Lucien Hervé et l'Italie
Authors: Gebauer Imola
Published: May 2019

L’Italie a été une importante source d’inspiration pour Lucien Hervé, le photographe de Le Corbusier. C’est à Milan qu’il présente sa première exposition issue de cette collaboration et qu’il publie ses photos sur l’architecture d’après-guerre en France dans les revues Domus et Casabella. En dehors des commandes officielles, Hervé est retourné en Italie pour des vacances entre 1950 et 1990. Grâce à ses expositions plusieurs photographies prises à ces occasions sont devenues des ‘icônes’. D’autres moins connues révèlent un rôle très important accordé à l’homme, des études approfondies de l’architecture classique, et un regard moins rigoureux que la réputation de l’artiste ne le suggère. Italy used to be an important source of inspiration for Lucien Hervé, the photographer of Le Corbusier. It was in Milan that he presented his first exhibition sourcing from this collaboration. He published his photographs on post-war French architecture in reviews like Domus or Casabella. Between the 1950s and 1990s he returned to Italy for taking holidays, without official orders. Through his numerous exhibitions several photographs taken during these stays have become his “icons”. Others, the less known ones reveal a primordial importance given to men, to his deep studies of classical architecture and a less rigorous look than his reputation affirms it.

Published: May 2019

Background: This study was designed to investigate the difference in the prevalence of neuronal autoantibodies in patients diagnosed with established temporal lobe epilepsy (TLE) of unknown cause with mesial temporal sclerosis (MTS) and patients with TLE without MTS. Methods: In an observational cohort study design, we included thirty-three consecutive adult patients and divided them into two groups with and without MTS. We evaluated anti-neuronal and nuclear antibodies with immunofluorescence (IF) and enzyme-linked immunosorbent assay (ELISA), respectively. Results: From the thirty-three consecutive patients with epilepsy 17 (51.1%) had MTS of which 12 had unilateral and 5 had bilateral MTS. No significant difference was detected between seropositive and seronegative patients in MTS versus non-MTS groups. The studied autoantibodies were present in 16 patients, including gamma-aminobutyric acid receptor (GABA-R) antibodies being the most common in 11 (33.3%), followed by N-methyl-Daspartate receptor (NMDA-R) in 2 (6.1%), glutamic acid decarboxylase receptor (GAD-R) in 1 (3.0%), antiphospholipid (APL) antibody in 1 (3.0%), CV2 in 1 (3.0%), Tr in 1 (3.0%), recoverin in 1 (3.0%), and double-stranded deoxyribonucleic acid (dsDNA) antibody in 1 (3.0%) of our patients with focal epilepsy. In both MTS and non-MTS groups, eight patients were positive for antibodies; four patients were positive for GABA in the MTS group and seven for GABA in the non-MTS group. Conclusion: Neuronal antibodies were presented in half of patients with focal epilepsy, GABA antibody being the leading one. No specific magnetic resonance imaging (MRI) findings were found in the seropositive group. Our results suggest that screening for relevant antibodies may enable us to offer a possible treatment to this group of patients.

Potencia Reactiva: del despacho óptimo al cobro de tarifas - PARTE B
Authors: Gómez-Ramírez Gustavo Adolfo
Published: May 2019

Hoy día los sistemas eléctricos han evolucionado desde ofrecer un servicio básico de electricidad hasta brindar servicios con las más estrictas normas de calidad del suministro eléctrico pues hoy día estos tienen un mayor valor agregado para con los clientes. En el caso de Costa Rica, se rigen bajo la normativa establecida por la ARESEP, tanto para los parámetros de calidad del servicio y los precios, en el caso de la calidad se requiere regulación y control de las variables de la frecuencia-tensión. La presente investigación propone un modelo de tarifa diferenciado, el cual hace suponer una baja sustancial a las tarifas eléctricas hoy día establecidas y se utiliza como referencia lo desarrollado en parte-A de la investigación. Por esta razón, buscando la reducción de los costos de electricidad, se ha desarrollado una optimización lineal para realizar un despacho económico de la potencia reactiva, dándole valor a esta. Se propone un modelo tarifario que contempla lo anteriormente mencionado a fin de solucionar los problemas de costos de electricidad para con los clientes, en el cual, a través de los mecanismos correctos, estos serán los más beneficiados a partir de una tarifa diferenciada.
Otro uso importante de los hongos
Authors: Rosales-López Catalina
Published: May 2019

