The growing of X-ray imaging around the world has implication towards radiation protection of medical field. Higher usage in radiation commonly have been seen as a simple workload issue without future challenges. Unfortunately, due to improvement in technology and techniques, it caused the amount of X-ray procedures increase which requiring medical professionals in order to ensure patient who exposed to radiation has maintain their close physical contact. As many processes are complex, risk of severe occupational exposure become higher, thus necessary steps should be considered. It is important to ensure the lower effects of exposure are achievable. If the dosage limit for the lens of the eye is lowered in the near future, additional attention to eye protection may be required. There are many essential elements needed in ensuring medical field especially for X-ray imaging to be more proper and reasonably secured for example education and training in radiation protection.

Desalination is emerging as one of the most promising solutions to extraction and increasing global demand for drinking water. A water purification process called reverse osmosis (RO), in which dissolved solids are separated from solutions by partially permeable membranes. Advances in membrane technology have resulted in the removal of up to 99% of salts in seawater. However, the process and system of seawater treatment RO are associated with many problems, such as scaling and fouling of the membranes, corrosion of the pumps, valves and piping system due to the highly concentrated salt solution and high chemical consumption. Nowadays, these problems have become very critical as they severely affect the desalination process and also massively deteriorate the performance and lifetime of the system components and materials. To ensure that the desalination process is always the best option for a low-maintenance, highly efficient and cost-effective system and process, a comprehensive study of these problems is essential. Therefore, this article addresses the characteristics of metallic materials and corrosion problems in the reverse osmosis process of seawater desalination, as well as the best solutions to focus on and evaluate for an optimal seawater desalination process, and the selection of the category of duplex stainless steels suitable for seawater desalination plants to reduce maintenance, avoid plant shutdown and ensure plant safety.

Abstract
In Malaysia, the current methodology for decontaminating ambulances is by manually cleaning surfaces with Environmental Protection Agency (EPA) approved disinfecting solutions as contrast to previous practice using water and soap. The solutions used are registered with National Pharmaceutical Regulatory Agency (NPRA) Ministry of Health Malaysia (NPRA) to ensure adherence to international standard of practice. The manual decontamination practices are effective if strictly conducted following guidelines. However, the proper cleaning and decontamination of an ambulance is an important task that frequently overlooked. It creates a risk to healthcare providers and their patients for subsequent ambulance trip. To ensure the patient compartment is absent from multitudes of infectious pathogen especially Covid-19, is not only an escalating challenge for healthcare providers as it is an unseen, but also poses a real threat to them and their patient. The healthcare managers should consider technologies that can provide a safer, effective and more efficient cleaning and decontamination of an ambulances. We proposed to adapt a new approach of decontamination by using a vapour based disinfection method coupled with germicidal enhancement using ultra violet. It utilizes an EPA-approved hospital disinfectant to decontaminate surfaces in the patient care compartment after every patient transport. A nozzle, placed inside the patient care compartment, disperses a mist of disinfectant solution that designed to meet standard requirement. The enhancement of germicidal effect using an ultra violet ray will disinfect and ensure a free patient compartment from an infectious organism. This decontamination system directly integrated into a new or existing ambulance. It is convenient, timesaving, hands-off solution for decontaminating of an ambulance and importantly creates a safer practice.

Abstract
Public facilities are to be located optimally in the interest of society. In Nigeria, public facilities' locations are largely influenced by administrative constraints and politics, rather than efficiency and equity. This practice limits access, most especially, in rural communities where the population is dispersed. Studies on efficiency and equity in access to public health facilities focused on urban centres. The aim of this study, therefore, is to advance the understanding of the application of the spatial decision support system (SDSS) to evaluate efficiency and equity in access to public facilities in rural regions. The study used Ogun State, Nigeria as a case. The data used include the population and coordinates of the location of the settlements, coordinates of the location of health facilities and the transport networks. This study showed that 38.5% of settlements do not have access to primary care and the application of the p-median model showed that the efficiency of the existing location of health facilities can be improved by 40.6%. Application of the maximal covering location model showed that the existing maximum travel distance of 26.3km can be reduced. It can be reduced for the sake of equity to 9.9 km. This study demonstrated ways to develop evaluative tools for analyzing the distribution of public facilities in Nigeria. It is suggested that planners in rural regions of other developing countries can adopt these techniques and tools to make their location decisions more logical.

