THE IMPACT OF EXCHANGE RATE ON STOCK MARKET INDICES

The relationship between exchange rate and stock indices has risen many eyebrows so far. These two fundamental financial markets have a significant role in international business all around the globe. Furthermore, exchange rate is one of the most important indicators that rules in the decision-making process in all firms. In order to understand the relationship between the two variables this paper tried to investigate the relationship between exchange rate of USD/TL and BIST-100 index in Turkish stock market. The data have been collected from January 2009 to March 2020 based on monthly data. VAR model is applied in the study to exam the connections between the variables. The findings reveal that there is only a one-way causality between the variables. Nevertheless, the impulse response results show a negative impact from the shocks of each variable to another.
Effects of Successive Peak Flow Events on Hyporheic Exchange and Residence Times

Hyporheic exchange is a crucial control of the type and rates of streambed biogeochemical processes, including metabolism, respiration, nutrient turnover, and the transformation of pollutants. Previous work has shown that increasing discharge during an individual peak flow event strengthens biogeochemical turnover by enhancing the exchange of water and dissolved solutes. However, due to the nonsteady nature of the exchange process, successive peak flow events do not exhibit proportional variations in residence time and turnover, and in some cases, can reduce the hyporheic zones' biogeochemical potential. Here, we used a process‐based model to explore the role of successive peak flow events on the flow and transport characteristics of bedform‐induced hyporheic exchange. We conducted a systematic analysis of the impacts of the events' magnitude, duration, and time between peaks in the hyporheic zone's fluxes, penetration, and residence times. The relative contribution of each event to the transport of solutes across the sediment‐water interface was inferred from transport simulations of a conservative solute. In addition to temporal variations in the hyporheic flow field, our results demonstrate that the separation between two events determines the temporal evolution of residence time and that event time lags longer than the memory of the system result in successive events that can be treated independently. This study highlights the importance of discharge variability in the dynamics of hyporheic exchange and its potential implications for biogeochemical transformations and fate of contaminants along river corridors.
Nonlinear transport properties and Joule heating effect in charge ordered LuFe2O4

The nonlinear current-voltage (I-V) relation of charge ordered (CO) LuFe2O4 has been studied in the temperature range from 220 to 520 K. Strong nonlinear effects are identified in the CO state and disappear in high-temperature charge disordered state. Alternation of the CO state under applied electric field is directly revealed by in situ transmission electron microscopy observations. Careful investigations of time-dependent resistance under the applied electric field near the threshold value (Eth) often show three distinct steps for the nonlinear transitions. The CO collapse likely at a critical conductivity yields a sharp drop in resistance.
Improved Room Acoustics Quality in Meeting Rooms: Investigation on the Optimal Configurations of Sound-Absorptive and Sound-Diffusive Panels

This work deals with the improvement of the room acoustic quality of two medium sized meeting rooms through the investigation of the optimal placement of absorption and diffusive panels on the walls and ceiling. Acoustic measurements have been carried out in the existing untreated rooms with ODEON 13 room acoustics measurement and prediction software, and the Adobe Audition plugins Aurora. Simulations of different combinations of sound absorption and diffusion treatments have been carried out with the updated version of the software, ODEON 15. The panels were positioned in the meeting rooms following the guidelines of the DIN 18041 standard and the scientific literature. The results advise the application of absorptive materials on the ceiling or around the borders, creating a reflective middle area, and on the upper part of one the lateral walls, including the rear wall. Configurations with diffusers do not generally bring significant improvements. The Speech Transmission Index (STI) is a less sensitive parameter for the different acoustic scenarios, compared to Reverberation Time (T) and Clarity (C50). The research also outlined a design workflow, useful to successfully design meeting rooms and rooms for speech in general, which allows to determine the optimal number and location of acoustic panels and to minimize the costs.

