Method of formation of loading cycles for performing forced bench tests of suspension elements at the stage of technical design

Ensuring the required vehicle service life is one of the most important and topical global engineering challenges. Automobile manufacturers and research engineers around the world are actively working to improve safety and durability testing methods of vehicles, their components and systems. This article touches upon the main issues of comparing the modes of vehicle road operation and the method of forming an adequate program for extreme testing of suspension elements. The developed method has been actively applied in FSUE “NAMI” in the field of research on durability of vehicle components and systems, in particular, of hub units, with the use of mathematical modeling tools and the test base capacities and capabilities.

Beta-alanine supplementation in patients with COPD receiving non-linear periodised exercise training or neuromuscular electrical stimulation: protocol of two randomised, double-blind, placebo-controlled trials

IntroductionExercise intolerance is common in patients with chronic obstructive pulmonary disease (COPD) and, although multifactorial, it is largely caused by lower-limb muscle dysfunction. Research has shown that patients with severe to very severe COPD have significantly lower levels of muscle carnosine, which acts as a pH buffer and antioxidant. Beta-alanine (BA) supplementation has been shown to consistently elevate muscle carnosine in a variety of populations and may therefore improve exercise tolerance and lower-limb muscle function. The primary objective of the current studies is to assess the beneficial effects of BA supplementation in enhancing exercise tolerance on top of two types of exercise training (non-linear periodised exercise (NLPE) training or neuromuscular electrical stimulation (NMES)) in patients with COPD.Methods and analysisTwo randomised, double-blind, placebo-controlled trials have been designed. Patients will routinely receive either NLPE (BASE-TRAIN trial) or NMES (BASE-ELECTRIC trial) as part of standard exercise-based care during their 8-to-10 week pulmonary rehabilitation (PR) programme. A total of 222 patients with COPD (2×77 = 154 patients in the BASE-TRAIN trial and 2×34 = 68 patients in the BASE-ELECTRIC trial) will be recruited from two specialised PR centres in The Netherlands. For study purposes, patients will receive 3.2 g of oral BA supplementation or placebo per day. Exercise tolerance is the primary outcome, which will be assessed using the endurance shuttle walk test (BASE-TRAIN) or the constant work rate cycle test (BASE-ELECTRIC). Furthermore, quadriceps muscle strength and endurance, cognitive function, carnosine levels (in muscle), BA levels (in blood and muscle), markers of oxidative stress and inflammation (in blood, muscles and lungs), physical activity and quality of life will be measured.Ethics and disseminationBoth trials were approved by CMO Regio Arnhem-Nijmegen, The Netherlands (NL70781.091.19. and NL68757.091.19).Trial registration numberNTR8427 (BASE-TRAIN) and NTR8419 (BASE-ELECTRIC).

This study aimed to fi nd out factors that infl uencing costumers loyalty about murabahah fi nancing at Bank Pembiayaan Rakyat Syariah Adeco Langsa and to determine the effects partialy and silmutanously to murabahah fi ancing costumers loyalty. There are factors that infl uencing murabahah fi nancing costumers loyalty including the infl uence of service factors, facility factors, and location factors. This study used the quantitative approach. The total of respondent are 80 costumers. Sampling this study was carried through probability sampling and simple random sampling , rarely the technique of determining to selected sample without regard to the levels in the population. This study used quesioners as many as 20 items questions that were assesed with a likert 1-5 scale and used validity and reliability test. The test of assumptions were, tests of multicollinearity, heteroscedastisitas, normality, linearity then analyzed using multiple regression analysis with the determination test method F test and t test. Base on multiple regression analysis at 5% signifi cance level show that simultaneously service factors, facility factors, and location factors have signifi cant positive effect to murabahah fi nancing costumers loyalty at Bank Pembiayaan Rakyat Syariah Adeco Langsa, and then there are signifi cant positive effect of the facility factors to murabahah fi nancing costumer loyalty and the location also has a signifi cant positive infl uence on murabahah fi nancing costumer loyalty at Bank Pembiayaan Rakyat Syariah Adeco Langsa, facility factor have the most dominant infl uence on murabahah fi nancing costumer loyalty at Bank Pembiayaan Rakyat Syariah Adeco Langsa, with a signifi cance of 0,000 less than 0,05.

Convolutional Neural Networks for Leaf Disease Classification

This paper aims to improve the classification process of leaf diseases in plantations, reducing the need to have a specialist or prior knowledge of the diseases that can affect a plantation, since some diseases can spread and end with entire plantations. The proposal is the use of Convolutional Neural Networks (CNN) to classify leaf diseases in plants using images, creating a model that can be implemented in a smartphone application. The model selected for the application, using a dataset with 4485 images separated in 5 classes, had an accuracy of 97% in the test base.

Yellow bristle grass (Setaria pumila) germination biology

The presence of Setaria pumila in dairy pastures lowers feed quality and may cause grazing avoidance. More information is required about the germination biology of this weed to improve the effectiveness of control strategies. Base temperature and germination profile were determined on a thermo-gradient table. For emergence depth, seeds were buried at 0—50 mm and time to emerge recorded. Seed persistence was tracked at seven field sites over 5 years and in a laboratory-based controlled-ageing test. Base temperature for germination was 10.2˚C, germination was most rapid at 30—35˚C and most numerous from 20—30˚C. Emergence occurred from 2—50 mm depth but mostly from 2—15 mm. The controlled-ageing test indicated the seed was viable for <3 years. However, some Setaria pumila seed continued to germinate after 5 years of burial in all but the clay soil. Farmers should try to prevent this species from seeding for at least 5 years to reduce the seed bank. Soil inversion could promote dormancy and seed persistence. If followed by effective control, cultivation could stimulate germination and further reduce the seed bank.

Evaluation of the maladaptation of the test base in acrylic resin regarding the technique of preparation, place of measurement and storage time

Introduction The most used material for the preparation of the baseplates is the acrylic resin, but it can present distortions. Objective To evaluate preparation technique, region and storage time that presents less maladaptation of the base when made with self-cured acrylic resin. Material and method Models were created in gypsum type III simulating edentulous maxilla, as divided into 3 groups (n = 10): GC (control group) thermopolymerizable acrylic resin; G1 - manual adaptation technique and G2 - drip technique. For the measurements, silicone by condensation of light consistency that was interposed between base and model was used. With a hydraulic press, 50 kg pressure was applied leading the base of the model. The obtained mold was measured in the palate, canine and molar regions with a digital caliper at the following times: immediately after the base polymerization, at 24, 48, 72, 96 hours and one week. The results were submitted to statistical analysis. Result G1 presented maladaptation of 0.43 mm ± 0.10, while G2 obtained 0.39 mm ± 0.11. The lowest maladaptation occurred in the CG. The palate region presented greater maladaptation (0.52 ± 0.07) and the canine region, the lowest (CD = 0.27 mm ± 0.07 and CE = 0.27 ± 0.09); There was no statistically significant difference for storage times. Conclusion G2 presented lower values than G1, with no statistically significant difference. The palate region presented greater maladaptation, followed by molars and canines. The bases continued to maladaptation the model after the immediate polymerization, with no statistically significant difference.
