Increasing Labile Soil Carbon and Nitrogen Fractions Require a Change in System, Rather Than Practice
Authors: Diederich Kalyn M. , Ruark Matthew D. , Krishnan Kavya , Arriaga Francisco J. , Silva Erin M.
Published: November 2019

The influence of tillage, carbon (C) and nitrogen (N) inputs and perennialization on labile fractions of soil organic matter (SOM) has been widely investigated, but research on the temporal and depth variation of labile C and N fractions in long‐term agroecosystems representative of the US Corn Belt is lacking. In this study, labile soil fractions as influenced by different agriculture management approaches common in the north‐central United States were characterized through measurements of potentially mineralizable N (PMN), mineralizable C (C‐min), and permanganate oxidizable C (POXC), which are known indicators of the biologically active pool of SOM. Soils were sampled five times in six different cropping systems at the Wisconsin Integrated Cropping Systems Trial: three annual cropping systems (continuous corn, strip‐till corn–soybean, organic grain) and three forage cropping systems (conventional forage, organic forage, grazed pasture). Across all sampling dates (May–September) and soil depth (0–15 and 15–30 cm), forage‐based cropping systems generally had greater PMN, C‐min, and POXC, with C‐min and PMN expressing the largest differences between forage and grain‐based cropping systems. Labile soil C and N fractions across cropping systems were typically greatest in July or August and were ∼50% greater in the top 0 to 15 cm of soil than the 15 to 30 cm. These results suggest sampling timing and depth for PMN, POXC, and C‐min need to be standardized to optimize their use as soil health indicators and that shifts in the system toward perenniality will be required to increase labile C and N fractions on the highly fertile Mollisols of the US Corn Belt.

La exposición a situaciones de vulnerabilidad y violencia, como el desplazamiento forzado, generan en la población víctima efectos nocivos para su salud mental. El objetivo del presente estudio es describir el estado actual de la salud mental y algunos factores sociodemográficos y del entorno asociados, de 471 adolescentes y jóvenes entre 13 y 28 años, víctimas de desplazamiento forzado en tres ciudades colombianas. Se aplicó la entrevista Composite International Diagnostic Interview (CIDI), versión CAPI (Computer Assisted Personal Interview); un cuestionario ad hoc sobre aspectos del desplazamiento forzado y el consumo de sustancias psicoactivas; la escala de funcionamiento familiar APGAR y la escala MOS (Medical Outcomes Study) de apoyo social. Se encontró una prevalencia de cualquier trastorno mental en el último año del 24,4% y cualquier trastorno por uso de sustancias del 4,7%. Los trastornos más prevalentes fueron fobia específica (6,8%), trastorno por estrés postraumático (5,7%) y trastorno depresivo mayor (5,1%). La dependencia a la marihuana se presentó en 2,1% de los participantes y el abuso de alcohol en 1,9%. Un 14,6% de los adolescentes y jóvenes víctimas de desplazamiento forzado han pensado suicidarse alguna vez en la vida. Ser hombre, menor de edad, con buen funcionamiento familiar y apoyo social adecuado, fueron factores protectores para la presencia de trastornos mentales.

Authors: Plascencia de la Torre Juan Carlos , Chan Gamboa Elsy Claudia , Salcedo Alfar José Manuel
Published: November 2019

