Atenuación y posibilidad: interacciones entre dos contenidos procedimentales
Authors: Fuentes Rodríguez Catalina 
Published: February 2020

El estudio de la atenuación implica tener en cuenta el contenido léxicosemántico de las expresiones, las construcciones en las que aparecen y la presencia de operadores especializados. El presente trabajo analiza dos construcciones, en la medida de lo posible y en lo posible, describe sus usos y los contenidos procedimentales que expresan, que van en dos direcciones: la limitación de la referencia (función marco, argumentativa, ligada al concepto de posibilidad) y la atenuación discursiva (estrategia a la que sirven cuando la minimización afecta a la fuerza ilocutiva). Además, se plantea el grado de fijación de ambas construcciones para determinar si pueden ser consideradas ya operadores discursivos
The study of attenuation implies taking into account the lexical-semantic content of the expressions, the constructions in which appear and the presence of specialized operators. This paper analyzes two constructions, en lo posible and en la medida de lo posible, describes their uses and the procedural meanings they convey, which goes in two directions: the limitation of the reference (argumentative framework function, linked to the concept of possibility) and the discursive attenuation (strategy they serve when minimization affects the illocutive force). The degree of fixation of both constructions is also discussed in order to determine whether they can already be considered discursive operators.
Condicionantes sociolingüísticos en la expresión del sujeto pronominal en el corpus PRESEEA-Sevilla: el sociolecto alto
Authors: Repede Doina 
Published: February 2020

Este trabajo se propone analizar la variable presencia / ausencia del pronombre personal sujeto junto a un verbo conjugado en el español hablado de la comunidad urbana de Sevilla. En concreto, intentamos establecer cuáles son los factores internos y externos que determinan el empleo del sujeto pronominal en una muestra de 24 entrevistas semidirigidas correspondientes al sociolecto alto y que forman del corpus PRESEEA en la ciudad. Para ello, seguimos la guía de codificación propuesta por Bentivoglio, Ortiz y Silva-Corvalán (2011) para el proyecto panhispánico PRESEEA. Los resultados muestran que el pronombre sujeto se utiliza un 24,8%, y parece estar condicionado, entre otros, por criterios como persona gramatical, especificidad, ambigüedad de la forma verbal, clase semántica del verbo, correfencialidad, edad, etc.
This study aims to analysis the variable presence/absence of the personal pronoun subject with a conjugated verb in Spanish language spoken in the city of Seville. Specifically, we try to stablish which internal or external factors are involved in the pronominal subject use in a sample of 24 semi-controlled interviews corresponding to the high sociolect and taken from the PRESEEA-Seville corpus. For this, we base our analysis on the coding guidelines proposed by Bentivoglio, Ortiz and Silva-Corvalán (2011) for the PRESEEA panhispanic project. The results show that the subject pronoun is used in 24,8% and it is conditioned by different criteria, such as grammatical person, specificity, ambiguity of the verbal form, semantic class of the verb, co-reference or age.

Authors: Fernández Jaén Jorge 
Published: February 2020

El propósito de este artículo es presentar una caracterización sintáctica y semántica de los verbos llamarse y apellidarse efectuada desde los presupuestos de la lingüística cognitivo-funcional. Nuestro objetivo es poner de manifiesto cómo funcionan estos verbos en español, cuáles son sus peculiaridades conceptuales (peculiaridades muy notables en el contexto de las lenguas europeas) y cuáles son las posibles razones -históricas y lingüísticas- por las que estas formas verbales pronominales y no otras se utilizan en español para expresar el nombre propio y el apellido. El trabajo ofrece reflexiones originales acerca de estos verbos e hipótesis novedosas sobre la relación entre los verbos de habla, la reflexividad, la representación de uno mismo y la fuerza ilocutiva del lenguaje.
This article has as its purpose to offer a syntactic and semantic profile of the verbs llamarse and apellidarse carried out from the postulates of cognitive-functional linguistics. It i sour intention to: (a) show how these verbs work in Spanish; (b) identify their conceptual peculiarities (which are quite remarkable within the context of European languages); and (c) explain the possible -historical and linguistic- reasons why these pronominal verbs, and not others, are used to express the Christian name and the surname in Spanish. This work provides original and the illocutionary force of language.
Using ARIMA Models to Forecasting of Economic Variables of Wheat Crop in Afghanistan
Authors: Karim Ahmadzai M. , Eliw Moataz 
Published: February 2020

