Sociedad de la Información y Políticas de TIC en Venezuela
Authors: Bracho Espinel Francisco
Published: February 2023

El objetivo del presente trabajo es precisar las condiciones del avance de Venezuela hacia la Sociedad de la información (SI), a partir de las políticas implementadas en el sector de las tecnologías de la información y las comunicaciones (TIC), durante los gobiernos de Hugo Chávez (2001-2007 y 2007-2013) y Nicolás Maduro (2013-2019). Se realizó una investigación de tipo documental, con empleo de la técnica denominada análisis crítico sobre variados documentos a partir de los elementos hallados en ellos mediante el resumen analítico. Las teorías que fundamentan el estudio pertenecen a: Guerra y Jordán (2010); Vila (2002); De La Riva (2012); Hernández (2008); Gómez y otros (2008); entre otros. Se concluye que las políticas del sector TIC durante los gobiernos de Chávez y Maduro están orientadas hacia la consecución de una SI centrada en el desarrollo humano, pero en la práctica se descuida la alfabetización digital e informacional de la población, la ética y la participación. En materia de acceso a las tecnologías, Venezuela se encuentra rezagada en comparación con otros países de América Latina, producto de la limitada capacidad de la industria nacional para abastecer el mercado interno, de las restricciones en las importaciones y de los altos precios que hacen inaccesibles a la población los equipos electrónicos.
El Concepto de Poder en Economía
Authors: Osorio Bohórquez Leonardo Favio
Published: February 2023

El concepto de poder ha sido ampliamente estudiado en ciencias sociales en las últimas décadas, especialmente en el campo de la política y la sociología. Tradicionalmente, el poder había sido entendido como una forma de imponer la voluntad dentro de una dicotomía mandar-obedecer, como lo planteó Weber (2014). Actualmente, por medio de los aportes de Foucault (1996), se ha entendido ahora el poder en una perspectiva reticular a través de un conjunto de relaciones entre múltiples actores sociales. Sin embargo, en el campo específico de la Economía política, el poder poco ha sido estudiado por economistas, y ha sido trabajado más en la perspectiva simplista de control y apropiación de la riqueza y los medios de producción con base en una perspectiva marxista. De esa manera este artículo tiene como objetivo explicar el concepto de poder en el marco de la Economía política, con una visión interdisciplinar, sobre todo en el contexto de las actuales economías capitalistas. Fue utilizado el método analítico-sintético para la realización de la investigación por medio de una revisión bibliográfica. Se concluye que es necesario entender el poder en el campo de la Economía visto más allá de una perspectiva de confrontación y explotación entre ricos y pobres, sino como un conjunto de acuerdos, negociaciones, contratos y consensos entre múltiples sectores socioeconómicos y políticos, por medio de relaciones cambiantes y diversas dentro de una compleja trama de complejidades e intereses

Objective:  To assess the impact of intracranial pressure (ICP) monitored therapy on mortality in patients with severe traumatic brain injury.

Materials and Methods:  A randomized controlled trial was conducted at the Department of Neurosurgery, Jinnah Hospital Lahore. Forty patients of both genders, aged between 15 to 60 years were randomly selected and divided into two groups (Control & Experimental). Patients injured within 24 hours with a Glasgow Coma Scale (GCS) of 8 or less and showing radiological evidence of raised intracranial pressure were included. Patients with extradural hematoma, penetrating injury, or those requiring any surgery were excluded from the study. Data were analyzed using SPSS version 20.

Results:  No significant difference was found in mean age and gender among the two groups. The GCS of the control group was 6.2 ± 1.6 while that of the experimental group was 6.7 ± 1.6. The mean of the maximum ICP of the experimental group was 25.31 ± 8.48 mm of Hg. There was a significant difference in the mean duration of ventilation between the two groups. In the control group, 10 (50.0%) patients expired whereas in the experimental group, 8 (40.0%) patients expired. The proportion of mortality was higher in the control group but the difference was not statistically significant between the two groups (P value: 0.525).

Conclusion:  Intracranial pressure-monitored therapy was effective but statistically showed no significant superiority over unmonitored management.

