Post stroke psychiatric syndrome: a clinical study

Background: Various psychiatric symptoms are seen after strokes which are usually deserted due to poor familiarity about it, hence better knowledge and understanding of various post stroke psychiatric manifestations may help in early identification and management of it. The aim of present research is to study the demographic and clinical profile of various post stroke psychiatric manifestations. Methods: The study was conducted on ninety patients developing psychiatric symptoms after stroke. Detailed sociodemographic characteristics, clinical profile along with psychiatric assessment were recorded in proforma specially designed for the study. Results: Bulk of this poststroke psychiatric subjects (45%) was in the age range of 61-80 years of which male and female were 29% and 16% respectively. Most of patients (90%) were residing at rural areas. 47.8 % patients were belonging to lower middle socio-economic status. Majority of subjects (42.8%) were unemployed followed by farmer and skilled worker (20% each), and most of the patients were right handed (97.8%). On clinical parameters maximum subjects (52.2) developed post stroke major depression followed by depression mixed with anxiety (16.6%). Rest of patients suffered from organic anxiety disorder (8.8%), vascular dementia (10%), amnestic syndrome (5.5%), post stroke psychosis (3.3%), organic manic disorder (2.2%), pathological laughter and crying (1.1%). Conclusions: Huge number of patients (52.9%) developed psychiatric problems of diverse nature among patients with stroke syndrome. depression was most common post stroke psychiatric manifestation, followed by mixed anxiety with depression. Generally the post stroke psychiatric manifestations are unrecognized and untreated, which has adverse impact on process of stroke rehabilitation. Thus a detailed psychiatric evaluation is mandatory in all patients of stroke syndrome to rule out psychiatric illness.

High‐performance vacuum‐processed metal oxide thin‐film transistors: A review of recent developments

Since 2010, vacuum‐processed oxide semiconductors have greatly improved with the publication of more than 1,300 related papers. Although the number of researches on oxide semiconductors has continued to increase year by year, the average field‐effect mobility of oxide semiconductor thin‐film transistors (TFTs) has not shown significant improvement; from 2010 to 2018; the average field‐effect mobility of vacuum‐processed n‐type oxide TFTs is around 20 cm2/Vs. To investigate the obstacles for performance improvements, the latest progress and researches on vacuum‐processed oxide semiconductor TFTs for high performance over the past decade are highlighted, along with the pros and cons of each technology. Finally, complementary metal oxide semiconductor (CMOS) logic circuits composed of both n‐ and p‐type oxide semiconductor TFTs are introduced, and future prospects for this state‐of‐the‐art research on the oxide semiconductors are presented.
Local recruitment of great and blue tits (Parus major, P. caeruleus) in relation to study plot size and degree of isolation

Few studies are available that analyse variation in dispersal rates between populations. Here we present data on the degree of local recruitment (LR) of great and blue tits (Parus major, P. caeruleus) in a large number of nest-box plots in northern Belgium that vary in size, degree of isolation and population density, These plots have been studied for varying lengths of time over the past 40 yr. As expected, I.R was higher among male than female birds, and this difference was most pronounced in blue tits. Regardless of species and sex, more local recruits were found in larger plots but also in plots with a higher population density, Thus, LR increased with population size (number of pairs) but levelled off in the largest populations at ca 50% for male birds, LR was higher in forest fragments compared to plots inside continuous forest suggesting that fragmentation reduces exchange among local populations. However. LR was not related to the degree of isolation of individual fragments. We also found a weak but significant increase in LR with productivity (number of nestlings) of plots, but no relationship with other demographic variables.
Selecting spare parts suitable for additive manufacturing: a design science approach

Abstract Additive manufacturing (AM) help in delivering spare parts within short lead times and thus avoid maintaining huge inventories. Companies exploring opportunities to produce spare parts using AM face challenges in identifying suitable spare parts. Moreover, a single method may not be applicable for all companies. An idiosyncratic approach needs to be adopted by considering the characteristics of parts in the portfolio. This study follows a design science approach to address an evident research gap by developing a process to identify spare parts suitable for AM. The case data were analysed using multi-criteria decision-making and cluster analysis techniques. The research contributes by developing and demonstrating a methodology to identify spare parts suitable for AM from a portfolio of a large number of spare parts, where adequate discrimination was not obtained by ranking all parts together. The study develops generic guidelines for spare parts selection for AM and outline the generalizability of the proposed methodology beyond the domain of part selection for AM.
Avaliação das carcaças de novilhos F1 Angus-Nelore em pastagens de Brachiaria decumbens submetidos a diferentes regimes alimentares

