Insights on Illegal, Unreported and Unregulated (IUU) Fishing Activities by Egyptian Vessels in Neighbouring Countries
Illegal, unreported and unregulated (IUU) fishing is recognised as one of the largest threats to the sustainability of the world’s fisheries. The fight against IUU fishing activities has recently become a high priority in the international fisheries management agenda. While a number of academic contributions have sought to improve the understanding of the problem, data are still limited, especially in developing countries. In the absence of any information in this regard in Egypt, this contribution is the first attempt to report the available information about cases of Egyptian fishing vessels detained for fishing illegally in neighbouring countries, including the Mediterranean and Red Seas. The highest number of cases was observed in 2015 (7 cases) followed by 2010, 2013, 2016 and 2020 (each with 5 cases). The highest number of detained vessels by far was observed in 2020 (44 vessels) followed by 2015 (19 vessels). Tunisia was the country with the highest number of cases (17 cases) followed by Libya (10 cases), while Somalia detained the highest number of vessels (42 vessels) followed by Libya (22 vessels). The results shed light on the problems that led to this situation, starting with depleted fisheries, a poor monitoring system and a difficult economic situation in the fishing sector
Evaluation of E Layer Dominated Ionosphere Events Using COSMIC/FORMOSAT-3 and CHAMP Ionospheric Radio Occultation Data
At certain geographic locations, especially in the polar regions, the ionization of the ionospheric E layer can dominate over that of the F2 layer. The associated electron density profiles show their ionization maximum at E layer heights between 80 and 150 km above the Earth’s surface. This phenomenon is called the “E layer dominated ionosphere” (ELDI). In this paper we systematically investigate the characteristics of ELDI occurrences at high latitudes, focusing on their spatial and temporal variations. In our study, we use ionospheric GPS radio occultation data obtained from the COSMIC/FORMOSAT-3 (Constellation Observing System for Meteorology, Ionosphere, and Climate/Formosa Satellite Mission 3) and CHAMP (Challenging Minisatellite Payload) satellite missions. The entire dataset comprises the long period from 2001 to 2018, covering the previous and present solar cycles. This allows us to study the variation of the ELDI in different ways. In addition to the geospatial distribution, we also examine the temporal variation of ELDI events, focusing on the diurnal, the seasonal, and the solar cycle dependent variation. Furthermore, we investigate the spatiotemporal dependency of the ELDI on geomagnetic storms
La pertinence informationnelle des données comptables : Une exploration théorique et méthodologique
Cet article expose une revue de littérature relative à la qualité de l’information comptable à travers la pertinence informationnelle, afin de cerner les contours et les interprétations du cette approche. Nous nous focalisons sur la méthodologie des études d’associations, notamment le modèle de prix et le modèle de rentabilité. L’objectif ultime étant d’estimer la corrélation entre les données boursières, les données comptables (en particulier le résultat), les capitaux propres et les cash-flows.
Afin d’étudier le lien entre les valeurs comptables et la valeur de l'entreprise, il faut un modèle de régression vérifiable empiriquement, fondé sur un modèle d'évaluation théorique. Les modèles d’association de prix et de rendement dérivés du modèle d’Ohlson sont les modèles de régression les plus répandus dans les travaux récents. Nous nous proposons alors de discuter ces modèles tout en présentant leurs variables explicatives et à expliquer

Abdominal Cocoon A Case Report with Short Review of Literature
Abdominal cocoon is a rare entity where there is encapsulation of the small bowel by a fibrous membrane causing clustering of the bowel. The exact aetiology is unclear. We report a case of a 15 year old girl with a history of recurrent colicky abdominal pain in the right lower abdomen. Clinical diagnosis was recurrent appendicitis. She underwent laparotomy for appendicular lump. Histopathological examination of the resected lump grossly and histologically revealed the features of abdominal cocoon. Key Words: Abdominal Cocoon; Sclerosing encapsulating peritonitis; Small bowel. DOI: 10.3329/bsmmuj.v2i2.4763 BSMMU J 2009; 2(2): 81-8
Fetal outcome of placenta accreta spectrum disorder patients admitted at Cumilla medical college hospital
Background: Placenta accreta spectrum disorder (PASD) is a complex obstetric condition associated with significant maternal and fetal morbidity and mortality. Despite its increasing global prevalence, there is limited research focusing on the fetal outcomes of PASD patients, particularly in Asian populations
Methods: This observational study was conducted at Cumilla medical college hospital over 18 months, starting from January 2022. A total of 60 patients diagnosed with PASD were included, following specific inclusion and exclusion criteria. Data were collected on sociodemographic characteristics, antenatal care, presenting complaints, and fetal outcomes.
