INTRODUCCIÓN AL INTERNET DE LAS COSAS
Authors: Cueva Lovelle Juan Manuel , Rodriguez Molano Jose Ignacio , Montenegro Marin Carlos Enrique
Published: August 2017

Desde que kevin Ashton en 1999 acuñó el término de Internet de las Cosas (Internet of Things (IoT))  en una presentación para Procter & Gamble (P&G), la IoT se afianzó como un nuevo paradigma en el escenario de las comunicaciones inalámbricas [1]. El concepto de la IoT [2][3] se generaliza alrededor de una variedad de elementos, cosas u objetos de carácter cotidiano, como etiquetas de identificación por radiofrecuencia (RFID), sensores, actuadores, smartphones [4] y demás dispositivos móviles, los cuales son reconocibles, localizables y legibles por medio de esquemas de direccionamiento únicos capaces de interactuar unos con otros y controlables a través de internet [5] [6].

Impact of Different Modulation Data Formats on DWDM System Using SOA With Narrow-Channel Spacing
Authors: Rani Aruna , Singh Manpreet
Published: August 2017

In this paper, the transmission performance of 64×10 Gbps wavelength division multiplexing system using semiconductor optical amplifier (SOA) with 0.4nm channel spacing has been demonstrated with different modulation data formats. The suitability of various data formats like nonreturn to zero rectangular (NRZ-rectangular), nonreturn to zero raised cosine, return to zero raised cosine, return to zero rectangular, return to zero supergaussian and return to zero soliton for an optical transmission link at ‒40dBm signal input power is evaluated. The results have been carried out by evaluating the value of quality factor, bit error rate (BER), eye closure and received optical power. It is found that using NRZ-rectangular data format, the signal can travel up to a transmission length of 260 km with acceptable BER (1.10e-09) and Q-factor (15.0 dB), respectively.
Enhanced oral bioavailability of nisoldipine-piperine-loaded poly-lactic-co-glycolic acid nanoparticles
Authors: Rathee Permender , Kamboj Anjoo , Sidhu Shabir
Published: August 2017

Background:

Piperine helps in the improvement of bioavailability through pharmacokinetic interaction by modulating metabolism when administered with other drugs. Nisoldipine is a substrate for cytochrome P4503A4 enzymes. The study was undertaken to assess the influence of piperine on the pharmacokinetics and pharmacodynamics of nisoldipine nanoparticles in rats.

Methods:

Optimization studies of nanoparticles were performed using Taguchi L9 orthogonal array, and the nanoparticles were formulated by the precipitation method. The influence of piperine and nanoparticles was evaluated by means of in vivo kinetic and dynamic studies by oral administration in rats.

Results:

The entrapment efficiency, drug loading, ζ potential, and average particle size of optimized nisoldipine-piperine nanoparticles was 89.77±1.06%, 13.6±0.56%, −26.5 mV, and 132±7.21 nm, respectively. The in vitro release in 0.1 n HCl and 6.8 pH phosphate buffer was 96.9±0.48% and 98.3±0.26%, respectively. Pharmacokinetic studies showed a 4.9-fold increase in oral bioavailability and a >28.376±1.32% reduction in systemic blood pressure by using nanoparticles as compared to control (nisoldipine suspension) in Wistar rats.

Conclusion:

The results revealed that piperine being an inhibitor of cytochrome P4503A4 enzymes enhanced the bioavailability of nisoldipine by 4.9-fold in nanoparticles.
Persistent inhibition performance of amine polymers to inhibit clay swelling
Authors: Shu Xiaobo , Wan Liping , Duan Mubai
Published: August 2017

Clay hydration and swelling can cause shale instability in the drilling of oil and gas wells. The persistent inhibition performance of polyether amine (PEA) and poly(vinyl alcohol-g-dimethyl aminopropyl methacrylamide) (PVA-g-DMAPMA) as amine clay inhibitors has been investigated through hot rolling dispersion test, bulk hardness test, and bentonite inhibition test. The micro-mechanism has also been explained by Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), scanning electron microscope (SEM), and X-ray diffraction (XRD) analyses. Through the interaction of PEA and PVA-g-DMAPMA, the PEA can enter into clay platelets to exclude water molecules from entering and hydrating the clay, and the PVA-g-DMAPMA can affect the surface of clay minerals to prevent further intrusion of water molecules. Due to the effect of multiple cationic sites, both PEA and PVA-g-DMAPMA can maintain persistent clay inhibition and are less susceptible to reversing the adsorption.
High-Intensity Interval Exercises' Acute Impact on Heart Rate Variability: Comparison Between Whole-Body and Cycle Ergometer Protocols
Authors: Schaun Gustavo Z. , Del Vecchio Fabrício B.
Published: August 2017

