Published: November 2019

Cooperative is conventionally known an autonomous association of persons united voluntarily to meet their common economic, social, cultural needs and aspirations through a jointly owned and democratically controlled enterprise (International Cooperative Alliance,2014).  Despite of having a long tradition of cooperatives movement evidenced by the vast numbers of cooperatives (14,094 in June 2018) in Malaysia, cooperatives are still left far behind to become more competitive in order to not only satisfy their cooperators but also to the societies.  The emphasis on transformation of cooperatives as social entrepreneurship is clearly outlined in the third strategic thrust of National Entrepreneurship Framework 2018.  Thus, the current study aims to identify barriers that hinder cooperatives from safeguarding member’s wellbeing and further provide service to the communities.  A set of questionnaire which consists of two sections namely background of cooperative and barriers to social entrepreneur were distributed to the registered cooperatives who participated in Konvensyen Pemerkasaan Koperasi 2019.  Among barriers uncovered were lack of capital, involve in only conventional activities, weak structure, absence of good governance, lack of cooperation between cooperatives, lack of managerial talent and lack of integrity among the management and members in cooperatives.  Conclusions and recommendations were discussed.

Published: November 2019

Using the example of an analysis of an extreme lowering of temperature in Moscow in January 2017, the horizontal and vertical extent of the urban heat island against the background of a strong stable stratification of the atmospheric boundary layer is studied. The possibilities of measuring and monitoring the vertical structure of the atmosphere by means of ground-based remote sensing are investigated. The capabilities of the mesoscale model WRF, adapted for a detailed description of mixing processes in the atmospheric boundary layer, in reproducing the spatial dynamics of the temperature anomaly are demonstrated. The numerical estimates of the amplitude and vertical extent of the urban heat island are compared with the measurement accuracy and the total errors of the numerical predictions. Comparison of measurement data and numerical simulation results on the WRF model, using the example of a winter urban heat island in January 2017, showed that mesoscale synoptic models so far only capture the main features of the urban heat island. But deviations between model and observed temperature fields can reach 5 C.

Authors: Ivashkin V. V. , Guo Peng
Published: November 2019

The task of creating a stable orbit of the Apophis asteroid satellite as a homogeneous triaxial ellipsoid is investigated. The simulation of the motion of the spacecraft around the asteroid was performed taking into account the main perturbations: from the attraction of celestial bodies, asteroids non-sphericity and solar radiation pressure, and taking into account the asteroids own rotation. It is shown that it is possible to create a stable orbit of an asteroid satellite. This orbit can be used for a detailed study of the characteristics of the asteroid and the refinement of its orbit using ground radio measurements of the motion of a satellite equipped with a radio beacon.

Published: November 2019

Results of the hydrogeochemical study of bauxite-bearing lateritic mantles of the Futa Djallon-Mandingo Province, West Africa, have allowed us to first characterize the pore water of vadose and infiltration hydrogeological zone. Abundances of major components (aluminum and iron) of the water are shown to be few orders higher than are those typical of the other waters of lateritic mantles. The pore water is proved to be a major factor of matter redistribution over any bauxite-bearing lateritic profile.
Generalized localization for spherical partial sums of multiple Fourier series
Authors: Ashurov R. R.
Published: November 2019

In this paper the generalized localization principle for the spherical partial sums of the multiple Fourier series in the L2-class is proved, that is, if f L2 (ТN) and f = 0 on an open set ТN then it is shown that the spherical partial sums of this function converge to zero almost - ​everywhere on . It has been previously known that the generalized localization is not valid in Lp (TN) when 1 p 2. Thus the problem of generalized localization for the spherical partial sums is completely solved in Lp (TN), p 1: if p 2 then we have the generalized localization and if p 2, then the generalized localization fails.
Formation of drop-shaped inclusions based on Pt, Pd, Au, Ag, Bi, Sb, Te, As during crystallization of the intermediate solid solution in the Cu-Fe-Ni-S system
Authors: Sinyakova E. F. , Kosyakov V. I. , Goryachev N. A.
Published: November 2019