Result: The study found that 90% of the participants had live births, while 10% experienced intrauterine death. Among the live births, there was a nearly equal distribution between low and normal birth weights. The sociodemographic distribution was diverse, with the majority of participants falling within the age range of 21-30 years. Half of the participants received regular antenatal care, and antepartum hemorrhage was the most common presenting complaint.
Conclusions: The study provides valuable insights into the fetal outcomes of PASD patients, with a notably high rate of live births. The findings also highlight the importance of regular antenatal care and early diagnosis in managing PASD effectively. The study serves as a foundation for future research aimed at improving both maternal and fetal outcomes in PASD.

The Potential Amoebicidal Effect of Some Milk forms as an Inhibitor for Entamoeba histolytica Viability Isolated from Diarrhea
Milk includes numerous compounds such as lacto-peroxidase, lactoferrin, immunoglobulin G, secretory immunoglobulin A, and Lysozymes The invasive trophozoites of E. histolytica are capable to inhabit host tissues and provoke diseases such as intestinal colitis. The objective of the study was to compare different forms of milk’s effect on E. histolytica trophopzoite by measuring protein concentration in vitro using a spectrophotometer and number of trophozoite by microscopy. For this purpose, E. histolytica trophozoites were exposed to several types of milk (human, sheep, cattle, goats, and formula) at concentrations of 6, 12, 18, and 24% for each type after 8, 16, and 24 hours of incubation. According to the findings, sheep and goat milk had lower total protein concentrations after 8 hours than other types of milk when compared to the control group. After 16 hours of incubation, raise the milk concentration to 24% leading to a reduction in the formula milk\u27s total protein concentration to 5g/l. after 8 and 16 hours of incubation, sheep milk and cattle have significantly lower total protein concentrations (24% vs. 8%), respectively. The action of formula and human milk is increased by 24-hour incubation. Increase the trophozoite inhibition percentage compared to metronidazole in human milk, which was followed by sheep and cattle milk with respective values of 60.9%, 56.1%, and 46.3% respectively. Human milk, goat and formula milk had the greatest inhibitory activity after incubation 24hrs. at 24%.the extent of amoebicidal activity of milk was shown to depend on incubation period and concentration of milk
A Strategy for Automatic Quality Signing and Verification Processes for Hardware and Software Testing
We propose a novel strategy to optimize the test suite required for testing both hardware and software in a production line. Here,
the strategy is based on two processes: Quality Signing Process and Quality Verification Process, respectively. Unlike earlier work,
the proposed strategy is based on integration of black box and white box techniques in order to derive an optimum test suite
during the Quality Signing Process. In this case, the generated optimal test suite significantly improves the Quality Verification
Process. Considering both processes, the novelty of the proposed strategy is the fact that the optimization and reduction of test
suite is performed by selecting only mutant killing test cases from cumulating t-way test cases. As such, the proposed strategy can
potentially enhance the quality of product with minimal cost in terms of overall resource usage and time execution. As a case study,
this paper describes the step-by-step application of the strategy for testing a 4-bit Magnitude Comparator Integrated Circuits in a
production line. Comparatively, our result demonstrates that the proposed strategy outperforms the traditional block partitioning
strategy with the mutant score of 100% to 90%, respectively, with the same number of test cases