Schaun, GZ and Del Vecchio, FB. High-intensity interval exercises' acute impact on heart rate variability: comparison between whole-body and cycle ergometer protocols. J Strength Cond Res 32(1): 223–229, 2018—Study aimed to compare the effects of 2 high-intensity interval training (HIIT) protocols on heart rate variability. Twelve young adult males (23.3 ± 3.9 years, 177.8 ± 7.4 cm, 76.9 ± 12.9 kg) volunteered to participate. In a randomized cross-over design, subjects performed 2 HIIT protocols, 1 on a cycle ergometer (Tabata protocol [TBT]; eight 20-second bouts at 170% P
max interspersed by 10-second rest) and another with whole-body calisthenic exercises (McRae protocol; eight 20-second all-out intervals interspersed by 10-second rest). Heart rate variability outcomes in the time, frequency, and nonlinear domains were assessed on 3 moments: (a) presession; (b) immediately postsession; and (c) 24 hours postsession. Results revealed that RRmean, Ln rMSSD, Ln high frequency (HF), and Ln low frequency (LF) were significantly reduced immediately postsession (p ≤ 0.001) and returned to baseline 24 h after both protocols. In addition, LF/HF ratio was reduced 24 h postsession (p ≤ 0.01) and SD2 was significantly lower immediately postsession only in TBT. Our main finding was that responses from heart rate autonomic control were similar in both protocols, despite different modes of exercise performed. Specifically, exercises resulted in a high parasympathetic inhibition immediately after session with subsequent recovery within 1 day. These results suggest that subjects were already recovered the day after and can help coaches to better program training sessions with such protocols.
Intracellular Proteolysis of Progranulin Generates Stable, Lysosomal Granulins that Are Haploinsufficient in Patients with Frontotemporal Dementia Caused byGRNMutations
Authors: Holler Christopher J. , Taylor Georgia , Deng Qiudong , Kukar Thomas
Published: August 2017

Homozygous or heterozygous mutations in theGRNgene, encoding progranulin (PGRN), cause neuronal ceroid lipofuscinosis (NCL) or frontotemporal dementia (FTD), respectively. NCL and FTD are characterized by lysosome dysfunction and neurodegeneration, indicating PGRN is important for lysosome homeostasis in the brain. PGRN is trafficked to the lysosome where its functional role is unknown. PGRN can be cleaved into seven 6-kDa proteins called granulins (GRNs); however, little is known about how GRNs are produced or if levels of GRNs are altered in FTD-GRNmutation carriers. Here, we report the identification and characterization of antibodies that reliably detect several human GRNs by immunoblot and immunocytochemistry. Using these tools, we find that endogenous GRNs are present within multiple cell lines and are constitutively produced. Further, extracellular PGRN is endocytosed and rapidly processed into stable GRNs within lysosomes. Processing of PGRN into GRNs is conserved between humans and mice and is modulated by sortilin expression and mediated by cysteine proteases (i.e. cathpesin L). Induced lysosome dysfunction caused by alkalizing agents or increased expression of transmembrane protein 106B (TMEM106B) inhibit processing of PGRN into GRNs. Finally, we find that multiple GRNs are haploinsufficient in primary fibroblasts and cortical brain tissue from FTD-GRNpatients. Taken together, our findings raise the interesting possibility that GRNs carry out critical lysosomal functions and that loss of GRNs should be explored as an initiating factor in lysosomal dysfunction and neurodegeneration caused byGRNmutations.
Esclavos/as y cimarrones, monarquía, poder local y negociación en Nueva España
Authors: Hernández Magdalena Díaz , García Octavio
Published: August 2017

Hasta ahora la historiografía había supuesto que nunca se sabrían los motivos del enfrentamiento entre los cimarrones que fundaron el pueblo libre de Santa María de Amapa, en México, en 1769. Nuevas fuentes de archivo nos han revelado lo sucedido, así como el protagonismo que tuvieron los esclavos procedentes de la gran rebelión y fuga de 1735 en Córdoba. Estos acontecimientos amplían nuestra visión sobre la capacidad negociadora de los esclavos cimarrones con las autoridades coloniales. La traición a sus compañeros del palenque, a quienes entregaron a las autoridades de Córdoba, les permitió obtener el perdón del virrey (1762) y formar dicho pueblo.

