Adaptive Abilities of Broad Bean (Vicia faba L.) Accession in Terms of Main Quantitative Traits
Authors: Georgieva Natalia , Kosev Valentin
Published: December 2019

The experimental activity was conducted at the Institute of Forage Crops (Pleven) during the period 2016 – 2018. The adaptive ability of 10 broad bean accessions was determined with respect to main quantitative traits based on parametric and nonparametric analysis. The environment influences to the highest degree the traits of 1st pod height, pods number and seed weight per plant. The plant height and seeds number were strongly influenced by the genotype, and the mass of 100 seeds was determined by the genotype × environment interaction. The broad bean accessions can be distributed as follows: Fb 1929 has a high value of the 1st pod height (34 cm) and is characterized by high plasticity and stability; BGE 029055 and Fb 1896 are stable and form a large number of pods per plant (11 – 15); Fb 1896 and Fb 2486 are distinguished with good adaptability and stability, increased seed weight (28.01 and 30.28 g, respectively) and 100 seeds mass (105.48 g and 91.31 g). Accessions BGE 032012 and Fb 2481 represent a selection value in terms of plant height (61.36 and 65.83 cm); Fb 1929 – in 1st pod height (32.46 cm); and BGE 029055, Fb 1896 and Fb 2486 – in pods number (10.59, 9.67 and 11.89). Fb 1896, Fb 2486 and BGE 041470 can be used to develop a new genetic diversity in breeding aimed at increasing the mass of 100 seeds and seed productivity.

Authors: Ptak Przemysław , Górecki Krzysztof , Dziurdzia Barbara
Published: December 2019

In this paper a problem of modelling thermal properties of large LED modules is considered. The compact thermal model of such modules is proposed. The form of this model is presented and a method of parameters estimation is described. The practical usefulness of this model is verified experimentally by comparing the results of calculations and measurements of internal temperature of selected LEDs included in LED modules. The modules were fabricated by Fideltronic, Poland and measurements of temperature distribution on the surface of the modules at selected variants of power dissipation were performed at the Gdynia Maritime University. Good agreement between the results of measurements and modelling was obtained.

Published: December 2019

Introduction: Camellia sinensis, a widely used plant, optimally grows in a low pH soil that in most cases contains high amounts of aluminum. Objectives: The aluminum content of the tea obtained from Camellia sinensis and other plants was compared. The influence of pH on the aluminum content of the tea was also measured. Materials and methods: The aluminum content of 48 samples was measured using a colorimetric method. The method is based on the ability of aluminum to form a stable complex with xylenol orange at low pH; this complex has an absorption maximum of 555 nm. Results: The method was validated for tea obtained with water and for tea obtained with water containing citric acid. The method proved linear over the rage of 0.7 – 7 ug/ml, coefficient of variation ranged between 2.6 – 7.68% (was dependent on the pH of the solution used to obtain the tea), accuracy was suitable for quantitative measurement (92.39-102.92%) and the complex proved to be stable for at least 1 hour. The following concentrations were measured: green tea (1.59 - 7.70 µg/ml), black tea (1.39 - 5.60 µg/ml), fruit tea (1.01 - 5.63 µg/ml) and herbal tea (1.03 - 5.24 µg/ml). Conclusion: The method proved useful and easily applicable for screening aluminum content of plants used for tea brewing. Camellia sinensis both green and black types had significantly higher aluminum contents than other type of teas. Adding citric acid, as would result from use of lemon juice, significantly increased the aluminum extraction from the plants used for tea brewing.
An event that impacted the Transylvanian pharmacist education 100 years ago
Authors: Mária Péter H.
Published: December 2019

In Kolozsvár, on 17th of September 1872, a Hungarian royal university was founded with 4 faculties 1- Law and Political Sciences, 2. Medical, 3. Arts (liberal), Language and History of Science, 4. Mathemathics and Natural History faculties. In 1881 the University picked up the Ferencz József University of Science name. There was no independent Medicine trainingfacultyt at this time yet. Pharmacists were taught in the Medical and Natural History faculties. In December 1918, during the first world war, Kolozsvár was moved under Romanian rule. On the 9th of May in 1919 the Romanian authorities called the acadamic senate (school staff) to do loyalty oath for the Romanian king.This was refused by the university teachers. After this event, teachers were moved out from this building along with the entire equipement of the University, and the place was occupied by the Romanian university. As, by this, theHungarian language acadamic education became impossible the first stage of the life of(Hungarian King) Ferencz József University of Sciense ended. First, the major part of theprofessors and students emigrated to Budapest while later on in 1921 the University wastemporarily established in Szeged. The University in Szeged took not onlythe legal continuity of the institute through its name but its professors also maintained and cherished all the traditions of the institute through many long coming years. Starting from 1921/1922 many student with transilvanian origin obtained pharmacist’s degree here many of whom later returned and worked in their native country.

