THE EFFECT OF STOCK DENSITY OF GOLDEN-MOUTH TURBAN (Turbo chysostomus, L.) ON THEIR SURVIVAL AND GROWTH UNDER AIR WATER LIFT SYSTEM
Authors: Hamzah M.S.
Published: October 2017

Golden-mouth turban (Turbo chrysostumus, L.) belongs to the phylum of molluscs that inhabits coral reef ecosystem in group. Golden-mouth turban normally uses algae for their food. Study on survival and growth of the juvenile golden-mouth turban focussing on different density under air water lift sys-tem is still limited. This study was conducted on 7 January – 6 May,  2015, in a laboratory to observe the effect of different density on the survival and growth of golden-mouth turban under air water lift system. Based on the analyses of variance (ANOVA), there was no significant different (P>0.05) on mortality rate for different stock density treatment (5 ind., 10 ind., 15 ind., and 20 ind. each in 10 liter water volume). However, based on growth rate, the density of 5 individuals produced the highest monthly growth rate of 1.88 mm/month of shell height, 1.18 mm/month of mouth opening, and 1.1 gr/month of wet weight with the highest daily mean food absorption of 91.55 %. For all treatment, the correlation of shell height and wet body weight exhibited a similar growth pattrern i.e., allometry minor (b<3).

Published: October 2017

A study on Echinoderms community structure in marine national parks of Wakatobi, Southeast Sulawesi was conducted in six locations, i.e., Waha Beach, Coastal Sombo, Beach Houses, Beach Kapota, Banakawa beach, and Umala beach in October 2013. All of the six parks were located the Wakatobi territorial waters with coordinates of 5°06'25" S and 123°124'10 E. The results showed of 18 species of echinoderms representing six different types of Asteroidea, two types of Ophiuroidea, six types of Echinoidea, and four types of Holothuroidea. Group of starfish or Asteroidea was the most prominent on seagrass area. Based on the six transects sites, it turned out that the group of starfish (Asteridea) occupied a relatively high level of species richness. From the quantitative analysis values, we obtained diversity index (H) of 1.105 in Sombu, the highest evenness index (J) of 0.989 was found in Umala, and the highest species richness index values (D) of 0.132 was obtained in kapota. It seemed that all echinoderm groups were generally like seagrass microhabitat (12 types). While, sand and dead coral habitats were only occupied by 8 (eight) echinoderm groups.

Authors: Nababan Bisman
Published: October 2017

Variability of sea surface temperature (SST) and the concentration of chlorophyll-a (Chla) in Jakarta Bay and its surrounding waters were analyzed based on the time series data of monthly mean SST and Chla estimated by NOAA AVHRR, SeaWiFS, and MODIS satellites for 17 years (1997 to 2014). Generally, the monthly mean SST values fluctuated seasonally with the semi-annual pattern with the maximum value occurred in the second transitional season (Oct-Nov) and relatively high in the first transitional season (Mar). In contrast, the minimum of monthly mean SST values was found during the east season (Jul) and relatively low during the west season (Des-Jan). SST variabilities were generally associated with the sun position, sea water circulation, and rainfall. Based on MODIS data, the minimum-maximum of monthly mean SST ranged of 28.39°C-32.58°C. Seasonal fluctuations with the semi-annual pattern also occurred in the monthly mean Chla values with the maximum value occurred during the west season (Des-Jan) and relatively high values occurred during the east season (Jun). In contrast, the minimum of the monthly mean Chla was found during the second transition season (Sep-Oct) and relatively low during the first transitional season (March-Apr). The minimum-maximum of monthly mean Chla ranged of 0.09 mg/m3-2.50 mg/m3. Chla fluctuations were generally associated with the variabilities of rainfall, river water discharge, and sea water circulation of the Java Sea. Anomalous climatic factors such as El Nino Southern Oscillation (ENSO) and La Nina produced a significant impact on the SST and Chla interannual variability. Generally, the ENSO phenomenon lo-wers the value SST and Chla, while La Nina events tended to increase Chla values.