Authors: Getaneh Demerew
Published: February 2023

Milk is produced, processed and utilized in different parts of Ethiopia and the majority in rural areas is processed at the household level into milk products using traditional technologies and marketed through informal channels. This study was initiated to assess and describe the traditional knowledge of milk production, handling, processing and utilization practices in South Ari and Malle district. Three dairy potential Kebeles from each district were selected via a purposive sampling procedure. Then, 196 households were selected through a systematic random sampling procedure. Data were collected using a semi-structure questionnaire and analyzed by SPSS (Version 23) software. There was a significant difference (P < 0.05) in livestock composition across the study districts. About 75% in South Ari and 72.9% in Malle have their own grazing land. Feed shortage (73%) and improved breed access (26%) in South Ari, and feed shortage (52.1%), drought (44.8%) in Malle were among the main constraints affecting dairying. About 65% of South Ari used plastic buckets for milking and clay pots for fermentation and churning. In Malle 88.5% used calabash containers for milking, accumulation and churning. The average days of raw milk fermentation before churning in South Ari and Malle were 4.2±0.1 and 2.9±0.0 days. The average butter-making time was 63.4±1.8 minutes in both districts. The amount of milk fermented and butter produced from this fermented milk is significantly different (P < 0.05) across districts. Nearly 95% of South Ari milk is traditionally processed into yogurt, butter, buttermilk and cheese; and used for home consumption and marketing. However, in Malle 72.9% of yogurt and buttermilk processing is used for home consumption; and 26% of butter processing is only used for marketing. It is possibly concluded that dairy production was commonly practiced and it was a good source of income in both districts. Therefore, it is vigorous to support the dairy linkage with extension services by enhancing the input provision.

Seed Germination of Coniferous Introduced Species in the Environment of Central Kazakhstan with Various Stratification and Inclusion of Needle Litter into Substrate
Authors:   Аcademician Y.A. Buketov Karaganda State University, Sirman Denis Yu.
Published: February 2023

This study observes the issues of the possible usage of wastes from timber industry in the sprouting of seeds of coniferous plants in the arid climate of Central Kazakhstan. Such treatment of coniferous seeds is easily implementable and cost-effective, compared to the other methods. However, the complex chemical composition of needle litter in the soil substrate has the multifactorial and controversial effects on such indicators as germination energy, seed germination capacity and rest energy. In addition, the article discusses the use of long-term natural seed stratification as an alternative method of planting seeds in forest nurseries. The other studies have shown that natural stratification has a more significant effect on the indicators of seed rest energy and germination energy. However, it should be said that these parameters mostly correlate with the generic assignment of the objects. Thus, representatives of the genera Picea and Abies have more significant rates of germination during spring stratification. Whereas, representatives of the genera Pinus and Pseudotsuga – with natural stratification. This may be the result of their ecological and biological adaptation. The conditions of Central Kazakhstan are characterized by a sharply continental climate, which includes not only a sharp climate change, but also a rather low snow cover and low temperatures. Under these conditions, the seeds of the genera Pinus and Pseudotsuga may have higher adaptive abilities, which may become a further subject of research. At the same time, it was determined that despite the rather convincing data obtained during autumn stratification, the highest results of seed germination in most experimental species were noted during spring stratification, including variation with the use of needle litter. Again, it is not entirely advisable to introduce the use of this method based only on the indicators of seed germination in arid conditions of Central Kazakhstan, since the favorable period for seed germination in this area is unstable from year to year. Thus, based on the results of the study, it was concluded that the most suitable method for germinating seeds of conifers, with some exceptions, is natural stratification. The use of needle litter affects insignificantly the rates of seed germination, and in some cases even suppresses this process.
Design Improvement of the Forestry Chain Saws