Historiography has thus far assumed that we would never understand the reasons for the confrontations of the maroon slaves that founded the free town of Santa María de Amapa, Mexico, in 1769. Previously unexamined archival sources reveal what happened and demonstrate the agency of the slaves dating back to their great rebellion and escape in Cordoba in 1735. These events provide us with new insights into the negotiating abilities of the maroon slaves with the colonial authorities. By betraying some of their own companions in their palenque to the authorities in Cordoba, they obtained the viceroy’s pardon in 1762 and established their town.

Published: August 2017

The objective of this research was to evaluate in vitro the inhibitory activity of essential oils from fresh leaves of Cymbopogon citratus (lemongrass) against Colletotrichum gloeosporioides in yam. The research was conducted in the department of Sucre, Colombia. The essential oils of C. citratus were collected in the municipalities of Sincelejo, La Union and Sampues, in September and October 2015. The essential oil was extract from fresh leaves using the microwave-assisted hydrodistillation. Concentrations of 5000, 8000 and 10 000 ppm of each essential oil were prepared. An absolute control, a positive control (benomyl 1 g/l) and a negative control was used. An inhibitory activity was obtained by using the direct seeding on surface of the potato-dextrose-agar method and it was expressed as percentage of inhibition rate. The chemical characterization of essential oils was performed by gas chromatography coupled to mass spectrometry. The highest percentages of antifungal index were observed in the lemongrass from Sincelejo at concentrations of 5000, 8000 and 10 000 ppm, after in La Union at 8000 and 10 000 ppm, and finally at Sampues at 10 000 ppm, with a value of 97.77%; the effect was similar to the positive control with benomyl 1 g/l. Citral was the main constituent of the essential oils extracted. The essential oils obtained from the three municipalities showed antifungal activity against C. gloeosporioides.

Published: August 2017

The aim of this study was to evaluate the conditions of co-crystallization of bitter orange juice with sucrose on the physicochemical properties of the product. Bitter orange juice was obtained with a mechanical juicer and concentrated on a rotary evaporator. Sucrose syrup 70 oBrix was subjected to heating and stirring of 1000 rpm, until a white color (118 °C) was observed. Bitter orange juice was added to the syrup, and the mixture was subjected to constant stirring of 600 rpm, to observe the formation of a particulate solid material. The co-crystals were dried, grinded and sieved. A dry co-crystal was determined: moisture, bulk density, solubility, water activity and repose angle. High proportion of bitter orange juice added (20%) and low content of soluble solids (50 °Brix) produced co-crystals with low moisture content (2.59%), water activity (0.52) and solubility time (69.4 s). High pH (4.5) of bitter orange juice concentrate produced co-crystals with low moisture contents (1.96%). The co-crystals of bitter orange juice showed good reconstitution characteristics (high solubility); however, these had high humidity (2.5 to 4.5%) and water activity (0.508 to 0.798).

Archaeological Footprints of the “Celtic Calendar”?
Authors: García Quintela Marco V. , Gonzalez-Garcia A. César
Published: August 2017

Despite their elusiveness, the people referred to as “Celts” by ancient chroniclers left behind certain archaeological remains that may be interepreted from the perspective of archaeoastronomy in an attempt to discover a calendrical “root” for them. In recent years, a number of studies on Late Iron Age sites, Roman or romanised locations and Christian landscapes in Hispania and in Gaul raised the possibility of detecting physical evidence of the celestial concepts that some classical authors attributed to the Celtic mystics, the Druids. However, these studies dealt with certain key aspects of how the Celts organised time that are not generally known and which tend to be presented in a summary way. Here, we explore aspects such as the difficulty of referring to a "Celtic calendar" per se, the sources for our study, the difficulties of adjusting the cycles of the Sun and Moon, the role of the “horizon calendars” and how these aspects may have played a role in actions that left a physical footprint that can still be seen today at several archaeological sites. We show that, although there may be common aspects that connect all Celtic sites and areas, there was no common calendar as such, although there are solid indications of the usage of a shared time-reckoning system.

Кризис и катастрофа экосистемы в советской кинофантастике
Authors: Сальникова Екатерина Викторовна
Published: August 2017

Данная статья посвящена развитию темы экологического кризиса и катастрофы в кинофантастике советского периода. Важность темы определяется не только актуальностью экологических проблем в современном мире, но и высокой популярностью фантастических жанров кинематографа, а следовательно, потенциально сильным резонансом фильмов означенной жанрово-тематической разновидности.

         В 1920-е годы в советском кино доминирует политическая фантастика. Причинами производства химического или иного опасного для окружающей среды оружия выступают либо стремление к политическому господству отдельных группировок, в том числе фашистских, либо жажда быстрого обогащения отдельных лиц. Фильмы вплотную подходят к отображению разрушения гармонии экосреды. Однако сама экосреда не является пока «действующим лицом» фильмов, последствия агрессивного воздействия на нее не визуализируются.

