Concise Review: A Comprehensive Analysis of Reported Adverse Events in Patients Receiving Unproven Stem Cell-Based Interventions
Authors: Bauer Gerhard , Elsallab Magdi , Abou-El-Enein Mohamed
Published: August 2018

The promise of stem cell (SC) therapies to restore functions of damaged tissues and organs brings enormous hope to patients, their families, loved ones, and caregivers. However, limits may exist for which indications SC therapies might be useful, efficacious, and safe. Applications of innovative therapies within regulatory boundaries and within the framework of controlled clinical trials are the norm in the scientific and medical community; such a system minimizes patient risk by setting a clear and acceptable safety and efficacy profile for new therapeutics before marketing authorization. This careful clinical validation approach often takes time, which patients suffering from terminal or debilitating diseases do not have. Not validated, unproven stem cell interventions (SCI) that promise a working treatment or cure for severe diseases have therefore found their way into the patient community, and providers of such treatments often take advantage of the public's willingness to pay large amounts of money for the misguided hope of a reliable recovery from their illnesses. We conducted a review of scientific publications, clinical case reports, and mass media publications to assess the reported cases and safety incidents associated with unproven SCI. The review also analyzes the main factors that were identified as contributing to the emergence and global rise of the “stem cell tourism” phenomenon.

ZnO/NiO thin films, each of thickness 100 nm, were deposited on Si(100) substrate by pulsed laser deposition method. The resulting heterojunction, ZnO/NiO/Si, was irradiated by 120 MeV Au9+ ions and characterized by grazing incidence X‐ray diffraction (GIXRD), Raman spectroscopy, and atomic force microscopy (AFM). The GIXRD confirmed the presence of both NiO and ZnO in the samples. Ion irradiation induced suppression of crystalline nature, and the recrystallization of the same occurred at the fluence of 1 × 1013 ions cm−2. The occurrence of most intense band at 302 cm−1 in Raman spectra corresponds to the symmetric stretching vibration of ZnO. The linear shift of stretching mode of ZnO with ion fluence could be associated with the effect of compressive stress in the material. AFM analysis of the films indicated that the rms roughness increased when the film is irradiated at a fluence of 1 × 1012 ions cm−2. Beyond this fluence, the value of roughness decreased up to fluence of 1 × 1013 ions cm−2 and increased thereafter. To see the effect of the stress of buffer layer on the surface layer, we calculated the stress for NiO layer with ion fluence form the lattice parameter. Comparing the stress of buffer layer with roughness of surface layer at the given fluence, we can say that the compressive stress in the buffer layer could possibly control the roughness of the surface layer.

Published: August 2018

Light emission during 5 keV Kr+ ion bombardment of Cu, Al, and CuAl alloys with different concentration is studied. The transient effect phenomenon has been investigated under two pressure conditions: one at base pressure (approximately 10−7 Pa) and the other with introduction of oxygen gas (approximately 10−4 Pa). The experimental oxygen sputtering yield was compared with simulation using the SRIM‐code program. Both of them were in fairly good agreement.
Gender Bias in Parental Attitude: An Experimental Approach
Authors: Begum Lutfunnahar , Grossman Philip J. , Islam Asadul
Published: August 2018

Parental bias toward children of a particular gender has been widely observed in many societies. Such bias could be due to pure gender preference or differences in earning opportunities and concern for old-age support. We conduct a high-stakes allocation task (subjects allocate the equivalent of one day’s wages between male and female school-aged students) in rural Bangladesh to examine parental attitudes toward male and female children. Parents, either jointly or individually, allocated freely or restricted endowments for the benefit of anonymous girls or boys at a nearby school. We examine whether there is any systematic bias among fathers and mothers and, if so, whether such bias differs when they make the decision individually or jointly. The results suggest (1) bias both for and against boys or girls but no systematic bias by either parent; and (2) no significant differences in individual and joint decisions.
RACIAL DIFFERENCES IN THE EFFECT OF MARRIAGEABLE MALES ON FEMALE FAMILY HEADSHIP
Authors: Craigie Terry-Ann , Myers Samuel L. , Darity William A.
Published: August 2018

