Authors: Mejía Pardo Danny Sorel , Robles Romero Erika Rocio 
Published: June 2019

La presente investigación tiene como objetivo principal evaluar la calidad de aire con respecto a las partículas menores a 10 micras (PM10) en la ciudad de Trujillo, como parte de un estudio descriptivo de caracterización de la calidad del recurso aire.
Para lo cual, se tomó en cuenta las disposiciones y metodología establecidas en el Protocolo Nacional de Calidad del Aire y Gestión de Datos aprobado por la Dirección General de la Salud Ambiental – DIGESA, cuyos criterios permitieron ubicar en la ciudad de Trujillo 7 puntos de muestreo representativos para la medición de material partículado (PM10).
El muestreo de PM10 se realizó bajo el método de bajo volumen con el uso de un muestreador ambiental de polvo fino, Instrumex IPM-FDS 2.5µ/10µ, colectando la muestra por un periodo de 24 horas durante 3 días consecutivos para cada punto de muestreo. Para el análisis de la muestra se empleó el método gravimétrico, determinando para cada punto de muestreo, las siguientes concentraciones de PM10: Jirón Francisco Pizarro N° 412 es de 53.86 μg/m3; Av. Prolongación Vallejo s/n (Centro Recreacional la Rinconada) es de 78.19 μg/m3; Av. Salvador Lara Mz. R Lote - 34 es de 53.76 μg/m3; Av. Los Incas N° 405 es de 46.40 μg/m3; Av. Víctor Larco Herrera N° 13009 es de 69.95 μg/m3; Calle Sta. Teresa de Jesús N° 513 - Monserrate es de 23.28 μg/m3 y Mz. E Lote 17 - Urb. Los Jazmines es de 15.38 μg/m3.
Por lo tanto, de la evaluación realizada se concluyó que las concentraciones de PM10 en cada punto de muestreo se encuentran por debajo del Estándar de Calidad Ambiental para Aire (100 μg/m3) para un periodo de 24 horas según lo establecido en el Decreto Supremo Nº 003-2017-MINAM vigente al momento del estudió, por lo que la calidad del aire en la ciudad de Trujillo es aceptable; resultado contrario a la Evaluación, se halló para las concentraciones de PM10 para los puntos de muestreo del Jirón Francisco Pizarro N° 412; Av. Prolongación Vallejo s/n (Centro Recreacional la Rinconada); Av. Salvador Lara Mz. R Lote - 34 y Av. Víctor Larco Herrera N° 13009, los cuales superan la concentración umbral de PM10 (50 μg/m3) establecido por la Organización Mundial de la Salud (OMS – 2018).

Published: June 2019

En este trabajo se presenta el diseño, simulación e implementación de una dispensadora automática de bebidas “Barbot”, capaz de combinar diferentes tipos de bebidas (sodas, agua, licores) según el requerimiento del usuario mediante la programación de la misma el que luego se ejecutara de forma automática haciendo que el Barbot se desplace a la posición de cada botella que contiene el trago a combinarse activando el mecanismo dispensador de la botella en particular, repitiendo este proceso de forma automática hasta conseguir el trago deseado.
Los bares, restaurantes y centros de ocio, son medios muy concurridos por las personas para afianzar sus lazos familiares, amicales y sociales donde la presencia de bebidas, cocteles y diferentes tipos de tragos es de común consumo. En general y en especial en el Perú el servicio de Bartender suele ser manual, sin embargo este puede convertirse en un problema cuando la demanda de pedidos de tragos y cocteles es superior a la capacidad de producirlas por parte de los operarios o encargados de su elaboración, generándose cuellos de botella de producción que se traduce en pérdida de tiempo y posterior descontento en el cliente. Por otro lado, en entornos más privados suele darse el caso de desear una determinada bebida o coctel y no disponer del tiempo, conocimiento o los ánimos para elaborarla generándose con ello una frustración interna.
Una alternativa de solución a lo descrito previamente pasa por el desarrollo de una dispensadora automática de bebidas (Barbot) como un dispositivo asistente automático altamente reprogramable y de fácil uso, no requiere que el usuario tenga conocimientos especializados y permite obtener diferentes tipos de tragos y bebidas según la necesidad del cliente.
Primero, se implementa y calibra la estructura mecánico-eléctrica del Barbot. Segundo, se instalan, calibran y configuran los componentes electrónicos, el firmware, las herramientas de trabajo del Barbot. Tercero, se desarrolla un estándar de estructura lógica para los programas de la aplicación con el fin de garantizar un trabajo eficiente sin colisiones. Finalmente, se muestran diferentes resultados del trabajo del Barbot.

