Análisis de la nueva regulación del contrato menor en la Ley 9/2017, de 8 de noviembre, de Contratos del Sector Público
Authors: Carrodeguas Méndez Roberto
Published: October 2018

En el Boletín Oficial de Estado número 272, del 9 de noviembre de 2017, se publicó la  Ley de Contratos del Sector Público, entrando en vigor el pasado día 9 de marzo. Desde un primer momento, la configuración del contrato menor en la nueva Ley ha despertado un gran interés y preocupación, no solo entre los operadores jurídicos, sino también entre las propias empresas y profesionales que operan en el mercado. A pesar su corta vida, muchos son los interrogantes y dudas que ha generado el nuevo texto legal, proliferando opiniones doctrinales e informes de órganos consultivos en la materia con distinto criterio interpretativo, lo que ha provocado un elevado grado de inseguridad jurídica en el momento de aplicar la norma. Este trabajo pretende efectuar un estudio detallado de la figura del contrato menor y de su actual regulación normativa, analizando, desde un punto de vista práctico, las consecuencias que puede tener la nueva regulación en el ámbito de la Administración Pública. Por último, se exponen una serie de argumentos  en defensa del contrato menor que conducen a la conclusión de que una correcta utilización del mismo puede resultar de gran utilidad en el ámbito de la contratación pública local.
Las competencias exclusivas del Estado ex artículo 149.1.18ª de la Constitución y la disciplina de la producción normativa
Authors: Díaz González Gustavo Manuel
Published: October 2018

La Sentencia del Tribunal Constitucional 55/2018, de 24 de mayo, ha estimado parcialmente el recurso de inconstitucionalidad interpuesto por el Gobierno de Cataluña frente a diversos preceptos de la Ley 39/2015, de 1 de octubre, del Procedimiento Administrativo Común de las Administraciones Públicas. El pronunciamiento afecta a previsiones legales sustancialmente relacionadas con la disciplina de producción normativa y con la Administración electrónica. En el presente trabajo se estudia críticamente la doctrina afirmada en relación con el primero de los aspectos aludidos. Las dificultades a las que se ha debido enfrentar el juez de las leyes para la resolución del recurso de inconstitucionalidad en este punto, debidas fundamentalmente a la falta casi total de jurisprudencia previa en la materia, no le han impedido dictar una Sentencia que en líneas generales se encuentra, en nuestra opinión, correctamente fundamentada, si bien resulta posible identificar en ella algunos extremos en los que se echa en falta una mayor profundidad en el análisis.
QUALIDADE DE VIDA RELACIONADA À SAÚDE DE PACIENTES COM CÂNCER DE PRÓSTATA EM TRATAMENTO DE RADIOTERAPIA: REVISÃO INTEGRATIVA DE LITERATURA
Authors: Quijada Patricia Daniela dos Santos , Fernandes Paolla Algarte , De Oliveira Santos Branca Maria
Published: October 2018

O presente estudo objetiva analisar as publicações científicas de alto impacto que avaliaram a qualidade de vida relacionada à saúde de pacientes com câncer de próstata em tratamento radioterápico. Para tanto, ancora-se num estudo exploratório, de revisão integrativa da literatura, utilizando as bases de dados PubMed, Web of Science, Scopus e Lilacs, com os descritores: Quality of life, Prostatic neoplasms e Radiotherapy, usando o operador booleano AND. Do total de 1418 artigos localizados, foram excluídos 1403 após o uso dos filtros adotados como critérios de inclusão e exclusão, de acordo com cada base de dados, e leitura dos respectivos resumos, resultando em 15 artigos. Os resultados evidenciaram que o tratamento de radioterapia causa impacto na qualidade de vida relacionada à saúde dos pacientes, com manifestações de sinais e sintomas de intensidade variada, principalmente nas funções urinária, sexual e intestinal. Mesmo havendo declínio na qualidade de vida relacionada à saúde durante o tratamento, os efeitos negativos foram limitados e temporários, podendo melhorar com o passar do tempo. Ainda que os estudos tenham sido realizados em momentos e países diferentes, com amostras, modalidades de radiação e instrumentos distintos, os resultados contribuíram para o planejamento, a execução e avaliação do tratamento radioterápico no cotidiano dos serviços oncológicos, considerando a realidade de cada um. Recomenda-se a realização de novas pesquisas de modo a possibilitar a identificação dos efeitos dos diferentes tipos de radiação e suas consequências na vida dos pacientes, com vistas à escolha de medidas terapêuticas menos impactantes.