Female family headship has strong implications for endemic poverty in the United States. Consequently, it is imperative to explore the chief factors that contribute to this problem. Departing from prior literature that places significant weight on welfare-incentive effects, our study highlights the role of male marriageability in explaining the prevalence of never-married female family headship for blacks and whites. Specifically, we examine racial differences in the effect of male marriageability on never-married female headship from 1980 to 2010. By exploiting data from IPUMS-USA (N= 4,958,722) and exogenous variation from state-level sentencing reforms, the study finds that the decline in the relative supply of marriageable males significantly increases the incidence of never-married female family headship for blacks but not for whites.
Meeting the Challenges of International Crises: The Experience of the Iranian Blood Transfusion Organization
Authors: Hosseini Divkolaye Nasim Sadat , Seighali Fariba , Pourfathollah Ali Akbar , Radfar Mitra , Burkle Frederick M.
Published: August 2018

Crises require a timely and well-prepared response by health services, especially those that are directly engaged with the lives of the patients such as blood services. The Iranian Blood Transfusion Organization as a single national authority of blood transfusion has left many crises behind. In this study, we examined the main international crises that the blood transfusion organization has faced during its 44-year history and objectively evaluated the methods for crisis risk reduction, both administrative and operational, all of which have led to fundamental advances in the organization. By proper planning and effective strategy setting, the Iranian Blood Transfusion Organization has managed to cope with international threats and in some cases has turned threats into opportunities to implement new, permanent administrative and operational strategies. It is not prudent for blood transfusion centers to develop their disaster risk reduction strategies on an individual-country basis in a world where global risk and crisis factors are rapidly increasing. Reduction of risk for blood transfusion centers must become a strategic priority nationally and globally. (Disaster Med Public Health Preparedness. 2019;13:410-413)
Perioperative antimicrobial prophylaxis and prevention of hepatobiliary surgical site infections
Authors: Stack Conor M. , Gold Howard S. , Wright Sharon B. , Baldini Linda M. , Snyder Graham M.
Published: August 2018

Objective

To characterize the microbiology of hepatobiliary surgical site infections (SSIs) and to explore the relationship between specific antimicrobial prophylaxis regimens and the development of SSIs.

Design

Retrospective matched case-control study comparing patient, procedure, and antimicrobial prophylaxis characteristics among patients undergoing a hepatobiliary surgical procedure with and without an SSI.

Setting

A tertiary referral acute-care facility.

Methods

Patients undergoing procedures defined as “BILI” (bile duct, liver, or pancreas surgery) using National Healthcare Safety Network (NHSN) definitions, excluding those undergoing concomitant liver transplantation, from January 2013 through June 2016 were included in the study population. The SSIs were identified through routine infection control surveillance using NHSN definitions. All patients who developed an SSI were considered cases. Controls were selected randomly matched 2:1 with cases based on fiscal quarter of the procedure. Logistic regression modeling was performed to explore variables associated with SSI, including antimicrobial prophylaxis received.

Results

Among 975 procedures, 80 (8.2%) resulted in an SSI. Most cases involved an organism nonsusceptible to standard prophylaxis regimens, including cefazolin (68.8%), cefazolin plus metronidazole (61.3%), and ampicillin-sulbactam (52.5%). In a multivariate model, antimicrobial coverage against Enterococcus spp (aOR, 0.58; 95% confidence interval [CI], 0.17–2.04; P=.40) and against Pseudomonas spp (aOR, 2.40; 95% CI, 0.56–10.29; P=.24) were not protective against the development of an SSI. The presence of a documented β-lactam allergy was significantly associated with the development of an SSI (aOR, 3.54; 95% CI, 1.36–9.19; P=.009).

Conclusions

Although SSIs at the study institution were associated with pathogens nonsusceptible to the most commonly used prophylaxis regimens, broader-spectrum coverage was not associated with a reduction in SSIs.

VARSOVIAN MODELS I
Authors: SARGSYAN GRIGOR , SCHINDLER RALF
Published: August 2018

Let Msw denote the least iterable inner model with a strong cardinal above a Woodin cardinal. By [11], Msw has a fully iterable core model, ${K^{{M_{{\rm{sw}}}}}}$, and Msw is thus the least iterable extender model which has an iterable core model with a Woodin cardinal. In V, ${K^{{M_{{\rm{sw}}}}}}$ is an iterate of Msw via its iteration strategy Σ.

We here show that Msw has a bedrock which arises from ${K^{{M_{{\rm{sw}}}}}}$ by telling ${K^{{M_{{\rm{sw}}}}}}$ a specific fragment ${\rm{\bar{\Sigma }}}$ of its own iteration strategy, which in turn is a tail of Σ. Hence Msw is a generic extension of $L[{K^{{M_{{\rm{sw}}}}}},{\rm{\bar{\Sigma }}}]$, but the latter model is not a generic extension of any inner model properly contained in it.

