Parent selection for cocoa resistance to witches'-broom

The objective of this work was to identify genotypes with high general combining ability for resistance to witches'-broom (Moniliophthora perniciosa) in populations formed from a first cycle of recurrent selection. Highly productive and resistant clones from different origins were interbred using the North Carolina II design. The clones SCA 6, CSUL 7, RB 39, CEPEC 89, OC 67, BE 4, EEG 29 and ICS 98 were used as paternal parents, while the maternal ones were NA 33, CCN 10, IMC 67, P 4B, CCN 51, CEPEC 86, SGU 54 and ICS 9. Twenty days after germination, 56 seedlings of each cross (four replicates of 14 seedlings) received the inoculation of a 1-mL suspension with 7.5x104 basidiospores mL-1. Symptoms were evaluated 60 days after inoculation. Significant differences were observed among paternal and among maternal parents, for resistance to witches'-broom assessed according to the proportion of progeny seedlings with the disease symptoms. Differences were also observed between groups of mothers or fathers previously defined as resistant, and groups previously defined as susceptible. It is possible to obtain a combination of genes that can increase the level of resistance to witches'-broom directly from the first cycle of recurrent selection.
Carotenoid Components in Soybean Seeds Varying with Seed Color and Maturation Stage

The difference in carotenoid components among various color types of soybean seeds, and the changes in carotenoid composition during seed development were examined by reverse-phase high-performance liquid chromatogrphy (HPLC). Lutein was the major carotenoid component in seed extracts from the common yellow soybean and from a variety having a black seed coat. Green soybean seeds contained several xanthophylls in addition to lutein. None of the mature soybean seeds contained β-carotene, a part from a trace amount being detected in a local variety of green soybean. The total carotenoid and lutein contents were higher in green soybeans than in the yellow types, and the estimated total amount of carotenoids correlates with that of chlorophylls. The thylakoid membrane residue in the plastids of green soybean had lost its functional lamella structure. Immature soybean seeds contained a green-vegetable type of carotenoids including α- and β-carotene. The amount of β-carotene decreased more rapidly than that of l.
Hypoxia-Inducible Factor-1α Accumulation in the Brain after Experimental Intracerebral Hemorrhage

Hypoxia-inducible factor-1 (HIF-1), a transcription factor composed of HIF-1α and HIF-1β protein subunits, has been implicated in cellular protection and cell death in cerebral ischemia. The extent to which HIF-1 plays a role in brain pathology during intracerebral hemorrhage (ICH) is unknown. This study determined whether HIF-1α is upregulated at different time points in a rat model of ICH and the role of thrombin and red blood cell lysis in upregulation. Recently, thrombin has been implicated as a nonhypoxic regulator of HIF-1α in cultured smooth-muscle cells. Male Sprague-Dawley rats received intracerebral infusions of saline, autologous whole blood, blood plus hirudin, thrombin, thrombin plus hirudin, or lysed erythrocytes. Rats were killed at different time points for Western blot analysis, immunohistochemistry, immunofluorescent double staining, and reverse transcription polymerase chain reaction measurements of HIF-1α. HIF-1α protein levels increased without changing HIF-1α messenger RNA levels after intracerebral infusions of blood, thrombin, and lysed erythrocytes. HIF-1α positive cells, which proved to be neurons, were found in the brain after ICH. Hirudin, a specific thrombin inhibitor, reduced HIF-1α upregulation in response to both thrombin and blood. This study demonstrates that perihematomal HIF-1α protein is upregulated after ICH. This phenomenon is an early response of brain parenchyma to the clot. Thrombin and erythrocyte lysate are involved in HIF-1α upregulation through reducing HIF-1α degradation.
Schistonchus fistulosus n. sp. (Nematoda: Aphelenchoididae) associated with Ficus fistulosa in China.

A new nematode species was recovered from syconia of Ficus fistulosa from the South China Botanical Garden, Chinese Academy of Sciences, Guangzhou, Guangdong Province, China, during a survey of nematode biodiversity from 2007 to 2012. It is described herein as Schistonchus fistulosus n. sp. and is typologically characterised by possessing the combined characters of a long post-uterine sac, excretory pore located near the metacorpus, amoeboid sperm, three pairs of subventral papillae on the male tail, a mucron on the male tail tip, absence of a gubernaculum and possession of ox-horn-shaped spicules without a terminal cucullus and with a short, broad and bluntly rounded rostrum. Schistonchus fistulosus n. sp. was easily differentiated from other sequenced species by the partial small subunit rRNA gene (SSU) and D3 expansion segments of the large subunit rRNA gene (LSU). Phylogenetic analysis with partial SSU sequences suggests that S. fistulosus n. sp. has a closer relationship with S. guangzhouensis and S. baculum in the same highly supported monophyletic clade than to the other sequenced Schistonchus species. Based upon inferences using LSU D3 sequence data, it is also in a well-supported monophyletic clade with S. guangzhouensis and S. baculum.
Precipitation prediction using recurrent neural networks and long short-term memory

