The research paper is mainly concerned with characterizing green HRM practices and determining the nature and type of relationship between green HRM practices and how to improve OP in the oil sector in Bahrain. A descriptive researchdesign and survey were used in this research. It Should be noted that a structured questionnaire was designed as well as distributed to a random sample for the purpose of data collection to achieve the study's objective. The targeted population inthis study is mainly comprised of employees from all levels of management. The sample size included employees across all levels (high, middle, and executive management) working in Bahrain's private drilling company. The unit of analysis included a random sample that was estimated to be (175) employees, male and female, who had an equal chance of being chosen and will be treated anonymously. Data will be primarily collected using structured questionnaires. The online questionnaire is designed primarily depending on the Likert Scale (rating scale of 5 points). The results of the research showed that Green HRM Practices (GRS, GTD, GPA, GCR, and GEE) have a positive relationship with OP. This research addressed a proposed model for future empirical study in terms of GHRM practices.

Pavement degradation results due to both ecological and structural reasons. It is never easy to sustain the road to the exact specifications that were kept at the time of opening. With the passage of time, the pavement structure deteriorates. Hence, pavement distresses like different kinds of cracks, holes, and undulations start appearing. Maintenance is an essential practice in providing for the prolonged performance and the aesthetic manifestation of an asphalt pavement. Pavement maintenance aims to rectify deficiencies triggered by distresses and protect the pavement from further damage. The present research seeks to evaluate the distresses produced in flexible pavement. The northern bypass road located in Peshawar, Pakistan, was under consideration as a case study. A methodology was proposed to investigate the pavement condition, consisting of a manual survey performed as per the ASTM D 6433 standard. The pavement was split into different sections. Each section was further divided into sample groups. The kind and severeness of sample distresses were evaluated by visual scrutiny of the pavement sample groups, and the amount of each distress was quantified. This process required a crew of two engineers. It was inferred that identifying defects and knowing their roots could help improve rating pavement conditions and select cost-effective repairing methods. The periodic inspection was found to be necessary for providing current and valuable evaluation data. It was recommended that ratings should be updated every year.
路面退化既有生态原因，也有结构原因。要把这条路维持到开放时的精确规格，从来都不是一件容易的事。随着时间的推移，路面结构逐渐老化。因此，路面出现了各种裂缝、洞和起伏。维护保养是保证沥青路面长期使用和美观的必要措施。路面维修的目的是纠正因事故引起的缺陷，并保护路面免受进一步的损坏。本研究旨在评估柔性路面产生的痛苦。位于巴基斯坦白沙瓦的北部绕行公路正在考虑作为一个案例研究。提出了一种调查路面状况的方法，包括按照ASTM D 6433标准进行的人工调查。人行道被分成了不同的部分。每个部分进一步分为样本组。通过对路面样本组的视觉审查来评估样本窘迫的种类和严重程度，并对每种窘迫的数量进行量化。这个过程需要两名工程师。由此推断，识别缺陷并了解其根源可以帮助改善等级路面状况并选择具有成本效益的修复方法。认为定期检查对于提供最新和有价值的评价数据是必要的。建议每年更新评级。

Over time, a variety of composites are formed at the research and industrial level where not all the time the results are in favour. Various reasons exist in the formation of a composite in which the role of revolutions per minute (RPM) is one of them. Therefore, the aim of this research is to explore the impact of RPM in making the composite. For this purpose, multi-layer graphene (MLG) and polydimethylsiloxane (PDMS) was taken to formed two composites, in which one was prepared by adding the ethanol in MLG and later mixed with PDMS, and the other was prepared by direct mixing of MLG with PDMS. The physical and experimental inspection was made where the results reveal that a unique dispersion was achieved at low RPM in the first sample. However, the FTIR analysis revealed a less existence of MLG in both the formed composites. Although the low RPM speed was kept at 100, still less MLG sign was visible in the sample. Therefore, a further investigation is required to observe the loss phenomena of MLG within the composites due to the RPM speed.

Fallacious waste management is an enormous enemy towards a healthy environment. Currently, the world's waste is categorized into municipal solid waste, industrial waste, agricultural waste, and hazardous waste. In earlier days instead of using different methodologies for waste segregation and management, people used similar methods for assorted kinds of waste produced in varying categories. But in recent years there has been a huge leap in techniques that involve segregation of waste and then proper disposal process. The two major technologies that have been developed for eradicating the complications in the field of waste management are IoT (Internet of Things) and deep learning. Apart from segregation and managing the garbage, the collection of garbage is also an important task. When the garbage isn't collected at regular intervals of time, it affects the health of citizens residing in that surrounding area. Both the technologies have done great work in eradicating this communication gap and made sure that proper segregation of waste takes place leaving no stone unturned. This survey paper discusses various strategies of waste segregation and management.