A study on the effect of feeding frequency on coral trout culture Plectropomus leopardus was conducted in floating net cages. The aim of this study was to determine an optimum feeding frequency for better growth rate and feed conversion ratio. The experiment was divided into two stages, i.e.; using fish with a range of body weight of 24 to 100 g (1st stage), and fish with a range of 100 to150 g (2nd stage). The first stage, consisted of four treatments of feeding frequencies, i.e. four times a day (4/1), three times a day (3/1), twice a day (2/1), and once a day (1/1). For the second stage experiment, the treatments applied were, three times a day (3/1), twice a day (2/1), once a day (1/1), and once in two days (1/2). Each treatment was in triplicate. At each feeding time, experimental fish were fed with dry pellets to apparent satiation. Both first and second experimental stages showed that the treatments of twice a day (2/1) feeding frequency attained significantly higher growth rates and lower feed conversion ratios than other treatments (P<0.05). Survival rate at the first stage (4/1), three times a day (3/1), twice a day (2/1), higher than (1/1) (P<0.05). But in the second stage the survival rate is not significant. The most optimum feeding frequencies for this species is 2/1 for the fish of 24 to 150 g BW.

Published: October 2017

Indonesia is an archipelagic country with many locations suit for aquaculture. Grouper hatcheries are still concentrated in a few locations. Therefore, appropriate technology to transport live grouper seed is needed to ensure the survival and health of the seed. This study aimed to determine the duration of fasting before transportation and the optimum density of grouper seed during transportation. Transportation was conducted in closed system, transported using a car, for 24 hours. Grouper seed used for the experiment was cantik hybrid grouper, a cross-breed between female tiger grouper (Epinephelus fuscoguttatus) and male marbled grouper (Epinephelus microdon) with an average of size 7.0±0.32 cm. There were 2 experiments in this study. Experiment 1 was different durations of fasting before transprotation: A. 12 hours, B. 24 hours, C. 36 hours and D. 48 hours with the density of 150 seeds/boxes. The result of the first experiment was used to determine the experimental design of experiment 2, which consisted of 4 different densities per boxes: A. 125 seeds, B. 150 seeds, C. 175 seeds and D. 200 seeds. Both of the experiments were conducted in triplicates. The seeds were packed in plastic bags with a thickness 0.08 mm, length 120 cm x width 53 cm, filled with 10 liters of sea water. The results showed that the duration of fasting from 36 to 48 hours had the highest survival rate. Polinomial relation y = -0.0439x2 + 3.7696x + 17.075 with the value of R² = 0.966 illustrated that the optimum duration of fasting was 44 hours. There was a significant difference in densities of seeds during transportation (P<0.05), where the higher density lead to the lower survival rate. The density of 125 seeds/boxes resulted in the highest survival rate, 99.0 ± 1.0%.

Published: October 2017

Majakerta estuary and its surrounding waters have a high potential fishery resource which is commonly utilized by the community around the area. Fluctuation of physical and chemical parameters of the waters and fishery activities around the estuary can influence the existence of  zooplankton. This study was conducted from December 2014 to May 2015. Samples of the zooplankton were collected monthly at four stations (consisted of sea, river and estuary areas). Based on the study, zooplankton in the  Majakerta estuary and its surrounding waters consisted of six classes; i.e. Protozoa (11 genera), Crustaceae (4 genera, 1 nauplius stadia), and Rotifera (4 genera). A higher abundance was found at the sea (29025 ind./m3), while a lower  abundance was at the river and estuary (7147 ind./m3 dan 7582 ind./m3).  Based on the zooplankton diversity index, it can be inferred that the value was relatively low. There were two habitat groups, namely Station Group 1 (Station 1 and  2; river and estuary) and Station Group 2 (Station  3 and 4; sea) with influencing parameters such as  transparency, pH, and salinity.

Published: October 2017

Mangrove restoration is really needed for restoring its ecosystem functions, so that it could be able to support fisheries activity and to protect coastal by extreme weather. In addition, mangrove is able to accumulate sediment that important in protecting the coastal area from sea level rise. Therefore,  the aim of this study is to investigate sediment accumulation rate in mangrove area during post restoration. Sampling location were divided into three different stations based on estimated restoration ages, such as ≥ 15  years old (Station 1), 4 - 10 years old (Station 2) and 2 - 8 years old (Station 3). Sediment cores were carried out by inserting 7.6 cm diameter and 100 cm length of polyvinyl chloride pipes. Sedimentation rate is measured by using Pb-210 radionuclide analysis. The results show that the sediment accumulation rate in the last 20th years from all station ranges from 0.17 to 0.42 g/cm2/year. The highest accumulation rate is found at oldest year old station while the lowest accumulation rate is found at younger year old station of mangrove restoration area. Restoration process is clearly able to recover the mangrove’s role in trapping sediment in coastal region.