These results generalize to models of the form Ms (x) for a cone of reals x, where Ms (x) denotes the least iterable inner model with a strong cardinal containing x. In particular, the least iterable inner model with a strong cardinal above two (or seven, or boundedly many) Woodin cardinals has a 2-small core model K with a Woodin cardinal and its bedrock is again of the form $L[K,{\rm{\bar{\Sigma }}}]$.

Northeastern China is a region of high tick abundance, multiple tick-borne pathogens and likely human infections. The spectrum of diseases caused by tick-borne pathogens has not been objectively evaluated in this region for clinical management and for comparison with other regions globally where tick-transmitted diseases are common. Based on clinical symptoms, PCR, indirect immunofluorescent assay and (or) blood smear, we identified and described tick-borne diseases from patients with recent tick bite seen at Mudanjiang Forestry Central Hospital. From May 2010 to September 2011, 42% (75/180) of patients were diagnosed with a specific tick-borne disease, including Lyme borreliosis, tick-borne encephalitis, human granulocytic anaplasmosis, human babesiosis and spotted fever group rickettsiosis. When we compared clinical and laboratory features to identify factors that might discriminate tick-transmitted infections from those lacking that evidence, we revealed that erythema migrans and neurological manifestations were statistically significantly differently presented between those with and without documented aetiologies (P< 0.001,P= 0.003). Twelve patients (6.7%, 12/180) were co-infected with two tick-borne pathogens. We demonstrated the poor ability of clinicians to identify the specific tick-borne disease. In addition, it is necessary to develop specific laboratory assays for optimal diagnosis of tick-borne diseases.
The Oxford Handbook of Dance and Politics
Authors: Wilbur Sarah
Published: August 2018

At 656 pages wide and 31 authors deep, The Oxford Handbook of Dance and Politics collection contains a veritable who's who of US, UK, and EU dance scholarship. It also importantly documents the weight of the loss to the field of coeditor Randy Martin, whose materialist investigations of dance and politics influence the volume's contributions in powerful and explicit ways. Through the dedicated energies of Martin's fellow coeditors Rebekah Kowal and Gerald Siegmund, the volume updates an editorial burden assumed by earlier collections and field progenitors: interpreting dance's irreconcilable relationship to politics, a tension that the volume's contributors do not promise to reconcile. But what the text does, and with great urgency, is to revise and update long-standing debates on dance's politics of representation while also flagging hierarchical issues internal to dance research as areas for future investigation.

Making salt-reduced products more appealing to consumers: impact of front-of-pack messages on liking and table salt use over time
Authors: Zandstra Elizabeth H , Willems Astrid A , Lion René
Published: August 2018

Objective

The current study investigated the impact of different front-of-pack messages on liking, salt perception and table salt use of salt-reduced soups over repeated consumption.

Design

In a between-subjects design, participants consumed a chicken noodle soup five times over 3 weeks. Participants were assigned to one of five experimental conditions and were categorized into three ‘Interest in Salt Reduction’ groups based on their self-reported interest in salt reduction. They consumed a regular-salt soup or a 30 % salt-reduced soup, either with or without a front-of-pack message (nutritional, sensory or social based). Liking, salt perception and table salt use were measured at each consumption.

Setting

Central location test.

Subjects

British consumers (n 493) aged 24–65 years.

Results

The soups remained stable in liking over repeated consumption, with no significant differences between the experimental conditions. However, liking did differ among the different Interest in Salt Reduction groups: the ‘not aware, no action’ group liked salt-reduced soups with a nutritional message the most, whereas the ‘aware and action’ group liked salt-reduced soups with a social message the most. There was no change in the amount of table salt added as people got more familiar with the salt-reduced soups, suggesting a strong role for habit in table salt use.

Conclusions

It mattered whether consumers were thinking about reducing their salt intake or not: a communication message tailored to a country’s interest in reducing salt is recommended to motivate consumers to lower their salt intake.

