title: Selection of rework measurement methodology utilizing AHP method

description: Abstract Civil construction has high rework rates, which entails additional costs and delays in project deadlines. In this way, several authors and entities have studied the problem and sought solutions to try to quantify and minimize the consequences of reworking. Several rework measurement methodologies have been developed, including: Construction Industry Institute Reduction Rework Program, Best Productivity Practices Implementation Index of the Construction Industry Institute, Methodology of the Construction Owners Association of Alberta, and Measuring and Classifying Construction Field Rework . In this context, this article aims to propose a procedure, based on the multicriteria analysis method Analytic Hierarchy Process – AHP, to assist in the process of selecting the most appropriate rework measurement methodology to be adopted in subsectors of the civil construction industry. The proposed procedure was applied to the industrial assembly segment, and the Rework Reduction Program methodology presented the best results regarding the rework measurement according to five criteria selected for analysis (coverage, deployment, costs, data entry and system operation), being the most indicated for use.

title: Morphological effects on helminth parasites caused by herbicide under experimental conditions

description: Abstract Helminth parasites have been studied as potential accumulators for different pollutants. Echinostoma paraensei is a foodborne trematode whose vertebrate host, the rodent Nectomys squamipes, is naturally exposed to environmental pesticides. However, little information exists regarding the pesticide’s effects on helminths. This study investigated the morphological effects on the trematode, E. paraensei, after experimental Roundup® herbicide exposure, in concentrations below those recommended for agricultural use. After two hours of exposure, scanning electron microscopy (SEM) showed changes to the tegument, such as furrowing, shrinkage, peeling, spines loss on the peristomic collar, and histopathological evidence of altered cells in the cecum and acinus vitelline glands with vacuoles and structural changes to the muscular layers. Glycidic content was decreased, primarily in the connective tissue. As E. paraensei is an intestinal parasite of the semi-aquatic wild rodent, N. squamipes, it is predisposed to pesticide exposure resulting from agricultural practices. Therefore, we emphasize the need to evaluate its impact on helminth parasites, due to their pivotal role in regulating host populations.

title: Repeatibility of agroindustrial characters in sugarcane in different harvest cycles

description: ABSTRACT In commercial cultivation of sugarcane, knowledge about the repetition of agroindustrial characters is essential to identify long-lived genotypes in production cycles, which when selected, will contribute to the significant increase in productivity. This work evaluated the agroindustrial performance of 16 sugarcane genotypes in the sugarcane microregion Litoral Norte of Pernambuco in four harvest cycles and the regularity in the repetition of characters. The experiment was conducted in the agricultural area of São José sugar mill, Igarassu, state of Pernambuco, Brazil. The experiment was carried out following a randomized block design with four replications. The variables evaluated were: tons of POL per hectare (TPH), tons of cane per hectare (TCH), fiber (FIB), adjusted POL% (PCC), soluble solids content (BRIX), and total recoverable sugar (TRS). The variance analysis detected significant differences among the genotypes along the four harvest seasons, indicating genetic variability and possibility of success in the selection of superior genotypes. Estimates of repeatability coefficient point to regularity in the repetition of agro-industrial characteristics allowing to identify genotypes with the highest longevity. The genotypes SP79-1011, RB863129, RB92579, RB813804, RB982559 e RB982613 presented best agroindustrial performance, and two evaluations based on TPH and TCH characters are enough to select superior genotypes with 90% predictability of their actual values.

title: Genetic diversity of populations of the dioecious Myrsine coriacea (Primulaceae) in the Atlantic Forest

description: ABSTRACT Although a species’ sexual system may influence the genetic diversity of its populations in their natural environment, there have been few such studies involving indigenous species of the Atlantic Forest. Here we study Myrsine coriacea, a dioecious tree widely used in reforestation programs despite a lack of information about its natural interpopulation genetic variation. To address this knowledge gap, intra- and interpopulation genetic diversity were measured for male and female individuals of ten natural populations using ISSR markers. Greater intrapopulation genetic diversity indicated interpopulation gene flow, regardless of isolation and distance between populations. Multivariate analyses detected significant differences in genetic diversity between populations, but not between males and females, which indicates that genetic diversity did not differ between the two sex morphs. Distance between populations was unrelated to genetic diversity. Myrsine coriacea has not experienced a loss of genetic variability despite the characteristic segregated spatial distribution of its populations. These results suggest that obligatory cross-pollination and dispersal by birds may be important mechanisms for the maintenance of genetic diversity in natural populations of M. coriacea.