The Visual Construction of the Myth of the Albanian National Leader
Authors: Vuka Denis
Published: October 2017

This article examines the visual construction of the myth of the Albanian
national leader in history textbooks. By applying visual social semiotics, it explores
the function and usefulness of this myth during the critical years of Albania’s
self-isolation from 1978 to 1990. Depicted in recurring episodes that were decisive
for the existence of the national community, a capable leader emerges as its savior.
His figure is perceived as a symbol of unity and as the only actor able to pave the
way toward a bright future. This article argues that this myth served to legitimize
power and secure social cohesion.

Tree Automata Constructions from Regular Expressions: a Comparative Study
Authors: Mignot Ludovic , Sebti Nadia Ouali , Ziadi Djelloul
Published: October 2017

There exist several methods of computing an automaton recognizing the language denoted by a given regular expression: In the case of words, the position automaton 𝒫 due to Glushkov, the c-continuation automaton 𝒞 due to Champarnaud and Ziadi, the follow automaton ℱ due to Ilie and Yu and the equation automaton ɛ due to Antimirov. It has been shown that 𝒫 and 𝒞 are isomorphic and that ɛ (resp. ℱ) is a quotient of 𝒞 (resp. of 𝒫).

In this paper, we define from a given regular tree expression the position tree automaton 𝒫 and the follow tree automaton ℱ. Using the definition of the equation tree automaton ɛ of Kuske and Meinecke and our previously defined c-continuation tree automaton 𝒞, we show that the previous morphic relations are still valid on tree expressions.

BACKGROUND:

Individuals with exceptional longevity and their offspring manifest a lower prevalence of age-related diseases than families without longevity. However, the contribution of dietary habits to protection from disease has not been systematically assessed in families with exceptional longevity.

OBJECTIVE:

The aim of this study is to compare dietary patterns between individuals with parental longevity and individals without parental longevity.

METHODS:

Dietary intake was evaluated using the Block Brief Food Frequency Questionnaire in 234 community dwelling Ashkenazi Jewish adults aged 65 years and older who were participants of the LonGenity study, which enrolls the offspring of parents with exceptional longevity (OPEL) and offspring of parents with usual survival (OPUS).

RESULTS:

OPEL constituted 38% of the subjects. The two groups had similar daily intake of total calories (1119 vs. 1218 kcal, p = 0.83), grams of cholesterol (141 g vs. 143 g, p = 0.19), and grams of sodium (1324 g vs.1475 g, p = 0.45), in OPEL vs. OPUS respectively. There were also no significant differences in the intake of other macronutrients, micronutrients, nutritional supplements and consumption of various food groups between OPEL and OPUS after adjustment for age and sex.

DISCUSSION:

A healthy diet is associated with a lower risk of several chronic diseases. Our study revealed that dietary intake did not differ between OPEL and OPUS; thus, pointing to the role of longevity genes in protecting from disease among individuals with familial longevity.

CONCLUSION:

The offspring of long-lived parents do not differ in their dietary patterns compared to individuals without parental longevity.
The Body's Testimony: Dramatic Witness in the Eichmann Trial
Authors: Caruth Cathy
Published: October 2017

This article takes as its focus the question, raised by Shoshana Felman and Dori Laub in their 1995 book Testimony: Crises of Witnessing in Literature, Psychoanalysis and History, of what it means for an event to be constituted by the collapse of its witness. The discussion centres on a reading of the moment Yehiel Dinoor, a writer also known as K-Zetnik and one of the few eyewitnesses at the 1961 Eichmann trial in Jerusalem, falls out of the stand and into a coma while attempting to provide his testimony. By rethinking this historical trauma as a ‘collapse of witnessing’, I suggest Felman and Laub shift the focus from a purely cognitive or epistemological question — a problem of knowing and not-knowing — to a question of communicating to others: a problem of address. It is the circumstance of having ‘no one to whom one could say Thou’, as Laub puts it (Testimony, 82), that constitutes the Holocaust, for the victims, as what the authors call an ‘event without a witness’.
The Function and Field of Scansion in Jacques Lacan's Poetics of Speech
Authors: Alfandary Isabelle
Published: October 2017

