Ob stoletnici rojstva prof. Milana Grošlja
Authors: Grošelj Nada
Published: May 2016

Pred sto leti se je 19. septembra rodil moj oče, akademik Milan Grošelj, dolgoletni profesor in predstojnik na Oddelku za klasično filologijo. Taka obletnica si nedvomno zasluži omembo v reviji, posvečeni slovenskim klasičnim študijam, ki jih je v svojem - žal razmeroma kratkem – življenju temeljno sooblikoval. Čeprav imam osebnih spominov nanj zelo malo, saj je umrl, ko sem imela tri leta in pol, me je vendarle spremljal na vsej življenjski poti: v spominih, ki mi jih je stalno pripovedovala moja mati in njegova bivša študentka, klasična filologinja Andreja Grošelj; v načinu, kako me je po zgledu njegovih seminarjev sama poučevala latinščino; v znanstvenem profilu mojih profesorjev na fakulteti, njegovih nekdanjih študentov; v izdajah latinskih beril, v znanstvenih prispevkih in nenazadnje v spominih mnogih ljudi, ki so ga poznali in je nanje naredil tak vtis, da so o njem radi pripovedovali še desetine let kasneje.
Svet bogov Vzhodnih Alp in Jadrana v stiku z rimsko civilizacijo III: Svet lokalnih božanstev iz Celeje in mestne okolice
Authors: Šašel Kos Marjeta
Published: May 2016

Municipium Claudium Celeiaje skupaj s štirimi drugimi noriškimi naselbinami, ki jih Plinij imenuje oppida ( Virunum, Teurnia, Aguntum in Iuvavum, N. h. 3.146), dobil pravice rimskega municipija pod Klavdijem. Celeja je bila eno najbolj cvetočih mest v Noriku in tudi eno od pomembnih provincialnih administrativnih središč; že pred tem je bila močna keltska naselbina, njeni prebivalci so bili keltski Tavriski. Tavriski so najkasneje v l. stol. pr. Kr. kovali svoj lasten denar (tako imenovane vzhodnonoriške oz. tavriskijske srebrne in tudi zlate novce) in si prizadevali doseči čim več neodvisnosti v okviru Noriškega kraljestva, v katerem so igrali najpomembnejšo vlogo Noriki, ki so kovali svoj denar na Koroškem (t.i. zahodnonoriški novci oz. novci Norikov), krožil pa je tudi na sosednjih območjih.
Poročilo z Mednarodne konference o klasičnih študijah (Atene - Delfi, 3.-5. aprila 2003)
Authors: Babič Matjaž
Published: May 2016

Glavni razlog za konferenco je bila pobuda, ki jo je v okviru grškega predsedovanja Evropski skupnosti dal grški minister za šolstvo in verske zadeve, Petros Efthymiou. Predlagal je ustanovitev mednarodnega centra za klasične študije, ki bi bil sestavljen iz dveh enot: ene v Italiji in ene v Grčiji. S tem je povzel zamisel, za katero se je v Svetu Evrope že leta 1995 kot prvi zavzemal Giorgios Papandreou, tedanji grški minister za šolstvo in verske zadeve.

Judje in Grki v Aleksandriji
Authors: Klun Klemen
Published: May 2016

Čeprav je bilo prav kulturno okolje velemestne Aleksandrije v Egiptu tisto, v katerem sta se grška in judovska kultura že od slovitega prevoda Mojzesove Postave naprej (III. stol. pr. n. št.) intenzivno prepletali, sega zgodovina poročil o stikih med Grki in starimi Izraelci daleč nazaj v čase kraljev Davida in Salomona. Razprava je kratek oris zgodovine teh stikov, posebna pozornost pa je posvečena judovskim reakcijam na helenistično nasilje Aleksandrovih naslednikov v Palestini, ter Ptolemajski Aleksandriji in grško pišočim judovskim avtorjem v mestu (Aristobul, Filon), ki so s svojim opusom pomembno zaznamovali tudi kasnejše krščansko branje in razumevanje (alegorija, tipologija) hebrejskega Svetega pisma.
Iam candidatus est fidei, quem filiorum et nepotum credens turba circumdat: zadnja stoletja rimskega poganstva
Authors: Maver Aleš
Published: May 2016