Objetivo: El presente estudio tuvo como objetivo evaluar los niveles de adherencia al tratamiento antirretroviral, así como determinar los factores psicológicos predictores de la no adherencia a dicho tratamiento en pacientes con VIH-SIDA. Método: Diseño descriptivo, transversal y correlacional. La muestra estuvo conformada por 25 personas diagnosticadas con VIH-SIDA que asistieron a los servicios integrales de una asociación civil en la ciudad de Guadalajara, México, y que se encontraban bajo tratamiento antirretroviral. Se utilizó el Cuestionario de adherencia al tratamiento para el VIH-SIDA [CAT-VIH] y el Cuestionario de Factores Relacionados con la Adherencia al Tratamiento para el VIH/SIDA (CFR-AT VIH). Se realizaron análisis descriptivos y no paramétricos para la comparación de las variables de estudio, así como sus respectivas correlaciones. Resultados: Solo 60% de los evaluados presentan una adecuada adherencia al tratamiento con antirretrovirales; además se encontraron diferencias significativas entre adherentes y no adherentes en las variables de autoeficacia (Z=-3.196; p=.001); estrés (Z=-2.033; p=.042); y depresión (Z=-2.409; p=.016). Se obtuvieron correlaciones positivas de la adherencia con autoeficacia (r=.750; p=.000) y apoyo social (r=.462; p=.020) y correlaciones negativas con estrés (r=-.543; p=.005) y depresión (r=-.544; p=.005). Conclusiones: A mayores estados de estrés y depresión, menor serán los niveles de adherencia al tratamiento con antirretrovirales; por lo cual estas variables deben ser tomadas en cuenta para el diseño de estrategias de mejora de la adherencia en personas con VIH-SIDA.
Comparison and optimization of the performance of natural-based non-conventional coagulants in a water treatment plant
Authors: Kaji Atefeh , Taheriyoun Masoud , Taebi Amir , Nazari-Sharabian Mohammad
Published: November 2019

This study aims to assess the efficiency of two natural-based coagulants, namely calcium lactate and tannic acid, and compare them with conventional coagulants, including polyaluminium chloride (PACl) and ferric chloride. Jar test experiments were performed on the raw inlet water of the Isfahan water treatment plant (IWTP) in Iran. Response surface methodology was implemented to design and optimize the experiments. The factors considered in the design were coagulant dose, pH, initial turbidity, and temperature. Results showed the acceptable efficiency of natural coagulants in turbidity reduction, so that they meet the potable standard levels. The final water turbidity in the optimum condition for calcium lactate, tannic acid, PACl, and ferric chloride were 0.58, 0.63, 0.56, and 0.76 NTU, respectively. The comparison between the performances of the coagulants showed no significant difference in turbidity removal. However, the sludge volume produced as well as the impact on pH alteration after coagulation–flocculation were lower when using natural coagulants than with conventional coagulants. Also, the residual aluminum for PACl measured was higher than the desired limit according to Iran's drinking water standard. Finally, the simple additive weighting method was used to rank the four coagulants based on the selected criteria. The results showed that the natural coagulants could be preferable to the conventional coagulants if the concerns regarding disinfection by-product formation due to their residual organics were resolved. Since this issue was fixed in the IWTP due to the ozonation process, calcium lactate was proposed as an efficient alternative to PACl.

Spirulina maxima L-asparaginase: Immobilization, Antiviral and Antiproliferation Activities
Authors: Abd El-Baky Hanaa H. , El-Baroty Gamal S.
Published: November 2019

Background:

L-asparaginase (L-AsnA) enzyme has gained significant attention in the
food, biocatalysts and pharmaceutics industry. It (L-AsnA) has been widely used in food processing
industries as a promising acrylamide mitigating agent and as a therapeutic agent in the treatment
of certain human cancers.

Objective:

Based on US Patent (4,433,054; 1984), L-asparaginase (L-AsnA) enzyme is immobilized
by admixing the active enzyme on the polysaccharide to be in a gel form. The storage stability
of immobilized L-AsnA enzyme and its anti-proliferation and antiviral activity were determined.

Methods:

In the present study, S. maxima was cultured at large scales (300 liter) for the production
of enough extracellular L-asparaginase (L-AsnA) using modified (high N concentration) Zarrouk
medium as we reported in a previous study. L-AsnA was immobilized on natural polymers,
as agar cake beads, agarose pieces and gelatin blocks, in order to evaluate the efficiency of physical
entrapment techniques. Anti-proliferation properties of L-AsnA against lung carcinoma A549,
hepatocellular carcinoma Hep-G2 and prostate carcinoma PC3 human cancer cell lines were assessed
by the MTT cell viability method. In addition, the antiviral activity against Coxsackie B3
(CSB3) Virus was assessed.