A los hongos se le atribuyen muchos beneficios sobre la salud humana, tal como a las plantas medicinales. No todos son venenosos o comestibles, existen otros usos importantes. En este artículo se resalta la propiedad que tienen los hongos para obtener pigmentos naturales. Los colorantes obtenidos de microorganismos cuentan con la ventaja de ser pigmentos con tonalidades específicas, sin efectos nocivos para la salud y con múltiples beneficios económicos a nivel industrial. Esta investigación tuvo como objetivo la obtención de pigmentos naturales (carotenoides específicamente) para su uso en animales a partir de dos hongos: Pycnoporus sanguineus y Rhodotorula spp. P. sanguineus se encuentra como cuerpos fructíferos de color rojo-anaranjado, ha sido estudiado principalmente para degradar lignina y celulosa de la madera y por la producción de cinabarina (antibiótico). En el caso de Rhodotorula spp es una levadura, sus colonias se caracterizan por ser de color anaranjado brillante, ha sido muy estudiada por la presencia de carotenoides. En el laboratorio, se aislaron y purificaron en medio sólido, se realizaron pruebas de medios líquidos que favorecieran su crecimiento y producción del colorante y se realizó el escalamiento para la mayor obtención de biomasa y por ende, del pigmento. Los hongos fueron liofilizados, se realizó una ruptura células con nitrógeno líquido y se tamizó, obtenido un polvo fino que se les suministró a los animales como parte de su dieta, con quienes se logró aumentar la coloración de la yema del huevo, de 12 a 14 de tonalidad, según el abanico de color amarillo.

Authors: Pradena-Miquel Mauricio , Cendoya-Hernández Patricio , Borkowsky-Opazo Andrés
Published: May 2019

Chile es uno de los mayores generadores de escorias de fundición de cobre (EFC) a nivel mundial con alrededor de 50 millones de toneladas acumuladas. Debido a que las EFC poseen características fisicoquímicas similares a las materias primas del cemento, resulta atractivo utilizar la EFC para la producción de morteros de pega sustentables para su uso en muros de albañilería.  De esta manera el objetivo del presente artículo es estudiar la factibilidad técnica de morteros de pega fabricados con un árido fino obtenido a partir de la combinación de arena y granalla de EFC para su utilización en muros de albañilería confinada. Esto se realiza comparando en laboratorio sus propiedades y características con respecto a un mortero patrón (sin EFC). Se analizan propiedades del mortero de pega, tales como la consistencia, densidad, resistencia a la compresión, resistencia a la flexión y resistencia a la adherencia; además de su influencia en la resistencia a la compresión y al corte de muros de albañilería confinada. Los resultados muestran que la incorporación de la EFC en morteros de pega para muros de albañilería tiene una influencia positiva, ya que se incrementan significativamente las resistencias de adherencia (20,2%), resistencia a la compresión (18,1%) y resistencia al corte (12%). De esta manera, se concluye que para las condiciones analizadas, utilizar de morteros de pega con EFC en muros de albañilería confinada es la técnicamente factible.
The Provision of Radd in Inheritance Between Islamic Jurisprudence and the Algerian Family Law
Authors: Aissa Maiza
Published: May 2019

This study is aimed to figure out  on how current legal device gives legal certainty over the excess of heritage partition (radd) in Algeria. The comparation between Islamic jurisprudence and the Algerian Family Law is used to analyse judicial consideration on which matters regarding the excess of heritage partition are based. The writer used normative law method which consists of statute approach and conceptual approach. The understanding of radd in Islamic scholars’ views differ from one another. Some scholars accept the concept and some do not. Those who disagree with radd consider that the excess of heritage should be given to bayt al mal as muslims representative. On the other hand, scholars who agree with the concept of radd have also different opinions regarding who are entitled to receive the excess of heritage. Some include spouse (husband or wife) but some exclude him/her. The Algerian Family Law gives provision in this case for a legal certanty, as it’s stated in the article number 167 of the Algerian Family Code that wife and husband are excluded to receive radd. They can only receive it in the absence of ashaba heirs/residuaries, other fixed share heirs, and  dzaw al arham (uterine relatives).Penelitian ini bertujuan untuk mengetahui bagaimana perangkat hukum saat ini memberikan kepastian hukum atas kelebihan bagian warisan (radd) di Aljazair. Penelitian ini menggunakan pendekatan perbandingan antara fikih Islam dan Hukum Keluarga Aljazair. Penulis menggunakan metode hukum normatif yang terdiri dari pendekatan perundang-undangan dan pendekatan konseptual. Pemahaman radd dalam pandangan sarjana Islam berbeda satu sama lain. Beberapa sarjana menerima konsep itu dan beberapa tidak. Mereka yang tidak setuju dengan radd menganggap bahwa kelebihan warisan harus diberikan kepada bayt al mal sebagai perwakilan muslim. Di sisi lain, para sarjana yang setuju dengan konsep radd juga memiliki pendapat berbeda tentang siapa yang berhak menerima kelebihan warisan. Hukum Keluarga Aljazair memberikan ketentuan dalam kasus ini untuk kepastian hukum, seperti yang dinyatakan dalam pasal 167 dari Kode Keluarga Aljazair bahwa istri dan suami dikecualikan untuk menerima radd. Mereka hanya dapat menerimanya tanpa adanya ahli waris/ashabah, pewaris bagian tetap lainnya, dan dzaw al arham (kerabat dekat).