Corporate sustainability concept emerged globally over the last two decades with the increased awareness of sustainable development by organizations. Following that, many empirical studies have tackled the industrial sector, which constitutes a vital part of the economy in most countries, and is one of the leading sectors in adopting the three dimensions of corporate sustainability (social, environmental, and economic). This quantitative study aims at developing and testing a conceptual model for assessing the impact of corporate sustainability adoption on organizational performance of this vital sector. The proposed model was empirically tested through a sample of 140 senior employees of eight industrial companies in three MENA countries (Bahrain, Saudi Arabia and Egypt). Non-parametric tests were employed to test research hypotheses. Results revealed a positive relationship between organizational performance, and the adoption of corporate sustainability measures for both environmental and social dimensions.

Urban and peri-urban development is one of the most underestimated causes of soil destruction. Therefore, the general aim of this study was to evaluate urban sprawl in the great EL Jadida. The methodology adopted is based on a diachronic study of multispectral satellite images (TM, ETM, and OLI) using two classification methods (maximum likelihood and spectral indices). This methodology allowed the reconstruction of trajectories of changes in land occupation and land use, highlighting the artificialisation of the territory and the privileged extension zones of urban and peri-urban sprawl between 1985 and 2019. This study reveals that the artificialization of the great El Jadida from 1986 to 2019 confirms solid urban growth. The area of land invaded by urbanization was approximately 5899 ha. Thus, the evolution of urban space from 1985 to 2019 revealed an average progression of approximately 174 ha per year. There is also a substantial regression of agricultural land around 6976 ha.

The aim of this study is to examine the association between the firm's ownership structure characteristics and the dividend payouts of the publicly listed non-financial companies in Gulf Cooperation Council (GCC) countries. The study applied a multivariate regression model and found a significant positive association between institutional ownership and the firm's dividend payouts. However, the study found no significant relationship between affiliate ownership and block ownership with the firm's dividend payout. The study findings can provide a valuable insight to the shareholders in GCC countries and aid in understating the impact of different ownership structures on the firm's dividend payout policies through the prospective of the agency theory. Also, the study can support the shareholders in reducing the agency problem by establishing a more effective ownership structure.

Pumice stone, known as the lightweight aggregate, is a mixture of lava and water used to replace coarse aggregate in construction. Nowadays, lightweight concrete has many applications in the concrete and construction industry. This study aims to overcome the project's cost and re-use the waste material dumped by the textile industry known as a pumice stone. Besides, an attempt has been made to compare the conventional concrete and lightweight aggregate concrete (LWAC) using a mix ratio of 1:1.5:3 and determine the strength parameters of LWAC. Lightweight concrete is made by partial replacement of coarse aggregate with different proportions of pumice stone ranging from 10%, 20%, 30%, 50%, 75% and 100%. Furthermore, several tests have been conducted to investigate mechanical properties such as compressive strength and tensile strength of lightweight concrete and compare them with conventional concrete. A total of 42 cylinders were cast and prepared, in which 21 cylinders were for compressive strength and 21 for tensile strength. Each set of 3 cylinders was cast for 10%, 20%, 30%, 50%, 75%, and 100%, making 21 cylinders for compressive strength and separate 21 cylinders for tensile strength with the same proportions. The experimental results show that the strength gradually decreases as the percentage of pumice stone increases. Therefore, up to 30% of lightweight aggregate as a partial replacement gives the desired compressive strength. Besides, the split tensile strength decrease when the percentage of pumice stone increases and gives the desired strength up to 30% replacement. Therefore, it is concluded that 30% replaced concrete can be effectively used for structural purposes, whereas 50%, 75%, and 100% can only be suitable for the non-structural members.

The private sector in Bahrain is booming and playing a vital role in executing women empowerment in all aspects. Therefore, this study has been conducted to measure the women empowerment practices in Bahrain's private sector, which is rapidly growing and developing. Furthermore, the authors have tackled this topic by designing a model consisted of six variables: company clear vision, administrative practices, Human resources strategies, career development programs, performance appraisal practices, and government regulations. Therefore, the authors selected four industries in the private sector (Education, Health, Financial and Telecommunication), which were surveyed using a quantitative research approach to indicate and assure the variability of participants. An online self-administrated survey reached a sample size of 301 Bahraini female staff identified by four industries in the private sector in Bahrain. The results of the study indicated that the model has a relationship with empowerment practices. Based on simple regression analysis, the highest positive impact on women empowerment was found from administrative practices/laws, followed by human resources strategies, career and development, performance appraisal practices, clear vision and mission about women, and finally, government encouraging practices. However, multiple regression analysis showed that administrative practices/laws, followed by career and development, and finally, human resources strategies, only have a statistically significant effect on women empowerment.