Results:

The highest L-AsnA immobilized activity and immobilization yield were achieved with
agar cakes bead. The purified S. maxima L-AsnA showed good antiviral activity against Coxsackie
B3 (CSB3) Virus in a dose-dependent manner with an IC50 value 17.03 μg/ml. The antiviral
mode of action is presumably due to their capability of inhibiting attachment, blocking the adsorption
and penetration event of the viral replication cycle with 89.24%, 72.78% and 72.78%, respectively.
Also, S. maxima L-AsnA showed anti-proliferation effect against lung carcinoma A549,
hepatocellular carcinoma Hep-G2 and prostate carcinoma PC3 human cancer cell lines, with an
IC50 of 22.54, 24.65 and 56.61 μg/ml, respectively.

Conclusion:

It is interesting to favor L-asparaginase of S. maxima which showed antiviral activity
and anti-proliferation effect against different types of human cell lines. Thus, S. maxima microalgae
might be a good source for L-AsnA enzymes and can be immobilized on natural polymers.
Import Need for Wound Care and Burn Dressings in India: A Bioeconomic Challenge
Authors: Yadav Vibhu , Mittal Amit , Bansal Parikshit , Singh Sachin K.
Published: November 2019

Objective:

To present an overview of import need for wound care and burn dressings in
India. This article provides a complete analysis of the import-export value of wound care and burn
dressings in India. It helps in preparing growth strategies, knowledge about leading players, recent
developments, business strategies, and manufacturing status of the wound care and burn dressings
in India.

Methodology:

A trend analysis of import-export was carried out for wound and burn dressings in India.
Raw data of the years (2008-2017) were collected from various market research analysis sites
and import need was identified.

Results and Discussion:

The detailed analysis reveals that India is a growing market for wound
and burn dressings and spends a lot of the exchequer on importing the subject commodity. Wound
dressing export is averaged to the same from 2013 to 2017. India saw a rise in wound dressing export
after 2012. India saw a rise of wound dressing import over the past 10 years. It averaged
502.6 million from 2008 to 2017 and it reached its all-time high of 765 million in 2016. The import
value was found quite high as compared to export.

Conclusion:

The report of import and export analysis very clearly highlights that there is a strong
demand for dressings in the country and due to lack of own manufacturers of such dressing in India,
these are imported. Since these products are expensive, there is a large outflow of Indian currency
due to imports. It is imperative that such products get government attention and should be
manufactured within the country.
MULTICULTURAL COMPETENCE OF PROSPECTIVE PRESCHOOL TEACHERS IN PREDOMINANTLY MUSLIM COUNTRY
Authors: Solehuddin Muhammad , Budiman Nandang
Published: November 2019

Prepared to teach young children in a multi-ethnic and religious society like in Indonesia, the prospective preschool teachers should have strong belief and practice in social justice and multiculturalism. However, this quality is not easily achievable by prospective teachers from ethnic and religious majority group, like Indonesian Muslim prospective preschool teachers who may have limited awareness and exposure to multicultural diversity. This study identified some existing multicultural competences of the participants before designing a training model to prepare prospective preschool teachers, to develop their multicultural competence. Data for this study were derived from the questionnaire and interview which reveal awareness, knowledge, and skill dimensions of multicultural competence. Findings show that the majority of the participants have a high level of multicultural awareness and indicate a difference in multicultural competence among different levels of students. Based on these findings and expert judgments, the study designs a training model to develop prospective preschool teachers’ multicultural competence which has the following sequence: systematic reflection, Socratic dialog, simulation, field practice, and reflection. The study also provides some recommendations on the inclusion of multicultural content into intracurricular and/or extracurricular activities as well as on testing and analyzing the effectiveness of the hypothetical training model resulted from this study.
Video Game–Based Rehabilitation Approach for Individuals Who Have Undergone Upper Limb Amputation: Case-Control Study (Preprint)
Authors: Hashim N A , Abd Razak N A , Gholizadeh H , Abu Osman N A
Published: November 2019

BACKGROUND

Brain plasticity is an important factor in prosthesis usage. This plasticity helps with brain adaptation to learn new movement and coordination patterns needed to control a prosthetic hand. It can be achieved through repetitive muscle training that is usually very exhausting and often results in considerable reduction in patient motivation. Previous studies have shown that a playful concept in rehabilitation can increase patient engagement and perseverance.

