Crystallization and textural evolution of a closed-system magma chamber: insights from a crystal size distribution study of the Lilloise layered intrusion, East Greenland

Abstract The recognition that postcumulus processes significantly modify primary textures in layered mafic intrusions has thrown into question many early observations on which classical crystallization theories are based. Petrographic observations combined with quantitative textural analysis of samples from various stratigraphic levels of the Lilloise intrusion, East Greenland, demonstrate that postcumulus textural modification of cumulates, formed during the solidification of a closed system magma chamber, may be detected. Crystal size distribution (CSD) measurements of Lilloise cumulates and the resulting CSD profiles are compared to predicted theoretical closed system CSD profiles. Similarities between the measured CSD profiles and published predicted CSD profiles support Lilloise magma evolving in a closed system chamber and indicate that primary crystallization processes can be distinguished using quantitative textural techniques. Textural coarsening driven by syn-magmatic deformation is suggested to be the dominant postcumulus process affecting CSD plot morphology. CSD slope values and profiles (plot shapes) remain relatively constant for a given liquidus mineral (particularly olivine and clinopyroxene), so that the number of phases on the liquidus at any one time affects mineral modal abundances. As a result, CSDs generally exhibit overall smaller grainsizes and progressively lower nucleation densities at higher levels in the intrusion.

This research is conducted to highlight the main risk factors in the delays of hydropower construction projects in Vietnam. The research employs the method of statistical calculations and risk analysis to obtain feedback from experts participating in similar projects. The research outcomes are as follows: identifying the risks that can cause delays in EPC hydroelectric construction projects in Vietnam; calculating and classifying the degree of impact of each risk to the progress of the construction. The practical significance of this study is to ensure the timely completion of projects, benefits for the investors, and the EPC general contractors.
Technical and Economic Evaluation of Three Types of Tomato Nutrient Solutions under Semi-Controlled Conditions

This study was conducted to evaluate the effect of three types of nutrient solutions on the development, performance, quality and cost of chonto tomato ( Solanum lycopersicum L.) under semi-controlled conditions. The assessment was conducted in the farm Tesorito, Manizales, Colombia. An experimental design was established in randomized complete blocks (RCB), with 3 treatments, 4 replicates per treatment and 10 effective plants per replicate. The variables were: height of the first cluster, production per plant, yield t ha-1 and qualities of the fruit. The economic variables were production costs, cost-benefit ratio (C/BR), rate of return (IRR) and net present value (NPV). In general, production per plant was greater than 4.7 kg plant -1 and the average yield was 92 t ha -1 . The use of conventional fertilization (tt2) generated increased production of premium quality fruit with a value of 37.11 t ha -1 , demonstrating that conventional soil fertilization implemented in this culture under semi-controlled conditions in the company of drip irrigation system in the root zone improve outcomes of productive variables, increasing profitability and competitiveness with a net profit of USD$ $ 25203.68 ha -1 , with average selling price of USD$ 0.45 per kilogram and a unit production margin of USD$ 0.21 per kilogram, making this technology attractive and economically viable.
Effects of Ulva rigida and Cystoseira barbata Meals as a Feed Additive on Growth Performance, Feed Utilization, and Body Composition of Nile Tilapia, Oreochromis niloticus

In a 12-week feeding trial, the effect of 2 algae meals (Ulva rigida or Cystoseira barbata) on feed intake, growth, and nutrient utilization of juvenile Nile tilapia, Oreochromis niloticus, was investigated. This was the first attempt to utilize Cystoseira barbata as a feed supplement for Nile tilapia. The fish were fed to apparent satiation with formulated diets supplemented with various levels of Ulva meal (5%, 10%, or 15%) or Cystoseira meal (5%, 10%, or 15%). A diet without algae meal served as a control diet. The highest values for weight gain were for fish fed the 5% Cystoseira diet, control diet, and 5% Ulva diet (156%, 151%, and 150%, respectively), but the values were not significantly different (P > 0.05) compared to other treatments, except for the fish fed on the 15% Ulva diet (P 0,05), en yuksek a¤›rl›k art›fl› deerleri s›ras›yla Cystoseira % 5, kontrol ve Ulva % 5 ile beslenen gruplarda kaydedilmifltir.