Authors: Moss Colleen , Jackson Joanie
Published: May 2019

There is a critical shortage of neonatal nurse practitioners (NNPs) in the United States. The NNP shortage increases workload and negatively affects job satisfaction, which ultimately impacts patient safety. Therefore, it is imperative to identify strategies to improve job satisfaction and retention. Authors of current evidence supported the connection between mentoring and role transition, job satisfaction, and intent to stay. Mentorship is key to the success of new graduate nurse practitioners as they develop confidence in the nurse practitioner (NP) role. The aim of this integrative review is to examine the existing evidence regarding mentoring of advanced practice nurses and the potential impact on the NNP workforce.
Congenital Syphilis: A Challenging Case for NICU Clinicians
Authors: Carrier Jessica , Haughton Vivian
Published: May 2019

Congenital syphilis (CS) has been consistently on the rise in the United States since 2012, despite long-standing recommendations for routine testing and treatment of pregnant women. CS is associated with miscarriage, stillbirth, early infant death, and organ dysfunction in the newborn. Prevention is the optimal goal; however, early identification of infected infants is imperative to reduce the risk of serious, long-term complications. Clinicians must possess adequate knowledge of CS and the potentially life-threatening conditions that can arise to provide immediate and effective care. This case study portrays the clinical presentation of an infant with CS and the management of the multisystem effects of the disease.

Efficacité technique des exploitations avicoles productrices d’œufs au sud du Bénin
Authors: Siéwé Pougoué Emile Blaise , Manu Ibrahim , Labiyi Adédédji Innocent , Bokossa Thiburce
Published: May 2019

Dans un contexte d’importation massive de produits avicoles au Bénin, la problématique relative à la performance des exploitations avicoles nationales est au cœur du débat. Afin d’assurer une meilleure allocation des ressources productives, des considérations d’ordre socioéconomiques entrent en jeu. Cette étude visait à établir le niveau de performance des exploitations de poules pondeuses au sud du Bénin. A travers l’approche paramétrique, les niveaux d’efficacité technique ont été estimés à partir d’une frontière stochastique de production. Les données ont été collectées auprès de quarante-cinq exploitations avicoles au moyen d’enquêtes réalisées entre août et septembre 2016. Les analyses ont montré que ces exploitations étaient en majorité performantes malgré des écarts d’efficacité entre elles. Le capital humain, le travail, les traitements vétérinaires étaient les principaux facteurs significatifs du processus de production d’œufs. La régression de la fonction de production a révélé que la faible production résultait davantage de l’insuffisance technique des producteurs (84 %) que de la répartition inefficace des ressources (16 %). Les écarts d’efficacité s’expliquaient par des facteurs socioéconomiques, notamment l’appui de l’Etat, le niveau d’instruction, l’âge de l’aviculteur, ses compétences et la densité des élevages. En conclusion, au Bénin les exploitations avicoles enquêtées étaient performantes mais restaient fragilisées par des externalités.

Published: May 2019

L’application de l’échographie au contrôle de la reproduction chez l’espèce caprine suscite un intérêt grandissant. La présente synthèse vise à rapporter l’intérêt de l’échographie dans le suivi de la fonction de reproduction chez la chèvre. L’échographie permet d’établir un diagnostic précoce de gravidité chez la chèvre entre le 24e et le 29e jour après la saillie par voie transrectale et transvaginale, et entre le 34e et le 40e jour par voie transabdominale avec des sensibilités variant entre 65 % et 100 %. L’échographie permet également de déterminer le sexe et le nombre de fœtus, d’estimer le poids du fœtus et le stade de la gravidité, de diagnostiquer la mortalité embryonnaire/fœtale et la pseudo-gravidité. Elle est utilisée dans le diagnostic de l’anœstrus post-partum et le suivi de la dynamique folliculaire. Ces différentes applications ont permis de révolutionner la conduite de l’élevage des caprins. Cette synthèse apporte des éléments de repères utiles aux producteurs pour permettre d’organiser le rationnement des animaux gravides et de traiter les femelles chez lesquelles un anœstrus a été diagnostiqué pour les remettre à la reproduction.