Identification of Cause-and-Effect Relationships in the Real Estate Market Using the VAR Model and the Granger Test
Authors: Cellmer Radosław , Bełej Mirosław , Cichulska Aneta
Published: December 2019

The real estate market, as an open, complex and dynamic system, responds to changes in the environment of economic, legal or social conditions, although the pace and direction of these changes depends on the level of inertia of this system. At the same time, this market stimulates the market environment through prices. This study attempts to identify cause-and-effect relationships in the scope of the impact of selected economic and social indicators on prices of residential premises, as well as to identify the effects of price changes on these indicators. The time horizon of the study covered the years from 2008 to 2018. In the studies, to assess the stationarity of time series, an extended Dickey-Fuller test was used for the model with a free expression and linear trend, a vector autoregression model (VAR) was then constructed and Granger tests and impulse response analysis were performed using the Impulse Response Function (IRF). As a result, it was demonstrated that the response of real estate prices to the impulse from explanatory variables appears between the first and the fourth quarters, and expires after about three years.

Authors: Bayram Meliha , Derin Mehmet Emin , Doğan Halef Okan , Asan Gökmen , Şahin Mehtap , Şahin Ali
Published: December 2019

Introduction. Familial Mediterranean Fever (FMF) is an autoinflammatory disease. Prolidase is a specific imidodipeptidase that plays a role in collagen degradation, and an important role in inflammation and wound healing. Hypoxia-inducible factor-1α (HIF-1) is an important protein in the regulation of immunological response, hemostasis, vascularization. The aim of the study was to compare serum prolidase and HIF-1α levels in patients with FMF in attack-free period and healthy control group.

Methods. Between August 2017 and December 2017, sixty patients diagnosed with FMF according to the criteria of the Tel-hashomer and admitted to Sivas Cumhuriyet University Medical Faculty, Internal Medicine Rheumatology Department and sixty healthy volunteers were enrolled in the study.

Results. Median serum prolidase levels were 72.1 (25.1–114.9) ng/ml in FMF group and 30.7 (21.3–86.2) ng/mL in healthy control (HC) group (p = 0.018). ROC analysis showed that the sensitivity was 65% and the specificity was 68.3% at serum prolidase levels 54.03 ng/mL (p < 0.05). The median serum levels of HIF-1α in the FMF group was 482.0 (292.0–3967.0) pg/mL and 632.0 (362.0–927.0) pg/mL in the HC group (p > 0.05). There was no significant correlation between laboratory findings, sex, age, and prolidase (p > 0.05).

Conclusion. Serum prolidase enzyme levels in FMF patients with attack-free period were significantly higher than in the HC group. However, the role of prolidase and HIF1-α in the FMF disease needs to be clarified with more extensive and comprehensive studies.
Metaphor of Cosmos–as–Polis in the Stoic Teaching and its Ethical and Communicative Consequences
Authors: Shcherbakov F. B.
Published: December 2019

This article is considering origins of Stoic representation of Cosmos as The Universe State and there is briefly tracing its totemistic preconditions, which were proceeding from the primitive mythopoetic thinking’s specifics. Furthermore, there is proving a thesis about that the metaphor of Cosmos-Polis has emerged from searchings of an adequate philosophical language by early Greek thinkers, and that sociomorphical code was one of the most important metaphorical models of Cosmos in ancient philosophical poetics, not only for Stoics. A great number of political doctrines by Plato and faraway in the postplatonic tradition, including Stoa, were arising on the fundament of the this code. There is considering character of some Stoic ethical contradictions and is offering an attempt of resolving them through allocation of horizontically-civil and vertically-divine links in the Stoic teaching, which were containing peculiar dual system of communication of stoic sage with Cosmos.

