Mass Production of Striped Patao Eugerres brasilianus Juveniles in Cuba

Abstract. — Two spawning and larval rearing trials with striped patao Eugerres brasilianus were conducted at Tunas de Zaza, Cuba, to develop a method for experimental-scale mass production of juvenile fish. Mature striped patao were captured from coastal lagoons in September 1988 and January 1989. Sexually mature females and males were induced to spawn by treatment with human chorionic gonadotropin (HCG). After spawning, eggs were collected and placed in 1.2-m3 cylindroconical fiberglass incubators at densities of 150 and 200 eggs/L. About 1 h before hatching, eggs were transferred to 5–m3 concrete tanks. Larvae were fed a mixture of marine microalgae, rotifers, copepods, and Artemia nauplii; artificial food was supplied at 30 d post-hatch as a shrimp diet with 25% protein and 0.1–0.4 mm particles. Fourteen of 20 females spawned after 2 or 3 HCG injections (total dose = 6–10 IU/g body weight). Fecundity was 467–2,167 eggs/g body weight. Egg incubation time in seawater (38–39 ppt salinity) was 15–17 h at 29–30 C and 21–23 h at 25–26 C, with 98–100% hatching rate. The oil droplet and yolk sac were consumed by 3 to 5 d post-hatch and first food (rotifers) was eaten during second day. High larval mortalities began after the first month. Growth in 39- ppt seawater was faster (0.41 ± 0.01 md/d) at 29.1 ± 0.3 C than at 25.2 ± 0.2 C (0.27 ± 0.008 mm/d). Overall survival was 6–12.5% with tinal densities of 5–10 juveniles/L after 48–60 d. A total of 132,000 juveniles was harvested from the two rearing cycles.
A Rapid Appraisal of Poor Educational Performance in Selected Secondary Schools in Navakholo Constituency in Kenya

Educational performance at any level of learning is a multi-variate function influenced by various factors such as access and enrolment to schools, schools ability to keep students in school till completion, actual academic couching and holistic guiding and counselling of the learners. Educational performance in Navakholo constituency in Kenya has been on a decline for during the past five to ten years. The cause of this observation was the gist of this study with the hope that insights from the research would help reverse the trend. Data was collected using a structured questionnaire administered to 170 boys and girls from two schools purposively sampled as they largely represent the outlook of most of the schools in the constituency. Results showed that other factors rather than access, enrolment and retention are responsible for poor performance in national examinations. Limited targeted academic mentorship, inadequate learning resources, internal school culture and student-related challenges were particularly singled out. A multi-stakeholder and integrated approach is necessary toward enhancing student completion and performance in their studies. This paper discusses specifics in this regard.

Fatigue Performance Test and Life Calculation of Fiber-Reinforced Asphalt Concrete

Received: 17 December 2019 Accepted: 25 February 2020 This paper aims to accurately measure the fatigue performance and calculate the fatigue life of fiber-reinforced asphalt concrete (FRAC). Firstly, splitting fatigue tests were conducted under the stress control mode. Through the tests, the attenuation features of the FRAC stiffness modulus were analyzed with different fiber contents and length-todiameter ratios. Drawing on damage mechanics theory, a fatigue failure criterion was put forward for the FRAC. Based on stress ratiofatigue life (S-N) equation, the authors established a calculation model for fatigue life of the FRAC, in the light of the characteristic parameter of fiber content (FCCP). The results show that, the FCCP can reflect the combined effect of fiber content and length-to-diameter ratio on the fatigue performance of the FRAC; With the growth of the FCCP, the FRAC fatigue life always increased first and then decreased; The FRAC realized the longest fatigue life, and achieved the best fatigue performance at the FCCP of 1.13; For AC-13 polyester FRAC (PFAC), the fiber content, length-to-diameter ratio, and the FCCP were optimized as 0.35%, 324, and 1.13, respectively. The research results provide new insights to the fatigue performance of the FRAC.
Fructan biosynthesis and fructosyltransferase evolution: Expression of the 6-SFT (sucrose : fructan 6-fructosyltransferase) gene in crested wheatgrass (Agropyron cristatum)

