Rediseño institucional para el cierre de brecha residual de telecomunicaciones en Perú: Una tercera vía de intervención para la emergencia de redes comunitarias sostenibles
Authors: Ramírez García Alan Alberto , Blanco Romero Gislayne
Published: August 2021

El problema de falta de conectividad en gran parte del mundo ha sido más expuesto a raíz de la pandemia de la COVID-19; particularmente, en América Latina y el Caribe, así como en el Perú, se ha atestiguado cómo la falta de acceso a Internet limita las condiciones de desarrollo y agranda las brechas sociales y económicas entre los conectados en las áreas urbanas y los no conectados en las rurales. La multidimensionalidad de este problema se encuentra la concurrencia de causas estructurales y profundas que, en el tiempo, han sido ya ampliamente diagnosticadas. En tal sentido, este trabajo, enfocado en Perú, pero potencialmente aplicable a América Latina y el Caribe, propone como nuevo aporte la definición de la brecha residual de telecomunicaciones rurales («brecha residual»), entendida como el conjunto de localidades no priorizadas ni priorizables por el sector privado ni por las intervenciones públicas tradicionales en el corto ni el mediano plazo. Asimismo, se analiza la efectividad del diseño institucional actual con el que se atiende, desde el Estado, a la brecha de conectividad y se propone, para el conjunto de «brecha residual», incorporar una tercera vía: un modelo de gobernanza bottom-up para la emergencia de redes comunitarias sostenibles. Por sus características, esta tercera vía demanda la reconfiguración multiestamental de roles y habilita la inclusión de enfoques de territorialidad e interculturalidad en diversos espacios geográficos. Finalmente, si bien las localidades que integran la brecha residual se caracterizan por una serie de condiciones desfavorables para la provisión tradicional de servicios de telecomunicaciones u otros, para el caso rural peruano, un gran conjunto de la brecha residual cuenta con un vasto tejido social comunitario, ajeno a las telecomunicaciones (v.g. comunidades campesinas, pueblos indígenas, asociaciones de agua y riego, etc.). Esta condición previa se presenta como una gran ventaja para la aplicación exitosa del modelo de redes comunitarias propuesto en el rediseño institucional, su caracterización e identificación de oportunidades es el tercer aporte de este trabajo.
Tópicos en la Regulación de Internet: congestión de tráfico y neutralidad de red
Authors: Bruno Néstor
Published: August 2021

Una práctica de transmisión de datos en internet que se desvíe del precepto general conocido como “mejor esfuerzo” es calificada como una violación al principio de neutralidad de red. Presentamos un modelo no neutral de contrato entre proveedores de acceso a internet (ISP) y proveedores de contenido (CAP) en base al concepto de tráfico priorizado. Evaluamos sus beneficios comparándolo con una situación neutral y hallamos que en la modalidad no neutral se reduce el cargo. La modelización de la congestión de red en conjunto con la determinación de los beneficios de ISP y CAP y la consideración de una forma específica de trafico administrado genera resultados que difieren de los argumentos regulatorios simples donde siempre es beneficioso para los ISP apartarse del régimen de neutralidad de red y extraer parte de los recursos de los proveedores de contenido (CAP) a pesar que aun en éste caso el excedente total del mercado puede aumentar.

Postoperative Patient-reported Pain and Opioid Consumption After Total Hip Arthroplasty: A Comparison of the Direct Anterior and Posterior Approaches
Authors: Bovonratwet Patawut , Chen Aaron Z. , Shen Tony S. , Ondeck Nathaniel T. , Kunze Kyle N. , Su Edwin P.
Published: August 2021

Introduction:

Although one of the touted benefits of the direct anterior approach (DAA) includes decreased postoperative pain, there is no consensus on the effect of surgical approach on postoperative pain and subsequent analgesic consumption.