O PRINCÍPIO DA DIGNIDADE DA PESSOA HUMANA COMO FUNDAMENTO PARA O ESTADO CONTEMPORÂNEO: UM OLHAR SOB O VIÉS DOS DIREITOS DA PERSONALIDADE
Authors: Souza Patrícia Verônica Nunes Carvalho Sobral de , Fachin Zulmar
Published: December 2019

O presente trabalho busca tratar o princípio da dignidade da pessoa humana como valor insculpido na ordem jurídica instaurada em 1988 pela atual Constituição Federal. A dignidade da pessoa humana, além de ser concebida como princípio constitucional, também ganhou substrato de princípio próprio em si mesmo, inerente à ideia de um Estado Democrático de Direito. Destarte, a dignidade da pessoa humana não atua somente como um princípio, mas como um valor superior que deve ser promovido para a aplicação de todas as normas do ordenamento jurídico pátrio. Para tanto, precisa-se compreender a origem desse valor-norma, bem como a distinção de sua aplicação nos planos individual e coletivo. A pesquisa utilizou o método de pesquisa bibliográfico, de caráter exploratório e descritivo, com fulcro em teses, artigos e doutrinas atinentes ao tema.
SUPREMO TRIBUNAL FEDERAL E DIÁLOGO INSTITUCIONAL: HÁ UM CONTROLE JURISDICIONAL DE POLÍTICAS PÚBLICAS NO BRASIL?
Authors: De Moraes Maria Valentina , Hennig Leal Mônia Clarissa
Published: December 2019

A relação entre os Poderes do Estado é colocada em jogo no que se refere à intervenção judicial em matéria de políticas públicas, vez que o Poder Judiciário - especialmente o Supremo Tribunal Federal -, acaba determinando, nesses casos, um facere aos demais Poderes. Pretende-se abordar, assim, como o mais alto Tribunal brasileiro vem se posicionando quanto à possibilidade de intervir nessa matéria e determinar que o Poder Executivo implemente políticas públicas previstas pelo Poder Legislativo ou, em caso de inexistência dessas, se há a determinação de sua criação. Para tanto, a partir de uma compilação de decisões proferidas no período compreendido entre janeiro de 2009 e janeiro de 2016, e posterior análise jurisprudencial, utilizando-se do método dedutivo, questiona-se: há, de fato, um controle jurisdicional de políticas públicas no Brasil? Nesse cenário, busca-se, ainda, analisar quais são os argumentos que cercam as posições adotadas pelo Poder Judiciário nesses casos e a relação que se estabelece entre o controle jurisdicional e o Princípio da Separação de Poderes, sob uma abordagem de diálogo institucional entre os três Poderes. Pode se afirmar, diante da análise realizada, a inexistência de um controle jurisdicional de políticas públicas propriamente dito, existindo, por outro lado, a determinação de concretização de um direito fundamental social ao particular. Também, é necessária uma maior abertura dos Poderes do Estado ao diálogo de forma a evitar constantes determinações judiciais que acarretam grandes custos ao Estado e se revestem de um caráter paliativo e não preventivo no contexto de judicialização existente.
L’ARMEE DES RESERVES DANS LA MONDIALISATION : LA PARABOLE DE LA FEMME ITALIENNE DE LA CONSTITUTION AU POST-FORDISME
Authors: Magliacane Alessia
Published: December 2019

Dans cette esquisse historico-politico-constitutionnelle j’essayerai un portrait de la société italienne au cours des étapes du passage d’une vision constitutionnelle que dirais-je « embryonnaire » jusqu’à une conscience qui est rapidement précipitée dans un gouffre que beaucoup de chercheurs définissent comme post-constitutionnel et post-démocratique.La première étape correspond aux premières années de vie de la Constitution républicaine, de la Résistance de 1944 à la constitution de la République et de l’unité politique de la nation datées de 1948, aux premiers pas de la reconstruction économique et sociale dans le contexte d’un monde bipolaire, jusqu’au tout début des années 1970.La deuxième naît des transformations dites « postfordistes » (moitié années 1970) et « postmodernistes » (moitié années 1980).Au cours de ces vagues imposantes de transformations sociales le rôle que « l’armée des réserves » des femmes a joué se révèle d’une importance majeure, tant pour la correcte compréhension des phases historiques que par rapport à la direction des évolutions sociales. Ce qui dans un pays comme l’Italie, caractérisée par un contexte constitutionnel parmi les plus avancés dans le monde occidental, et par une tradition juridique parmi les plus anciennes et mures au monde (dans laquelle droits humains, démocratie et droits sociaux fondamentaux se mêlent), nous permet d’aborder d’une manière approfondie et saisissante les enjeux globaux des phases à venir, marquées d’ores et déjà par une vision soit confusément « catastrophiste » soit naïvement « progressiste ».

