title: Prospective evaluation of the effect of adherent perinephric fat on outcomes of robotic assisted partial nephrectomy following elimination of the learning curve

description: ABSTRACT Purpose: To prospectively evaluate the association of adherent perinephric fat (APF) on perioperative outcomes of robotic-assisted partial nephrectomy (RAPN) following elimination of the surgical learning curve. Materials and Methods: 305 consecutive RAPNs performed by a single experienced surgeon were analyzed. The first 100 RAPNs were considered the learning curve and therefore excluded. APF was defined as the necessity of subcapsular renal dissection to mobilize the tumor from surrounding perinephric fat. Perioperative outcomes were evaluated including operative time, warm ischemia time (WIT), postoperative complications, length of stay, margins, ischemia, and complications score (MIC), estimated blood loss (EBL), and change in pre-operative to postoperative day 1 (POD 1) laboratory values. After correction for multiple comparisons, P values ≤0.0045 were considered statistically significant but associations with P values ≤0.05 were also mentioned in the study results. Results: Fifty-eight (28.3%) patients had APF. Patients with APF had longer operative times compared to those without APF (median, 213 vs. 192 minutes, P &lt;0.001). There was some evidence of higher increase in change in creatinine from preoperative to POD 1 among those with APF compared to those without APF, although this was not statistically significant (median, 0.2 vs. 0.1mg/dL, P=0.03). There were no other statistically significant associations between presence of APF and perioperative outcomes. Conclusions: APF is associated with increased operative time but no change in other perioperative outcomes. Surgeon experience does not affect perioperative outcomes associated with APF.

title: Effect of Scanning Speed on the Surface Roughness of Laser Metal Deposited Copper on Titanium Alloy

description: This paper reports on the effect of scanning speed on the laser deposited Cu on titanium alloy substrate. The experiments were conducted by varying the scanning speed from 0.3 m/min to 1.2 m/min while the laser power, the powder feed rate and the gas flow rate were kept constant. The laser deposited Cu were characterized through the evolving microstructure and surface roughness. Dendrites and acicular were much pronounced in the clad area; found to decrease as the scanning speed increases due to the laser interaction time and the cooling rate. These however, influenced the irregularities in the peaks and valleys of the surface texture. The arithmetic mean deviation, Ra were measured and abridged from 6.70 µm to 1.41 µm as the scanning speed was increased from samples DC1 to DC4. The motivation for this work is to improve the surface performance of Ti6Al4V alloy when exposed and attacked by marine microfouling organisms.

title: Estimation of mercury released from an abandoned gold mine in Minas Gerais, Brazil

description: Abstract Mining is very important to the economic, political and social development of the Minas Gerais State in Brazil ever since the time the country became a Portuguese colony in the early 1500s. However, few researches have been conducted to evaluate the environmental impacts associated with the mining activity at this time. There are many abandoned mines in Minas Gerais; these are mainly gold mines inherited from the colonial period, which have been considered to represent a considerable environmental liability. However, when a road was constructed in a rural area of the municipality of Descoberto, Minas Gerais, in 2002, a significant amount of mercury was detected in an abandoned gold mine. In 2014, the State Public Prosecutor's Office found both the State of Minas Gerais and the State Environmental Agency liable and responsible for this occurrence and ordered them to design an intervention project for the contaminated area that involved mine closure. This article provides information on how mercury contamination occurred and estimates the amount of mercury present in the contaminated area, with the aim of supporting proposals of alternative remediation, monitoring and management therein. This study includes a historical survey of mining operations in the region and a brief history of the use of mercury in amalgamation. Estimations are made of the amount of gold produced and the amount of mercury released into the environment between 1850 and 1892. Results show an estimated mass of 820 kg of mercury contained in soils and sediments within an area smaller than 1 hectare.

title: Reference sample size for multiple regression in corn

description: Abstract: The objective of this work was to determine the number of plants required to model corn grain yield (Y) as a function of ear length (X1) and ear diameter (X2), using the multiple regression model Y = β0 + β1X1 + β2X2. The Y, X1, and X2 traits were measured in 361, 373, and 416 plants, respectively, of single-, three-way, and double-cross hybrids in the 2008/2009 crop year; and in 1,777, 1,693, and 1,720 plants, respectively, of single-, three-way, and double-cross hybrids in the 2009/2010 crop year, totaling 6,340 plants. Descriptive statistics were calculated, and frequency histograms and scatterplots were created. The sample size (number of plants) for the estimate of the β0, β1, and β2 parameters, of the residual standard error, the coefficient of determination, the variance inflation factor, and the condition number between the explanatory traits of the model (X1 and X2) were determined by resampling with replacement. Measuring 260 plants is sufficient to adjust precise multiple regression models of corn grain yield as a function of ear length and ear diameter. The Y = -229.76 + 0.54X1 + 6.16X2 model is a reference for estimating corn grain yield.

title: Growth and chrome content of castor bean plants cultivated in soil with application of tannery residues and coal mining waste

