Effect of Greenhouse Cladding Materials and Thermal Screen Configuration on Heating Energy and Strawberry (Fragaria ananassa var. “Seolhyang”) Yield in Winter

Strawberry cultivation depends on environmental factors, making its cultivation in the greenhouse a challenge in the winter. This study investigated the most appropriate greenhouse cladding material and thermal screen configuration for strawberry production in the winter by considering greenhouse air temperature, relative humidity (RH, vapor pressure deficit (VPD, and solar radiation (SR). Two gothic greenhouses with different cladding materials and thermal screen configurations, namely, the single-layer greenhouse and double-layer greenhouse, were used for strawberry cultivation. The greenhouse microclimate was controlled by natural ventilation aided with circulating fans and boilers. Strawberries were planted on 5 greenhouse benches, 660 stands per greenhouse. Daily environmental parameters were recorded and processed into daytime and nighttime. The impacts of cladding material-thermal screen configurations on temperature, RH, VPD, and SR, and the subsequent effect on strawberry yield in both greenhouse systems, were evaluated. Comparing the environmental parameters recorded in the single-layer and double-layer greenhouse showed that VPD and SR were significantly different in the daytime, whereas RH and VPD were significantly different in the nighttime. The post hoc test further showed that RH, VPD, and SR in both greenhouses were significantly different. The significant difference in RH and VPD can be attributed to the inner layer of polyethene in the double-layer greenhouse, which sealed up the pores of the thermal screen, resulting in humidity buildup, causing a lower VPD than in the single-layer greenhouse. The single-layer greenhouse yield was 14% greater than the double-layer greenhouse yield and can be attributed to the higher daytime VPD and lower RH achieved in the single-layer greenhouse at night. The study established that though the single-layer greenhouse system was cost-effective regarding construction, the operating cost of the single-layer greenhouse was higher than that of the double-layer greenhouse.
Butterflies (Lepidoptera: Papilionoidea) of the Restinga de Cabedelo National Forest, Paraíba State, Brazil

Restinga forests are plant formations that occur on plains of quaternary sandy deposits along the Brazilian coast. Despite historical reduction of the Restinga forests, little effort has been made to know the butterfly fauna of these areas. This paper is an important contribution to the butterfly’s knowledge, being the second inventory in the Restinga forest of northeastern Brazil. The survey was conducted in the Restinga de Cabedelo National Forest (FLONA de Cabedelo, following the Portuguese abbreviation) and aimed to provide preliminary information on the butterflies richness in this region. A total of 89 butterfly species and 1,503 individuals were recorded at FLONA de Cabedelo. Hesperiidae was the richest family (34 species), followed by Nymphalidae (33) Pieridae (eight), Lycaenidae (seven), Riodinidae (five), and Papilionidae (two). In general, the butterfly fauna of the FLONA de Cabedelo is dominated by species widely distributed and commonly found in open or forested areas in Brazil. Five species are new records in Paraíba state: Calydna sturnula (Geyer), Theope foliorum (Bates), Cogia hassan (Butler), Vehilius inca (Scudder), and Chiothion asychis (Stoll). We suggest carrying out monthly samplings which will certainly increase the list of species herein presented.

1/f noise, hydrogen transport, and latent interface-trap buildup in irradiated MOS devices

A large, delayed increase is observed in the postirradiation 1/f noise of Oki pMOS transistors prior to the onset of latent interface-trap buildup. Both effects are evidently due to similar thermally activated processes involving hydrogen. The increased noise through irradiation and anneal is found to be caused not only by the generation of defects at or near the Si/SiO/sub 2/ interface, but also by an apparent transition from buried to surface channel conduction. This is evidently triggered by the passivation of dopants in the Si by hydrogen transport during irradiation and anneal. Switched bias annealing confirms many of these effects are reversible. Three types of hydrogen transport are identified in MOS oxides: dispersive transport leading to "two-stage" interface-trap buildup, retarded transport leading to latent interface-trap buildup, and blockaded transport leading to proton confinement in SiO/sub 2/. The nature of the transport appears to correlate with O vacancy density and the temperature at which hydrogen is incorporated into the SiO/sub 2/. Implications are discussed for enhanced bipolar low dose rate response, the sensitivity of pMOS dosimeters, and protonic nonvolatile memory elements.
A particular example of phase unwrapping using noisy experimental data