This article seeks to assess the meaning and scope of one of Lacan's most famous and decried notion: scansion. Scansion is a notion of prosody which undoubtedly was not chosen at random by Lacan. Scanning, which proved central to his conception of the analytic cure and handling of the treatment, turns out to be a gesture of a very particular kind: through an action which involves minimal intervention is revealed a double entendre, the content of the unconscious fantasy. The clinical function of scansion is hence to accentuate a ‘part’ of the subject's discourse to make it resonate, to isolate a signifier, to make it audible through its material and phonemic plasticity in its irreducible ambiguity. As the article tries to demonstrate, scansion is for Lacan of Freudian descent: clinically stemming and theoretically deduced from the principle of the determinism of the unconscious, it relies on the ‘weft’ of the dream's written fabric as evinced by The Interpretation of Dreams.
Strategies Using Bio-Layer Interferometry Biosensor Technology for Vaccine Research and Development
Authors: Petersen Rejane
Published: October 2017

Bio-layer interferometry (BLI) real-time, label-free technology has greatly contributed to advances in vaccine research and development. BLI Octet platforms offer high-throughput, ease of use, reliability, and high precision analysis when compared with common labeling techniques. Many different strategies have been used to immobilize the pathogen or host molecules on BLI biosensors for real-time kinetics and affinity analysis, quantification, or high-throughput titer. These strategies can be used in multiple applications and shed light onto the structural and functional aspects molecules play during pathogen-host interactions. They also provide crucial information on how to achieve protection. This review summarizes some key BLI strategies used in human vaccine research and development.

The Use of Size Exclusion Chromatography to Monitor Protein Self-Assembly
Authors: Adawy Alaa , Groves Matthew
Published: October 2017

High resolution size exclusion chromatography (SEC) coupled with static light scattering (SLS) analyses were conducted to study the effect of the mobile phase ionic strength and protein concentration on the output of SEC experiments. The results highlight the effect of small changes in the mobile phase composition on the estimation of molar masses estimated from retention time-based calibration curve compared with those obtained from SLS analysis. By comparing the SLS data with the SEC chromatograms, we show that SEC can provide helpful information on the protein aggregation state as macromolecules approach known precipitation points in their phase diagrams. This suggests the potential use of SEC as an easily accessible lab-based scanning methodology to monitor protein self-assembly prior to nucleation and crystallization. Implications for the use of SEC to study protein phase diagrams are discussed.

Published: October 2017

4,5,6,7-Tetrabromo-1H-benzotriazole (TBBT) is still considered a reference inhibitor of casein kinase II (CK2), a valuable target for anticancer therapy, even though the poor solubility in water of this active pharmaceutical ingredient (API) has prevented its implementation in therapy. We decided to explore the interactions preferentially formed by TBBT in crystalline solids in order to obtain information helpful for the development of new TBBT cocrystals possibly endowed with improved bioavailability. In this paper, we describe the synthesis and the structural characterization of the TBBT methanol solvate and of the TBBT salt with N,N,N’,N’-tetramethylethylenediamine. It is shown that TBBT can give rise to several competing interactions. This API is clearly a good halogen bond (XB) donor, with bromine atoms adjacent to the triazole ring possibly better donors than the two others. TBBT is also a good hydrogen bond (HB) donor, with the triazole hydrogen forming an HB with the acceptor or being transferred to it. Interestingly, one of the triazole nitrogens was proven to be able to work as a hydrogen bond acceptor.

Heart rate variability (HRV) analysis is a non-invasive tool for assessing cardiac health. Entropy measures quantify the chaotic properties of HRV, but they are sensitive to the choice of their required parameters. Previous studies therefore have performed parameter optimization, targeting solely their particular patient cohort. In contrast, this work aimed to challenge entropy measures with recently published parameter sets, without time-consuming optimization, for risk prediction in end-stage renal disease patients. Approximate entropy, sample entropy, fuzzy entropy, fuzzy measure entropy, and corrected approximate entropy were examined. In total, 265 hemodialysis patients from the ISAR (rISk strAtification in end-stage Renal disease) study were analyzed. Throughout a median follow-up time of 43 months, 70 patients died. Fuzzy entropy and corrected approximate entropy (CApEn) provided significant hazard ratios, which remained significant after adjustment for clinical risk factors from literature if an entropy maximizing threshold parameter was chosen. Revealing results were seen in the subgroup of patients with heart disease (HD) when setting the radius to a multiple of the data’s standard deviation ( r = 0.2 · σ ); all entropies, except CApEn, predicted mortality significantly and remained significant after adjustment. Therefore, these two parameter settings seem to reflect different cardiac properties. This work shows the potential of entropy measures for cardiovascular risk stratification in cohorts the parameters were not optimized for, and it provides additional insights into the parameter choice.
Influence of Trust on Biomass Supply Decision-Making in China
Authors: Wang Lingling , Watanabe Tsunemi
Published: October 2017