This study investigated the feeding value of Aspergillus tubingensis xylanase-treated rice husk in broiler chickens. The objectives of the study are (I) to investigate the effect of xylanase treatment on the utilization of rice husk in broiler chickens and (II) to determine the optimum level of xylanase-treated rice husk that can be tolerated by broiler chickens. Xylanases are hydrolytic enzymes that degrade xylan and hemicelluloses located in plant cell walls, into xylose which is a reducing sugar and enhancing nutrient digestibility in animal feeds. The production of extracellular xylanase by a locally isolated Aspergillus tubingensis was conducted using solid-state fermentation. The selected isolate was identified by cultural techniques and verified by molecular identification. Conventional feed ingredients such as maize is the primary cereal as source of energy in broiler diet. High cost, availability and competition existing among man, industry and livestock has necessitated the need to find cheap and available alternative feedstuffs for maize in poultry diet. Rice husk is one of the alternative feedstuffs but characterized by high fibre content and Non-Starch Polysaccharide (NSP) (Dalibord, 2006). Thus, addition of the xylanase enzyme breaks the NSPs resulting in plant cell wall destruction after releasing the trapped nutrients such as starches and proteins within fibre-rich cell walls (Gade et al., 2017). Crude xylanase produced was used for enzymatic degradation of rice husk to improve its nutritional value. The rice husk was initially subjected to physical pre-treatment by soaking in water for 24 hours or ground to increase the surface area. Pre-treated rice husk was treated by spraying xylanase onto the rice husk at 100g/ 0.2mL representing the concentration level that recorded the best degradation of fibre content in the treated rice husk. Xylanase-treated rice husk (XTRH) was used with other ingredients in formulating a broiler chicken diet at different inclusion levels. The experiment was a complete randomized design with five experimental diets containing xylanase-treated rice husk at different inclusion levels 0, 5, 10, 15 and 20 kg/100kg. The control diet contained no xylanase-treated rice husk (XTRH). There were five (5) treatments each with three (3) replicate cages of eight (8) broiler chicks totalling 120 birds for the feeding trial. One hundred and twenty (120) day-old chicks with an average weight of 54.85g were randomly allotted to five dietary treatments formulated with 0 (control), 5%, 10%, 15% and 20% (XTRH), and fed for eight weeks. There were three replicates of eight (8) birds per treatment. Results showed that the performance of Broiler chickens such as feed intake, and weight gain feed fed diet containing a 20% inclusion level of xylanase-treated rice husk was significantly higher (p<0.05) compared to other treatment diets. This showed an improvement in the utilization of a high-fibre diet, nutrient digestibility, g

The gripper is required because it is the portion of the robot that makes direct contact with the object being grasped. It should weigh as little as possible without compromising functionality or its performance. This study aims to reconsider the construction of a lightweight robotic gripper by modifying the gripper's materials and topology. Using the finite element (FE) method, several types of gripper materials were evaluated for static stress. On the basis of the results of the FE analysis, the optimal material candidate was chosen using the weighted objective method. Using the Fusion 360 software, the topology of the selected material was then optimized in an effort to achieve the 40% weight reduction’s objective. In addition, the suggested optimized geometry is then fine-tuned so that it can be manufactured as efficiently as possible. The final step in the validation of the robotic gripper's design was stress static analysis. The revised gripper design has a mass of 0.08 kg, a reduction of 94% from the original mass, and a safety factor of 3.67%, which satisfies the desired level of performance for the robotic gripper. Utilizing different materials and optimizing the gripper's topology can significantly reduce the overall mass of a robotic gripper.

Recently, new indices have been developed for better prediction of health status. This study aimed to compare the new indices of anthropometric measurements of women of reproductive age (WRA) in urban and rural settings in Kano state. A cross sectional descriptive community-based study was performed in 240 WRA (15-49 years) in 4 randomly selected Local Government Areas (LGAs) in urban and rural settings each. A structured questionnaire was used to collect information on socio-demographic characteristics. Anthropometric indices which include body adiposity index (BAI), abdominal volume index (AVI), Conicity index (CI), a body shaped index (ABSI), a body shaped index z score (ABSI z score), hip index (HI), body roundness index (BRI) and ponderal index (PI) were measured. Socio-demographic result shows that age, occupation and monthly income were found to be significantly associated between the urban and rural participants whereas education, number of children and pregnancy status were not significantly associated. Urban and rural participants had a significant association in BAI (p=0.006), AVI (p=0.010), HI (p=0.030), BRI (p=0.003) and PI (p=0.002). There were no significant association in CI (p=0.219), ABSI (p=0.498) and ABSI z score (p=0.680). Further investigation of these indices and their association with nutritional status and different diseases could assist in efforts to prevent unfavorable health conditions among women of reproductive health.

Medical data need to be managed appropriately as singly it is meaningless. Data aggregation is important as it may transform a plain data into a meaningful facts known as information. It is crucial to gather an authentic and accurate data analysis for making a critical decision in patient care. We intend to describe on how vital sign-based scenario data can become a meaningful information to assist healthcare in improving patient management. It was hoping that, through vital sign-based scenario medical data aggregation it will highlight or create a new information and knowledge towards diagnoses. This will help in quality patient care management as it may formulate an accurate diagnosis thus provides a support for an optimal medical treatment. In medicine, failure to analysed a correct information will lead to significant morbidity and mortality.

In water processing industry, pressurised pipeline problems bring dangerous consequences, causing flooding, traffic accidents or death, financial and material losses and the disruption of the water supply. There are some problems in water pressurised pipelines system occur gradually, and some problems occur in very sudden without any warning with massive impacts and harms. Most of the sudden events that affect water system and municipal operation and maintenance centres are the phenomenon of sudden explosions and cracks in water pipes which lead to disaster. The phenomenon of water hammer is as a result of imperfect design or poor operation methods. The transition in the pressurised pipeline from one steady state to another steady state such as from a constant velocity to another velocity without a protection system make huge in pressure change. Any change in velocity leads to a pressure changes in very short time will cause to disaster strikes for the system stabilization. Professional design of liquid pipelines and proper selection of materials prevents the phenomenon of water hammer. Therefore, in this paper, the important issues on water hammer, protection systems and professional planning with special software programmes such as Allievi software was addressed.