Summary Crested wheatgrass ( Agropyron cristatum ), an important cool-season grass, contains a complexity of fructans, including levans, inulins and graminans. Fructan types are characterized by unique combinations of carbon-carbon linkages. This study established the DNA sequence for the 6-SFT gene (sucrose : fructan 6-fructosyltransferase) in A. cristatum and compared the sequence with invertases and fructosyltransferases from various species. Detachment with illumination, as well as cool treatment of crested wheatgrass leaves induced the accumulation of fructans. All three types of fructans, β-2,1; β-2,6 and graminans (combination of both β-2,1 and β-2,6 linkages) were detected. The cDNA of 6-SFT was cloned from A. cristatum . The deduced amino acid sequences showed 85 percnt; identity with barley ( Hordeum vulgare ) 6-SFT. It also exhibited high homology with other fructosyltransferases and invertases. The expression of 6-SFT mRNA was analyzed with Northern hybridization. mRNA of the 6-SFT gene accumulated after 8 h of illumination in detached leaves and remained at a steady state for 36 hours. Under low temperature (10 °C/5 °C, day/night), the mRNA of 6-SFT began to accumulate after 8 h and reached the highest level at 2 d and then declined after 8 days of treatment. A coincidence of fructan and 6-SFT mRNA accumulation in crested wheatgrass suggests that 6-SFT has a role in fructan biosynthesis. A cladogram comparison of the amino acid sequences of most known sequences of fructosyltransferases and 23 invertases shows separations into various clades of like genes. 6-SFT does not contain the unique NDPNG amino acid sequence characteristic of invertases. Sequence analysis indicated that fructosyltransferases likely evolved separately in dicot and monocot species.
The molecular basis of selective DNA binding by the BRG1 AT-hook and bromodomain

The ATP-dependent BAF chromatin remodeling complex plays a critical role in gene regulation by modulating chromatin architecture, and is frequently mutated in cancer. Indeed, subunits of the BAF complex are found to be mutated in>20% of human tumors. The mechanism by which BAF properly navigates chromatin is not fully understood, but is thought to involve a multivalent network of histone and DNA contacts. We previously identified a composite domain in the BRG1 ATPase subunit that is capable of associating with both histones and DNA in a multivalent manner. Mapping the DNA binding pocket revealed that it contains several cancer mutations. Here, we utilize SELEX-seq to investigate the DNA specificity of this composite domain and NMR spectroscopy and molecular modelling to determine the structural basis of DNA binding. Finally, we demonstrate that cancer mutations in this domain alter the mode of DNA association.
VirtualCom: a simulation model for eco‐evolutionary community assembly and invasion

What is the relative importance of environmental filtering and competition in community assembly and invasion? At large spatial scales and for species‐rich systems, this question can be answered by studying functional and phylogenetic diversity patterns. The greater availability of community composition surveys, functional trait data bases and/or phylogenies from across a wide range of ecosystems has led to a significant increase in studies based on the analysis of diversity patterns. However, the underlying conceptual and methodological assumptions have recently been put into question, requiring rigorous evaluation of their reliability. In order to test these underlying assumptions, we need to be able to compare diversity patterns with their true underlying processes. For empirical data, we usually do not know these underlying processes, but for virtual data generated by simulation models, this information is available. Using two illustrative examples, we introduce VirtualCom, a simulation model that generates such data sets. Integrating both ecological and evolutionary processes, VirtualCom simulates the evolution of the pool of regionally occurring species, the process‐based assembly of native communities and the invasion of novel species into native communities. The model provides functionalities for a variety of processes. Most importantly, in the simulation of the species pool, different trait evolution models allow the generation of clustered and random trait distributions in the phylogeny (resulting in varying strength of phylogenetic signal). Additionally, when the species assemble from the species pool into local communities based on their trait values, the relative strength of environmental filtering and competition can be set independently. By offering possibilities for a broad range of simulation‐based modelling experiments, VirtualCom is a simple and readily usable tool that will help to resolve theoretical and methodological issues in community ecology.
Forage Yield and Soil Characteristics Under Various Crops in Alaska