Composition and Abundance of Benthic Macro-invertebrates in Freshwater Earthen Ponds of Noakhali District, Bangladesh

The composition and abundance of benthic macro-invertebrates in freshwater fish ponds of Noakhali region were analyzed for a period of six month (December-May, 2012). Experimental ponds were categorized as culture, household and derelict and samples were drawn every week during the entire study period using an Eckman grab with dimension of 15.2×15.2×15.2 cm. A total of 10 major groups/taxa were identified viz.; Polychaetes, Oligochaetes, Gastropods, Amphipods, Bivalve, Diptera, Crab, Isopods, Prawn larvae and Copepod. Total macro-benthos abundance was recorded 1555.54, 1466.66 and 2177.79 ind. / m2 respectively in culture, household and derelict ponds. Oligochaetes were found dominant (49 -75%) in all the experimental ponds. Density of Oligochaetes was recorded 888.89, 1088.89 and 1066.67 ind. /m2 respectively in culture, household and derelict ponds. The overall composition of macro-benthos was Polychaetes (9.19%), Oligochaetes (58.56%), Gastropods (19.23%), Amphipods (3.85%), Bivalvia (1.50%), Diptera (1%), Crab (0.43%), Isopods (0.43%), Prawn larvae (0.21%) and Copepods (0.85%). The present study reveals that macrobenthic fauna and their density are variable among the freshwater ponds. The obtained information can be used for further analysis of seasonal variation of macrobenthos, conserve biodiversity and seasonal change of water quality parameter of freshwater ponds.
Living kidney transplantation: beyond immunological barriers

Although criteria for living kidney donations have greatly evolved in recent years with acceptance of related and unrelated donors, an immunological incompatibility, between a living donor and his intended recipient, could impede up to 40% of such procedures. To avoid refusal of willing and healthy living donors, different strategies have emerged to overcome immunological incompatibilities. ABO incompatible kidney transplantation can now be achieved with identical outcomes to compatible/identical kidney transplantation and kidney paired donation is the safest way for HLA-incompatible patients to undergo kidney transplantation. Implemented with success in many countries either as national or multiple regional independent programs, kidney paired donation could include simple exchanges between any number of incompatible pairs, incorporate compatible pairs and non-directed donors to start a chain of compatible transplantations, lead to acceptance of ABO-incompatible matching, and integrate desensitizing protocols. Incorporating all these variations, kidney paired donation has been able to facilitate kidney transplantation in up to 49% of registered patients from incompatible pairs.
Tales of the unexpected: Integrating career shocks in the contemporary careers literature

Orientation: This article addresses the interplay between individual agency and contextual factors in contemporary career development processes. In light of the prominence of the former in the contemporary scholarly debate, we present a case for a more comprehensive approach by heeding the latter as well. Research purpose: The main aim of this article was to provide a definition and conceptualisation of career shocks, as well as an agenda for future research on this topic. Motivation for the study: Most of the contemporary careers literature has overemphasised the role of individual agency in career development. While certainly important, we argue that we also need to address the role of context – in this case, career shocks – in order to gain a fuller appreciation of career development processes. Main conclusions and implications: We provide a definition of career shocks based on the existing literature related to chance events and turnover. In addition, we provide an overview of attributes of career shocks, potentially valuable theoretical perspectives and key issues for future research. Contribution: This article brings together several existing streams of literature related to career shocks and provides an integrative definition and conceptualisation. We hope that this will ignite future research on an important but often overlooked topic.
Population connectivity of Ezo abalone on the northern Pacific coast of Japan in relation to the establishment of harvest refugia

