Authors: MELEKOĞLU Tuba , IŞIN Ali , ÜNLÜ Gürcan
Published: June 2018

Bu çalışmanın amacı;
okuldaki beden eğitimi derslerine ek olarak okul dışındaki fiziksel
aktivitelere katılan 13-14 yaşındaki adölasanların akciğer hacim ve
kapasitelerini, okul dışı fiziksel aktivitelere katılmayan adölasanlarla kıyaslamaktır.
Antrenman geçmişlerine, sağlık durumlarına, fiziksel özelliklerine bağlı ön
değerlendirme sonrasında atletizm, futbol, hentbol, yüzme gibi branşlarda en az
5 yıllık antrenman geçmişine sahip 28 sporcu ve antrenman geçmişi bulunmayan,
sporcularla benzer fiziksel özelliklere sahip 28 sedanter adölasan katılmıştır.
Akciğer hacim ve kapasitelerini belirlemek için spirometre ile vital kapasite,
zorlu vital kapasite ve maksimal istemli ventilasyon ölçümleri yapılmıştır.
Verilerin istatistiksel değerlendirilmesinde SPSS v.24 kullanılmıştır. Beden
eğitimi derslerine ek olarak okul dışında da takım antrenmanlarına katılarak
fiziksel aktivite düzeylerini arttıran adölasanların sadece beden eğitimi
derslerine katılan adölasanlara karşın sırasıyla vital kapasiteleri (3,57±0,63 lt'ye
karşın 2,72±0,56 lt), zorlu vital kapasiteleri (3,50 ± 0,64 lt'ye karşın 2,70 ±
0,56 lt) ve maksimal istemli ventilasyon (127,91 ±29,48 lt/dk, 109,10 ± 19,07 lt/dk)
değerleri anlamlı olarak yüksek bulunmuştur (p<0,001). Okul dışında da
fiziksel olarak aktif adölasanların vital kapasiteleri % 31,50, zorlu vital
kapasiteleri % 29,82 ve maksimal istemli ventilasyon değerleri % 17,24 daha
yüksek bulunmuştur. Sonuçlar, adölasan ve ergenlik dönemindeki düzenli
aktivitenin akciğer hacimlerini ve kapasitelerini artırdığını göstermektedir.
Bu nedenle, adölasanların okuldaki beden eğitimi ders saatlerinin ve/veya okul
dışındaki fiziksel aktivite düzeylerinin arttırılması solunum sistemi ve
sağlığı üzerine önemli katkılar sağlayacağı öngörülmektedir.
PERCEPCIONES DE UN GRUPO DE FONOAUDIÓLOGOS COLOMBIANOS SOBRE SU ROL PROFESIONAL EN EDUCACIÓN INCLUSIVA
Authors: Quintero Uribe Jhon Fredy , Montoya Otalvaro Juliana Andrea
Published: June 2018

El fonoaudiólogo trabaja por el bienestar comunicativo en diferentes escenarios, uno de ellos el educativo, en donde se presenta una relación más directa y estructurada entre la comunicación y el aprendizaje. El rol del fonoaudiólogo en educación inclusiva fue legitimado por el Decreto 366 de 2009 del Ministerio de Educación Nacional y hasta el año 2017 con el Decreto 1421 de la misma entidad, se reglamentó la atención educativa a la población con discapacidad sin explicitar la participación del profesional de fonoaudiología en el sistema educativo. Objetivo: Estudiar las percepciones de un grupo de fonoaudiólogos de diferentes regiones de Colombia que trabajan en educación inclusiva, sobre su rol profesional y condiciones laborales en este escenario. Método: El estudio fue de enfoque cualitativo, nivel exploratorio, muestreo por conveniencia y trabajo de campo mediante entrevista semiestructurada remota. Resultados: Los entrevistados expresan que el rol es muy poco reconocido, que hay malas condiciones labo ales y que es importante contar con mayor formación en educación inclusiva para poder desempeñarse en dicho escenario. Discusión: Los resultados son coherentes con estudios previos por lo que deben reconocerse pocas transformaciones históricas que invitan a la reﬂexión de cara a la nueva normativa. Se reconoce la no exhaustividad del estudio y se invita a mantener la reﬂexión para impulsar el fortalecimiento del rol y reconocimiento del fonoaudiólogo en educación inclusiva.

