Objective: To investigate the fauna of a highly venomous marine species group, the cone snails(Family Conidae), in the shores of Qeshm Island, of evaluating the possibility of envenomation in the area and summarize recommendations for emergency first ***: Shores surrounding Qeshm Island were surveyed to collect cone snails during cold(February and March) and warm(May and June) seasons of 2017. Collected snails were identified to the species level. Abundance and species richness were estimated in shores of different structures, including muddy and sandy-rocky shores. Also, the most updated medical literature was reviewed to summarize related emergency first ***: Three cone snail species were recorded from southern sandy-rocky shores of the Island, in decreasing order of abundance, included crowned cone(Conus coronatus)(65%), feathered cone(Conus pennaceus)(28%), and frigid cone(Conus frigidus)(7%).Abundance of these species were significantly higher in cold season compared to the warm season(P < 0.05). No cone snails were recorded along the northern muddy shores of the ***: Envenomation can cause various symptoms ranging from minor local pain to systemic paralysis and death due to respiratory failure. We recommend an awareness programme for the seashore visiting public.

Powder bed fusion methods of additive manufacturing (AM) require consistent, reproducible, and uniform layers of powder for the reliable production of high-quality parts, where properties of powder are central to achieving this. Among these properties, powder flowability and spreadability play critical roles in determining the quality of these powder *** extensive research has been conducted on powder flow and spreading behaviour, and on their characterisation, there is little critical comparison and review of these terms in the context of AM. Such a review is necessary to further develop and enhance our comprehension of spreading dynamics and its relation to powder properties in AM *** review paper aims to build a coherent understanding of the correlation between powder characteristics and spreading in powder based additive manufacturing and its impact on manufactured parts. It highlights the current progress in comprehending spreading dynamics, the influence of powder characteristics, environmental conditions, spreading system, and the development of testing tools to assess powder spreadability. Furthermore, the paper critically discusses the challenge of finding appropriate quantitative metrics and recent advances in the use of standardised methods for evaluating powder spreadability.

Introduction: Worldwide specific diseases are jeopardizing people’s health in the world as well as in Iran. Chronic renal failure as a developed and irreversible failure is usually progressive. End Stage Renal Disease (ESRD) is a situation when renal function is not sufficient to preserve one’s life leading to acute uremia resulting in dialysis and/or kidney transplantation for the patients. Although dialysis methods bring about complications for the patients, peritoneal dialysis is relatively cost-effective and more convenient to survive. The present study aimed to investigate (the) Etiologic factor of renal failure and imposed complications of peritoneal dialysis in the patients of Isfahan Alzahra hospital. Materials and Methods: It was a cross-sectional descriptive study conducted on 67 patients in Isfahan Peritoneal Dialysis Center. The data from the patients were collected through a two-section questionnaire whose first section was allocated to demographic information and the second part was related to the disease and complications of peritoneal dialysis. The collected data were analyzed by SPSS version 18. Results: The findings showed that there were 39 (58%) males and 28 (42%) females. Mean age of the subjects was 48 (18.8) years old. Regarding marital status, 65% were married and 35% were single. Considering complications, 28 subjects (53.5%) had infectious complications while 24 subjects (46.2%) had non-infectious complications. The highest frequency in etiologic factor of renal failure was diabetes mellitus in 29 subjects (43.9%) and the lowest for polycystic kidney in 2 subjects (3%);in addition, hypertension was observed in 51 subjects (77.3%). Discussion: The most frequent and important complication of peritoneal dialysis catheters is infection, which may result in catheter loss and discontinuation of peritoneal dialysis (PD). Diabetes and hypertension were found as the most important etiologic factors for renal failure. They should also be considered a