Published: December 2019

AbstractThe study examined the impact of tax revenue on economic growth of Nigeria proxied as gross domestic product (GDP) from 2000-2017). The study employed Exploratory and ex-post facto designs and secondary data sourced from Federal Inland Revenue Services (FIRS), UNCTAD, FDI/MNE database, World Bank Report, United Nations Development Programme (UNDP) reports, CBN statistical bulletin were used. Ordinary Least Squares (OLS) regression technique was adopted to test the hypotheses of the study. The result reveals that tax revenue has significant impact on GDP in Nigeria with R-squared showing that about 87% variations in GDP can be attributed to tax revenue, while the remaining 23% variations in GDP are caused by other factors not included in this model. This is further emphasized by the T-statistic p-value of 0.001 which shows that the regression result is statistically significant because it is less than 5%, level of significance adopted for this study. The result from regression analysis also revealed that there is positive relationship between foreign direct investment and Gross Domestic Product, with a p- value of + 0.000, + 0.001 < 0.05% significance level. The study concluded that tax revenue has a significant impact on GDP in Nigeria. Also there is a positive relationship between FDI and economic growth in Nigeria; therefore the more FDI increases the more economic growth. The study recommended that functional tax structures that would ensure that tax is collected from all taxable individuals, group of individuals and corporate bodies and remitted accordingly to the government without diversion should be instituted to widen the revenue base of the country. Government should liberalize the Nigerian economy the more by removing all barriers to trade such as arbitrary tariffs, import and export duties and other levies to encourage foreign investors.

Published: December 2019

Documentar la presencia de especies de aves fuera de su lugar de distribución permite entender los patrones de distribución espacial y temporal de las aves, además de reflejar el valor ecológico con respecto a otros sitios. Los registros que presentamos aquí incluyen observaciones de 2009 a 2018 en la costa de Jalisco y Colima. Durante este periodo hicimos visitas mensuales o estacionales a los humedales costeros e islas cercanas a la costa con el fin de realizar un inventario y estimar las poblaciones de aves acuáticas. Como resultado de este estudio reportamos la presencia de ocho especies fuera de su área de distribución, entre las que se encuentra el ganso de Ross (Anser rossii), mérgulo de Craveri (Synthliboramphus craveri), alcuela oscura (Ptychoramphus aleuticus), paíño de Leach (Oceanodroma leucorhoa) y el petrel de Juan Fernández (Pterodroma externa). Además, realizamos el primer registro de anidación de la gaviota ploma (Larus heermanni), garza morena (Ardea herodias) y gavilán caracolero (Rostrhamus sociabilis). Cinco de las especies que observamos se encuentran en alguna categoría de protección en México, y otras cinco en la Unión Internacional para la Conservación de la Naturaleza. En el caso de algunas especies como la alcuela oscura, el petrel de Juan Fernández y el paíño de Leach, su presencia la asociamos con el paso de las tormentas tropicales Linda (2009), Juliette (2013) y Marty (2009), respectivamente, que afectaron la costa del Pacífico central mexicano. Al haber registrado la anidación de la gaviota ploma incrementamos 90 km más al sur su área de reproducción reportada, además es el primer reporte en Peña Blanca, Colima. La garza morena la registramos durante los tres años en que se visitó la isla Pajarera, en la bahía de Chamela, Jalisco: 2015, tres nidos; 2016, seis nidos, y 2017, cuatro nidos. En el caso del gavilán caracolero solamente observamos dos nidos en la laguna El Tule, Jalisco: uno en 2016 y otro en 2017. Con nuestros registros creció el listado de especies de aves acuáticas y documentamos nuevos sitios de anidación en la costa de Jalisco y Colima.

