Glacier Changes and Their Linkage to the Climate-Topographic Context in the Borohoro Mountains, Tian Shan 1977–2018
Authors: Li Yanan
Published: May 2020

Against the backdrop of climate change and socio-ecological sustainability, studying glacier changes provides essential knowledge to the basic water needs and security for regions and populations under such threats, such as Central Asia. Little attention has focused on glaciers in the northern periphery of the Chinese Tian Shan. This study aims to map a recent glacier inventory and examine the glacier area shrinkage and surface elevation change for the central massif of the Borohoro Mountains in the past 41 years. Using declassified Hexagon images (1977), Landsat 5 TM (1994 and 2007), Sentinel 2A (2018) and altimetry data from the Ice, Cloud and Land Elevation Satellite (ICESat) over 2003–2009 with the 30-m Shuttle Radar Topography Mission (SRTM) digital elevation model, multi-temporal glacier fluctuations and the influence of topographic and climatic factors were investigated. Results show that the glacier area decreased from 287.5 ± 8.2 km2 in 1977 to 215.8 ± 4.1 km2 in 2018, at a rate of 0.61 ± 0.01% year−1. Glacier disintegration has led to a gradual increase in the number of glaciers and reached 224 glaciers in 2018. The shrinkage was at the highest rate during the 1994–2007 period and the smallest during 1977–1994. Glacier size, hypsometry, and median, maximum, and range of elevation are the most significantly correlated parameters with the relative area change. The surface elevation changes from two of the largest glaciers revealed a stronger thinning on the southern slope compared to the northern slope. These observations of glacier loss are primarily driven by the marked warming trend since the 1970s and confirmed with the overall pattern of glacier retreat in the Tian Shan from previous studies.

Drought is among the most common natural disasters in North China. In order to monitor the drought of the typically arid areas in North China, this study proposes an innovative multi-source remote sensing drought index called the improved Temperature–Vegetation–Soil Moisture Dryness Index (iTVMDI), which is based on passive microwave remote sensing data from the FengYun (FY)3B-Microwave Radiation Imager (MWRI) and optical and infrared data from the Moderate Resolution Imaging Spectroradiometer (MODIS), and takes the Shandong Province of China as the research area. The iTVMDI integrated the advantages of microwave and optical remote sensing data to improve the original Temperature–Vegetation–Soil Moisture Dryness Index (TVMDI) model, and was constructed based on the Modified Soil-Adjusted Vegetation Index (MSAVI), land surface temperature (LST), and downscaled soil moisture (SM) as the three-dimensional axes. The global land data assimilation system (GLDAS) SM, meteorological data and surface water were used to evaluate and verify the monitoring results. The results showed that iTVMDI had a higher negative correlation with GLDAS SM (R = −0.73) than TVMDI (R = −0.55). Additionally, the iTVMDI was well correlated with both precipitation and surface water, with mean correlation coefficients (R) of 0.65 and 0.81, respectively. Overall, the accuracy of drought estimation can be significantly improved by using multi-source satellite data to measure the required surface variables, and the iTVMDI is an effective method for monitoring the spatial and temporal variations of drought.

Authors: Homaeigohar Shahin
Published: May 2020

The studies introduced in this special issue aim to provide a state-of-the-art vision for nanomaterials-based technology that could profit the water treatment industry. Given the expanding crisis of water shortages across the world, this perspective is invaluable and of paramount importance. No doubt, as the environmental challenges are going to be more complicated and to extend to as-yet unconsidered areas, we need to upgrade our facilities and knowledge to address them properly. Nanomaterials are indeed promising building blocks for such advanced technologies that enable them to purify water streams from complex pollutants in an energy, cost and time-effective manner. The focus of the (review and original research) articles collected in this issue is on various kinds of nanomaterials made of carbon, polymer, metal, and metal oxides (magnetic and photocatalyst), that are employed for adsorption and photodegradation of heavy metals and organic pollutants, respectively. Here, I briefly review the insights given in these precious studies and suggest new directions for future research in this field.
UPDATING THE PRESTIGE OF THE CIVIL SERVICE IN THE REFORM PROCESS
Authors: Karkovska Veronika
Published: May 2020