В 1960-е годы в российском  фантастическом кино  появляются визуальные образы экологического кризиса и катастрофы. Экосистема начинает восприниматься как живая участница масштабных и разнохарактерных конфликтов человечества. В политической фантастике и даже в сказке 1970–1980-х годов  возникает мотив страха перед гонкой вооружения, возможностью атомной войны, загрязнением окружающей среды, социальным неблагополучием. Мотив страха развивается в фильмах, действие которых происходит в капиталистической реальности. Однако это скорее способ высказаться о  проблемах человечества в целом, нежели в очередной раз заклеймить мировой империализм.

 Вплоть до середины 1980-х годов сохраняется вера в возможность преодоления проблем экосреды. В середине 1980-х годов кризис и катастрофа экосреды выступают как символ неблагополучия социума в целом и нравственности отдельных индивидов. Притчевая структура картин реализуется и в комедийной,  и в  трагедийной тональности. Кино развивает тему кризиса экосреды как духовного и физического испытания человека.    
Anticonvulsant effect of lercanidipine against pentylenetetrazole induced kindling in mice
Authors: Selvaraj Nitya , Kameswari Deepa , Gandhi Ramya , Raja Mohamad Meher Ali
Published: August 2017

Background: Emerging evidence has demonstrated the role of high-voltage -sensitive activated dihydropyridine (L-type, CaV1.x) channels in the development of epilepsy. Based on that we hypothesized that lercanidipine, a dihydropyridine calcium channel blocker, would protect against Pentylenetetrazole (PTZ) induced kindling in mice model of epilepsy.Methods: Kindling was induced in Swiss albino mice with PTZ in subconvulsive dose (30 mg/kg i.p.) thrice a week for nine weeks and the effect was scored using ‘4 point scoring system’. Rechallenging on the 3rd and 10th day with the same dose of PTZ was carried out after the last chronic dose.Results: The data of the present study demonstrated that pretreatment with lercanidipine (½ h before PTZ, in doses of 1 and 3 mg/kg i.p. daily) alone and in combination with diazepam (2mg/kg i.p.) had decreased the incidence and severity of seizure as well as prolonged the onset of kindling in a dose-dependent manner (p <0.05). On rechallenging, lercanidipine resulted in reduction of seizure score (p <0.05) and increased the seizure latency.Conclusions: The present study suggested that lercanidipine offered neuroprotection against PTZ induced kindling in mice.

Published: August 2017

Background: United Nations had passed MDGs followed by SDGs, half of which are based on women’s health. Despite best efforts, malnutrition remains a major problem that affects our country. This is a significant risk factor for maternal and foetal mortality. This study was conducted to identify current status of maternal wellbeing in villages under an RHTC to get baseline for further interventional studies in the villages.Methods: A descriptive study was done on the rural pregnant patients attending RHTC of LNMC and JKH situated at outskirts of Bhopal was done. All pregnant women attending RHTC from January 2016 to June 2017 were studied for nutrition indicators. Their weight and height were recorded and haemoglobin was measured by Sahli’s Haemoglobinometer and the data was compared. WMA Declaration of Helsinki was followed during this study.Results: Two hundred participants in this study were between age ranges 17 to 35 years with gravidity level of the participants ranging 1 to 5. Their Body Mass Index (BMI) ranging 14 to 30. One fourth participants were having BMI of 18.5 or less and four fifth had anaemia.Conclusions: Majority of pregnant women reporting for prenatal checkup at RHTC are malnourished and anaemic. It is recommended to study government scheme at micro level if it is serving as cash incentive for frequent and multiple pregnancy to potentially catapult the desired effect to worsen the situation of maternal health on one side and population control on the other. Health education for the rural public is recommended.