Prispevek obravnava usodo rimske poganske religije v zadnjih stoletjih njenega obstoja, predvsem v obdobju med 3. in 5. stoletjem po Kristusu. Najprej na kratko predstavi temeljne značilnosti rimskega poganstva, kot sta rimsko razumevanje pojma "numen" in osredinjenost na kultni formalizem. V nadaljevanju se ukvarja s silnicami, ki so prispevale k postopnemu upadu starih izročil, npr. splošno krizo rimskega cesarstva v drugi polovici 3. stoletja in prevladujoče henoteistične težnje v sočasnem verskem razvoju. Članek se posveča tudi poskusom poganske inteligence, da bi ohranila staro religijo, ki so dosegli vrh v neuspešni obnovi poganstva pod cesarjem Julijanom in doživeli dokončni poraz pod Teodozijem.
Društvo prijateljev humanistične gimnazije: branik klasično-humanistične izobrazbe v času med obema vojnama
Authors: Hriberšek Matej
Published: May 2016

Klasično-humanistična izobrazba, ki jo je dajala humanistična (klasična) gimnazija, je že v času Avstroogrske doživljala številne napade s strani reformističnih struj. Po koncu l. svetovne vojne in ustanovitvi nove države je nekaj časa vladalo zatišje; kmalu pa so se ti napadi nadaljevali. Zato so zagovorniki klasične gimnazije l. 1920 ustanovili Društvo prijateljev humanistične gimnazije, ki se je postavilo v bran nasprotnikom klasike, si prizadevalo za ohranitev obeh klasičnih jezikov v šolskem sistemu ter skrbelo za uveljavljanje antične misli in antičnega humanizma v javnosti.
Grška in rimska književnost pri gimnazijskem pouku latinščine in slovenščine

Na začetku moram priznati, da mi je precej neprijetno, ker sem se znašel v položaju, ko bi moral kot skoraj popoln zelenec na pedagoškem polju povedati nekaj modrih misli o blišču in bedi pouka antične književnosti pri slovenščini in latinščini. Spričo dejstva, da se nikakor ne morem sklicevati na koš izkušenj pri delu v tem vinogradu, se bom v svojem prispevku skušal omejiti na tisto, kar je vidno na prvi pogled, se pravi v prvi vrsti na gola dejstva o okvirjih, v katere so v naših gimnazijah ujeti grški in rimski pisci.
Dioniz ali Narcis? : mit o izgubi identitete pri Plotinu
Authors: Weiss Sonja
Published: May 2016

Plotinova alegoreza, ki povezuje orfiški mit o Dionizu  z mitom  o Narcisu,  temelji na skupnem motivu ogledovanja svoje lastne podobe v ogledalu oziroma v vodi. Temu  motivu,  ki predstavlja pomemben vidik Plotinove metaforike zrenja, dodaja avtor Enead element združitve  oziroma poskusa  združitve  z odsevom, ki ga pred tern ni mogoče  zaslediti v ohranjenih različicah  nobenega izmed  teh  mitov,  zato pa je prisoten v hermetični kozmogoniji. Kreativni vidik združitve  z odsevom  prevzame tudi Plotin v svoji teoriji o sestopu in utelešenju duše,  za katero uporabi prispodobo  Dionizovega ogledala. Nasprotno predstavlja Narcisovo koprnenje pogled vstran,  ki ima zanj usodne posledice. Duša, ki se ogleduje v »Dionizovem  ogledalu«,  ima se vedno  pred  očmi počelo, iz katerega izhaja, in zato ostaja zvesta svoji naravi, »Narcis« pa se izgubi,  ko utone v studencu navideznosti.
Domača tujost antičnih imen in Zakon o javni rabi slovenščine
Authors: Sunčič Maja
Published: May 2016

Članek odpira vprašanje o tujosti oziroma domačnosti antičnih imen za poimenovanje slovenskih podjetij glede na Zakon o javni rabi slovenščine (ZJRS) in obširno ter študijo Alenke Gložančev. ZJRS in jezikovnozavedna javnost problematiko antičnih imen v javni rabi večinoma zanemarjajo, razen v primerih višje stopnje tujejezičnosti. Postavlja se vprašanje, zakaj antična imena kljub identični ali morda še bolj pereči problematiki nejasnosti in ne-slovenskosti niso predstavljena kot problematična. Ali ZJRS res omejuje rabo antičnih imen ter z obrambo slovenske jezikovnokulturne dediščine še dodatno prispeva k izginjanju antike iz sodobnega vsakdanjika?
Demostenes: Tretji govor proti Filipu (prevod)
Authors: Babič Matjaž
Published: May 2016