This trial was conducted at National Beef Cattle Research Center of Brazilian Agricultural Research Corporation (Embrapa Beef Cattle). Forty five F1 Aberdeen Angus-Nellore steers were used to evaluate the effects of different dry seasons feeding schemes on carcass characteristics. The treatments were: control, without supplementation (S/S); supplementation in 2nd dry period (S2S); supplementation in 1st dry period (S1S); supplementation in 1st and 2nd dry periods (S12S) and supplementation in 1st dry period and confinament in 2nd one (S1C2). Animals were slaughtered at 460-480 kg of live weight and the treatments effects were evaluated by least square means. Steers with higher nutritional levels in 2nd dry season (S1C2; S2S; S12S) showed more dressing percentage and higher hot and cold carcass weights than those supplemented only in 1st dry period or non supplemented. Animals supplemented only in 1st dry season showed similar carcasses than non supplemented. It was concluded that increasing the 2nd dry season nutritional level is primary to expand the dressing percentage. Supplementation in 1st dry period solitarily does not affect dressing percentage neither carcass quality.
Early Holocene Indian summer monsoon and its impact on vegetation in the Central Himalaya: Insight from δD and δ13C values of leaf wax lipid

Increase in rainfall during the early Holocene has been reported from different regions of Indian subcontinent, although the magnitude shows spatial variability with lower change in higher rainfall regions and vice versa. While the early-Holocene rainfall records are available from lowland areas of the Indian sub-continent, the record is poorly documented from the high-altitude Central Himalayan region where orography plays an important role in the spatial variability in the rainfall pattern. For the first time, δDC29, δ13CC29 values of alkane and δ13C values of organic matter from a relict lake of Benital area in the Central Himalaya have been used to reconstruct monsoonal rainfall and contemporary vegetation for last 10.5 ka with an emphasis on the early Holocene. The δDC29 values suggest that the early Holocene was characterized by a wet phase at ca. 9 ka with 25% higher rainfall compared to present while the middle-late-Holocene was relatively arid. The estimated increase in monsoonal rainfall for the early Holocene is the highest compared to the previous report from elsewhere. The magnitude of early-Holocene rainfall estimated in this study suggests that in addition to erosion of the bed-rocks at the head-water region, increased stream power reworked the older floodplain and resulted in 2.3 times higher sediment discharged into the Ganges-Brahmaputra (GB) delta compared to the present discharge. The δ13CC29 values of the lake sediments suggest a transition from woody to non-woody plant assemblages occurred at 7 ka. The poor correlation between δDC29 and δ13CC29 values suggests at higher rainfall, the δ13CC29 values of catchment vegetation were less responsive.
A measurement method of knee joint space width by ultrasound: a large multicenter study.

Background Although plain radiology is the primary method for assessing joint space width (JSW), it has poor sensitivity to change over time in regards to determining longitudinal progression. We, therefore, developed a new ultrasound (US) measurement method of knee JSW and aimed to provide a monitoring method for the change of JSW in the future. Methods A multicenter study was promoted by the Professional Committee of Musculoskeletal Ultrasound, the Ultrasound Society, and the Chinese Medical Doctor Association. US study of knee specimens determined the landmarks for ultrasonic measurement of knee JSW. The US of 1,272 participants from 27 centers was performed to discuss the feasibility and possible influencing factors of knee JSW. The landmarks for US measurement of knee JS, the inflection point of medial femoral epicondyle and the proximal end of the tibia, were determined. Results The mean knee JSW1 (medial knee JSW) was 8.57±1.95 mm in females and 9.52±2.31 mm in males. The mean knee JSW2 (the near medial knee JSW) was 9.07±2.24 mm in females and 10.17±2.35 mm in males. The JSW values of males were significantly higher than those of females, with a statistical difference. JSW values were negatively correlated with age and body mass index (BMI) to different degrees and positively correlated with height. Conclusions The novel US measurement method can be used to measure knee JSW.
Nitrate-dominated PM2.5 and elevation of particle pH observed in urban Beijing during the winter of 2017

