Spatial Variability of Beach Impact from Post-Tropical Cyclone Katia (2011) on Northern Ireland’s North Coast
Authors: Anfuso Giorgio , Loureiro Carlos , Taaouati Mohammed , Smyth Thomas , Jackson Derek
Published: May 2020

In northern Europe, beach erosion, coastal flooding and associated damages to engineering structures are linked to mid-latitude storms that form through cyclogenesis and post-tropical cyclones, when a tropical cyclone moves north from its tropical origin. The present work analyses the hydrodynamic forcing and morphological changes observed at three beaches in the north coast of Northern Ireland (Magilligan, Portrush West’s southern and northern sectors, and Whiterocks), prior to, during, and immediately after post-tropical cyclone Katia. Katia was the second major hurricane of the active 2011 Atlantic hurricane season and impacted the British Isles on the 12–13 September 2011. During the Katia event, offshore wave buoys recorded values in excess of 5 m at the peak of the storm on the 13 September, but nearshore significant wave height ranged from 1 to 3 m, reflecting relevant wave energy dissipation across an extensive and shallow continental shelf. This was especially so at Magilligan, where widespread refraction and attenuation led to reduced shore-normal energy fluxes and very minor morphological changes. Morphological changes were restricted to upper beach erosion and flattening of the foreshore. Longshore transport was evident at Portrush West, with the northern sector experiencing erosion while the southern sector accreted, inducing a short-term rotational response in this embayment. In Whiterocks, berm erosion contributed to a general beach flattening and this resulted in an overall accretion due to sediment influx from the updrift western areas. Taking into account that the post-tropical cyclone Katia produced £100 m ($157 million, 2011 USD) in damage in the United Kingdom alone, the results of the present study represent a contribution to the general database of post-tropical storm response on Northern European coastlines, informing coastal response prediction and damage mitigation.
Pharmaceuticals Load in the Svihov Water Reservoir (Czech Republic) and Impacts on Quality of Treated Drinking Water
Authors: Datel Josef V. , Hrabankova Anna
Published: May 2020

An important component of micropollutants are PPCPs (pharmaceuticals and personal care products). This paper contains the results of the monitoring of surface water, groundwater and wastewater in the surrounding area of the Svihov drinking water reservoir. Over the period 2017–2019, over 21,000 water samples were taken and analyzed for 112 pharmaceuticals, their metabolites, and other chemicals. The results are discussed in detail for two streams with the highest observed concentration of PPCPs (Hnevkovice, Dolni Kralovice) and two streams with the highest water inflow into the reservoir, representing also the highest mass flow of PPCPs into the reservoir (Miletin, Kacerov). The overall analysis of the results shows that acesulfame, azithromycin, caffeine, gabapentin, hydrochlorothiazide, ibuprofen and its metabolites, oxypurinol, paraxanthine, and saccharin (on some profiles up to tens of thousands ng/dm3) attain the highest concentration and occur most frequently. The evaluation of raw water and treated drinking water quality showed the significant positive effect of water retention in the reservoir (retention time of 413 days) and also of the treatment process, so that the treated drinking water is of high quality and contains only negligible residues of few PPCPs near the detection limit of the analytical method used.

Published: May 2020

Compared to external loads from tributaries and sediment recycling, the role of waterbirds as phosphorus (P) sources in estuaries is overlooked. We performed monthly ship-based surveys of waterbird abundance in the Lithuanian part of the Curonian Lagoon, calculated their potential P excretion, and compared its relevance to the riverine inputs. Phosphorus excretion rates for the censused species were assessed accounting for variations of body weights, daily feces production and their P content, and assigning species to different feeding and nutrient cycling guilds. During the study period (March–November 2018), 32 waterbird species were censused, varying in abundance from ~18,000–32,000 (October–November) to ~30,000–48,000 individuals (June–September). The estimated avian P loads during the whole study period varied between 3.6 and 25 tons, corresponding to an area load between 8.7 and 60.7 mg P m−2. Waterbird release of reactive P to the system represented a variable but not negligible fraction (1%–12%) of total external P loads, peaking in June–September and coinciding with cyanobacterial blooms. This study is the first in the Baltic Sea region suggesting that waterbirds are potentially important P sources to phytoplankton in large estuaries, in particular, during low discharge periods.