S tem govorom, tretjo izmed štirih znamenitih 'filipik' (Φιλιπικ̀ι λόγοι, lat. Orationes Philippicae), je Demosten nastopil na zasedanju ljudske skupščine leta 341. Tistega leta je tudi večini prej mlačnih Atencem postajalo jasno, da Filipu II. ne bo dovolj oblast nad severno Grčijo, ki si jo je bil pridobil deloma z vojsko, deloma s spletkarjenjem in podkupovanjem, temveč da si namerava podjarmiti celotno celinsko in otoško deželo. V govoru Demostenes opozarja, da Filip posredno in neposredno krši mirovno pogodbo, sklenjeno med njim in Atenami leta 346 (t. i. 'Filokratov mir'), graja neodločne člane atenske skupščine, ki še vedno preveč popuščajo Filipovim pristašem, in zahteva od njih, naj se čimprej pripravijo na odločilni spopad z Makedonci ter naj zanj med Grki pridobijo čimveč zaveznikov.

Qui primus Romanorum Principum maiestatem dei singularis ac veri cognovisti: Paberki o Konstantinovi podobi pri krščanskih latinskih zgodovinarjih 4. in 5. stoletja
Authors: Maver Aleš
Published: May 2016

Članek obravnava nekatere pomembne odlomke pri latinsko pišočih krščanskih zgodovinarjih 4. in 5. stoletja, ki se nanašajo na prvega krščanskega rimskega cesarja Konstantina. Avtor ugotavlja, da so se že v tem obdobju izoblikovale pomembne razlike v pojmovanju cesarjeve osebe med vzhodnim in zahodnim krščanstvom. Le Rufin je zvesto sledil Evzebijevemu modelu in cesarja prikazal izključno pozitivno. Vsi ostali pisci so bili do njegovega lika bolj zadržani, kar še zlasti velja za Hieronima. Laktancij po drugi strani sicer ni postavljal pod vprašaj nobenega Konstantinovega dejanja, a je svoje bralce zmedel, ko je zelo povzdignil tudi lik njegovega socesarja Licinija.

Osnovna delitev je na napise mesta in agra, torej glede na najdišče; znotraj tega se napake delijo naprej na glasoslovne, oblikoslovne, pravopisne, skladenjske, besediloslovne ter tiste, ki se tičejo besedišča.
Assessment of Agricultural Sustainability at Regional Level in Slovenia
Authors: Slabe-Erker Renata , Klun Maja , Lampič Barbara
Published: May 2016

Due to the steadily evolving concept of sustainability and new challenges for European agriculture, the sustainability concept has not been fully operationalized in practice, particularly not in the local level. This paper aims to make the concept of sustainable development operational through the elaboration of the Regional Agriculture Sustainability Index (RASI). Our research hypothesis is that sustainability aspects are not equally represented in regional agricultural development. The research confirmed large regional differences in achieving sustainability in agriculture and, additionally, particularly large differences between the various aspects of sustainability. In general, Slovenian regions show high environmental sustainability, while there was an obvious gap in the economic and social area in seven or five regions, respectively. We assume that common agricultural policy (CAP) requirements with their emphasized environmental component significantly contribute to the picture of unbalanced agricultural sustainability in Slovenian regions.

