Sit-to-stand (STS) activity from a chair is an important motion in daily life. Some commercial products assist with STS activity in toilet use. These products control seat orientation by changing three parameters, i.e., seat height, tilt, and shift in a forward-backward direction. The reason for selection of these three parameters for seat orientation control has not been reported. Moreover, there are no reports on the best combination of these parameters. Therefore, in this study, we investigated the relationship between ease of STS activity and seat orientation during STS activity. We found that seat tilting provided good support for STS activity when the seat was in a high position (0.55 m), and shifting the seat forward provided good support for STS activity when the seat was higher than 0.45–0.55 m.

AbstractThis study explored the association between temperament—i.e., positive affect (PA) and negative affect (NA)—and emotion regulation (ER), and what momentary factors influence the selection of rumination or reappraisal during adolescents’ daily life. The type of social situation in which negative events occurred, the self-rated degrees of discomfort, the types of predominant emotions experienced, and the use of reappraisal and rumination were assessed at 24 different times with an ecological momentary assessment approach given to 71 adolescents. PA, NA, and ER style were evaluated using self-reports. Bivariate Pearson correlations analysis revealed that NA and negative ER style correlated positively with the rumination use whereas PA correlated negatively with the rumination use. Negative ER style moderated the relationship between NA and the frequency with which rumination was used. The moderated function of positive ER style could not be tested due to its lack of association with the rumination use. Adolescents selected rumination more often during family-related events and when experiencing depression-like emotions. No interaction effects were shown between negative ER style and the momentary factors related with the type of social situation and the type of prevailing emotion during negative event. No associations between study variables and reappraisal were found. This study provides a better understanding of ER patterns in adolescence.

The present research study was conducted in two public sector universities in Islamabad, Pakistan to explore the relationship between womens education and empowerment. In this research we have looked at the five major dimensions of the womens empowerment in conjunction with education i.e. (1) freedom of movement, (2) economic activism, familial and social affairs (3) freedom from domination and support by the family, (4) decision-making in daily life, and (5) political participation and community engagement. The data was collected from 30 female respondents (15 university teachers and 15 recently passed-out university graduates). The selection of the respondents was made through purposive sampling but with a special inclusion criterion. Based on the research findings, we can suggest that higher levels of education could positively be associated with the higher levels of womens empowerment.

With the growing aridity of the climate on the Don, it became necessary to improve the methodology for conducting the  breeding of spring durum wheat. The main method of obtaining the source material remains intraspecific step hybridization. Crossings were performed between genetically distant forms, differing in origin and required traits and properties. The use of chemical mutagenesis was a productive way to change the heredity of genotypes in terms of drought tolerance. When breeding for productivity, both in dry years of research and in favorable years, the most objective markers were identified — the size of the aerial mass, the mass of grain per plant, spike, and harvest index. The magnitude of the correlation coefficients between the yield per unit area and the elements of its structure is established. It was most closely associated with them in dry years, while in wet years it decreased. Power the correlation of the characteristics of the pair - the grain yield per square meter - the aboveground biomass averaged r = 0.73, and in dry years it was higher (0.91) than in favorable ones (0.61 - 0.70) , between the harvest and the harvest index - r = 0.81 (on average). In dry years, the correlation coefficient increased to 0.92. Research data confirms the greatest importance of the mass of grain from one ear and the plant in the formation of grain yield per unit area in both dry and wet years. In dry years, the correlation coefficient between yield and grain mass per plant was on average r = 0.80; in favorable years, r = 0.69. The relationship between yield and grain mass from the ear was greater — r = 0.84 and r = 0.82, respectively. Consequently, the breeding significance of the aboveground mass and the productivity of the ear, as a criterion for the selection of the crop, especially increases in the dry years. They were basic in the selection.

Background: Combining optimized cognitive (Alzheimer's Disease Assessment Scale- Cognitive subscale, ADAS-Cog) and atrophy markers of Alzheimer's disease for tracking progression in clinical trials may provide greater sensitivity than currently used methods, which have yielded negative results in multiple recent trials. Furthermore, it is critical to clarify the relationship among the subcomponents yielded by cognitive and imaging testing, to address the symptomatic and anatomical variability of Alzheimer's disease. Method: Using latent variable analysis, we thoroughly investigated the relationship between cognitive impairment, as assessed on the ADAS-Cog, and cerebral atrophy. A biomarker was developed for Alzheimer's clinical trials that combines cognitive and atrophy markers. Results: Atrophy within specific brain regions was found to be closely related with impairment in cognitive domains of memory, language, and praxis. The proposed biomarker showed significantly better sensitivity in tracking progression of cognitive impairment than the ADAS-Cog in simulated trials and a real world problem. The biomarker also improved the selection of MCI patients (78.8±4.9% specificity at 80% sensitivity) that will evolve to Alzheimer's disease for clinical trials. Conclusion: The proposed biomarker provides a boost to the efficacy of clinical trials focused in the mild cognitive impairment (MCI) stage by significantly improving the sensitivity to detect treatment effects and improving the selection of MCI patients that will evolve to Alzheimer’s disease.