A não adesão dos homens aos serviços de saúde é um desafio para a enfermagem. Torna-se necessário vencer a resistência masculina ao cuidado preventivo consigo mesmo e incentivar hábitos e costumes de cuidado contínuo entre esta população antes de chegar ao nível terciário de atenção, bem com conhecer como os enfermeiros desenvolvem a Política Nacional de Atenção a Saúde do Homem. Materiais e método: Trata-se de uma pesquisa descritiva exploratória com abordagem qualitativa, desenvolvida com nove enfermeiros que trabalham na atenção primária. A coleta de dados ocorreu entre abril a julho de 2015, por meio de entrevista semiestruturada gravada. O número de participantes foi determinado pelo critério de saturação dos dados e os discursos foram analisados por meio da técnica de análise de conteúdo de Bardin. De acordo com os discursos foi possível a elaboração de três categorias: a capacitação e o conhecimento dos enfermeiros em relação à PNAISH; saúde do Homem na formação do enfermeiro e a demanda do atendimento à saúde do homem e ações desenvolvidas no município. A análise do modo como os enfermeiros desenvolvem a política permitiu afirmar que ainda há necessidade de investir em capacitação para os profissionais de enfermagem que trabalham nas unidades de saúde, possibilitando assim a realização de ações voltadas para população masculina. Verificou-se a necessidade de promover mudanças na forma de atender esta população, buscando capacitar os profissionais para que ampliem o olhar do processo de adoecimento da população masculina e possam auxiliar na promoção de ações e desenvolvimento de estratégias que atraiam os homens para as unidades.

O monitoramento do processo de trabalho da equipe de saúde pelo gestor local é uma estratégia para a democratização das ideias e ações, objetivando a transformação do modelo assistencial hegemônico, pois perpassa a função administrativa e integra o gerenciamento por meio do estímulo à liderança do enfermeiro. Buscou-se analisar as atividades gerenciais do enfermeiro no monitoramento das visitas domiciliares dos agentes comunitários de saúde. Trata-se de um estudo qualitativo, realizado com 14 enfermeiros atuantes na Estratégia Saúde da Família de município de médio porte de Mato Grosso, cuja coleta de dados deu-se em maio de 2017, sendo esta composta por entrevista individual e preenchimento de ficha de coleta de dados contendo questões semiestruturadas, que foram analisadas por meio da técnica de análise de conteúdo. Evidenciou-se a caracterização positiva do curso pelos enfermeiros, os quais relataram seu impacto na rotina da Atenção Básica. Os agentes mostraram-se mais comprometidos e compreensivos em relação aos benefícios de sua atuação e supervisão do enfermeiro, que desempenha o acompanhamento em visitas, verificação de registros, sistemas eletrônicos e reuniões mensais com a equipe. Foram apontados ainda alguns desafios a serem superados, como a sobrecarga de trabalho, burocratização dos serviços e falta de suporte dos gestores e instrumento norteador. Pode-se concluir que as atividades gerenciais do Enfermeiro em relação ao trabalho dos agentes comunitários de saúde necessitam estar alicerçadas em políticas públicas que visem apoiar as práticas cotidianas, promovam as atualizações multiprofissionais e possibilitem que processo de trabalho de atenção básica seja de qualidade e possa impactar na qualidade de vida das populações adstritas.
Review on enhanced oil recovery by nanofluids
Authors: Li Kewen , Wang Dan , Jiang Shanshan
Published: October 2018

The addition of nanoparticles into water based fluids (nanofluid) with or without other chemicals to Enhance Oil Recovery (EOR) has recently received intensive interest. Many papers have been published in this area and several EOR mechanisms have been proposed. The main EOR mechanisms include wettability alteration, reduction in InterFacial surface Tension (IFT), increase in the viscosity of aqueous solution, decrease in oil viscosity, and log-jamming. Some of these mechanisms may be associated with the change in disjoining pressure because of the addition of the nanoparticles. The experimental data and results reported by different researchers, however, are not all consistent and some even conflict with others. Many papers published in recent years have been reviewed and the associated experimental data have been analyzed in this paper in order to clarify the mechanisms of EOR by nanofluids. Wettability alteration may be one of the most accepted mechanisms for nanofluid EOR while reduction in IFT and other mechanisms have not been fully proven. The main reason for the inconsistency among the experimental data might be lack of control experiments in which the effect of nanoparticles on oil recovery would be singled out.