The effect of “Internet of Things” on supply chain integration and performance: An organisational capability perspective
Authors: De Vass Tharaka , Shee Himanshu , Miah Shah J
Published: June 2018

The Internet of things (IoT) is a next generation of Internet connected embedded ICT systems in a digital environment to seamlessly integrate supply chain and logistics processes. Integrating emerging IoT into the current ICT systems can be unique because of its intelligence, autonomous and pervasive applications. However, research on the IoT adoption in supply chain domain is scarce and acceptance of the IoT into the retail services in specific has been overly rhetoric. This study is drawn upon the organisational capability theory for developing an empirical model considering the effect of IoT capabilities on multiple dimensions of supply chain process integration, and in turn improves supply chain performance as well as organisational performance. Cross-sectional survey data from 227 Australian retail firms was analysed using structural equation modelling (SEM). The results indicate that IoT capability has a positive and significant effect on internal, customer-, and supplier-related process integration that in turn positively affects supply chain performance and organisational performance. Theoretically, the study contributes to a body of knowledge that integrates information systems research into supply chain integration by establishing an empirical evidence of how IoT-enabled process integration can enhance the performance at both supply chain and organisational level. Practically, the results inform the managers of the likely investment on IoT that can lead to chain’s performance outcome.

Peran Stasiun Televisi dalam Pengembangan Demokrasi, Ekonomi dan Politik di Indonesia
Authors: AB Subhan
Published: June 2018

Dewasa ini televisi, sebagai bagian dari komunikasi massa di asumsikan memegang posisi penting dalam masyarakat. Peranan penting televise telah menjadikan media ini berkembang pesat dalam 20 tahun ini. Televisi hadir sebagai alat sosial, politik, budaya, bahkan sebagai sebuah industri informasi dari sebuah perusahaan. Sebagai industri, televisi menjanjikan keuntungan cukup besar bagi pemiliknya, bersaing secara kompetitif.Kini televisi tidak lagi menjadi media yang berorientasi untuk memenuhi kebutuhan masyarakat dalam hal informasi dan hiburan yang sehat, melainkan lebih dominan pada keuntungan ekonomi kapitalis, kekuatan pasar secara kompetitif. Dampaknya masyarakat ‘kering’ informasi yang ditampilkan secara both of side dan aktual. Pemberitaan media televisi dikemas sedemikian rupa dengan metode agenda setting. Hal ini menjadi dilematis tersendiri bagi para penggiat jurnalistik: antara publik atau kepentingan pemilik? Berita-berita yang disajikan dan ditayangkan oleh media televisi lebih berorientasi kepada pentingan pemilik, bukan kepentingan publik. Sementara itu, kapitalisasi dalam industri media televisi terus menggurita. Ada pemilik tunggal untuk beberapa stasiun televisi yang menyalahi regulasi dari penyiaran di Indonesia. Kendati sudah diatur sedemikian baiknya, namun konglomerasi dalam industri pertelevisian di Indonesia belum dibenahi. Politik dan ekonomi menjadi alasan utama sehingga regulasi penyiaran di Indonesia belum mampu diterapkan seperti di Eropa dan Amerika Serikat.
Recent progress in confined atoms and molecules: Superintegrability and symmetry breakings
Authors: Ley Koo Eugenio
Published: June 2018