Histological, Micrometrical and Histochemical Studies on the Testes of Large White Yorkshire Pig (Sus scrofa domesticus)

The study has been conducted on the testes of 10 adult Large White Yorkshire pig (1.5-2) years of age. The testis was surrounded by a capsule made up of dense irregular connective tissue comprising three layers viz., outer visceral layer of tunica vaginalis, middle tunica albugenia and inner tunica vasculosa. The connective tissue trabeculae were extended from the capsule and divided the parenchyma of the testis into number of lobules and consisted of collagen, elastic and reticular fibers along with rete testis and blood vessels. The Periodic Acid–Schiff shows strong affinity in basement membrane of seminiferous tubules and tunica albuginea with a moderate activity in Leydig cells. The Alcian blue shows strong affinity in basement membrane of seminiferous tubule and weak activity was observed in tunica albuginea and interstitial tissue. The different histomorphometrical parameters with regard to thickness of testicular capsule, diameter and height of seminiferous tubules were found to be higher in the left testicle.
Site-specific incidence of ring-related injuries in Rufous Fantails Rhipidura rufifrons

ABSTRACT Although colour-ringing is generally considered safe, a small proportion of avian species experience significant ring-related injuries. We report the first description of ring-related injuries in a rhipidurid flycatcher, the Rufous Fantail, and show that, in a population on Rota in the Northern Mariana Islands, switching from plastic to metal rings reduced but did not eliminate ring-related injuries. Over 30% of Rufous Fantails experienced severe injuries (tarsal swelling and leg loss) while wearing plastic rings and 11.7% experienced injuries while wearing metal rings. Injuries were not caused by improper fit of the rings and the use of metal rings in a separate population in Iluka, Australia, did not appear to cause any injuries. We suggest that injuries are caused by the accumulation of spider silk around the tarsus. Rufous Fantails may be more susceptible to injuries on Rota than in Iluka due to the frequency with which they encounter spider webs. We recommend avoiding the use of plastic rings on rhipidurids and related species and, more specifically, developing alternative marking schemes for the potential reintroduction of Rufous Fantails to Guam, where spider webs are abnormally abundant.
Association between Follicle Stimulating Hormone (FSH), Vascular Endothelial Growth Factor (VEGF), and Caspase-3 of Follicular Fluid with The Number of Mature Oocytes of Patients underwent In Vitro Fertilization Program

Background: Determine the levels of FSH, VEGF, and Caspase-3 in follicular fluid and the correlation with the number of mature oocytes of IVF program patients. Methods: Measurement of FSH, VEGF, and Caspase-3 in follicular fluid of patients who underwent IVF was done. Results: We found higher FSH level [(6.44 vs 2.16 ng/mL (p<0.015) and lower VEGF level [(2229.28 ± 841.8 vs 3566.77 ± 432.50 pg/ml (p<0.001)] of follicular fluid in the group of mature oocytes 35. No significant difference of Caspase-3 level [0.09 vs 0.08 ng/ml (p=0.430)] was found in mature oocytes <5 and 35 group, respectively. We found significant positive correlation of FSH levels (r 0.657, p<0.001), significant negative correlation of VEGF levels (r -0.656, p<0.001), and no correlation of caspase-3 (r -0.116, p 0.496) with the number of mature oocytes. Conclusions: Follicular fluid FSH levels were positively correlated, VEGF levels were negatively correlated, and Caspase-3 levels were not correlated with the number of mature oocytes.
Nightmare Distress, Beliefs about Nightmares, and Personality

A variety of factors contribute to nightmare distress; in addition to nightmare frequency also beliefs about nightmares can be associated with heightened nightmare distress. The study investigated the personality correlates of beliefs about nightmares and whether these beliefs mediate the relationship between gender, neuroticism, and nightmare distress. Overall, 1214 persons (716 women, 498 men) completed the dream questions and the Big Five Personality Inventory online. The beliefs about nightmares scale was related to neuroticism and openness to experience. However, the regression analysis indicated that a variety of factors like beliefs about nightmares, gender, neuroticism, and agreeableness contributed to nightmare distress independently from nightmare frequency. Given the marked influence of beliefs about nightmares on nightmare distress, it would be very interesting to study the effect of psycho-education presenting modern etiological models of nightmares on nightmare distress.
An XROMM Study of Food Transport and Swallowing in Channel Catfish

