Background of the study: Erectile dysfunction may be responsible for a reasonable amount of male infertility. Erectile dysfunction can lead to male infertility. Male infertility is due to any problem in the male reproductive system including decreased sexual desire, barrenness, premature ejaculation, etc. Method: 20 male Wistar rats and 5 female Wistar rats were used for this study. Male animals were grouped into control, Viagra, high-dose Bay leaves, and low-dose Bay leaves. The extract was administered for 21 days. The animals were acclimatized for one week. Extracts were administered for three weeks. A sexual behavioural study was carried out on the animals in the dark for three days. 24 hours after the last day of the sexual behavioural study, the animals were sacrificed and the testes were harvested and sent for histological studies; semen was collected for semen analysis. Results: Data were expressed as mean ± SEM. The mean difference between the tested groups and the control was tested using a one-way ANOVA. Values were considered statistically significant when P is ≤ 0.05. Mount frequency increased significantly in high-dose groups of both premature plant and bay leaves treated animals. Conclusion: This implies that the plant extract used for the present study increases sexual function (libido and potency).

Wormian bones, otherwise ‘Sutural’ bones, are accessory bones within or near cranial sutures. They are mostly found on lambdoid sutures and can be one or more in each suture. This study is aimed at examining the incidence and frequency of Wormian bones in the dry adult cadaveric skull in Rivers State, Nigeria. Forty-three (43) dry adult skulls were examined for the presence, number, and location of Wormian bone. Thirty-seven (37) of the skulls were from the osteological collections of the Department of Human Anatomy, Faculty of Basic Medical Sciences, College of Health Science, University of Port Harcourt, and six (6) from the osteological collections of the Department of Human Anatomy, Faculty of Basic Medical Sciences, College of Medical Sciences, Rivers State University. 13 (30.23%) of the calvarias had Wormian bones while sutural bones were absent in 30 (69.77%0). 8 (61.53%) calvarias with Wormian bones had sutural bones in the lambdoid suture; with 3 (23.08%) on the left arm and 5 (38.46%) on the right arm of the lambdoid suture. 2 (15.38%) of the calvarias with Wormian bone had sutural bone in the sagittal suture and 3 (23.08%) had Wormian bones in the lambda (Inca bone). The knowledge of incidence of Wormian bone and their calvaric distribution as described in this study is essentially useful to the Anatomist, Radiologist, Pediatrician, and Surgeon in their daily practice, as well as in forensic medicine.

The free fibula flap has emerged as the preferred option for reconstructing defects in the mandible and maxilla. The method of implanting a fibula flap is nearly identical to that used on the original jawbone, but accessing the bone during surgery is the most challenging part. Previous reports discussed the use of dental implants following free flap tissue transfer. This review aims to discuss all the relevant trials discussing dental implants following free flap surgery.

Stock price index futures have long been viewed by experts and scholars as a risk-hedging trading tool that can help investors’ hedge risk and ensure the healthy and stable development of China's financial stock market. The asset underlying of stock price index futures is the stock price index. The CSI 300 stock index futures, a type of stock price index futures, were created on April 16, 2010, and its birth marked the official start of stock index futures trading in China. After the launch of CSI 300 stock index futures, the China Financial Futures Exchange launched (CFFEX) SSE 50 stock price index futures and CSI 500 stock price index futures one after another. The introduction of stock price index futures trading can bring about an impact on the volatility of the stock spot market to a certain extent and play a role in reducing volatility. The speed of transmission of stock index information to market participant decreases after the China Financial Futures Exchange restricts stock index futures trading. Based on the results that the coefficients of DF-DT, the cross term of the two dummy variables added to the GARCH model, have significant values and values less than zero, it can be analyzed that the restrictive measures taken by the China Financial Futures Exchange on stock index futures trading enhance the mitigating restrictive effect of the introduction of stock index futures trading in China on the volatility of the Chinese stock spot market.