Wheat is considered the main food crops in Afghanistan, whether to use it for majority of the population consumption or to use it in some industries and others.
Problem: Afghanistan suffers from a large gap between production and consumption, so the current research investigates the problem arising from a shortage of wheat production to meet self-sufficiency of the population.
Methods: The time series analysis can provide short-run forecast for sufficiently large amount of data on the concerned variables very precisely. In univariate time series analysis, the ARIMA models are flexible and widely used. The ARIMA model is the combination of three processes: (i) Autoregressive (AR) process, (ii) Differencing process and (iii) Moving-Average (MA) process. These processes are known in statistical literature as main univariate time series models and are commonly used in many applications. Where, Estimation of future wheat requirement is one of the essential tools that may help decision-makers to determine wheat needs and then developing plans that help reduce the gap between production and consumption. A solid strategy that widely applying of improved seeds and fertilizers, an effective research and extension system for better crop management is necessary to eliminate this gap for self-sufficiency in wheat production, besides providing the necessary financial sums for that. Where most prediction methods are valid for one-year prediction. However, moving prediction methods have been found to measure and predict the future movement of the dependent variable.
Aims: The current research aims to prediction for Area, Productivity, Production, Consumption and Population over the period (2002-2017), to estimate the values of these variables in the period of (2018-2030).
Results: The results showed that through the drawing of the historical data for Planted area, Productivity, Production, Consumption and Population of wheat crop it was evident that the series data is not static due to an increasing or a decreasing of general trend, which means the instability of the average, by using Auto-correlation function (ACF) and Partial Correlation Function to detect the stability of the time series, The results showed also, the significance of Autocorrelation coefficient and partial correlation coefficient values, which indicates that the time series is not static.

Published: February 2020

Background: Reports has shown that edible leaves of vegetable plants serve both nutritional and medicinal purposes, yet are poorly utilized due to inadequate enlightenment of the major populace on their compositions.
Aims: The aim of this study was to determine the proximate, phytochemicals and reducing power of leaf extracts of Colocasia esculenta and Ipomoea batatas.
Methodology: Washed and air dried leaf samples were milled and subjected to proximate and phytochemical analysis. Determination of calcium, iron and sodium content was by Atomic absorption spectroscopy. Reducing power was determined by the Potassium ferricyanide reducing power method.
Results: Ipomoea batatas leaves was found to be higher in moisture (14.05%) and carbohydrate (29.33%) while Colocasia esculenta leaves was higher in ash (10.00%), Crude fiber (16.27%), Fat (10.17%) and protein (29.41%). A better antioxidant activity and higher levels of all phytochemicals and minerals were observed in leaves of Colocasia esculenta compared to leaves of Ipomoea batatas.
Conclusion: This study suggests that both leaves are of importance to human nutrition considering the observed levels of nutrients, phytochemicals and antioxidant activity. While C. esculenta leaves should be preferred for its nutrient and antioxidant advantages, both leaves can contribute immensely to the daily nutrient requirements.
Laser DAF Cut Augmentation for Thin Wafers
Authors: Christian Bacquian Bryan , Ray Gomez Frederick 
Published: February 2020

The semiconductor industry is becoming more inclined to thinner integrated circuit (IC) packages. Thinner packages with thin wafer or die prefer the die attach film (DAF) technology as the die adhesive material solution. As the wafer goes thinner, it becomes more of a challenge in process development, especially during its assembly preparatory stages. As the dies become smaller and thinner, wafer sawing process should have minimum effect on the mechanical integrity of the silicon so as not to alter its quality.
New technologies were developed and introduced in the industry and one of this is the laser die attach film (DAF) cutting. The method was developed together with dies before grinding (DBG) as a cutting medium to address potential processability problems that may occur on the conventional mechanical blade saw. This paper discusses the laser DAF cut development covering the design of experiments (DOE) to understand the different characteristics of laser DAF solution. Validations are made through actual simulation and wafer processing. The paper also covers the interaction of different DAF thicknesses and parameters in order to define the critical characteristics in achieving optimal DAF cutting process responses.