The phase and chemical composition of drop-shaped inclusions in directionally crystallized intermediate solid solution was studied. The initial melt contained (in mol.%): Fe 31,79; Cu 15,94; Ni 1,70; S 50,20; Sn 0,05; As 0,04; Pt, Pd, Rh, Ru, Ag, Au, Se, Te, Bi, Sb 0,03. Experimental data indicate the simultaneous crystallization of two types of liquids upon cooling of the initial sulfide melt. One of them is formed in the subsystem (Pd, Au, Ag)-(Bi, Sb, Te), and the second - in the subsystem Cu-(S, Bi, Sb, Te). When these liquids solidified, inclusions formed, which we divided into four classes. Class I has a eutectic-like structure with a matrix of Pd(Bi,Sb)xTe1-x solid solution and Au crystallites with Ag, Cu, and Pd impurities. Class II is formed from sulfosalts with inclusions of Bi and Au. Class III includes inclusions of sperrylite Pt(As,S)2. Class IV forms compound inclusions from fragments of classes I-III. The experiment described in the work showed a more complex behavior of noble metals and metalloid impurities during the crystallization of complex sulfide-metalloid melts compared with the previously described data of isothermal experiments.
Occurrence of “precursors” of PKP-waves in the layered radial-symmetric Earth
Authors: Fatyanov A. G. , Burmin V. Yu.
Published: November 2019

It is generally accepted that PKP‑waves precursors, which are observed on a real data ahead of PKP‑waves, are explained by scattering on small-scale inhomogeneities in the lower mantle. In this paper, a stable analytical solution (without interference) was obtained for the wave field of longitudinal waves in a layered (discrete) ball of planetary size. The calculations of the total wave field, rays and travel-time curves of longitudinal waves for the spherical model of the Earth AK135 with a carrier frequency of 1 hertz are presented. The analytical solution showed that at angles smaller than 145 degrees ahead of the PKP‑waves, low-amplitude waves appear, with a higher frequency of about 1,3 hertz. Indeed, these high-frequency oscillations have the form characteristic for waves scattered at a certain object. The ray pattern and the travel-time graph show that these high-frequency oscillations are due to exclusively to the spherical geometry of the Earth. This could be explained by the interference of refracted and reflected longitudinal waves in the bottom of a discrete outer core. This field propagates even further towards smaller angles due to the interference of diffraction waves.

¿Existe inclusión educativa o integración escolar en la silla?
Authors: Angie Estefany Mallama Yela
Published: November 2019

La construcción del presente artículo tiene como finalidad establecer una postura reflexiva sobre la compleja realidad afrontada por las instituciones educativas, en relación con la dinámica que ejerce la diversidad estudiantil; este es un tema de bastante controversial si se considera el impacto sobre el nivel y calidad de los procesos de enseñanza-aprendizaje en el aula. Por ende, el abordaje de la perspectiva mencionada desde los lineamientos que subyacen a la inclusión educativa, se asume desde la diversidad, como un componente natural en los procesos desencadenados en la formación escolar, pues cada estudiante representa un sin número de habilidades, capacidades, potencialidades y formas de pensar, que les diferencian uno del otro, con igual importancia en la construcción de saberes. No obstante, los aspectos prácticos de la inclusión en el aula parecen sortear equívocos en su aplicación, ya que en la mayoría de las ocasiones los entornos escolares no posibilitan el fortalecimiento, afianzamiento y desarrollo de esas particularidades que el estudiante posee; en este caso, más que hablar de inclusión, se hace evidente la necesidad de referirse a la integración escolar, la cual puede asociarse a la reunión o agrupación de estudiantes con diversidad de capacidades en un mismo escenario educativo, el cual no cuenta con las herramientas y estrategias suficientes para trabajar desde la diversidad.

Years Ago, the Minangkabau tribe Community in West Sumatera as the the largest matrilineal in the world, has a communal economic system based on the Minangkabau tradition with a proto-democratic system. This paper aims to analyze the comparison of traditional economies with Islamic economics. The research method is descriptive qualitative by conducting surveys and focused group discussion (FGD). The results show Minang people who obey the Islamic rules and Minang custom do not carry out the Islamic economy system. It is because the influence of social and cultural side such as the capitalist economy system. As a result, there will be less togetherness between people based on the philosophy of "Adat Basandi Sa'arak, Syarak Basandi Kitabullah".