Prediction of meteorological variables such as precipitation, temperature, wind speed, and solar radiation is beneficial for human life. The variable observations data is available from time to time for more than thirty years, scattered each observation station makes the opportunity to map patterns into predictions. However, the complexity of weather variables is very high, one of which is influenced by Decadal phenomena such as El-Nino Southern Oscillation and IOD. Weather predictions can be reviewed for the duration, prediction variables, and observation stations. This research proposed precipitation prediction using recurrent neural networks and long short-term memory. Experiments were carried out using the prediction duration factor, the period as a feature and the amount of data set used, and the optimization model. The results showed that the time-lapse as a shorter feature gives good accuracy. Also, the duration of weekly predictions provides more accuracy than monthly, which is 85.71% compared to 83.33% of the validation data.
Recycling of Vulcanized Rubber Waste to Cationic Exchanger

Introduction Environmental pollution problem has become the focus of attention of various world countries, especially, scientific research centers have found that most environmental problems dating back to the increasing population growth [1]. With an increase in the population and an increase in consumption that is inevitably associated with an increase in the amount of waste left by the population, the importance of finding ways to dispose of it using useful scientific methods increases. It is no longer acceptable to dispose of solid waste by random means, and man can no longer be against nature. Rather, he must take on the role of the caretaker and the person responsible for protecting it [2]. Rubber is one of the most manufactured waste that needs to be recycled and reused. The most important source of rubber waste is worn rubber tires, whose massive expansion in the manufacture of cars and accessories is the main reason for their accumulation [3]. Several methods were used to get rid of them. The first attempts were based on simple methods of treatment for use in fields that do not require high specifications [4]. Pyrolysis methods were used to convert rubber into fuel and to produce black carbon [5], Recently, chemical treatments of vulcanized rubber waste have been carried out in order to prepare ion exchangers [6,7]. Ion exchangers are substances that are practically not soluble in water, which have a geometric structure that is fixed by equivalent bonds, it carries a functional Abstract Waste rubber wheels, are a wealth in industrialized countries and in some countries that have been able to devise scientific ways to take advantage of them. We have studied a transformation the vulcanized rubber waste (car rims) into cationic exchanger. The rubber waste is milled into small pieces except the layer containing the steel wire, then processed with sulfuric acid and toluene to insert aromatic toluene rings to the double bonds found in polybutadiene and polyisoprene, which represent about half the weight of the wheel. The next stage is the sulfonization of the aromatic rings produced with smoked sulfuric acid (oleum), thereby obtaining a cationic exchanger. Some chemical-physical properties of the prepared exchanger (acid capacity, exchange capacity, distribution coefficients, water of bloating, stability of the exchanger towards reactivation processes) were studied. The prepared exchanger is characterized by good acidic and reciprocal capacity and stability towards reactivation processes.
Spatial Scaling in Ecology

Acts in what Hutchinson (1965) has called the 'ecological theatre' are played out on various scales of space and time. To understand the drama, we must view it on the appropriate scale. Plant ecologists long ago recognized the importance of sampling scale in their descriptions of the dispersion or distribution of species (e.g. Greig-Smith, 1952). However, many ecologists have behaved as if patterns and the processes that produce them are insensitive to differences in scale and have designed their studies with little explicit attention to scale. Kareiva & Andersen (1988) surveyed nearly 100 field experiments in community ecology and found that half were conducted on plots no larger than 1 m in diameter, despite considerable differences in the sizes and types of organisms studied. Investigators addressing the same questions have often conducted their studies on quite different scales. Not surprisingly, their findings have not always matched, and arguments have ensued. The disagreements among conservation biologists over the optimal design of nature reserves (see Simberloff, 1988) are at least partly due to a failure to appreciate scaling differences among organisms. Controversies about the role of competition in structuring animal communities (Schoener, 1982; Wiens, 1983, 1989) or about the degree of coevolution in communities (Connell, 1980; Roughgarden, 1983) may reflect the
2,3,4,6-tetra-O-Acetyl-D-Gluconic Acid: Crystal Structure and Application in the Synthesis of N-(D-gluconyl) Derivatives of D-Glucosamine