Methods:

Consecutive patients undergoing total hip arthroplasty by a single surgeon from May 2016 to March 2020 were identified. Procedures were categorized as DAA or posterior approach. Patient demographics and surgical details were assessed. Patient-reported maximum pain by postoperative day (POD), total opioid consumption during hospitalization, and whether the patient required a refill of opioid prescription within 3 months after discharge were compared between the two surgical approaches through multivariate analyses.

Results:

A total of 611 patients were included in this study (447 DAA and 164 posterior approaches). On multivariate analyses that controlled for preoperative/intraoperative differences, patients in the DAA group had lower average maximum reported pain (0 to 10 scale) on POD #0 (6.5 versus 6.8, P = 0.034) and POD #1 (5.4 versus 6.1, P = 0.018). However, the DAA was not associated with a statistically significant reduction in total inpatient oral morphine equivalents consumed (79.8 versus 100.1, P = 0.486). Furthermore, there was no association between surgical approach and opioid prescription refill within 3 months after discharge (P = 0.864).

Discussion:

The DAA was associated with slightly lower patient-reported pain. Furthermore, statistical analysis did not provide the necessary evidence to reject the null hypothesis, which was that there would be no difference in opioid utilization between the two approaches. Other perioperative factors may be more important to opioid use reduction than the surgical approach alone.

Authors: Daraei Mona , Kalantari Heibatullah , Khoragani Zahra Nazari
Published: August 2021

Backgrounds and aims: Nutrition is the main way to receive the trace elements that human body needs. Lithium (Li) and calcium (Ca) are two trace elements, which have important roles in human body. There are a few studies about the amounts of calcium and lithium in canned tuna fish. The aim of this study was to determine the concentrations of calcium and lithium in canned tuna fishes.

Materials and Methods: To this aim, 150 samples of canned tuna fishes from two well-known brands (Majid and Poolak), marketed in Khuzestan province of Iran, were obtained. Li contents of the samples were measured by atomic absorption spectrometry (AAS) with atomization in graphite furnace. Ca contents of the samples were measured by AAS using nitrous oxide-acetylene flame.

Results: The mean concentrations of calcium in canned tuna fish of Majid and Poolak brands were 448.47 and 398.22 mg/kg, respectively. Additionally, the mean concentrations of lithium in canned tuna fish of Majid and Poolak brands were 38.42 and 39.67 mg/kg, respectively. The mean concentration of calcium in the investigated canned tuna samples fish was lower than provisional tolerable intake (PTI) per day (1000 ppm) set by World Health Organization (WHO) and Environmental Protection Agency (EPA). However, the mean concentration of lithium in the studied canned tuna fish samples was higher than PTI/day (0.650- 3.1 ppm) Set by EPA.

Conclusion: The results of current study showed that the marine food industries need a more-precise and serious monitoring by public health organizations. Additionally, protecting the marine environment from pollutions is an obligation that needs the attention of related organizations and authorities.

Effect of thermal modification temperature of spruce wood on cutting parameters during circular saw blade cutting
Authors: HLÁSKOVÁ LUĎKA , KOPECKÝ ZDENĚK , NOVÁK VÍT
Published: August 2021

Effect of thermal modification temperature of spruce wood on cutting parameters during circular saw blade cutting. The work examines the effect of temperature on energetical parameters (specific cutting resistance and cutting force) when cutting heat-treated wood of Norway spruce (Picea Abies) by a circular saw. The test samples were heat-treated at 160°C, 180°C, 200°C and 220°C. One sample was not heat treated and was used as a reference sample. In comparison with the theoretical assumptions, the influence of temperature on the cutting force and specific cutting resistance was confirmed. With increasing temperature of modification, the specific cutting resistance and cutting force decreased. The reduction of value of cutting force is related to changes in the chemical structure of the wood components, weight and density loss due to the increasing temperature of modification.
Effect of thermomechanical densification of pine wood (Pinus sylvestris L.) on cutting forces and roughness during milling
Authors: Białowąs Barbara , Szymanowski Karol
Published: August 2021