Resumen
Habiendo detectado la necesidad de actualizar las técnicas docentes empleadas por el
profesorado universitario, estamos desarrollando, en colaboración con el Departamento de
Ciencias Naturales del Colegio Cristo Rey de Jaén, el proyecto titulado “Transferencia de
prácticas docentes de trabajo cooperativo del ámbito pre-universitario a la docencia práctica
de asignaturas de Grado y Postgrado en la Universidad de Jaén”, concedido en la Convocatoria
de Proyectos de Innovación e Incentivación de las Buenas Prácticas Docentes en la Universidad
de Jaén y que implica a cuatro áreas de la Facultad de Ciencias Experimentales. En concreto
en el área de Microbiología hemos desarrollado un bloque de prácticas mediante la técnica de
Aprendizaje Basado en Problemas y el resto mediante la metodología tradicional de explicación
previa del profesor y desarrollo de la práctica. Tanto la motivación del profesorado como
de los estudiantes ha mejorado tras la aplicación de esta técnica docente. La adquisición de
competencias también ha sido superior en las prácticas desarrolladas con esta metodología, en
comparación con las desarrolladas por el método tradicional.
Concluimos que esta metodología docente se puede adaptar perfectamente a la
enseñanza universitaria, puede facilitar la comprensión del fundamento teórico y la adquisición
de competencias en algunas clases prácticas, además de mejorar la motivación tanto del
profesorado como de los estudiantes.
Abstract
Pre-university teachers have probed experience in applying new and innovative teaching
methods, so we have been guided by professors from the High School “Cristo Rey Jaén” to
develop these techniques in the scope of applicability of a Teaching Innovation Project titled
“Transfer of collaborative teaching techniques from pre-university levels to practical classes at
the University of Jaén”, that we obtained from this University and that implies the joint effort
of four areas of knowledge in the Faculty of Experimental Sciences at the University of Jaén.
Problem-Based Learning (PBL), a pedagogical approach and curriculum design methodology
often used in higher education, has been used in practical classes in the Microbiology Unit. We
have detected higher drive in both, teachers and students in those practical classes conducted
with this methodology, when compared to traditional techniques. Proficiency acquired by
students was also higher when applying this methodology, so we conclude it can be perfectly
transposed to University in order to improve the understanding of the theoretical basis of
practical classes, the competence acquisition by students and to increase the motivation of both,
teachers and students.

Published: December 2019

Resumen
La Colección de Invertebrados del Museo Nacional de Ciencias Naturales de Madrid reúne
más de 137.000 ejemplares de 27 fila del reino Animalia (incluidos los subfila Cephalochordata y
Tunicata, del filum Chordata, y exceptuados los fila Artrhopoda y Mollusca) y siete de organismos
unicelulares. De ellos 345 corresponden a holotipos. Los grupos mejor representados son:
Annelida, Bryozoa, Cnidaria, Echinodermata, Porifera, Platyhelminthes, Tardigrada y Phoronida.
Los ejemplares proceden principalmente de la península Ibérica, costas del Caribe, Pacífico
centroamericano y australiano y Océano Glacial Antártico. El origen de la colección se remonta
a 1771, fecha de creación del Real Gabinete de Historia Natural, del que procede el museo. Al
menos 300 ejemplares, en su mayoría esponjas y corales, son de esa época. Desde finales de la
década de los 30 del siglo XX y durante casi 50 años la colección contó con escasos medios. A
finales de los 80 hubo un impulso de recuperación que se intensificó en los 90 y, sobre todo, a
partir del 2000, cuando han ingresado en la colección casi el 70% de los ejemplares actualmente
existentes y siete de cada diez holotipos. En este tiempo se han desarrollado métodos de
conservación más efectivos, se ha estudiado una parte significativa del material histórico y se
ha establecido una estrecha colaboración con más de 30 centros de investigación, españoles y
extranjeros. Entre 2007 y 2017 han entrado en la colección más de 65.000 ejemplares y más de
1.467 tipos, 170 de ellos holotipos.
Abstract
The Invertebrates Collection of the Museo Nacional de Ciencias Naturales de Madrid
is composed of over 137.000 specimens representatives of 27 phyla of kingdom Animalia
(Prochordata included and Artrhopoda and Mollusca excluded) and also seven of singledcell organisms, 345 of which are holotypes. The main groups are: Annelida, Bryozoa, Cnidaria,
Echinodermata, Porifera, Platyhelminthes, Tardigrada and Phoronida. The specimens come mainly
from Iberian Peninsula, Caribbean coasts, Australia and Central America´s Pacific coasts of and
the Antarctic Ocean. The origin of this collection dates back to 1771, when the Royal Cabinet
of Natural History was created. At least 300 specimens, mostly sponges and corals, come from
this period. Since late 1930´s and for almost 50 years the collection has been careless. Since
late 1980s there was a significant recovery, intensified during the 90´s and above all in the
last 17 years, when a 70% of the present total specimens and seven out of ten of holotypes
entered in the collection. In this period new effective preservation methods were developed
and a significant part of the historical material was studied. Likewise, a closed collaboration was
established with at least 30 Spanish research institutions and 15 foreign centres. In the 2007-
2017 period over 65.000 specimens have been incorporated into the Invertebrates Collection,
more than 1.467 different types, with 170 holotypes.
Análisis del empleo de sistemas de respuestas
de audiencia (clickers) en clases magistrales de
microbiología en una Facultad de Medicina
Authors: Soria Glòria , Quandt Eva , Bru Samuel , Ribeiro Mariana , Ricco Natalia , Clotet Josep , Jiménez Javier
Published: December 2019

