Sociodemographic Predictors of Knowledge and Practice of Stroke Preventive Strategies among Healthcare Workers in a Tertiary Hospital in Asaba, Delta State, Nigeria
Get PDF Introduction: Stroke occurrence and morbidity are on the increase in Sub-Saharan Africa. Knowledge and practice of stroke prevention with prompt response to symptoms or warning signs are essential elements of a timely diagnosis and disease management. We evaluated Sociodemographic predictors of knowledge and practice of stroke prevention among healthcare workers in Nigeria.
Methods: This was a cross-sectional study designed among 200 Healthcare workers in the Federal Medical Center, Asaba, Nigeria. They were selected by systematic sampling technique. A semi-structured questionnaire was used to collect data on the research variables. Data were analyzed using the IBM SPSS version 25 statistical package.
Results: One hundred and thirteen were female clinical Health workers (54.5%), who were married (63%) and above 30 years (72%) of age. They had good aggregate knowledge (84%) of stroke prevention but with poor practice (61%). There was a significant association between good knowledge of stroke with gender, age above 30 years, having tertiary education, and profession. However, their poor practice of stroke prevention was significant with gender and profession. We found age (95%CI= 0.082-0.865, p=0.028) and profession (95%CI= 0.033-0.350, p=0.0001) as the predictors of good knowledge of stroke prevention, while gender (95%CI=1.771-7.030, p=0.0001) and profession (95%CI=0.167-0.693, p=0.003) as the predictors of poor practice of stroke prevention among Healthcare workers.
Conclusions: These findings suggest the need for older, tertiary-educated clinical Health workers to engage actively in both patients' education and public and government enlightenment campaigns to halt the rising burden of stroke across the globe. 
Development of a Low Cost Poultry Egg Incubation System

The DHT11 sensor is at the core of the temperature and humidity monitoring system, and the system's status is presented on the LCD at regular intervals. The results reveal that the system was able to automatically maintain the temperature within the prescribed range, allowing the eggs to hatch after 21 days. 
The Spatial Constraint Requiring Organogenetic Termination: Supplemental to Haeckel and von Baer for Development and Evolution
Get PDFIn this article, it is pointed out that the requirement for organogenetic termination is the new spatial constraint for animal development and heredity, based on that: (a) organogenesis manifests limitation in time and possession of termination, while infinite cell proliferation known as cancer is lethal; (b) the notable indeterminate growth in some fishes and a few outgrowing skin derivatives reversely demonstrates that termination is required for organogenesis inside the animal. In further, it is supplemented this new spatial constraint to Haeckel and von Baer for development and evolution. While not influencing the temporal and spatial reorganization of morphogenesis during evolution, it places restrictions on alteration of organogenetic mechanisms themselves, as that: (a) addition of new induction mechanism or elimination of termination mechanism would usually cause endless organogenesis, liable to become lethal; (b) addition of new termination mechanism or elimination of induction mechanism in evolution not be affected by this spatial constraint. Finally, it is identified this spatial constraint as partial convergence and partial difference with Haeckel’s recapitulation, and as restriction onto Baer’s tree. It is perspectives to use the method of mathematical probability and statistics to study the spatial constraint of development onto evolution in future. 
