W-band Low-Loss Eight-way Radial-Waveguide Power Divider Based on Coaxial Mode Transition
Authors: Song Kaijun , Zhu Lijuan , Li Qian , Fan Yong
Published: October 2022

A W-band eight-way radial-waveguide power divider with low insertion loss and high power-combining efficiency has been proposed in this paper. The coaxial waveguide has been utilized in the eight-way radial-waveguide power divider as a transition from the rectangular waveguide to radial waveguide. The structure of the coaxial mode transition from the rectangular waveguide to radial waveguide is simple and its electrical length is much shorter than others’ mode transition, which results a low insertion loss and high power power-combining efficiency. The microwave signal was input from the rectangular waveguide (TE10 mode) and transmitted to the radial waveguide (cylindrical TEM mode) through the coaxial waveguide (TEM mode). Finally, the signal in radial waveguide is divided into eight ways with equal power and equal phase by the eight output standard rectangular waveguide. To verify the presented power divider, a W-band eight-way power divider is fabricated and measured. The measured results show that, over the frequency range from 82GHz to 110GHz, the measured input return loss is greater than 15dB, the measured average insertion loss are about 9.4 ± 0.5dB, the phase imbalance is about ± 5°, and the power-combining efficiency is about 91%.

Authors: Tasseron Paolo , Begemann Finn , Joosse Nonna , Ploeg Martine van der , Driel Joppe van , Emmerik Tim van
Published: October 2022

Accumulation of plastic in aquatic environments negatively impacts ecosystems and human livelihood. Urban areas are assumed to the main source of plastic pollution in these environments, because of high anthropogenic activity. Yet, the drivers of plastic emissions, abundance and retention within these systems and subsequent transport to river systems is poorly understood. In this study, we demonstrate that urban water systems function as major contributors to river plastic pollution, and explore the potential driving factors contributing to the transport dynamics. Monthly visual counting of floating litter at six outlets of the Amsterdam water system results in an estimated 2.7 million items to enter the closely connected IJ river annually, ranking it among the most polluting systems measured in the Netherlands and Europe. Subsequent analyses of environmental drivers (including rainfall, sunlight, wind speed and tidal regimes) and litter flux showed no strong correlations (r = -0.19 - 0.16), implying additional investigation of potential drivers is required. High frequency observations at various locations within the urban water system and advanced monitoring using novel technologies could be explored to harmonize and automate monitoring. Once litter type and abundance are well-defined with a clear origin, communication of the results with local communities and stakeholders could help co-develop solutions and stimulate behavioural change geared to reduce plastic pollution in urban environments.

Abstract
Background: The α/β-hydrolase domain 2 (ABHD2) genes which was expressed in the alveolar type II cells (AT-II cells) have been identified as down-regulated genes in human emphysematous lungs. Meanwhile, ABHD2 is considered a triacylglycerol lipase. We investigated how the ABHD2 gene is involved in the development of emphysema by affecting lipid metabolism.
Methods: We treated A549 cells (whose biological characteristics were similar to those of AT-II cells) with/without ABHD2 knockdown at 0,50,100umol/L palmitic acid (PA). The cells were stained by Oil Red O, probe DCFH-DA, Annexin V-FITC/PI. The contents of intracellular triglyceride, MDA, Caspase-3 activity and cell viability were determined. We analyzed of C57BL6 and Abhd2 knockdown mice at different ages. The triglyceride, cholesterol and MDA level in mouse serum were measured. The contents of triglyceride, Malondialdehyde (MDA), Caspase-3 activity in mouse lung tissues were determined. The lung tissues were stained with hematoxylin and eosin, Oil Red O and TUNEL.
Results: We found that there were excessive deposition of triglyceride, lipid peroxidation, decreased cell viability and increased apoptosis in the cells with ABHD2 knockdown, showing lipid toxicity. At the same time, ABHD2 knockdown aggravates the lipid toxicity induced by PA in the A549 cells. ABHD2 deficiency resulted in abnormal lipid metabolism and lipid peroxidation in serum of mice. Meanwhile, these mice developed spontaneous gradual progression of emphysema, due to abnormal lipid metabolism, lipid peroxidation and enhanced apoptosis in lung tissues of ABHD2 knockdown mice.
Conclusions: Our findings suggest that ABHD2 knockdown can induce emphysema by accelerating triglyceride deposition.