Published: June 2019

In the United States, Indiana ranks 43rdfor its infant mortality rate. Twenty-nine (of the 988) Indiana zip codes account for 27% of infant deaths. There is a need to train and mentor community members to lead local maternal and child health (MCH) efforts that address the priorities of community members as related to poor birth outcomes and facilitate the community’s solution strategies to this important public health problem. This community-centered approach coupled with local healthcare delivery helps thoroughly address local adverse birth outcomes. A comprehensive grassroots MCH leadership curriculum is needed for this training process. To meet this need we developed and solicited feedback on a curriculum designed to train community members situated in Indiana’s high-risk zip codes to be grassroots maternal child health leader (GMCHLs). The curriculum teaches GMCHLs the knowledge and skills to become self-reflective leaders who understand the causes and effects of adverse and inequitable birth outcomes, the negative health effects of chronic stress, and the protective power of the community. These GMCHLs will become skilled in the use of storytelling, Photovoice, policy development/advocacy and EvaluLead to build the capacity of their local community to support positive maternal and child health (MCH) outcomes.

Abstract
Background

Emergence of Extended Spectrum β-Lactamases (ESBL) among gram-negative bacteria, predominantly Escherichia coli in Nepal has been alarming. The main objectives of this study were to determine the prevalence of ESBL, ABL (AmpC type β-Lactamase), MBL (Metallo β-Lactamase) and KPC (Klebseilla pneumoniae carbapenamase) producing multi-drug resistant uropathogenic E. coli and their correlation with plasmid profiling pattern among the patients suspected of or having urinary tract infection in a tertiary hospital in Kathmandu, Nepal.

Methods

The mid-stream urine samples were collected from patients suspected of or having urinary tract infections (UTI) and were inoculated in Cystine Lactose electrolyte deficient (CLED) agar. The ESBL E. coli were detected by combined disc diffusion technique using cefotaxime with and without clavulanate. The isolates were screened for ABL by inhibitor-based method using cefoxitin alone and/or with cloxacillin. MBL/KPC were detected using combined-disc tests consisting of meropenem alone and with phenylboronic acid (PBA) or Ethylene diamine tetra acetic acid (EDTA), or both PBA and EDTA. Plasmids were extracted by alkaline lysis method from isolates and profiled on agarose gel electrophoresis.

Results

Out of total 2,661 urine samples, E. coli were isolated in 64.5% (507/788), among which 170 (33.5%) were MDR isolates. All MDR isolates were resistant to amoxicillin and third generation cephalosporins but were highly sensitive to imipenem (94.12%, 160/170), amikacin (92.94%, 158/170) and nitrofurantoin (86.47%, 147/170). Among 170 MDR isolates, 78.2% (133/170) were ESBL, 46.3% (50/170) were AmpC, 11.2% (19/170) were MBL and 0.6% (1/170) was KPC producers. Coproduction of β-Lactamases was detected in 24.12% (41/170) of isolates. E. coli isolates showed one plasmid (>33.5 Kb) which was unanimously present in all the isolates. Overall, 44 different plasmid profile groups were identified based on the molecular weight and number of plasmids. β-lactamase producers were relatively resistant to higher number of antibiotics (≤10) than non-producer (≤8) and number of plasmids were higher in β-lactamase producers (≤7) than non-producers (≤5).
Generation W: From the Young People’s Perspective
Authors: Jarić Isidora 
Published: June 2019

This paper discusses the position of young people in Ser­bia after October 5th 2000, as can be inferred from the evidence collected in the study ‘Politics and everyday life: Serbia 1999-2002’. The author identifies amongst young people four basic modes of self-positioning within the current social context, as de­scribed by the following labels: ‘B92 generation’, ‘provincials’, ‘fundamentalists’ and ‘guests’. These views encompass politics, their own social and political engagement, views of the future, and their own selves.
The Stuff of Christmas Homemaking
Authors: Vučinić Nešković Vesna 
Published: June 2019

