Alternative cheap sources of protein in poultry diets are desired hinged on feed safety, production cost and nutritional quality. The preceding review looks at how baobab seeds have featured as an alternative protein source in poultry diets. This is on the backdrop that the cost of compound feeds continue to be on the rise due to the high expense of conventional protein sources used in manufacturing animal feed. Soya bean has been the predominantly used and most expensive conventional protein source used in the manufacturing of compound feeds. It is suffice to suggest that there is an urgent need to accord adequate consideration to alternative cheap protein sources, and baobab seeds are one such alternatives. Previous studies have shown that baobab seeds have excellent nutritive value, despite containing inconsiderable levels of anti-nutritional factors. Baobab seeds contain some anti-nutritional factors, such as phytate (2%), oxalate (10%), tannins and saponins (3-7%) which reduces digestive efficiency and utilization of dietary nutrients in poultry. However, these anti-nutritional factor levels are generally assumed to be low enough not to cause any adverse effects in avian species. The seeds have a protein value that ranges from 20-36 % CP and an energy level of 4.19-16.75 kJ/kg, which is comparable to sunflower meal (24.4-36.7 CP and 19.1-20.2 kJ/kg) and soybean hulls (10.5-19.2 CP and 17.5-18.7 kJ/kg). It is apparent from previous studies that inclusion of baobab seeds at 5-10% level in poultry diets improves performance of broilers in terms of growth rate. Inclusion of the baobab seeds as partial replacers of soybean meal can be cost effective by inevitability reducing the escalating costs of poultry feed.

In recent years, there are technological growth and the acceleration of industrial development. Although this rapid progress plays a significant role in increasing productivity and economic prosperity, but it also creates new challenges such as health, safety and environment issues. These issues are most evident in developing countries because in order to increase production, regardless of preventive safety principles, standards, working hours, training workers and the use of proper personal protective equipment to workers are addressing excessive pressure on workers. The most people of the world (58%), spend one-third of their life in the workplace. According to the ILO hundreds of thousands of workers are seeing serious injury. Hamalaynyn et al. 98 estimated that about 350,000 fatal occupational accidents and 264 million work-related non-fatal accidents occur. However, economic valuation and pricing of the life is nothing in the last three decades and has been done using new methods. Health, safety and environment management system which is responsible for all matters relating to occupational health, environment and industrial safety of industries. HSE plays a great role in developing of countries through the basics of systematic and various factors related to health, safety and the environment. Applying the principles of HSE management can reduce costs of the employee’s absence, employee's claim and product low quality etc. Implementation of these principles is significant in two aspects: 1. Determining the causes of accidents, diseases and injuries and 2. The impact of these principles on the organization economy. In fact, HSE is an added value for organizations.
近年来，科技进步和工业发展加速。虽然这一迅速进展在提高生产力和经济繁荣方面发挥了重要作用，但也带来了新的挑战，如健康、安全和环境问题。这些问题在发展中国家最为明显，因为为了增加生产，不顾预防性安全原则、标准、工作时间、培训工人和使用适当的个人防护设备都在解决工人承受的过度压力。世界上大多数人(58%)一生中有三分之一的时间在工作场所度过。据国际劳工组织称，成千上万的工人受到严重伤害。Hamalaynyn et al. 98估计，每年大约发生35万起致命职业事故和2.64亿起与工作有关的非致命事故。然而，近三十年来，生命的经济估值和定价都是用新的方法来完成的。健康、安全和环境管理体系，负责所有与行业职业健康、环境和工业安全有关的事宜。HSE通过与健康、安全和环境相关的系统和各种因素的基础，在发展中国家发挥着巨大的作用。运用HSE管理原则，可以降低员工缺勤、员工索赔、产品低质量等成本。这些原则的实施在两个方面具有重要意义:1。1 .确定事故、疾病和伤害的原因;这些原则对组织经济的影响。事实上，HSE对组织来说是一个附加价值。

Process industries have always been exposed to fire, explosion and release of chemical materials. To identify and evaluate risk in process industries including oil and gas, there are various methods in which hazard and operability study (HAZOP) is one of the most common methods. To do this, at first all organizational duties and unit activities are identified. Then, the study technique of operation and risk is used as an effective and sys thematic method to identify risk and operating problems and the relevant effects. The identified activities in risk assessment are applied. The results of evaluation of identified risks showed that 6 cases had hazard higher than 15 and it is not acceptable. In terms of risk intensity, the highest frequency of unacceptable risks (4 cases) is observed in “reformer heating chamber”. The analysis of consequence of hazards showed that for 6 hazardous points, independent layers of protection can reduce risk as 100% to target factor (10 -5 ) and safety integrity level is fulfilled completely.

