pharmaceutical names to standardized codes such as RxNorm promotes interoperability and data analysis but may be challenging owing to variances in how drugs are reported. Leveraging ML and NLP may automate and optimize these procedures, leading to more efficient cohort identification and precise medication mapping. We offer a thorough technique for integrating ML and NLP algorithms in EHR systems, including data preparation, feature engineering, model training, and assessment. Through testing and analysis, we show the usefulness of our technique in enhancing cohorting accuracy and RxNorm mapping precision. The findings underline the promise of ML and NLP in revolutionizing EHR data management, leading to improved patient care and simplified research procedures.
这项研究将机器学习（ML）和自然语言处理（NLP）方法结合起来，以优化电子健康记录（EHR）中的求医过程和 RxNorm 映射。根据可比特征或疾病对患者进行分组对临床研究至关重要，但这通常依赖于耗时的人工技术，而且容易出错。同样，将药品名称映射到标准化代码（如 RxNorm）可促进互操作性和数据分析，但由于药品报告方式的差异，这可能具有挑战性。利用 ML 和 NLP 可以自动优化这些程序，从而提高队列识别和精确药物映射的效率。我们提供了在 EHR 系统中集成 ML 和 NLP 算法的全面技术，包括数据准备、特征工程、模型训练和评估。通过测试和分析，我们展示了我们的技术在提高队列准确性和 RxNorm 映射精确度方面的实用性。这些发现强调了 ML 和 NLP 在彻底改变电子病历数据管理方面的前景，从而改善了患者护理并简化了研究程序。