OBJECTIVE

This study investigated whether the inclusion of video games in the upper limb amputee rehabilitation protocol could have a beneficial impact for muscle preparation, coordination, and patient motivation among individuals who have undergone transradial upper limb amputation.

METHODS

Ten participants, including five amputee participants and five able-bodied participants, were enrolled in 10 1-hour sessions within a 4-week rehabilitation program. In order to investigate the effects of the rehabilitation protocol used in this study, virtual reality box and block tests and electromyography (EMG) assessments were performed. Maximum voluntary contraction was measured before, immediately after, and 2 days after interacting with four different EMG-controlled video games. Participant motivation was assessed with the Intrinsic Motivation Inventory (IMI) questionnaire and user evaluation survey.

RESULTS

Survey analysis showed that muscle strength and coordination increased at the end of training for all the participants. The results of Pearson correlation analysis indicated that there was a significant positive association between the training period and the box and block test score (r8=0.95, P<.001). The maximum voluntary contraction increment was high before training (6.8%) and in the follow-up session (7.1%), but was very small (2.1%) shortly after the training was conducted. The IMI assessment showed high scores for the subscales of interest, perceived competence, choice, and usefulness, but low scores for pressure and tension.

CONCLUSIONS

This study demonstrated that video games enhance motivation and adherence in an upper limb amputee rehabilitation program. The use of video games could be seen as a complementary approach for physical training in upper limb amputee rehabilitation.
La aplicación de los mecanismos de control del contrato de adhesión al contrato de trabajo
Authors: Villalba Sánchez Alicia
Published: November 2019

Las reformas llevadas a cabo por el Estado español durante la crisis
económica con la que dio comienzo el siglo en curso propiciaron el declive de
la negociación colectiva. El baldío dejado por ella fue progresivamente
cultivado por la individual, que también ha colonizado espacios donde la
carencia de regulación responde a la evolución tecnológica que impulsa la
Cuarta Revolución Industrial. El protagonismo adquirido por el contrato de
trabajo como fuente reguladora de la relación laboral ha ofrecido una mayor
flexibilidad al empleador par la gestión de sus recursos humanos. No obstante,
este logro ha sido alcanzado a costa de privar al trabajador de la protección
antaño derivada de la normativa estatal y de la negociación colectiva. A
resultas de esta involución se ha regresado a un contrato de trabajo donde el
riesgo de imposición de cláusulas ilícitas se ha materializado en litigios. Su
resolución obligó a los tribunales a acudir a conceptos jurídicos cuya vaguedad dificulta alcanzar un resultado predecible.

Asimmetrie informative e contratti bancari: L’esperienza italiana
Authors: De Poli Matteo
Published: November 2019

In Italia, la regolamentazione dei contratti bancari in Italia è divisa tra codice civile e legislazione speciale. Il primo, risalente al 1942,ha dato riconoscimento alle principali operazioni bancaria e le ha disciplinate, la seconda, invece, ha introdotto varie forme di tutela del cliente della banca, considerato soggetto “debole” e, quindi, a rischio di un esito contrattuale per lui svantaggioso. Lo scritto si propone di ricostruire, in modo rapido ma organico, la disciplina dei diversi contratti bancari e le principali forme di tutela del cliente di Banca.
La acción de amparo en Honduras: paradigma de la protección constitucional contra actos de particulares
Authors: C. Rosales Mauricio José
Published: November 2019

Los derechos fundamentales son un conjunto de prerrogativas iusnaturalistas inherentes a la persona que encuentra su razón axiológica en la dignidad humana, por tal motivo, al ser normas validas, estas limitan el poder coercitivo del Estado y, a su vez, dotan de contenido a todo el ordenamiento jurídico de un país. En consecuencia, ante los constantes cambios de la sociedad y la forma en que interactúan los individuos, se ha identificado que las trasgresiones sobre estos derechos actualmente no provienen únicamente de actos del Estado como detentador de la fuerza, sino, también, contra actos de particulares, razón por la cual amerita la intervención de la justicia Constitucional.