This review article has the antecedents of Jaskolski’s 1996 Physics Report Confined Many-electron Systems , the fifteen chapters on the Theory of Confined Quantum Systems in Vols. 57 and 58 of 2009 Advances in Quantum Chemistry, and the nine chapters of the 2014 Monograph “Electronic Structure of Confined Quantum Atoms and Molecules”. In this contribution the last two sets of reviews are taken as the points of reference to illustrate some advances in several lines of research in the elapsed periods. The recent progress is illustrated on the basis of a selection of references from the literature taking into account the confined quantum systems, the confining environments and their modelings; their properties and processes, emphasizing the changes due to the confinement; the methods of analysis and solutions, their results including confiability and accuracy; as well as applications in other areas. The updated and current works of the Reviewer are also presented. The complementary words in the title apply to the simplest atom in its free configuration and to the harmonic oscillator quantum dot because they admit more exact solutions than the number of their degrees of freedom; and to their many-electron and confined counterparts, due to their additional interactions and changes in boundary conditions.
A method to obtain orientation curves in Euler space for a seccond diffraction process in polycrystals
Authors: Palacios Gómez Jesús , Salat Figols R.S. , Kryshtab T.
Published: June 2018

A method is presented to obtain the orientation curve in the Eulerian space, of crystallites which diffract in one point of a Debye-Scherer ring in a second diffraction process. The incident beam is therefore the reflected beam of a previous diffraction process, and the sample has a general orientation for a pole figure measurement, given as usual by two angles, χ  around the sample Y axis, and φ around the sample normal. Two solutions are found for all secondary reflections. The method proposed here was outlined somewhere else for the measurement of pole figures by neutron diffraction [1], and here important improvements are made, especially regarding the mathematical methods.

METODYKA WERYFIKACJI CECH RYNKOWYCH WPŁYWAJĄCYCH NA POZIOM CEN TRANSAKCYJNYCH I JEJ ZASTOSOWANIE W PROCESIE SCALANIA GRUNTÓW
Authors: Siejka Monika
Published: June 2018

Wielofunkcyjność obszarów wiejskich w różnych dziedzinach gospodarki wymusza konieczność uwzględniania tego faktu w pracach scalania i wymiany gruntów. Zmiana struktury własności i użytkowania gruntów korzystnie wpływa nie tylko na rozwój rolnictwa, lecz także na rozwój funkcji pozarolniczych obszaru objętego scaleniem. Podstawą prawidłowego wykonania scalenia i wymiany gruntów jest przeprowadzenie szacunku gruntów wolnego od błędów i wad. Wobec coraz lepiej rozwijającego się rynku nieruchomości, również w zakresie gruntów rolnych, zasadne jest wykorzystanie cen transakcyjnych do szacunku gruntów na potrzeby ich scalenia i wymiany. Rozwiązanie to ułatwi wzajemne rozliczenia między uczestnikami scalenia, pozwoli na obrót gruntami w procesie scalenia, a także wpłynie na dokładność określania wartości gruntów posiadanych przez uczestników scalenia, szczególnie w aspekcie rozwoju funkcji pozarolniczych. Obowiązujące obecnie przepisy prawne dopuszczają wycenę w oparciu o ceny transakcyjne w sytuacji nieokreślenia zasad szacunku przez uczestników scalenia. Przepisy te nakładają jednak istotne ograniczenie, którym jest wykorzystanie cen uzyskiwanych w sprzedaży państwowych nieruchomości rolnych. Tak oszacowana wartość nie spełnia znamion wartości rynkowej. Podjęte w pracy badania, przeprowadzone na obszarze o charakterze rolniczym, potwierdzają tezę, że poziom cen transakcyjnych nieruchomości rolnych zależy od cech charakterystycznych dla lokalnego rynku nieruchomości. Chcąc uniknąć błędów wadliwego oszacowania nieruchomości z powodu niewłaściwego wskazania liczby i rodzaju cech decydujących o poziomie cen, należy przeprowadzić ich weryfikację.