Published: October 2022

Intensive care units (ICUs) are special hospital wards that provide desired treatment and close monitoring of patients who are critically ill. Drug Utilization Reviews (DUR) is an authorized, structured, ongoing review of patient medication to ensure appropriate and rational medication use to yield positive outcomes. The aim of this study is to evaluate the antibiotics and clinical outcomes in intensive care unit (ICU) patients. This study was cross sectional retrospective (cohort), descriptive and clinical study including patients admitted in ICU of tertiary care hospitals.A total 400 patients (Male 53%) and (Female 47%) were admitted in ICU were analyzed in this study. Majority of patients were from age group between 41 to 60 years i.e. 50.2%. Patients evaluated in this study were suffering from many diseases and comorbidities majorly including respiratory, infectious, nephrology and urology diseases. Antibiotics, majorly penicillins were administered to 185 (46.2%) patients, flouroquinolones 162 (40.5%), cephalosporins 287 (71.8%), carbapenems 102 (25.5%), vancomycin 61 (15.2%) and metronidazole 217 (54.2%) patients. Total 52 (12.5%) patients underwent Culture sensitivity test. Significant drug-drug interactions were seen in 64% patients. High mortality rate (72.8%) was seen in this study. It was observed that presence of NI and lack of CST enhanced mortality rate. CST is very important regarding choice of ICU patient’s antibiotic therapy.Current study identified factors affecting the clinical outcomes in terms of morbidity and mortality in the ICU patients. Antibiotics are prescribed in ICU abundantly. Due to presence of drug-drug interactions, nosocomial infections, comorbidities, not having culture sensitivity test (CST) and adverse reactions mortality rate was enhanced. Pharmacist led medication review will help in avoiding all these issues.

Published: October 2022

Wear of metallic surfaces after total knee arthroplasty is uncommon. In this case, we report a catastrophic failure of the knee prosthesis in a 60-year-old male patient who had undergone total knee prosthesis 7 years prior to his admission to our clinic. Genu recurvatum was observed in the affected knee. Surgical exploration of the knee showed wear of the polyethylene insert accompanied by metallic tibial component abrasion of the posterior-cruciate-retaining total knee prosthesis (Maxim, Biomet, Warsaw, IN, USA). Single-stage revision was performed, and a new total knee prosthesis was implanted (Legion, Smith & Nephew, Memphis, TN, USA). Postoperative examination showed improved stability and correction of recurvatum of the affected knee and follow-up examination showed improved weight bearing ability and better overall functional outcome.

Published: October 2022

The purpose of this study is to study two-dimensional CFD simulations of the COVID-19 virus two-phase flow in steady air with the Euler-Lagrange method. This was accomplished by developing CFD programs in MATLAB and simulations in COMSOL software. Brownian, drag, Saffman, and weight forces are considered for studying the dynamics of virus flow. In order to study the motion of viruses, Brownian, drag forces, and the weight of viruses play an important role. In this study, three different diameters of virus particles were considered, with three different initial conditions and three different initial velocities. The diffusion length and suspending time of viruses in the air have been computed in each of the nine states.

The Odesa Image in Odesa-Themed Restaurants
Authors: Dovgopolova Oksana
Published: October 2022

The popularity of Odesa-themed restaurants across the world presents an opportunity to explore a possible core of the Odesa city myth, sedimented into consumer space. The article analyzes 63 enterprises in seventeen countries, examining the cuisine, interiors, restaurant concepts, media reviews, and visitor reports on social media. The theoretical framework of this study revolves around the concept of memory entrepreneurship, the concept of travelling mnemonic plots, and instruments of marketing semiotics, especially the “cultural mélange” phenomenon. The surveyed restaurants reveal a specific picture of an Odesa “memoryscape,” formed as a dense palimpsest. The key themes are the motifs of an inverted world and of a lost Paradise. The plot of the Odesa myth in restaurants outside Odesa can be described as a temporal loop, starting at several points simultaneously, traversing the space of the world, then collapsing and returning to the departure time in a gesture of grief over the lost paradise.
Social Estates, Occupation, and HISCO: A New Study of Odesa in 1897
Authors: Brik Tymofii
Published: October 2022