Published: February 2023

At the present time cutting of trees, delimbing, and crosscutting with gasoline-powered saws and logging machines are carried out in the forestry cutting area operations with the help of chain saws. Therefore, the efficiency of forestry work depends on the reliability and performance of the chain saw machine. The problem of increasing the reliability of sawing machines, increasing their service life becomes particularly relevant due to a sharp decrease in the volume of logging with the use of multi-operator logging machines. In this regard, the wide use of efficient motor tools, improvement of their design, especially the chain saw machine, with regard to reducing the harmful effect on the operator is of great importance. Poor quality and performance of domestic machinery has led to the fact that mainly imported tools are used in Russia, while their price and maintenance costs are constantly increasing and, consequently, the cost of harvested wood increases too. In this regard, it is important to develop and introduce new, more perfect tool designs that are not only as good as the reliability and performance of the imported equipment, but even much better. Taking it into account, we can consider that the issue of chain saw research with regard to the specifics of its design, as well as its science-based improvement will increase the operational performance and reliability of machines, which is important for the logging industry. One of the main causes of saw unit failures is the increased wear of its components accompanied by the improper saw chain tensioning. Currently, the proposed devices for regulating the tension of the saw chain require periodic stopping of the saw, as none of the devices provides its automatic tensioning. Thus, the purpose of the research is to improve the reliability and service life of chain saws of forestry machinery on the basis of improving the design that provides automatic tensioning of the saw chain. The paper describes the design solutions to improve the saw machine, that is the design of the device that provides automatic tensioning of the saw chain when the saw bar is fixed, allowing to increase the reliability and service life of chain saws, to reduce the chain slipping during the work, which will increase the safety of work and reduce the risk of injury to the operator.

Published: February 2023

The supply of the national economy with forest resources is directly related to transport accessibility, the condition and development of the road network of forest-rich territories. Construction requirements for year-round and seasonal new forest roads are 2.1 and 9.3 ths km per year, respectively. The situation is complicated by the transfer of transport facilities to new heavier live loads. The previously used design shapes of transport structures are outdated and require new engineering solutions. This is especially relevant for wooden bridge structures, which are of primary importance to forest road builders. The research subject is the wooden bridge girder superstructures with spans of 12–18 m undergoing increased road loads compared to the previous ones. The research aims is the development of modern designs of wooden beam superstructures based on the composite girders made of logs, board-bar-dowel-nail blocks and factory-made laminated blocks. The research includes: superstructures with composite girders of logs combined by combdowel joints, a method for calculating superstructures with composite girders, design of a 15-meter experimental superstructure containing composite log girders in joint operation with roadway reinforced concrete slab; new designs of 15–21-meter superstructures with board-bar-dowel-nail blocks A11 and NK-80 for live loads, design procedure and technology of block manufacturing, examples of designed and built bridges with the 15-meter superstructures; designs of multi-ribbed superstructures made of prefabricated transportable one-piece laminated sections containing laminated beams and a multilayer laminated timber slab. The proposed designes with composite girders of logs (beams) and board-nail blocks can be manufactured on the sites and yards of logging organizations using commonly used equipment, local qualified staff and materials. The cost parameters of permanent bridges built in the Omsk region with the use of these designs are 1.5–2 times lower than those of reinforced concrete analogues. The use of these designs will be effective in the pilot method of forestry development. The use of laminated superstructures is related to the modern phase of forest infrastructure development.

Increasing the profit received from 1 hectare of the developed forest area is one of the priority tasks of the forest industry today. This parameter describes the efficiency of forest management and affects the availability of wood resources. One of the possible solutions of this issue is the development of effective technological chains of manufacturing commodity products from wood felling residues. Currently, there are ample opportunities to obtain various products from harvested wood, including wastes from its logging and processing. The product range is significantly differentiated by cost and selling price. In Russia one of the important factors is the demand for certain types of products from wood resources, which is significantly inferior in its volume to foreign markets. Costs related to the manufacturing process are the most significant in the structure of production costs. Meanwhile, expenses may vary dramatically depending on the chosen technology, logistics, and specific production conditions in terms of the formation sources and specific weight in the overall structure. The set of factors that influence the choice of the type of products to be produced and, ultimately, the reasonable portfolio of commodity products, is not easy to consider in the issues of optimization. The study aims at forming a technological chain of processing felling residues at the stage of logging operations with obtaining an effective portfolio of commodity products under dynamic natural and production conditions. We propose to apply a graph-analytical model, in which the peaks of the graph are the cutting area, production operations, and а consumer. The arcs of this model are characterized by the carrying capacity limited by the productivity or volume of raw materials available for the operation, as well as the labor and costs (variable and constant). It should be mentioned that fixed costs arise primarily in the wood storage. A distinctive feature of the proposed model is the accounting of irrecoverable losses resulting from certain production operations and from the longterm storage of timber used for manufacturing commodity products including the costs of their disposal. The proposed graph-analytical model and procedure for solving the problem will allow determining the optimal technological chains of processing of wood felling residues with obtaining a commercial yield portfolio.