Published: August 2017

Os ambientes lagunares fluviomarinhos, conhecidos regionalmente por maceiós, são áreas utilizadas para prática de atividades pesqueiras e recreação, além do turismo. Sabe-se, porém, que a qualidade da água em muitos desses maceiós está comprometida, resultado do lançamento de efluentes e da falta de educação dos moradores que descartam resíduos nas margens, podendo causar doenças e acidentes a banhistas e animais marinhos. Este trabalho visa contribuir para o diagnóstico e caracterização desse ambiente, avaliando-se a qualidade da água dessas regiões por meio de análises físico-químicas de pH, temperatura, condutividade elétrica, turbidez, dureza total, dureza de cálcio e magnésio, oxigênio dissolvido, amônia, nitrito e fosfato, seguindo-se o Standard Methods of Water and Wastewater. O projeto foi desenvolvido no maceió localizado na antiga foz do Rio Jaguaribe, em Cabedelo-PB e em outro maceió, em João Pessoa/PB, na praia do Bessa, que também recebe água do Rio Jaguaribe. Definiram-se três pontos de coleta em cada área: o primeiro localizado no rio que desemboca no Maceió [amostras BR e IR(1,2,3)]; o segundo no próprio maceió [amostras BM e IM(1,2,3)]; e o terceiro na água do mar [amostras BS e IS(1,2,3)]. Realizaram-se cinco coletas, em triplicata autêntica, durante os meses de julho/2015 a abril/2016. Os resultados sugeriram que as amostras coletadas nos pontos do rio e maceió do Bessa apresentam uma maior concentração de poluentes que as do Intermares, devido ao fato de apresentarem concentrações mais elevadas dos nutrientes avaliados. A concentração do oxigênio dissolvido foi muito baixa em todas as amostras coletadas nos pontos do rio e maceiós do Bessa e Intermares, encontrando-se inferior aos 4 mg/L, preconizado pela resolução Nº 357/2005. A turbidez, condutividade elétrica e dureza total tiveram seus valores aumentados gradativamente no sentido rio, maceió e mar.

A reabilitação robótica vem recebendo destaque nos últimos anos por suas pesquisas relevantes na busca de dirimir problemas relacionados a pessoas que sofreram alguma amputação ou que necessitam melhorar suas capacidades motoras. Este trabalho apresenta o projeto de um dedo artificial, baseado parcialmente na fisiologia humana, na busca de contribuir para a solução de problemas citados por pesquisadores envolvidos com a reabilitação robótica, assim como por pacientes que necessitam de próteses convencionais. O protótipo desenvolvido foi fabricado em plástico ABS, usando uma impressora tridimensional de prototipagem rápida. O movimento de flexão do dedo foi realizado por molas de uma Liga com Memória de Forma (LMF) de Ni-Ti, ativados por aquecimento resistivo. Os testes realizados mostraram resultados relevantes aos encontrados na literatura internacional para dedos biométricos desenvolvidos com tecnologia semelhante, baseada em LMF.
Aspectos quantitativos da organização do trabalho no Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte
Authors: De Fiqueirêdo Gomes Maria Josely
Published: August 2017

Este trabalho tem como objetivo inferir o fator “Organização do Trabalho” (OT) a partir das variáveis sociodemográficas dos servidores do Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte (IFRN). A pesquisa se classifica como quantitativa e, quanto ao objetivo, trata-se de uma pesquisa descritiva. A amostra observada foi o instrumento de pesquisa “Inventário de Avaliação de Qualidade de Vida no Trabalho” (IA_QVT), sendo proporcional por campus (774). Na análise dos dados, foram usados os testes não paramédicos – U Mann-Whitney, Rho de Spearman e o de Quiquadrado – entre os itens menos pontuados do fator da Organização do Trabalho e as variáveis sociodemográficas. De acordo com a coleta de dados, apresentamos o seguinte resultado: 1. Com relação ao ritmo excessivo de trabalho, fica clara a forte relação dos servidores que têm cargo de direção com a percepção negativa no ambiente de trabalho, o que pode caracterizar um indicativo de possibilidades de adoecimento; 2. Outro fator relevante é a situação dos servidores não efetivos do IFRN, ou seja: terceirizados, estagiários e professores substitutos. Esse grupo indicou forte risco de adoecimento, já que o ritmo excessivo é um sinalizador de sobrecarga de trabalho; 3. Os servidores não efetivos sentemse, muitas vezes, por estarem em uma situação de subordinação, sem a liberdade de exercer suas tarefas de forma livre e criativa; 4. A pesquisa constatou ainda uma forte cobrança de prazo nos cumprimentos das tarefas para os servidores solteiros, separados e do gênero feminino; e 5. Outro aspecto a ser destacado trata das tarefas repetidas para quem tem menor renda: estagiários, terceirizados e mais jovens. Com relação ao fator OT, há uma necessidade de mudanças no ambiente laboral e de intervenções por meio de projetos de Qualidade de Vida no Trabalho (QVT), que venham a incrementar o bem-estar desses trabalhadores

Ocho comentarios al proyecto de Ley 038 de 2015
Authors: Arciniegas Cerquera María Fernanda , Onofre Arias Pablo Enrique
Published: August 2017

