Malignant mesothelioma (MM) is extremely aggressive and a typical refractory cancer. In this study we investigated how effective on killing MM cells by carbon ion beam alone or in combination with cisplatin (CDDP) in vitro. Carbon ion beam (at the center of SOBP with 50 keV/µm of average LET) dose-independently suppressed MM cells MESO-1 and H226 cell viability and in combination with CDDP (25 ...

Specifically W-labeled fatty acids and 2-amino-4-phenylbutyric acid were administered to fed and starved normal and nonketotic and ketotic diabetic rats. The acetylated amino acid was isolated from their urines, hydrolyzed, and the resulting acetates degraded. The percentage of distribution of 14C! in the acetate from [2-Wlstearate and [2W]palmitate formed by the nonketotic diabetic rats was ab...

Objectives—To assess respiratory morbidity over several cross sectional phases in the European carbon black manufacturing industry. Methods—Participants completed an amended (and translated) MRC respiratory morbidity questionnaire with additional questions on previous exposures, job history, etc, and spirometry traces in each phase. Concurrent with the health outcome measures, personal exposure...

Closing carbon mass balances is a critical and necessary step for verifying the performance of any conversion process. We developed a methodology for calculating carbon mass balance closures for a cellulase production process and then applied measurement uncertainty analysis to calculate 95% confidence limits to assess the accuracy of the results. Cellulase production experiments were conducted...

In the first, cadmium selenide nanoparticles loaded on activated carbon (CdSe-NP-AC) has been synthesized. Then, this new adsorbent successfully has been applied for the removal of fluoride from aqueous solution in batch studies, while the effect of various experimental parameters like initial pH, contact time and temperature on its removal percentage was examined by one at a time optimization ...

Recently, polymeric nanocomposites have been used as real-time detectors and dosimeters of gamma radiation. In this experimental work, multi-wall carbon nanotubes (MWCNT) were dispersed in polystyrene (PS) martix with a weight percentage of 0.05 wt%. SEM images confirmed the appropriate and uniform distribution of carbon nanotubes in the polymer matrix. The dark current and photocurrent of the ...

Awareness of the effects of fire on various aspects of an ecosystem after the fire,is important for range management. Changes in soil physical and chemical propertiescaused by fire can be the cause of changes in the vegetation. In this study, effects of fire onphysical and chemical characteristics of soil were investigated. This research was carriedout in a randomized block design method in the...

Shoot tips of two fig cultivars (Conadria and Black Mission) proliferated in vitro, were cultured on modified MS medium supplemented with 0.5 mg/l 6-benzylaminopurine (BAP). The present investigation aimed to investigate the effect of different medium salt strengths (Double, full, half and quarter) and different sources of carbon (sucrose and fructose) at different concentrations (0.1 and 0.2 m...

Environmental sustainability of a supply chain depends on the purchasing strategy of the supply chain members. Most of the earlier models have focused on cost, quality, lead time, etc. issues but not given enough importance to carbon emission for supplier evaluation. Recently, there is a growing pressure on supply chain members for reducing the carbon emission of their supply chain. This study ...

Present research was conducted with the aim of determination of significant effect of soil properties on natural regeneration of Haloxylon aphyllum and correlation coefficient and linear relation between soil variables and natural regeneration of Haloxylon aphyllum. Firstly, geomorphologic units were prepared in the areas under cultivation of Haloxylon aphyllum in Ardestan. Two cultivated lands...