Obtaining a smooth continuous function of phase from a distorted, sampled set of phase measurements is addressed. Provided the smooth continuous function can be written as a power series, all the important coefficients can be derived from phase difference measurments which have proved to be less affected by phase noise than the phase measured directly. This simple technique is shown to have advantages in some experimental configurations.
A Review of First-Year Student Stress and Social Support

The present paper reviews empirical literature on stress and social support relative to first-year post-secondary students, published between 1996 and 2020. Empirical studies included in the literature search focused on stress, coping, and social support specifically among first-year undergraduate students while studying in countries adopting North American higher education models comparable to the United States and Canada. This review examines contextual and psychological antecedents and correlates of stress, as well as associated demographic and achievement variables. Furthermore, this review extends to studies on social support categorized by source (peers, family, faculty, institution, and multiple sources of support). A synthesis and critique of the literature explores the themes in the empirical research presented, as well as considerations for future research.

Analysis of port‐wine birthmark vascular characteristics by location: Utility of optical coherence tomography mapping

Port‐wine birthmarks (PWBs) are congenital capillary malformations that can be located on any area of the body. Vascular features include vessel size, depth, and density, which can greatly differ between patients, individual lesions, and even sites within the same lesion. Previous studies have determined that the location of PWB lesions has impacted their clinical response to laser treatment.
Directions for research data management in UK Universities

The growth of collaborative research practices in a connected era, and latterly a rise in funder mandates, have fuelled a rapid increase in interest in sharing research data. Research data is recognised as being central to research and disseminating, sharing and enabling access to research data are all now seen as essential to research integrity. Making research data accessible does not simply facilitate validation, it also supports new research and innovation. Digital technology is making data sharing much easier. Starting out Openness is increasingly accepted as the default, while giving due respect to data protection, privacy and reasonable rights to first use. And so, as the highly regarded Royal Society report “Science as an Open Enterprise” says: “The conduct and communication of science needs to adapt to this new era of information technology. ” The opening up of research has also been supported by the transition to Open Access for peer reviewed research papers, and funders, publishers and universities have worked together to achieve Open Access. Open Access policies also encourage statements on access to the underlying research materials such as data. In the UK and further afield great strides have already been made to start to ensure that research data is well managed. The Australian National Data Service has coordinated developments for data infrastructure and, in the UK, Jisc has worked with numerous universities to develop solutions. But the management of research data is not solely the concern of universities; research funders also have a role and around the world data management plans and access to data beyond the research grant period are now commonly mandated. In the UK research councils have led the way with explicit policy requirements on research data and - alongside institutionally focused solutions for research data - there are disciplinary arrangements that cater for some data needs, such as the European Bioinformatics Institute and some of the research councils have disciplinary data archives Though the majority of research data is now in the digital domain, data does not have to be digital – the EPSRC 6 , for example, requires that “publicly-funded research data that is not generated in digital format will be stored in a manner to facilitate it being shared in the event of a valid request for access to the data being received”. Whilst this document focuses on digital data, much of what is said is applicable to all data. Universities that have begun to address research data management actively have found that they need a multidisciplinary team - people in the research office, the library and the IT department may all need to find effective ways to pool their skills. Progress is being made but research data management solutions in UK universities are still relatively immature and most universities only have partial solutions in place. Many would welcome shared solutions, and it is clear that shared services and more tightly coordinated infrastructure is required for more efficient and effective research data management
Posture-reading by men’s football goalkeepers and other factors in saving penalty kicks

