Wheel Alignment detection using Raspberry Pi - The development of automobile technology is evolving and the influence of automobile stability to travel safely is increasing. A modern person usually has wheel alignments both for front and rear wheels. For that detection is needed, here comes the role of our device. Here 3 elements are important Camber, Castor and Toe which needs to be looked after for alignment. All four tires should be in straight line. A further thing which matters is Knuckle, Bearing and Jumper. By rash driving alignment gets disturbed which affects tire wear and tear. Here, user can get affected by frequent tire replacement which leads to cost on maintenance. Here, every tire calculations are different and they should be precise. For maintaining that using sensors calculations are maintained which can be done using Raspberry Pi and Python as implementation language.

The American flamingo is a useful model for the development of successful semen cryopreservation procedures to be applied to threatened related species from the family Phoenicopteridae, and to permit genetic material banking. Current study sought to develop effective sperm cryopreservation protocols through examining the influences of two permeating cryoprotectants and the seminal plasma removal. During two consecutive years (April), semen samples were collected and frozen from American flamingos. In the first year, the effect of two permeating cryoprotectants, DMA (dimethylacetamide) (6%) or Me2SO (dimethylsulphoxide) (8%), on frozen–thawed sperm variables were compared in 21 males. No differences were seen between DMA and Me2SO for sperm motility, sperm viability, and DNA fragmentation after thawing. In the second year, the role of seminal plasma on sperm cryoresistance was investigated in 31 flamingos. Sperm samples were cryopreserved with and without seminal plasma, using Me2SO (8%) as a cryoprotectant. The results showed that samples with seminal plasma had higher values than samples without seminal plasma for the following sperm variables: Straight line velocity (22.40 µm/s vs. 16.64 µm/s), wobble (75.83% vs. 69.40%), (p < 0.05), linearity (62.73% vs. 52.01%) and straightness (82.38% vs. 73.79%) (p < 0.01); but acrosome integrity was lower (55.56% vs. 66.88%) (p < 0.05). The cryoresistance ratio (CR) was greater in samples frozen with seminal plasma than without seminal plasma for CR-progressive motility (138.72 vs. 54.59), CR-curvilinear velocity (105.98 vs. 89.32), CR-straight line velocity (152.77 vs. 112.58), CR-average path velocity (122.48 vs. 98.12), CR-wobble (111.75 vs. 102.04) (p < 0.05), CR-linearity (139.41 vs. 113.18), and CR-straightness (124.02 vs. 109.97) (p < 0.01). This research demonstrated that there were not differences between Me2SO and DMA to successful freezing sperm of flamingos; seminal plasma removal did not provide a benefit for sperm cryopreservation.

Nowadays Russian manufacturers of metal-cutting tools for machine-building industry do not offer structures of prefabricated cutting hobs with retrofittable carbide blades for processing of tooth wheels, though usage of retrofittable carbide blades allows to increase significantly working capacity and productivity of the processing. As of today creation of an assembly cutting tool for processing of tooth wheels with the retrofittable carbide blades is a big step forward for machine-building industry. A high quality tool allows warranting for a new equipment and making work of operators more productive. This paper offers a new technical solution providing increase of efficiency of processing by assembly tools with the retrofittable carbide blades made of a hard alloy. Due to usage of progressive cutting patterns division of a margin for straight-line segments and curved sections is performed. This division has a positive impact on cutting hard-alloy inserts and also reduces their wear and tear.

A controlled heterogeneous collection of identical items is presented. According to their level of wear and tear, they are divided into a finite number of classes and the partition of the collection is allowed to change over time. A suitable exchangeability assumption is made to preserve the property that the items be identical. The role of the occupation numbers is investigated and a filtering problem is set up, where the observation is the cardinality of a particular class. A control on the dynamics of the items is introduced, and the existence of an optimal control is proved. A discrete-time approximation for the separated problem, which is a finite-dimensional one, is performed. As a consequence, an approximation for the value function is given.