Resumen
Los clickers o Audience Response Systems (ARS) permiten a los alumnos responder
preguntas planteadas por el profesor a través de dispositivos móviles y sus respuestas aparecen
instantáneamente en la pantalla del aula, de manera que se pueden discutir y analizar en grupo
facilitando en gran medida un aprendizaje socrático y dirigido por iguales (peer instruction).
En la Facultad de Medicina de la UIC hemos empleado uno de los mencionados ARS,
Socrative, para analizar el conocimiento previo, comprobar la adquisición autónoma de
conocimiento, la adquisición de conocimientos después de una clase magistral y como repaso
antes de la evaluación.
Una encuesta anónima entre los estudiantes valora este tipo de sistemas en comparación
con una metodología basada en la lectura de clase magistral. Los resultados no muestran
diferencias estadísticamente significativas entre el método tradicional y el Socrative en cuanto
al grado de interés ni a los conocimientos adquiridos. Sin embargo, las calificaciones obtenidas
por los estudiantes con Socrative fueron significativamente superiores a las obtenidas mediante
metodología tradicional. Además el 89% de los estudiantes opina que Socrative es fácil de
usar, el 86% que mejora la participación en clase, el 85% que la ameniza, el 81% que facilita
la autoevaluación; sin embargo, solo un 54% opina que Socrative le ayudó a obtener mejores
resultados en la evaluación.
Abstract
The clickers or Audience Response Systems (ARS) allow students to answer questions
posed by the teacher through mobile devices and their answers appear instantly on the
classroom screen, so that they can be discussed and analysed as a group, greatly facilitating
Socratic and peer-directed learning.
In the Faculty of Medicine of the UIC, we have used one of the aforementioned ARS, —
Socrative— to analyse the following aspects: prior knowledge, the autonomous acquisition of
knowledge, the acquisition of knowledge after a master class and, finally, as a way to produce a
review before the evaluation.
We carried out an anonymous survey among our students to compare lectures where
Socrative was used with classical lectures based on the professor delivery of the content. The
results show no statistically significant differences between the traditional method and the
Socrative in terms of the degree of interest or the acquired knowledge. However, the grades
obtained by students with Socrative were significantly higher than those obtained when traditional
methodology was used. In addition, 89% of students think that Socrative is easy to use, 86%
that improves participation in class, 85% that enlivens it and 81% that facilitates self-evaluation;
however, only 54% think that Socrative helped them to improve their marks.
El cambio climático en el mar
Authors: Ros Joandomènec
Published: December 2019

A estas alturas del siglo XXI el impacto del cambio climático es evidente y muy preocupante. En lo que se refiere a los efectos en el mar, estos son difíciles de establecer porque el ambiente marino nos es todavía poco conocido, y las características físicas, los equilibrios químicos y las respuestas biológicas de los océanos se extienden desde la superficie al fondo y por un medio que tiene una inercia notable. Asimismo, apenas conocemos la dinámica de fenómenos a macroescala oceánica, o el funcionamiento de áreas no suficientemente estudiadas hasta ahora, como el océano Austral. Por si fuera poco, hay sinergias con otros impactos antrópicos, desde la contaminación y la invasión de especies alóctonas a la sobrepesca. Sin embargo, ya hay suficientes indicios y certezas de que el impacto del cambio climático se deja sentir en el mar y de que los efectos son aún más variados, globales y preocupantes de lo que se preveía. Además de los informes que elabora el Panel Intergubernamental sobre el Cambio Climático (IPCC) a escala global, en el Mediterráneo occidental ya son varios los estudios que tratan de esta cuestión, dentro de informes más amplios o centrados en el impacto sobre el paisaje marino y costero. Se pasará una breve revista a estos efectos, tanto al nivel oceánico global como en el Mediterráneo, y en particular en las costas catalanas, muchos de los cuales se han recogido en el Tercer Informe sobre el Canvi Climàtic a Catalunya (Martín-Vide, 2016)
Fish spawning strategies in the northwestern Mediterranean Sea
Authors: Sabatés Freijo Ana
Published: December 2019