The domestic burning of Yule logs on Christmas Eve is an archaic tradition characteristic of the Christian population in the central Balkans. In the fifty years following World War Two, the socialist state suppressed these and other popular religious practices. However, ethnographic research in Serbia and Montenegro in the late 1980s showed that many village households, nevertheless, pre­served their traditional Christmas rituals at home, in contrast to the larger towns, in which they were practically eradicated. Even in the micro-regions, such as the Bay of Kotor, there were observable dif­ferences between more secluded rural communities, in which the open hearth is still the ritual center of the house (on which the Yule logs are burned as many as seven times during the Christmas sea­son), and the towns in which only a few households continued with the rite (burning small logs in the wood-stove). In the early 1990s, however, a revival of domestic religious celebrations as well as their extension into the public realm has occurred. This study shows how on Christmas Eve, houses and churchyards (as well as town-squares) are being transformed into sacred places. By analyzing the temporal and spatial aspects of this ritual event, the roles that the key actors play, the actions they undertake and artifacts they use, I attempt to demonstrate how the space of everyday life is trans­formed into a sacred home. In the end, the meanings and functions of homemaking are discussed in a way that confronts the classic distinction between private and public ritual environs.
„Contested Identity“ of Macedonia: Identity of Difference
Authors: Stanković Pejanović Vesna 
Published: June 2019

Macedonia is still in the process of forging its identity as an independent state; a process that is “contested” not only sub-state national identities but also the extent to which Macedonia sees itself as a subject of international relations.Without the protection of the Yugoslav federation, Macedonia found its security weakened and as a response to Bulgarian and Greek attitudes a more assertive and uncompromising view of Macedonian nationalism emerged, which would have a significant influence on Macedonian-Albanian relations in the new state. The Macedonians saw their national identity “contested” from several directions at the beginning of the 1990s, most notably from Greece and Bulgaria, and from inside the new state the Albanian opposition to Macedonian political and cultural dominance. Internal challenge to national identity is a result of the large number of cleavages between the two main ethnic communities. Because of this society has become increasingly segregated with major tensions running through the formation of new political identities and institutions across ethnic lines.
External challenge to national identity between the Republic of Macedonia and its neighbors can be summarized as follows: Bulgaria is the main identity threat to the extent that identity is anchored in language; Serbs are the main identity threat to the extent that identity is anchored in religion; Albanians are the main identity threat to the extent that identity is anchored in statehood; and Greeks are the main identity threat to the extent that identity is anchored in the name of the nation, its language and state.
The Discourse of a Preschool Education Curriculum
Authors: Miškeljin Lidija 
Published: June 2019

The paper presents a critical analysis of the discourse of a preschool education curriculum. Its starting point is Foucault’s concept of discourse as language in use, which not only reflects the social order, but also shapes it through a network of conventions, knowledge and practices determining man’s – or, in this case, the reader’s – perception of reality.
The analysis is based on identifying the discourse strategies and/or systems of rules laid out in the text The basic principles of the preschool education curriculum for three- to seven-year-old children – model A which make possible certain statements and insights regarding children and thus position the child and the preschool teacher by means of discourse repertoires. This approach helps contextualize the text and leads to an understanding of the basic discourse mechanism involved in the creation of specific versions of preschool education.
As discourse analysis itself is related to interpretation and narratology, with the story as a constant, so is this paper a story about a preschool curriculum, for, like any other text, it tells an unfinished story that can yet evolve in different directions.

Published: June 2019

Abstract
Modified activated carbon/carbon nanotubes (AC*/CNT*) composite electrode was used as the electrode in a capacitive deionization (CDI) process for desalination in this study. The morphology and electrochemical characteristics of the modified electrode were discussed, and the results showed that after modification, the specific surface area of AC* reached 672.48 m2/g, increased by 29.43%; while the specific surface area of CNT* was 117.39 m2/g, reduced by 9.94% due to the strong oxidation of the mixed acid, the pore volume of CNT* increased by 48.28%. The electrode regeneration test proved that the electrode had good cycling stability. The pseudo-first-order kinetic model could better describe the adsorption rate of the electrodes for ions and the desalination ratio of the AC*/CNT* electrode reached 7.11 mg/g; the Langmuir model could well describe the adsorption mechanism of capacitive deionization, and indicated that the adsorption process of CDI was near to single ion layer adsorption; the change trend of electric mobility with migration time could be well fitted by exponential equations. This study explored a novel composite electrode coating, and initially explored the behavioral characteristics and trends of CDI technology.

AbstractIndustrial wastewaters and their treatment are now placed at the heart of the environmental concerns that industries face. Some research work has been carried out in order to limit the impact of these wastes on the environment as well as their costs. In this study, wastewater dehydrated sludge (55% wt. water content) from the paper industry was used to recover cellulose by using tetrakis(hydroxymethyl)phosphonium chloride, [P(CH2OH)4]Cl, ionic liquid as a solvent. The ionic liquid has shown remarkable results in terms of cellulose extraction in addition to its non-volatility and lower toxicity compared to organic volatile solvents. All cellulose, based on dry sludge, was recovered from the industrial dehydrated sludge with better operation conditions. The influence of temperature and the quantity of ionic liquid was preliminary studied in order to optimise the extraction conditions.