Abstract. We present air–sea fluxes of carbon dioxide (CO2), methane (CH4), momentum, and sensible heat measured by the eddy covariance method from the recently established Penlee Point Atmospheric Observatory (PPAO) on the south-west coast of the United Kingdom. Measurements from the south-westerly direction (open water sector) were made at three different sampling heights (approximately 15, 18, and 27 m above mean sea level, a.m.s.l.), each from a different period during 2014–2015. At sampling heights  ≥  18 m a.m.s.l., measured fluxes of momentum and sensible heat demonstrate reasonable ( ≤  ±20 % in the mean) agreement with transfer rates over the open ocean. This confirms the suitability of PPAO for air–sea exchange measurements in shelf regions. Covariance air–sea CO2 fluxes demonstrate high temporal variability. Air-to-sea transport of CO2 declined from spring to summer in both years, coinciding with the breakdown of the spring phytoplankton bloom. We report, to the best of our knowledge, the first successful eddy covariance measurements of CH4 emissions from a marine environment. Higher sea-to-air CH4 fluxes were observed during rising tides (20 ± 3; 38 ± 3; 29 ± 6 µmole m−2 d−1 at 15, 18, 27 m a.m.s.l.) than during falling tides (14 ± 2; 22 ± 2; 21 ± 5 µmole m−2 d−1), consistent with an elevated CH4 source from an estuarine outflow driven by local tidal circulation. These fluxes are a few times higher than the predicted CH4 emissions over the open ocean and are significantly lower than estimates from other aquatic CH4 hotspots (e.g. polar regions, freshwater). Finally, we found the detection limit of the air–sea CH4 flux by eddy covariance to be 20 µmole m−2 d−1 over hourly timescales (4 µmole m−2 d−1 over 24 h).
Relationship between low-cloud presence and the amount of overlying aerosols
Authors: Chung Chul Eddy , Lewinschal Anna , Wilcox Eric
Published: May 2016

Abstract. Aerosols are often advected above cloud decks, and the amount of aerosols over cloud has been assumed to be similar to that at the same heights in nearby clear sky. In this assumption, cloud and aerosol above cloud-top height are considered randomly located with respect to each other. The Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) data are analyzed here to investigate this assumption on global scales. The CALIPSO data reveal that the aerosol optical depth (AOD) above low cloud tends to be smaller than in nearby clear sky during the daytime, and the opposite is true during the nighttime. In particular, over oceanic regions with wide-spread low cloud, such as the tropical southeastern Atlantic Ocean and northeastern Pacific Ocean, the daytime AOD above low cloud is often 40 % smaller than in surrounding clear skies.
Ragweed pollen production and dispersion modelling within a regional climate system, calibration and application over Europe
Authors: Liu Li , Solmon Fabien , Vautard Robert , Hamaoui-Laguel Lynda , Torma Csaba Zsolt , Giorgi Filippo
Published: May 2016

Abstract. Common ragweed (Ambrosia artemisiifolia L.) is a highly allergenic and invasive plant in Europe. Its pollen can be transported over large distances and has been recognized as a significant cause of hay fever and asthma (D'Amato et al., 2007; Burbach et al., 2009). To simulate production and dispersion of common ragweed pollen, we implement a pollen emission and transport module in the Regional Climate Model (RegCM) version 4 using the framework of the Community Land Model (CLM) version 4.5. In this online approach pollen emissions are calculated based on the modelling of plant distribution, pollen production, species-specific phenology, flowering probability, and flux response to meteorological conditions. A pollen tracer model is used to describe pollen advective transport, turbulent mixing, dry and wet deposition. The model is then applied and evaluated on a European domain for the period 2000–2010. To reduce the large uncertainties notably due to the lack of information on ragweed density distribution, a calibration based on airborne pollen observations is used. Accordingly a cross validation is conducted and shows reasonable error and sensitivity of the calibration. Resulting simulations show that the model captures the gross features of the pollen concentrations found in Europe, and reproduce reasonably both the spatial and temporal patterns of flowering season and associated pollen concentrations measured over Europe. The model can explain 68.6, 39.2, and 34.3 % of the observed variance in starting, central, and ending dates of the pollen season with associated root mean square error (RMSE) equal to 4.7, 3.9, and 7.0 days, respectively. The correlation between simulated and observed daily concentrations time series reaches 0.69. Statistical scores show that the model performs better over the central Europe source region where pollen loads are larger and the model is better constrained. From these simulations health risks associated to common ragweed pollen spread are evaluated through calculation of exposure time above health-relevant threshold levels. The total risk area with concentration above 5 grains m−3 takes up 29.5 % of domain. The longest exposure time occurs on Pannonian Plain, where the number of days per year with the daily concentration above 20 grains m−3 exceeds 30.