description: ABSTRACT The production of waste has been increasing in direct proportion to the industrialization of the countries. Therefore, the adequate disposal of these wastes is an issue widely discussed among environmental agencies. Thus, the aim of this work was to study the residual effect of successive additions of tannery and coal mining waste on the chemical properties of the soil and the accumulation of chromium in castor bean plants. The treatments applied under field conditions were: T1 - control, that is, soil without fertilization; T2- soil fertilized with nitrogen-phosphorus-potassium (NPK) + limestone to reach pH 6.0; T3 - soil mixed with tannery sludge at a dose adequate to reach pH 6.0 + PK; T4 - soil receptor of twice the dose of tannery sludge used in treatment 3 + PK; T5 - soil mixed with coal residue + NPK + limestone in an amount adequate to reach pH 6.0; T6 - soil mixed with coal residue + tannery slurry at a dose adequate to reach pH 6.0 + PK; T7 - soil mixed with chrome sawdust + NPK + limestone in adequate quantity to reach pH 6.0; T8 - soil mixed with mineral Cr + tannery sludge at a dose adequate to reach pH 6.0 + PK. In the field, the soil received the different treatments. Subsequently, samples of this soil were conditioned in pots and the experiment with the plants was conducted in a completely randomized design, with three replicates per treatment. Subsequently, samples of this soil were placed in pots and the experiment with plants was conducted in a completely randomized design, with three replications per treatment. The dry matter yield showed that the application of chrome sawdust (T7) provided the highest growth of the castor bean, as well as the higher levels of P in its tissue. Chromium content in the aerial part of the plants did not reach levels that can be considered as contamination of these plants. The distribution of chromium in the different parts of the castor bean plants demonstrated the possibility of future use of the grains to produce biodiesel.

title: Gluten-free food issues in Turkey

description: Abstract Consumption of gluten-free foods (GFFs), natural GFFs (nGFFs) or manufactured GFFs (mGFFs), is reported as a burden on GFF-consumers for different countries. In Turkey, only mGFFs are recognized to be GF, and issues related to them were investigated for the first time. Accessibility of mGFFs is too restricted. Celiac, not other gluten-linked diseases, is recognized in the institutional practices. Price of mGFFs is 5.5 times on average more expensive than corresponding gluten containing foods (cGCFs). GFF-consumers in Turkey are under a heavy burden of the high price pressure, and it is more than the burden on GFF-consumers in other countries not considering the economic welfare difference. Though, exported mGFFs are more expensive than domestic mGFFs, exported ones dominate the market. Well-established arrangements are needed for easing the burden on mGFF-consumers in the country. The lowest possible expenditure for mGFFs by celiac population is almost $ 649×106 per year excluding individuals with other gluten-linked disorders. Turkey is quite untouched market and offers lucrative business opportunities for mGFFs.

title: A Construction of Rotated Lattices via Totally Real Subfields of the Cyclotomic Field ℚ(ζp)

description: ABSTRACT The theory of lattices have shown to be useful in information theory and rotated lattices with high modulation diversity have been extensively studied as an alternative approach for transmission over a Rayleigh-fading channel, where the performance of this modulation schemes essentially depends on the modulation diversity and on the minimum product distance to achieve substantial coding gains. The maximum diversity of a rotated lattice is guaranteed when we use totally real number fields and the minimum product distance is optimized by considering fields with minimum discriminant. In this paper, we present construction of a full diversity rotated lattice for the Rayleigh fading channel in Euclidean space with full diversity, where this construction is through a totally real subfield �� of the cyclotomic field Q ( ζ p ), where p is an odd prime, obtained by endowing their ring of integers.

title: Information as a determinant criterion in the acceptance of fermented yam-based ice cream

description: Abstract The aim of this study was to evaluate the influence of information on the acceptability of fermented yam-based ice cream, as well as its sensorial profile. For this, the acceptance and check all that apply (CATA) tests were performed in two sessions by 102 tasters. In the first session, consumers received only brief information about the ice cream preparation. Additional information about the healthy contribution of the product was provided to the consumers in the second session. In the acceptance test, significant differences between the sessions were observed (p &lt; 0.05) for the flavor attribute. Information on health benefits contributed by a reduction of “dislike moderately” and “dislike very much” classes (mainly 50-80%), and an increase of “like slightly” and “like moderately” classes (mainly 30-50%) in the acceptability test in the second session. The first session, the ice cream was related to coconut water and acid flavors and sandy texture, while in the second session it was described as yogurt flavor and creamy texture. There was a tendency to assign more pleasant characteristics to the second session. Therefore, the ice cream acceptance and sensory profile described by consumers were affected by the provided information, especially for the male group.

title: The study of the guide for experiments made available in virtual repositories through inquiry-based teaching

description: Abstract: The presence of materials for education on the internet is increasing and its popularization among teachers and students has also been increasing gradually. However, such materials still require research into their conceptual and pedagogical quality. In this study, we intended to identify investigative elements in the guides for experiments in the proposed class available on the teachers’ portal of the Ministry of Education. The analysis of the investigative elements and the understanding of the organization of the guides resulted from criteria established by inquiry-based teaching and Discursive Textual Analysis, respectively. The analysis indicated that although many scripts have innovations in order to increase student participation during the experiments, the proposition of problems for the conduction of the experiments does not actually occur. These results may contribute to a reflection about the role assigned by teachers who work in Basic Education to experimentation in the teaching of Chemistry.

title: Effect of erythrosine and phloxine from xanthene food dyes on oxidative stress in Chinese hamster ovary cells

description: Abstract Objective of this study was to investigate the changes of oxidative stress parameters in Chinese hamster ovary (CHO) cells exposed to xanthene food dyes (erythrosine and phloxine), commonly-used azo dyes in the food industry. For this purpose, glutathione (GSH) and malondialdehyde (MDA) levels, glutathione peroxidase (GPx) and catalase (CAT) activity measurements of CHO cells treated with erythrosin (50 µM) and phloxine (40 µM) were compared with the control group. There was no significant difference between MDA levels in CHO cells exposed to both dyes and control group (p &gt; 0.05), however GSH levels significantly decreased with dye addition (p ≤ 0.05). An increase in GPx activity of the CHO cells exposed to phloxin was observed (p ≤ 0.05). However, there was no change in GPX activity of erythrosin-exposed CHO cells (p &gt; 0.05). In terms of CAT activity, difference between the dye-added cells and the control group was not observed. Consequently, decrease in level of GSH, which one of major antioxidant components in the cell, suggests that erythrosine and phloxine can have a toxic effect.