Violência institucional por omissão, negligência ou imperícia no manejo de medidas cautelares sob a égide da lei Maria da Penha
Authors: Da Silva e Silva Artenira
Published: November 2019

As medidas protetivas de urgência, previstas na Lei Maria da Penha, possuem o objetivo de tentar impedir as condições imediatas propícias à violência e as consequências da situação de vulnerabilidade da vítima em caráter de urgência. Apesar de representarem a maioria das ações em casos de violência doméstica, tal figura ainda possui natureza pouco explorada pela doutrina e jurisprudência pátrias. Toma-se por base um estudo de caso da primeira sentença declaratória de mérito da Vara Especial em Violência Doméstica e Familiar contra a Mulher de São Luís-MA, fazendo-se uso da análise de conteúdo da mesma. Pretende-se analisar a importância de se darem sentenças civis confirmatórias do dano às medidas protetivas de urgência, sob um viés do positivismo de combate, de modo a permitir uma proteção mais efetiva às mulheres em situação de violência doméstica.

Universidad: del capital humano a un modelo de empresa en la educación superior
Authors: Acevedo Tarazona Álvaro
Published: November 2019

Este artículo es una reflexión acerca del papel de la Universidad en la sociedad y sobre su cambiante configuración, hasta convertirse en una empresa. Al modelo universitario norteamericano, imperante durante los años sesenta y setenta, basado en la técnica y el conocimiento científico, lo está reemplazando un concepto neoliberal que ha hecho de la Educación Superior una unidad empresarial a partir de las lógicas del mercado. En este debate, la universidad se ha planteado desde dos orillas: en su función de empresa o de conocimiento, lo que lleva a preguntarse por los temas educativos de lo superior, sin resolución del continente, y por los enfoques locales y nacionales. ABSTRACTThis article is a reflection on the role of universities in society and their changing configuration into a business. The American university model, revailing in the sixties and seventies, based on the technical and scientific knowledge, is being replaced by a neoliberal concept that has made higher education a business unit from the logic of the market. In this debate, the university has been considered from two perspectives: on its role as a business or as an institution that promotes knowledge. The latter role has posed questions on higher educational issues and local and national approaches. RESUMOEste artigo é uma reflexão do papel da Universidade na sociedade e suas mudanças na configuración, até se tornar em uma empresa. O modelo da universidade norteamericana, prevalecente durante os anos sessenta e setenta, fundamentado na técnica e o conhecimento científico, o está substituindo um conceito neoliberal que fez da Educação Superior uma unidade empresarial partindo das lógicas do mercado.

Vertical and spatial price transmission in the Mexican and international milk market
Authors: Jaramillo-Villanueva José Luis , Palacios-Orozco Adriana
Published: November 2019

During the last two decades, the Mexican dairy sector experienced important structural changes, especially after the implementation of the NAFTA agreement. In 2016, the Bank of Mexico observed that in milk market, the final prices tend to rise when input prices increase, however; they do not decrease when input prices decrease. In this context, this study examines the degree of spatial and vertical price transmission between farm milk prices and international milk prices as well as between farm milk prices and retail milk prices, in order to assess the efficiency level of the Mexican and international dairy market. The findings of this research provide contributions to decision makers and industry stake-holders: a unidirectional transmission of international milk prices to domestic milk prices and from farm price to retail price along with the existence of asymmetric price transmission which depends on whether milk prices are increasing or decreasing. The results have shown that a long-run single co-integration relationship exists between international and farmer’s prices and between retail and farm price; that the direction of price transmission tends to go from producers to retailers and from international to farmer price and that when international price increase the speed of adjustment tend to be significantly slower, and that when international price decrease, the speed of adjustment tend to be significantly faster.