Rozwój transportu samochodowego przyczynił się do budowy nowoczesnej infrastruktury drogowej. Planowanie nowych dróg, szczególnie szybkiego ruchu, wywiera jednak znaczący wpływ na strukturę przestrzenną terenów niezurbanizowanych. Przeprowadzenie tak dużego przedsięwzięcia, którym jest budowa nowej drogi ekspresowej, pociąga za sobą wiele trwałych skutków dotyczących zarówno przestrzeni, środowiska, jak i aspektów społecznych i gospodarczych. Gospodarowanie przestrzenią na obszarach wiejskich wymaga kompleksowego ujęcia elementów struktury przestrzennej z uwzględnieniem wszystkich czynników społecznych, gospodarczych i przyrodniczych. W artykule przedstawiono przestrzenne oraz społeczno-gospodarcze skutki budowy drogi ekspresowej S7 na odcinku Olsztynek – Nidzica wraz z obwodnicą Olsztynka w ciągu drogi ekspresowej S51 na przykładzie wsi Sudwa. Badania dotyczyły analizy stanu władania i użytkowania gruntów oraz rozdrobnienia i rozproszenia gruntów indywidualnych. Oceniono również wpływ wybudowanej drogi ekspresowej na strukturę przestrzenną wsi Sudwa oraz strukturę przestrzenną gruntów wybranego gospodarstwa. Społeczno-gospodarcze skutki budowy drogi określono na podstawie przeprowadzonych badań sondażowych wśród mieszkańców wsi Sudwa i okolic.

W krajach Europy Zachodniej coraz częściej mieszkańcy miast chcą współdecydować o wyglądzie przestrzeni publicznych. Budżety obywatelskie cieszą się coraz większą popularnością wśród samorządów. Budżet partycypacyjny jest inicjatywą o ogromnych możliwościach i może stać się początkiem zmian w systemie zarządzania miastem. W polskich miastach jest wciąż zbyt mało zieleni. W Olsztynie udział terenów zieleni (włączając las miejski) w ogólnej powierzchni miasta wynosi ok. 24%. Mimo wykonywanych nasadzeń kompensacyjnych i innych działań podejmowanych w celu zwiększenia liczby terenów zieleni, obszarów tego typu jest w mieście wciąż zbyt mało. W artykule przedstawiono propozycję wydzielenia w budżecie obywatelskim zielonego budżetu, ze względu na niski, na poziomie ok. 13%, udział projektów dotyczących zieleni. Zaproponowano także działania, które można zrealizować w ramach „zielonego budżetu” partycypacyjnego w Olsztynie.

Doing gender and age: The case of informal elderly care in the Czech Republic
Authors: Dudová Radka
Published: June 2018

This article seeks to describe and explain some of the factors behind the prevalence of women in informal care for seniors. It presents a qualitative study of women who are caring for a frail elderly parent in the Czech Republic. Care is seen as a space where gender and other intersecting identities are performed and this has specific subjective, structural and material consequences. The author draws on biographical interviews with women caregivers and shows how they “do gender and age” in their narratives of how and why they made the decision to provide care and how they actually provide care. The author identifies situations and circumstances in which gender categories and gender relations shift and are destabilised by changes in society. The Czech Republic is a country with a history of state socialism and with traditionally large numbers of women in the workforce, but it also has a highly traditional gender culture.
Cross-Level Dynamics of Collaboration and Conflict in Multi-Party Systems: An Empirical Investigation Using a Behavioural Simulation
Authors: Curseu Petru Lucian , Schruijer Sandra
Published: June 2018

Multiparty systems bring together various stakeholder parties and their representatives and offer a platform for sharing their diverse interests, knowledge and expertise in order to develop and realize joint goals. They display complex relational dynamics in which within-party interactions (interpersonal interactions within each stakeholder party) as well as between-party interactions (interactions between the stakeholder parties) intertwine to generate bottom-up and top-down influences. We investigate these influences in a behavioural simulation. Our results show that changes in task conflict at the stakeholder party level positively predict changes in perceived collaborativeness in the overall system, while changes in relationship conflict at the stakeholder party level positively predict changes in perceived conflictuality in the system. Moreover, we show that changes in perceived overall conflictuality leads to a proportional change in relationship conflict experienced within the stakeholder parties.