The prestige of the civil service affects the quality of attracting resources to the public administration, and the civil service is considered as part of the public administration connected with the realization of the goals, tasks and functions of the state. The study of the factors of prestige and the attempt to formulate its model are necessary to manage the process of raising the prestige of socially important spheres of life, one of which is the protection of national interests. The article identifies and analyzes that influence the formation of the prestige of the civil service of Ukraine and leading countries. They are based on the use of official position not in the interests of society: protectionism, mutual services, use of state property for personal purposes, as well as bribes, kickbacks and other illegal mechanisms of "transformation of power into money". Also, criteria have been selected to take into account the prestige, which are a result of the efficiency of public administration and the macroeconomic environment, because they reflect the possibilities and freedom of realization of activity. Updating the prestige of the civil service is a prerequisite for successful European integration and good and efficient public administration that meets the requirements of modern times and European standards and principles of good governance. The  detail analyzes the main factors influencing the prestige of the civil service. After evaluating all possible factors, we can distinguish those that most accurately and accurately reflect the results of the question under study. Measures justified to increase the level of prestige of the civil service.The effectiveness of the reform of the Ukrainian civil service must be accompanied by the creation of a professional, politically impartial, stable, highly efficient, authoritative and prestigious civil service capable of meeting the challenges of today and providing quality administrative services that meet European standards.
СТРАТЕГІЧНІ ЗАВДАННЯ РОЗВИТКУ ІНСТИТУТУ ПУБЛІЧНИХ ЗАКУПІВЕЛЬ
Authors: Tymofieiev Serhij , Kolesnichenko Oksana
Published: May 2020

В даній статті автор аналізує сучасний стан сфери публічних закупівель в Україні, вказуючи, що останнім часом науковці приділяють даній сфері все більшу увагу, досліджує досвід проведення публічних закупівель в провідних зарубіжних країнах, який можна імплементувати в Україні. Вказує, що основні поняття діючої моделі контрактної системи залишаються поза загальнообов'язкових і формально певних категорій в умовах нестабільності законодавчого регулювання. Формулює задачу систематизації понятійного і термінологічного апарату для виділення і розмежування окремих сегментів ринку закупівель. Виконаний огляд міжнародних і національних документів дозволяє з певною мірою умовності систематизувати інформацію про масштаби регулювання закупівель в розглянутих країнах. На сучасному етапі розвитку світової економіки спостерігається загальна тенденція до посилення ролі контрактних систем управління громадськими закупівлями. При цьому в країнах з розвиненою конкурентною економікою контрактні системи мають широкий функціонал не тільки в сфері громадських закупівель. У відповідній директиві Європейського союзу (ЄС) також використовується термін public procurement (публічні закупівлі), під яким слід розуміти закупівлі влади будь-якого рівня і юридичних осіб, які регулюються публічним правом. Пропонується розділити систему регулювання закупівель на три самостійних сегмента: закупівлі держави; закупівлі державних підприємств; закупівлі комунальних та /або інфраструктурних підприємств. Це дозволить, з одного боку, розширити межі контрактної системи а з іншого – розробити більш сегментовані і «адресні» механізми регулювання закупівель. Максимальний масштаб регулювання закупівель спостерігається в директивах ЄС і правових актах розглянутих європейських країн, де предметом регулювання виступають, в тому числі, закупівлі структур, регульованих публічним правом. Доходить висновку, що розглянутий стратегічний підхід до формування контрактної моделі передбачає розробку і реалізацію нової закупівельної політики і системи нормативного правового регулювання в сфері суспільних закупівель.
ДЕРЖАВНО-ПРИВАТНЕ ПАРТНЕРСТВО ЯК ВАЖЛИВИЙ ІНСТРУМЕНТ ЗАБЕЗПЕЧЕННЯ СТАЛОГО РОЗВИТКУ ТЕРИТОРІЙ