Effects of NPSB Fertilizers Rate on the Yield of Common Bean (Phaseolus vulgaris L.) at Tocha District, Southern Ethiopia
Get PDFUse of balanced nutrition means supplying other essential plant nutrients in adequate amount and proportion along with N and P. This implies N and P fertilizers are not the only yield determining nutrients but also S, B, and Cu nutrients are important nutrient for crop production. A trial was conducted in Tocha District to evaluate the rate of blended fertilizers to improve Common bean yield during main cropping season of 2019 and 2020. The experiment consists of seven treatment including (1) control, (2) NPSB: 18.9-37.7-6.95-0.1 (3) NPSB: 28.35-56.55-10.425-0.15 (4) NPSB: 37.8-75.4-13.9-0.2, (5) NPSB: 18.9-37.7-6.95-0.1+0.4kgCu, (6) NPSB: 28.35-56.55-10.425-0.15+0.4kgCu and (7) NPSB: 37.8-75.4-13.9-0.2+0.4kgCu. Soil physic chemical properties of the experimental site had moderately acidic, moderate level of OC and total N, high level of exchangeable K, very high level of CEC, low level of available P and clay loam textural class. In generally, application of blended fertilizer yielded better when compared with control. NPSB with the ratio of 37.8-75.4-13.9-0.2 (200kg NPSB) gave significantly optimum yield (4368.83 kg ha-1) compared to other treatments and also the highest net benefit (18725 ETB/ha) was obtained with acceptable marginal rate of return (MRR) (375.91%) which is more than the minimum acceptable MRR (100%) considered in this experiment. Similarly, NPSB 18.9-37.7-6.95-0.1 gave considerable net benefit with acceptable MRR. Therefore, based on the yield response and economic indicators, 200kg NPSB (37.8-75.4-13.9-0.2) is recommended as the best option and 100kg NPSB (18.9-37.7-6.95-0.1) as an alternative option for common bean producers at Tocha district and areas with the same soil conditions and agro-ecology. 
Assessment of Compressive Strength of Hollow Sandcrete Block Produced in Akure Ondo State
Get PDFThis study aimed at evaluating the properties of sandcrete hollow blocks produced by block industries in Ondo State. The study focused on assessing the compressive strength, water absorption, and dimensional properties of sandcrete blocks obtained from five different producers. The blocks samples were collected from each producer and subjected to compressive strength, water absorption, and dimensional analysis. Also sieve analysis and specific gravity tests were conducted on the sand samples to determine their suitability for block production. The results of these tests indicated that the fine aggregates used were appropriate for making blocks. However, the study found that the compressive strength of the 450 x 150 x 225mm (6") sandcrete blocks was not sufficient. The minimum recorded unit compressive strength was 0.55 N/mm², while the average compressive strength was 0.80 N/mm². These values fell below the standard requirements for load-bearing sandcrete blocks. According to the Nigerian industrial standard, individual blocks should have a minimum compressive strength of 2.5 N/mm², and the average compressive strength of five blocks should not be less than 3.45 N/mm². To enhance the quality of sandcrete blocks manufactured by commercial block industries in the study area, the study recommends standardizing the block manufacturing processes and enforcing strict supervision during production. These measures will ensure that the blocks meet the required compressive strength standards and suitable for load-bearing purposes.

The Emergence of a Novel Anti-Neoplastic Era in Gene Therapy for Cancer: A Review Study
Get PDFCancer is still one of the leading causes of death in the world. The chance of getting the disease is linked to genetic and epigenetic factors. When it comes to treating local cancer, radiotherapy and surgery work the best. Chemotherapy, hormonal, and biological therapies can reach the rest of the organs and tissues through the circulatory system when the tumour has spread. Despite traditional treatments, patients' prognosis has not improved significantly. The toxicity and nonspecific destruction of normal cells required the need to develop targeted and efficient alternative treatments, with gene therapy being one of the most promising techniques.Recent advances in gene therapy have improved the survival rate and life expectancy of patients, as well as treatment possibilities. The most advanced and currently used techniques are CAR-T cell therapy, oncolytic virotherapy and the CRISPR gene editing technique. This work details the advances in efficacy in gene therapy after carrying out several clinical trials, as well as the obstacles and possible future solutions of the main techniques currently used for cancer. Gene therapy is an alternative to antineoplastics that, while not yet a cure for this illness, shows promise and may eventually be included to the standard therapeutic toolkit. Gene therapy is a promising antineoplastic approach that, while not a cure, holds great potential for future medical advancements. 