Published: June 2018

The role of strategic management is to handle the day-to-day needs of the firms with respect to current events of fluctuating markets so that they can effectively reach to their pre-planned, long-term goals. This study aims to explain the steps taken to design a new conceptual framework in the strategic management department of the National Iranian Gas Export Company (NIGEC), as well as the main components of the conceptual framework. It first goes through the logic behind the techniques applied to design this conceptual framework, and then each component is explained as to why it works as part of an integrated conceptual framework. This new framework is part of a change regime in the organisation along with the whole oil industry in Iran aimed at contributing to directing the organisations confronted with rapidly altering environments. The insights of this study shed light on the basics of designing an adjusted conceptual framework for managers and researchers, and all companies faced with constant internal and external challenges and other characteristics of modern organisations.
Impact of a New Deep Vertical Lime Placement Practice on Corn and Soybean Production in Conservation Tillage Systems
Authors: Blumenschein Theodore G. , Nelson Kelly A. , Motavalli Peter P.
Published: June 2018

Agricultural soils utilized for corn (Zea mays L.) and soybean (Glycine max [L.] Merr.) production in the Midwestern U.S. are often managed to have adequate surface soil pH for crop growth, but the presence of acidic subsoils may limit crop production. Subsoil acidity may inhibit root growth, leading to decreased drought tolerance and grain yields. Application of aglime can increase soil pH, improve soil structure, and provide calcium and magnesium to the soil, but surface amendments that often occur in no-till systems rarely affect the subsoil, resulting in potential chemical and physical barriers to root growth. The objective of this study was to determine the effects of surface and a new deep vertical lime placement practice, at three application rates, on corn and soybean plant growth and yields in a conservation tillage system. Field trials were conducted from 2012 to 2016 in Northeast Missouri on a poorly-drained claypan soil with treatments of lime (0, 3.4, and 6.7 Mg ha−1) broadcast on the soil surface or applied as a deep vertical band to a depth of 51 cm. When precipitation was below average, compared to control plots, deep vertical placed lime at 6.7 Mg ha−1 significantly raised corn yields by 1.3 Mg ha−1 four years after treatment. In years with adequate precipitation, no significant increases in corn yield were observed with deep lime placement treatments compared to the control. Lime treatments had a greater effect on corn yield than soybean. Deep vertical placement of lime resulted in no significant increase in soybean yield compared to the controls for all trials. Longer observation time may be needed to fully evaluate the effects of these lime placement treatments.

Published: June 2018

Despite being undomesticated, African Grey Parrots (Psittacus erithacus) are commonly found in captivity, in zoos or as pets. Captivity can be an ongoing stressor. Non-invasive glucocorticoid metabolites (GCM) measurements from bird droppings are of interest for assessing stress but require careful evaluation in each newly studied species. This study describes the assessment of such methods for Psittacus erithacus to provide tools for evaluating stress and monitoring welfare. We evaluated 12 method combinations of GCM extraction and enzyme immunoassay (EIA) from a pool of African Grey Parrot droppings, through the validation of several analytical parameters. Then, Heterophil: Lymphocyte Ratios (HLR), another reliable stress marker, were determined and correlated to individual dropping GCM concentrations for 29 birds to determine whether the method is biologically relevant. We found that the best procedure to measure GCM in African Grey Parrot droppings is a combination of 60% methanol extraction measured using a Corticosterone EIA kit (Cayman Chemical Company) from fresh or dry droppings. The establishment of a significant correlation (Pearson coefficient correlation = 0.48; p = 0.0082) between HLR and GCM in the studied population confirmed the method biological relevance. This method can thus be applied to assess stress in Psittacus erithacus and support welfare monitoring in zoo populations.