El Proyecto de Ley 038 de 2015, presentado por el Gobierno nacional, trae una serie de cambios importantes al régimen de libre competencia colombiano, algunos de los cuales han suscitado preocupaciones por parte de la academia.El presente documento analiza ocho puntos polémicos del citado proyecto, contribuyendo al debate que en torno a la propuesta del Ejecutivo se ha generado en la materia. Así las cosas, en primer lugar, se abordan los aspectos referentes a la estructura institucional de la Superintendencia de Industria y Comercio –sic– (independencia y concentración en un mismo órgano de las potestades de instrucción y juzgamiento en procedimientos administrativos). En segundo lugar, se examina la asignación de facultades jurisdiccionales a la Autoridad Nacional de Competencia para pronunciarse sobre pretensiones indemnizatorias en ejercicio de acciones individuales o de grupo. Enseguida, se estudia el papel del Consejo Asesor de este organismo, haciendo especial énfasis en las nuevas audiencias que propone el proyecto referido, para, a fortiori, analizar los inconvenientes que emergen del nuevo sistema de multas allí establecido. A continuación, se hace una breve mención en torno a la conveniencia o no de preservar el sistema de multas a personas naturales. Y se analiza el tema de la criminalización del régimen de competencia –haciendo referencia a la discusión que se ha producido a nivel internacional– y de la titularidad para ejercer la acción penal que se pretende otorgar a la Superintendencia de Industria y Comercio. Para finalizar, se examinan las modificaciones al régimen de integraciones empresariales que introduce el proyecto, particularmente lo atinente al carácter vinculante que se le quiere dar al concepto de la sic en materia financiera y aeronáutica.
Las disimilitudes de las altas cortes en la liquidación de intereses de mora en las obligaciones dinerarias en Colombia
Authors: Escobar Estrada Juan Gonzalo
Published: August 2017

El tema de los intereses de mora en Colombia ha sido muy debatido y cobra suma importancia. Tanto es así que las altas Cortes han tenido disímiles interpretaciones a la hora de liquidar las diferentes obligaciones.Ahora bien, los intereses en las obligaciones dinerarias deben ser considerados conforme las diferentes disciplinas del derecho, puesto que en nuestro país es diversa la forma de liquidar los intereses moratorios en materia comercial y civil, y aún más complejo en materia tributaria.Es por esto que se hace necesario hacer una compilación de los fundamentos de derecho que las altas Cortes han tenido para la liquidación de los intereses de mora en Colombia.El legislador ha establecido criterios diferenciadores a la hora de liquidar intereses de mora en las diferentes jurisdicciones del ordenamiento jurídico colombiano, siempre y cuando se recurra a criterios de razonabilidad y proporcionalidad que permitan garantizar el ejercicio eficaz y útil de aquellos. Lo anterior, en razón a que cada área del derecho pretende un fin, el cual no podrá sobreponer los principios de la Constitución Política.En el área mercantil no se admite el cobro de intereses moratorios y corrección monetaria simultáneamente, mientras que en materia civil sí es permitido, en razón a que los primeros tienen inmerso en la tasación de los intereses el efecto inflacionario y en el segundo, no está contemplado. Es de anotar que tanto el Consejo de Estado como la Corte Suprema de Justicia estuvieron en orillas diferentes, pero hoy comparten dicha posición.
Efficacy of Non-steroidal Anti-inflammatory Drugs for the Treatment of Acute Puerperal Metritis in Dairy Cows
Authors: Pohl Alina
Published: August 2017

Background: Acute puerperal metritis (APM) is a potentially life threatening, painful disease and is often treated with third-generation cephalosporins (Machado et al., 2014; Stojkov et al., 2015). An increasing antibiotic resistance is well documented and associated with decreasing clinical efficacy, animal welfare and economic consequences (Thomson et al., 2004). Hence, there is the need to evaluate alternative therapies to antibiotics.

Objective: The objective of this study was to assess the efficacy of ketoprofen for the treatment of APM compared with ceftiofur hydrochloride.

Materials and Methods: A total of 610 dairy cows from 6 farms in Germany were enrolled. Inclusion criteria was a rectal temperature (RT) ≥ 39.5 °C and a reddish-brown fetid vaginal discharge within the first 10 DIM. Cows meeting the inclusion criteria were randomly allocated to treatment with ketoprofen (3 mg/kg of body weight, n = 300) or treatment with ceftiofur (1 mg/kg of body weight, n = 310), both administered on 3 consecutive days. Rectal temperature was recorded daily for a period of 7 days after enrollment. Cows that showed RT ≥ 39.5 °C on day 4 to 7 after inclusion received an extended treatment (extT) with ceftiofur for 3 (ketoprofen group) or 2 (ceftiofur group) more days. Between 21 and 40 DIM cows were examined with the metricheck device and vaginal discharge was categorized on a 5-point scale according to the presence of pus.