Effect of thermomechanical densification of pine wood (Pinus sylvestris L.) on cutting forces and roughness during milling. The paper presents the results of research concerning the assessment of machinability of pine wood thermomechanically compacted. The assessment was made on the basis of the cutting forces and surface roughness after the milling process. Selected properties of native and modified wood were examined. Based on the research, it was found that compacted wood is characterized by higher cutting forces during milling. The surface quality after milling was examined and the roughness index Ra values were determined. The research shows that the modified wood is characterized by a lower Ra value both along and across the grain. Statistical analysis showed that the modification had a statistically significant effect on the values of cutting forces and the physical and mechanical properties of the tested wood.
Influence of Traditional Wood Surface Modification Methods on Changes in Aesthetic and Resistance Properties
Authors: Różańska Anna , Sokołek Agnieszka , Barski Adam
Published: August 2021

For ages, furniture makers have been using various methods to accelerate the natural process of wood aging, in order to achieve a more sophisticated colour and to provide a uniform appearance for furniture parts replaced during restoration. Nowadays, wood aging is popular due to its aesthetic value associated with naturally aged wood, which can be enjoyed in conjunction with favourable mechanical properties of contemporary wood. Methods of wood surface modification used in wood aging can be divided into mechanical ones, consisting in changing the structure of wooden surfaces (eg. sanding, brushing, paint rubbing or structuring with chisel or other tools) and chemical ones, involving the use of chemical substances to change the colour of wood (eg. greying; application of lye, paint or wood stain; and ammonia fuming). The purpose of our study was to determine the influence of traditional wood modification techniques used in furniture-making − such as: structuring, whitewashing, rubbing, greying, dyeing with potassium permanganate solution and ammonia fuming − on the aesthetic and resistance properties of wooden surfaces (colour, gloss, roughness, abrasion resistance and resistance to scratches). Tests were performed on wood species most frequently used in Poland to produce artificially weathered wood: Scots pine (Pinus sylvestris L.) and common oak (Quercus Sp).
Strength comparative analysis of furniture joints made of various materials

Published: August 2021

The strength comparative analysis of furniture joints made of various materials. The influence of the load on the angular deformation of the furniture joint samples made of various materials was studied. The tests were carried out for six types of furniture materials: chipboard, MDF, hardwood plywood, glued pine wood, glued oak wood and HPL and for three types of fasteners with different ways of fixing in connected elements: shape-thread, expansion-expansion and expansion-thread way of anchoring in material of boards. The joint samples were loaded with a bending moment only (without inducing transverse loadings). The maximum load capacity and load capacity at the 3° (0.052 rad) sample rotation was measured and then the stiffness coefficients were calculated. Considerable differences were found between HPL and others lignocellulosic materials. Expansion fasteners offer incredibly low joint rigidity. This was observed for all tested furniture materials, from soft (chipboard) to very hard (HPL). Expansion connectors work better in soft lignocellulosic materials than in hard materials. The main advantage of expansion fasteners, in comparison to shape-thread fasteners, is its low visibility in the joint and the technological ease of assembly. On the other hand, thread-shaped connectors offer much greater strength and stiffness of joints.

Use of Recycled Asphalt
Authors: Thembeka Ncube Ayanda , Bobet Antonio
Published: August 2021

The term Reclaimed Asphalt Pavement (RAP) is used to designate a material obtained from the removal of pavement materials. RAP is used across the US in multiple applications, largely on asphalt pavement layers. RAP can be described as a uniform granular non-plastic material, with a very low percentage of fines. It is formed by aggregate coated with a thin layer of asphalt. It is often used mixed with other granular materials. The addition of RAP to aggregates decreases the maximum dry unit weight of the mixture and decreases the optimum water content. It also increases the Resilient Modulus of the blend but decreases permeability. RAP can be used safely, as it does not pose any environmental concerns. The most important disadvantage of RAP is that it displays significant creep. It seems that this is caused by the presence of the asphaltic layer coating the aggregate. Creep increases with pressure and with temperature and decreases with the degree of compaction. Creep can be mitigated by either blending RAP with aggregate or by stabilization with chemical compounds. Fly ash and cement have shown to decrease, albeit not eliminate, the amount of creep. Mechanical stabilizing agents such as geotextiles may also be used.