Odesa was one of the largest and most important cities in the Russian Empire. Numerous studies have addressed the economic development and social structure of Odesa, but there are some gaps in the knowledge of the social stratification during the nineteenth century. Although most studies of the social and economic histories of Ukraine provide qualitative or highly aggregated quantitative data, micro-data at the level of individuals and households in Ukraine are rare. This paper provides new micro-data from the 1897 census in Odesa. It is the first attempt to code occupations of Odesa workers according to the Historical International Standard Classification of Occupations (HISCO). Of the 2,435 individuals in the 457 sampled households analyzed, 1,443 individuals demonstrate 86 of the unique occupations coded with the international HISCO scheme. The analysis compares these HISCO occupations by the social estates, the gender, and the language of the surveyed individuals. The study confirms several old hypotheses but also unearths new findings regarding the number of urban females involved in service and sales occupations.
Increased Leaching Requirements Allow the Use of Source Water High in Salts for Plant Growth
Authors: Moore Kimberly , Burgart Cristina , Shawaqfeh Samar , Fisher Luci , McMillan Mica
Published: October 2022

Growers have different capabilities to alleviate salt stress in the growing substrate. One method to reduce substrate salt levels is to increase the volume of water applied during irrigation. This increases the leaching fraction (LF) which is the volume of water that drains from the growing substrate divided by the volume applied during irrigation. We can determine the leaching requirement (the minimum LF to maintain a desired substrate salt level) using the formula LF = ECw/5(ECe − ECw), where ECw is the electrical conductivity (EC) of the water and ECe is the desired EC of the substrate. We tested this formula to see if we could maintain an acceptable substrate EC of 4 dS⋅m−1 by modifying the LF for ‘Hope’ philodendron (Philodendron selloum) and ‘Tineke’ ficus (Ficus elastica) irrigated with tap water (EC 0.17 dS⋅m−1) or reclaimed wastewater (RWW) from Davie, FL, USA (EC 1.66 dS⋅m−1) and RWW from Hollywood, FL, USA (EC 2.93 dS⋅m−1). Shoot and root dry weight was greatest for both species with the tap water applied with a 5% LF. Increasing the LF to 15% for Davie RWW and a 55% for Hollywood RWW, produced acceptable growth for ‘Hope’ philodendron and ‘Tineke’ ficus. In our second experiment, we monitored the growth of ‘Looking Glass’ begonia (Begonia fibrous), ‘Freddie’ calathea (Calathea concinna), and ‘Déjà vu’ philodendron (Philodendron selloum) irrigated with tap water (EC 0.15 dS⋅m−1), salt water (EC 3.49 dS⋅m−1), or RWW (EC 3.48 dS⋅m−1) with LFs of 28%, 50%, or 65%. ‘Looking Glass’ begonia and ‘Freddie’ calathea growth was greater with 65% LF than 28% LF, respectively, for all three water sources. Philodendron growth was not different due to LF. However, philodendron, calathea, and begonia growth was greater with tap water and RWW than with saltwater. Although final leachate EC with saltwater and RWW was around 2 dS⋅m−1 using 50% LF, leachate sodium (Na) levels from salt watered plants was higher than for RWW or tap watered plants. We suspect that high Na levels in combination with lower potassium (K) and calcium (Ca) levels in the saltwater solution resulted in poor plant growth. Although the Na levels in leachate from RWW substrates was higher than tap watered substrates, Ca and K levels also were greater. Although we were able to use the salt equation to maintain substrate EC levels ranging from 2 to 4 dS⋅m−1, volumes of solution applied were two to three times higher when using RWW or salt water compared with tap water. We suspect that a balance between Na, Ca, and K supported better plant growth with RWW than salt water. However, additional work needs to be done on the benefits of supplemental Ca and K when using water high in salts or Na. This works suggests that in addition to monitoring EC, it also is important to monitor Na, Ca, and K concentrations.
Wave vector and field vector orientation dependence of Fe K pre-edge X-ray absorption features in clinopyroxenes
Authors: Steven Cody J. , Dyar M. Darby , McCanta Molly , Newville Matthew , Lanzirotti Antonio
Published: October 2022

Pre-edge X-ray absorption features are commonly used to derive redox states for transition metal oxides in crystals and glasses. Several calibrations for Fe2+ and Fe3+ in silicate glasses have utilized the general relationships among pre-edge peak intensity, energy, and redox state. However, absorption variations complicate those relationships in anisotropic crystals. Although absorption anisotropy at and above the energy of the rising edge adheres to the typical cos2 relationship observed in absorption spectroscopies at other energies, the anisotropy of the pre-edge is far more complicated. Prior studies focusing on pre-edge absorption anisotropy demonstrate a 1-cos4φ dependence of absorption magnitudes with rotation. Experiments presented here show that absorption magnitudes of the pre-edge vary as a function of both electric field vector orientation and wave vector direction. However, rotations around the field vector axis or wave vector axis individually result in cos2 dependence of absorption magnitudes. Rotations where both wave vector and field vector orientation are varied are not well fit by either model in the pre-edge. The resulting anisotropy complicates the process of measuring characteristic absorption in the pre-edge, making valence state determinations challenging for strongly anisotropic crystal structures such as pyroxene.