Background: Constipation is one of the symptoms of intestinal syndrome which would be happened along with some other disease in patients. There are several treatment available to cure the constipation but use of stimulant laxative in chronic and acute constipation is more safe and useful of any age patients. In this cross sectional study we clinically observed the efficacy of multi herbal extract (Cassia senna, Rheum palmatum and Cuscuta reflexa) in constipation. We have used local company syrup (EZCol syrup). This syrup contains multi herbs and senna leaves extract is main ingredient of this syrup. The active constituents of enna leaves are Sennosides which considered as an effective treatment for constipation. Sennosides increase the transfer rate of materials from the large intestine. We aimed to assure the effect of senna leaves extract along with other herbal extract (Rheum palmatum and Cuscuta reflexa) for the treatment of constipation.
Materials and Methods: In this study, 35 patients were observed after taking the syrup (dose 15 mL 2 time/daily for 3 days). A questionnaire (ROUTE2-003) was developed and distributed to the patients after prescription of EZCol syrup. The study was approved form ethical committee of Rashid Lateef Medical College and Arif Memorial Teaching Hospital, Lahore Pakistan.
Results: Treatment was continued for 3 days and data was compiled and result shown significant cure in constipation. Maximum patients felt relief from constipation just within 3 days. Some patients felt diarrhea at third day. Moreover no further significant complications were found in patients.
Conclusion: Senna is an FDA-approved over-the-counter (OTC) laxative. Senna leaves extract is a safe, effective and well-tolerated herbal supplement for the treatment of constipation having no significant adverse effect.
Blockchains and Internet of Things for the Pooling of Warehouse Resources
Authors: Liu S. , Roy D. , Hennequin S. 
Published: February 2020

Aims: The purpose of this research paper is the study of the applicability of Blockchain technology and Smart Contracts to manage, control and secure an industrial Internet of Things network (IoT) for pooled warehouses with multiple actors and activities (not only restricted to transport and storage as currently developed in enterprises).
Problem: IoT technology enables things to connect and exchange data, resulting in efficiency improvements, economic benefits, reduced human intervention and enabled interactions (information exchange and analysis) between human/machine to machine. However, the main difficulties lie in the definition of a robust global mechanism to secure the IoT, the awareness of resources diversity (heterogeneity of devices), and physical management of IoT. This article will attempt to answer these questionings.
Results: To respond to these questions, we propose a hybrid architecture based on blockchains and multi-agents system to secure an industrial IoT corresponding to a pooled warehouse system. The proposed hybrid architecture completely represents our system, with all actors and connected objects in the pooled warehouse strategy. It is composed by two parts: a centralized part based on the multi-agents system to represent dynamic evolutions of actors’ behavior and a decentralized part, which corresponds to our block chain and smart contracts network to dynamically connect actors’ agents to pooled resources. The multi-agent system is coupled with game theory (cooperative game) to have a good systemic representation of our pooled warehouse management problem.

Endosymbiosis before eukaryotes: mitochondrial establishment in protoeukaryotes
Authors: Zachar István , Boza Gergely 
Published: February 2020