For this reason, firms may seek out employees with military backgrounds because they believe military training helps to shape ethical and disciplined habits. Several studies indicate military veterans may be less likely to engage in deviant behavior. However, other studies find deviant behavior is an extensive problem within the military. The purpose of this study is to compare the levels of minor workplace deviance between military and non-military organizations. In order to make this comparison,sample data from college football are utilized to compare on-field penalties—a proxy for workplace deviance. Results from an empirical model indicate that players with military training are less likely to engage in minor workplace deviance.

Disorders of Consciousness, Disability Rights and Triage During the COVID-19 Pandemic
Authors: Fins Joseph J. ,   Philosophy Documentation Center
Published: August 2021

As a member of the New York State Task Force on Life and the Law and the author of Rights Come to Mind: Brain Injury, Ethics and the Struggle for Consciousness, the author draws upon his work as a clinical ethicist during the COVID-19 Spring surge in New York to analyze the impact of ventilator allocation guidelines proposed by the Task Force on people with disorders of consciousness. While a non-discriminatory methodology was intended by the Task Force, the author concludes that the guidelines would have discriminated against people with disorders of consciousness had they been promulgated. This was due to errors in exclusion criteria, the utilization of the Sequential Organ Failure Assessment (SOFA) score, and the Glasgow Coma Scale which assesses motor output and not consciousness. While allocation and triage decisions may be neccessary during a pandemic, the ethical integrity of these determinations depend upon proper metrics.
Redefinition of the sexstrigatus group of Lasioglossum (Hemihalictus) Cockerell, 1897 (Hymenoptera, Apoidea, Halictidae), with a revision of Japanese species
Authors: Murao Ryuki
Published: August 2021

I propose a redefinition of the sexstrigatus group of Lasioglossum (Hemihalictus) Cockerell, 1897, including a phylogenetic analysis. This group is characterised by a combination of the following 12 characteristics: male antenna short, not attaining to metasoma, male labrum with distal process and well-developed basal elevation, male head with genal process as variation, female mesepisternum reticulate-punctate on lower area, mesepisternum without tubercle in both sexes, female metasomal terga with distinct fimbriae on posterior margin, male S8 with well-developed median process, gonobase ventral arm of male genitalia connected with each other at upper ends, gonocoxite of male genitalia smooth, gonostylus of male genitalia small and simple, bud-like, and the ventral retrorse lobe of male genitalia not attaining to gonobase. The Japanese species of the sexstrigatus group are revised. Thirteen species in total are recognised, including three new species: Lasioglossum (Hemihalictus) ikudomei sp. nov., L. (H.) spectrum sp. nov., and L. (H.) subsimplicior sp. nov. Lasioglossum (Hemihalictus) perplexans (Cockerell, 1925) is synonymised under L. (H.) kiautschouense (Strand, 1910). A key to the Japanese species is provided. Bionomical data, such as flight and flower records or habitat, are reported for some species. The distributions of all species are mapped. DNA sequences including a part of the barcode region are given for L. (H.) kiautschouense, L. (H.) ohei Hirashima & Sakagami, 1966, L. (H.) speculinum (Cockerell, 1925), L. (H. ) spectrum sp. nov., L. (H. ) subsimplicior sp. nov., and L. (H. ) taeniolellum (Vachal, 1903).
Study on Dynamic Positioning Capacity Analysis Method Considering Wind Shielding Effect of Offshore Structure

_

Offshore structures floating at sea should use their dynamic positioning (DP) system to maintain position and heading against environmental loads, including wave loads, current loads, and wind loads. It is difficult to calculate environmental loads accurately and quickly, especially for wind loads due to the shielding effect of different parts on offshore structures. To improve the accuracy of wind load calculation, a new method considering shielding effect is proposed. With the new method, calculated wind force becomes much closer to wind tunnel test than the traditional method. As input data of DP capacity analysis, the environmental loads have critical impact on the design of DP system. A static method and a time-domain simulation method of DP capacity are also proposed, and a case study of drillship is carried out. The results of both static analysis and time-domain simulation of DP capacity show that the new wind load calculation method has improved the accuracy of environmental load calculation and DP capacity analysis.