Abstract. The Chinese government has exerted strict emission controls to mitigate air pollution since 2013, which has resulted in significant decreases in the concentrations of air pollutants such as SO2. Strict pollution control actions also reduced the average PM2.5 concentration to the low level of 39.7 µg m−3 in urban Beijing during the winter of 2017. To investigate the impact of such changes on the physiochemical properties of atmospheric aerosols in China, we conducted a comprehensive observation focusing on PM2.5 in Beijing during the winter of 2017. Compared with the historical record (2014–2017), SO2 decreased to the low level of 3.2 ppbv in the winter of 2017, but the NO2 level was still high (21.4 ppbv in the winter of 2017). Accordingly, the contribution of nitrate (23.0 µg m−3) to PM2.5 far exceeded that of sulfate (13.1 µg m−3) during the pollution episodes, resulting in a significant increase in the nitrate-to-sulfate molar ratio. The thermodynamic model (ISORROPIA II) calculation results showed that during the PM2.5 pollution episodes particle pH increased from 4.4 (moderate acidic) to 5.4 (more neutralized) when the molar ratio of nitrate to sulfate increased from 1 to 5, indicating that aerosols were more neutralized as the nitrate content elevated. Controlled variable tests showed that the pH elevation should be attributed to nitrate fraction increase other than crustal ion and ammonia concentration increases. Based on the results of sensitivity tests, future prediction for the particle acidity change was discussed. We found that nitrate-rich particles in Beijing at low and moderate humid conditions (RH: 20 %–50 %) can absorb twice the amount of water that sulfate-rich particles can, and the nitrate and ammonia with higher levels have synergetic effects, rapidly elevating particle pH to merely neutral (above 5.6). As moderate haze events might occur more frequently under abundant ammonia and nitrate-dominated PM2.5 conditions, the major chemical processes during haze events and the control target should be re-evaluated to obtain the most effective control strategy.
Effects of a Physical Treatment Applied Immediately after Chilling on the Structure of Muscle Fiber and the Texture of Cooked Broiler Breast Meat

Abstract Broiler processors continue to look for ways to decrease aging time prior to muscle removal from carcasses and maintain tender breast meat. The ultimate goal is to remove breast muscles from carcasses after chilling without additional aging. A physical treatment was applied to deboned broiler breasts immediately after chilling, and the effect on fiber integrity and texture were determined. The flattened breast fillets were held at 35°F for 2, 6, 12, or 24 hours prior to cooking in order to determine the effects of holding time after flattening. A control group of breasts (non-flattened) was compared to the treated breasts. The physical treatment resulted in a reduction in height and fiber damage to the breast muscles, and a reduction in shear values (more tender meat). Holding the treated muscles for longer times prior to cooking did not result in a significant reduction in shear values.
An acoustic emission-based approach to structural health monitoring of pre-stressed concrete railway sleepers

Railway sleepers represent an essential element of the track; indeed, their structural integrity is closely related to important technical and safety issues. Today, periodical visual inspections are the only method applied to check the status of sleepers but are limited to visible surfaces, whereas the early detection of in-service cracks in the whole volume of sleepers would provide great advantages in terms of maintenance and management. The aim of the paper is to propose an acoustic emission (AE)-based structural health monitoring (SHM) approach that is able to detect the initiation and propagation of cracks in in-service pre-stressed concrete sleepers. The investigation is carried out in the laboratory, comparing the results obtained by acoustic emission monitoring and digital image correlation when subjecting pre-stressed concrete sleepers, taken from production, to both static and cyclic loads. The main points dealt with in the paper include the sensitivity of acoustic emission to detect damage development and the signal processing approach needed for defining effective damage indexes. Given the encouraging results, the paper is the first step in developing an affordable monitoring system, to be embedded into sleepers, that is able to be part of a complete track monitoring system.
Internasionalisasi dan Reformasi Perguruan Tinggi: Studi Kasus Pada Lembaga Pendidikan Tinggi Muhammadiyah

Educational institutions, especially tertiary education, are designed to spearhead the development of the quality of human resources. The strategic role needed by tertiary institutions makes intensive attention to improving its quality. This article discusses how to analyze Muhammadiyah Universities (PTM) to transform institutions from national to international scale. This article is carried out by discussing case studies from PTM. Data collection was carried out through several meetings gathering desk research, interviews, and document studies. Analyzes were performed by pattern matching, cross-case synthesis, and explanation building. The results show several aspects of PTM internationalization. Good governance in achieving the objectives of internationalization must be carried out in the form of a vision, mission, goals, quality policy and strategic plan. An internationalization process that demands specialized institutions that require international cooperation and activities. To support internationalization, the development of HR and decision-making systems that are fast and not rigid are important to consider.
Ambient Backscatter Communication Networks

Energy harvesting is a prominent solution to enable self-sustainable operations of wireless communication networks, thus playing a critical role in green communications [1]. By deriving energy from external sources, energy harvesting has been widely adopted in low-power communication devices and sensors. Depending on energy sources, there are several types of energy harvesting techniques suitable for different applications as shown in Table 1.1.
Motivations for (non‐)compliance with conservation rules by small‐scale resource users