Effect of Isomerization and Copolymerization of Itaconic Anhydride During the Synthesis of Renewable Monomers Using Vegetable Oils
Authors: Gaglieri Caroline , Alarcon Rafael , de Moura Aniele , Magri Raquel , Rinaldo Daniel , Bannach Gilbert
Published: October 2022

Vegetable oils are alternatives to producing renewable monomers since they are biomass. It is possible to react them with anhydrides by heating to provide monomers with high reactivity. However, after the reaction of grape seed oil with itaconic anhydride, it was observed the occurrence of parallel reactions that had not been observed when the same oil was reacted with maleic anhydride. Some articles in the literature have reported that temperature and bases can isomerize itaconic anhydride into citraconic anhydride, which is more stable at room temperature. However, they have not focused on completely understanding how this phenomenon occurred nor studied it in processes that involve microwave irradiation. Therefore, this paper presents a complete characterization and investigation about the thermal behavior of itaconic anhydride and how it can affect the monomer synthesis performed under heating.
Sugarcane Bagasse Fibers Derivatives and Their Application in Chitosan-Based Composite Films for NPK Fertilizer Release
Authors: Messa Lucas Luiz , Contieri Gabriela Aparecida , Faez Roselena
Published: October 2022

Encapsulation and release of NPK fertilizer by composite films were systematically demonstrated by casting dispersions of chitosan (CS) and sugarcane bagasse (SCB) derivatives (holocellulose (HC), cellulignin (CL), and cellulose (CEL)) fibers under varied CS-to-NPK and CS-to-SCB derivatives mass ratios. SCB derivatives were obtained from sugarcane bagasse as agricultural waste by following the alkali dissolution (4% NaOH, 70 °C for 5 min), sodium chlorite delignification (1.4% NaClO2, pH 3.5, 70 °C, 5 h), or from a combination of both. Nutrientadsorption capacity can be tunable by the chemical composition of SCB derivatives, i.e., fibers with noncellulosics exhibited higher adsorption capacities while the absence of noncellulosics lessened their adsorption capacity. Oven-drying (60 °C, 5 h) of optimal 1:0.5 CS/NPK film‑forming solution produced highly uniform films with shape with 0.31 ± 0.02 mm thickness while increasing fiber content in the solution to 25 or 50% prevents films retraction effect. The release of highly watersoluble NPK fertilizer from these composite films was lower with hemicelluloses (52-82%) or lignin (55-92%) contents in SCB fiber than in noncellulosics absence (71-100%), thus could be tuned by varying the chemical composition SCB derivative, followed by a quasi-Fickian diffusion mechanism in water.

Published: October 2022

Drought assessment and monitoring are essential for its proper management. Drought indices play a fundamental role in this. This research introduces the Wet-environment Evapotranspiration and Precipitation Standardized Index (WEPSI) for drought assessment and monitoring. WEPSI incorporates water supply and demand into the drought index calculation. WEPSI considers precipitation (P) for water supply and wet-environment evapotranspiration (ETw) for water demand. We use an asymmetric complementary relationship to calculate ETw with actual (ETa) and potential evapotranspiration (ETp). WEPSI is tested in the transboundary Lempa River basin in the Central American dry corridor. ETw is estimated based on evapotranspiration data calculated using the Water Evaluation And Planning (WEAP) system hydrological model. To investigate the performance of WEPSI, we compare it with two well-known meteorological indices (Standardized Precipitation Index and Standardized Precipitation Evapotranspiration Index), together with a hydrological index (Standardized Runoff Index), in terms of statistical metrics and mutual information (MI). We compare WEPSI-derived droughts and historical information, including crop production, cereal yield, and the Oceanic Nino Index (ONI). Results show WEPSI has the highest correlation and MI, and the lowest deviation. It is consistent with the records of the crop production index, cereal yield, and the ONI. Findings show that WEPSI can be used for agricultural drought assessments.
Tetracycline degradation by nonthermal plasma: removal efficiency, degradation pathway, and toxicity evaluation
Authors: Ouzar Amina , Kim Il-Kyu
Published: October 2022

