Biological determinants of plant and crop productivity of flax (Linum usitatissimum L.)
Tadeusz Zaj？c,Andrzej Oleksy,Agnieszka Klimek-Kopyra,Bogdan Kulig
Acta Agrobotanica , 2012, DOI: 10.5586/aa.2012.016
Abstract: In Poland the cultivation of the fibrous form of flax (Linum usitatissimum L.) is dying out, but the acreage of its oilseed form, linseed, which provides seed (Semen lini) used in therapy and being a source of -linolenic acid, is expanding. Nowadays, linseed is grown in 64 countries of the world, but yield levels in these countries vary greatly. Under European conditions, seed yield of linseed shows high variation, which is evidence of little knowledge of the biology of this plant and the lack of precise cultivation solutions in agricultural technologies used. A major reason is the difficulty in obtaining optimal crop density. A sparse crop results in low above-ground biomass yield, which is translated into insufficient crop yields. The selection of highly productive domestic and foreign varieties can partially increase linseed yield; apart from some domestic varieties, the Canadian cultivar 'Flanders' and the Hungarian cultivar 'Barbara' are positive examples in this respect. There is a possibility of effective selection at early stages of linseed breeding, which bodes well for the prospect of obtaining highly productive varieties with normal or very low -linolenic acid content.
Using the Footfall Sound of Dairy Cows for Detecting Claw Lesions

Abstract: Claw lesions affect the health and well-being of dairy cows and are the third most frequent reason for culling. The most common method to identify cows affected by claw lesions is the assessment of locomotion. However, this requires apart from a trained observer a lot of time. And time is an important limiting factor especially with increasing herd sizes. Thus, regarding the detection of claw lesions, a sensor-assisted, automated system to be implemented on farms should be developed. This system analyzes the footfall sound of cows to distinguish lame from non-lame animals. Using a runway with sensors for recording the footfall sound, we found that cows with non-infectious diseases such as sole ulcers showed a less forceful gait pattern than healthy ones. It is known that particular cows with non-infectious diseases have a greater sensitivity to pain. Therefore the established system is capable of selecting cows that take more cautious steps. This character of abnormal gait pattern is in turn a sign of lameness. Therefore, the automated system as developed in this study is a promising tool for detecting lameness in dairy cows on farms

Journal of Central European Agriculture , 2012, DOI: 10.5513/jcea01/12.4.984
Abstract: The aim of this experiment was to estimate possible associations between GHRL G375A genotypes and some milk performance traits (yields of milk, protein and fat, and protein and fat content). The study included Polish Holstein–Friesian strain Red-and-White cows. The ACRS and PCR-RFLP method was used to identification genotypes. GHRL G375A frequencies were as follow: AA – 0.86, AG- 0.14, and GG – was not found, while allele frequencies were: A – 0.93 and G – 0.07. In this study, no statistically significant correlation between GHRL genotypes and analyzed traits was found, however, a tendency to maintain a relationship of genotypes with milk production traits is shown.

Abstract: Every year our pharmacy programs enroll new students. Some of these students will transition smoothly, but others may not transition optimally. This transition issue can have potentially severe mental health consequences and be caused by a multitude of factors. We need to identify these factors, be able to identify at-risk students, and have programs in place to help better support our students’ mental health

A Physical Insight into the Origin of the Corrections to the Magnetic Moment of Free and Bound Electron  [PDF]

Journal of Modern Physics (JMP) , 2020, DOI: 10.4236/jmp.2020.119081
Abstract: The main goal of the present work is a unitary approach of the physical origin of the corrections to the magnetic moment of free and bound electron. Based on this approach, estimations of lowest order corrections were easily obtained. In the non-relativistic limit, the Dirac electron appears as a distribution of charge and current extended over a region of linear dimension of the order of Compton wavelength, which generates its magnetic moment. The e.m. mass (self-energy) of electron outside this region does not participate to this internal dynamics, and consequently does not contribute to the mass term in the formula of the magnetic moment. This is the physical origin of the small increase of the magnetic moment of free electron compared to the value given by Dirac equation. We give arguments that this physical interpretation is self-consistent with the QED approach. The bound electron being localized, it has kinetic energy which means a mass increase from a relativistic point of view, which determines a magnetic moment decrease (relativistic Breit correction). On the other hand, the e.m. mass of electron decreases at the formation of the bound state due to coulomb interaction with the nucleus. We estimated this e.m. mass decrease of bound electron only in its internal dynamics region, and from it the corresponding increase of the magnetic moment (QED correction). The corrections to the mass value are at the origin of the lowest order corrections to the magnetic moment of free and bound electron.
Cracking the Snake Detection Theory: The Subcortical Visual Pathway as a Major Player in Cultural Transformations  [PDF]