Introduction/Aim: Congenital infections are an important cause of stillbirth
and perinatal morbidity. It is important to know the regional seropositivity
rates when making the decision to conduct antenatal screening tests. Therefore,
in this study, it is aimed to investigate the seropositivity of toxoplasma, rubella, and cytomegalovirus (CMV) in women of childbearing age. Material and Methods: During the period of January–2017 and January–2018,
Toxoplasma, Rubella, and CMV antibodies in Yozgat City Hospital microbiology
laboratory were retrospectively screened. Women between 15 and 47 years of age
were included in the study. Of them, for 2447 women, the results of
toxoplasmosis, for 2612 women of rubella and for 873 women of CMV serology and
their age were recorded in SPSS 15.0 statistical package program. Findings/Results: In our study, Toxoplasma IgM 0%, Toxoplasma IgG 27%,
Rubella IgM 1.3%, Rubella IgG 92%, CMV IgM 1.1%, CMV IgG 99% were found to be
positive. The mean age of the Toxoplasma IgG positive group was 30 ± 5.9, while
it was 27.7 ± 5.6 in the IgG negative group and this difference was
statistically significant (p: 0.00). Conclusion: We think that prenatal screening for Toxoplasma,
training of seronegative individuals and the treatment planning in case of
acute infection are important. It is recommended that screening for Rubella and
vaccination of seronegative women be given before or after pregnancy. However,
due to high CMV seropositivity it may be appropriate to screen only women at a
risk for transmission and to provide training in congenital CMV infection and
prevention measures.

INTRODUCTION: The effect of the absence or presence of the Palmaris longus tendon on pinch and grip strength was investigated in this study. Similarly, the effect of the presence or absence of the fifth superficial flexor digitorum on grip strength in the hand was studied. The aim of the present study was to assess the combined effect of these anatomical variations on pinch and grip strength. MATERIALS AND METHODS: In this cross-sectional study, 523 volunteers and their 1046 hands were enrolled. Each hand was assessed for the presence or absence of the Palmaris longus tendon and for variations in the fifth superficial flexor digitorum function. Then the grip and pinch power of the hands were measured with the Jammar Dynamometer. RESULTS: The presence or absence of Palmaris longus had no effect on grip strength in the individuals studied. Likewise, variations in fifth superficial flexor digitorum function had no effect on grip and pinch strengths. But the results of statistical testing showed the effect of the presence of Palmaris longus on pinch strength (25.38 lbs in hands with Palmaris present vs 24.43 lbs in hands without Palmaris). Pinch and grip power was higher in men than in women and in the right hand than in the left. CONCLUSION: Based on the findings of the present study, it seems that absence of the Palmaris longus tendon is associated with a reduction in pinch strength but has no effect on grip strength, and the variations in the fifth superficial flexor digitorum (flexor digitorum superficialis, or FDS) have no effect on pinch and grip strengths.

INTRODUCTION:

Stromal-epithelial interactions are fundamental for normal organ development and there is a multitude of evidence that the different components of the microenvironment are also necessary for the maintenance and promotion of the “tumor organ”. Deregulated tumor associated extracellular matrix (tECM) is a hallmark of cancer, causing an alteration in the amount and composition of the different components (i.e. proteins, proteoglycans, glycoproteins and polysaccharids) of the ECM. As epithelial-stromal interactions are reciprocal, it is possible that tECM itself is able to initiate tumor development. We therefore established a mouse model to examine the influence of tECM of murine breast cancer on developing breast tissue in mice.

MATERIALS AND METHODS:

Breast cancer was established in 5 BALB/c mice by subcutaneous injection of 1×106 4T1 cells in 100μl PBS into the left mammary fat pad. The mammary fat pad including the primary tumor was excised after two weeks, decellularised and labelled as tumor extracellular matrix (tECM). Tumor ECM of 4T1 tumors was implanted into the 4th inguinal mammary fat pad of BALB/c mice ( n = 5) aged 5 days. After 12 weeks the fourth mammary fat pad including the primary tumor was excised. Tissue was used for paraffin embedding and mouse breast cancer PCR array. Murine breast cancer tissue (BCT) and normal murine breast tissue (BT) served as control.

RESULTS:

Gene array analysis of 84 breast cancer-specific transcripts revealed that the mammary gland cells which were exposed to tumor ECM (tECM-BT) showed a similarly high overexpression for 22 genes as apparent for breast cancer tissue (BCT). The corresponding scatter plot showed a high agreement in the expression of the examined genes between the mammary gland cells which were exposed to tumor ECM and the breast cancer tissue.