Tetracyclines (TCs) are often discussed as one of the emerging contaminants detected in water matrices and studied for their persistence towards conventional water treatment technologies. In this work, the treatment of TC in aqueous solutions with nonthermal plasma gliding arc process was investigated. The degradation efficiency of TC was studied along with the effect of initial concentration, working gas, pH, and the presence of a radical scavenger. The generation of reactive oxidative species was characterized by the quantification of radical hydroxyl, hydrogen peroxide, ozone, nitrite, and nitrate. Mineralization efficiency was examined by assessment of Total organic carbon evolution. Experimental results have shown that the gliding arc plasma is effective for the treatment of TC. At an initial concentration of 5 mg/L: degradation rates of 94.95% and 60.45% were achieved, while mineralization rates were 81.3% and 57.34% under O2 and air plasma, respectively. O2 plasma exhibited an immense potential for the generation of reactive oxygen species. Meanwhile, air plasma showed better degradation performance in the presence of a radical scavenger. Moreover, degradation products were identified by mass spectroscopy analysis and degradation pathway was proposed. The gliding arc process proposed in this work is promising for the removal of TC antibiotics.

Authors: Lan Jingming , Wang Baoying , Gong Bolin
Published: October 2022

In this study, activated carbon (AC) was chemically activated using sodium hydroxide (NaOH), and polyethyleneimine (PEI) was grafted onto the AC using glutaraldehyde as a cross-linking agent. Then the modified AC was applied to treat water samples containing copper ions (Cu2+). Preparation of AC-NaOH@PEI. The grafted AC was characterized, demonstrating that the specific surface area of material decreased from 959.3 to 556.9 m2/g. The ζ-potential changed from −27.2 to 10.4 mV, and the presence of a distinct flocculation on the surface of the AC was observed via scanning electron microscopy. The results demonstrated that PEI was successfully grafted onto the surface of AC. Furthermore, the adsorption results indicated that the Cu2+ adsorption capacity of AC-NaOH@PEI was greatly enhanced with increasing PEI loading. The adsorption amount of Cu2+ by the grafted AC-NaOH@PEI-200 increased from 20.02 to 47.8 mg/g. In addition, the adsorption of Cu2+ by AC-NaOH@PEI was a pH dependent process. At a pH of 6, the maximum removal rate reached 93%. The adsorption process is better described by the Langmuir and quasi-second order adsorption models, signifying that the adsorption of Cu2+ on AC@PEI consists of monolayer adsorption and chemisorption. After four adsorption-desorption cycles, AC@PEI exhibited high adsorption capacity for Cu2+, indicating that it has good regeneration ability. It is a promising adsorbent material.
Electrochemical reduction of Cr (VI) using a palladium/graphene modified stainless steel electrode
Authors: Ma Wenqing , Liu Yubo , Zhang Shaohui
Published: October 2022

In this study, a palladium/graphene modified stainless steel electrode was successfully prepared and applied in an electrochemical reduction device to remove Cr (VI) from the wastewater. Pd was modified onto the electrode mainly via interacting with the carboxyl group of graphene. The Cr (VI) removal efficiency was up to 99.70 ± 0.00% under the optimal condition (Pd content proportion of 3%, electrode potential of −0.9 V, pH = 2 and electrolyte concentration of 6 g/L). It was found that Cr (VI) was removed via the following processes: (1) direct electrochemical reduction by accepting electrons, (2) indirect electrochemical reduction by H2O2 that was generated from H2 in the presence of Pd, (3) adsorption through hydrogen bond, and (4) chemical reduction through alkoxy groups donating electrons. The indirect electrochemical reduction considerably promoted the Cr (VI) removal while a small amount of Cr (VI) was removed via adsorption and chemical reduction. The method could not only be used as a pretreatment technology to solve the problem of excessive Cr (VI) concentration of industrial wastewater, but also could provide reference for the electrochemical reduction of similar metal ions.

