Evaluación técnica de la agregación de valor a partir de variedades de cebolla (Allium cepa) cultivadas al norte de la Región Central Oriental de Costa Rica
Authors: Brenes-Peralta Laura Patricia , Gamboa-Murillo Marianella , Segreda-Rodríguez Ana Cecilia 
Published: August 2019

El sector cebollero costarricense es dinámico y cuenta con una institucionalidad que respalda las acciones de investigación y extensión, como el Programa Nacional de Cebolla del Ministerio de Agricultura y Ganadería-MAG, las Agencias de Extensión Agropecuaria locales, y el Programa de Investigación y Transferencia de Tecnología Agropecuaria-PITTA Cebolla. Sin embargo, la comercialización en fresco de la cebolla enfrenta dificultades, por lo que este proyecto tuvo por objetivo “Evaluar el proceso de agregación de valor a variedades de cebolla (Allium cepa) cultivadas en zona Norte de la Región Central Oriental (al norte de Cartago). Se consideraron los materiales E515, Predator y Alvara, valorando dos variables principales para el análisis comparativo a partir de pruebas de valor agregado, considerando: tiempo de ejecución del proceso agroindustrial y rendimiento de producción. Las variedades Predator y E515 usualmente mostraron los rendimientos más altos y los menores tiempos de elaboración según el producto de valor agregado del que se tratara. Los resultados fueron transferidos a los beneficiarios en un taller teórico y tres sesiones prácticas en la Planta Piloto Agroindustrial del Instituto Tecnológico de Costa Rica (TEC). Se recomienda ahondar en investigaciones para validar los resultados hallados y se sugieren estudios de factibilidad específicos en el caso de desear incursionar en emprendimientos de este tipo.

Published: August 2019

Aim: The aim of the study was to evaluate the effects of five different oenological tannins on the color of a malvidin-3-O-monoglucoside solution, and thereby assess the effectiveness of these tannins as copigments.Methods and results: Solutions containing malvidin-3-O-glucoside and different doses of copigments were prepared. The malvidin-3-O-glucoside concentration of the solutions, and color parameters, were measured after 1 and 7 days.Conclusions: On days 1 and 7, a decrease in lightness and hue, and an increase in chroma, absorption at 520 nm and wavelength of maximal absorption were observed in solutions containing the oenological tannins. A decrease in malvidin-3-O-glucoside concentration in the tannin-containing solutions compared with the control solution was detected on day 7. The extent of this decrease depended on the specific tannin. Some changes in color parameters on day 7 compared with day 1 were observed, which were probably due to the formation of new pigments. The total color difference between the different malvidin-3-O-glucoside solutions and a pure white solution was calculated to estimate the effectiveness of the different tannins as copigments.Significance and impact of the study: These results prove that supplementation with oenological tannins is a viable option for improving the color of red wines. A copigmentation index is proposed for measurement of the effectiveness of copigments.

