Authors: Feijoo Calle Ernesto Patricio , Feijoo Guevara Bernardo Andrés 
Published: December 2020

This work presents a proposal for the characterization of the UnconfinedCompressive Strength test (UCS), through a series of operations that can be carried outwithout inconvenience in the field. Initially, fresh rock samples are obtained from outcropsin the area and specimens of specific dimensions are made. After the test specimenelaboration phase, crushing and granulometric classification tests are carried out witha set of specimens and in parallel with a second group, UCS tests are carried out. With theresults, the rock is characterized by graphing granulometric curves and in this graph theareas of fine granulometry are focused, inserting in these areas, the average value of UCS,with which it can be identified and determined when it is really necessary and It is inevitableto send rock samples to laboratories, thus saving time and money for the mining project.
Keywords: compression, crushing, granulometry, rock.

This article presents the results of our experiments in the farm “Shonli Dior Fayz” in the Buka district of Tashkent region, the results of studies on the occurrence, spread of white rot disease in sunflower, symptoms of the fungus pathogen, the harm of the disease and the biological effectiveness of the applied fungicides.
Due to the fact that none of the fungicides allowed for testing in the Republic of Uzbekistan was recommended for use against sunflower white rot disease, the recommended norms for other crops for diseases with white rot were tested.
Based on the biology of pathogens, fungicides were used as control measures: Fundazol 50% sp. - 2.0 kg / ha. and Difen super 55% sp - 0.25 kg / ha. and their biological efficiencies are determined
Variedades tradicionales de tomate de la Comunidad Valenciana del Banco de Germoplasma del COMAV
Authors: Díez Niclós María José 
Published: December 2020

El banco de germoplasma del COMAV conserva una colección de tomate de cerca de 3000 entradas. Más de 600 proceden de la Comunidad Valenciana. Ciento cincuenta y tres fueron recolectadas en la provincia de Alicante, 164 en Castellón y 315 en Valencia. Se dispone de datos de caracterización de una parte importante de las entradas. Ciento treinta y dos entradas pertenecen al tipo 'Valenciano' y fueron colectadas en expediciones de recolección realizadas desde principios de los años 80 hasta el presente. Cincuenta y una entradas del tipo 'Valenciano' han sido caracterizadas recientemente en El Perelló en cultivo de primavera-verano. De acuerdo a los datos referentes a la morfologia de fruto se han separado en cuatro grupos: “Masclet”, con frutos en forma de corazón y con el extremo estilar apuntado, característica propia de esta variedad, “Femella” con frutos más anchos y menos apuntados, “Xato” con frutos más achatados y acostillados, y “Rosada” con frutos de color rosa. Se encontró una elevada variabilidad para todos los descriptores tomados, excepto para tipo de crecimiento, siendo prácticamente todas las entradas de tipo indeterminado. El peso del fruto varió entre los 201 g del tipo “Rosada” y los 362 g en el grupo “Xato”. El grupo menos productivo fue el “Xato” con una producción moderada. En este caso, el elevado peso del fruto ocasiona un cuajado más irregular y consecuentemente se produce una disminución de la producción. El porcentaje más elevado de entradas con producción alta se encontró en el tipo “Femella”, con un 37% de las mismas con puntuación 7, siendo la puntuación máxima 9 para esta característica. La gran variabilidad encontrada para la mayoría de caracteres controlados y la adaptación a un amplio rango de condiciones agroclimáticas pone en valor esta colección para ser utilizada en programas de mejora o para cultivar directamente las mejores entradas.

A fast and efficient MATLAB-based MPM solver: fMPMM-solver v1.1
Authors: Wyser Emmanuel , Alkhimenkov Yury , Jaboyedoff Michel , Podladchikov Yury Y. 
Published: December 2020

Abstract. We present an efficient MATLAB-based implementation of the material point method (MPM) and its most recent variants. MPM has gained popularity over the last decade, especially for problems in solid mechanics in which large deformations are involved, such as cantilever beam problems, granular collapses and even large-scale snow avalanches. Although its numerical accuracy is lower than that of the widely accepted finite element method (FEM), MPM has proven useful for overcoming some of the limitations of FEM, such as excessive mesh distortions. We demonstrate that MATLAB is an efficient high-level language for MPM implementations that solve elasto-dynamic and elasto-plastic problems. We accelerate the MATLAB-based implementation of the MPM method by using the numerical techniques recently developed for FEM optimization in MATLAB. These techniques include vectorization, the use of native MATLAB functions and the maintenance of optimal RAM-to-cache communication, among others. We validate our in-house code with classical MPM benchmarks including (i) the elastic collapse of a column under its own weight; (ii) the elastic cantilever beam problem; and (iii) existing experimental and numerical results, i.e. granular collapses and slumping mechanics respectively. We report an improvement in performance by a factor of 28 for a vectorized code compared with a classical iterative version. The computational performance of the solver is at least 2.8 times greater than those of previously reported MPM implementations in Julia under a similar computational architecture.
Efeito dos Incentivos Fiscais na Geração e Distribuição de Riqueza das Companhias De Capital Aberto Brasileiras.