Published: October 2022

Channels and sewers are commonly used to collect sewage during extensively rural areas. The sewage and bacterial characteristics of rural sewage collection systems can influence their operation and maintenance performance which further affect appropriate system decision. In this study, eight rural sewage collection systems (four each of channels and sewers) were applied to evaluate the sewage quality, bacterial characteristics, and their differences of two kinds of collection systems. The results indicate that significantly distinction existed between the rural sewage collection systems of channels and sewers. Sewage in channels had higher suspended solid (SS) concentration but lower sulfide concentration than that in sewers. The SS, sulfate, and chemical oxygen demand (COD) removal capacity in channels was nearly 3.5, 4.0, and 0.6 times than those in sewers. At least 14 genera and 18 species of bacteria showed significantly distinction between channels and sewers even their main phylum, genus, and species of bacteria communities was Proteobacteria (∼70.3%), Acinetobacter (∼22.3%), and Pseudomonas fragi (∼13.8%), respectively. The structural characteristics and bacterial function caused the difference between channels and sewers. Overall, this study revealed the intrinsic and essential differences of channels and sewers, providing basic and meaningful data for rural sewage collection systems decision.
Deep aquifers as strategic groundwater reservoir in Spain

Published: October 2022

The objective of this paper is to establish a definition of deep aquifers, develop a methodological proposal to help select them as strategic groundwater reserves and develop a first inventory of deep aquifers in peninsular Spain, organized by hydrographic districts. The basic premises followed to consider a permeable formation as a deep aquifer are: water table depth greater than 300 m in free aquifers or the top of the permeable formation in the case of confined aquifers. A deep aquifer is also considered to be the lower horizon of very thick aquifers (from 300 m), from which the most superficial horizon is used. The definition of the potentially favorable areas and the initial characterization is based on a compilation and synthesis of geological and hydrogeological information, structured in 5 large blocks: location and identification, geology, hydrogeology, current status and bibliography. For its evaluation, a flowchart has been proposed with the basic lines of the evaluation process. The relevant aspects for suitability would be: stratigraphy and structural geology, prior knowledge of the conceptual model and water renewal, quality, viability of exploitation, effects, final knowledge, and management and governance. The final result allows the aquifer to be classified into three categories: strategic groundwater reserve, punctual reserve or non-viable reserve. The inventory carried out encompasses a total of 64 deep aquifers located in 13 basin districts. Finally, as example, three deep aquifers are presented: Amblés Valley, Madrid detritic aquifer and El Maestrazgo.
Extrema-direita, xeno-populismo e colonialidade: discursos de ódio e colonização do imaginário no presente
Authors: Severo Denise Osório , Guerra Paula
Published: October 2022

The expansion of far-right movements constitutes a global phenomenon that has translated into the emergence and strengthening of numerous organizations, parties, and especially into the conquest of power in many countries in Europe, North America, and Latin America. In this article we will try to account for this phenomenon, first by presenting and reflecting on the different theoretical conceptions that have been held about it, namely the different related concepts used by academia, such as populism, fascism, extreme right or authoritarian neoliberalism. On a second level, we will focus our attention on Poland and Portugal. In the case of Poland, for its admittedly populist conjunctural character, ruled since2015 by the Law and Justice Party. In the case of Portugal, for its opposite character, under the management of the Socialist Party, recently reelected with 60% of the votes, but which also experiences the strengthening of extreme right-wing movements. Respecting the sociocultural and historical particularities of each, in both countries these movements are expressed both in civil society and in political society. These experiences reveal counterfaces that, despite their differences, signal approximations with the xeno-populist perspective and can shed light on the understanding of these processes. In the Polish scenario, the adoption of institutional policies and legislation against migrants, LGBTQIA+ and other minorities are notable, as well as growing manifestations of far-right movements, both based on hate speech. On the other hand, the Portuguese context, although governed by an opposite political spectrum, also experiences recent processes of strengthening of the far right. In fact, the far-right "Chega" party won third place in a recent election marked by tensions involving hate speech, xenophobia and nationalist perspectives