Published: August 2019

AbstractThis study of mid-Cretaceous foraminifera from the Linzhou, the Coqen and the Xigaze Basins in the southern Tibetan Plateau has provided the first high resolution biostratigraphic description of these limestones and interpretation of their paleoenvironmental settings. The fossil assemblages are dominated primarily by orbitolinid larger benthic foraminifera. We reassessed the identification of many taxa, dividing the South Tibetan sedimentary successions of Aptian to Early Cenomanian age into eight new foraminiferal biozones (TLK1 a–h): (i) (TLK1a) a shallow reefal environment corresponding to planktonic foraminifera zone (PZ) Aptian 1–2, dominated by Palorbitolina and Praeorbitolina spp.; (ii) (TLK1b) a transgressive, reefal to forereefal environment corresponding to PZ Aptian 3, characterized by the first appearance of Mesorbitolina parva; (iii) (TLK1c) a shallow reefal to backreef environment of Late Aptian (PZ Aptian 4) age, characterized by the first appearance of Mesorbitolina texana; (iv) (TLK1d) a transgressive phase of forereef to an inner neritic environment of Albian (PZ Albian 1) age, characterized by the first appearance of Cuneolina pavonia; (v) (TLKe) an open-marine reefal environment of Albian (PZ Albian 2) age, with assemblages dominated by flat to slightly conical orbitolinids, characterized by the first appearance of Palorbitolinoides hedini; (vi) (TLK1f) a shallow, open-marine reefal to forereef environment of Middle Albian (PZ Albian 3) age, dominated by flat and convex orbitolinids, and characterized by the first appearance of Mesorbitolina aperta; (vii) (TLK1g) a reefal to forereef environment of end Albian (PZ Albian 4) age, characterized by the appearance of Conicorbitolina cf. cuvillieri and Pseudochoffatella cuvillieri, and in which Early Aptian species of Praeorbitolina cf. wienandsi have been recorded for the first time from the Late Albian; (viii) (TLK1h) a shallow reefal environment of Early Cenomanian age characterized by the first appearance of Conicorbitolina sp. A and Nezzazata conica. The eight new biozones provided biostratigraphic correlation of the Langshan, Sangzugang and Takena Formations in the Lhasa terrane, while the observed evolution of the environmentally controlled microfacies corresponds closely with the current, inferred global sea-level variation of the period. The almost continuous sedimentary sequences studied allowed previously defined orbitolinid phylogenetic linages to be confirmed.
The Foraminifera of Chincoteague Bay, Assateague Island, and the Surrounding Areas: a Regional Distribution Study
Authors: Ellis Alisha M. , Shaw Jaimie E. , Osterman Lisa E. , Smith Christopher G., 
Published: August 2019

AbstractForaminiferal census data from Chincoteague Bay, Newport Bay, the salt marshes of Assateague Island, adjacent mainland salt marshes, and the inner-shelf, were assessed to determine the current assemblages in Chincoteague Bay, and how the different environments surrounding the bay, and the gradients within the bay, influence the microfossil distribution. Determining the current background distribution and its drivers allows for future comparisons to determine paleoenvironmental conditions, impacts from natural and anthropogenic pollution, and the influence of climate change. Foraminiferal census data were compared to sedimentological characteristics and environmental parameters, exhibiting strong correlations with salinity, sediment organic content, and grain-size. Foraminiferal distributions exhibited a gradient from an assemblage dominated by Elphidium cf. E. excavatum near Chincoteague inlet to an assemblage dominated by Ammonia parkinsoniana and Ammobaculites cf. Ab. exiguus in the more restricted central and northern portions of the bay. The sites closest to the mouth of Trappe Creek in Newport Bay, along the western side of Chincoteague Bay and in the central bay, had a greater relative abundance of dead agglutinated taxa compared with the majority of sites in Chincoteague Bay. Despite the overwhelming dominance of calcareous taxa throughout the bay, dissolution may affect the preservation potential of Cribroelphidium poeyanum and Haynesina germanica in the northern and central portions of Chincoteague Bay, as indicated by seasonal pH data. Similarly, the sandy back-barrier lagoonal sites exhibited relatively low densities, potentially a result of dissolution or mechanical destruction.
Calibration of Test Diameter and Area As Proxies For Body Size in the Planktonic Foraminifer Globoconella Puncticulata

Abstract
Body size is one of the most commonly measured traits in ecology and evolution because it covaries with environmental (e.g., temperature, latitude, degree of population isolation) and life-history (e.g., metabolic rate, generation time) traits. However, the driving mechanisms of body size variation in the distant geological past are poorly known and complicated by partial specimen recovery, limited population-level sampling, and the use of linear measurements as proxies for three-dimensional volumetric-size data. How much information are we missing by using approximate metrics of body size? Here we examine this question in an evolving lineage of planktonic foraminifera. We measure test diameter and surface area of over 500 individuals of the species Globoconella puncticulata using two-dimensional images. These results are compared with measurements of test volume of the same individuals as measured by a recently developed high-throughput method for analysing three-dimensional morphometrics as well as high-resolution three-dimensional computed tomography scanning. Our results show that even in a lineage showing substantial morphological change, a cross-sectional test area can provide a consistent proxy for body volume. Approximating body volume with one-dimensional (linear) size measurements is more problematic as it systematically over- and underestimates the smallest and largest tests, respectively. In our study, shape (here measured as shell-aspect ratio) only explained marginally more variation when included in the regressions. The use of 3D light microscopy introduces a small degree of scatter in the data, but the number of individuals necessary to detect trends in body size with sufficient statistical power is comparable to the sample size required for other traits. These results imply that even in an evolving lineage undergoing substantial morphological change, cross-sectional area can provide a consistent proxy for body size.
Two New Species of Recent and Upper Holocene Coccolith-agglutinated Foraminifera from the North Icelandic Shelf, North Atlantic
Authors: Perner Kerstin , Knudsen Karen-Luise 
Published: August 2019