Published: December 2020

Os incentivos fiscais surgem para fomentar o desenvolvimento econômico setorial e regional. A Demonstração do Valor Adicionado (DVA) é demonstrativo contábil destinado a divulgar informações referentes à geração e distribuição de riqueza das empresas. Diante o exposto, o estudo tem como objetivo verificar o efeito dos incentivos fiscais na geração e distribuição de valor das empresas da Brasil, Bolsa, Balcão (B3). A amostra foi composta por 193 companhias da B3, no período de 2010 a 2018, e o método utilizado foi o de dados em painel estimado pelo método de Mínimos Quadrados Generalizados (MQG). Os resultados indicam que as companhias incentivadas geram mais riquezas, possuem maior distribuição de valor para o governo e menor distribuição para o pessoal. Portanto, as políticas de concessão de incentivos fiscais, no Brasil, não estão contribuindo para aumento de emprego e renda. Estes resultados estão em consonância à literatura internacional inerente ao tema, demonstrando que a distribuição de valor não é horizontal, pois não há um aumento de forma igualitária para os todos envolvidos nas companhias incentivadas, e tampouco gera maior distribuição de renda para pessoal, uma das justificativas para concessão destes incentivos. Diante disso, os órgãos reguladores e de arrecadação devem avaliar eficiência da concessão destes incentivos, já que eles podem não proporcionar os benefícios esperados para a sociedade.
Bleeding
Authors: Omona Kizito 
Published: December 2020

Fibroid, also called leiomyomas, is common tumor of the uterus. Usually, women of reproductive age are at risk of getting it. However, majority of these women develop fibroid (s) by the age of 50 years. This condition usually causes painful and unpleasant symptoms such as; heavy bleeding, prolonged periods, inter-menstrual bleeding, abdominal pain and cramps, anemia, pelvic pain and pain during sexual intercourse, among others. Abnormal bleeding, such as bleeding that occurs with fibroids and heavy periods, often lasts more than 10 days per month. This fibroid symptom involves persistent bleeding between cycles, which can severely impact one’s quality of life. Abnormal bleeding, especially in fibroids, can be taken as missing three or more periods in a woman who had been having regular monthly period, or periods that last less than 21 days or more than 35 days apart from each other. Another indication of an abnormal period is bleeding through multiple pads and tampons in a short amount of time.
The work integration social enterprises in Greece
Authors: Douvitsa Ifigeneia - 
Published: December 2020

The present paper focuses on the available legal forms with work integration as their explicit purpose in the Greek legislature and outlines their main traits on the basis of the EMES (European Research Network) nine criteria of social enterprises. Their thus far implementation is also discussed, including the challenges and shortcomings that WISEs have faced in the Greek context.The main findings of the study indicate a dominance of the cooperative form for the WISEs under the Greek context. More specifically, the legislator imposes a percentage of members coming from the target group, perceiving in that way mutuality and solidarity as rather intertwined, since the WISEs’ explicit aim of work integration of the disadvantaged people is mainly achieved by joining the cooperative. Despite the supportive measures for the WISEs, the implementation of the thus far public policies has not been effective in further promoting such a model of enterprise.

Published: December 2020

Backround
We compared postoperative outcomes in adolescent patients who did and did not undergo plate-screw fixation of at least one of the lateral, medial, or posterior malleoli in ankle fractures. It was hypothesized that using plate-screw fixation would not negatively affect postoperative outcomes.

Methods
All of the preoperative data and postoperative outcomes for 56 patients with ankle fractures aged 12 to 15 years who underwent surgical treatment between January 1, 2007, and December 31, 2017, were reviewed retrospectively. Patients were grouped into plate-screw fixation (n = 15) and non–plate-screw fixation (n = 41) groups and as high- and low-energy trauma patients.

Results
There were no significant differences in postoperative outcomes between the plate-screw fixation and non–plate-screw fixation groups. The mean American Orthopaedic Foot & Ankle Society score of high-energy trauma patients was significantly lower than that of low-energy trauma patients (P < .001), and the rate of degenerative change in high-energy trauma patients was significantly higher than that in low-energy trauma patients (P = .008). There were no significant differences between high- and low-energy trauma patients with respect to other postoperative outcomes.