The Mediterranean is globally considered an oligotrophic sea. However, there are some places or certain seasons in which mechanisms that enhance fertility may occur. These mechanisms, and related processes, are especially relevant in maintaining fish populations when they take place during the period of larval development. This contribution analyzes how environmental conditions occurring in the NW Mediterranean, at local and seasonal scales, determine the temporal and spatial patterns of fish reproductive activity in the region. The structure of the bathymetry, diversity of adult fish habitats and hydrodynamic mechanisms conditioning the primary production of the region (e.g., shelf-slope density front and associated current, continental water inflows, winter mixing, stratification of the water column) determine the location of spawning and the distribution patterns of fish eggs and larvae. A pronounced seasonal variability regarding both the number of species and the number of fish larvae in the plankton can be observed throughout the year. Most NW Mediterranean fish reproduce during the spring–summer stratification period, when the phytoplankton biomass values at the upper layers of the water column are lower than in winter. The development of the Deep Chlorophyll Maximum in this period and the high zooplankton biomass associated to it offers an important food source for the larvae. Additionally, during this period the inputs of continental waters are one of the fertilization mechanisms of surface waters and some species, as anchovy, takes advantage of this situation. Autumn–winter is the period with lower ichthyoplankton diversity, being dominated by sardine. Vertical mixing during winter is one of the mechanisms that enhance productivity. Overall, fish species show reproductive strategies and larval fish behavior that allow them to take advantage of the available resources throughout the seasonal cycle. These strategies, together with the high ecological efficiency of oligotrophic systems, contribute to the relatively high yield of Mediterranean fisheries. In a context of global change, understanding of the mechanisms relating environmental changes to the extent of spatial and temporal location of suitable spawning habitats of fish is a key first step to predicting and projecting such future changes, and thereby adapting to these changes.

Sugar is a strategic commodity for Indonesia, such that the availibility and the price have been managed by the government. The national production of Indonesia sugar has not been enough to cover the consumption, such that the deficit must be imported. Indonesian sugar was produced by 61 factories, where 51 units are State-owned Company. Unfortunately, the quality of sugar produced by State – owned factory has been getting worse, such that some are not qualified to the Indonesian National Standards (SNI). One of the reasons is poor process technology adopted, which is mostly using sulfitation technology. The Government, therefore, encourages industry to migrate the process technology from sulfitationsystem to defecation remelt carbonatation (DRK) system. This study assesses the techno-economy feasibility of the migration. The results indicate that technology migration is technically feasible, but for the business, Government needs to give price incentive to the product. Furthermore, the study recommends that adoption of DRK technology should be prioritized to the factories with abundant stock of baggase.

Maize hybridization system would help Indonesia to become a maize exporter. But the development of maize hybrids in Indonesia is seemed too slow, this impacting in national maize production, which was only 13 million ton per year in 2003. In 2009, the maize hybrid has been planted in about 54% of maize yields. Fertilizing maize is on the most essential and critical parts about growing maize. The objective of the study was to obtain the maximum dosage of composed fertilizer for the highest productivity among four hybrids maize variety in dependingsoil type. The result showed that the prospecting hybrid variety of BI-1 has a maximum production yield of 7.7 ton/ha at the level of fertilizer 1,200 kg/ha and it was only 6.3 ton per ha at zero level fertilizer. Amount of 7.4 ton/ha was achieved by BI-3 maize hybrid at the level of 1,200 kg/ha fertilizer, where those only 5.8 ton/ha at the zero level of fertilizer. The highest productivity was archived by BI-4 where it was 7.1 ton/ha at zero level fertilizer and the highest production yield of 9.2 ton/ha at 900kg/ha of fertilizer, but it was decrease at the level of 1,200 kg/ha fertilizer. Maize variety of DK979 achieved highest productivity of 8.6 ton/ha at 1,200 kg/ha fertilizer and 5.8 ton/ha at zero level fertilizer.
MITIGASI LAHAN TERDEGRADASI AKIBAT PENAMBANGAN MELALUI REVEGETASI
Authors: Sittadewi E. Hanggari
Published: December 2019

