BACKGROUND We conducted a study of participants' abilities to place a laparoscopic port for in vivo biosensor use. Biosensors have physical limitations that make port placement crucial to proper data collection. A new port placement algorithm enabled evaluation of port locations, using segmented patient data in a virtual environment. METHODS Port placement scoring algorithms were integrated i...

The benefit of combining postoperative radiation therapy (PORT) with chemotherapy for resected patients with pancreatic adenocarcinoma is controversial. We sought to determine the effects of PORT on survival in patients with pancreatic adenocarcinoma who underwent primary site surgery. Patients with pancreatic adenocarcinoma receiving primary tumor surgery between 1988 and 2012 were identified ...

Construction of coastal ports makes port area and nearby sea area become high risk region of ecological emergency and environmental pollution. It is helpful for providing references to protect ecological environment of port by quantifying port ecological carrying capacity. This paper will transfer resources and energy consumed in port production and operation to four ecological productive lands...

Purpose This paper aims to explore the comparative analysis of marketing strategies between seaports and dry ports. Second, this proposes a recommendation improve approaches in both nodes. Design/methodology/approach research analyzes current freight volume enhance interrelation them for comprehensive collaboration supply chain. employed semi-structured interviews via an e-interview questionnai...

Significant advantages of intermodal and containerized transport have increased the global interest to this mode of transportation. This growing interest is reflected in the annual volume of container cargo growth. However, the container transport inside Iran does not have a proper place. Comparing the count of containers entering and leaving ports with the statistics obtained from railway and ...

background: the purpose of our study was to assess resident and fellow patient care competency related to chest port catheter insertion after implementation of an educational program and completion of a certification checklist. furthermore, we aimed to measure the impact of this intervention on early infection rates. methods: baseline early infection rates as defined by the cdc were obtained in...

Port competition is very often analysed and the analysis depends on the criteria that we take into consideration. In the UNCTAD [1] publications, the geographical location, hinterland networks, port tariffs, efficiency of land transport and port information system are selected as the most important criteria. Bichou and Gray [2] concluded that the port competition depends also on institutional a...

Butyltin species were measured in sediments from coastal locations in the Gulf and Gulf of Oman. Both butyltin and phenyltin species were measured in biota samples from four countries in this region. With tributyltin (TBT) concentrations up to 60 ngSng(-1), some sediments could be classified as contaminated (i.e. TBT>1.3 ngSng(-1)), namely Dukhan (Qatar), the BAPCO industrial complex and Askar ...

Sampling zooplankton is a useful strategy for observing trace hydrocarbon concentrations in water because samples represent an integrated average over a considerable effective sampling volume and are more representative of the sampled environment than discretely collected water samples. We demonstrate this method in Port Valdez, Alaska, an approximately 100 km(2) basin that receives about 0.5-2...