Published: May 2020

Due to its Lagrangian nature, Smoothed Particle Hydrodynamics (SPH) has been used to solve a variety of fluid-dynamic processes with highly nonlinear deformation such as debris flows, wave breaking and impact, multi-phase mixing processes, jet impact, flooding and tsunami inundation, and fluid–structure interactions. In this study, the SPH method is applied to solve the two-dimensional Shallow Water Equations (SWEs), and the solution proposed was validated against two open-source case studies of a 2-D dry-bed dam break with particle splitting and a 2-D dam break with a rectangular obstacle downstream. In addition to the improvement and optimization of the existing algorithm, the CPU-OpenMP parallel computing was also implemented, and it was proven that the CPU-OpenMP parallel computing enhanced the performance for solving the SPH-SWE model, after testing it against three large sets of particles involved in the computational process. The free surface and velocities of the experimental flows were simulated accurately by the numerical model proposed, showing the ability of the SPH model to predict the behavior of debris flows induced by dam-breaks. This validation of the model is crucial to confirm its use in predicting landslides’ behavior in field case studies so that it will be possible to reduce the damage that they cause. All the changes made in the SPH-SWEs method are made open-source in this paper so that more researchers can benefit from the results of this research and understand the characteristics and advantages of the solution proposed.

Published: May 2020

Paradoxical reactions to tuberculosis (TB) treatment are characterized by an initial improvement of the clinical symptoms followed by clinical or radiological deterioration of existing tuberculous lesions, or by development of new lesions. Intestinal perforation in gastrointestinal TB can occur as a paradoxical reaction to antitubercular therapy. A 55-year-old man visited the outpatient department with lower abdominal pain and weight loss. He was diagnosed with intestinal TB and started antitubercular therapy. After 3 months of antitubercular therapy, a colonoscopy revealed improvement of the disease. Three days after the colonoscopy, the patient visited the emergency room complaining of abdominal pain. Abdominal computed tomography revealed extraluminal air-filled spaces in the pelvic cavity. We diagnosed a small bowel perforation and performed an emergency laparotomy and a right hemicolectomy with small bowel resection. This report describes the case of intestinal perforation presenting as a paradoxical reaction to antitubercular and provides a brief literature review.
Russian retail trade: institutional differences of trading companies as a factor of industry dynamics
Authors: Blokhin A.A. , Gridin R.V.
Published: May 2020

The article establishes: a) the fact of significant institutional differences between groups of companies in the Russian retail trade; b) the trend of increasing these differences in recent years. Criteria for structuring a sample of large companies in the form of a number of clusters that differ in their institutional strength and compete with each other are identified and tested. Among the criteria — presence in ratings, market coverage, participation in business associations, size and complexity of companies, etc. The mechanism of dominance of market leaders over other companies is revealed on the basis of the concept of institutional rent received by a group of leading companies from the income of «lagging» companies; the conditions for the transition of companies from one group to another are revealed. Based on the analysis of information about retail chains included in the selected clusters, estimates of their integrated financial and economic indicators are given; the comparative dynamics of the latter is revealed. The hypothesis about the significance of institutional differences in clusters for the dynamics of the industry as a whole and individual groups of companies is confirmed. The article substantiates proposals for forecasting such institutional transformations of markets, scenarios of which take into account the existing market hierarchies of dominant and other companies. Recommendations are put forward to improve state regulation of industry development, taking into account the existing market architecture.