Understanding compliance with conservation rules is key for biodiversity conservation. Here, we assess compliance and its underlying motivations in a small‐scale fishery in Chile. We adapt a framework originally developed for forestry to unpack compliance motivations at within‐individual and between‐individuals levels while accounting for contextual factors. We find that 92–100% fishers comply with temporal or gear rules, while only 3% comply with the quota limit. Legitimacy‐based motivations are more important in explaining why individual fishers comply with temporal/gear rules than they are for compliance with the quota. At the between‐individuals level, we find that normative motivations are significantly related to the degree of non‐compliance with the quota. Contextual factors such as quota levels are key in explaining broader non‐compliance patterns. Our results suggest that considering compliance at appropriate analytical levels is necessary to unpack motivations, guide local and national natural resource management policies, and move toward a better theory of compliance.
Skeletons in the cupboard? Quantifying bird predation on Atlantic salmon: atlas vertebra:fish length equations revisited

Throughout Europe there is considerable concern about the potential impact of sawbill ducks Mergus spp. and great cormorant Phalacrocorax carbo on catches of commercial fish (reviews by Marquiss & Carss, 1994; Russell et al., 1996). A prerequisite to estimating impact is to quantify the consumption of commercially important fish by birds. This requires site-specific data on (1) bird numbers, (2) their daily food intake and (3) diet. Considerable effort has been directed at quantifying (2) and (3) and exploring the biases associated with different methods (see Carss et al., 1997 for review).
Surface Conduction Model for Fractal Porous Media

The electrical conductivity of natural water‐saturated porous materials has two contributions, one associated with conduction in the pore network and a second one associated with the electrical double layer coating the surface of the mineral grains, and called surface conductivity. We model the effect of material texture on surface conductivity based on fractal theory. We demonstrate that surface conductivity obeys a power‐law dependence (that we called surface Archie's law) on the specific surface area. The power exponent is theoretically related to the porosity exponent entering Archie's law and to the fractal dimension of the pore network. A permeability model is derived by combining the new surface Archie's law and the Kozeny‐Carman model. We show that our model is consistent with both numerical finite element simulations on synthetic porous media and experimental data.
Analysis of Upper-Limb and Trunk Kinematic Variability: Accuracy and Reliability of an RGB-D Sensor

In the field of motion analysis, the gold standard devices are marker-based tracking systems. Despite being very accurate, their cost, stringent working environments, and long preparation time make them unsuitable for small clinics as well as for other scenarios such as industrial application. Since human-centered approaches have been promoted even outside clinical environments, the need for easy-to-use solutions to track human motion is topical. In this context, cost-effective devices, such as RGB-Depth (RBG-D) cameras have been proposed, aiming at a user-centered evaluation in rehabilitation or of workers in industry environment. In this paper, we aimed at comparing marker-based systems and RGB-D cameras for tracking human motion. We used a Vicon system (Vicon Motion Systems, Oxford, UK) as a gold standard for the analysis of accuracy and reliability of the Kinect V2 (Microsoft, Redmond, WA, USA) in a variety of gestures in the upper limb workspace—targeting rehabilitation and working applications. The comparison was performed on a group of 15 adult healthy subjects. Each subject had to perform two types of upper-limb movements (point-to-point and exploration) in three workspace sectors (central, right, and left) that might be explored in rehabilitation and industrial working scenarios. The protocol was conceived to test a wide range of the field of view of the RGB-D device. Our results, detailed in the paper, suggest that RGB-D sensors are adequate to track the upper limb for biomechanical assessments, even though relevant limitations can be found in the assessment and reliability of some specific degrees of freedom and gestures with respect to marker-based systems.
Biostatistical Studies of Western-european Allogamous Populations of the Epipactis-helleborine (l) Crantz Species Group (orchidaceae)

Multivariate methods using morphological characteristics were applied to the study of 23 western European allogamous Epipactis populations belonging to five taxa in the E. helleborine group and two taxa in the E. atrorubens group. The study concentrated on four recently described, not yet widely accepted, taxonomic entities of the former group and on the identification of discriminant characters. Several vegetative and floral differences allow proper discrimination of E. helleborine s. str. , E. distans, E. neerlandica, and a subgroup composed of E. tremolsii and E. lusitanica. A more detailed analysis was needed for the latter two, for which the differences are chiefly vegetative. The five taxa also possess distinctive ecological characteristics and, considering the respective geographical ranges and sympatries, can be regarded as independent species.