Published: May 2020

У статті зазначено, щоз 2015 року перед міжнародною спільнотою постали нові амбітні завдання щодо досягнення цілей сталого розвитку, визначених схваленою на черговому саміті Організації Об’єднаних Націй Стратегією “Перетворення нашого світу: Порядок денний у сфері сталого розвитку до 2030 року”. Майже всі вони передбачають необхідність створення або модернізації економічної та соціальної інфраструктури в країнах, які розвиваються, що  потребує значних фінансових ресурсів. Однак, бюджети таких країн не можуть покрити наявні фінансові потреби.Тому, одним із найважливіших завдань нової глобальної стратегії сталого розвитку було визнано створення умов для залучення фінансових ресурсів приватного сектору для розбудови інфраструктури на засадах публічно-приватного партнерства (ППП). Зауважено, що основне завдання органів публічної влади сьогодні полягає у формуванні сприятливого середовища для ведення бізнесу, ефективного використання ресурсного потенціалу, визначенні пріоритетів в соціальних, економічних та екологічних процесах і перспектив розвитку територіальної громади з врахуванням її потреб й інтересів.
Акцентовано увагу на тому, що у світі дедалі більше стає популярним державно-приватне партнерство у формі концесії, оскільки саме така форма взаємодії між приватним та публічним партнером створює суттєву додану вартість для обох сторін. Одне з найбільших досягнень концесій – завдяки їй вирішуються державні завдання силами приватного капіталу, який вважається економічно ефективнішим державного. При цьому, приватний партнер отримує довгостроковий фінансовий інтерес, який дозволяє йому забезпечити максимальну ефективність вирішення поставленого державою чи муніципалітетом завдання. Обґрунтовано доцільність застосування державно-приватного партнерства при формуванні інструменту забезпечення сталого розвитку територій як важливого інструменту забезпечення сталого розвитку територій.

Palynology and depositional history of the Paleocene? Thyra Ø Formation, Wandel Sea Basin, eastern North Greenland
Authors: Lyck Jens M. , Stemmerik Lars
Published: May 2020

The Thyra Ø Formation in eastern North Greenland has been dated as Late Paleocene to possibly earliest Eocene based on its content of palynomorphs. The palynomorph assemblage is dominated by long ranging taxa and reworked Upper Cretaceous species. The Late Paleocene age of the formation is based on the occurrence of Cerodinium speciosum and Spinidinium pilatum. However, the presence of Cerodinium markovae, Spinidinium sagittula, and ?Ilexpollenites sp. suggests that the formation may range into the earliest Eocene.

The summer of 2000 was exciting for everyone interested in the petroleum geology and exploration of West Greenland. The first offshore well in more than 20 years was drilled by the Statoil group in the Fylla licence area, and seismic acquisition activity offshore West Greenland was more intense than previous years with four new surveys being carried out (Fig. 1).

Expectations were high when drilling of the Qulleq-1 well was initiated in July 2000, not only with the licensees and the authorities, but also with the public. The well was classified as highly confidential, but nevertheless all information available was closely followed by the press, especially in Greenland and Denmark, but also internationally (see Ghexis 2000). Disappointment was equally high when the press release in September 2000 reported that the well was dry. Since that time much technical work has been carried out by Statoil and its consultants (Pegrum et al. 2001) and by the Geological Survey of Denmark and Greenland (GEUS), and a more balanced view of the positive and negative surprises from the well can now be presented.
Thalcusite from Nakkaalaaq, the Ilímaussaq alkaline complex, South Greenland
Authors: Karup-Møller Sven , Makovicky Emil
Published: May 2020

Thalcusite from a new locality in the Ilímaussaq complex, the Nakkaalaaq mountain, occurs in a coarse ussingite–aegirine vein and is associated with sphalerite and cuprostibite. The empirical composition is Tl1.89K0.08Cu2.86Fe1.34S4.00. Secondary tenorite–Sb oxide aggregates are developed along cleavages. Tarnish products are essentially pure Cu+ sulphide. All three layered thallium sulphides from the Ilímaussaq complex, thalcusite, chalcothallite and rohaite, contain K substituting for Tl. Varieties with K > Tl were not found in the massif.