2,3,4,6-tetra-O-Acetyl-D-gluconic acid was synthesized and coupled with 1,3,4, 6-tetra-O-acetyl-2-amino-2-deoxy-β-D-glucopyranose and diosgenyl 3,4,6-tri-O-acetyl-2-amino-2-deoxy-β-D-glucopyranoside to afford N-gluconyl derivatives of diosgenyl 2-amino-2-deoxy-D-glucopyranoside using the methods of solution-phase peptide synthesis. Both coupling reactions suffered from acetyl O→N migration, which caused the N-acetyl derivatives to be formed together with the N-(D-gluconyl) derivatives of D-glucosamine. Additionally, single-crystal X-ray diffraction and high-resolution NMR spectral data for 2,3,4,6-tetra-O-acetyl-D-gluconic acid were analyzed to reveal that this acyclic carbohydrate has adopted the 2G− conformation instead of a typical zigzag conformation. The planarity and cis geometry of the acetoxyl groups are demonstrated.
Database Benchmarking for Supporting Real-Time Interactive Querying of Large Data

In this paper, we present a new benchmark to validate the suitability of database systems for interactive visualization workloads. While there exist proposals for evaluating database systems on interactive data exploration workloads, none rely on real user traces for database benchmarking. To this end, our long term goal is to collect user traces that represent workloads with different exploration characteristics. In this paper, we present an initial benchmark that focuses on "crossfilter"-style applications, which are a popular interaction type for data exploration and a particularly demanding scenario for testing database system performance. We make our benchmark materials, including input datasets, interaction sequences, corresponding SQL queries, and analysis code, freely available as a community resource, to foster further research in this area: https://osf.io/9xerb/? view_only=81de1a3f99d04529b6b173a3bd5b4d23.
Characteristics of microbial fermentation and potential digestibility of fiber in the hindgut of dugongs (Dugong dugon)

The number of microorganisms in the hindgut of dugongs (Dugong dugon) were estimated and their in vitro volatile fatty acid (VFA) production and degradation of eelgrass measured. Scanning electron microscopy showed that some rod bacteria attached to the surface of plant tissue degraded and eroded the cell walls. Number of starch-, lactate-, cellobiose-, pectin-, xylan- and cellulose-utilizing bacteria, sulfate-reducing bacteria and methane-producing bacteria were estimated at 109 ∼ 1010 colony forming units g−1. Microorganisms degraded the cellulose and noncellulolytic components of the eelgrass, and about 47.3% of dry matter was degraded after 36 h in vitro incubation. The total VFA concentration was 10.5 mmol dL−1 at 36 h incubation, which included 55.7 mol% acetate, 18.0 mol% n-butyrate and 15.1 mol% propionate. The gas composition of in vitro fermentation was 68.4% carbon dioxide, 22.2% methane and 9.4% hydrogen.
A 2020 review on the role of procalcitonin in different clinical settings: an update conducted with the tools of the Evidence Based Laboratory Medicine

Biomarkers to guide antibiotic treatment decisions have been proposed as an effective way to enhancing a more appropriate use of antibiotics. As a biomarker, procalcitonin (PCT) has been found to have good specificity to distinguish bacterial from non-bacterial inflammations. Decisions regarding antibiotic use in an individual patient are complex and should be based on the pre-test probability for bacterial infection, the severity of presentation and the results of PCT serum concentration. In the context of a high pre-test probability for bacterial infections and/or a high-risk patient with sepsis, monitoring of PCT over time helps to track the resolution of infection and decisions regarding early stop of antibiotic treatment. As outlined by the Evidence Based Laboratory Medicine (EBLM), not only the pre-test probability but also the positive likelihood ratio influence the performance of a test do be really diagnostic. This aspect should be taken into account in the interpretation of the results of clinical trials evaluating the performance of PCT in guiding antibiotic therapy.
Analysis of Riau Traditional Games Based on Ethnomatematics in Developing Mathematical Capabilities of Elementary School Students

The purpose of this study was to analysis of riau traditional games based on ethnomatematics in developing mathematical capabilities of elementary school students. This adopts qualitative methods of the type of realist ethnography revealed in the narrative. The data was collected through observations, interviews, and documentation. In the study, it was found that some difficulties are faced by students who are less able to connect the learning in the classroom with their environment so that teacher needs effort in packaging learning to improve student interest and motivation. Factors that make students difficult consist of internal factors (motivation and self-nature of students) and external factors (the use of learning approaches/strategies, media and learning resources that arouse student interest). Whereas teacher was found to connect the mathematic learning with traditional game pacu jalur as one of Riau culture.
ANECHOIC CHAMBER MEASUREMENTS FOR CIRCULAR ISAR IMAGING AT MERSIN UNIVERSITY’S MEATRC LAB

