The effects of plastic mulch in Hawaiian pineapple culture on runoff generation and soil erosion are poorly understood and not covered in the literature. Field rainfall simulation experiments were conducted on an Oxisol commonly used in Hawaii for pineapple production. Four treatments were no cover (hereafter called bare), plastic mulch as the sole cover (plastic), pineapple crowns as the sole ...

geneity in ventilation be good’ [1] and the related article by Zhao and colleagues [2]. We agree with the comments that instead of incremental positive end-expiratory pressure (PEEP) levels, a decremented PEEP titration might be an attractive option for determining optimal PEEP [1,3]. However, we feel that physiological inhomogeneity in ventilation and perfusion related to the gravitational eff...

background: diabetic nephropathy (dn) is one of the most important complications of diabetes mellitus. now-a-days, cystatin c (cysc) is introduced as a new marker for diagnosis of renal damages; however, use of this marker in clinical laboratories is still controversial. the present study was aimed to evaluate the diagnostic value of serum cysc for early detection or monitoring treatment of kid...

Myelodysplastic syndromes are a heterogeneous group of clonal hematopoietic stem cell disorders characterized by persistent peripheral cytopenia with morphological and functional abnormalities of hematopoietic cells. Mast cells in ltrate into or around tumor tissues and play a role in remodeling of the stromal microenvironment, contributing to tumor progression. Increased mast cell numbers are ...

Background: Micro RNAs (miRNAs) are a pivotal part of non-protein-coding endogenous small RNA molecules that regulate the genes involved in plant growth and development, and respond to biotic and abiotic environmental stresses posttranscriptionally.Objective: In the present study, we report the results of a systemic search for identifi cation of new miRNAs in B. rapa using homology-based ...

This article provides a brief description of acute appendicitis, methods its diagnosis, discusses typical clinical cases, examples tactics for managing patients with appendicitis. The sequence management patient steps to speedy recovery the patient, including surgical interventions, his discharge positive dynamics are summarized. Special attention is paid course and further development complica...

Due to the impact of climate change, the process of salinity intrusion occurs frequently in coastal areas of Vietnam. The main objective of this study is therefore to try diff erent nanofi ltration (NF) processes (such as single-stage and dual-stage NF) to treat brackish water for residential areas in Thu Bon river basin, where the salinity varies signifi cant with seas...

We prove some simple properties of the power series ring R = Kx 1 ; x 2 ; x 3 ; : : : ]] on a countably innnite number of variables over a eld K, and of the subring R 0 generated by all homogeneous elements in R. By means of a certain decreasing ltration of ideals, which are kernels of the \truncation homomorphisms" n : R 0 ! Kx 1 ; : : : ; x n ], we endow R 0 with a topology, and show that wit...

Long time uptake arsenic will cause cancers and blackfoot disease. There are still several million people suffering from drinking arsenic ontaminated water. This work studied the performance of coupled chitosan/UF for arsenic removal and the influence of dissolved organic matter n arsenic removal with UF operation. Humic acid representing dissolved organic matter was fractionated into five grou...