Published: May 2020

At Ilímaussaq hiortdahlite has only been known from a dyke located immediately to the south-east of the complex. This mineral has now been found in a pegmatite horizon in the sodalite-rich rock naujaite of the complex. It appears to be earlier than eudialyte and is regarded as having been formed at low alkalinity at an early stage of naujaite formation. The optical and X-ray parameters are identical to the data for hiortdahlite from Kipawa, Quebec, and indicate that the Ilímaussaq mineral is type II hiortdahlite. Minerals from the Iles de Los, Guinea, and the Tamazeght complex, Morocco, have been examined by optical and X-ray methods and chemical analysis, and are shown also to be hiortdahlite II.
The Areopagus Speech and Contextualization: Some Hermeneutical and Exegetical Considerations
Authors: Pardigon Flavien

The Areopagus Speech Is Commonly Seen As A Model Of Missionary Contextualization, An Exemplary Translation Of The Gospel Into The Language And Concepts Of Paul’s Athenian Audience. This Article Evaluates This Line Of Interpretation Using The Hermeneutical Concept Of “framing” That Is At The Heart Of Contemporary Linguistics, Narratology, Translation Theory, And Evangelical Contextualization Models. Looking Especially At The Work Of Colin Chapman And Kevin Higgins, Two Influential Missiologists, And Considering Seven Key Exegetical Cruxes, It Shows That Their Type Of Interpretation Fails To Read The Speech Contextually Because It Is Not Attentive To The Way Paul And Luke Frame The Text.

After A Brief Overview Of The CAMEL Method And Its Contexts (twentieth-century Missions, The International Mission Board, And The Bangladeshi Context), I Will Discuss Four Themes Common To CAMEL And IM. We Will See That CAMEL And IM Share Similar Assumptions Yet With Different Outworkings. Both Seem To Share The Sentiment Of The Catholic Louis Massignon, Chief Architect Of Vatican II’s Approach To Non-Christian Religions: “Rather Than Destroy Islam, Might It Then Not Be Better To Expand It? … If A Moslem Followed His Soul’s Promptings To The End, He Would Come To Christ.” KEYWORDS: Camel Method, Insider Movement, mission, Islam, Bangladesh
Missiological Implications of Conscience in Present-Day Roman Catholicism
Authors: Karr Reid
Published: May 2020

During Jorge Mario Bergoglio’s Papacy, The Theology Of Conscience Has Taken On A Significant Role. A Developed Theology Of Conscience Emerged During The Second Vatican Council, Most Notably With Gaudium Et Spes, And Later Developed As Essential In Moral Theology. Francis Is The First Pope To Fully Embody Vatican II Teachings, In Particular In His Incorporation Of The Conscience Into Theology And Practice. During The First Months Of His Papacy, He Made It Clear That Conscience Is Crucial To His Theology And, In A Letter Exchange With A Prominent Italian Journalist, He Underscored Obedience To One’s Conscience As The Key To Receiving Forgiveness Of Sins. This Development Has Tremendous Theological And Missiological Implications For The Roman Catholic Church.

Cults and Conscience: Apologetics and the Reconfigured Conscience of Cult Members
Authors: STOKER H. G. (HENK)
Published: May 2020

While Our Creator Made The Human Conscience An Intrinsic Part Of Us To Enable Us To Fulfill Our Calling Morally And Responsibly, Cults Use People’s Consciences To Control Them—even To Do Things That They Would Have Previously Considered As Wrong. The Conscience Goes Against The Immediate Human Impulse For Self-interest And Is Independent Of The Individual’s Will Because God Created It To Go Against That Person’s Desire. A Guilty Conscience Can Thus Be Abused As A Very Effective Means Of Control. While The So-called Christian Cults Make Their Members Willfully Obedient Through Reconfiguring Their Consciences, Christian Apologists Should Find Ways To Address The Content Of Cult Members’ Consciences To Bring Them Back To A Truly Biblical Understanding.