Abstract: According to the proposed hypothesis, graphic characters trigger the subcortical visual route. The reaction discussed is very weak. Yet, its very existence has an unusual importance: characters and (occluded) venomous snakeskin patterns reveal themselves as conflatable. Furthermore, following tractogra- phic research, a functional segregation of the subcortical pathway is to be presupposed. Thus, there can’t be a later dissociation of two stimuli previously associated. The outcomes of lecture will gradually appear probabilistically (much) more peaceful than encountering a venomous snake, though, and thus a continuous lessening of the reaction is expectable. Here, on one hand, it is relevant that the subcortical visual pathway goes to the amygdala. The reactions we describe tap into goal-oriented processes, and they will do that unfettered. On the other hand, in the case of characters, since the beginning, fear has been converted into appetition to a great degree. This process should be fostered in the presence of light. In this way, luminosity might become a conditioned stimulus for attraction. In this case, a Pavlovian addiction for light will foster, yet also—from the point of view of reward feeling—counterbalance the lessening of the stimulation elicited by characters. The addiction we refer to is one towards light accompanied by graphic signs. Yet, as opposed to the case of the luminous medium, the attention captured by the later ones taken for themselves is continuously reduced.
A Universal Binding Mechanism in Molecular Covalent Bonding and Nucleon-Nucleon Interaction  [PDF]

Journal of Modern Physics (JMP) , 2021, DOI: 10.4236/jmp.2021.129076
Abstract: In the hydrogen molecular ion, the kinetic energy lowering of the electron is associated with its delocalization due to electron exchange between the two protons of the molecule. This decrease in the kinetic energy of the exchanged electron in the hydrogen molecular ion and the decrease in the dynamical mass of the two exchanged pions in the nucleon-nucleon interaction are at the origin of the attraction mechanism in the molecular covalent bonding and in the nuclear interaction. Based on this unitary approach of the attraction mechanism, the formulas of molecular potential and central nucleon-nucleon potential were derived. The decrease in the mass of the exchanged pions in the nucleon-nucleon bound state, actually means the decrease in the mass of the nucleons. This nucleon mass decrease could be a manifestation of the partial chiral symmetry restoration in nuclear matter.

Abstract: We developed a randomized, placebo-controlled clinical trial designed to test the hypotheses that hands-on treatment procedures administered to individuals following ankle sprains during the post-acute injury period can improve short-, intermediate-, and long-term disablement, as well as reduce the risk for re-injury.This study is designed to measure the clinical effects of hands-on passive stretching treatment procedures directed to the talocrural joint that vary in treatment speed during the post-acute injury period, compared to hands-on placebo control intervention.http://www.clinicaltrials.gov identifier NCT00888498.Ankle sprains are the most common injury to the ankle joint, accounting for up to 2 million injuries per year [1]. Annual incidence is estimated at 52.7 per 10,000 individuals [2]. Ankle injuries are very common in younger and active individuals, second only to the knee in the annual incidence of lower extremity sports-related injuries [3,4]. Among high school athletes in the United States, sprains account for 50% of all lower extremity injuries [5] with the ankle joint most commonly affected [5-7]. In one sample of individuals with non-athletic mechanisms of injury, sprains accounted for over 40% of reported injuries with the ankle joint also most commonly affected [8]. Certain sports and work activities may result in an even higher incidence and risk for injury [9-15]. Ankle sprains are clinically significant because they result in a substantial number of missed work days [8] and participation in sports activity [3,5], as well as potential early arthritic changes in the talocrural joint [16].Lateral ankle and midfoot injuries account for 80-85% of all sprains [17,18]. The most common mechanism of injury for ankle sprains involves plantarflexion and inversion of the ankle and foot, which places excessive load on the anterior talofibular ligament. With failure of this ligament, secondary restrain to inversion occurs by way of the calcaneofibular and

Abstract: Background Ulcerative colitis (UC) and Crohn’s disease (CD) belong to inflammatory bowel disease (IBD). The etiology of IBD is still unknown. Therapy remains empiric or is used for the relief of specific symptoms. The erbB-1 oncogene coding epidermal growth factor receptor (EGFR) is typed as a prognostic marker in several benign and malignant tissues. The aim of our study was to examine the erbB-1 expression in experimental surgically performed model of IBD in rats and to find out if there is any correlation between severity of the intestinal inflammation and altered level of erbB-1 expression. After inducing an experimental colitis samples were taken from different parts of the intestine in all studied groups of rats for histopathology. ErbB-1 mRNA expression was estimated by RT-PCR. PCR products were separated on a 1,5% TBE-agarose gel and visualized with ethidium bromide. The integrated optical density (IOD) of electrophoretically separated amplification products was measured using a video densitometer and Gel-Pro 3.0 software. Nonparametrical statistical test has been used throughout in analyzing the results. Relative erbB-1 expression was determined by comparing to cyclophiline expression. Results Microscopic changes were similar to those observed in IBD. ErbB-1 expression was significantly higher in inflamed tissues of the bowel ( P=0.04 for the transverse colon and P=0.027 for the cecum). Significantly higher erbB-1 expression in inflamed tissues of the bowel suggests that EGFR overexpression may play a role in the pathogenesis of IBD. Overexpression of erbB-1 correlates with the severity of inflammation in bowel tissues.