title: Effects of drying and storage conditions on the stability of TSH in blood spots

description: ABSTRACT Objective To evaluate the influence of sample drying and storage temperature on TSH stability in neonatal screening. Subjects and methods Blood samples from 29 adult volunteers as a surrogate for neonatal blood (10 with normal TSH, 9 with overt hypothyroid and 10 with subclinical hypothyroidism) were spotted on filter paper and dried at 22°C or 35°C for 3 hours. The samples were then stored at 22°C, -4°C, or -20°C, and TSH measurements were performed at day 0 (D0), D7, D30, D60, D180, and D360 of storage. Results The drying temperature did not interfere with TSH measurement on D0. TSH values remained stable up to D30 when stored at 22°C and were stable up to D60 when stored in a refrigerator or freezer. Samples stored at 22°C had a greater decrease in TSH values than samples stored in a refrigerator or a freezer. Conclusions Freezer storage is not advantageous compared to storage in the refrigerator. At the end of one year, if confirmation of the initial result is required, a reduction of TSH concentrations should be taken into account.

title: Relationship between oxidative stress and inflammation in peripheral and cerebral system of oxonate-induced hyperuricemic rats

description: ABSTRACT To study what kind of role uric acid play on the relationship between oxidative Stress and inflammation in peripheral and cerebral system of oxonate-induced hyperuricemic rats. Twenty-six eight male Wistar rats were divided into two groups randomly. Potassium oxonate was used to establish hyperuricemic model for four weeks. In 2nd and 4th week, uric acid (UA) level, total superoxide dismutase (T-SOD), Gu,Zn-SOD activity and interleukin-1beta (IL-1β) concentration in serum were determined respectively. In 4th week, one hour after last PO treatment, five rats of every group were given Evans Blue to test blood-brain barrier (BBB) permeability. Other brains were obtained to analysis T-SOD, Gu,Zn-SOD activity and IL-1β concentration in cerebral system. Meanwhile, brain and kidney were stained with hematoxylin and eosin (H&E) to observe pathological change. In 2nd week, both of T-SOD and Gu,Zn-SOD activity in serum increased obviously (P&lt;0.05) in hyperuricemia rats. However, IL-1β content didn’t change remarkably. In the 4th week, T-SOD activity in model group had become similar with control group, and at the same time IL-1β content in serum increased significantly (P&lt;0.05). Pathological section showed the structural and functional unit of the kidney had been damaged. On the contrary, both of T-SOD and Gu,Zn-SOD activity in brain increased obviously (P&lt;0.05), but IL-1β concentration was no significant difference between two groups. In addition, the results of Evans Blue and H&E suggested the integrity of BBB and structure of brain were not changed after PO treatment. The permeability of BBB and form of UA would be potential factors to decide what kind role UA play on keeping balance between anti-oxidative stress and induction of inflammatory response.

title: Gas exchanges and production of colored cotton irrigated with saline water at different phenological stages

description: ABSTRACT Scarcity of good-quality water is a limiting factor for irrigated agriculture, especially in semi-arid regions, which leads to the use of water with high salt content to irrigate crops. Therefore, this study aimed to evaluate physiological aspects and production of colored cotton genotypes under saline stress, during the different development stages and under conditions of low and high salinity. The experiment was conducted using a randomized block design, with a 3 × 7 factorial scheme and three replicates. Treatments corresponded to three colored cotton genotypes irrigated with low-salinity water (0.8 dS m-1) and high-salinity water (9.0 dS m-1): T1-A1B1C1, T2-A2B1C1, T3-A1B2C1, T4-A1B1C2, T5-A2B1C2, T6-A2B2C1 and T7-A1B2C2 (A1, B1 and C1: without salinity and A2, B2 and C2: with salinity; in the vegetative, flowering and fruiting stages, respectively). Among the genotypes, BRS Rubi was the most sensitive to irrigation water salinity, regardless of development stage. Successive application of saline water at the flowering and boll formation stages led to drastic reduction in physiological aspects of the crop, with recovery of the plants after the stress was interrupted. Saline water irrigation at initial development stages can be used in the cotton crop for reducing the average time to the beginning of flowering. Seed cotton production was more affected by application of saline water at the flowering and boll formation stages.

title: Microscopic aspects of electrosensory system on the partially euryhaline lesser guitarfish

description: ABSTRACT The electrosensory system on elasmobranchs consists of subcutaneous electroreceptor organs known as ampullae of Lorenzini. The present study investigated the ampullae of Lorenzini morphology of the lesser guitarfish Zapteryx brevirostris, using light microscopy and scanning electron microscopy. The pore number found in the ventral skin surface is much higher than that found in the dorsal portion, characteristic of species that inhabit the euphotic zone. Under light microscopy it was possible to observe that the wall canal consists of a single layer of squamous epithelial cells. The canal features distal expansion, where the ampullae are located with up to six alveoli. The sensory epithelium of ampullae is composed by cubic cells, with oval nucleus, restricted to the interior of the alveoli. With analysis the clusters under scanning electron microscopy, it was possible to observe the structure and the random arrangement of individual ampullae, canals and nerves. The distribution of dorsal and ventral pores and ampullae in Z. brevirostris resembled those of the same family. The number of alveoli per ampullae was similar to that found in euryhaline elasmobranchs species, suggesting that the morphological organization in Z. brevirostris is linked to its possible evolutionary transitory position among batoids.