Abstract. The savanna complex is a highly diverse global biome that occurs within the seasonally dry tropical to sub-tropical equatorial latitudes. Savannas are open-canopy environments that encompass a broad demographic continuum, often characterised by a dynamically changing dominance between C3-tree and C4-grass vegetation, where frequent environmental disturbances such as fire modulates the balance between ephemeral and perennial life forms. Climate change is projected to result in significant changes to the savanna floristic structure, with increases to woody biomass expected through CO2 fertilisation in mesic savannas and increased tree mortality expected through increased rainfall interannual variability in xeric savannas. The complex interaction between vegetation and climate that occurs in savannas has traditionally challenged current-generation terrestrial biosphere models (TBMs), which aim to simulate the interaction between the atmosphere and the land-surface to predict responses of vegetation to changing in environmental forcing. In this review, we examine whether TBMs are able to adequately represent savanna dynamics and what implications potential deficiencies may have for climate change projection scenarios that rely on these models. We start by highlighting the defining characteristic traits and behaviours of savanna, how these differ across continents, and how this information is (or is not) represented in the structural framework of many TBMs. We highlight three dynamic processes that we believe directly affect the water-use and productivity of the savanna system, namely: phenology; root-water access; and fire dynamics. Following this, we discuss how these processes are represented in many current generation TBMs and whether they are suitable for simulating savanna dynamics. Finally, we give an overview of how eddy-covariance observations in combination with other data sources, can be used in model benchmarking and inter-comparison frameworks to diagnose the performance of TBMs in this environment and formulate roadmaps for future development. Our investigation reveals that many TBMs systematically misrepresent phenology, effects of fire and root-water access (if they are considered at all) and that these should be critical areas for future development. Furthermore, such processes must not be static (i.e. prescribed behaviour), but be capable of responding to the changing environmental conditions in order to emulate the dynamic behaviour of savannas. Without such developments, however, TBMs will have limited predictive capability in making the critical projections needed to understand how savannas will respond to future global change.

Published: May 2016

La Convención de los Derechos del Niño (CDN, 1989) es actualmente el tratado internacional más ratificado. Distintos autores han puesto de relieve su potencialidad para una educación moral y en la ciudadanía. Aun así, paradójicamente, distintas investigaciones informan de su incorporación escasa u ocasional en las prácticas escolares. En este artículo se realiza una aproximación a las experiencias escolares sobre participación, la tercera P de la CDN, desde la pluralidad de voces y actores de la comunidad educativa, mediante 14 grupos de discusión en 11 comunidades autónomas del estado español. El análisis de los discursos evidencia bajos niveles de participación del alumnado en la vida escolar. Pero, a la vez, se constata un escenario educativo propicio para el desarrollo de proyectos que contribuyan a la participación infantil, así como a la incorporación de la CDN como elemento motor de la vida del centro y referente integrador de los distintos proyectos de centro.

Authors: Ruiz Torres María del Carmen , Mérida Serrano Rosario
Published: May 2016

Este artículo presenta una etnografía desarrollada en un aula infantil a través de un estudio de caso. Se trata de una investigación cualitativa que focaliza su indagación en la capacidad de los Proyectos de Trabajo para contribuir al desarrollo profesional de la docente. Se analiza si el rol que la docente adopta al trabajar por Proyectos de Trabajo facilita su desarrollo profesional en tanto en  cuanto le ayuda a mejorar las estrategias de atención a la diversidad del alumnado y sus familias. Los resultados obtenidos arrojan los sentimientos de incertidumbre que experimenta la docente y sus dificultades para transitar desde la metodología tradicional hasta la implantación de Proyectos de Trabajo. Se muestra el tránsito desde un rol docente directivo hasta la asunción de un papel de acompañante en el aprendizaje del alumnado. Finalmente se identifican algunas resistencias en la cultura del centro que ralentizan la implantación de este método tanto en el aula, como su transferencia al resto de etapas del centro.