La rentabilidad de los establos lecheros está fuertemente asociada con el desempeño reproductivo. Por lo tanto, la identificación de factores de riesgo que comprometen este desempeño es primordial para implementar estrategias que mejoren la productividad. En este estudio, se probaron los efectos del uso de inseminación artificial (IA), hatos grandes y seroprevalencia alta de enfermedades infecciosas reproductivas sobre el desempeño reproductivo. Se incluyeron al estudio 52 establos (10-100 vacas; 959 lactaciones) registrando eventos reproductivos durante 18 meses (partos 2011-2012). Las seroprevalencias de neosporosis, rinotraqueitis infecciosa bovina (IBR) y diarrea viral bovina (BVD) se registraron en cada establo. Se utilizaron análisis de regresión logística múltiples para determinar el grado de asociación (razón de momios, OR) entre factores potenciales de riesgo y variables reproductivas. Establos ≥33 vacas y seroprevalencia alta de neosporosis fueron factores de riesgo para Asistencia al Parto (OR 1.5 y 2.3, respectivamente). Seroprevalencias altas de IBR y BVD fueron factores de riesgo para Días a Primer Servicio>70 Días en Leche (DPS>70, OR 1.3 y 1.9, respectivamente). La IA fue un factor de riesgo común para DPS>70 y Días Abiertos>110 Días en Leche (OR 2.4 y 1.3, respectivamente). Establos ≥33 vacas fue un factor de riesgo para Vacas No Gestantes al Primer Servicio (OR 1.7). En conclusión, la IA, establos ≥33 vacas y seroprevalencias altas de neosporosis, IBR y BVD son factores asociados al desempeño reproductivo en establos de producción de leche a pequeña escala en varias regiones geográficas de México.
Genetic variability in a Holstein population using SNP markers and their use for monitoring mating strategies

Published: November 2019

As genotyping costs continue to decrease, the demand for genotyping has increased among farmers. In most livestock herds, an important issue is controlling the increase in inbreeding coefficient. While this remains a large motive to genotype, producers are often unaware of the other benefits that genotyping could bring. The aim of this study was to demonstrate that SNP chips could be used as an effective herd management tool by utilizing a population of Italian Holstein-Friesian cattle. After filtering, the total number of animals and SNPs retained for analyses were 44 and 27,365, respectively. The principal component analyses (PCA) were able to identify a sire and origin-of-sire effect within the herd, while determining that sires do not influence individual genomic selection index values. The inbreeding coefficients calculated from genotypes (FIS) provided a glimpse into the herd’s heterozygosity and determined that the genetic variability is being well maintained. On the other hand, inbreeding coefficients on the genomic level were deduced from runs of homozygosity (FROH) and were compared to the inbreeding coefficients based on pedigree (FPED). Furthermore, 1,950 runs of homozygosity (ROH) were identified with the average length of ROH being 4.66 Mb. Genes and QTL within the genomic regions most commonly associated (top 1% and top 5% of SNP) with ROH were characterized. These results indicate that genotyping small herds, albeit at low-density, provides insights to the genetic variability within the herd and thus allows producers the ability to manage their stock from a genetic standpoint.

O artigo analisa o financiamento da educação no Brasil com o intuito de revelar a lógica que orientou a política de fundos (Fundef e Fundeb), suas dificuldades e limites para o financiamento do ensino médio em tempo integral de qualidade. O estudo bibliográfico sobre financiamento da educação e a análise das leis n° 9.394/96 (LDB), n° 9.424/96 (Fundef), n°11.494 (Fundeb) revelaram que a lógica do gasto, com a redistribuição de recursos pelo número de matrículas nos níveis de ensino e modalidades na educação básica, desde a implantação da política de fundos, não tem dado conta de ampliar o acesso ao ensino médio em tempo integral nos patamares estabelecidos pelo PNE (Lei n. 13.005/2014) e tampouco o acesso com qualidade. Como alternativa, destaca-se a lógica do custo (CAQI), que prevê os insumos necessários para um ensino médio em tempo integral de qualidade.
