Concentrations of lead, copper, cadmium, and mercury were determined in sediments and two selected marine organisms (Cynoglossus arel and Panulirus homarus) collected from Jask Port, Darak Port, Pozm Port, Gulf of Chabahar and Gowatr Port in the north coasts of the Oman Sea during pre (spring) and post (autumn) monsoon in 2017. Heavy metals concentrations were determined by atomic absorption sp...

This research uses computational modeling to explore another method to increase diesel engine performance while maintaining low pollutant emission levels. Previous studies have shown that injection-rate profiles and injector configurations play important roles on the performance and emissions of particulate and NOx in DI diesel engines. Since the most important engine design parameters, includi...

Background and objectives: The study was conducted with the aim to determine frequency and to assess the risk factors of portsite infection after elective laparoscopic cholecystectomy in low-risk patients at a tertiary care hospital of Kashmir.Design and Setting: Prospective.Patients and Methods : The study included 675 consecutive patients of port-site infection after elective laparoscopic cho...

Border ports play a substantial role in socio-economic exchanges, which reflect the diplomatic relations between neighboring countries. This paper maps and analyzes the evolution process of border ports in China since the 1930s, in terms of the spatial distribution, transport modes, cargo and flows of people. Four development modes of border ports and cities are summarized based on the function...

Objective: To evaluate the feasibility and safety of single-port laparoscopic hysterectomy comparing with multi-port laparoscopic hysterectomy in treatment of benign uterine diseases. Methods: Data were collected retrospectively by review of the medical records of 252 patients who underwent multi-port or single-port laparoscopic surgery for treatment of benign gynecologic diseases. Laparoscopy ...

BACKGROUND Postoperative radiation (PORT) is an option for non-small cell lung cancer (NSCLC) patients with resectable stage IIIA pathological N2 status (pN2). For patients with PORT, this study aims to investigate the impact of the exact number of positive lymph nodes (LNs) on overall survival (OS) and lung cancer-specific survival (LCSS). METHODS Within the Surveillance, Epidemiology, and E...

in this study, to determine the economic value of irrigation water and simulate the response of farmers to reducing  available water policy of positive mathematical programming models (pmp) was used. by the proposed model, the economic value (shadow price) of irrigation water estimated in each of the areas of western rodbar alamuot, rajai dasht and eastern rodbar almuot. then, the reactions of ...

ion. For an abstraction, T (λx.t) is obtained by introducing an agent λ, and simply linking its right auxiliary port (called body port) to the root of T (t) and its left one (variable port) to the unique wire corresponding to x in T (t). If x does not appear in t, then the left port of the agent λ is linked to an agent (for erasure).

The Port of Seville is an inland port located in the Guadalquivir River in the south of Spain and it is the unique Spanish inland port. Our research is focused on the simulation of the freight transport process beginning with the movement through the whole estuary of the river and finishing with the vessels arriving to the port dependencies, where the logistic operators’ load and unload process...