AbstractTwo new coccolith-agglutinated foraminiferal species, Pseudobolivina islandica n. sp. and Haplophragmoides atlanticus n. sp., are described from Recent and Upper Holocene sediments at Húnaflóaáll on the North Icelandic shelf. Specimens of the two species have been found only in the small (63–106 µm) fraction using the wet-counting method. This method allows preservation of these fragile tests, which are predominantly composed of coccoliths, mainly of the species Coccolithus pelagicus (Wallich, 1877).

Published: August 2019

AbstractThis study documented surface distributions of live and dead foraminiferal assemblages in the low-gradient tidal marshes of the barrier island and estuarine complex of the eastern Mississippi Sound (Grand Bay, Pascagoula River, Fowl River, Dauphin Island). A total of 71,833 specimens representing 38 species were identified from a gradient of different elevation zones across the study area. We identified five live assemblages and nine biofacies for the dead assemblages from estuarine, low marsh, middle marsh, high marsh, and upland transition environments. Although dissolution of calcareous tests was observed in the dead assemblages, characteristic species and abundance patterns dependent on elevation in the intertidal zone were similar between living assemblages and dead biofacies. The assemblages from the eastern Mississippi Sound estuaries were dominated by Ammonia tepida, Cribroelphidium poeyanum, C. excavatum, and Paratrochammina simplissima. The low marshes were dominated by Ammotium salsum, Ammobaculites exiguus, and Miliammina fusca. The dominant species in the middle marshes was Arenoparrella mexicana. The most abundant species in the high marshes was Entzia macrescens. The upland–marsh transition zones were dominated by Trochamminita irregularis and Pseudothurammina limnetis. Canonical correspondence analysis was applied to assess the relationship between a priori defined biofacies and measured environmental data (elevation, grain size, organic matter, and salinity) to test the hypothesis that distribution of foraminiferal assemblages is driven by elevation and hence flooding frequency. Salinity was the second most important explanatory variable of dead assemblages. Riverine freshwater from the Pascagoula River markedly influenced the live and dead assemblages in the Pascagoula River marsh, which was represented by low diversity and densities and dominance by Ammoastuta inepta. The relationship between the measured environmental variables and assemblage distributions can be used in future Mississippi Sound paleo-environmental studies.

AbstractWe examined the abundances of two species of benthic foraminifera that host algal endosymbionts (SBF) in two sedimentary reefal areas (Pirangi and Maracajaú) of Rio Grande do Norte (RN, Brazil). The original dataset is based on 95 samples collected in winter in 2013 and 2014 by divers or grab samplers, and is compared to other known Brazilian reefs. The tests of Amphistegina gibbosa were conspicuous in sediments associated with coral and coral-rubble substrata, whereas tests of Amphisorus hemprichii were best represented in sediments associated with seagrass. Our studies also have revealed that populations of these species are depauperate near tourism sites in Pirangi, as the area is affected by trampling from tourist activities. In the Maracajaú area, these populations are healthier, except at sites severely affected by tourism. Differences in microhabitats of the two taxa are likely to be associated with the degree of anthropogenic influence on the inner shelf at Pirangi compared to the offshore Maracajaú area.
New Findings On an Orbitolinid Foraminifer Coskinolinella Bariensis (luperto-sinni & Reina, 1992) from the Albian Shallow-water Carbonate Sequence of the Bey Dağlari (s Turkey)
Authors: Tasli Kemal , Solak Cemile 
Published: August 2019