La discriminación por maternidad y conciliación en el ámbito universitario = Discrimination for maternity and conciliation in university
Authors: Selma Penalva Alejandra
Published: May 2019

Resumen. Todavía quedan muchos obstáculos para alcanzar una plena igualdad entre mujeres y hombres. Por el momento, puede decirse que son muy escasos los ámbitos profesionales en los que se ha conseguido eliminar cualquier forma directa o indirecta de discriminación por razón de género. Paradójicamente, en el ámbito universitario, pese a los numerosos esfuerzos realizados al respecto, todavía existen ciertas formas de discriminación por razón de género que afectan tanto a docentes como estudiantes, y que, como las estadísticas se ocupan cada año de confirmar, se manifiestan con especial fuerza respecto a aquellas personas que asumen la atención cargas familiares. Estos factores de desigualdad se analizan de forma individualizada en este trabajo, al mismo tiempo que se plantean posibles soluciones que ayudarían a atenuar el problema.Palabras clave: igualdad, discriminación, maternidad, conciliación, universidad, estancias de investigación.Abstract. Many obstacles remain to achieve full equality between women and men. For the time being, it can be said that there are very few professional areas in which any direct or indirect form of discrimination based on gender has been eliminated. Paradoxically, in the academic context, despite the numerous efforts made in this regard, there are still certain forms of discrimination based on gender that affect both, teachers and students, and that, as the statistics are dealt with each year of confirmation, manifest themselves special strength with regard to those people who take care of family responsibilities. These factors of inequality are analyzed individually in this paper, at the same time that possible solutions are proposed that would help to mitigate the problem.Keywords: equality, discrimination, maternity, conciliation, university, research stays.

Published: May 2019

Resumen. La promulgación de la Ley 3/2007, de 22 de marzo, para la igualdad efectiva de mujeres y hombres, ha sido consecuencia de la acción pública de la sociedad democrática en favor de la igualdad de la mujer. Sin lugar a duda, este reconocimiento normativo de la igualdad constituye un paso importante, pero no suficiente. Un relevante instrumento para completar el anterior reconocimiento sería la negociación colectiva. La negociación colectiva representa una autentica oportunidad para dotar de real contenido la igualdad efectiva entre hombres y mujeres. El principal propósito de la negociación colectiva sería la fijación de pautas justas en la delimitación de la clasificación profesional por ser esta un engranaje de diferenciación profesional y salarial. Los convenios colectivos han de precisar los criterios en los que han de sustentarse los diferentes grupos y categorías profesionales en una empresa.Palabras clave: mujer, ley, discriminación, convenio colectivo, promoción profesional.Abstract. The promulgation of Law 3/2007, of March 22, for the effective equality of women and men, has been a consequence of the public action of the democratic society in favor of the equality of women. Undoubtedly, this normative recognition of equality is an im­portant step, but is not enough. An important instrument to complete the previous recogni­tion would be the collective bargaining. Collective bargaining represents a real opportunity to provide effective content for effective equality between men and women. The main purpose of collective bargaining would be to establish fair rules in the delimitation of the professional classification as this is a mechanism of professional and salary differentiation. Collective agre­ements must specify the criteria on which the different groups and professional categories in a company must be based.Keywords: woman, law, discrimination, collective agreement, professional promotion.

Authors: Medina Enríquez Andrea
Published: May 2019

ResumenEl turismo de naturaleza genera oportunidades para las comunidades rurales de países en vías de desarrollo; sin embargo, el crecimiento del sector turístico privado sin una regulación efectiva puede impactar negativamente en los destinos naturales. El objetivo de la investigación es comprender los principales impactos socioeconómicos del destino Baños en Ecuador y la actitud de los agentes privados frente a ellos. En una primera parte del estudio se recolectan las opiniones del 50% de los principales empresarios turísticos a través de una encuesta: alojamientos,  restaurantes y agencias de viajes. Los resultados son cotejados entre los diferentes grupos, revelando su nivel de conocimiento y conciencia respecto a la realidad de los impactos. En el estudio de distribución de las rentas, se comparan los ingresos de diversos actores que operan en uno de los principales atractivos naturales del destino turístico. Este último análisis demuestra la existencia de una fuerte inequidad en la repartición de los ingresos, y su origen en el monopolio de un recurso natural. Emergen nuevas líneas de trabajo, como la evolución de los impactos del turismo de naturaleza, modelos colaborativos de gestión y metodologías de investigación aplicables a contextos similares.AbstractNature-based tourism generates opportunities for rural communities in developing countries. However, the growth of the private tourism sector without effective regulation can negatively impact natural destinations. The main objective of this research is to understand main socioeconomic impacts of Baños destination in Ecuador and to know the attitude of the private stakeholders facing them. In the first part of the study, the opinions of 50% of private stakeholders (accommodation, restaurants andtravel agencies) have been collected. The results of the survey are compared among different collectives, revealing their level of comprehension and awareness regard to the reality of such impacts.In the next part of the research, the incomes of various entrepreneurs that operate in the same natural attraction of destination are collated. This last analysis shows a strong inequality in the incomes distribution and its origin in the monopoly of a natural resource.