The present work describes the study of micro (H-ZSM-5) and mesoporous (AL-MCM-41) structures, aiming at their application in the production of renewable fuels through the thermos-catalytic pyrolysis process both were synthesized hydrothermally and characterized by X-ray diffraction, thermal analysis, infrared spectroscopy, nitrogen adsorption, and surface acidity. The catalytic effect of the materials mentioned, as well as their mechanical mixtures in the proportions of H-ZSM-5 (75% wt) and AL-MCM-41 (25% wt); H-ZSM-5 (50% wt) and AL-MCM-41 (50% wt); H-ZSM-5 (25% wt) and AL-MCM-41 (75% wt) were used in the thermal and thermo-catalytic pyrolysis of sunflower oil. The products obtained in the presence of H-ZSM-5 (25% wt) and AL-MCM-41(75% wt) showed selectivity for the conversion of hydrocarbons between C11 and C16, which is near that of the petroleum-derived kerosene and diesel (>C16). On the other hand, the H-ZSM-5 (75% wt) and AL-MCM-41 (25% wt) material, in which the majoritarian catalyst is the microporous, with active sites and a higher surface acidity, indicates selectivity for light hydrocarbons (C5-C10), in the range of gasoline obtained by the conversion of mineral oil. The presence of catalysts (AL-MCM-41and H-ZSM-5) favors the deoxygenation of the pyrolysis products of sunflower oil by decarbonylation reaction.

Current State of Pediatric Heart Failure
Authors: Das Bibhuti B.
Published: June 2018

Pediatric heart failure (HF) represents an important cause of morbidity and mortality in childhood. There is an overlapping relationship of HF, congenital heart disease, and cardiomyopathy. The goal of treatment of HF in children is to maintain stability, prevent progression, and provide a reasonable milieu to allow somatic growth and optimal development. Current management and therapy for HF in children are extrapolated from treatment approaches in adults. There are significant barriers in applying adult data to children because of developmental factors, age variation from birth to adolescence, and differences in the genetic expression profile and β-adrenergic signaling. At the same time, there are significant challenges in performing well-designed drug trials in children with HF because of heterogeneity of diagnoses identifying a clinically relevant outcome with a high event rate, and a difficulty in achieving sufficient enrollment. A judicious balance between extrapolation from adult HF guidelines and the development of child-specific data on treatment represent a wise approach to optimize pediatric HF management. This approach is helpful as reflected by the increasing role of ventricular assist devices in the management of advanced HF in children.

The aim of this study was to investigate whether atmospheric-pressure plasma (APP) or ultraviolet (UV) irradiation could alter the hydrophilicity of a computer-aided design/computer-aided manufacturing (CAD/CAM) glass ceramic surface, and thereby enhance the repair bond strength between the ceramic and a resin composite. Forty-eight leucite-reinforced glass ceramic discs were treated with 40% phosphoric acid and randomly assigned into one of six groups: Group 1, control; Group 2, treated with a mixture of Clearfil SE Bond primer (SEP) and Clearfil Porcelain Bond Activator (PBA); Group 3, subjected to APP irradiation for 10 s; Group 4, subjected to UV irradiation for 60 min; Group 5, APP irradiation followed by SEP/PBA; and Group 6, UV irradiation followed by SEP/PBA. After treatment, discs were bonded with resin composite using Clearfil SE Bond and stored in water at 37 °C for 1 week. We then tested how these treatments affected the microtensile bond strength (µTBS) and measured changes in the water contact angle (CA). Samples from Group 2 showed the highest µTBS (44.3 ± 6.0 MPa) and CA (33.8 ± 2.3°), with no significant differences measured between Groups 1, 3, and 4 (p < 0.05). Furthermore, the additional treatments of APP or UV before SEP/PBA had no effect (Group 5, p = 0.229) or a reduced effect (Group 6, p = 0.006), respectively, on µTBS. Overall, APP or UV irradiation before SEP/PBA treatment did not enhance the repair bond strength.