Inverse synthetic aperture radar (ISAR) imaging is a reliable detection and classification technique for maneuvering targets at near and far-field ranges. In this study, we examine the near-field circular (turntable) ISAR imaging by conducting various real measurement experiments that were performed in the microwave anechoic chamber of the Mersin University’s MEATRC laboratory. The backscattered data were collected via a vector network analyzer that works as a Stepped Frequency Continuous Wave (SFCW) radar and for a number of simple and complex metal objects. The collected raw data were calibrated by using the backscattering data of a canonical object and then focused by applying a near-field backprojection image reconstruction algorithm. The resultant circular ISAR images demonstrate successful and well localized detection of various types of targets even though they are camouflaged by clothing. The obtained results reveal the preliminary efficacy of C band ISAR imaging in concealed object detection problem encountered at security checkpoints such as airports.
Effects of Dietary Supplementation of Two Commercial Plant Extracts on the Growth Performance and Ileal Inflammation Score in Broiler Chickens

We studied the effects on the performance and intestinal health of broiler chickens who were given Macleaya cordata (M. cordata) extract alone and those given a newly developed plant extract mixture (PEM) as a natural feed additive in the diet. Total 240 Ross 308 male chicks were used in this study and divided into 4 groups of 60 chicks each. For the experimental groups, 100 ppm PEM was added to the diet of group I (PEM 100); 200 ppm PEM was added for group II (PEM 200), and 18 ppm M. cordata extract (MCE) was added for group III. Although there were no significant differences in the feed conversion ratio, carcass weight, and carcass yield, other performance variables, including body weight, body weight gain, and feed intake were significantly affected. An analysis of the data from this study showed that specified feed additives decreased the ileal inflammation score without changing the villus height in the duodenum of the chickens. In conclusion, dietary supplementation of MCE supplement alone and the effects of newly developed PEM improved the performance parameters. Moreover, it can be said that it has an intestinal inflammation-reducing effect. Thus, this supplementation may have the potential to improve intestinal health.
Agronomic studies on pigeon pea (Cajanus cajan (L.) Millsp.) III.* Responses to defoliation

Two early-maturing and two late-maturing accessions of Cajanus cajan grown in the field for 161 days were defoliated to 90 cm ‘stubbles’ every 4, 8, 12 or 16 weeks over a period of 72 weeks. Evidence from total and seasonal dry matter and nitrogen yields, stand survival, and stubble yield at the termination of the experiment suggested that 8- and 12-week defoliation frequencies could be successfully integrated to incorporate cattle grazing and forage and seed production into a single management system. The late-maturing accessions were shown clearly to be better adapted to cutting, provided that basal green leaves always remained on the stubble. Defoliation of the accession UQ50 to reduce plant height to facilitate subsequent harvesting led to a reduced annual seed yield. The first seed crop was lost, as ‘topping’ removed the reproductive material.
Short-term effects of habitat fragmentation on the abundance and species richness of beetles in experimental alfalfa micro-landscapes

La perdida y fragmentacion del habitat han sido consideradas como las principales causas de la disminucion de biodiversidad. La perdida de habitat es una disminucion del habitat utilizable por los organismos y la fragmentacion es un cambio en la configuracion espacial del paisaje, donde los fragmentos remanentes quedan relativamente aislados entre si. Trabajos teoricos recientes indican que los efectos de la perdida de habitat son mas importantes que los de la fragmentacion, sin embargo existen pocos estudios experimentales que evaluen por separado ambos procesos. Para estudiar los efectos de la fragmentacion per se sobre la abundancia y riqueza de especies de coleopteros epigeos, se crearon 15 micro-paisajes de alfalfa de 30 x 30 m distribuidos en tres bloques. Doce de ellos se fragmentaron removiendo el 84 % del habitat, dejando cuatro o 16 fragmentos separados por 2 o 6 m. Entre diciembre del 2002 y abril del 2003, antes y despues de la fragmentacion, se muestrearon los coleopteros mediante trampas Barber. Se capturo un total de 8.074 coleopteros de 75 especies pertenecientes a 16 familias. El tipo de paisaje no afecto la abundancia de coleopteros, solo Anthicidae fue mas abundante en los paisajes de 4 fragmentos separados por 2 m y fue mas abundante en la matriz. El resto de de las familias fue mas abundante en los fragmentos, significativamente Carabidae y Lathridiidae. La riqueza de especies por trampa y por paisaje fue mayor en los paisajes con 16 fragmentos separados por 6 m, concentrandose en los fragmentos. Contrario a lo descrito en la mayor parte de la literatura, la fragmentacion no afecto negativamente la abundancia y riqueza de especies de coleopteros epigeos asociados a alfalfa. Mas bien, fragmentos de alfalfa mas pequenos y aislados ofrecieron un refugio de habitat para la biodiversidad de coleopteros epigeos. Estos resultados concuerdan con los postulados mas recientes que indican que la fragmentacion per se puede no tener efectos sobre la biota, o incluso puede favorecerla, al menos en el corto plazo