Para categorizar las patologías de los elementos líticos y diagnosticar el nivel del daño existente ocasionado por los agentes extrínsecos e intrínsecos en las fachadas de la Iglesia Basílica Catedral y de la Compañía de Jesús, se aplicó el enfoque mixto de nivel descriptivo transeccional a través de la observación directa. Fueron registradas siete patologías líticas clasificadas en el grupo de mecánicas (disgregación, grietas, fragmentación, perforación, faltantes, estallidos y erosión). Las patologías son de origen mecánico en ambas fachadas y se ha logrado diagnosticar que la disgregación es la patología con mayor impacto y frecuencia. Ambas iglesias padecen las mismas patologías debido a que comparten la misma tipología de roca y estan expuestas a las mismas condiciones medioambientales. Sin embargo, el nivel de agresión que presenta cada una de ellas es diferente.
“Los Grupos-patio”: un tipo de organización espacial al interior de un asentamiento del Período Intermedio Tardío (1100-1400 D.C) en la provincia Vilcas Huamán
Authors: Martinez Sulca Winnie Celeste
Published: October 2022

El estudio arquitectónico realizado, a través del levantamiento planimétrico y topográfico, en el sitio arqueológico Llaqtaqasa, específicamente en el sector B, arrojó nuevos datos sobre los “grupos-patio”, los cuales, además de ser la unidad constructiva arqueológica registrada, corresponden a un nuevo tipo de organización espacial al interior de un asentamiento del periodo Intermedio Tardío en la provincia de Vilcas Huamán (Ayacucho). Esta organización presenta una configuración espacial cerrada donde los recintos y patios son los principales componentes. Este artículo presentará los datos obtenidos en torno a este tipo de organización espacial donde se está considerando además las distintas fases constructivas y la circulación interna en el referido sector.
Historia y cambio de uso de la casa de Bolognesi
Authors: Barrera Camarena Henry
Published: October 2022

La casa de Bolognesi es el reflejo no solo de una típica casa republicana de inicios del siglo XX, también trae al recuerdo a uno de los más importantes héroes nacionales, el coronel Francisco Bolognesi Cervantes, y junto a él los peruanos que dieron sus vidas en la batalla de Arica (1880). Por esa razón, a través de esta investigación se busca rescatar el devenir de la casa hasta el momento en que su uso es cambiado, es decir, pasó de ser un espacio que albergaba familias (uso privado) a uno que simbolizara y resguardara la memoria de los combatientes de Arica (uso público), el Museo de los Combatientes del Morro de Arica.Asimismo, se analizará cómo el desarrollo urbano de Lima casi significó el derrumbe de este monumento histórico. La proyección de la avenida Santa Rosa en la década de 1940, la cual se pretendía con el ensanche y la prolongación del pasaje que lleva el mismo nombre, para regular el tránsito vehicular necesitaba, para su ejecución, destruir una serie de casas que se interponían en su camino, entre ellas la casa de Bolognesi.
Orígenes de los museos universitarios del Perú. Gestiones, tensiones y motivaciones fundacionales
Authors: Hurtado Castro Hernán Iván
Published: October 2022

Las nuevas tendencias museológicas globales, como ecomuseos, museos digitales, museos comunitarios, entre otros, repercuten también en el diseño y ejecución de los museos universitarios y sus manejos de colecciones. Ello es una permanente tensión institucional, sea esta económica, de infraestructura, de gestión, de especialización, de su concepción misma y de su función en tanto corresponde al rol de la universidad en la sociedad.Entonces, el presente texto ensaya ser un yacimiento genealógico del museo universitario en el Perú, desde una revisión de las tensiones y motivaciones fundacionales de algunos casos de museos en relación con la titularidad de sus universidades, y el tránsito hasta las instituciones museables contemporáneas. Por lo tanto, en el proceso institucional dentro de la fundación y desarrollo de la república y con la idea de nación también se van importando o prestando diseños, comportamientos e imágenes institucionales en la concepción de un museo tutelado por una institución de educación superior, esto es, dicho de otro modo, un museo universitario.
Apuntes teóricos sobre el patrimonio arqueológico prehispánico en Lima. El caso Garagay
Authors: Becerril Cotera Eduardo Martín
Published: October 2022

Lima es una ciudad donde el área de sitios arqueológicos supera a las áreas verdes. El reto de afrontar dicha realidad para preservar y recuperar nuestros monumentos es enorme; para ello es necesario evaluar la teoría con la cual nos enfrentamos a dicho reto. La presente Ninvestigación propone un marco teórico basado en diversos aportes conceptuales sobre el  modelo territorial prehispánico y su devenir en el tiempo. Además, busca contraponer los enfoques de gestión como la puesta en valor y el uso social para evaluar su pertinencia en el contexto actual de los sitios arqueológicos en Lima, su relevancia en la ciudad y su proceso de patrimonialización. Por último, analiza el caso de Garagay y sus dinámicas urbanas para entender su relevancia en la ciudad y los conceptos de patrimonialización afines.