Synopsis Most predatory ray-finned fishes swallow their food whole, which can pose a significant challenge, given that prey items can be half as large as the predators themselves. How do fish transport captured food from the mouth to the stomach? Prior work indicates that, in general, fish use the pharyngeal jaws to manipulate food into the esophagus, where peristalsis is thought to take over. We used X-Ray Reconstruction of Moving Morphology to track prey transport in channel catfish (Ictalurus punctatus). By reconstructing the 3D motions of both the food and the catfish, we were able to track how the catfish move food through the head and into the stomach. Food enters the oral cavity at high velocities as a continuation of suction and stops in the approximate location of the branchial basket before moving in a much slower, more complex path toward the esophagus. This slow phase coincides with little motion in the head and no substantial mouth opening or hyoid depression. Once the prey is in the esophagus, however, its transport is surprisingly tightly correlated with gulping motions (hyoid depression, girdle retraction, hypaxial shortening, and mouth opening) of the head. Although the transport mechanism itself remains unknown, to our knowledge, this is the first description of synchrony between cranial expansion and esophageal transport in a fish. Our results provide direct evidence of prey transport within the esophagus and suggest that peristalsis may not be the sole mechanism of esophageal transport in catfish.
Identity Fusion and Adjustment in International Students at U.S. Colleges and Universities

The present study explores how international students’ (IS; N = 169; Mage = 19.81 years, 36% male) identity fusion, the extent to which they feel connected with a particular social group, is concurrently and longitudinally correlated with belonging, loneliness, well-being, and perceived social support. IS reported higher fusion with other IS than with domestic students (DS). Fusion with IS at Time 1 (T1) was associated with greater IS support at T1 and Time 2 (T2). Fusion with DS was positively correlated with T1 belonging, well-being, and DS support at both time points, and was negatively linked with loneliness at T1 and T2. IS and DS fusion also interacted in predicting T1 belonging and loneliness. Students with proportionally greater DS than IS fusion reported greater DS support, and proportionally greater IS fusion was related to greater IS support. Discussion centers on promoting adjustment and intergroup relationships in higher education.

Prophetic Communication: Transcendental Dimension In Islamic Philanthropy Messages

Indonesia Islamic philanthropy had been growing tremendously. Trends in institutions platforms in managing Islamic philanthropy brought the divergence of channel message distribution. Those institutions made convergence interdisciplinary innovation. Islamic philanthropy institutions obligate to distribute the message in an ethical manner. They employed prophetic communication values in engaging the public sphere with persuasive communication commonly. Prophetic communication design is a custom to promote transcendental dimension of contemporary communication praxis. The prophetic term uses the cognition proximity design refers to Prophet Muhammad as a role model. This research was conducted to get an overview of the prophetic communication representation in the Islamic philanthropic messages distribution. Analytical techniques use qualitative document analysis. The subject in this research is the display of text on the site of Islamic philanthropic foundations official website Rumah Zakat, Yayasan Dana Al-Falah, and Lembaga Manajemen Infaq. The theme categories enrich found with selective coding. The results of the analysis are discussed using the concepts of prophetic communication, message production theory, goal-plan-action theory, action-making theory, and cognitive dissonance theory. For further research could obtain from the communication management of more specific philanthropic objects.
Large Variations in N2O Fluxes from Bioenergy Crops According to Management Practices and Crop Type

Field N2O emissions are a key point in the evaluation of the greenhouse gas benefits of bioenergy crops. The aim of this study was to investigate N2O fluxes from perennial (miscanthus and switchgrass), semi-perennial (fescue and alfalfa) and annual (sorghum and triticale) bioenergy crops and to analyze the effect of the management of perennials (nitrogen fertilization and/or harvest date). Daily N2O emissions were measured quasi-continuously during at least two years in a long-term experiment, using automated chambers, with 2–5 treatments monitored simultaneously. Cumulative N2O emissions from perennials were strongly affected by management practices: fertilized miscanthus harvested early and unfertilized miscanthus harvested late had systematically much lower emissions than fertilized miscanthus harvested late (50, 160 and 1470 g N2O-N ha−1 year−1, respectively). Fertilized perennials often had similar or higher cumulative emissions than semi-perennial or annual crops. Fluxes from perennial and semi-perennial crops were characterized by long periods with low emissions interspersed with short periods with high emissions. Temperature, water-filled pore space and soil nitrates affected daily emissions but their influence varied between crop types. This study shows the complex interaction between crop type, crop management and climate, which results in large variations in N2O fluxes for a given site.
Biochemical Properties and Urease, α-amylase Inhibitory Effects of Ocimum basilicum L. (Reyhan)