Janus-Faced: Molecular Mechanisms and Versatile Nature of Renal Fibrosis
Authors: Arai Hiroyuki , Yanagita Motoko
Published: May 2020

Renal fibrosis is a major hallmark of CKD, regardless of the underlying etiology. In fibrosis development and progression, myofibroblasts play a pivotal role, producing extracellular matrix and interacting with various resident cells in the kidney. Over the past decade, the origin of myofibroblasts has been thoroughly investigated. Emerging evidence suggests that renal myofibroblasts originate from several cellular sources, including resident fibroblasts, pericytes, and bone marrow–derived cells. The contribution of resident fibroblasts is most crucial, and currently available data strongly suggest the importance of functional heterogeneity and plasticity of fibroblasts in kidney disease progression. Resident fibroblasts acquire distinct phenotypes based on their local microenvironment and exert multifactorial functions. For example, age-dependent alterations of renal fibroblasts make a significant contribution to the formation of tertiary lymphoid tissues, which promote local inflammation after injury in the aged kidney. In conjunction with fibrosis development, dysfunction of resident fibroblasts provokes unique pathologic conditions including renal anemia and peritubular capillary loss, both of which are major complications of CKD. Although renal fibrosis is considered detrimental in general, recent studies suggest it has beneficial roles, such as maintaining functional crosstalk with injured proximal tubular cells and supporting their regeneration. These findings provide novel insight into the mechanisms of renal fibrosis, which could be regarded as an adaptive process of kidney injury and repair. Precise understanding of the functional heterogeneity of resident fibroblasts and myofibroblasts has the potential to facilitate the development of novel therapeutics against kidney diseases. In this review, we describe the current perspective on the origin of myofibroblasts and fibroblast heterogeneity, with special emphasis on the dual aspects of renal fibrosis, both beneficial and detrimental, in CKD progression.

Published: May 2020

The aim of the study was to determine some heavy metals in human biological samples and to establish the hygienic significance of the obtained data in order to identify possible risks of adverse exposures and to assess the level of environmental pollution of the observed districts with heavy metals. Materials and methods. The studies were conducted in different areas of Baku. Concentrations of some heavy metals (Pb, Cd, Cr, Ni, Cu, and Zn) in human blood and hair, as well as in soil samples of residential, industrial and suburban areas were determined by atomic absorption spectrophotometry. Results. Different levels of heavy metals in the studied biological samples were established depending on the area of residence. The highest concentrations were registered in the people dwelling in the industrial area. At the same time, blood concentrations of metals did not exceed corresponding permissible values, regardless of the area of residence. Yet, metal concentrations in human hair with respect to the area of residence of our subjects followed a different pattern: concentrations of Pb, Cd, and Cr in hair exceeded the minimum values of their reference levels in the residents of all study areas while the concentrations of Ni, Cu, and Zn in hair turned out to be significantly higher than the regulatory levels in those living in the residential and industrial districts of the city. Consequently, the concentrations of all heavy metals measured in human hair of the people dwelling in the urban residential and industrial areas significantly exceeded the corresponding reference levels and correlated (r = 0.90-0.99) with high concentrations of those metals in local soils. Conclusions. The study results enabled us to conclude that a significant excess of the relevant hygienic standards for heavy metals both in human hair and soil in the study areas posed a certain risk of developing environment-related diseases from high outdoor exposures to toxic metals. They also proved the priority importance of testing hair as a reliable diagnostic medium for biological monitoring in hygienic studies.

Authors: Elfeky Wael , El-Afify Dalia R
Published: May 2020

Background: Postoperative atrial fibrillation (POAF) is associated with increased morbidity and mortality, and an inflammatory process is involved in its pathogenesis. We aimed to study the possible effect of alpha-lipoic acid (ALA) as an antioxidant on atrial fibrillation after cardiac surgery.

Methods: The study included ninety patients who underwent cardiac surgery, either valvular or coronary artery bypass grafting using cardiopulmonary bypass, and were randomized into two groups: Control and ALA groups. Blood samples were obtained to measure preoperative and postoperative levels of malondialdehyde (MDA), glutathione, C-reactive protein (CRP) and interleukin-6 (IL-6). The patients were monitored for the occurrence of atrial fibrillation until the day of discharge.

Results: POAF occurred in 33% in the control group versus 11% in the ALA group (p=0.011).  When compared to the control group, ALA significantly decreased the postoperative levels of MDA (4.78±0.91 vs. 5.36±1.03 nmol/ml; p= 0.006) CRP (19.44±3.14 vs. 26.56±6.29 mg/dl; p <0.001) and IL-6 (22.25±2.2 vs. 25.37±2.5 pg/ml; p< 0.001) while glutathione level increased significantly in patients who received ALA (26.4±4.59 vs. 23.44±5.11 mg/l; p= 0.005).