Aim of review. Interpretation of published evidence on the relationship between the excessive belching syndrome and functional dyspepsia (FD) and their management in patient care.Key points. According to the Rome IV criteria of functional gastrointestinal disorders (FGID), excessive belching in the absence of other dyspeptic symptoms is to be considered a manifestation of the excessive belching syndrome, which can be of gastric or supragastric nature. Combination of high-resolution manometry and impedancemetry allows an accurate diagnosis of belching and selection of optimal treatment strategy. Belching complicated by other symptoms of dyspepsia is to be considered yet another FD symptom according to the Rome IV criteria of FGID. Prokinetics are recommended to relieve belching in such cases.Conclusion. Understanding the relationship between the excessive belching syndrome and FD requires further research.

Epichloë Endophyte

For 30 years, forage ryegrass breeding has known that the germplasm may contain a maternally inherited symbiotic Epichloë endophyte. These endophytes produce a suite of secondary alkaloid compounds, dependent upon strain. Many produce ergot and other alkaloids, which are associated with both insect deterrence and livestock health issues. The levels of alkaloids and other endophyte characteristics are influenced by strain, host germplasm, and environmental conditions. Some strains in the right host germplasm can confer an advantage over biotic and abiotic stressors, thus acting as a maternally inherited desirable ‘trait’. Through seed production, these mutualistic endophytes do not transmit into 100% of the crop seed and are less vigorous than the grass seed itself. This causes stability and longevity issues for seed production and storage should the ‘trait’ be desired in the germplasm. This makes understanding the precise nature of the relationship vitally important to the plant breeder. These Epichloë endophytes cannot be ‘bred’ in the conventional sense, as they are asexual. Instead, the breeder may modulate endophyte characteristics through selection of host germplasm, a sort of breeding by proxy. This article explores, from a forage seed company perspective, the issues that endophyte characteristics and breeding them by proxy have on ryegrass breeding, and outlines the methods used to assess the ‘trait’, and the application of these through the breeding, production, and deployment processes. Finally, this article investigates opportunities for enhancing the utilisation of alkaloid-producing endophytes within pastures, with a focus on balancing alkaloid levels to further enhance pest deterrence and improving livestock outcomes.

ABSTRACTEmbedded structural health monitoring systems are envisioned to be an important component of future transportation systems. One of the key challenges in designing an SHM system is the choice of sensors, and a sensor layout, which can detect unambiguously relevant structural damage. This paper focuses on the relationship between sensors, the materials of which they are made, and their ability to detect structural damage. Sensor selection maps have been produced which plot the capabilities of the full range of available sensor types vs. the key performance metrics (power consumption, resolution, range, sensor size, coverage). This exercise resulted in the identification of piezoceramic Lamb wave transducers as the sensor of choice. Experimental results are presented for the detailed selection of piezoceramic materials to be used as Lamb wave transducers.

AbstractThe camp and the city are both important for understanding the relationship between space and identity in the refugee experience of exile. In the Palestinian example, the camp has emerged as a potent symbol in the narrative of exile although only a third of refugees registered with UNRWA live in camps. Moreover, the city and urban refugees remain missing in most of the scholarship on the Palestinian experience with space, exile, and identity. Furthermore, there is little attention to how refugees understand the concept of the city and camp in their daily life. This article examines how Palestinian urban refugees in the Old City of Damascus conceptualized the relationship between the camp and the city. It illustrates how the concept of the camp remained necessary for the construction of their collective national identity while in Syria. However, the city was essential in the articulation of individual desires and establishing social distinction from other refugees. Thus, during a protracted exile it is in the interstice between the city and the camp, where most urban refugees in the Old City situated themselves, that informed their national belonging and personal aspirations.

Abstract Background and Purpose. The sit-to-stand (STS) movement is a skill that helps determine the functional level of a person. Assessment of the STS movement has been done using quantitative and semiquantitative techniques. The purposes of this study were to identify the determinants of the STS movement and to describe their influence on the performance of the STS movement. Methods. A search was made using MEDLINE (1980–2001) and the Science Citation Index Expanded of the Institute for Scientific Information (1988–2001) using the key words “chair,” “mobility,” “rising,” “sit-to-stand,” and “standing.” Relevant references such as textbooks, presentations, and reports also were included. Of the 160 identified studies, only those in which the determinants of STS movement performance were examined using an experimental setup (n=39) were included in this review. Results. The literature indicates that chair seat height, use of armrests, and foot position have a major influence on the ability to do an STS movement. Using a higher chair seat resulted in lower moments at knee level (up to 60%) and hip level (up to 50%); lowering the chair seat increased the need for momentum generation or repositioning of the feet to lower the needed moments. Using the armrests lowered the moments needed at the hip by 50%, probably without influencing the range of motion of the joints. Repositioning of feet influenced the strategy of the STS movement, enabling lower maximum mean extension moments at the hip (148.8 N·m versus 32.7 N·m when the foot position changed from anterior to posterior). Discussion and Conclusion. The ability to do an STS movement, according to the research reviewed, is strongly influenced by the height of the chair seat, use of armrests, and foot position. More study of the interaction among the different determinants is needed. Failing to account for these variables may lead to erroneous measurements of changes in STS performance.