Population connectivity among 7 fishery grounds of Ezo abalone Haliotis discus han- nai on the northern Miyagi coast (approximately 80 km) was investigated using hydrodynamic and particle-tracking models. The objectives were to: (1) clarify the larval dispersal processes, (2) quantify the dispersal distance of larvae and (3) estimate the population connectivity. To simulate larval dispersal, particles were released at the timings of spawning estimated from the shell lengths of newly settled abalone. The larval dispersal was simulated for 2 periods. The modeled hydrodynamics in the first period simulated stormy conditions because of the passage of a low- pressure system whereas that in the second period simulated relatively calm conditions. In the first period, the spawning appeared to be triggered by the low-pressure system, and the larval disper- sal was estimated to be generally greater than that in the second period. The mean dispersal dis- tances were less than 40 km in both periods. Model results indicate that abalone in the fishery grounds on the mid- and southern coast exhibit 2 distinct larval dispersal patterns. The number of connected sites was 3 to 7 and 2 to 4 in the stormy and relatively calm conditions, respectively. The calmer hydrodynamic conditions were favorable for self-replenishment. Self-recruitment was usu- ally greater than the connectivity with the other fishery grounds; however, poor self-recruitment occurred in some fishery grounds. This implies that the restocking and protection of local resources do not always lead to an increase in local recruitment, and it is necessary to investigate the larval dispersal processes from each larval source for successful management.
Length-Weight relationship and relative condition factor of Anabas testudineus (Bloch) of Deepar Beel (wetland) of Assam, India

The present study reports the length-weight relationship of male and female Anabas testudineus (Bloch) of Deepar Beel (wetland) of Assam. The fishes are separated into both male and female for calculation of length weight relationship and relative condition factor. The growth performance of length-weight relationship are found high since the correlation coefficient ‘r’ exhibits high degree of relationship with positive allometric correlation in both male and female Anabas testudineus. The Kn value of Male Anabas testudineus ranges between 0.79 and 1.42 with an average of 0.98±0.13 while in female it ranges between 0.71 and 1.29 with an average of 1.02±0.11. The relative condition factor in male is observed to increase from lighter to heavier fish. However, in female the relative condition factor initially declines from lighter to heavier fish and exhibits the lowest value at medium sized fish and thereafter steadily inclines to get the highest value in bigger fish having size range of ±13 cm TL.
Male-biased latitudinal cline of Jungle Crows on Sakhalin Island

Sakhalin Island, one of the largest islands in the Russian Federation, is isolated from the Eurasia continent by the Tatarsky Strait and from Japan’s Hokkaido Island by La Pérouse Strait. The island stretches in a meridional direction roughly 950 km and has maximum and minimum widths of 160 km and 26 km respectively. The Jungle Crow (Corvus macrorhynchos) inhabits the entirety of Sakhalin Island. No geographic barrier exists that would prevent crows from migrating between the southern and northern portions of the island. The entire island is in the oceanic climate zone and has a temperature seasonality that shows a clear gradation in the meridional direction, becoming progressively larger from south to north. The island thus has potential utility for addressing latitudinal variation in the Jungle Crow’s morphology. The author collected the crows serially from the south end of Sakhalin Island to the north end during June-July of 2007 breeding season. Two methods – the phenetic and metric approaches – were applied in the current skull-morphology study. Three phenetic traits, metric ten traits and body mass demonstrated neither clines nor gaps in latitudinal distribution for both sexes, with the exception of all five metric traits from the bill block in the male sample set. The male-biased cline, decreasing reversely from south to north, coincided with temperature seasonality; the cline in male bill size was found to be in accordance with Allen’s rule.
Is it smart to believe in God?: The relationship of religiosity with education and intelligence

The relationship of religiosity with education and intelligence was investigated with data from the World Values Survey covering a total of 345,743 respondents in 96 countries. The individual-level relationship of education with religious belief was slightly but significantly negative in the majority of countries, although its relationship with religious attendance was substantially less negative. At the country level, religious belief has independent negative relationships with intelligence and a history of communist rule, but not with educational exposure and logtransformed GDP. The results suggest that a weak negative relationship of religiosity with education is culturally amplified into far larger differences at the country level, and that the effect of education is mediated by cognitive skills. The results suggest that secularization during the 20 th
How Job Satisfaction Factors Affects Components of Organizational Commitment: Study on Employees of Star Hotels in Eritrea