Peraturan Pemerintah (PP) Nomor 1 Tahun 2017 which has been officially legalized by the Government of Indonesia in effort to encourage the establishment of smelter facilities in the country have an impact on mining companies, especially on the company's debt policy. This research aims to study the effect of institutional ownership, dividend payout ratio, tangibility, and firm size on company debt policy as measured by debt ratio. This research uses multiple linear regression analysis with secondary data in the form of annual reports and audited financial statement from mining sector companies listed on the Indonesia Stock Exchange in 2013-2015 period. From total population of 43 companies in the mining sector, 32 companies were selected to be the sample of this research with a total of 96 observations in 3 years. The results of this research indicate that from the four independent variables tested, institutional ownership and dividend payout ratio has an influence on debt policy, while tangibility and firm size have no influence on debt policy.
PHoS: Persistent Homology for Virtual Screening
Authors: Keller Bryn , Lesnick Michael , Willke Theodore L.
Published: October 2018

Finding new medicines is one of the most important tasks of pharma- ceutical companies. One of the best approaches to finding a new drug starts with answering this simple question: Given a known effective drug X, what are the top 100 molecules in our database most similar to X? Thus the essence of the problem is a nearest-neighbors search, and the key question is how to define the distance between two molecules in the database. In this paper, we investigate the use of topological, rather than geometric, or chemical, signatures for molecules, and two notions of distance that come from comparing these topological signatures. We introduce PHoS (for Persistent Homology-based virtual Screening), a new system for ligand-based screening using a topological technique known as multi-parameter persistent homology. We show that our approach can match or exceed a reasonable estimate of current state of the art (including well-funded commercial tools), even with relatively little domain-specific tuning. Indeed, most of the components we have built for this system are general-purpose tools for data science and will be released soon as open source software.
Control of Metal–Organic Framework Crystallization by Metastable Intermediate Pre-equilibrium Species

There is an increasingly large amount of interest in metal-organic frameworks (MOFs) for a variety of applications, from gas sensing and separations to electronics and catalysis. Their exciting properties arise from their modular architectures, which self-assemble from different combinations of metal-based and organic building units. However, the exact mechanisms by which they crystallize remain poorly understood, thus limiting any realisation of real “structure by design”. We report important new insight into MOF formation, gained using in situ X-ray diffraction, pH and turbidity measurements to uncover for the first time the evolution of metastable intermediate species in the canonical zeolitic imidazolate framework system, ZIF-8. We reveal that the intermediate species exist in a dynamic pre-equilibrium prior to network assembly and, depending on the reactant concentrations and the progress of reaction, the pre-equilibrium can be made to favour under- or over-coordinated species, thus accelerating or inhibiting crystallization, respectively. We thereby find that concentration can be effectively used as a synthetic handle to control particle size, with great implications for industrial scale-up and gas sorption applications. These finding enables us to rationalise the apparent contradictions between previous studies and, importantly, opens up new opportunities for the control of crystallization of network solids more generally, from the design of local structure to assembly of particles with precise dimensions.
Accurate and Transferable Multitask Prediction of Chemical Properties with an Atoms-in-Molecule Neural Network
Authors: Zubatyuk Roman , Smith Justin S. , Leszczynski Jerzy , Isayev Olexandr
Published: October 2018

Atomic and molecular properties could be evaluated from the fundamental Schrodinger’s equation and therefore represent different modalities of the same quantum phenomena. Here we present AIMNet, a modular and chemically inspired deep neural network potential. We used AIMNet with multitarget training to learn multiple modalities of the state of the atom in a molecular system. The resulting model shows on several benchmark datasets the state-of-the-art accuracy, comparable to the results of orders of magnitude more expensive DFT methods. It can simultaneously predict several atomic and molecular properties without an increase in computational cost. With AIMNet we show a new dimension of transferability: the ability to learn new targets utilizing multimodal information from previous training. The model can learn implicit solvation energy (like SMD) utilizing only a fraction of original training data, and archive MAD error of 1.1 kcal/mol compared to experimental solvation free energies in MNSol database.
Isotope Depletion Mass Spectrometry (ID-MS) for Enhanced Top-Down Protein Fragmentation
Authors: Gallagher Kelly J. , Palasser Michael , Hughes Sam , Mackay C. Logan , Kilgour David P. A. , Clarke David
Published: October 2018

Top-down mass spectrometry has become an important technique for the identification of proteins and characterisation of chemical and posttranslational modifications. However, as the molecular mass of proteins increases intact mass determination and top-down fragmentation efficiency become more challenging due to the partitioning of the mass spectral signal into many isotopic peaks. In large proteins, this results in reduced sensitivity and increased spectral complexity and signal overlap. This phenomenon is a consequence of the natural isotopic heterogeneity of the elements which comprise proteins (notably 13C). Here we present a bacterial recombinant expression system for the production of proteins depleted in 13C and 15N and use this strategy to prepare a range of isotopically depleted proteins. High resolution MS of isotope depleted proteins reveal dramatically reduced isotope distributions, which results in increases in sensitivity and deceased spectral complexity. We demonstrate that the monoisotopic signal is observed in mass spectra of proteins up to ~50 kDa. This allows confident assignment of accurate molecular mass, and facile detection of low mass modifications (such as deamidation). We outline the benefits of this isotope depletion strategy for top-down fragmentation. The reduced spectral complexity alleviates problems of signal overlap; the presence of monoisotopic signals allow more accurate assignment of fragment ions; and the dramatic increase in single-to-noise ratio (up to 7-fold increases) permits vastly reduced data acquisition times. Together, these compounding benefits allow the assignment of ca. 3-fold more fragment ions than analysis of proteins with natural isotopic abundances. Thus, more comprehensive sequence coverage can be achieved; we demonstrate near single amino-acid resolution of the 29 kDa protein carbonic anhydrase from a single top-down MS experiment. Finally, we demonstrate that the ID-MS strategy allows far greater sequence coverage to be obtained in time limited top-down data acquisitions – highlighting potential advantages for top-down LC-MS/MS workflows and top-down proteomics.