Results: A total of 52 cows (35 from ketoprofen group, 17 from ceftiofur group) were excluded from analysis due to missing protocol compliance (n = 37) or concurrent disease (n = 15). Cows initially treated with ketoprofen had higher odds of extT than cows treated with ceftiofur (61% vs 31%, OR 3.47, P < 0.01, n = 558). Occurrence of purulent vaginal discharge (PVD) was similar for both treatment groups. However, cows with extT had 2.12 (P < 0.01, n = 438) times the odds of PVD than cows without extended treatment. Treatment group did not affect milk yield, first artificial insemination pregnancy risk, time to first AI and time to pregnancy.

Conclusions: The results indicate that although cows initially treated with ketoprofen were more likely to receive extT, fewer doses of ceftiofur (1.83) were required compared with cows initially treated with ceftiofur (3.63). Consequently, there is considerable potential of reducing antimicrobial treatment by implementing a treatment protocol starting with ketoprofen.

 
Multidimensional Psychological Stress During Pregnancies in Women Who Conceived via In Vitro Fertilization
Authors: Stevenson Eleanor L. , Silva Susan
Published: August 2017

Purpose: To explore relationships among the 3 psychological dimensions of stress, stimulus/environmental, perceptual, and emotional response, and then to develop a multidimensional composite measure of overall stress, and to determine demographic and clinical characteristics associated with stress in women who became pregnant via in vitro fertilization (IVF). Methods: Cross-sectional design using self-report questionnaires during the second trimester. Multidimensional stress was assessed with the Prenatal Life Events Scale, Life Event Distress Scale, Perceived Stress Scale, State-Trait Anxiety Index-State, and the Pregnancy-Related Anxiety Measure. Results: Participants (n = 144), aged 25–40 years, were enrolled June 2010–August 2011 from a private fertility clinic. Exploratory principal factor analysis was used to develop an overall stress score from the stress measures. Multiple stepwise regression analyses were conducted to determine characteristics related to the stress measures. White race tended to be associated with lower stress scores (p = .079). White participants also had lower perceived stress (p = .007), and those with a history of miscarriage had higher pregnancy-related anxiety (p = .035). Conclusions: White women had lower perceived stress. History of one or more miscarriage was associated with higher pregnancy-related anxiety. Additional research examining multidimensional stress is needed across the pregnancy trimesters as well as comparisons to women who conceived without IVF both in United States and internationally.
EMDR Therapy Program for Advanced Psychosocial Interventions Provided by Paraprofessionals
Authors: Jarero Ignacio , Rake Gregory , Givaudan Martha
Published: August 2017

The aim of this preliminary study was to evaluate the effectiveness of specially trained and supervised paraprofessionals in administering the eye movement desensitization and reprocessing Integrative Group Treatment Protocol (EMDR-IGTP) to reduce work-related posttraumatic stress disorder (PTSD) symptoms. The 2 paraprofessionals in this study were specially selected and trained in the application of the EMDR-IGTP and then provided treatment in an uncontrolled clinical trial to 37 clients from 3 non-governmental organizations in Bolivia. The participants were adult staff members (protective services workers, caregivers, psychologist, lawyers, and social workers) who provided care to children and adolescents with severe interpersonal trauma. Four EMDR-IGTP sessions within a parallel 2-week period were administered for each randomly assigned group. The Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5) was administered at pretreatment and 30 and 90 days’ posttreatment. A repeated measures analysis of variance (ANOVA) determined that PCL-5 score means differed statistically significantly between time points F(2, 72) = 574.53, p < .001, ηP2 = .94. The study presents preliminary evidence scaling up EMDR therapy in a low- and middle-income country, making it possible to reach larger numbers of people in a shorter time, thereby offering an operational advantage. The study has limitations specially related to the size of the sample, the use of only one measure, and the lack of comparison with a control group or treatment. Further studies are required to present large samples with more measures and comparison of results with another therapy or control group.
A estrutura do verbo em Apinayé
Authors: Albuquerque Francisco Edviges
Published: August 2017