Conclusion: ALA may help in the prevention of atrial fibrillation following cardiac surgery through exerting antioxidant and anti-inflammatory effects.

D’Ambrosio (1996) points out that the History of Mathematics is an area that can bring many contributions to the Mathematics teaching The aim of this research was to analyze if and how the History of Mathematics is presented in high school Mathematics textbooks related to the “Right Triangle Trigonometry”. As theoretical reference we rely on the vulgata phenomena (CHERVEL, 1990) and on the possible pedagogical uses of the History of Mathematics. As a tool for analysis, we used the documentary research described in Gil (2002) in a sample of three High School Mathematics books collections, in quantitative and qualitative ways. As categories of qualitative analysis, we adapted Vianna’s (1995 apud BIANCHI, 2006) considerations regarding the uses of the History of Mathematics as motivation, information, didactic strategy and subject development. We observed that these categories were found in the textbooks and that they bring contributions, but they must be complemented by an adequate mediation by the Mathematics teacher.

Traditionally making of spring requires some operations on lathe machine like fixing and loosing checks, removing springs from the shafts. the solution to this problem is the design and fabrication of a multidimensional spring rolling machine. our project is simple by having a motor with pully to drive the shafts. The gap between the spring coil can be regulated by a proper arrangement that can guide the wire automatically. Design and fabrication of spring rolling machines include electric sewing motor, pulley, shaft, and belt.to overcome the limitations that are in the traditional lathe machine spring making process. This project gives suitable ways to produce springs of wire diameter up to 6mm, inner diameter up to 20mm.the proposed springs are capable of bearing maximum loads of 100N for three different materials like copper aluminum, steel.

There is a issue of rusting and brittle failure in building structures so there is a need of more durable structure for better performance. The durability of the structure is affected by the choice of the construction material only .But here our main focus is not only to increase the durability but we are also aiming towards increasing the strength of the structure which can be achieved by the confinement of the column. Studies shows that by confining the column, its strength can be increased significantly. From durability point of view, we have carried out the complete replacement of the natural coarse aggregate with the recycled aggregate in order to know its properties and suitability as a replacement material and to promote the idea of sustainable development. In the present paper, an experimental study is presented regarding the load carrying capacity of the unplasticized poly vinyl chloride (U-PVC) confined columns subjected to axial compressive load. The cylinders that are used for this study are M20 grade concrete cylinders which are made using the recycled coarse aggregates. The cylinders are confined using the U-PVC pipes of 2.5mm & 3.5mm thickness and epoxy resin was used to increase the bond strength between the concrete cylinders & the U-PVC pipes. The cylinders that are used in this study are of length 300mm & diameter 150mm. The concrete used in study are designed as per the latest versions of Indian Standard Code of Practice and are prepared after running various trial mixes. A total of 9 specimens were casted for this study out of which 6 specimens were confined using U-PVC pipes while the other 3 specimens were unconfined. The specimens were subjected to gradual compressive load in universal testing machine (UTM) upto the failure and the results were recorded. The results indicated significant increase in the load carrying capacity of the confined columns as compared to the unconfined columns.

Our experiment was conducted at a special dairy farm in Dakahlia Governorate between the periods (March –May 2018), This farm consisted of 400 Holestien cows; from the total of the animals only 210 lactating cows. The established experiment applied on 40 cows suffered from different types of anestrum detected by ultrasonography as follow (15 cows suffer from cystic ovary, 15 cows suffer from smooth inactive ovaries and 10 cows suffer from persist corpus luteum to study the effect of progesterone device insertion in dairy cattle and its effect in fertility. On day 0, cattle at random stage of estrous cycle received controlled internal drug release vaginal insert (CIDR).We left the CIDR in the vagina for seven days as we inject PGF2 on day 6 and remove the CIDR on day 7, blood samples were collected from 25 animals at zero day, 3rd, 7th and 9th day from the tail vein, and then we follow the estrous and detected the estrus cow for AI and apply ultrasonography for pregnancy diagnosis after 30 day from insemination From this study it was concluded that the use of progesterone for 7 days +i.m. injection of PGF2α in the 7th day can applied to dairy cattle to restart ovarian activity and it is an effective treatment for different infertility cases like cystic ovarian disease, persist corpus luteum and smooth in active ovaries. Moreover present study provides evidence for the importance of prior exposure to progesterone for cows to express estrous behavior, increase number of pregnant animals and increase conception rate.
Penemuan Hukum Oleh Hakim Perspektif Maqashid Syariah
Authors: Hidayatulah Rizki Pradana