Ti underlayer effect on the ordering of CoPt in (Co/Pt)4 multilayer thin films on Si/SiO2 substrates
Authors: Toyama Ryo , Kawachi Shiro , Yamaura Jun-ichi , Murakami Youichi , Hosono Hideo , Majima Yutaka
Published: May 2020

L12-ordered CoPt3 and L10-ordered CoPt are formed in electron-beam-deposited (Co/Pt)4 multilayer thin films with and without a Ti underlayer, respectively, on Si/SiO2 substrates by rapid thermal annealing. The crystal structures, magnetic properties, and surface morphologies of the films are investigated by grazing incidence X-ray diffraction (GI-XRD), vibrating sample magnetometer (VSM), and scanning electron microscope (SEM), respectively. In the film without a Ti underlayer, L10-ordered CoPt with an isolated round grain structure is confirmed, showing an in-plane coercivity of 2.7 kOe. In contrast, in the film with a Ti underlayer, L12-ordered CoPt3 is confirmed together with Co-rich A1-disordered CoPt, showing an in-plane coercivity of 500 Oe, which exhibits an angular-outlined continuous film structure. The three sets of experimental results from GI-XRD, VSM, and SEM coincide well with each other.

Authors: Paul Femi Fashagba  , Abiola Abosede Solanke
Published: May 2020

Previous studies have examined the effects of International Financial Reporting Standards (IFRS) adoption on earnings management. However, these studies focused attention on the general implications of IFRS adoption on earnings management with no specific focus on the links between performance appraisal and earnings management in the pre and post IFRS era. The objective of the study is to examine the relationship between performance appraisal and earnings management in Pre and Post IFRS period. The dependent variable in the study is earnings management proxy by earnings per share. The independent variable is performance appraisal measured by profitability ratio, liquidity ratio, and debt ratio. Data were extracted from the records of a consumer good company in Nigeria. The multiple regression analysis was applied. Results revealed that in the pre IFRS period in Nigeria, performance appraisal had significant positive effect on earnings management, while it had significant negative effect in the post IFRS period. It is important that company’s management adhere strictly to the provisions of the IFRS guidelines.

PECULIARITIES OF MODELING IN AGRICULTURAL PRODUCTION WITH RISK ACCOUNTING
Authors: USHKALENKO Irina
Published: May 2020

The causes of the risk inherent in any field of human activity, in particular for agricultural production are considered. AIC, in contrast to other branches of production, has a very important specific reason for the appearance of risk - weather conditions. Weather conditions are one of the main factors of the degree of uncertainty for agricultural production. When developing the organization of production of the agricultural sector, the natural and climatic conditions must be taken into account. In the agroindustrial complex, weather risk is most important and the main task of modeling and optimizing agricultural production is the development of ways of taking into account and reducing the weather risk. Economic result, which is an indicator effectiveness production in agriculture economy, depends independent characteristics of weather conditions. The problem of weather economic sustainability and risk far exceeds the problem of productive stability, because not only all agricultural industries, but also the national economy of the country as a whole are closely related to agricultural production. The instability of agricultural production significantly affects all the integral indicators of the national economy, including the volume of the national product. In the agroindustrial complex, weather risk is most important and the main task of modeling and optimizing agricultural production is the development of ways of taking into account and reducing the weather risk. Economic result, which is an indicator effectiveness production in agriculture economy, depends independent characteristics of weather conditions, that is why it is a random variable. This applies to all regions, all forms of ownership, all types of agricultural activities. Weather conditions can not be managed, but they can be adapted to achieve maximum integral result. To do this, you must select the other projects, strategic and tactical solutions with multiple permissible ones. In principle, there is the ability to manage the characteristics of weather resistance economic efficiency. In this case, we must try to obtain the maximum economic effect not only in a separate weather situation, but also during the long term, so that the effectiveness of the production is as possible as possible in relation to the accidental weather conditions in the given climate zone.