ABSTRACT Penalty kicks are often decisive in football matches. Therefore, any technique that yields an advantage either in scoring or saving them is of great importance. Here we show the influence of a training programme for goalkeepers on the probability of defending penalties in men's football. Virtual training was used through an app that shows the shooter at the moment of setting the support foot on the ground and requiring the answer of which side (right or left) the ball will be directed at. Complemented with physical training, four sub 21 professional goalkeepers from Santarém, Brazil, developed the ability to correctly choose the side (left or right) at which the ball will be aimed. Sets of 800 penalties were kicked before (acting as control group) and after the training programme and it was found that, after training, the chances of saving penalty kicks or, at least, choosing the correct side, increase dramatically. It is concluded that the training programme improved the goalkeeper’s ability to choose the correct side. Other factors (laterality and height) were not found to be statistically significant.
Altering Focus Of Attention Effects Isometric Muscular Endurance And Heart Rate During Fitness Testing

ABSTRACT Subtle instructional changes that direct attentional focus can lead to changes in performance, potentially hindering a fitness assessment. An external attentional focus has been found to improve motor performance, however less is known about instructional effects on performance and the physiological response during an isometric endurance test. To better understand how attentional focus effects endurance fitness tests, two experiments were conducted. Experiment 1 showed that an external focus instruction (68.41 sec, SD = 34.20) led to significantly higher endurance performance compared to an internal instruction (60.22 sec, SD = 34.54). Experiment 2 revealed that heart rate during the internal condition (M = 117.51 bpm, SD = 14.19) was higher compared to the external (M = 114.17 bmp, SD = 13.19) and control (M = 115.40 bpm, SD = 16.85). Additionally, performance was greater during external instructions (M = 107.01 sec, SD = 46.35) compared to internal (M = 95.25 sec, SD = 38.19).
AN INTEGRATED PRODUCTION-INVENTORY MODEL FOR DETERIORATING PRODUCTION WITH DEFECTIVE ITEM REWORK AND JOINT MATERIAL REPLENISHMENT POLICY

ABSTRACT This paper considers an integrated production-inventory model which determines an optimal production cycle time and economic joint replenishment quantity of raw materials in a batch production system. The production process is assumed to be imperfect, and thus certain amount of item produced become defective. The defective items are assumed to be reworked immediately after the regular production ends and rework efforts are assumed to be performed under perfect condition. The objective is to minimize the expected total cost for the system over an infinite horizon. An algorithm to obtain an optimal or near optimal solution is presented. To demonstrate the model's fidelity, a numerical example is provided to illustrate the model. Sensitivity analysis is also performed and discussed. This deterministic model attempts to provide mangers with guidelines to evaluate the proper production cycle time and the purchase quantity of raw materials of an imperfect production process simultaneously under defective item rework and joint material replenishment policy.
Non-linear creep of polypropylene utilizing multiple integral

Multiple integral representation (MIR) has been used to represent studying the effect of temperature on the amount of nonlinear creep on the semi- crystalline polypropylene (PP) under the influence of axial elastic stress. To complete this research, the Kernel functions were selected, for the purpose of performing an analogy, and for arranging the conditions for the occurrence of the first, second and third expansion in a temperature range between 20 °C-60 °C, i.e., between the glass transition and softening temperatures, within the framework of the energy law. It was observed that the independent strain time increased non-linearly with increasing stress, and non-linearly decreased with increase in temperature, although the time parameter increased non-linearly with stress and temperature directly. In general, a very satisfactory agreement between theoretical and practical results on the MIR material was observed.

Gestures and body-movements in the teaching of singing: A survey into current practice in Australia and Germany

In order to investigate the use of gestures and body-movement as teaching and learning tools in one-on-one voice teaching a survey was conducted amongst members of two professional voice teaching organisations in Germany and Australia. The survey questionnaire implemented a terminology devised by the author that distinguished the movements encountered according to their pedagogical intent. It could be shown that a significant number of voice teachers in both surveyed countries regularly use various gestures to enhance and/or illustrate explanation and/or demonstration; and an almost equal number of voice teachers in both countries regularly encourage their students to use various gestures and/or body-movements to facilitate understanding and learning of physiological functions, thought concepts or musical ideas. Differences between the two respondent-groups were outweighed by commonalities and whilst the survey confirmed the prevalence of this teaching and learning tool it also highlighted the wide scope of possibilities and idiosyncrasies inherent in this issue.
Load-frequency control by hybrid evolutionary fuzzy PI controller