With the understanding of the role of antioxidants in preventing degenerative and age-related diseases caused by oxidative stress, and taking into account the multitude of pharmacological applications such as antidiabetic, antifungal, cardioprotection, immunostimulant, interest in plants rich in this respect has increased. Ocimum basilicum L. (purple) is a one-year, fragrant spice herb with its own aroma. In this study, chemical characterization of Ocimum basilicum plant was performed and inhibition effects on urease and a-amylase were investigated. Total phenolic content of Ocimum basilicum leafs ethanolic and water extracts were 320.08±2.03, 388.15±1.05 mg GAE/100g; total flavonoids were 282.57±1.12, 307.75±0.89 mg QE/100g; antioxidant capacity of samples were 0.46±0.01 and 0.52±0.02 mM Fe+2/ mg extract, 0.46±0.01; IC50 values of urease were 18.77±0.22, 20.19±0.15 μg/mL and IC50 values of α-amylase were 0.47±0.01, 0.42±0.01 μg/mL, respectively. It is determined that ethanolic extract of leaves is rich in linalool, linolenin, phytol and α-humulene. The data show that the leaves of the plant may be effective on two important diseases such as Diabetes mellitus and H. pylori.
Alternative paths to improved word-problem performance: An advantage for embedding prealgebraic reasoning instruction within word-problem intervention.

The purpose of this study was to explore the paths by which word-problem intervention, with versus without embedded pre-algebraic reasoning instruction, improves word-problem performance. Students with mathematics difficulty (MD; n = 304) were randomly assigned to a business-as-usual condition or one of two variants of word-problem intervention. The pre-algebraic reasoning component targeted relational understanding of the equal sign as well as standard and nonstandard equation solving. Intervention occurred for 16 weeks, 3 times per week, 30 min per session. Sequential mediation models revealed main effects, in which each intervention condition significantly and substantially outperformed the business-as-usual condition, corroborating prior research on the efficacy of schema word-problem intervention. Yet despite comparable effects on word-problem outcomes between the two word-problem conditions, the process by which effects accrued differed: An indirect path via equal-sign understanding and then equation solving was significant only for the word-problem intervention condition with embedded pre-algebraic reasoning instruction. Additionally, the effect of this condition on equal-sign reasoning was strong. Given the link between equal-sign reasoning for success with algebra and the importance of algebra for success with advanced mathematics, results suggest an advantage for embedding pre-algebraic reasoning instruction within word-problem intervention.

Back to the future of Knowledge Management Systems off the beaten paths

PurposeThe evolution of Knowledge-Management (KM)-related literature has highlighted that Knowledge Management Systems (KMSs) have undergone massive changes in collaborative environments. Information-Systems-enabled KM seems to be the necessary response to the recent challenges posed by globalisation and technology dynamics to both large companies (LCs) and small and medium enterprises (SMEs). Design/methodology/approachThis paper provides a systematic review about KMSs to offer an analytical overview of their role in supporting innovative forms of knowledge translation occurring in collaborative relationships. A sample of 129 papers was selected and analysed according to three perspectives: unit of analysis (LCs, SMEs), phases of the KM process (adoption, translation) and topic area (KM Practices, KM Tools, KMSs). FindingsThe findings highlight five literature gaps: (1) the role of KM practices supporting knowledge translation; (2) the impact of the alignment among KM practices, firm's complexity, dimension and culture on KM process; (3) the effect of KM tools on knowledge translation; (4) the variety of KMSs exploited in both LCs and SMEs; and (5) the alignment between organisational structure and information systems in KM context. Accordingly, 13 research questions were formulated.Originality/valueThe proposed research questions define a formal research agenda that could steer further research efforts about the KMS topic for improving the body of knowledge in the KM field. Scientific literature is currently lacking a contribution assessing the role of KMSs in supporting innovative forms of knowledge translation that occur in collaborative relationships.