Salah satu dampak negatif dari aktifitas penambangan adalah terjadinya degradasi lahan. Degradasi lahan ditandai dengan menurunnya kondisi fisik, kimia dan biologi. Mitigasi atau upaya pencegahan harus dilakukan agar tidak berlanjut ke kondisi yang lebih parah. Revegetasi adalah langkah yang dapat dilakukan untuk mitigasi lahan terdegradasi tersebut. Keberhasilan revegetasi tergantung pada pemilihan vegetasi yang adaptif dan cepat tumbuh sesuai dengan karakteristik tanah, iklim dan kegiatan pasca  penambangan. Selain itu perbaikan kondisi fisik, kimia dan biologi lahan juga ikut menentukan keberhasilan revegetasi. Beberapa jenis tanaman cepat tumbuh (Fast Growing Plant) yang umum digunakan untuk revegetasi adalah sengon laut (Paraserianthes falcataria), akasia (Acasia mangium, Acasia crassicarpa), Lamtoro (Leucaena glauca), turi (Sesbania grandiflora), gamal (Gliricidia sepium). Selain tanaman cepat tumbuh, tanaman lokal juga menjadi pilihan untuk revegetasi. Keberhasilan revegetasi akan meningkatkan kadar bahan organik dan memperbaiki siklus hara serta meningkatkan jumlah dan aktifitas mikroba. Hal ini akan memperbaiki kondisi fisik, kimia dan biologi sehingga degradasi lahan pasca penambangan tidak terjadi lebih buruk.

In this paper the evaluation and repair of a bridge failure are presented. The method is of analytical bridge evaluation, which consists of in-situ visual inspection, measurement of the bridge dimensions and quality test of the steel material. The data were used as input in structure modeling using SAP 2000 in order to calculate the required strength (Ru) of each structural members. Calculation were done to obtain the design strength (ØRn) of structural members and connections.The bridge components are in a safe condition if its design strength is greater than or equal to the required strength or ØRn ≥ Ru, If not, the bridge is categorized as failed and then a repair method and strengthening shall be be performed. The result showed that all of structural members and connections are in a safe condition. Bridge failure is caused by such factors as less precise execution in the field, combination of a large bolt holes and tightening bolts that have not reached the minimum tensile strength.The proposed bridge repair method is to provide two pieces of plates. The plates were welded at the end of the rod and drilled at the position of the existing bolt holes in order to avoid the bolt shifting.Keywords : bridge failure, bridge evaluation, required strength, design strength, , repaired method  AbstrakPada makalah ini disajikan evaluasi dan perbaikan dari kasus kegagalan sebuah jembatan. Metode yang digunakan adalah evaluasi jembatan secara analitis yang terdiri dari pemeriksaan secara visual di lapangan, pengukuran dimensi jembatan dan pengujian mutu bahan baja. Data tersebut sebagai input dalam pemodelan struktur dengan SAP 2000 dan diperoleh kuat perlu (Ru) masing-masing batang. Perhitungan juga dilakukan terhadap kuat rencana (ØRn) baik batang maupun sambungan. Komponen jembatan dikatakan aman jika kuat rencana lebih besar atau sama dengan kuat perlu atau ØRn ≥ Ru. Kemudian dilakukan penentuan kegagalan jembatan serta metode perbaikannya. Hasil penelitian menunjukkan bahwa semua batang dan sambungan aman sehingga penyebab kegagalan jembatan bukan karena kekuatan batang maupun sambungannya melainkan faktor pelaksanaan di lapangan yang tidak tepat yaitu kombinasi antara adanya lubang baut yang besar dan pengencangan baut yang belum mencapai gaya tarik minimumnya. Metode perbaikan jembatan yang diusulkan adalah dengan memberi dua buah pelat penguat yang dilas pada ujung batang dan dilubangi sesuai dengan posisi lubang baut yang ada agar tidak terjadi pergeseran baut.Kata kunci : kegagalan jembatan, evaluasi jembatan, kuat perlu, kuat rencana, , metode perbaikan