Conclusions
If anatomical reduction is performed without damaging the growth plate, postoperative clinical outcomes may be near perfect regardless of screw-plate fixation use. Postoperative outcomes of adolescent ankle fracture after high-energy trauma, independent of Salter-Harris classification and surgical treatment methods, were negative.
Determinants of behavioural and biological risk factors for cardiovascular diseases from state level STEPS survey (2017–19) in Madhya Pradesh
Authors: Kokane Arun M. , Joshi Rajnish , Kotnis Ashwin , Chatterjee Anirban , Yadav Kriti , Revadi G , Joshi Ankur , Pakhare Abhijit P. 
Published: December 2020

Background
National and statewide assessment of cardiovascular risk factors needs to be conducted periodically in order to inform public health policy and prioritise allocation of funds, especially in LMICs. Although there have been studies from India which have explored the determinants of cardiovascular risk factors, they have mostly been from high epidemiological transition states. The present study assessed the determinants of cardiovascular (CVD) risk factors in a low epidemiological transition state (Madhya Pradesh) using the WHO STEPwise approach to surveillance (STEPS).

Methods
A total of 5,680 persons aged 18–69 years were selected from the state of Madhya Pradesh through multi-stage cluster random sampling. Key CVD risk factors we sought to evaluate were from behavioural (tobacco, alcohol, physical activity, diet) and biological domains (overweight or obese, Hypertension, Diabetes, and Raised serum cholesterol). Key socio-demographic factors of interest were the caste and tribe groups, and rural vs urban location, in addition to known influencers of CVD risk such as age, gender and education level

Results
Those belonging to the scheduled tribes were more at risk of consuming tobacco (OR 2.13 (95% CI [1.52–2.98]), and a diet with less than five servings of fruits and vegetables (OR 2.78 (95% CI [1.06–7.24]), but had had the least risk of physical inactivity (OR 0.31 (95% CI [0.02–0.54]). Residence in a rural area also reduced the odds of physical inactivity (OR 0.65 (95% CI [0.46–0.92])). Lack of formal education was a risk factor for both tobacco consumption and alcohol intake (OR 1.40 (95% CI [1.08–1.82]) for tobacco use; 1.68 (95% CI [1.14–2.49]) for alcohol intake). Those belonging to schedules tribes had much lower risk of being obese (OR 0.25; 95% CI [0.17–0.37]), but were at similar risk of all other clinical CVD risk factors as compared to other caste groups.

Conclusion
In the current study we explored socio-demographic determinants of behavioural and biological CVD risks, and found that in Madhya Pradesh, belonging to a scheduled tribe or living in a rural location, protects against being physically inactive or being overweight or obese. Increasing age confers a greater CVD-risk in all domains. Being a male, and lack of formal education confers a greater risk for behavioural domains, but not for most clinical risk domains. Future efforts at curbing CVDs should be therefore two pronged –a population-based strategy targeting biological risk factors, and a more focussed approach directed at those displaying risky behaviour.
Neurotrophic effect of hematopoietic cytokines on cholinergic and other neurons in vitro
Authors: Tabira T. , Konishi Y. , Gallyas F. 
Published: July 2002

AbstractWe examined the effects of interleukin‐3 (IL‐3) and other hematopoietic cytokines on the neurotransmitters, neurite formation, and differentiation in cholinergic and other types of neurons. IL‐3, granulocyte‐macrophage colony‐stimulating factor (GM‐CSF), macrophage colony‐stimulating factor, granulocyte colony‐stimulating factor and erythropoietin (Epo) elevated choline acetyltransferase (ChAT) activity in septal cholinergic cell line SN6 as well as in primary cultured septal neurons without increasing protein contents of the cells. These effects were dose‐dependent and the optimal doses were not different from those for blood cells. IL‐3 had neurite‐promoting activity but GM‐CSF had no such effect. Both IL‐3 and GM‐CSF decreased intracellular acetylcholine concentration, and elevated glutamic acid decarboxylase and intracellular GABA in septal neuronal cultures. Epo elevated monoamines in PC12 cells. These effects are thought to result from direct action through their specific receptors in neurons, because (i) anti‐IL‐3‐receptor antibody abolished the ChAT activity in septal neurons increased by IL‐3; (ii) mRNA and immunoreactivity for β subunits of IL‐3 receptors were expressed in septal cholinergic neurons and (iii) presence of receptos for GM‐CSF and Epo in neurons has been reported. Our observation and others strongly support that neural‐immune interactions are important not only in the defense mechanism in the nervous system but also in the development, differentiation and function of neurons.