AbstractEndosymbiosis and organellogenesis are virtually unknown among prokaryotes. The single presumed example is the endosymbiogenetic origin of mitochondria, which is hidden behind the event horizon of the last eukaryotic common ancestor. While eukaryotes are monophyletic, it is unlikely that during billions of years, there were no other prokaryote–prokaryote endosymbioses as symbiosis is extremely common among prokaryotes, e.g., in biofilms. Therefore, it is even more precarious to draw conclusions about potentially existing (or once existing) prokaryotic endosymbioses based on a single example. It is yet unknown if the bacterial endosymbiont was captured by a prokaryote or by a (proto-)eukaryote, and if the process of internalization was parasitic infection, slow engulfment, or phagocytosis. In this review, we accordingly explore multiple mechanisms and processes that could drive the evolution of unicellular microbial symbioses with a special attention to prokaryote–prokaryote interactions and to the mitochondrion, possibly the single prokaryotic endosymbiosis that turned out to be a major evolutionary transition. We investigate the ecology and evolutionary stability of inter-species microbial interactions based on dependence, physical proximity, cost–benefit budget, and the types of benefits, investments, and controls. We identify challenges that had to be conquered for the mitochondrial host to establish a stable eukaryotic lineage. Any assumption about the initial interaction of the mitochondrial ancestor and its contemporary host based solely on their modern relationship is rather perilous. As a result, we warn against assuming an initial mutually beneficial interaction based on modern mitochondria–host cooperation. This assumption is twice fallacious: (i) endosymbioses are known to evolve from exploitative interactions and (ii) cooperativity does not necessarily lead to stable mutualism. We point out that the lack of evidence so far on the evolution of endosymbiosis from mutual syntrophy supports the idea that mitochondria emerged from an exploitative (parasitic or phagotrophic) interaction rather than from syntrophy.

Abstract
Background
Small bowel vascular malformation disease (SBVM) is the most common cause of obscure gastrointestinal bleeding (OGIB). Several studies suggested that EGFL6 was able to promote the growth of tumor endothelial cells by forming tumor vessels. To date, it remains unclear how EGFL6 promotes pathological angiogenesis in SBVM and whether EGFL6 is a target of thalidomide.

Methods
We took advantage of SBVM plasma and tissue samples and compared the expression of EGFL6 between SBVM patients and healthy people via ELISA and Immunohistochemistry. We elucidated the underlying function of EGFL6 in SBVM in vitro and by generating a zebrafish model that overexpresses EGFL6, The cycloheximide (CHX)-chase experiment and CoIP assays were conducted to demonstrate that thalidomide can promote the degradation of EGFL6 by targeting CRBN.

Results
The analysis of SBVM plasma and tissue samples revealed that EGFL6 was overexpressed in the patients compared to healthy people. Using in vitro and in vivo assays, we demonstrated that an EMT pathway triggered by the EGFL6/PAX6 axis is involved in the pathogenesis of SBVM. Furthermore, through in vitro and in vivo assays, we elucidated that thalidomide can function as anti-angiogenesis medicine through the regulation of EGFL6 in a proteasome-dependent manner. Finally, we found that CRBN can mediate the effect of thalidomide on EGFL6 expression and that the CRBN protein interacts with EGFL6 via a Lon N-terminal peptide.

Conclusion
Our findings revealed a key role for EGFL6 in SBVM pathogenesis and provided a mechanism explaining why thalidomide can cure small bowel bleeding resulting from SBVM.
Persist or perish: critical life stages determine the sensitivity of invertebrates to disturbances

Published: February 2020

AbstractA large proportion of studies assessing the impact of disturbances on the invertebrate community composition focus on a single life stage, assuming that those are an adequate indicator of environmental conditions. The effect of a specific disturbance may, however, depend on the life stage of the exposed organism. Therefore, we focused on the effect of spates on the caddisflyAgapetus fuscipesCURTIS (Trichoptera: Glossosomatidae) during different larval stages. A 2 year field study was performed in which we measured the discharge dynamics and population development ofA. fuscipesin four lowland streams in The Netherlands. A stage-structured population model (i.e. StagePop) was used to test the impact of peak discharge on the different life stages, as larval instars 1–4 were not effectively sampled in the field. Four different mortality rates in response to spates were simulated, including a constant low, a constant high, a decreasing and an increasing impact per larval stage. This way, we were able to show a potential association between spates and population declines, where the stage-population model including decreasing impact by spates with increasing larval life stage most accurately described the population development of the larval instars 5–8. Focusing only on late instars could thus potentially result in underestimation of the effects of spates on this species. In conclusion, determination of responses of critical life stages to specific disturbances may help to identify the causes of the presence and absence of species, and thereby aid more effective management and restoration of degraded aquatic systems.