Power-system load-frequency control by fuzzy-PI (FPI) controller is proposed. During control, a fuzzy system is used to decide adaptively the proper proportional and integral gains of a PI controller according the area-control error and its change. To ease the design effort and improve the performance of the controller, design of the FPI controller by hybridising a genetic algorithm and particle-swarm optimisation, called FPI-HGAPSO, is proposed. FPI-HGAPSO is based on the hybrid of the genetic algorithm and particle-swarm optimisation. In FPI-HGAPSO, elites in the population of GAs are enhanced by particle-swarm optimisation and these enhanced elites are selected as parents for crossover and mutation operations. Simulations of the proposed evolutionary FPI-control approach on a multiarea interconnected power system with different kinds of perturbations are performed. The performance of the proposed approach is verified from simulations and comparisons.
How Do People Perceive Service Attributes at Transit Facilities?

Given the well-known fact that transit users perceive out-of-vehicle travel (walking, waiting, and transferring) as more onerous than in-vehicle travel, understanding what makes travelers' perceptions of the out-of-vehicle travel experience better is important for transit planners who seek to make public transit more attractive. Original survey data collected from 2,122 transit users regarding their perceptions of various attributes of service at 36 transit stops and stations in California were used to examine which attributes are important to transit users, as well as their satisfaction levels with each attribute, and to ascertain the relative needs for improvement of these attributes. The paper also examines how different sets of attributes that determine overall satisfaction vary by transit users' trip characteristics and demographics, such as age, sex, income level, race and ethnicity, auto availability, mode of travel, and frequency of transit use. In a series of ordered logit regression analyses, satisfaction levels for safety- and access-related variables were found to be more aligned with overall user satisfaction than were information- and reliability-related attributes and amenities. A similar result was found for various subpopulations—men, those making less than $15,000 per year, frequent riders, commuters, and those with an alternative mode of travel—but not for others. The analysis indicates that while safety is certainly the number-one priority for all transit users, travelers with different backgrounds on different modes of transit have different priorities for services and attributes to improve their transit experience.
Comparison Study on Different Compressibility Modifications of Turbulence Model in Supersonic Combustion Simulation

Supersonic combustion in two-model scramjet combustors of hydrogen and hydrocarbon fuel was, respectively, simulated using the in-house two-dimensional compressible, turbulent, and reacting flow code. Three kinds of compressibility modifications, namely, the dilatational compressibility, structural compressibility, and shock unsteadiness corrections, were incorporated into the k-ω shear stress transport (SST) model, respectively. In addition, the case that employs all the three corrections simultaneously was also performed to evaluate the coupling effect of these individual corrections. The steady laminar flamelet model was adopted to simulate the interaction between turbulence and chemical kinetics. The calculation results using compressibility modifications are in good agreement with experiments, validating the effectiveness and accuracy of the turbulent modification model. Results show that the dilatational compressibility correction model has good versatility in all conditions. The structural compressibility correction model demonstrates the best correction effect in near wall region but has no significant effect in the central flow field. The correction effect of the shock unsteadiness compressibility correction model is sensitive and proportional to the strength of shock wave. Moreover, the coupling case gives the most remarkable correction effect in most situations, indicating that the overlying effect may improve the prediction accuracy.
A new concept to cancel insertion phase variation in MMIC amplitude controller

A concept which keeps a very low insertion phase variation in an analog monolithic microwave IC (MMIC) amplitude controller is presented. This new approach, applicable to dual-gate FET (DGFET) variable-gain amplifiers, is to connect an active variable load to the second gate of the DGFET. This load makes use of a cold FET (with Vds=0 V) whose impedance varies depending on the amplitude command of the circuit. Then, the cold FET compensates the insertion phase change introduced by the DGFET attenuation control over a wide dynamic range. Based on this principle, a C-band GaAs MMIC attenuator for active antenna application has been designed. The phase variation versus gain is always lower than +or-2 degrees over a 20-dB gain/attenuation range. <<ETX>>