Authors: Majidova Ya. N. , Khalilova A. E.
Published: May 2020

The aim of the study is to assess the impact of cytoflavin inclusion on the dynamics of indicators of arterial ischemic stroke of various etiologies in children. Dynamic monitoring of 47 children with arterial ischemic stroke was carried out, 30 of them received cytoflavin via a slow intravenous drip infusion with 5 ml of the drug per 100 ml of saline for 10 days. Subsequently, after 2, 6 months and one year patients received the tablet form of the drug 2 times a day in the 1st year after the disease in the complex of rehabilitation measures, in the course of 25 days. The control group consisted of 17 patients who received only basic therapy. In addition to the conventional methods of assessment, transcranial ultrasound dopplerography and electroencephalogram were performed; patients were assessed using the pedNIHSS and PSOM-SNE scales. The severity of seizures was evaluated according to the NHS3 scale. The degree of impaired consciousness was evaluated using Glasgow Coma Scale. It was revealed that the inclusion of cytoflavin in neurometabolic correction in patients with arterial ischemic stroke positively affects the state of cerebral hemodynamics, which is confirmed by transcranial ultrasound dopplerography. The clinical effect of the inclusion of the drug in the treatment regimen is manifested by a decrease in sensorimotor and cognitive impairment, a reduced risk of epileptic activity foci forming as a result of a penumbra zone decrease, which ultimately increases the rehabilitation potential of children with ischemic stroke.

According to epidemiological data, 60% of the world's population suffers fromHelicobacterpyloriinfection. The multicomponent treatment used in 18–20% of cases does not allow eradication ofH.pylori. In addition, reinfection withH.pylorioccurs in the majority of treated patients in 3–5 years. An alternative to antibiotics in the treatment of this infection are seaweed products, in particular extracts and polysaccharides with anti-adhesive, anti-toxic, immunomodulatory, antioxidant, and anti-inflammatory properties. Furthermore, algae polysaccharides have direct bactericidal effect and can destroy biofilms formed byH.pylori. The modern materials presented in the literature review indicate the prospects of developments related to the use of extracts and polysaccharides from seaweed as the basis for drugs, dietary supplements and functional food products for the prevention and treatment ofH.pyloriinfection.
Age dynamics of changes in sexual
behavior and androgen status of male
rats caused by prenatal exposure to low
dose dibutylphthalate
Authors: Reznikov Alexander , Sachynska Olha , Lymareva Аnna
Published: May 2020

The aim of this work was to study the sexual maturation, testicular
hormonal activity and sexual behavior of Wistar male rats, which

were born to mothers treated intragastrically with di-n-butylphtha-
late (DBP) for 15-21 days of their pregnancy, at a daily dose of

100 mg/kg b.w., that do not cause visible developmental morpho-
logical abnormalities. Their sexual behaviour was analyzed via the

proceptive reactions, the latent and refractory periods of time and
number of mounts, intromissions and ejaculations at the presence
of a receptive female. Female sexual behaviour was evaluated by
lordosis responses of orchidectomized and activated with estradiol
and progesterone males in the presence of a normal male. Prenatal
administration of DBP induced an accelerated onset of puberty. In
young mature males (6-month old), it was, unexpectedly (as for
endocrine disruptors), discovered that was featured by hyperactive
central (motivational) and peripheral (copulative and ejaculatory)
components of male sexual behavior and a two-fold increase in
the average levels of plasma testosterone. In 10-month old rats, we
found both homosexual and enhanced lordotic behavior. In aging
animals (18 months), hyperandrogenism had switched to quite the
opposite condition: more than two-fold decrease in the levels of

plasma testosterone, close to statistical significance; and a lessen-
ing of male sexual behavior compared to controls. These findings

show the presence of epigenetic alterations in the programming
of the parts of the brain responsible for sexual differentiation (the

hypermasculinization combined with feminization) and a regula-
tion of testicular hormonopoeisis, as well as premature aging of the

reproductive organs resulting from the prenatal influence of low
dose DBP. Thereby we proposed the original concept of prenatally
determined DBP syndrome.

And, finally, the possible mechanism of these changes in the repro-
ductive system are discussed.

Key words: dibutylphthalate; prenatal effect; sexual behavior; tes-
tosterone; male rats.