DISCUSSION:

Our results clearly demonstrate that the tECM is able to shift the gene expression pattern of murine mammary epithelial cells towards that of carcinoma, indicating a role in breast cancer initiation. These data underlines that the acellular component of the tumor (ECM) can lead to a transformation of mammary gland tissue cells. These data show for the first time that the interaction of normal breast tissue cells with tumor ECM leads to an exchange of information and a consecutive overexpression of tumor-specific genes.
Moonlighting proteins - an approach to systematize the concept
Authors: Krantz Maria , Klipp Edda
Published: November 2019

Moonlighting refers to a protein with at least two unrelated, mechanistically different functions. As a concept, moonlighting describes a large and diverse group of proteins which have been discovered in a multitude of organisms. As of today, a systematized view on these proteins is missing. Here, we propose a classification of moonlighting proteins by two classifiers. We use the function of the protein as a first classifier: activating - activating (Type I), activating - inhibiting (Type II), inhibiting - activating (Type III) and inhibiting - inhibiting (Type IV). To further specify the type of moonlighting protein, we used a second classifier based on the character of the factor that switches the function of the protein: external factor affecting the protein (Type A), change in the first pathway (Type B), change in the second pathway (Type C), equal competition between both pathways (Type D). Using a small two-pathway model we simulated these types of moonlighting proteins to elucidate possible behaviors of the types of moonlighting proteins. We find that, using the results of our simulations, we can classify the behavior of the moonlighting types into Blinker, Splitter andSwitch.
Trusted smart statistics: Motivations and principles

Published: November 2019

In this contribution we outline the concept of Trusted Smart Statistics as the natural evolution of official statistics in the new datafied world. Traditional data sources, namely survey and administrative data, represent nowadays a valuable but small portion of the global data stock, much thereof being held in the private sector. The availability of new data sources is only one aspect of the global change that concerns official statistics. Other aspects, more subtle but not less important, include the changes in perceptions, expectations, behaviours and relations between the stakeholders. The environment around official statistics has changed: statistical offices are not any more data monopolists, but one prominent species among many others in a larger (and complex) ecosystem. What was established in the traditional world of legacy data sources (in terms of regulations, technologies, practices, etc.) is not guaranteed to be sufficient any more with new data sources. Trusted Smart Statistics is not about replacing existing sources and processes, but augmenting them with new ones. Such augmentation however will not be only incremental: the path towards Trusted Smart Statistics is not about tweaking some components of the legacy system but about building an entirely new system that will coexist with the legacy one. In this position paper we outline some key design principles for the new Trusted Smart Statistics system. Taken collectively they picture a system where the smart and trust aspects enable and reinforce each other. A system that is more extrovert towards external stakeholders (citizens, private companies, public authorities) with whom Statistical Offices will be sharing computation, control, code, logs and of course final statistics, without necessarily sharing the raw input data.

BACKGROUND: Over the past 20 years, magnetic resonance receiving coil technology has developed rapidly. The traditional, commercial knee joint coil has a fixed mechanical structure. To meet the imaging needs of most patients, it is necessary to ensure that the mechanical geometry of the coil is as large as possible. Therefore, different quality images can be obtained by filling coefficients under loads of knees of different sizes. Lufkin et al. [1] have demonstrated that the signal-to-noise ratio (SNR) of coil imaging is directly proportional to its filling coefficient, which is S/N≈QL*η. Thus, the pursuit of an optimal coil filling coefficient is an important way to improve the coil imaging quality. OBJECTIVE: This study combines wearable concepts and coil development techniques and applies flexible and elastic materials to coil designs. METHODS: We used an elastic material instead of the traditional fixed mechanical structure to develop a 1.5T 5-channel knee joint receiving coil that can be attached to knee joints of different sizes within a certain range, allowing the coil to achieve a maximum filling coefficient under the loads of knees of different sizes. RESULTS: Compared to commercial 8-channel knee coils, the phantom test and clinical knee joint imaging demonstrated that the SNR of the developed coil increased by four times in the shallow layer and two times in the deep layer, under different load conditions. CONCLUSION: This high SNR performance demonstrates potential for the realization of high resolution and fast imaging sequences in knee imaging.
Mythological worldview of fear and horror in ancient period
Authors: Turenko O.S.
Published: November 2019

The problem of the place and significance of the phenomena of fear and horror in the world-view of man has a long but unexplored history in science. Since ancient philosophy, these phenomena (especially fear) have been regarded as feelings that depend on the object-subjective perception of the phenomena of the socio-cultural life of society. However, none of the ancient authors put forward the original scientific hypothesis of the phenomenon and its justification. In modern times, fear in scientific circulation and everyday outlook has become purely natural-physiological (mechanical-materialistic) reaction of the nervous system of man to external danger. From the period of separation of psychology into a separate science and under the influence of the achievements of experimental psychophysiology of the early twentieth century. such a dominant awareness of fear has finally established itself and dominates the contemporary Western European outlook.