The menace of cultism has eaten deep into the Nigerian Institution of higher learning especially in Rivers State and inspite of the jail term for airing members of a cult group caught by the authorities as proscribed in the Nigerian 1999 constitution as amended. This menace is still growing and gaining more grounds in the entire higher institutions on daily basis. Cultism constitutes a major social problem to the peace and harmony that ought to exist within the academic confines of Rivers State. Admittedly the menace have attracted so much tension and concerns of major stakeholders within and outside the educational system and it negative impact affects our universities in terms of disruption of academic calendar, vandalization of school facilities, loss of lives of both innocent and actual cult members within and outside the school environs as well as raping of students. Unfortunately, it has been reported that students who are from disorganized family background that fall prey of joining cult group either in their local environment or when they gain admission into higher institution. This however, is now seen as a very big problem that need immediate solution if the aims and objectives of educating the younger generation are to be actualized. Thus, it further indicates that some factors that motivate the emergence and sustenance of secret cult in the educational system are traceable to the faculty decadence of our immediate society, the parental or student background, the educational environment etc. This study therefore offer some policy recommendations that is needed if we are ready to curtail the activities of cultism in our society and within our educational institutions in Rivers State.

The aim was to study the epidemiological, clinical and therapeutic aspects of paraphimosis at the CSRéf of Markala. Patients and Methods: We conducted a prospective and descriptive study of five patients who had consulted for paraphimosis in the operating theatre of the Markala referral health centre from 1er January 2019 to 31 December 2021, i.e. a two-year period. Our study included all patients who consulted for paraphimosis at the CSRéf of Markala with a usable medical file. The criteria for non-inclusion were: Phimosis without other pathologies of the penis. The records were not usable, as this was a prospective study. Results: The frequency of paraphimosis was 2.1% out of 235 patients hospitalized and operated on at the CSRéf of Markala during the study period. Four of our patients had no particular medical or surgical history, but the oldest of our patients had already undergone a hernia repair and an appendectomy at the time ; the average age of our patients was 15.3 years, with extremes ranging from 3 years to 53 years . However, we note that there is no specific age of onset of paraphimosis The treatment received by all our patients was posthectomy. No major complication was noted in our patients, however we deplore a loss of sight in two of our patients for a long term follow-up in order to identify other unknown aspects in the management of paraphimosis. Conclusion: Paraphimosis is a true urological emergency that occurs in uncircumcised men when the foreskin is trapped behind the glans crown, which can lead to long-term strangulation of the glans and compromise its vascularity hence their immediate management paraphimosis.

Xi Jinping: The Governance of China (Volume III) profoundly answers important theoretical and practical questions about the development of the Communist Party of China and the country under the new historical conditions, and is a representative work of the current Chinese political literature, focusing on the governance concept and governing strategy of the new Central Committee of the Communist Party of China, in which various travel metaphors are used. This research makes a discourse analysis of travel metaphor to help study the translation strategies of the book.

This paper defines and assesses a market timing strategy for the Gulf Cooperation Council (GCC) stock indices, namely the Tadawul All Share Index, FTSE Abu Dhabi General Index, Qatar All Share Index and Qatar Al Rayan Islamic Index. The strategy intends to deliver a consistent reduction in volatility and better risk-adjusted performance. The present empirical study capitalises on the work by Colepand and Copeland (1999) on the US market, re-proposed recently by Bantwa (2020) on the Indian market, which resorts to implied volatility as the trigger to adjust the asset allocation. The strategy hereby proposed is modified considering the higher volatility of the GCC financial markets as well as its preeminent goal – risk-adjusted performance optimisation. Moreover, the implied volatility is unavailable for the GCC stock indices under assessment; therefore, it has been replaced with the forecasted volatility obtained through asymmetric GARCH models (GJR-GARCH), one for each stock index. The active strategy in question is backtested on both the conventional and Islamic stock indices to check whether it overperforms the passive strategy equally well on both types of indices. The empirical findings encourage the adoption of volatility-based market timing models in additional emerging markets and Islamic indices.