Studies in the field of hydrolysis of plant polysaccharides are ordinary classified according to protic reactions with diluted or concentrated acids. Such classification is based on the significant difference in the mechanisms of the reactions. The hydrolysis of polysaccharides of plant materials with the diluted acids is indicated by the concentrations of the mineral acids 0.5–10.0 % or happens by acid-free autohydrolysis, without any use of acids. Each of these reactions has considerably different kinetic and temperature-time parameters. They have both advantages and disadvantages. In particular, the hydrolysis using dilute acids is specified by a significant consumption of reagents and the presence of a large amount of carbohydrate degradation products in the hydrolysate. Autohydrolysis is characterized by a relatively low monosaccharide yield, high energy consumption for the process and the formation of many by-products. To date, studies regarding hydrolysis of polysaccharides of plant materials with acids in a concentration range of less than 0.5 % are absent. The reason for the lack of interest in research in this area, in our opinion, was the statement that acid in the process of hydrolysis is spent on the neutralization of ash components of plant materials at a flow rate of 5 to 20 g/kg of dry raw materials. Accordingly, when hydrolysis is carried out with ultra-low concentrations of acid, it is possible to completely neutralize it and switch the hydrolysis process from acid to acid-free autohydrolysis. The purpose of the work was to establish the efficiency of the hydrolysis process at ultra-low acid consumption. A study of the process of hydrolysis of hemicelluloses of birch wood at ultra-low concentrations of sulfuric acid was carried out. The possibility of almost complete hydrolysis of hemicelluloses with sulfuric acid with concentration of 0.10–0.25 % is shown. The process of hydrolysis of hemicelluloses with ultra-low acid concentrations is well described by the first order reaction. The general kinetic constants are calculated according to the experimental data. They show that the process occupies an intermediate position between acid-free autohydrolysis and traditional hydrolysis of hemicelluloses with sulfuric acid with a concentration of more than 0.5 %. The developed technique is advantageously different from the known methods of hydrolysis of hemicelluloses by low consumption of sulfuric acid (more than 5 times) and energy resources. Hemicellulose hydrolysates obtained by ultra-low acid concentration regimes have high benign properties and can be used in xylitol production.

The article deals with the effect of thinning in a permanent trial plot (PTP). The objects of care were natural clean even-aged pine forests growing in arid conditions of the Kazakh Uplands (case study of the Burabay National Park). The first thinning led by A.A. Weisman was carried out in 1994 in 25–30-year-old stands with the care intensity from 12.5 to 49.7 %. Besides the operating sections, the trial plot laid out during the research had control sections, where thinning was not carried out. The inventory indicators of the stands were determined, and the effects of thinning were analyzed in all the control and operating sections 70 years after the experiment began. The experiment proves that in dry pine forests of Northern Kazakhstan, the stock of stands in the operating sections, even 70 years after the care does not reach the volume of stock in the control sections. This also applies to the sections covered by low-intensity thinning. At the same time, thinning reduces the stock of ground flammable materials and deadwood. It increases the average diameter of trees relative to the care intensity. This enhances the fire resistance and recreational attractiveness of the plantations. An expanded distribution series of trees by natural diameter classes is observed in all sections: the number of natural diameter classes is 1.8 times greater than the normative distribution, which is one of the proofs of the specificity of the structure of the studied pine forests. The use of thinning with high intensity by the stock is the most promising. Dead standing, diseased and stunted trees are removed from the stand in the course of thinning. Thinning is recommended for 20–25 and 40–50 years old trees.

The article provides a description of the complex pneumatic fish protection structure (FCS) of the pumping station No. 1 of the Karmanovskaya GRES. Estimated design flow rate of NS No. 1 of water intake is 44 m3/s. The RGU includes an impenetrable screen in the form of a zapan, covering the surface two-meter layer of the water intake flow and a pneumatic (water-air) curtain that provides protection for fish fry of various sizes living in the thickness, surface and bottom layers of the reservoir.

Ichthyological studies conducted by the Tatar branch of the Federal State Budgetary Scientific Institution "VNIRO" showed that the complex pneumatic fish protection structure protects juvenile fish living in the reservoir with an average efficiency of 86.51%, which exceeds the regulatory requirements of 70% of the current SP 101.13330.2012 (updated edition of SNiP 2.06.07 -87 "Retaining walls, shipping locks, fish passage and fish protection structures" (as amended No. 1).
