Daily variation in the serum concentrations of insulin and insulin-like growth factor-I and in the plasma concentrations of thyroxine and triiodothyronine were evaluated in ewes fed 30%, 100% and 200% of theoretical maintenance energy requirements. The single daily meal has had significant effects (p<0.05) on almost all profiles. In general, serum or plasma hormone concentrations have increased after the meal, in particular at the two higher levels of energy intake. In the group submitted to the lowest level of energy intake, the consequences of the meal on circulating levels were almost imperceptible. The effects of feeding levels on serum or plasma concentrations have widely varied among hormones, not showing any objective pattern or relationship. Because these variations may affect the interpretation of these blood indicators, knowledge of daily profiles and of the effect of feed level must be considered. In order to maximize the diagnostic value of those indicators, the most suitable times for blood collection seem to be 16 h after the meal and (or) just before the meal. The collection 16 h after the meal apparently allows the characterization of a relatively steady metabolic state, intermediate between the close effects of food intake and the final phase of the intensification of body reserves mobilization. The collection just before the meal will give a good indication of the level of activity of those mobilization mechanisms.

Twenty eight non-lactating and non-pregnant adult Serra da Estrela ewes, ranging in body condition score (BCS) from 1 to 4 were used to study the relationships between BCS, live weight (LW), body composition and fat partition. Ewes were slaughtered and their kidney knob and channel fat (KKCF), sternal fat (STF) and omental plus mesenteric fat (OMF) were separated and weighed. Left sides of carcasses as well as the respective lumbar joints were then dissected into muscle, bone and subcutaneous (SCF) and intermuscular fat (IMF). The relationship between LW and BCS was studied using data from 1,396 observations on 63 ewes from the same flock and it was found to be linear. Regression analysis was also used to describe the relationships among BCS and/or LW and weights (kg) and percentages in empty body weight (EBW) of dissected tissues. The prediction of weights and percentages in EBW of total fat (TF) and of all fat depots afforded by BCS was better than that provided by LW. Only the weight of muscle and the percentage of bone in the EBW were more efficiently predicted by LW than by BCS. IMF represented the largest fat depot with a BCS of 1 and 2, whereas SCF was the most important site of fat deposition with a BCS of 3 and 4. Allometric coefficients for each fat depot in TF suggest that the fat deposition order in ewes from this breed is: IMF, OMF, SCF and KKCF. Results demonstrate that BCS is a better predictor than LW of body reserves in this breed and that LJ is a suitable anatomical region to evaluate BCS.

Background: This study retrospectively compares the clinical outcomes of excision of dorsal cysts of the wrist by open and arthroscopic approaches, considering three variables: recurrence rates, residual pain, and the time required for patients to return to their work activities. Methods: All patients who submitted to open or arthroscopic surgical excision of wrist ganglions between January 2012 and December 2017 were evaluated with a mean follow-up period of 44 months. Preoperative and postoperative pains were evaluated using a visual analogue scale, and functional outcomes were evaluated using the Disabilities of the Arm, Shoulder and Hand (Quick-DASH) questionnaire. Recurrences were confirmed by clinical examination, ultrasound, or magnetic resonance imaging. Results: Our study showed that there are no statistically significant differences between the two surgical techniques regarding the recurrence rate or residual pain. Conclusion: Patients who underwent arthroscopic surgery had a statistically significant early return to work.

Modeling and simulation techniques are a necessity to solve the problems and aid the automated driving verification and validation process. The scenario-based analysis like hazard analysis and risk assessment is counting as an essential method not only to understand the system behavior in the field of an automated vehicle but also to reduce the development and communication gaps. In terms of functional safety and safety of the intended functionality the number of hazardous scenarios increases that need to be reduced. Scenario reduction is a challenge that yet needs to be solved. Therefore, this paper proposes a probability approach like the Monte Carlo method at the logical scenario level. Additionally, the safety-critical vehicle parameter range has been optimized based on collision detection. Furthermore, the result realized by the Monte Carlo experiment has been used to model the concrete scenarios in CarMaker in a time-efficient manner. The approach of modeling for a specific function like transverse guidance can be utilized to build a full scenario database for the highly automated driving vehicle.
Sand-Nonwoven geotextile interfaces shear strength by direct shear and simple shear tests
Vieira, Castorina Silva,Lopes, Maria de Lurdes,Caldeira, Laura Techno-Press 2015 Geomechanics & engineering Vol.9 No.5
Soil-reinforcement interaction mechanism is an important issue in the design of geosynthetic reinforced soil structures. This mechanism depends on the soil properties, reinforcement characteristics and interaction between these two elements (soil and reinforcement). In this work the shear strength of sand/geotextile interfaces were characterized through direct and simple shear tests. The direct shear tests were performed on a conventional direct shear device and on a large scale direct shear apparatus. Unreinforced sand and one layer reinforced sand specimens were characterized trough simple shear tests. The interfaces shear strength achieved with the large scale direct shear device were slightly larger than those obtained with the conventional direct shear apparatus. Notwithstanding the differences between the shear strength characterization through simple shear and direct shear tests, it was concluded that the shear strength of one layer reinforced sand is similar to the sand/geotextile interface direct shear strength.

Parasitic infections (PIs) remain a public health concern among school-age children living in areas of greater socioeconomic vulnerability, especially in Brazil, Russia, India, China, and South Africa. PIs can promote nutritional deficiencies, increasing the risk of anemia and impaired physical and cognitive development. Thus, fortified foods have been considered as a promising strategy for improving the nutritional status of children and preventing PI complications. This systematic review aimed to present the effects of iron-fortified foods for deworming and improving blood parameters in schoolchildren residing in areas that are vulnerable to PIs. This review is based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines of randomized clinical trials addressing the use of fortified foods and micronutrients in children living in areas endemic for PIs. The PubMed, LILACS, Scopus, and Cochrane databases were searched to identify articles published between 2000 and 2020. A total of 153 records were retrieved from the databases, 10 of which were considered eligible for this study. On the basis of our analysis, most of the selected studies showed that the inclusion of fortified foods in the diet improved blood and infectious parameters. Therefore, fortified foods can be used as an important tool for controlling the adverse outcomes of PIs among children living in areas of greater vulnerability. However, more studies on this topic are needed to provide more evidence and consolidate strategies using iron-fortified food.