Osteoarthritis (OA) is a degenerative disease that affects various tissues surrounding joints such as articular cartilage, subchondral bone, synovial membrane, and ligaments. No therapy is currently available to completely prevent the initiation or progression of the disease partly due to poor understanding of the mechanisms of the disease pathology. Cartilage is the main tissue afflicted by OA, and chondrocytes, the sole cellular component in the tissue, actively participate in the degeneration process. Multiple factors affect the development and progression of OA including inflammation that is sustained during the progression of the disease and alteration in biomechanical conditions due to wear and tear or trauma in cartilage. During the progression of OA, extracellular matrix (ECM) of cartilage is actively remodeled by chondrocytes under inflammatory conditions. This alteration of ECM, in turn, changes the biomechanical environment of chondrocytes, which further drives the progression of the disease in the presence of inflammation. The changes in ECM composition and structure also prevent participation of mesenchymal stem cells in the repair process by inhibiting their chondrogenic differentiation. This review focuses on how inflammation-induced ECM remodeling disturbs cellular activities to prevent self-regeneration of cartilage in the pathology of OA.

Adaptive Processes

Glucocorticoids (GCs) are the end products of the hypothalamo–pituitary–adrenocortical axis (HPA) and, via activation of the ubiquitously expressed GC receptor, influence numerous physiological processes. GCs are also involved in the regulation of basal homeostasis as well as mediating adaptive responses to stress that act to restore homeostasis. This article discusses the various factors that are important in regulating plasma and intracellular GC concentrations and describes the genomic and non-genomic mechanisms used by GCs to influence cellular processes. We describe the concept of allostatic overload associated with chronic HPA activation and the subsequent development of tissue dysfunction and disease. While allostasis is associated with acute stress and a restoration of homeostasis, chronic stress is likely to induce allostatic overload owing to the sustained activation of adaptive processes. Increased wear and tear in GC-sensitive tissues can eventually lead to tissue dysfunction and disease. Chronic elevations in GCs can also induce dysfunction or disease associated with decreased tissue function owing to the prolonged inhibitory effects of GCs or the redistribution of metabolic resource away from physiological systems not involved in restoring homeostasis. Numerous endocrine-related disorders are associated with aberrant GC levels and in terms of pathophysiology may be linked with chronic tissue-specific alterations in GC actions.

Compass System

Recent research has focused on the different types of compass cues available to ball-rolling beetles for orientation, but little is known about the relative precision of each of these cues and how they interact. In this study, we find that the absolute orientation error of the celestial compass of the day-active dung beetle Scarabaeus lamarcki doubles from 16° at solar elevations below 60° to an error of 29° at solar elevations above 75°. As ball-rolling dung beetles rely solely on celestial compass cues for their orientation, these insects experience a large decrease in orientation precision towards the middle of the day. We also find that in the compass system of dung beetles, the solar cues and the skylight cues are used together and share the control of orientation behaviour. Finally, we demonstrate that the relative influence of the azimuthal position of the sun for straight-line orientation decreases as the sun draws closer to the horizon. In conclusion, ball-rolling dung beetles possess a dynamic celestial compass system in which the orientation precision and the relative influence of the solar compass cues change over the course of the day.

Point Of Departure

This article takes its point of departure in a collection of inventories, presented to Bishop Bror Brorson on his visitation journeys in the diocese of Aalborg, Northern Jutland, in the 1750s. The inventories reveal considerable variations: the majority of schools had 3 to 30 books registered, some schools had between 30 and 60 books regisitered, while a minority of schools had no books at all. However, these books were only the tip of the iceberg. By analysing the school decree of 1739 as well as information in the inventories themselves, it can be demonstrated, how parents were responsible for acquiring the necessary teaching materials themselves. The books registered were first of all free copies for poor children, and some of these books were not even listed, as they had been given away to individual children.The inventories bear witness to a high degree of continuity concerning the schoolbooks used for elementary teaching: ABCs, catechisms, gospel books, expositions of the catechism. But it can also be documented that the government had succeeded in introducing Erik Pontoppidan’s new Pietistic exposition of the catechism from 1737 into all village schools. In contrast, there were no central regulations that dealt with teaching materials for writing and mathematics.Instruction in these subjects was a local matter. Moreover, the inventories reveal a number of book donations, especially from Pietistic pastors, and in some cases unique information about the bindings, as well as the wear and tear of schoolbooks can be found. Thus the inventories provide an intriguing window into everyday teaching practices and the role of school books in 18th century village schools.