Rediscovering the disc origin of the Milky Way bulge
Authors: Fragkoudi F. , Di Matteo P. , Haywood M. , Gómez A. , Khoperskov S. , Katz D. , Schultheis M. , Combes F. , Semelin B.
Published: August 2018

We explore morphological, kinematic and chemical trends of boxy/peanut (b/p) bulges of Milky Way (MW)-type galaxies, to better understand the formation history of the MW’s bulge. We show, using N-body simulations with both a kinematically cold and a kinematically hot disc, that colder populations develop a more prominent bar and X-shaped peanut as compared to their hotter counterpart. Colder discs also exhibit lower line-of-sight velocities (when viewed edge-on) at the edges of the b/p compared to hot discs, in agreement with what is seen for the MW bulge. Furthermore, we explore an N-body model which has three co-spatial discs with metallicities which correspond to the stellar populations of the inner Milky Way, where the α-enhanced thick disc populations are massive and centrally concentrated. The metallicity trends seen in observations of the Bulge can be reproduced in the model without the need of adding any additional components, which hints to the disc origin of the MW’s bulge.
Survey of Thermal Plasma Composition in Saturn's Magnetosphere Using Time‐of‐Flight Data From Cassini/CAPS

Published: August 2018

The Cassini spacecraft orbited Saturn from 2004 to 2017, and in 2006 it started exploring the deep magnetotail, reaching distances of about 68 RS (where RS is the equatorial radius of Saturn). Since Cassini covered a broad area of Saturn's magnetosphere, this raises the question of what is the typical and atypical plasma composition in different regions of Saturn's environment. In this paper, we present a survey of the bulk plasma composition using time‐of‐flight data from the Plasma Spectrometer/Ion Mass Spectrometer instrument on Cassini, from 2004 through 2012. This is the most comprehensive study ever made of relative abundances of thermal plasma at Saturn, maximizing the use of Cassini's orbital coverage in Saturn's magnetosphere during those years, and, therefore, the sensitivity to seasonal or natural variability of the system. We studied the ratio of counts between ions with E/q≃1.19–21,300 eV/q and mass per charge equal to 2 (either H
or He++) and ionized hydrogen ([(m/q = 2)]/[H+]), and a mixture of ions (H2O+, H3O+, OH+, and O+), known as the water group (W+) and ionized hydrogen ([W+]/[H+]). We present the data as a function of position in the magnetosphere, radial distance and local time, and distance from the planet and longitude with respect to the moons Enceladus, Dione, Rhea, and Titan. We found that the plasma composition in Saturn's magnetosphere presents significant local time asymmetries and variability.
Advancing Graph‐Based Algorithms for Predicting Flow and Transport in Fractured Rock

Published: August 2018

Discrete fracture network (DFN) models are a powerful alternative to continuum models for subsurface flow and transport simulations because they explicitly include fracture geometry and network topology, thereby allowing for better characterization of the latter's influence on flow and transport through fractured media. Recent advances in high performance computing have opened the door for flow and transport simulations in large explicit three‐dimensional DFN, but this increase in model fidelity and system size comes at a huge computational cost because of the large number of mesh elements required to represent thousands of fractures (with sizes that can range several orders of magnitude, from millimeter to kilometer). In most subsurface applications, fracture characteristics are only known statistically and numerous realizations are needed to bound uncertainty in flow and transport in the system, thereby exacerbating the computational burden. Graphs provide a simple and elegant way to characterize, query, and interrogate fracture network connectivity. We propose a DFN model reduction framework where various graph representations are used in conjunction with high‐fidelity DFN simulations to increase computational efficiency while retaining accuracy of key quantities of interest. The appropriate choice of a graph representation, namely, which attributes of the DFN are to be represented as nodes and which ones as edges connecting those nodes, depends on the relevant scientific questions. We demonstrate that the proposed DFN model reduction framework provides an efficient means for DFN modeling through both system reduction of the DFN using graph‐based properties and combining DFN and graph‐based flow and transport simulations.

Kinematics and Dynamics of the Pamir, Central Asia: Quantifying the Roles of Continental Subduction in Force Balance
Authors: Jay Cassidy N. , Flesch Lucy M. , Bendick Rebecca O.
Published: August 2018

An updated kinematic model constrained by GPS observations and fault slip rate information from the Central Asia Fault Database provides updated modeled slip rates for major faults in the Pamir. The kinematic model constrains thin sheet continuum mechanics models that distinguish the contributions of subducting continental lithosphere to force balance. Dynamic model sensitivity tests show that major features of the force balance results are insensitive to chosen lithospheric compensation style, integration depth, and inclusion of subducting low‐density continental lithosphere in the upper 100 km. Forward models incorporate deviatoric stresses associated with gravitational potential energy, velocity boundary conditions, and lateral strength variations. Differential strain rate fields, which represent residual forces not accounted for in the forward models, separate and quantify the deformation associated with the Pamir slab. The downward pull of foundering lithosphere augments compression along the Pamir Frontal Thrust System and shear along the eastern and western Pamir boundaries. North‐south extension in the residual differential strain rate field is spatially associated with Pamir gneiss domes and may be related to the interaction of the slab with the mantle. We do not find evidence for slab pull associated with a separate Hindu Kush slab.