We study linear-quadratic stochastic optimal control problems with bilinear state dependence where the underlying stochastic differential equation (SDE) has multiscale features. We show that, in the same way in which the underlying dynamics can be well approximated by a reduced-order dynamics in the scale separation limit (using classical homogenization results), the associated optimal expected cost converges to an effective optimal cost in the scale separation limit. This entails that we can approximate the stochastic optimal control for the whole system by a reduced-order stochastic optimal control, which is easier to compute because of the lower dimensionality of the problem. The approach uses an equivalent formulation of the Hamilton-Jacobi-Bellman (HJB) equation, in terms of forward-backward SDEs (FBSDEs). We exploit the efficient solvability of FBSDEs via a least squares Monte Carlo algorithm and show its applicability by a suitable numerical example.

Published: June 2018

In this work, the crystallization behaviors, such as degree of crystallinity and crystalline thickness of poly(ε-caprolactone) (PCL) matrix with the incorporation of graphene oxide (GO) and their evolution with time were examined in order to better understand the influences of residual groups of GO on the semi-crystalline polyester. The results showed that the residual strong oxidizing debris on the GO surface could induce the degradation of amorphous parts in PCL matrix. Moreover, the increasing degree of crystallinity and almost constant crystalline thickness implies that oxidative degradation cannot degrade the crystal structure of PCL matrix.
Concentration of Immunoglobulins in Microfiltration Permeates of Skim Milk: Impact of Transmembrane Pressure and Temperature on the IgG Transmission Using Different Ceramic Membrane Types and Pore Sizes

Published: June 2018

The use of bioactive bovine milk immunoglobulins (Ig) has been found to be an alternative treatment for certain human gastrointestinal diseases. Some methodologies have been developed with bovine colostrum. These are considered in laboratory scale and are bound to high cost and limited availability of the raw material. The main challenge remains in obtaining high amounts of active IgG from an available source as mature cow milk by the means of industrial processes. Microfiltration (MF) was chosen as a process variant, which enables a gentle and effective concentration of the Ig fractions (ca. 0.06% in raw milk) while reducing casein and lactose at the same time. Different microfiltration membranes (ceramic standard and gradient), pore sizes (0.14–0.8 µm), transmembrane pressures (0.5–2.5 bar), and temperatures (10, 50 °C) were investigated. The transmission of immunoglobulin G (IgG) and casein during the filtration of raw skim milk (<0.1% fat) was evaluated during batch filtration using a single channel pilot plant. The transmission levels of IgG (~160 kDa) were measured to be at the same level as the reference major whey protein β-Lg (~18 kDa) at all evaluated pore sizes and process parameters despite the large difference in molecular mass of both fractions. Ceramic gradient membranes with a pore sizes of 0.14 µm showed IgG-transmission rates between 45% to 65% while reducing the casein fraction below 1% in the permeates. Contrary to the expectations, a lower pore size of 0.14 µm yielded fluxes up to 35% higher than 0.2 µm MF membranes. It was found that low transmembrane pressures benefit the Ig transmission. Upscaling the presented results to a continuous MF membrane process offers new possibilities for the production of immunoglobulin enriched supplements with well-known processing equipment for large scale milk protein fractionation.