Given the abundant straw resources in Northeast China and the huge external costs associated with fossil fuels, straw-based biomass power plants have emerged as a popular alternative to coal-fired power plants. The sustainability of these green alternatives depends on straw supply from farmers, yet little is known about their perceptions regarding such supply because of a lack of cooperation in the supply chain. To better understand farmers’ opinions on supplying straw, this study examined their trust in middlemen, perceptions regarding risk in straw supply, the possibility of reducing transaction costs, and their willingness to supply straw. Data were collected from 275 farmers in the national bioenergy industry area in Wangkui County, Northeast China. We investigated the theoretical and empirical connections between trust and risk perception, trust and the possibility of reducing transaction costs, and trust and willingness to supply straw. The results indicated that education, income, and trust factors explained farmers’ risk perceptions, the possibility that they will reduce transaction costs, and their willingness to supply straw. On the basis of the analysis, a model of the influence of trust on straw supply was established. The overall findings indicated that biomass power plants and middlemen must build trusting relationships with farmers to ensure sustainable biomass supply.
5-Fluorouracil Treatment Alters the Efficiency of Translational Recoding

Published: October 2017

5-fluorouracil (5-FU) is a chemotherapeutic agent that has been extensively studied since its initial development in the 1950s. It has been suggested that the mechanism of action of 5-FU involves both DNA- and RNA-directed processes, but this has remained controversial. In this study, using a series of in vivo reporter constructs capable of measuring translational recoding, we demonstrate that cells exposed to 5-FU display a reduced capacity to engage in a variety of translational recoding events, including +1 programmed frameshifting (PRF) and −1 PRF. In addition, 5-FU-treated cells are much less accurate at stop codon recognition, resulting in a significant increase in stop codon-readthrough. Remarkably, while the efficiency of cap-dependent translation appears to be unaffected by 5-FU, 5-FU-treated cells display a decreased ability to initiate cap-independent translation. We further show that knockdown of thymidylate synthase, an enzyme believed to be at the center of 5-FU-induced DNA damage, has no effect on the observed alterations in translational recoding. On the other hand, ribosomal RNA (rRNA) pseudouridylation, which plays an important role in translational recoding, is significantly inhibited. Taken together, our results suggest that the observed effect of 5-FU on recoding is an RNA-directed effect. Our results are the first to show definitely and quantitatively that translational recoding is affected by exposure to 5-FU. Thus, it is possible that a substantial portion of 5-FU cytotoxicity might possibly be the result of alterations in translational recoding efficiency.
Self-Determination in Health Research: An Alaska Native Example of Tribal Ownership and Research Regulation
Authors: Hiratsuka Vanessa , Beans Julie , Robinson Renee , Shaw Jennifer , Sylvester Ileen , Dillard Denise
Published: October 2017

Alaska Native (AN) and American Indian (AI) people are underrepresented in health research, yet many decline to participate in studies due to past researcher misconduct. Southcentral Foundation (SCF), an Alaska Native-owned and operated health care organization, is transforming the relationship between researchers and the tribal community by making trust and accountability required features of health research in AN/AI communities. In 1998, SCF assumed ownership from the federal government of health services for AN/AI people in south central Alaska and transformed the health system into a relationship-based model of care. This change reimagines how researchers interact with tribal communities and established community oversight of all health research conducted with AN/AI people in the region. We describe the SCF research review process, which requires tribal approval of the research concept, full proposal, and dissemination products, as well as local institutional review board approval, and a researcher-signed contract. This review evaluates research through the lens of tribal principles, practices, and priorities. The SCF example provides a framework for other tribes and organizations seeking to reshape the future of health research in AN/AI communities.

We aimed to prospectively assess changes in chronic stress among young adults transitioning from high school to university or working life. A population-based cohort in Munich and Dresden (Germany) was followed from age 16–18 (2002–2003) to age 20–23 (2007–2009) (n = 1688). Using the Trier Inventory for the Assessment of Chronic Stress, two dimensions of stress at university or work were assessed: work overload and work discontent. In the multiple ordinal generalized estimating equations, socio-demographics, stress outside the workplace, and job history were additionally considered. At follow-up, 52% of the population were university students. Work overload increased statistically significantly from first to second follow-up, while work discontent remained constant at the population level. Students, compared to employees, reported a larger increase in work overload (adjusted odds ratio (OR): 1.33; 95% confidence interval (95% CI): 1.07, 1.67), while work discontent did not differ between the groups. In conclusion, work overload increases when young adults transition from school to university/job life, with university students experiencing the largest increase.