AbstractThe orbitolinid foraminifer Heterocoskinolina bariensis Luperto-Sinni & Reina, 1992, which was first described from the Cenomanian (lower?) of the Apulian Carbonate Platform (southern Italy), has also been found in a Cretaceous shallow-water carbonate sequence of the Bey Dağları Carbonate Platform (Western Taurides, southern Turkey). The morphological analysis, based on numerous successive acetate-peels, revealed annular chambers subdivided into wedge-like chamberlets ( = cupulae) by apparent “radial partitions” produced by the strong infolding of the chamber floor; these are characteristic of the genus Coskinolinella Delmas & Deloffre, 1961. Specimens were compared with descriptions and images of closely related taxa. The stratigraphic position of C. bariensis was determined as upper Albian, based on its occurrence 50 m below the lower–middle Cenomanian Sellialveolina gr. viallii Zone and the presence of Protochrysalidina elongata. Because of its restricted stratigraphic range, this species may have age-diagnostic value for Cretaceous biostratigraphy in restricted platform facies. Other benthic foraminifera, some poorly known, are also documented and illustrated from this same shallow-water carbonate sequence.
Rapid Change of Foraminiferal Communities and Assemblages in the Setiu Estuary, Terengganu, Malaysia: Anthropogenic Drivers

Published: August 2019

AbstractIn November 2013, an artificial inlet was opened in the barrier island that separates the waters of the Setiu estuary-lagoon system of Terengganu, Malaysia, from the South China Sea. The inlet was opened to stabilize salinity and improve tidal flushing so that fish-farming could be expanded but, as a result, another inlet that was open in 2009 closed naturally by November 2015. These geomorphic changes caused salinity in the Setiu estuary to undergo significant increase from November 2013 to November 2015.To investigate the foraminiferal response to these salinity changes, 24 of 56 foraminiferal sampling stations occupied in 2009 were resampled in 2016. Salinity increased throughout the estuary from 2009 (mean 6.6, range 0–28.7) to 2016 (mean 33.3, range 23.3–34.8) and foraminiferal live communities and dead assemblages changed. Diversity of dead assemblages increased significantly (mean number of species/sample in 2009 = 10.9 versus 2016 = 25.8) as the result of transport of specimens of nearshore, neritic species into the estuary through the new inlet. Diversity of live populations increased slightly (2008 = 4.6 versus 2016 = 6.2). Dead assemblages and live populations dominated by agglutinated foraminifera in 2009 were co-dominated by calcareous hyaline foraminifera in 2016. Live calcareous porcelaneous foraminifera were rare in 2009 and 2016, but dead miliolids were more common and more widespread in 2016. Stations in higher energy environments immediately adjacent to the two different inlets of 2009 and 2016 were characterized by few live or dead foraminiferal tests. Changes in foraminiferal diversity, abundance, and distribution between the two sampling times of early June 2009 and late May 2016 were significant and took place within the 30-month interval between November 2013 (when the artificial inlet was opened) and May 2016 when samples were collected, but they most likely occurred over a shorter interval of time.

Abstract
Objective: The objective of this study was to identify college facility related factors affecting medical students’ academic performance in human anatomy course.
Result: A total of 120 study participants were included in the study. Off which 81 (67.5%) were male while 39 (32.5%) were females. Dormitory crowdedness (AOR 3.16 (95% CI: 2.01-.83, p= 0.11), large class size (AOR = 2.36; 95%CI: 1.11- 4.64 p = 0.005), inadequate classroom facilities (AOR = 1.56; 95%CI: 1.51-4.91, p = 0.001), low internet access (AOR = 1.99; 95%CI: 1.07-3.22, p = 0.015) and inadequate anatomy teaching model (AOR = 2.63; 95%CI: 1.17 - 6.12, p =0.003) were significantly associated with low performance in human anatomy course exam. However, college library (AOR = 0.23; 95%CI: 0.1-0.48 p = 0.061) did not showed significant association with academic performance (p = 0.61). As a conclusion, dormitory crowdedness, large class size, inadequate classroom facilities, low internet access and inadequate anatomy-teaching models were independent factors, which affect performance of medical students in human anatomy course exam. However, there was no significant association between college library and performance of study participants in human anatomy course exam.