Published: May 2016

En un periodo de crisis socioeconómica como el que vive actualmente Europa, y en especial los países del sur, el poder adquisitivo de la población y el acceso a los alimentos pueden verse fuertemente alterados. Dicha crisis, sin embargo, no afecta únicamente a losaspectos materiales de la alimentación y al consumo, sino que, por el contrario, implica también una dimensión sociocultural más amplia que afecta a los estilos de vida de modo más integral. El objetivo de este artículo es observar en qué medida la crisis socioeconómicaque se inició en 2008 y que aún perdura, ha afectado a los hábitos de consumo y los estilos de vida de la comunidad autónoma de Cataluña (España). Para ello, se ha llevado a cabo en los últimos meses un trabajo de campo con entrevistas en diferentes estructuras familiares catalanas, de distintas características socioeconómicas, a través de lascuales los propios actores nos explican tanto su visión sobre cómo la crisis ha influido en su alimentación, como las estrategias que han puesto en marcha para hacer frente a esta transformación forzada de sus hábitos alimentarios cotidianos.

Quantifying the progression of a condition is one the most difficult challenges facing physicians as they look to provide the most effective treatment customized for individual patients. To achieve these goals, a novel image processing algorithm providing automated quantification has been developed to analyze the cranial vault and sutures using CT in humans and construct predictive models of the condition. Currently, very few preoperative or postoperative quantification tools exist for children with craniosynostosis so we used a customized active contour snake algorithm and 3D reconstruction to quantify the intracranial volume and measure the cranial sutures of these patients. A set of 117-patient CT scans was collected and analyzed, 77 with varying types of craniosynostosis and 40 normal patients as a control. Total intracranial volume was maintained in craniosynostosis patients in comparison to normal resulting in a uniform growth curve that showed no significant difference between the two groups. Assessing the asymmetry in the intracranial volume and measurements of suture volume and patency resulted in quantitative separations in synostosis types. These separations were further validated by a logistic regression model with pseudo R2 values greater than 0.95 and an 86.9% average accuracy in cross-validation of the seven groups, which increased to 91.9% with the removal of the underrepresented lambdoid synostosis group.

The objective of the present study was to evaluate the effect of four water salinity levels on the ingestive behavior of non-castrated crossbred Santa Inês sheep. Thirty-two non-castrated crossbred Santa Inês sheep in feedlot, at seven months of age and initial average weight of 21.76±1.25 kg, were used in the experiment. The experimental design was completely randomized, with four treatments and eight replicates. Four concentrations of salts in the water fed to the animals were evaluated: low (640 mg/l); medium (3,188 mg/l); high (5,740 mg/l) and very high (8,326 mg/l) levels of total dissolved solids (TDS). For the ingestive behaviors, the animals were observed every ten minutes, for 24 hours, to determine the time spent feeding, ruminating and idle. Also, cud chewing and the average number of defecations and urinations and the frequency of water ingestion were determined. The time spent feeding, ruminating and idle were not changed by the salinity levels in the water. Dry matter intake, neutral detergent fiber intake, total chewing time, total cud chews per day, number of daily meals, average duration of each meal and number of defecations per day did not change either. However, feeding and rumination efficiency in grams of DM/h, water intake and number of urinations were linearly affected, whereas the variables rumination efficiency in grams of NDF/h, grams of dry matter per cud, grams of neutral detergent fiber per cud, number of cuds, number of chews per cud and chewing time per cud presented quadratic effect. The different levels of total dissolved solids (640; 3,188; 5,740; and 8.326 mg/l) in the water fed to the sheep did not cause alterations in their ingestive behavior. In conclusion, water with up to 8,326 mg TDS/l can be an alternative strategic and seasonal method to water crossbred Santa Ines sheep.
Resumption of cyclic ovarian activity in postpartum ewes: a review

Published: May 2016

The reproduction rate is considered a crucial factor that affects the ability of producers to meet the growing demand for ovines meat, and optimizing this factor will maximize the production rate and increase the efficiency of livestock. A reduction in the length of the postpartum anestrus period results in a shorter interval between lambing and conception and enables more lambs to be produced throughout the life of a ewe. This review discusses the current knowledge of several factors associated with the resumption of cyclic ovarian function in postpartum ewes and how the suckling management of ewes may affect this process. Factors that influence the resumption of cyclic ovarian activity include uterine involution, follicular development, occurrence of silent ovulation and short estrous cycles, breed, reproductive seasonality, nutrition and lactation. Controlled suckling and early weaning are management practices that may be used to obtain three lambings in a 24-month period. In the majority of the studies the interval between lambing and first estrus was reduced when a controlled suckling management strategy was used, therefore the controlled suckling appears to be the best alternative because it has produced good results and is easy to implement. Currently, however, this practice is still not widely used.

