Surface sediments at Lakes Fryxell, Vanda and Brownworth in the Antarctic Dry Valleys (ADV) were investigated as analogues for the cold, dry environment on Mars. Sediments were sampled from regions surrounding the lakes and from the ice cover on top of the lakes. The ADV sediments were studied using Raman spectra of individual grains and reflectance spectra of bulk particulate samples and compa...

The size distribution, number and biomass of bacteria in intertidal sediments and seawater of Ohmi Bay were investigated by the image analysis and DAPI direct count technique, in March, July and November, 1983. Bacteria with the equivalent spherical diameter between 0. 5 and 0.81am occupied 75-78% of the total populations in sediments. Mean cell volume of bacteria in sediments (0.159um3) was ab...

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...

Background: Three-por t l aparoscop ic cholecystectomy (LC) has been reported to be technically acceptable. However, whether it offers any additional advantages remains controversial. Our aim was to compare clinical outcomes of the umbilicus saving 3-port LC versus standard 4-port LC. Methods: Medical records of 55 patients to whom either umbilicus saving 3-port LC or 4-port LC was planned were...

BACKGROUND Effective and reliable venous access is one of the cornerstones of modern medical therapy in oncology. MATERIALS AND METHODS This is a prospective observational study, which collected data of patients who require "PORT" catheter insertion for any cancer, at a tertiary care oncology hospital in Ahmadabad, Gujarat, India, during a 2-year period. AIMS AND OBJECTIVES The main objecti...

We used the bacterial test on the cells called Arthrobacter globiformis in order to detect the level of toxins in the sediment of the Lake Skadar. We kept an eye on the influence of the sediments on the activity of the whole of bacterial dehydrogenase (DNA) by the process of the reduction of the oxidoreduction color of the resasurine into the resofurine. We used the organic fraction of the sedi...

Distribution and speciation of mercury (Hg) in the sediments from a tropical estuary (Godavari estuary) was influenced by the changing physico-chemical parameters of the overlying water column. The sediments from the upstream and downstream of the estuary were uncontaminated but the sediments from the middle of the estuary were contaminated by Hg. The concentrations of Hg became considerably le...

Open spaces in epithermal veins of the Bohemia mining district, Oregon, USA, filled with sediments during hydrothermal activity. These sediments consist mainly of chalcedony, rock fragments, and vein quartz fragments. In addition, hematite is deposited during stage three of the vein development. Observed sedimentary features include draping laminae, erosion surfaces, slumping, and graded beddin...

OBJECTIVES To explore the effects and feasibility of single-port video-assisted thoracic surgery (VATS) on lobectomy for pulmonary carcinoma. METHODS A total of 67 patients were enrolled in this study, in which 21 patients were treated by single-port VATS (Sing-port Group) and 46 patients by double-port VATS (Double-port Group). Blood loss, duration of thoracic drainage, length of post-operat...