ResumenEsta investigación parte de la necesidad de poner el foco en los espacios públicos identitarios, en los cuales la constante congregación espontánea y masiva de la ciudadanía, ha construido un patrimonio cultural inmaterial en ellos, a la hora de celebrar colectivamente en la ciudad. Desde este enfoque, se aborda el caso de la Plaza Baquedano en Santiago de Chile, mediante una metodología propia que contrarresta fuentes secundarias, principalmente periodísticas, con fuentes empíricas. Por lo que seaplican encuestas y entrevistas, con el fin de comprender el fenómeno desde el contexto urbano, social, celebración y patrimonio del lugar. Asimismo, lograr la perspectiva interna y externa del estudio de caso.Los resultados obtenidos confirman la existencia del patrimonio inmaterial y el carácter de identidad, que se ha generado con el paso del tiempo en este espacio público y, tanto la visión interna como la externa, consideran que debería ser catalogado como patrimonio cultural del país. Sin  embargo, esta mención no ha sido otorgada por alguno de los  instrumentos vinculantes en Chile. Por lo cual es una discusión abierta,ya que en la opinión de expertos consultados la complejidad de otorgar una figura de protección inmovilizaría el dinamismo que ha constituido a este lugar como tal.AbstractThis research departs from the need to focus in the public identitary spaces, in which the constant congregation spontaneous and massive of citizenship, has built an intangible cultural heritage in them, when it comes to celebrating collectively in the city.

So that, surveys and interviews are applied in order to understand thephenomenon from the urban, social, celebration and heritage context’s.In addition, to achieve internal and external perspective of the case. The results collated confirm the existence of heritage and the identity character, which has been generated over time in this public space and both vision internal and external, consider that it should be cataloged as country’s cultural heritage. However, this mention has not been granted by some of the binding instruments in Chile. Therefore it is an open discussion, since in the opinion of the experts consulted the complexity of granting a protection figure would immobilize the dynamism that has built this place as such.

Insights on CTC Biology and Clinical Impact Emerging from Advances in Capture Technology
Authors: Bailey Patrick , Martin Stuart S.
Published: May 2019

Circulating tumor cells (CTC) and circulating tumor microemboli (CTM) have been shown to correlate negatively with patient survival. Actual CTC counts before and after treatment can be used to aid in prognosis of patient outcomes. The presence of circulating tumor materials (CTMat) can advertise the presence of metastasis before clinical presentation, enabling early detection of relapse. Importantly, emerging evidence is indicating that cancer treatments can actually increase the incidence of CTCs and metastasis in pre-clinical models. Subsequently, the study of CTCs, their biology and function are of vital importance. Emerging technologies for the capture of CTC/CTMs and CTMat are elucidating vitally important biological and functional information that can lead to important alterations in how therapies are administered. This paves the way for the development of a “liquid biopsy” where treatment decisions can be informed by information gleaned from tumor cells and tumor cell debris in the blood.

Kentang merupakan tanaman pangan bernilai ekonomi tinggi yang rentan terhadap serangan busuk daun (Phytophthora infestans) pada musim penghujan. Penggunaan pestisida sintetik hasilnya belum memuaskan sehingga perlu dilakukan induksi ketahanan terhadap serangan penyakit. Tujuan penelitian untuk mengetahui pengaruh  pemberian asam salisilat dan K2HPO4 dalam meningkatkan ketahanan tanaman kentang pada musim penghujan terhadap penyakit busuk daun. Penelitian dilakukan di Kebun Percobaan Berastagi pada ketinggian tempat 1.340 m dpl. pada bulan September sampai dengan Desember 2015. Tata letak percobaan disusun berdasarkan rancangan acak kelompok dua faktor dengan tiga ulangan dan 18 kombinasi perlakuan. Faktor pertama adalah dosis asam salisilat  (a0 = 0, a1 = 0,1g/L, a2 = 0,2 g/L, a3 = 0,3 g/L, a4 = 0,4 g/L, dan a5 = 0,2 g/L propineb). Faktor kedua adalah dosis K­2HPO4 (k0  =  kontrol, k1 = 0,1 g/L, k2 = 0,2 g/L). Hasil penelitian menunjukkan bahwa kombinasi perlakuan 0,1 g/L asam salisilat dan  0,1 g/L K2HPO4 merupakan perlakuan terbaik menurunkan intensitas penyakit P. infestans dan kerusakan umbi kentang. Intensitas penyakit sampai 9 minggu setelah aplikasi hanya 7,46%, sedangkan kerusakan umbi hanya sebesar 0,35%. Jumlah umbi dan persentase kelas umbi per tanaman hanya dipengaruhi oleh K2HPO4, sedangkan bobot umbi tidak dipengaruhi kedua perlakuan.