Introduction

As the offshore oil and gas exploitation is going further into deep sea, offshore structures are to be used in harsh marine environments, including strong wind, current, and waves. Especially for wind, it can make great effect on the dynamic positioning (DP) system of offshore structures, which is designed to maintain position and heading. Once the DP system is not able to keep the offshore structures’ position and heading, it will cause an accident such as oil leakage and oil pollution in the ocean. Because of the wind shielding effect among all parts on offshore structures, such as deckhouse, derricks, cranes, pipe racks, the wind load is difficult to calculate accurately and quickly.

Background:

Many individuals with multiple sclerosis (MS) depart the workforce prematurely. In the United States, access to insurance, including health, disability income, long-term care, and life insurance, is largely employment-based or purchased from earnings. Many individuals we see in the clinic experience financial hardship because of a lack of insurance, even if working. We sought to determine the proportion of workers who are financially protected through insurance coverage and the sources of this coverage in a large sample.

Methods:

We developed an online survey and opened it to individuals aged 18 to 65 years registered with the North American Research Committee on Multiple Sclerosis, iConquerMS, or the National Multiple Sclerosis Society Minority Advisory Council. Data collected included demographic and disease characteristics, current information about each insurance type (coverage vs no coverage), and when the current insurance policies were obtained relative to MS diagnosis.

Results:

Of 2507 survey respondents, 82.9% were female, 3.8% Hispanic/Latino, and 91.2% White. The mean ± SD age was 53.5 ± 8.5 years and disease duration was 16.4 ± 8.5 years after diagnosis. The most frequently held insurance types were health (96.3%) and life (58.8%). Only 9.7% of respondents had long-term care insurance. Except for life insurance, most current policies were obtained after MS diagnosis.

Conclusions:

Individuals with MS might not prioritize the possible short- and long-term benefits of these types of insurance. Health care providers can direct patients to nonprofit agencies that educate about of these insurance types and emphasize that others with MS have obtained these insurance types after their diagnosis.
Sustainable Preservation of Historic Buildings

Published: August 2021

Legal requirements as well as life quality requirements demand to increase energy efficiency of existing buildings, that has been seen to represent a huge potential in energy savings, based on the size of the segment and the individual potential. The biggest challenges during the renovation of buildings occur when it comes to historic buildings where the facade cannot be modified to maintain its unique architectural appearance and integrity. Policy makers and building owners are facing “building energy efficiency versus heritage value” dilemma when on the one hand it is important to preserve a building’s architectural value and on the other hand, energy consumption should be reduced significantly. Internal insulation is one of the energy efficiency measures that can be applied. However, this is one of the most challenging and complex energy efficiency measures due to changes in boundary conditions and hygrothermal behaviour of walls, especially for buildings in cold climate Applying of interior insulation significantly modifies the hygrothermal performance of walls and, as a consequence, may induce a risk on interstitial condensation, frost damage, mould growth and other damage patterns. The behaviour of internally insulated wall strongly depends on the properties of the used materials. There is a need to develop new methods and guidelines for decision makers on how to implement energy efficiency measures in historic buildings. The aim of this Thesis is to offer safe and effective solutions for internal insulation systems of historic masonry buildings. To achieve this goal, the following tasks have been set: to perform historic construction material testing and analyse the test wall in a laboratory environment to determine the factors influencing the accumulation of moisture and the risks associated with it; to predict hygrothermal conditions of internally insulated masonry building using dynamic simulation program and to validate said models based on long term in-situ measurements in internally insulated case buildings; to estimate potential energy savings using dynamic simulation program. Several methods are combined within the research, including regression analysis, sensitivity analysis and heat and moisture transfer simulation validated by long-term in situ measurements.