One main obstacle to the development and expansion of pear tree cultivation in Brazil has been the lack of cultivars adapted to the edaphoclimatic conditions of regions with the potential for pear production. Intending to overcome this hindrance, Embrapa Clima Temperado (Embrapa Temperate Climate) developed and released the cultivar Cascatense, with a low cold requirement (~400 h) better suited for Rio Grande do Sul`s and Santa Catarina`s climate. Still, seedlings of high genetic and sanitary quality are necessary for the establishment of a high-yield orchard. Plants with both sanitary quality and uniformity can be obtained through in vitro micropropagation. Thus, the present study aimed to assess the influence of different culture media (MS, MS¾, WPM, QL, and Himédia), concentrations of sucrose (0, 15, 30, 45, and 60 g L-1), and concentrations of benzylaminopurine (BAP) (0, 0.4, 0.8, 1.2, and 1.6 mg L-1) upon the in vitro multiplication of cultivar Cascatense, to establish an efficient protocol to enhance its propagation and reproducibility. The study included three sequential experiments in which the number of shoots per explant, the length of shoots, the number of axillary buds per shoot, fresh mass, and dry mass of shoots were evaluated. Cultivar Cascatense can be best propagated in vitro with the use of Himédia medium, supplemented with 0.8 mg L-1 of BAP and 30 g L-1 of sucrose.

The use of saline water in agriculture has contributed to the expansion of irrigated areas, especially in arid and semiarid regions, where water deficits occur during various months of the year. In this context, this study aimed to evaluate the emergence, growth, and flowering of the castor bean cultivar “BRS Energia” as a function of the cationic composition of irrigation water, including water containing single and multiple types of cations. The experiment was carried out in a greenhouse in the municipality of Campina Grande-PB, Brazil using drainage lysimeters filled with a sandy loam Ultisol. The experiment was set in a randomized block design, with four replicates each of six water salinity treatments: Control; Na+; Ca2+; Na+ + Ca2+; K+; and Na+ + Ca2+ + Mg2, totaling 24 experimental plots, each consisting of five plants. Plants in the control treatment were subjected to irrigation using water having low electrical conductivity (ECw = 0.6 dS m-1), while the plants receiving other treatments were irrigated using 4.5 dS m-1 water containing different ions. Emergence and growth were more affected by the ECw than by the cationic composition of the irrigation water. The order of the cations in the irrigation water, in terms of negative effects, was Na+ > Na+ + Ca+ > Ca2+ > Na+ + Ca2+ + Mg2+ > K+. The cationic composition of the irrigation water influenced the time interval for inflorescence development and the opening of flower buds of the castor bean cultivar “BRS Energia”, and the most pronounced effects were observed in plants irrigated with calcic water.

Ectrodactyly is the term used to designate cases in which soft and bone tissue separation within the distal region of the thoracic limbs is present. It is observed in particular below the metacarpal bones and extending to the radius and ulna. In addition, it can often be associated with ipsilateral elbow luxation. We describe a case of ectrodactyly in a 3-month-old mongrel dog, where bone and soft tissue separation occurred between the third and fourth digits, extending proximally to the carpal region. We identified shortening of the ulna without elbow luxation. The dog was subjected to a surgical procedure comprising bone and soft tissue reconstruction and ulnar diaphyseal osteotomy, which was fixed using a Steinmann pin in the intramedullary canal, maintaining a distance of 1 cm between the two ulnar fragments. Two distal phalanges were removed because it was not possible to reposition them anatomically in the limb. The dog walked with mild lameness nine months after surgery.