Abstract

Potatoes are high economic value crops that are vulnerable to the attack of late blight (Phytophthora infestans) in the rainy season. The use of synthetic pesticides has not been satisfactory, so that should be induced for the disease resistance. The objective of the research was to determine the giving effect of salicylic acid and K2HPO4 in improving the resilience of the potato crop in the rainy season to late blight. The study was conducted at Berastagi Experimental Garden in altitude 1,340 meters above sea level, from September to December 2015. The layout of the trial is based on two factor randomized complete block design with three replications and 18 combination treatments. The first factor is the dose of salicylic acid (A0 = 0, A1 = 0,1g/L, A2 = 0,2 g/L, A3 = 0,3 g/L, A4 = 0,4 g/L and A5 = 0,2 g/L propineb), the second factor is the dose K 2HPO4 (K0 = control, K1 = 0.1 g/L, K2 = 0.2 g / L). The results showed that the combination treatment of 0.1 g/L of salicylic acid and 0,1 g/L K2HPO4 is the best treatment because it can reduce the intensity of the Phytophthora infestans disease and potato tuber damage. The disease intensity up to 9 weeks after application only 7.46%, while the tuber damage only 0.35%. The number and percentage of class tubers per plant only affected by K2HPO4, while the tuber weight was not influenced both treatments.

Kemoterapi merupakan aplikasi senyawa kimia (ribavirin) yang memiliki aktivitas antiviral guna menghambat ataupun menghentikan multiplikasi virus pada jaringan tanaman. Penelitian bertujuan mengetahui pengaruh konsentrasi ribavirin terhadap pertumbuhan shoot tip bawang merah untuk mengeliminasi virus OYDV. Penelitian dilaksanakan di Laboratorium Kultur Jaringan 3, Departemen AGH IPB dan Laboratorium Virologi Tumbuhan, Departemen Proteksi Tanaman IPB, sejak bulan Oktober 2015 hingga Juni 2016. Rancangan percobaan yang digunakan adalah kelompok lengkap teracak dengan dua faktor dan empat ulangan, setiap ulangan terdiri atas empat tabung kultur yang ditanam satu eksplan. Percobaan dilakukan secara terpisah pada dua kultivar bawang merah, yaitu Bima Brebes dan Tiron. Faktor pertama adalah konsentrasi ribavirin, yaitu 0, 5, 10, 15, dan 20 mg/L. Faktor kedua adalah ukuran eksplan (shoot tip), yaitu 1,1–2,0 mm dan 2,1–3,0 mm. Hasil penelitian menunjukkan bahwa peningkatan konsentrasi ribavirin menekan tinggi tunas cv. Bima Brebes, waktu muncul daun, tinggi tunas, dan jumlah daun cv. Tiron. Ukuran shoot tip yang lebih besar (2,1–3,0 mm) dapat meningkatkan persentase tumbuh eksplan dan mempercepat waktu muncul daun pada cv. Bima Brebes dan Tiron. Konsentrasi ribavirin yang diaplikasikan pada dua ukuran shoot tip masih belum dapat mengeliminasi virus OYDV pada kedua kultivar bawang merah.

Chemotherapy is an apllication of chemistry compound (ribavirin) that has antiviral activity to inhibit virus multiplication in plant tissues. The objective of the experiment was to evaluate the effect of ribavirin concentrations on shoot tip growth of shallot for OYDV eradication. The experiment was cunducted at Tissue Culture Laboratory 3, Agronomy Department and Plant Virology Laboratory, Plant Protection Department of IPB from October 2015 until June 2016. The experiment was arranged in a completely rendomized block design with two factors and four replications. Each experimental unit consisted of four bottles with one explant in it. The first factor was ribavirin concentrations, i.e. 0, 5, 10, 15, and 20 mg/L. Second factor was shoot tip sizes, i.e. 1.1–2.0 mm and 2.1–3.0 mm. The experiment showed that increasing ribavirin concentrations suppressed the shoot length of cv. Bima Brebes, and it also inhibited the time of leaf to emerge, shoot length, and leaf number of cv. Tiron. Increasing shoot tip size (2.1–3.0 mm) influenced percentage of explant growth and speed the time of leaf emergance of cv. Bima Brebes and Tiron. Ribavirin concentrations used in this treatment did not eradicate OYDV in both shoot tipe sizes of the two cultivars.