Efficacy and Safety of Ombitasvir/Paritaprevir/Ritonavir ± Dasabuvir Regimen in Haemodialysis Patients With Hepatitis C Virus Infection
Authors: Verhaz Antonija , Roganović Tatjana , Pašić Ljiljana , Čuković Olja , Macanović-Kostić Tanja
Published: May 2020

Background: Hepatitis C virus (HCV) infection is common among patients on haemodialysis (HD) therapy and is an important cause of morbidity and mortality. In patients with chronic kidney disease (CKD), the risks for negative outcomes are significantly higher in HCV-infected patients than in those without HCV infection, including progression to cirrhosis, hepatocellular carcinoma and liver-related mortality. Ombitasvir (OBV), paritaprevir (PTV), ritonavir (r), and dasabuvir (DSV) are all hepatically metabolized and, therefore, require no dose adjustment in patients with any degree of renal impairment.
Aims: We studied the safety and efficacy of OBV/PTV/r + DSV in a small group of HCV infected patients on haemodialysis therapy. Methods: Treatment course with ombitasvir/paritaprevir/ritonavir and dasabuvir; (3-DAA regimen of OBV/PTV/r+DSV±RBV) was analysed. Pre-treatment evaluation of HCV infection included HCV RNA, genotype, and liver fibrosis assed by transient fibroelastography (FibroScan). The stage 5 CKD was defined as an eGFR of <15 mL/min/1.73 m2, respectively; those on haemodialysis were considered to have stage 5 CKD or end-stage renal disease (ESRD). Demographic data and concomitant medication were retrieved from patients’ records. The primary endpoint was sustained virologic response at post-treatment week 12 (SVR12). We collected data on on-treatment adverse events (AEs), serious AEs, and laboratory abnormalities. Results: Among 7 treated patients, 6 were male and 1 female, all were infected with genotype 1 (5 GT1b, 2 GT1a). Patient had compensated liver cirrhosis and six patients did not have liver cirrhosis, none were liver transplant recipients. All of seven patients completed 12 weeks of treatment and achieved SVR12. Concomitant medication had to be modified with the treatment initiation in 5 out of 7 patients. One of the patients presented with a significant decrease in haemoglobin level, white blood cell and platelet count during the treatment period. The most frequent adverse events were nausea, diarrhoea. Adverse events were primarily mild, and no patient discontinued treatment due to an AE. Conclusions: Treatment with OBV/PTV/r +DSV ± RBV was well-tolerated and resulted in high rates of SVR12 (100%) for patients with HCV GT1b/1a on haemodialysis.

As tick-borne disease incidence and distribution is increasing worldwide, there is a true need for better understanding of the distributional ecology of their vectors. The aim of this study was to determine the diversity of hard ticks fauna (Acari: Ixodidae) and their seasonal dynamics in different habitats at three urban recreational sites in Croatia’s capital, the City of Zagreb, known as the natural foci of Lyme borreliosis and tick borne encephalitis. Within a three-year period (2016 - 2018), the only species detected was Ixodes ricinus Linnaeus, 1758. Using flag dragging method 506 ticks were sampled; 273 (54%) in their nymphal stage, 166 (33%) as larvae and 64 (13%) as adults. The highest abundance of ticks was recorded at forest habitat. Seasonal activity showed their peaks at midspring and midsummer. Continuous monitoring of hard tick population in urban areas should and could become a standard method of tick-borne diseases prevention.
Income Inequality of Oil Palm Plasma Farmers in South Sumatra, Indonesia
Authors:   Research Center for Population- The Indonesian Institute of Sciences, Ngadi
Published: May 2020

One of the critical policies to encourage oil palm development in Indonesia is the Nucleus Estate Smallholders Project. This project involves engaging farmer organizations in operating and managing oil palm plantations. However, there are gaps in the organizational performance of plasma farmer cooperatives, which consequently affect oil palm productivity and farmers’ welfare. This paper analyzes the income gaps among oil palm plasma farmers who are associated with state and private companies in Musi Banyuasin regency, South Sumatra, Indonesia. The results of the analysis show that the income of plasma farmers from the private company is higher than that of the state company plasma farmers. The type of nucleus company has a significant effect on the plasma farm households’ income due to the differences in the organizational performance of the private- and state-sponsored cooperatives and the differences in the nucleus-plasma farmer relations. The cooperative that operates in a private company performs well, whereas the cooperative in a state company has ceased its operations. This research also found out that the number of household working members, income share from oil palm production, and land area have significant effects on the income of plasma farm households.