Forage crops and soil attributes were evaluated for 4 years at three sites in Alaska. Annual herbage yields usually exceeded 5 Mg ha-1 on neutral soils at Fairbanks (64°52' W) and on moderately acidic soils at Point MacKenzie (61°24' N, 150°3' W). Strongly acidic, droughty soils at Delta Junction (63°55' N, 145°20' W) produced low yields for all crops. Soil pH decreased significantly over 4 years under N-fertilized grasses at Delta Junction and under alfalfa and N-fertilized barley at Fairbanks. Soil organic C and N and microbial biomass C showed no differences among treatments at the end of the study. Wet aggregate stability did not vary significantly among crops but was lower for fallow. The results of this study indicated a high potential for use of perennial forage legumes at some locations in Alaska. The lack of large differences in most soil parameters indicates slow responsiveness to management by some commonly used soilquality indicators under subarctic conditions.
ICTS AND ECONOMIC GROWTH IN AFRICAN COUNTRIES

It is well established that Information and Communications Technologies (ICTs) are strong drivers for economic growth. While many studies have shown the strong correlation between ICT and economic development in a number of developed and developing countries, little research has been done on African countries in general and Nigeria in particular. This paper is aimed at identifying the relationship between ICT and economic growth in order to provide the way forward for Nigeria to use ICT for economic development. An analysis of the actual relationship between ICT and economic growth is made which identifies the necessary as well as sufficient factors that provide the catalyst to turn ICTs into drivers for economic growth. This is used to explain why the use of ICTs in many African countries does not result in the desired economic growth. A broad discussion is provided on the use of ICTs as a service sector as well as an economic sector. It is obvious that while both sectors can lead to economic growth, developing countries that use ICT as an economic sector are likely to do much better in generating wealth and providing job opportunities. A broad survey is made of the use of ICTs in Africa with particular emphasis to the experiences of a few countries namely Botswana, Mauritius, Egypt and South Africa. An attempt is then made to bring out the true relationship between ICTs and economic growth by analyzing the theoretical models on the major factors that drive ICTs in bringing about economic growth and emphasizing the way forward for countries that have not exploited ICTs as engines for economic growth.
Distribution and diversity of zoosporic fungi from soils of four vegetation types in New South Wales, Australia

Chytrids are common microfungi in soils, but their distribution and diversity in Australian soils is poorly described. In this study we analyzed chytrid distribution and diversity in soils from four collection sites representing a subtropical rain forest, wet sclerophyll forest, dry sclerophyll forest, and open heath, using a defined and reproducible sampling protocol. The greatest number of chytrid species was observed from dry sclerophyll forest soils, while the least number of species occurred in the open heath soils, although each soil sample of the open heath harbored more species per sample. Differences in patterns of distribution of chytrid species were statistically significant between subtropical rain forest and open heath. Patterns in other habitats differed but could not be verified statistically to be significant at the 5% level. Observed differences in chytrid distribution, diversity, and freqency indicate that their ecological strategies may be in response to environmental cues such as speci.
Correlation between the morpho-cytohistochemistry of the outer mantle epithelium of Anodonta cygnea with seasonal variations and following pollutant exposure

Seasonal and experimental conditions induce morphological and cytochemical variations in the outer mantle epithelium (OME) of the freshwater bivalve Anodonta cygnea, probably influencing the shell calcification mechanism. In this study, OME samples were taken from untreated animals in autumn, winter, spring and summer as well as from animals exposed to divalent metals (cadmium, chromium, lead, copper and zinc) and pesticides (setoxidim and dimethoate) and observed by light microscopy. The present results showed that OME cells have larger cell volumes and increased amounts of secreted macromolecules during spring and summer than in autumn and winter. This correlates with higher shell calcification rates in spring and summer and lower shell calcification rates in autumn and winter. The experiments showed that incubation with pollutants for 8 months dramatically reduced the cellular volume so that the density of cytoplasmic material appeared higher that in the control samples. The pronounced changes in OME cells suggest a significant decrease in secretory activity following exposure to toxic agents and this has implications for the shell calcification process.
Logical Framework Approach to Calabria Sustainable Development: The Intervention Program on School Buildings

Received: 2 October 2019 Accepted: 26 December 2019 Sustainable development is the main goal set at international, European and Italian level. Calabria Region has addressed the programming activities on the sustainable development articulated in its main components: environmental, economic and social. The program of school buildings implemented by Calabria Region has introduced the obligation of environmental sustainability and seismic certification for all public buildings or financed with public funds, giving a strong acceleration to the process of Calabria building sector in the direction of greater sustainability. This paper presents the case of the school building to underline the strong action made by the Region which consisted of: interventions of seismic adjustment only; unification of all spending programs that guarantee zero bureaucracy and maximum transparency; increase of knowledge through the construction of a database from which to find all the useful information relating to the interventions. In the paper is presented the logical framework approach (LFA) to design a viable path to sustainable development of the school model where, starting from financial resources (input), realizes quality schools (output) in order to pursue sustainable development (goal). The creation of quality schools implies impacts (outcomes) that can be positive or negative. The paper allows to analyze the quality impacts of the school program.
Synthesis between leadership behaviours and principal–agent theory