Background: Sevoflurane is one of the most frequently used inhaled anesthetics for general anesthesia. Previously it has been reported that at clinically used doses of sevoflurane, cerebral vasoreactivity is maintained. However, there are no data how sevoflurane influences systemic and cerebral circulation in parallel. The aim of our study was to assess systemic and cerebral hemodynamic changes as well as cerebral CO2-reactivity during sevoflurane anesthesia. Methods: 29 patients undergoing general anesthesia were enrolled. Anesthesia was maintained with 1 MAC sevoflurane in 40% oxygen. Ventilatory settings (respiratory rate and tidal volume) were adjusted to reach and maintain 40, 35 and 30 mmHg EtCO2 for 5 minutes respectively. At the end of each period, transcranial Doppler and hemodynamic parameters using applanation tonometry were recorded. Results: Systemic mean arterial pressure significantly decreased during anesthetic induction and remained unchanged during the entire study period. Central aortic and peripherial pulse pressure and augmentation idex as markers of arterial stiffness significantly increased during the anesthetic induction and remained stable at the time points when target CO2 levels were reached. Both cerebral autoregulation and cerebral CO2-reactivity was maintained at 1 MAC sevoflurane. Discussion: Cerebral autoregulation and CO2-reactivity is preserved at 1 MAC sevoflurane. Cerebrovascular effects of anesthetic compounds have to be assessed together with systemic circulatory effects. The study was registered at http://www.clinicaltrials.gov, identifier: NCT02054143, retrospectively registered.

Published: May 2019

Background

Pupillary abnormalities play an important role in identification of neurosyphilis. Among them, Argyll Roberston pupil is most typical and has been mentioned in many reports and studies. However, papers about Adie’s pupil associated with neurosyphilis are extremely rare. In the present study, we report a case of patient with bilateral Adie’s pupils as isolated manifestation of neurosyphilis.

Case presentation

we describe a 58-year-old retired Chinese woman with bilateral Adie’s pupils. Further evaluation revealed serologically positive for Treponema pallidum particle agglutination (TPPA), chemiluminescence immunoassays (CLIA) and rapid plasma regain (RPR) test (1:16). The Cerebrospinal fluid (CSF) examination revealed pleocytosis, elevated protein, and positive RPR (1:2), TPPA and CLIA. Final diagnosis of Adie’s pupils associated with neurosyphilis was made and other possible causes were excluded. Cephalosporin was used for treatment due to penicillin allergy. Despite effective anti-syphilis treatment, her pupils remained unchanged.

Conclusions

Adie’s pupil can be caused by neurosyphilis and is one of the most important pupillary changes in early neurosyphilis. Our study further underscore the necessity of syphilis screening in patients with Adie’s pupil due to further treatment consideration.

Backgrounds

The occurrence of segmental/lobar pattern pneumonia (S/L-PP) in children increases with years. The pathogens of the disease may change for the abuse of antibiotics and the application of vaccines. Therefore, pathogens of S/L-PP in hospitalized children and their association with clinical characteristics may have changed. Objective: To analyze the pathogens of S/L-PP in hospitalized children and their association with clinical characteristics. Methods: The current study analyzed the epidemiological and clinical characteristics of pathogens in children with S/L-PP at a single hospital between 1st Jan 2014 and 31st Dec 2018 retrospectively. The pathogens and their associations with clinical characteristics were statistically analyzed. Results: A total of 593 children with S/L-PP received treatment at a single hospital during the study period by inclusion criteria. 451 patients were single positive for one pathogen and 83 patients had multiple infections. Mycoplasma pneumoniae (M.pneumoniae) (72.34%) was the most commonly detected pathogen, followed by streptococcus pneumoniae (S.pneumoniae) (8.77%). The infection of M.pneumoniae in children with S/L-PP increased with years (p<0.05). The positive rate of M.pneumoniae increased with ages of patients (p<0.05). M.pneumoniae was statistically associated to the extrapulmonary manifestations while S.pneumoniae was statistically associated with abnormal white blood cells (WBCs) and C reactive proteins (CRPs) (p<0.05). Conclusion: M.pneumoniae was the most positive pathogen in children with S/L-PP. The positive rate of M.pneumoniae in children with S/L-PP increased with years and the ages of children. M.pneumoniae was associated with extrapulmonary manifestations while S.pneumoniae was associated with abnormal WBCs and CRPs.