Neste estudo, descrevemos e analisamos a estrutura do verbo na língua Apinayé, falada por aproximadamente 1.300 pessoas habitantes em sete aldeias situadas no extremo norte do Tocantins. Adotamos critérios morfológicos, sintáticos e semânticos, e daremos prioridade, em primeiro lugar, aos critérios morfossintáticos, visto que os verbos ocupam posições estruturais de dois tipos, dependendo do modo de indicar o objeto. Segundo Ham (1979: 01), os verbos em Apinayé possuem duas formas de raiz: a forma comprida, que ocorre somente quando o verbo é seguido de outras palavras na mesma frase; e a forma curta, na qual o verbo aparece em posição final na frase. Os verbos da primeira classe indicam, através do prefixo, que o objeto está implícito; já a forma curta tanto é usada com objeto explícito quanto com objeto implícito, quando as duas formas de prefixo ocorrem.
Concordância verbal de número em Kaingáng
Authors: D'Angelis Wilmar da Rocha
Published: August 2017

À primeira vista, é possível pensar que, na língua Kaingang, a concordância de número no verbo se faz por dois padrões: um para os verbos transitivos, outro para os intransitivos. Mas é justamente o fato de esses padrões fazerem coincidir o tratamento do verbo transitivo ao Objeto Direto (O) com o tratamento do verbo intransitivo ao Sujeito (S) da intransitiva que nos levam a concluir tratar-se de um único padrão, que superficialmente faz variar a concordância ora com Sujeito, ora com Objeto Direto. A concordância de número, no verbo, realiza-se morfologicamente por dois modos: alguns verbos podem ser reduplicados (reduplicação da última sílaba) enquanto outros possuem uma forma própria para o singular e outra para o plural. Essa comunicação pretende apontar algumas pistas para a investigação de todos os processos de construção do plural e de concordância de número em Kaingang.
Prefixos relacionais em Jê e Karajá
Authors: Ribeiro Eduardo Rivail
Published: August 2017

Este trabalho compara os chamados ‘prefixos relacionais’ em diferentes línguas do tronco Macro-Jê, dando ênfase especial às famílias Jê e Karajá. Prefixos relacionais, que marcam a contigüidade ou nãocontigüidade do núcleo de um sintagma com relação a seu determinante, ocorrem em pelo menos cinco das doze famílias do tronco Macro-Jê: Jê, Boróro, Ofayé, Karirí (Rodrigues 1994) e Karajá (Ribeiro 1996). Tal mecanismo ocorre também em línguas Tupí e Karíb (Rodrigues 1994), o que pode sugerir que sua presença em diversas famílias do tronco Macro-Jê seja antes um fenômeno areal do que evidência de origem genética comum. A comparação preliminar entre Karajá e Jê que apresentamos aqui, no entanto, sugere que prefixos relacionais podem ser reconstruídos para a língua ancestral comum às duas famílias, corroborando, assim, a hipótese acerca da unidade genética de pelo menos parte do tronco.
GÊNERO E ENFERMAGEM: UM ENSAIO SOBRE A INSERÇÃO DO HOMEM NO EXERCÍCIO DA ENFERMAGEM
Authors: Cunha Yasmine Fernanda Ferreira , Sousa Romário Rocha
Published: August 2017

Este ensaio objetiva discutir como se dá a inserção do homem na enfermagem, uma vez que, na área das ciências da saúde (exceto medicina), a atuação profissional de um homem em uma profissão vista como feminina e exercida em sua maioria por mulheres não se dá sem debates e discussões. O estudo da história nos possibilita conhecer o passado para compreender o presente. Tendo por base a história da Enfermagem, é possível compreender porque que a profissão carrega o estereótipo de gênero e como ocorre a inserção do homem na mesma. Por meio dessa releitura, percebe-se que a enfermagem se consolidou como profissão após o enfrentamento da hegemonia masculina na dominação do mercado de trabalho. Por outro lado, após consolidada, não permitiu a abertura da profissão para uma igualdade de gênero e atraiu pouquíssimos homens para atuar profissionalmente como enfermeiros. É necessário então, que os estereótipos de gênero sejam fragmentados nas profissões, para permitir o fim das desigualdades nas relações de trabalho.
On Natural Deduction for Herbrand Constructive Logics I: Curry-Howard Correspondence for Dummett's Logic LC
Authors: Aschieri Federico
Published: August 2017

Dummett's logic LC is intuitionistic logic extended with Dummett's axiom: for
every two statements the first implies the second or the second implies the
first. We present a natural deduction and a Curry-Howard correspondence for
first-order and second-order Dummett's logic. We add to the lambda calculus an
operator which represents, from the viewpoint of programming, a mechanism for
representing parallel computations and communication between them, and from the
viewpoint of logic, Dummett's axiom. We prove that our typed calculus is
normalizing and show that proof terms for existentially quantified formulas
reduce to a list of individual terms forming an Herbrand disjunction.