Epilepsy is a neuronal disease that affects up to 70 million people worldwide. The development of effective therapies to combat childhood epilepsy requires early biomarkers. Here, we performed a whole-genome microarray analysis in blood cells to identify genes differentially expressed between epileptic and epileptic valproic acid (VPA)-treated children versus normal children to obtain information about the gene expression to help us to understand genetic aspects of this disease. We found that the most significant differentially expressed genes were related to the transcriptional factor cAMP-response element binding protein (CREB) that is overexpressed in children with epilepsy compared with normal children, and 6 and 12 months of VPA treatment reversed several of these changes. Interestingly, leukocyte-associated immunoglobulin-like receptor 1 (LAIR1), a type I transmembrane glycoprotein that binds collagen proteins and contains CREB binding sites, was one of the more up-regulated genes in epileptic patients, and treatment with VPA strongly reversed its up-regulation. CREB up-regulates genes related to epilepsy; here, we suggest that LAIR1 could activate CREB, and together, they trigger epilepsy. After VPA treatment, LAIR1 repressed genes by disrupting the functional LAIR1–CREB complex, resulting in successful treatment. A functional microarray analysis offers new information that could open novel avenues of research in biomarker discovery, which may be useful for the early identification of children with a predisposition to epilepsy.

An anthropogenic activity is one of the most severe environmental causes for groundwater contamination in the urban area. Groundwater thought to be one of the principal sources of water supply in Halabja Saidsadiq Basin, and therefore its vulnerability evaluation to define areas that are more vulnerable to pollution is incredibly vital. The objectives of this paper are to reveal weight modified of DRASTIC model based on the Analytical Hierarchical Process to estimate the proportional likelihood of groundwater resources pollution. Tritium isotopes analysis was chosen and applied as a pollution marker to confirm the result of this adjustment. Based on this modification, vulnerability classes that were achieved for the studied basin were alienated into five classes, including very low, low, medium, high, and very high, with vulnerability index value of (<100, >100–125, >125–150, >150–200, and >200), respectively.

This paper reviews stable isotopic data concerning spring water in Greece in addition to new measurements (59); their spatial variations are investigated in order to provide basic information and identify the locally significant parameters that affect stable isotopic distributions. The area of interest was partitioned into eight sections according to geographical location and climatic characteristics. Local spring water lines (LSWLs) are more or less consistent throughout the country. High-resolution isoscape maps of spring freshwater (Cl− < 200 ppm; and T < 25 °C) for both δ18O and δ2H were generated, revealing several interesting features such as the effect of Pindos ridge, a strong climatic signal in southern Greece and indications of seawater intrusion in flat coastal areas.

With the wide deployment of the video sensor network and the rapid development of video spatialization technology, the large volume of complex GeoVideo data necessitates improvements in the application efficiency of the GeoVideo database and GeoVideo surveillance system. Traditional storage management approaches focus on the optimization of access to the GeoVideo stream. However, they suffer from poor management of the diverse movement processes contained within it; for example, they cannot support associative queries or comprehensive analysis of multi-type GeoVideo data in complex geographic environments. This paper takes physical movement process in GeoVideo as a new type of object and carries out an objectified organization of the heterogeneous GeoVideo data around it (including the video stream, spatial references, interpretations of the video data, and the overall scene) in a Not only SQL-Structured Query Language (NoSQL-SQL) hybrid GeoVideo database. This paper systematically explores the hybrid spatiotemporal indexes and multi-modal retrieval methods around movement processes, which enrich the query modes of the GeoVideo data. A prototype implementation and experimental analysis are presented to prove the feasibility and effectiveness of this organization and retrieval approach.

We report on the realisation of a cyclotron trap assisted positron tungsten moderator for the conversion of positrons with a broad keV–few MeV energy spectrum to a mono-energetic eV beam with an efficiency of 1.8(2)% defined as the ratio of the slow positrons divided by the β+ activity of the radioactive source. This is an improvement of almost two orders of magnitude compared to the state of the art of tungsten moderators. The simulation validated with this measurement suggests that, using an optimised setup, even higher efficiencies are achievable. A novel method for the production of 48V high-activity thin foil positron sources based on a solid target station at a medical cyclotron was developed. This is an improvement of more than one order of magnitude with respect to standard methods.