Research on the Performance and Application of a Low-Carbon Waste-Recycling Cement
Get PDFThis paper mainly introduces the history of the formation and development of an ultra-high performance low-carbon waste-utilizing cement (fast-setting and fast-hardening high-belite sulphoaluminate cement). This cement not only uses a large amount of solid waste (fly ash, blast furnace slag, industrial waste gypsum, alkali slag, etc.) as raw materials, and the waste utilization can reach 40%~95%, but also has a calcination temperature of 150~200℃ and 50 ℃ lower than that of traditional ordinary Portland cement and sulphoaluminate cement, and the carbon emission is equivalent to 30%~60% and 50%~80%. Through the elaboration of its main mineral composition, chemical composition, physical properties and action mechanism, the reasons for its excellent properties such as good whiteness, fast setting and hardening, high late strength, and small dimensional deformation are analyzed. And the application research is focused on the fields of inorganic flooring, airports, road quick repair, prefabricated walls, ultra-light and efficient A-level fire insulation, cement crafts, inorganic artificial stone, and UHPC ultra-high performance concrete. At present, there are many types of low-carbon cement in the world, including Porsol cement, Alinit cement, Celitement cement, Japanese eco-cement, multi-component high-mixture cement, high-belite cement, Anther cement, BCT cement, etc., but most of the products have a slow coagulation and hardening speed, and cannot meet the needs of rapid demolding, turnover, and traffic opening for mortar, concrete, cement products or pavements; at the same time, the production process is complicated and cumbersome, the later strength is low, the deformation is large, and the durability is poor. Therefore, in the actual promotion process in the engineering field, there are great difficulties and many constraints. Among them, Aether cement and BCT cement belong to the belite-sulfoaluminate cement system. Aether cement has 6h early strength performance. Compared with Portland cement (burning temperature1400~1500℃), it can significantly reduce production energy consumption, reduce CO2 emissions by 25%~30% per ton of cement, and the 28-day compressive strength reaches the strength level of standard cement (CEMⅠ52.5R); the size shrinkage of this concrete is less than 50% of that of OPC concrete, but
its raw materials still use limestone, bauxite, gypsum, iron raw materials and marl raw materials, without effective utilization of bulk industrial waste, and CO2 emissions are far from meeting the low-carbon environmental protection requirements. BCT cement can be produced at a lower temperature (1250~1300℃), and its raw materials use industrial waste residues such as limestone, marl, fly ash and industrial by-product gypsum. CO2 emissions are 30% lower than traditional OPC cement clinker, but
there is no early hourly strength, and the strength after 1~2 days is higher than that of ordinary Portland cement. This is far from the goal of using bulk industrial waste as raw materials to produce green, low-carbon, energy-saving and high-performance cement materials, which is currently widely used at home and abroad. At the same time, the above-mentioned low-carbon cement cannot effectively and reasonably control key indicators such as cement whiteness value, early strength before 4 hours, and dimensional change rate, and cannot meet the requirements of high-performance cement. At the same time, the production process is not mature and stable enough, and there is still a long way to go to meet the comprehensive popularization of production industrialization and promotion scale. 
Review Article About Gel Polymers and Their Applications
Get PDFOne of the important applications of hydrogels is agricultural applications, as there is a controlled release of nutrients from the hydrogel into the soil, which are fertilizers loaded on the hydrogel. A large part of the fertilizer added to the soil is lost through leaching, especially in highly porous soils, in chemical processes, heavy rains, etc. A number of different polysaccharides, such as chitosan, pectin and carboxymethyl cellulose have been used to prepare hydrogels as a fertilizer release system for soil revitalization. Many studies have been conducted in this field. For example, Agaba et.al indicated that moisture retention in a particular soil due to the hydrogel is necessary to create a forest. Planted Water affects soil properties such as aeration, temperature, nutrient transfer, water absorption and conversion, which affects plant growth. Dimitri et al investigated the applicability of cellulose-based hydrogels in three different formulations, i.e. crosslinked by carbodiimide, as a carrier for sustained and controlled release of water and as nutrients in arid and desert regions.