Published: August 2018

The genus Methanosphaera is a well-recognized but poorly characterized member of the mammalian gut microbiome, and distinctive from Methanobrevibacter smithii for its ability to induce a pro-inflammatory response in humans. Here we have used a combination of culture- and metagenomics-based approaches to expand the representation and information for the genus, which has supported the examination of their phylogeny and physiological capacity. Novel isolates of the genus Methanosphaera were recovered from bovine rumen digesta and human stool, with the bovine isolate remarkable for its large genome size relative to other Methanosphaera isolates from monogastric hosts. To substantiate this observation, we then recovered seven high-quality Methanosphaera-affiliated population genomes from ruminant and human gut metagenomic datasets. Our analyses confirm a monophyletic origin of Methanosphaera spp. and that the colonization of monogastric and ruminant hosts favors representatives of the genus with different genome sizes, reflecting differences in the genome content needed to persist in these different habitats.

Published: August 2018

Mowat-Wilson syndrome (MWS) is characterized by severe intellectual disability, absent or impaired speech and microcephaly, with a gradual post-natal onset. The syndrome is often confused with other Angelman-like syndromes (ALS) during infancy, but in older children and adults, the characteristic facial gestalt of Mowat–Wilson syndrome allows it to be distinguished easily from ALS. We report two cases in which an exome-first approach of patients with MWS identified two novel deletions in the ZEB2 gene ranging from a 4 base deletion (case 1) to at least a 573 Kb deletion (case 2).

A series of compounds formerly identified by high-throughput screening was studied for their ability to serve as pharmacoperones for the vasopressin type 2 receptor (V2R) mutant L83Q, which is known to cause nephrogenic diabetes insipidus (NDI). Three compounds were particularly effective in rerouting the mutant receptor in a concentration-dependent manner, were neither agonists nor antagonists, and displayed low cellular toxicity. Compound 1 was most effective and can be used as a molecular probe for future studies of how small molecules may affect NDI caused by mutant V2R. These compounds, however, failed to rescue the V2R Y128S mutant, indicating that the compounds described may not work in the rescue of all known mutants of V2R. Taken collectively, the present studies have now identified a promising lead compound that could function as a pharmacoperone to correct the trafficking defect of the NDI-associated mutant V2R L83Q and thus has the therapeutic potential for the treatment of NDI.

The vicinity of traffic signals is one of the most special and critical areas in the whole road system. Considering that the driver can obtain traffic signals information through two approaches: vision and the vehicle‐to‐vehicle (V2X) communication equipment in the vehicle, this study proposes two vehicle cooperative driving models that apply to the vicinity of traffic signals: the intelligent driver model (IDM) in the vicinity of traffic signals (IDM‐VT) and IDM in the vicinity of traffic signals under V2X environment (IDM‐VT‐V2X). These two models are both based on the intelligent driver model. In accordance with different situations of vehicles in the vicinity of traffic signals, such as distance from the traffic lights, whether there was another vehicle in front and different states of traffic lights, the pertinent analysis was conducted, and the cooperative driving strategy that satisfied the complicated situations of vehicle was proposed. These two models were verified and compared in the simulation experiment. The results of simulation show that when comparing with the IDM‐VT, the IDM‐VT‐V2X can reduce the average travel time and the average stop delay time by 12.98 and 98.32%, respectively, and it can also reduce 22.53% fuel consumption.

Context. Studying molecular species in protoplanetary disks is very useful to characterize the properties of these objects, which are the site of planet formation.

Aims. We attempt to constrain the chemistry of S-bearing molecules in the cold parts of circumstellar disk of GG Tau A.

Methods. We searched for H2S, CS, SO, and SO2 in the dense disk around GG Tau A with the NOrthem Extended Millimeter Array (NOEMA) interferometer. We analyzed our data using the radiative transfer code DiskFit and the three-phase chemical model Nautilus.