The objective of this study was to evaluate the effect of sex class (castrated; non-castrated) and level of food restriction (0%, 30% and 60% of ad libitum consumption) on the quantitative composition of carcass and non-carcass components of Santa Ines lambs. A completely randomized 3x2 design (restriction level x sex class) was used to evaluate thirty lambs approximately two months of age with an average initial body weight of 13 ± 1.49 kg. When the average body weight of the animals in one of the treatment groups reached 28 kg, all animals were slaughtered. Sex class had effect on body weight at slaughter, empty body weight, hot carcass weight and cold carcass weight. The weight of the leg was greater in non-castrated animals. There was linear decreased effect according to increasing levels of restriction for the carcass cuts, except for leg and rear loin yield. There was statistic difference between sex class for the weights of kidneys, paw, and large intestine of non-castrated animals (P < 0.05). There was a negative linear association between level of food restriction and mass of blood, head, leather, paw, rumen, reticulum, abomasum, small intestine, large intestine; perirenal, omental, mesenteric and heart fat. The quantitative composition of carcass and non-carcass components of Santa Ines lambs is influenced by sex class and food restriction level.

The aim of this study was to evaluate the effect of cross breeding, finishing system, and gender on the relative growth of carcass tissues of dairy kids. Seventy eight kids (39 male and 39 female) from five breed types were used: Alpine; ½ Boer + ½ Alpine (½ BA); ½ Nubian + ½ Alpine (½ ANA); ¾ Boer + ¼ Alpine (¾ BA); and ½ Nubian + ¼ Boer + ¼ Alpine (TC). Kids were distributed into two finishing systems: in pasture with doe (FS1) and weaned in feedlot (FS2). Kids were slaughtered at a mean age of 128.4 ± 7.9 days and mean live weight of 22.07 kg. The mean weight of half carcasses was 5.09 kg. To determine allometric growth, we used the exponential equation Y= aXb. In the half carcass, muscle tissue showed comparatively early growth in group ½ BA, whereas fat tissue of animals in FS1 had relatively late growth. Females exhibited early growth of muscle tissue, while in males this tissue was intermediate. The ½ BA first-cross improved carcass characteristics by enhancing the growth of muscle tissue.

Authors: Guiyu Dai , Yang Liu
Published: May 2016

This paper first reviews the developmental history and status quo of Business English Program in China. Then based on the theory of needs analysis, it researches on 226 questionnaires from Business English Program students from Guangdong University of Foreign Studies to investigate the problems encountered and current situation of Business English Program in China. From the statistical analysis of the questionnaires, it finds: (1) employment and interest are the main reasons that students choose Business English as their major, but the current Business English teaching materials haven’t fully considered student’s demands for vocational requirements; (2) it should take into account both the learners’ and societies’ needs in Business English curriculum arrangement to increase the number of business-related courses appropriately; (3) students generally agreed that they lacks business knowledge and skills, so Business English courses should focus on cultivating the practical business skills; (4) Business English teaching materials should always be practicality oriented and targeted and communicative; (5) in order to improve teaching effectiveness, Business English teachers should consciously adopt different teaching methods targeted for different teaching content during the teaching process; (6) teachers’ morality, knowledge, teaching style and mutual relationship with students can be further enhanced to meet the needs of students.
Awareness, Training Needs and Constraints on Fishing Technologies among Small Scale Fishermen in Ondo State, Nigeria
Authors: Ogunremi Joshua Babatunde
Published: May 2016

The role of fishing technologies in achieving the National goal of food sufficiency cannot be over emphasized. Many small scale fishermen who are supposed to be the end users of various modern fishing technologies are ignorant of various technological opportunities they stand to gain in their profession. Therefore, the objective of the study was to determine the awareness, training needs and constraints on fishing technologies among small scale fishermen in Ondo State, Nigeria. A multistage random sampling procedure was employed to select three local Government areas (Irele, Ilaje and Ese-odo), six fishing communities, and twelve artisanal fishermen to get a sample size of 216. Data were collected from the respondents using structured interview schedule and analyzed through the use of descriptive and inferential statistical tools. The results revealed that most of the artisanal fishermen were aware of the fishing technologies and 82.4% indicated favourable training needs towards fishing technologies. Major constraints experienced by the respondents were lack of proper net maintenance (76.9%), limited outboard engine repair workshop (73.6%) and effective fish processing, preservation techniques and equipment (70.4%). Significant relationship existed between awareness and training needs on fabrication of low cost fishing gears (X2 = 18.48; p < 0.00), smoking oven (X2 = 15.77; p < 0.00) and outboard engine repairs (X2 = 5.47; p < 0.01). Based on the findings of the study, concerted efforts should be made by all stakeholders to ensure that the required training needs of artisanal fishermen are met for the sustenance of fisheries technologies.