Pasal 10 ayat (1) Undang-Undang Nomor 48 Tahun 2009 tentang Kekuasaan Kehakiman menentukan bahwa: “Pengadilan dilarang menolak untuk memeriksa, mengadili dan memutus suatu perkara yang diajukan dengan dalih hukum tidak ada atau kurang jelas, melainkan wajib untuk memeriksa dan mengadilinya”. Dari pasal tersebut, dapat dipahami bahwa hakim sebagai pelaksana kekuasaan kehakiman, wajib menerima, memeriksa, dan mengadili suatu perkara hingga selanjutnya memberikan putusan. sehingga dengan demikian, wajib hukumnya bagi hakim untuk menemukan hukumnya dalam suatu perkara walaupun dalam hal ini ketentuan hukumnya tidak jelas, kurang jelas, bahkan tidak ada. Metode penemuan hukum dalam Islam dikenal dengan istilah ijtihad, ijtihad dilakukan oleh para mujtahid. Maqâshid syarî’ah dijadikan salah satu metode dalam penemuan hukum agar putusan yang dibuat oleh hakim dapat memenuhi unsur manfaat dalam putusan. Maqâshid syarî’ah adalah sesuatu yang sangat penting yang harus dipahami oleh setiap hakim. Hakim pada zaman sekarang adalah sebagai wakil Tuhan dalam menerapkan hukum-hukum-Nya, penemuan hukum yang dilakukan oleh para hakim adalah ijtihad yang dilakukan oleh para mujtahid. Hakim adalah mujtahid pada zaman sekarang yang tugasnya menggali hukum dari sumber-sumber yang ada untuk diterapkan dalam kehidupan manusia.

Intercultural Development: Topics and Sequences
Authors: Savicki Victor , Adams Ingrid , Wilde April , Binder Frauke
Published: May 2020

This article presents a study which tracked reports of cultural events and topics deemed salient by university student sojourners over their semester of study abroad in an attempt to discover not only which topics were identified, but also the sequence in which the sojourners found those topics salient. Evidence for sequences of topic salience has implications for the education and support of sojourners both prior to departure and during exposure to a new culture.
The Georgetown Consortium Project: Interventions for Student Learning Abroad
Authors: Vande Berg Michael , Connor-Linton Jeffrey , Paige R. Michael
Published: May 2020

The Georgetown Consortium Project derived from Georgetown University's Office of International Programs along with several partner institutions. The large-scale and multi-year study was developed to understand components about U.S. student learning abroad. Of the three broad conclusions, the study revealed significant relationships between independent variables representing learner characteristics and program features and the intercultural and target language learning of students abroad. This article presents an analysis that concentrates on this conclusion. The relationships between student learning and certain independent variables support the argument that students learn most effectively abroad given proactive learning interventions.
Effects of an International Experience Requirement, Year in School, and Preferred Program Duration on Student Interest in Study Abroad
Authors: Richart Adrienne F.
Published: May 2020

This study was conducted at a large research university in the western U.S.A that shares many postsecondary educational institutions’ goal of increasing the number of students engaged in international experiences.  To achieve this goal, this institution has implemented an international experience requirement (IER) for approximately 30 disciplines.  The aim of this research was to 1) determine if there exists a difference in desired program duration between students who are subject to the IER and those are not, 2) establishwhether degree of interest in study abroad differs by year in school and 3)examine differences in degree of interest in study abroad by the existence or absence of the IER, preferred program duration, and the interaction of these factors. The author’s intent was to augment the cumulative understanding of the field of international education by exploring the area of required international experience, which to date has not been adequately studied. As institutions take measures to send larger proportions of their student body abroad this topic will become increasingly relevant. Existing studies in this area are discussed below.
