PROBABILISTIC SAFETY OF ESTUARY VESSELS BASED ON NONLINEAR ROLLING IN WIND AND WAVES

The author was previously involved in the development of the risk-based stability analysis which is now further extended, and used for the safety assessment of estuary container vessels subjected to stochastic action of beam wind and irregular waves. The study was motivated by the new set of safety regulations for estuary vessels issued by Belgian authorities in cooperation with Lloyd’s Register. These regulations introduce very innovative probabilistic ideas to ship stability regulations, and therefore present a significant step forward compared to the classical approach. Still, they do not account properly some important influences, such as wind gusts and motion nonlinearities, so considerably simplify the problem. The present investigation models the vessel motion much more realistically, analyzes the influence of beam wind and beam waves on the probability of a stability failure, and argues whether simplifications proposed by the regulations were justified. It is believed that presented method is not limited to the safety of estuary vessels only, but also gives important guidelines for a more general investigation of ship safety in wind and waves.

The role of the Palestinian police in protecting victims of crimes: دور الشرطة الفلسطينية في حماية حقوق ضحايا الجريمة

This paper aimed to identify the role of the Palestinian police in protecting the rights of victims by informing the victims of their rights, and determining the victim's right to protection by the judicial police. The researchers used the descriptive and analytical approach based on legal texts related to the protection of the rights of crime victims. This research paper concluded with a set of results and the important results are protection the human rights is the only way to make the human responsive about his community, and the balance between the individual rights and freedoms, the country right, community interest and it’s security and stability is vital necessity. The evidence of Palestinian police Confirmed the rights of victims in protection, and their right of recognizing their roles and the procedures that must be followed in their issues. At the end the two researchers recommended that police officers, especially judicial officers and the General Investigation Department, should receive adequate training to make them aware of how to deal with victims of crime. And how to define the victim's needs, know the principles of providing appropriate and immediate aid, establish rules for listening to the victim's complaint, deal with it and help her, and the need to notify the victim of interest in his case, and to inform him that his presence at the police headquarters will bring him justice and fairness.

Women’s Constitutional Rights

This chapter explains how legal syncretism influences and manifests itself in the design and practice of constitutional rights—with a particular focus on women’s rights—in the constitutional systems of Nigeria, South Africa, and Ethiopia. The chapter demonstrates how the interaction between the liberal and indigenous conceptions of rights in a constitutional space produces unique regimes of women’s rights in these countries. The chapter first presents a brief theory of women’s rights as a standard of comparison and evaluation; this is done through a more general investigation of women’s rights in international law. This is then followed by a more focused discussion of women’s constitutional rights in Nigeria, South Africa, and Ethiopia. Such discussion explores the substantive content and the way in which women’s rights are constitutionalized, as well as their practical and judicial applications. The syncretic nature of women’s rights in these countries sheds some light on the importance of looking beyond the universalism versus cultural relativism debate when trying to enforce human rights in Africa.

The payload-range performance of a multirole tanker transporter aircraft accounting for towline (on-station refuelling) and trail (strategic deployment) missions

This article has arisen from a general investigation into the payload-range envelope of a multirole-tanker transport aircraft and how this envelope is modified as a result of the tanker’s refuelling activities. To this end, the Breguet range equation is used in conjunction with a simple fuel budget to model different scenarios in which the tanker aircraft can perform towline or trail missions. For the common radius of action case, a closed-form solution is obtained for the payload-range variation; for instances where the outbound journey and the return journey are of unequal lengths, the governing equation is found to require a numerical solution. The act of dispensing a significant quantity of fuel whilst some distance into a flight can have a dramatic impact on the tanker’s overall range and payload capability. An assessment of this payload-range modification needs to be made prior to commencing the flight to ensure the mission can safely be accomplished, which provides the motivation for the current work. Three case studies are presented to demonstrate the efficacy of the method, and comparisons with published data show strong agreement. This model will be of use to planners wishing to investigate typical ‘ what if?’ scenarios on the overall mission.

Papular mucinosis (papular lichen myxedematosus): Clinical and histopathological evaluation

Background: Papular mucinosis is a variety of mucinosis characterized by excessive production of mucin by fibroblasts and deposition in the dermis. It manifests itself with fleshy papules or plaques in different sites of the body and taking different clinical morphological cutaneous features. Objective: The objective is to report and evaluate the different clinical and histopathological features of the disease in Iraqi patients. Patients and Methods: This is a case series and a clinical descriptive study in which ten patients with papular mucinosis were reported during the period from 2012 through 2019. The age ranged from 4 to 56 years, with seven females and three males. Clinical evaluation regarding histories of the disease and examination was carried out. General investigation was done and skin biopsy for histopathological assessment was conducted. Results: Nine patients were adults, with their age ranging from 20 to 56 years, a mean of around 35 years, and only one 4-year-old child. It is a disease with a female predominance, as observed in 7 (70%) females. The common sites of involvement were the face but the rash may extend to affect the neck and upper arms. The rash appeared in the form of skin-colored or red fleshy papules and plaques or in diffuse erythematous orange peel-like forms. The rash was asymptomatic in most patients. The pathology of the disease clarified the diffuse deposition of mucin in the dermis, as was demonstrated with H&E staining. Conclusion: Papular mucinosis is a rare disease characterized by mucin deposition in the skin affecting mostly adult females. The face is commonly involved together with other areas such as the neck and upper arms, but the trunk and lower limbs are spared. It manifests itself with different clinical morphological cutaneous features. Papular granuloma annulare must be considered as an important differential diagnosis in all cases of papular mucinosis.

The role of SMES’ market orientation in developing countries: a general investigation in four countries

SMEs are limited in their business development. This study is built on previous research conducted in four developing countries (Nigeria, South Africa, Turkey and India). It is difficult to access a bank to get a loan, they have no understanding of how to produce quality products or services, and they have no awareness to get used to learning; these are the problems faced by SMEs.The goal of this study is to find out market-oriented strategies to achieve performance in SMEs that are often ignored because they are too expensive. Review papers were used in order to get the stated aim. This study found out that market orientation is not carried out by most SMEs. There are high investment costs for this. Market orientation cannot always guarantee the success of their business. Problem solving was chosen as a strategy in an effort to make market orientation roles more visible, like easy access to finance, awareness of the quality of products and services they produce, and the habit of continuing to learn. The government, along with SME owners and other interested parties, makes some appropriate formulations to strengthen the position of SMEs as a driving force of the economy. It was concluded that SMEs must obtain special policies regarding the ease of financing from banks, availability of training organized by the government to raise knowledge of quality and awareness to always learn, and enabling SMEs to compete with large companies.

A General Investigation on the Differential Leakage Factor for Symmetrical and Asymmetrical Multiphase Winding Design

This work provides an investigation based on a fast estimation of the degree of unbalance (D.U.%) and the differential leakage factor (σ0) of multiphase electrical machine windings. This analysis is carried out by exploring almost 5000 combinations in terms of number of slots, pole pairs, phases and layers. The variability of the leakage factor is examined for each condition, defining an optimal region for its minimization. As a result, an extended mapping is carried out for both the degree of unbalance and the leakage factor, providing a useful tool during the early design stage of winding configurations for multiphase electric machines, even with slight asymmetries. The results obtained from this investigation are validated through finite element analysis and demonstrate that the differential leakage factor can be significantly reduced by adopting winding configurations with slight asymmetries, which also represent a valuable alternative in the electrical machine design.