Results. We detected H2S emission from the dense and cold ring orbiting around GG Tau A. This is the first detection of H2S in a protoplanetary disk. We also detected HCO+, H13CO+, and DCO+ in the disk. Upper limits for other molecules, CCS, SO2, SO, HC3N, and c-C3H2 are also obtained. The observed DCO+/HCO+ ratio is similar to those in other disks. The observed column densities, derived using our radiative transfer code DiskFit, are then compared with those from our chemical code Nautilus. The column densities are in reasonable agreement for DCO+, CS, CCS, and SO2. For H2S and SO, our predicted vertical integrated column densities are more than a factor of 10 higher than the measured values.

Conclusions. Our results reinforce the hypothesis that only a strong sulfur depletion may explain the low observed H2S column density in the disk. The H2S detection in GG Tau A is most likely linked to the much larger mass of this disk compared to that in other T Tauri systems.

Published: August 2018

Fulfill needs of Siamese gourami still rely on the catch from nature, so the population in nature has become decreased. The increase of Siamese gourami fish production from culture is still constrained by the survival rate and slow growth rate in the seed phase. The purpose of this research was to determine the effect of Siamese gourami stocking density on the application of optimum temperature and salinity to growth performance for optimization of production capacity. Application of optimum temperature and salinity refers to the results of previous research, i.e., temperature of 28 °C and salinity 3 ‰. Siamese gourami seed with length of 2.96 ± 0.42 cm and weight of 5.27 ± 0.10 g used in the research. The experimental design used completely randomized design with four treatments, i.e. 1 fish L-1, 2 fish L-1, 3 fish L-1 and 4 fish L-1. The results showed that there were an effect of different stocking density on absolute growth weight and length, survival rate, specific growth rate and productivity. This is shown in the C treatment which growth was 4.95 ± 0.037 g, length 3.51 ± 0.01 cm, survival rate 93.47%, specific growth rate 1.22% and fish productivity of 625.76 g.

Bauxite production and exploration give negative impact environmental modification and increasing concern pollution of heavy metals. One of an alternative to reduce the negative impact of bauxite post-mining production is by re-utilizing the abandoned bauxite land and necessary exploratory study to obtain the current environmental conditions primarily related to heavy metals in bauxite mining area. Soil and water quality samples from 5 (five) sites based on post-mining activities were used to determine concentration heavy metals of As, Cd, Pb, Zn, Cr, Cu from different soil level. They were also collected for grain size analysis including those of sand and mud percentages along with the mean, and sorting analysis. The mean grain size post-mining bauxite ranged between very fine sand to medium sand and had heterogeneous texture. The coarse grain size percentage increased towards the bottom of the soil. Total heavy metal contents for post-mining bauxite soils are 0,081 ppm, 0,245 to 0,471 ppm and 0,007 ppm for As, Pb and Cd respectively. Heavy metals for Cd, uniformly at every depth from soil level. On the other hand, Pb showed significance pattern, it was indicated every depth from soil level, the concentration of Pb was different.

Giant clam is one of the most common types of bivalves found in coral ecosystem. Geographically, these clams have limited distribution in the Indo-Pacific tropics, from the Red Sea to the Pacific Islands of Tuamotu. Ecologically, the clam acts as bio-filtration and natural bio-deposition. The presence of clams becomes a marker that the waters are still good and the absence of harmful pollutants. The population of this clam in Indonesian waters continues to decline. Anambas archipelago are known for its rich diversity of marine life. Since the establishment of this area became NACA as an ATP in 2014, marine tourism activities grew rapidly. Therefore it is necessary to do this research which aims to know the diversity of species and abundance of clams in the waters of Anambas Islands. Field survey was conducted in August 2015 by using Belt Transect method. The research results found 6 species with D1 value is 0.593. The overall abundance is 0.144 indv.m-2. Tridacna crocea has the highest abundance and relative abundance of the highest species of the other species of 60.54%. Meanwhile, the smallest relative abundance is Tridacna gigas which is only 2.36%.

The water is an imperfect acoustic medium, acoustic energy can lost due to absorption and scattering thus resulting in transmission loss. The value of transmission loss in water is an important thing to know, for example in the application of active acoustic. This study aim is to determine the value of transmission loss in Tanjung Intan’s cruise line, Cilacap. The acquisition of vessel's sound data was obtained by hydrophone and vessel data (distance) by CCTV. Both sound data and vessel data were connected to personal computer to record the audio and visual signal synchronously for three consecutive days. Results showed that vessel characteristics such as intensity, frequency and interval duration have a value of 43.35 (dB), 6613.54 (Hz) and 216.15 (ms) respectively. While the value of water absorption coefficient has a range of 500-900 dB/km, the estimated transmission loss value was between 5-11 dB/km.