Published: May 2020

Since the outbreak of coronavirus disease- 19 (COVID-19) pandemic, geriatric population has been the most affected due to the peculiarities of the disease in terms of contagiousness and severity. Major changes have been implemented in healthcare structures and facilities worldwide in order to accomplish the necessity to host and isolate infected patients. Simultaneously, many critical issues have emerged concerning medical and nursing assistance to elderly patients, due to the new arrangement of wards and innovative work tools. Acute Geriatric Units dedicated to COVID-19 have been asked to put giant efforts in adapting to new care models in mobility, communication, feeding, basic assistance and caregivers’ involvement. The purpose of this dissertation is to highlight the role of Geriatricians as proactive contributors of new approaches to elderly patients in times of COVID-19, in order to develop a further-thinking working methodology.

Точные константы в двусторонней оценке С. А. Теляковского суммы
ряда по синусам с выпуклой последовательностью коэффициентов
Authors: Solodov Aleksei Petrovich
Published: May 2020

Известно, что сумма ряда по синусам
$g(\mathbf b,x)=\sum_{k=1}^\infty b_k\sin kx$, коэффициенты
которого образуют выпуклую последовательность $\mathbf b$,
положительна на интервале $(0,\pi)$. Для оценки ее значений
в окрестности нуля C. А. Теляковский использовал
кусочно-непрерывную функцию
$$
\sigma(\mathbf b,x)=\frac1{m(x)}\sum_{k=1}^{m(x)-1}k^2(b_k-b_{k+1}),\qquad
m(x)=[\frac\pi x].
$$
Он показал, что
разность $g(\mathbf b,x)-(b_{m(x)}/2)\operatorname{ctg}(x/2)$ в некоторой окрестности нуля
допускает
двустороннюю оценку через функцию $\sigma(\mathbf b,x)$
с абсолютными постоянными. В работе найдены точные значения
этих постоянных на классе выпуклых последовательностей $\mathbf b$.

O presente estudo teve como objetivo investigar a biologia populacional de Minuca mordax no Rio Igaraçu, Parnaíba, PI, analisando a distribuição de frequência em classes de tamanho, período reprodutivo, crescimento relativo, maturidade sexual morfológica, razão sexual e heteroquelia. Os animais foram coletados manualmente de forma aleatória por duas pessoas durante 1 hora, nos meses representativos da estação seca (setembro a novembro) e chuvosa (abril a junho). Em laboratório os caranguejos foram identificados, separados quanto ao sexo e mensurados. Um total de 610 exemplares foi capturado, sendo 453 machos e 157 fêmeas. O tamanho médio da largura de carapaça (LC) diferiu significativamente (p<0,05) entre machos (17,21 ± 3,68 mm) e fêmeas (15,06 ± 3,18 mm). A distribuição dos caranguejos em classes de tamanho foi unimodal para ambos os sexos. A maturidade sexual morfológica obtida para os machos foi de 12,42 mm de LC e para as fêmeas foi de 10,05 mm de LC. A razão sexual para a população foi de 1:0,35 (macho:fêmea), sendo verificada diferença significativa da proporção esperada de 1:1. A heteroquelia foi verificada apenas nos machos da espécie (224 destros e 229 sinistros). Posteriormente, outras observações in loco foram realizadas mensalmente, de fevereiro/2011 a janeiro/2012 para observação de fêmeas ovígeras e determinação do período reprodutivo. Fêmeas com ovos foram observadas apenas nos meses de março a junho, correspondendo ao período chuvoso da região. Os resultados encontrados no presente estudo são semelhantes aos observados em outras populações de caranguejos violinistas e sugerem que a população se encontra estável no ambiente. O presente estudo fornece subsídios para a conservação da espécie no manguezal do Rio Igaraçu.