This study focused on how job satisfaction factors affects components of organizational commitment among the basic employees of star hotels in Eritrea. Besides, the impact of control variables on the relationship between job satisfaction factors and components of organizational commitment were assessed. Job Satisfaction Survey (JSS) by Spector and Organizational Commitment Questionnaire (OCQ) by Mayer and Allen were used to measure the respondents’ job satisfaction and organizational commitment. Pearson Correlation analysis was done to identify the relationship between the independent variables and dependent variable. The results indicates that there is significant relationship between pay satisfaction, satisfaction with promotion, satisfaction with nature of work and satisfaction with communication in the organization and employees’ organizational commitment, in which each variables is significant at p=. 000. Nevertheless, satisfaction with supervision and co-workers found to be insignificant to contribute to basic employees’ commitment with p>0.05. With regard to the degree and direction of relationship, satisfaction with pay has strong and positive relationship, satisfaction with promotion, nature of work and communication possesses a moderate positive relationship with organizational commitment. To identify whether control variables have impact on the relationship b/n job satisfaction factors and components of organizational commitment, a hierarchical stepwise multiple regressions was examined. Though the correlation analysis illustrated that pay, promotion, nature of work and communication can contributes to the basic employees’ affective, continuance and normative commitment, but with the presence of the control variables the result appeared differently. On the presence of control variables, pay, promotion, supervision and communication can contributes to the employees’ affective commitment; pay and promotion can contributes to the employees’ continuance commitment and only pay can contributes to the employees’ normative commitment.

The FITS model: an improved Learning by Design approach

This paper presents a pretest-posttest design study that compares conceptual learning gains of 237 students, divided into two groups, exposed to a modified and remodified Learning by Design (LBD) task. LBD uses design contexts to learn skills and conceptual knowledge where research around the year 2000 showed high skill performances but disappointing conceptual learning gains. By a series of exploratory studies, previous to the study discussed in this paper, this issue was addressed, which resulted in modifications that were tested on a small scale. As a result the level of concept learning increased significantly. Analysis of the modified LBD group results in this paper confirms this improvement quantitatively by comparing results with available data on a traditional LBD approach (77 students). Further modifications, resulting in a remodified LBD approach, show an even further improvement through reduced fragmentation of the learning task and addressed science. Overall, the remodified approach (FITS model: Focus - Investigation - Technological design - Synergy) enriches technology education by stimulating an empirical and conceptual way of creating design solutions what is a catalyst for interdisciplinary teaching.
Dynamic Social Network Analysis for Infrastructure Transportation Systems

It is essential to build, maintain, and use our transportation systems in a manner that meets our current needs while addressing the social and economic needs of future generations. In today’s world, transportation congestion causes serious negative impacts to our societies. To this end, researchers have been utilizing various statistical methods to better study the flow of traffic into the road networks. However, these valuable studies cannot realize their true potential without solid in-depth understanding of the connectivity between the various traffic intersections. This paper bridges the gap between the engineering and social science domains. To this end, the authors propose a dynamic social network analysis framework to study the centrality of the existing road networks. This approach utilizes the field of network analysis where: (1) visualization and modeling techniques allow capturing the relationships, interactions, and attributes of and between network constituents, and (2) mathematical measurements facilitate analyzing quantitative relationships within the network. Connectivity and the importance of each intersection within the network will be understood using this method. The authors conducted social network analysis (SNA) using a two studies in Louisiana. Results indicate intersection SNA modeling aligns with current congestion studies and transportation planning decisions.
Management of Urinary Tract Infections: Problems and Possible Solutions

In clinically suspected urinary tract infections (UTIs), empirical antibiotic treatment is usu- ally started long before the laboratory results of urine culture and antibiogram are available. Although molecular diagnostic approaches are being applied to the diagnosis of many infections, UTIs are generally diagnosed by traditional culture methods. Patient care could greatly benefit from the development of a rapid, accurate, inexpensive test that could be done at patient’s bedside, allowing the practitioner to plan targeted, more effective therapy. Such a test would potentially reduce incorrect or unnecessary use of antibacterial drugs and reduce the emergence of bacterial resistance. In response to this pressing and unmet clinical need, several methods have been developed in the last few years. Among these, the new point-of-care test (POCT) for detecting UTIs named Micro Biological Survey (MBS) UTI CHECK holds promise, as it allows semi-quantitative determination of bacterial load in urine leading to a fast detection of UTIs and to evaluation of bacterial antibiotic susceptibility. This new technology operates through a colorimetric survey performed in low-cost, ready-to-use, disposable vials, in which 1 ml of urine is inoculated without any preliminary treatment and requiring neither specialized personnel nor a specialized equipment.