Background: This study examined the feasibility of using a Multiple Mini Interview (MMI) station featuring a video-based case to assess empathic abilities of medical school applicants.
Methods: The study sample was composed of candidates who participated at admission interviews held in the MMI format at a medical school in South Korea. In this six-station MMI, one station included a 2-minute video clip of a doctor-patient communication situation to assess candidate emphatic abilities, and paper scenarios were used in the other five stations. Acceptability of the use of video-based case in the MMI by candidates was examined by investigating their perceptions of the MMI and the video-based case using a 41-item post-MMI questionnaire. Fairness of the test was assessed by means of differences in candidate perceptions and performance across different demographics or backgrounds. Construct validity was assessed by examining the relationship of candidate scores in the empathy station with those in other stations. The G-coefficient was analyzed to estimate reliability of the test.
Results: Eighty-two questionnaires were returned, a 98.8% response rate. Candidates showed overall positive perceptions of the video-based case, which did not differ across demographics or backgrounds. There were no differences in candidates’ perceptions of the patient-doctor relationship presented in the video. Candidate performance in the empathy station was not affected by individual demographics or backgrounds. Nor candidate performance in the empathy station was associated with that of any other stations. The G-coefficient was 0.83, which demonstrated high reliability.
Conclusions: The present study illustrates the feasibility of using the video-based case in MMIs to assess candidates’ empathetic abilities.
Early childhood pedagogy in a Ghanaian socio-cultural medley: A case study of two Kindergarten classrooms
Authors: Mumuni Thompson
Published: May 2019

In a quest for quality-driven early childhood education settings, it is important to explore subtleties that define socio-culturally-relevant pedagogy that is often ignored in scholarly literature. To address this gap in literature, a qualitative multi-case study approach was used to explore four Kindergarten teachers views regarding early childhood pedagogy over a six-month in Kindergarten classrooms in Tata School and at Kariba School. This study sought to establish "Why does children's socio-cultural contexts influence choice of pedagogy in kindergarten classrooms". The study was framed by Bronfenbrenner's framework, ecological theory. The sources of data comprised semi-structured individual interviews, pair-interviews and field notes of classrooms observations. Both within and across case interpretative analysis was used. The study established that, participants in the two cases perceived that a socio-cultural context-based pedagogy such as learning materials, storytelling, traditional songs and traditional rhymes supported children's development in terms of their understanding of concepts, language development, cognitive and moral development, respectively.

A radiação solar incidente (Qg) é uma variável importante em estudos agrícolas, particularmente para a estimativa da evapotranspiração e em modelos para produtividade, assim como para produção de energia. Entretanto, sua medição não é, em geral, realizada em estações meteorológicas convencionais. O objetivo deste trabalho foi avaliar dois modelos empíricos de estimativa de (Qg), a partir da temperatura, e adicionalmente traçar as isolinhas para o Estado de Mato Grosso do Sul. Dados de Qg diários foram obtidos por estações meteorológicas automáticas instaladas ao longo do estado e pertencentes ao Instituto Nacional de Meteorologia (INMET). Para os dois modelos foram gerados coeficientes locais de calibração. O desempenho de cada método foi avaliado através dos seguintes indicadores: o Viés, o erro quadrático médio (EQM), o erro absoluto médio (EA) e o índice de correlação (r). Os resultados mostraram que o Modelo 1 teve um melhor desempenho, apresentando um coeficiente de correlação de 0,77 e EQM e EA inferiores a 1,8 MJ. Isto significa que tal modelo é passível de utilização para estimativa de radiação solar, mas, dado à simplicidade, desempenho e significância.

O licenciamento ambiental no Brasil tem sido constantemente criticado devido a sua demora e efetividade. A maior parte das críticas é direcionada à falta de qualidade dos estudos ambientais necessários para a obtenção desse licenciamento. Porém, essas críticas são feitas de forma genérica e pouco estruturadas, limitando o seu aproveitamento para a melhoria do processo. O objetivo do trabalho é de analisar a qualidade dos Estudos de Impactos Ambientais (EIAs) de rodovias e ferrovias e gerar informações para aprimorar o licenciamento desses empreendimentos. Para tanto, aplicou-se questionário para população de Analistas Ambientais do Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis (IBAMA), adotando a metodologia da análise de conteúdo. Os resultados permitiram resumir as deficiências nos EIA em quatro dimensões: 1) falta de compreensão pelos elaboradores quanto aos objetivos e finalidade dos EIAs; 2) dificuldade de coordenação e integração dos diferentes estudos dos meios físico, biótico e antrópico para avaliação dos impactos ambientais; 3) ausência de competência técnica nas diferentes áreas do conhecimento ambiental; 4) falta de independência e isenção da equipe executora dos EIAs. Em geral, os problemas identificados nos EIAs de rodovias e ferrovias são semelhantes aos presentes em outros tipos de empreendimentos.