Nowadays, one of the major issues in wireless sensor networks (WSNs) is data security. Often, data security issue is associated with data aggregation. Using this kind of network in sensitive areas, especially in military environments, without contemplating data security creates main problems. A great number of researches have been conducted in recent years. For example, issues such as coding and use of key and optimum routing based on data security have been taken into consideration. Each method makes use of different parameters that have created strengths and weaknesses. The present research is intended to consider the new ideas presented in this field. Then, to contribute to strengths and weaknesses existing in these methods, we present new ideas. The routine is to study new methods in a valid research. Issues such as data integration, individual or multiple data transfer, the impact of genetic algorithms on data security, encoding and cryptography, secure data aggregation based on fuzzy logic, etc have been discussed thoroughly.

Using descriptive method of data gathering: qualitative analysis of data from secondary source, the study x-rays the performance of the parliament at the federal and state levels between 1999 and 2016 to see whether it has enhanced good governance in the country. The study implicates corruption as the major reason for the ineffectiveness of this arm of government. It is therefore imperative to alter the nation’s leadership recruitment process such that patriotically-minded and unblemished Nigerians will be attracted into politics and contest for parliamentary positions.

Nigeria remains a creeping giant today due to the alien and expensive political arrangement that creates the opportunity for elite conspiracy which impoverishes the masses and underdevelops the country. Using descriptive method of data gathering, the study reveals that western democracy cannot work in Nigeria irrespective of how educated the population is because of the deep seated corruption, primordial sentiment, ethnic and religious prejudice as well as lawlessness. A revolutionary leadership is needed to fashion out a workable and effective political system such as Africasian democracy that would suit the Nigerian society and respond to the infrastructural needs of the masses.

Nigerians are increasingly losing hope and confidence in the nation’s judicial system because of the unethical conduct of some judicial rascals. Some judgements have brought embarrassment to the nation. Verdicts are no longer based on facts of law. Through indirect observation: reading newspapers, listening to news on TV, It is established that a large number of judgements delivered were based on rule of men, and status differentials instead of rule of law. It is recommended that the judiciary be urgently overhauled with a view to flushing out the bad eggs or the judicial rascals.

Nigerians are increasingly losing hope and confidence in the nation’s police force because of the unethical conduct of some of its operatives. Some of the actions of the Nigerian Police Force have brought embarrassment to the nation. Cases of bribery or extortion and extra-judicial murder are on the increase. The paper looks at the poor outing of the police and how it impedes the rule of law. Through direct and indirect observations, it is established that the rule of law has been disastrously negated by the unprofessional attitude of the largely ineffectual police force. It is recommended that the minimum entry qualification into the Force should be HND.

In this paper, we have found out the impact of foreign direct investment on the development of Pakistan and Azerbaijan. We have utilized the secondary data for accord results. Our results showed that ratio of foreign direct investment is high in few countries and also low due to terrorism. In 1992, the inflow of foreign direct investment is high at the same year inflows in Azerbaijan were at the poor rate. In the year 2009, the inflows in Pakistan were 245.45 US dollars while in Azerbaijan the inflows were nothing. Our paper is trying to explore that most revenue area in business are education and information technology. On the other side, our paper is also trying to show that foreign direct investment is backbone of the economy. Therefore, we suggested that Pakistan and Azerbaijan should remove such factors which have an impact on the foreign direct investment.

Among the work-related risk factors in different industries exposure to chemicals can be mentioned that can have irreparable danger to staff. Therefore, to reduce the risk of exposure to chemicals in the workplace, risk assessment takes place. Thus, the aim of the present study is to study the semi-quantitative risk of chemicals. This study was conducted using semi-quantitative risk assessment method provided by the Singapore Ministry of Labor Health and Safety Unit in Olefin unit of one of the petrochemical industries located in Special Zone Asalooyeh in 2015. Seven chemical substances are identified in this unit that only one of them (14.2 percent) has a high risk level. The results showed that in this unit Sodium hydroxide (caustic) with quantitative risk level of 4.3has the highest risk factor. For this reason, control measures should be used to reduce the risk of exposure to sodium hydroxide.