Residual soils are in the category of questionable soils which have been experienced in the arid and semi-arid climatic zones of the world. The conditions in these zones favour the development of most unsafe collapsible soils. At their dry natural state, they possess awesome stiffness and high apparent shear strength, however upon flooding, may demonstrate a remarkable reduction in volume, consequently deteriorate in strength and collapse. In this research, the collapse phenomenon of residual soil collected from three locations in Auchi, Northern Edo, Nigeria has been investigated on undisturbed specimens by utilizing single Oedometer test. The results obtained from Oedometer tests were utilized to form the database to develop the Artificial Neural Network model for the prediction of collapse potential induced by flood. The influences of flood, flooding pressure, void ratio, dry density and porosity on soil collapse have been investigated. Six input parameters (i.e. Flooding Pressure, Initial void ratio, Initial water content, Initial dry density, Liquid limit and Initial porosity) are considered to have the most noteworthy influences on the degree of collapse and have been utilized as the model’s inputs while the model output will be the equivalent collapse potential. The proposed network was developed using Microsoft Visual Studio 2010 and the MS.NET Framework 4.0 and source codes were written in C-Sharp (C#). A supervised learning was utilized to train the Back Propagation feed forward multi-layer ANN algorithm with the momentum coefficient and learning rate as its parameters. The prediction performance of the Artificial Neural Network model was assessed by utilizing the primary statistical criterion proposed by Shahin, et al., [1] such as the coefficient of correlation, R2, and the root mean square error, RMSE. The model outcomes demonstrated that it has the aptitude to predict the collapse potential from single Oedometer test in residual soil samples with a good degree of precision with coefficient of correlation, R2 = 0.856 and root mean square error, RMSE = 166.199.

This research work presents a study of the reliability of ground improvement methods in three states of the Niger Delta Area of Nigeria namely: Rivers, Bayelsa and Akwa –Ibom states. Natural soil which is peaty clay in nature was obtained from different locations in the area of study and improved with different percentages of chemicals, cement, ranging from 2% to 10% and geotextile materials after which reliability analysis was carried out on them for CBR and UCS tests. Results show that geotextile materials are not suitable for improving the peaty clay soils in the locations under study due to poor values of reliability while the reliability values obtained for soil improved with cement increases with increase in percentage addition of cement and curing period. Reliability values for soil improved with chemicals shows some variability but increase as curing period increases at percentage addition of chemicals from 2% to 6% for Calcium Oxide, Calcium Chloride, Calcium Hydroxide and Aluminium Hydroxide before a decrease in value. Sodium silicate reliability peaked at 8% while the optimal value of reliability for cement was realised at 10%.

Host genetics of COVID-19 patients is constantly evolving and may play an important role in the management of hospitalized patients and the identification of new biomarkers. In 2022, numerous studies have been published examining genetic factors that may be associated with severe outcomes of COVID-19 disease, as well as different genetic biomarkers have been suggested for early diagnosis of severe SARS-CoV-2 infection. In this literature review, we provide relevant updated analyses, examining studies published in 2022 in the literature that correlate with what was published in previous years and that focused on host genetics in patients with severe or fatal forms of COVID-19, Studies using different genotyping and sequencing techniques for the identification of genetic polymorphisms with promising results on different genes of the Renin angiotensin system, Interferon system, ABO system, Apolipoprotein E, Dipeptidyl petptidase, Leucine Zipper Transcription Factor-Like Protein 1(LZTFL1) and HLA system in diverse populations.

