In the present investigation, gross and microscopic lesions of the ovaries were studied in two hundred and ten (210) adult non-pregnant she-camels. Fresh samples of ovaries were collected from she-camels at the point of slaughter in Al-Ahsa abattoir, Eastern region of Kingdom of Saudi Arabia. These samples were subjected to histopathological studies and stained by routine Hematoxylin and Eosin stain. Grossly, of the 210 ovarian tissues examined, 30 (14.28%) had ovarian lesions of one type or another, whereas 180 (85.71%) camels were apparently healthy. Only 6 (2.85%) ovaries showed unilateral ovarian hypoplasia, whereas 4 (1.9%) showed bilateral ovarian hypoplasia. Cystic ovaries were observed in a total of 13 of the collected samples of ovaries, of these 8 (3.8%) were diagnosed as follicular cystic ovaries, while 5 (2.38%) were luteal cystic ovaries. Ovarian abscess appeared in only one sample of the collected ovaries. While ovarian tumors were observed in a total of 6 of the collected samples distributed as, two fibromas, three dermoid cysts, and only one hemangioma. The present study indicates that follicular cysts, luteal cysts and ovarian hypoplasia were the most common ovarian disorders in non-pregnant she-camels in Al-Ahsa region of the Eastern Province of Kingdom of Saudi Arabia.

Bacterial cellulose (BC) is a versatile biomaterial with unique properties that make it promising for various biomedical applications, including wound healing. The extracellular matrix (ECM) plays a crucial role in wound healing, providing a structural scaffold and signaling cues for cell migration and proliferation. This study investigates the potential of BC as a scaffold for ECM production and its effect on in vivo wound healing. In this work, the bacterial cellulose fermentation process is modified by the addition of Green Propolis and Usnic acid to the culture medium and natural materials before the bacteria are inoculated. In vivo behaviour using natural membranes for regenerative medicine is presented and it is in edit. Overall, our findings demonstrate the potential of BC as a scaffold for ECM production and its beneficial effects on in vivo wound healing. BC-based dressings may offer a novel approach to promoting wound healing and tissue regeneration in clinical settings. Further studies are warranted to optimize BC-based therapies and explore their full potential in regenerative medicine.

This paper proposes an efficient scheme to reduce the pre-correlation bandwidth effect in the global navigation satellite system(GNSS)receiver filtering *** is mainly based on the application of a spectral transformation to the satellite-emitted signal that effectively reduces its *** the receiver's end,this operation causes the spreading of noise over a much wider band than that used by the radio frequency ***,the resulting auto-correlation function in the acquisition process acquires properties that enhance considerably the performance of the receiver in the presence of the multipath and noise disturbing *** simulation results demonstrate that the proposed method is a plausible solution for both multipath and noise problems in the GNSS applications for any limited value of the pre-correlation bandwidth in the receiver filter.

Background: Early excision and grafting has been the preferred method of managing major burns around the world since 1970. Considering the advances in health care and the development of new antibiotics over the past 50 years, delayed grafting as a technique for the management of burns over 15%-20% of total body surface area (TBSA) could have comparable results to that of early excision. This study aims to highlight the outcomes of practicing delayed grafting in burn patients. Methods: A case series analysis was performed of 51 patients who were admitted to the burns unit in Sultan Qaboos Hospital Salalah with over 20% TBSA between January 2014 and December 2019. The patients received prophylactic antibiotics and silver sulphadiazine dressing until the burn eschar had completely separated, followed by grafting. Results: Two patients were lost during the entire duration of the study. The mortality rate was comparable to that of early excision, while the rate of hypertrophic scarring was lower than the range reported by other studies. Conclusion: In the management of patients with over 20% TBSA, delayed grafting after complete separation of eschar is still a valid technique.

In framework of the fictitious domain methods with immersed interfaces for the elasticity problem,the present contribution is to study and numerically validate the jump-integrated boundary conditions method with sharp interface for the vector elasticity system discretized by a proposed finite volume *** main idea of the fictitious domain approach consists in embedding the original domain of study into a geometrically larger and simpler one called the fictitious ***,we present a cell-centered finite volume method to discretize the fictitious domain *** proposed method is numerically validated for different test *** work can be considered as a first step before more challenging problems such as fluid-structure interactions or moving interface problems.

To investigate age and sex distribution of vasovagal syncope （VVS） patients undergoing head-up tilt table test （HUTT） at a tertiary hospital. The details of syncope patients who underwent HUTT at our department of cardiac function from January 2004 to December 2010 were reviewed. Of the 1 799 patients who underwent the HUTT, 854 tested positive, of which 558 （65.3%） were women, which were more than the women in the negative group （450, 47.6%）（p〈0.05）. VVS patients showed a bimodal age distribution between 11 and 20 years of age and in the fourth decade. In almost all age groups, mixed response was the highest compared with vasodepressor and cardioinhibitory. VVS patients who underwent HUTT indicate bimodal distribution peaking before the second decade and the fourth decade. The incidence of females was twice that of males before the sixth decade, and old age occupies a small percentage of VVS with no other comorbidities.

The Luconia Province-offshore Sarawak-is a key geological unit for understanding the distribution of hydrocarbon resources in Malaysia. Nevertheless, little effort has been made to address the palaeoenvironmental characteristics of the Tertiary carbonates in the key sector of Central *** study the sedimentology and petrography of core samples from a well in Central Luconia, for which thirteen microfacies have been identified reflecting different depositional settings. This is the first microfacies scheme elaborated for Luconian carbonates. Lithofacies and microfacies distribution are compatible with deposition in a reef complex, originating around a framework reef, within the euphotic zone. Sediments were deposited in environments of backreef, reef crest, and forereef. The fair weather wave base is marked by the presence of coralline red algae, foraminifera, decreasing degree of bioclast fragmentation and other microfacies features. As a result, a depositional-environmental model is constructed, depicting a reef complex built around a framework reef developed on the margin of an isolated platform. In addition, an innovative, preliminary time series analysis of facies, microfacies and depositional environment data reveal the existence of seasonal cycles in the stacking patterns of facies and microfacies.

The progression through which a person acquires ,;kills, understanding, and opinions regarding a particular organization or company is called organizational learning （OL）. In this study, the connection between organizational innovation （OI） and OL within the inf3rmation and communication technology （ICT） industry in Malaysia is surveyed. These relationships are examined, because various previous inquiries have shown that an imperative precursor to firm performance is OL. Two hundred and seventy-eight surveys were completed by small and medium organizations across Malaysia. The connections existing between the causes of OL and the causes of OI were ascertained by using structural equation modeling （SEM）. Amongst the Malaysian small- and medium-sized enterprises （SMEs） that participated in fire study, OI and OL are considerably linked.