Autobioetnografía de una mujer en una organización pública en el área de seguridad
Authors: Caicedo-Muñoz Silvia , Alarcón Tabares Laura Sophia
Published: October 2022

La mujer ha sido estudiada en las organizaciones del ámbito de la seguridad y convivencia desde 1950, según la literatura del management. Progresivamente, las políticas de género, en Colombia, han posibilitado el ingreso de las mujeres a ese ámbito. Este artículo describe autobioetnográficamente cómo una mujer desde su toma de decisiones y sus emociones participa en una organización policiva. El hallazgo más significativo es que existe una genderización de la organización pública, a pesar de las políticas de género.

Comics As a Tool for Research on Gender Violence. Interview With Nayanika Mookherjee on the Graphic Novel Birangona. Towards Ethical Testimonies of Sexual Violence During Conflict (2019)
Authors: Mandolini Nicoletta , Mookherjee Nayanika
Published: October 2022

Comics and the recently emerged graphic novel format are among the art forms that researchers have chosen to disseminate and provide a visual representation of their work. This relationship between comics and research, which is part of a practice labelled as “arts-based research”, has been facilitated by comics’ recognised narrative and didactic abilities. Research on gender-based violence has not been deaf to the call of comics art, and, in some rare but interesting cases, it has exploited the features of the medium to visualise and circulate research findings. An example is the graphic novel Birangona (Mookherjee & Najmun Nahar, 2019 Durham University), authored by the researcher Nayanika Mookherjee and by the comics artist Najmun Nahar Keya, which was circulated, both in an online and paper version, with the aim of popularizing a set of guidelines on how to conduct oral history data collection with survivors of wartime rape. This interview with Professor Nayanika Mookherjee, the co-author of the graphic novel and the anthropologist who conducted the research with wartime rape testimonies from which the guidelines were taken, has the objective of presenting the arts-based research project Birangona and discussing, in a scholarly fashion, the implementation of visual arts methodologies (and comics-based methodologies in particular) to research gender violence.
Assessing effectiveness of teaching practice towards quality preparation of preservice technical teachers
Authors: Olabiyi Oladiran Stephen
Published: October 2022

The study assesses effectiveness of teaching practice towards quality preparation of preservice technical teachers for the world of work considering support received from cooperating teachers vis-à-vis: planning/development of lessons, classroom management/control, professional personality/responsibility, teaching skills, number of periods and challenges confronting preservice teachers, were investigated. The study adopted a descriptive survey research design. Data were obtained using a structured questionnaire from the sample of 82 preservice technical teachers. The collected data were analyzed using mean, standard deviation, independent sample t-test and ANOVA to test hypotheses at 0.05% level of significance. The study found that supports and training have positive impacts on preservice technical teachers with vis-a-vis training domains towards quality preparation. However, the study shows that gender and school type does not influence preservice technical teachers’ perception regards to support and training. Consequently, the study recommended that schools administrators and cooperating teachers should increase acceptability and guidance of preservice teachers, work out modalities with institutions to ensure quality preparation of teachers for the world of work, challenges identified should be taken care of to improve preservice teachers’ competence
Investigating basic channel routing matrix using reaper: designing a surround sound 5.1 instruction model for learning
Authors: Anwar Ardy Aprilian , Afif Riky Taufik , Padil Md Nagib Bin
Published: October 2022

The production and processing of surround sound are only done in the post-production department for movie and home theaters. In our country, there has been no specific teaching on surround sound systems, especially in channeling. We use matrix routing to define the DAW's channel flow arrangement on the soundtrack. Surround Sound spatial sound processing is indispensable for improving film production in Indonesia. Inspired by Dolby Surround, we independently investigated the matrix channeling on the Reaper DAW to identify the specific settings for getting ready audio mixing conditions with a 5.1 surround system. Specific tools are needed to understand large and complex data sets to understand processes. We went through several experiments and time to understand this, collecting observational data through recording and thinking hard until finally, we poured the process into a model of teaching materials. We offer channel patching on some audio interfaces. The design of teaching materials implemented the findings of this study. Furthermore, the teaching material model can be equipped, used, and adjusted to the conditions of the place of study.
