The rice crop and associated ecosystems constitute a rich mosaic of habitats that preserve a rich biological diversity. Spiders are an abundant and successful group of natural predators that are considered efficient in the biocontrol of the major insect pests in agroecosystems. Spider diversity in different stages of the rice crop growth from eastern Uruguay was analysed. Field study was developed on six rice farms with rotation system with pasture, installed during intercropping stage as cover crop. Six rice crops distributed in three locations were sampled with pitfall and entomological vaccum suction machine...

The electronic structure of semiconducting carbon nanotubes selected through polymer functionalisation is routinely verified by measuring the spectral van Hove singularity signature under ultraclean vaccum conditions. Interpreting the effect of unperturbed polymer adsorption on the nanotube energetic bands in solvent media, is experimentally challenging owing to solvent molecular crowding around the hybrid complex. Here, liquid-based scanning tunneling microscope and spectroscope operating in a noise-free laboratory is used to resolve the polymer-semiconducting carbon nanotube-underlying graphene heterostructure in the presence of encompassing solvent molecules...

A well-defined silica-supported molybdenum dioxo species, ([triple bond, length as m-dash]SiO)2Mo(O)2, is prepared by grafting Mo(O)2[OSi(OtBu)3]2 on partially dehydroxylated silica SiO2-700, followed by thermal treatment under high-vaccum and calcination. Activated by an organosilicon agent the resulting material is active for olefin metathesis at 30 °C.

The quality of maternity care in the United States is variable, and access to care is tenuous for rural residents, low-income individuals, and people of color. Without accessible, timely, and high-quality care, certain clinical and sociodemographic characteristics of individuals may render them more vulnerable to poor birth outcomes. However, risk factors for poor birth outcomes do not occur in a vaccum; rather, health care financing, delivery, and organization as well as the policy environment shape the context in which patients seek and receive maternity care...

Freestanding LiCoO2/multiwall carbon nanotube/nanocellulose fibril (LCO-MWCNT-NCF) electrodes are fabricated by a vacuum filtration technique. The electrode has a high LCO loading of 20 mg/cm(2) with excellent flexibility, uniform material distribution, and low surface resistivity. When coated with 2 ALD cycles of AlF3, LCO-MWCNT-NCF has a high specific capacity of 216 mAh/g at 4.7 V. The freestanding AlF3-coated electrode preserves 75.7% of its initial capacity after 100 cycles and 70% after 160 cycles of charge discharge...

BACKGROUND: Current transfemoral prosthetic sockets are problematic as they restrict function, lack comfort, and cause residual limb problems. Development of a subischial socket with lower proximal trim lines is an appealing way to address this problem and may contribute to improving quality of life of persons with transfemoral amputation. OBJECTIVES: The purpose of this study was to illustrate the use of a new subischial socket in two subjects. STUDY DESIGN: Case series...

This study aims to demonstrate the possible relationship between the insulin-like growth factor (IGF) system and early miscarriage in polycystic ovarian syndrome (PCOS) patients with euploid embryos. 40 pregnant women included. 9 had PCOS and miscarried; 20 had PCOS and a successful ongoing pregnancy; the remaining 11 women did not have PCOS and miscarried. An ultrasound scan was performed to prove clinical pregnancy and a blood sample was taken on day 55 ± 4 of gestation. Serum samples of IGF-1, insulin-like growth factor binding protein-1 (IGFBP-1), total testosterone, serum hormone binding protein (SHBG), leptin and soluble leptin receptor (sOb-R) were obtained...

A vesicocutaneous fistula is an abnormal communication from the bladder to the skin (Pritts et al, 2001). Recently, wound vacuum-assisted closure (VAC) has been used to facilitate fistula closure. There are no reports of using VAC to help fistula closure in the pediatric population. We present a case of an adolescent patient who develops a vesicocutaneous fistula after bladder augment cystoplasty and was treated with VAC only.

The interface between organic semiconductor and graphene electrode, especially the structure of the first few molecular layers at the interface, is crucial for the device properties such as the charge transport in organic field effect transistors. In this work, we have used scanning tunneling microscopy to investigate the poly (3-octyl-thiophene) (P3OT)-graphene interface. Our results reveal the dynamic assembling of P3OT on single layer graphene. As on other substrates the epitaxial effect plays a role in determining the orientation of the P3OT assembling, however, the inter-thiophene distance along the backbone is consistent with that optimized in vaccum, no compression was observed...

OBJECTIVE: To discuss the effectiveness of free anterolateral thigh flap pedicled with medial sural vessels for treatment of leg skin and soft tissue defects. METHODS: Between July 2008 and January 2014, 32 cases of serious skin and soft tissue defects in the leg were repaired by using free anterolateral thigh flap pedicled with medial sural artery and vein. Of them, there were 22 males and 10 females, aged 23 to 50 years (mean, 36.5 years). Defects were caused by traffic accidents injury in 9 cases, crash injury of heavy object in 15 cases, and machine twist injury in 8 cases...

PURPOSE: To identify pathological features for sample analysis of magnetic resonance imaging-guided vaccum-assisted breast biopsy (MRIgVaBB) to optimize radio pathological correlation and identify discordant benign result. MATERIAL AND METHODS: Databases of two centres were queried to identify MRIgVaBB performed between January 2009 and February 2013. A cohort of 197 women (mean age: 54.5 years (24-77)) with 208 lesions was identified. We retrospectively analyzed all prebiopsy MRI examinations according to the new BI-RADS lexicon, and all biopsy samples to describe the lesion of interest, its interface with the surrounding breast tissue and other associated features...

In this work, steam explosion was used a pretreatment method to improve the conversion of elephant grass (Pennisetum purpureum) to cellulosic ethanol. This way, enzymatic hydrolysis of vaccum-drained and water-washed steam-treated substrates was carried out with Penicillium echinulatum enzymes while Saccharomyces cerevisiae CAT-1 was used for fermentation. After 48 h of hydrolysis, the highest yield of reducing sugars was obtained from vaccum-drained steam-treated substrates that were produced after 10 min at 200 °C (863...

It is of great importance to investigate the extraction of polycyclic aromatic hydrocarbons (PAHs) in plant root apoplast solution for elucidating the mechanisms underlying root absorption and translocation of PAHs and their control. However, little information is available on the extraction of plant root apoplast solution to date. In this study, wheat was employed and phenanthrene was used as the representative of PAHs. Phenanthrene extracted from wheat root apoplast solution increased with increasing vaccum degree, vacuum time, centrifugal speed and centrifugal time...

In order to study the discharge process of vacuum arc ion source, make a detail description of the discharge plasma, and lay the foundation for further research on ion source, atomic emission spectrometry was used to diagnose the parameters of plasma produced by vaccum arc ion source. In the present paper, two kinds of analysis method for the emission spectra data collected by a spectrometer were developed. Those were based in the stark broadening of spectral lines and Saba-Boltzmann equation. Using those two methods, the electron temperature, electron number density and the ion temperature of the plasma can be determined...

BACKGROUND: Cervical priming agents mainly prostaglandins in different doses and routes are used during first trimester vaccum aspiration to prevent cervical injury and shorten the abortion procedure. This study was carried out to assess women's acceptability, the efficacy and side effects of oral versus vaginal administration of misoprostol in facilitating cervical dilatation prior to first trimester vaccum aspiration. METHODS: A randomised control study where 120 women were divided in oral (51) and vaginal (69) group...