The article is dedicated to the study of the types of migration, the current challenges of emigration and immigration, and the reasons for migration in Armenia, as well as its consequences on the economy and demography. The methods of comparative studies, general scientific analysis, groupings, and generalizations were mainly used in the framework of the research. Emigration has become one of the most drastic challenges in Armenia for almost three decades. There are a lot of reasons for emigration to Armenia: social, economic, psychological, and security. From 2012 to 2019 about 91% of those who emigrated from Armenia were in the 15-59 age group, and more than 65% were in the 20-49 age group. The latter significantly influenced the formation of the age structure of the population. In other words, the negative impact of emigration has begun to be reflected in demographics as well.

This article analyzes the structuring of Construction Law in Middle Eastern countries. It is an excursus that deals specifically with what the Muqawala contract is, its usefulness and also its history, up to an indication of the most important issues and elements of construction contracts in Middle Eastern countries. Specifically, the most important and legally interesting case relating to the resolution of disputes related to incorrect contractual execution was also analysed. In addition, a further analysis was carried out on Arbitration as one of the most common instrument and also the most common form of dispute resolution in contracts involving international Parties and related to the same on a number of increasingly widespread and increasingly used local arbitration bodies including the Dubai International Arbitration Center and DIFC/LCIA Arbitration Centre.

The aim of the research is to examine and analyze the weaknesses of regulations on The Regional Government Public Safety, and how to reconstruct the regulations based on justice value. This research was conducted using socio-juridical research which is a legal research method that functions to see the law in its real sense and examines how the law works in a society that is analytically descriptive using primary and secondary data and using the theory of pancasila justice as a grand theory. The weakness of regional government policy regulations in the field of public security and peace is the regulatory factors where the provisions of RI Law Number 23 of 2014 regulate in a limited manner regarding the requirements to be appointed as civil service police. therefore The Legal Reconstruction of Regional Government Public Safety based on the values of justice is the provision of Article 26 of the Republic of Indonesia Law Number 23 of 2014 and Article 255 of Law of the Republic of Indonesia Number 23 of 2014, that regulate the main task of the Satpol PP to enforce regional regulations and regional regulations, administer public order and peace and carry out community protection. In carrying out these basic tasks, Satpol PP must be equipped with authority. Furthermore, the reconstruction of Article 256 of RI Law Number 23 of 2014, that this article regulates the requirements to be appointed as civil service police. The provisions of this article regulate, although limited, the requirements referred to so that in practice it will be difficult to fulfill them, therefore the regional head can make a policy or discretion. However, this is appropriate when viewed from the hierarchy of laws and regulations because the regional head's policies are not in accordance with the norms stipulated in the provisions of Article 256 of the Republic of Indonesia Law Number 23 of 2014.

The aim of the research is to examine and analyze the weaknesses of regulations regarding corruption crime as a result of the abuse of authority, and how to reconstruct the regulations based on justice value. This research was conducted using socio-juridical research which is a legal research method that functions to see the law in its real sense and examines how the law works in a society that is analytically descriptive using primary and secondary data and using the theory of pancasila justice as a grand theory. The research result shows that the Weakness is in the issue of light sentences for defendants in corruption cases has more or less had an effect on efforts to reduce corruption rates. It is impossible for the government and law enforcement officials to try to reduce the number of corruption cases if, on the other hand, these efforts are countered by light sentences from the Corruption Court and then There is a disparity in decisions in cases of corruption in Article 2 paragraph (1) and Article 3 of the PTPK Law not to mention the Corruption in Indonesia is very widespread and has penetrated all levels of society, a crime that has been deeply-rooted and systemic in the life of the nation and has a very detrimental impact on all aspects of life and Its development continues to increase from time to time. Therefore, a legal Reconstruction is needed in Article 3 of the Corruption Crime Law, by adding a minimum prison sentence of 5 years so that it reads to: "sentenced to life imprisonment or imprisonment for a minimum of 5 (five) years and a maximum of 20 twenty years". and added the revocation of political rights for 5 years against corruptors as an action that should be supported in order to provide a deterrent effect in eradicating corruption amid the low verdict on corruption cases.