13‘Initiating structure’ and ‘consideration’ have long stood as broad dimensions of leadership behaviour. Recent theory and meta-analyses suggest a continued role for such constructs. However, this study asserts that initiating structure is best composed of two sub-constructs, namely a leadership focus on directing and controlling subordinate task behaviours versus a focus on outcomes. Ignoring this dualism has previously rendered initiating structure too broad a construct to facilitate meaningful hypotheses, and statistically the weaker of the constructs. This study uses principal–agent theory to support this split in theory, and presents initial structural equation modelling (SEM) tests to illustrate the superiority of a two-part initiating structure construct. Thereafter, a large number of research propositions are explored using the new dimensions, as well as two interesting case contexts. This respecifi cation allows for propositions more in line with prior empirical fi ndings, and fi ner examinations of relationships. 14
An investigation into the physical properties of fibre prepared from several carrot varieties at different stages of development

Important physical properties of dietary fibre include water holding capacity (WHC) and cation exchange capacity (CEC). In this investigation fibre prepared from different varieties of the same species, the carrot Daucus carota, have been sampled at different stages of development to determine whether these physical properties were dependent upon variety and the age of the plant. Results for WHC (g g−1 fibre) were dependent on the method of analysis. Differences found between varieties for WHC measured by centrifugation (mean 23.7 g, range 13.4–32.3) were not apparent when measured by filtration of a corresponding sample (mean 27.9 g, range 17.2–45.5). Differences between methods probably reflect structural differences in the fibre influenced by age and variety. Both methods showed carrot fibre to have a relatively high WHC. The CEC (meq g−1 fibre) was found to be similar between varieties but to increase with age within each variety, (mean 1.44 meq, range 1.07–2.42). The type of exchange did not change and the CEC 100 g−1 fresh carrot remained constant between varieties and also within each variety. The pK determined for each sample was between 4.42–5.30 which suggests pectins to be responsible for the CEC.
Multivariate Statistical Analysis of Atmospheric Dispersion of BTX Compounds at Sanathnagar, Hyderabad.

Sanathnagar, located in the centre of Hyderabad city, is taken as a case study to assess the meteorological factors influencing the air quality parameters Benzene, Toluene, Xylene (BTX compounds) and to identify the significant sources of pollution using the interspecies ratios. A data of ten years (20072017) from Central Pollution control board (CPCB), Hyderabad, Telangana state is studied. TX compounds coming under Volatile Organic Compounds (VOC) were considered as the air quality parameters, seasons as cases and concerning meteorological factors such as Atmospheric Temperature AT (C), Relative Humidity RH(%), Wind Speed WS (m/s), Wind Direction WD (deg), Sun Radiation SR (w/m), Barometric Pressure BP (mm/Hg). Multivariate statistical techniques, namely Principal Component Analysis (PCA), and Cluster Analysis are used in this study with the help of IBM SPSS 26. The KMO test sampling adequacy found to be higher than 0.5, and the Bartlett test showed lesser value than 0.00, hence proving the results of the analysis are satisfactory. From BTX ratios it was observed that T/B was much higher than one and X/B been minimal value for all seasons indicating traffic pollution as a significant source of ambient air pollution in the study area. On the other hand, the correlation matrix states that a positive correlation between meteorological factors and ambient air quality parameters are as follows: SRBenzene, Xylene; BPToluene; WSBenzene, Toluene, and Xylene and the factors with a negative correlation on parameters are WD, RH, AT. PCA states that ambient air quality parameters are influenced by meteorological factors such as SR, RH, WS, WD (major influencers) and BP, AT (moderator influencers). Whereas in Cluster Analysis major influencers are WS, AT, RH and moderate are WP, SR, BP respectively. Therefore, PCA and CA results have shown similar trends in the categorization of meteorological influencers.