Published: October 2018

At present a steady increase of obesity prevalence is observed all over the world. It is known that specifically visceral obesity is associated with high risk of cardiovascular disease and their complications development, but the available verification methods do not determine the real visceral adipose tissue volume accurately. The importance of localized fat depot as a risk factor for cardiovascular diseases and as an early marker of target organs damage in obese patients is discussed in the review. An alternative method of epicardial adipose tissue thickness determined with the use of echocardiography used as waist circumference analogue for a more precise evaluation of visceral obesity in everyday practice is reviewed.

Published: October 2018

O bruxismo compreende uma atividade parafuncional caracterizado pelo ato de ranger ou apertar os dentes de forma voluntária e/ou involuntariamente, ocorrendo durante o período diurno e/ou noturno, podendo acarretar vários prejuízos ao sistema estomatognático. Diversos são os fatores etiológicos que podem estar associados a esta desordem, como fatores locais, sistêmicos, hereditários, psicossociais e comportamentais. Pesquisadores têm sugerido que fatores comportamentais, como estresse, ansiedade e traços de personalidade se sobressaem a fatores locais. Portanto, o objetivo deste estudo foi realizar uma revisão sistemática da literatura a fim de avaliar se há relação entre bruxismo e fatores psicológicos em crianças. Foram realizados levantamentos nas bases de dados: PubMed, BVS Biblioteca Virtual em Saúde e SciELO no período de fevereiro de 2007 a setembro de 2017. Os descritores utilizados foram “bruxism”, “children”, “stress”, “anxiety”, “pshychological factors”. Sendo assim, 97 publicações foram identificadas na busca inicial. Após aplicação dos critérios de inclusão e exclusão, a amostra final foi composta por sete estudos. Houve evidência significativa de uma associação entre estresse, ansiedade e fatores psicológicos com o bruxismo infantil. Porém, ainda existe uma enorme necessidade de estudos bem delineados e com metodologias padronizadas a fim de verificar a associação entre o bruxismo e fatores psicológicos.

Foi avaliada a eficácia dos fitoterápicos em situações como pulpotomia, controle de biofilme, tratamento de aftas e controle da ansiedade ao tratamento odontológico. Em todas as situações, os resultados foram positivos quanto ao uso da fitoterapia.
A Grounded Theory for ICT-Mediated Tacit Knowledge Transferability in MNCs
Authors: Sharaf Qdah Mohammad , Nizar Fayez AbuAli Amer , Salim Juhana , Issa Khalil Tarek
Published: October 2018

Aim/Purpose: A vital business activity within organizations is tacit knowledge (TK) transfer. This work aims to propose a novel framework for TK transferability in multinational corporations (MNCs) from the information and communication technology (ICT) perspective.

Background: In the past two decades, researchers have developed several frameworks for TK transfer based on humanistic, business, and educational perspectives. However, a review of the existing work revealed that TK transfer has seldom been examined from an ICT perspective.

Methodology: A qualitative method was adopted because it was considered the most appropriate for the research requirements. A grounded theory approach was employed to generate the items that potentially affect the transferability of TK. Face-to-face semi-structured interviews were conducted to collect data, along with observations when possible. The study sample consisted of 20 expert interviewees in Malaysia. An inductive ongoing data analysis process based on grounded theory via open, axial, and selective coding was used as the primary analysis method. In addition, comparative and frequency count analyses were used to examine the collected data.

Contribution: The main contribution of this study is its use of the grounded theory approach, which resulted in the generation of items that affect the transferability of TK, not all of which had been identified by previous researchers. This paper reports one of the few inductive studies conducted on TK transferability among MNCs and, therefore, makes distinct contributions to the literature on TK management, specifically bringing to the fore the intricacies involved in TK transferability.

Findings: Information and communication technology plays a crucial role in and has a positive impact on TK transfer in MNCs. This study evaluated the potential of various ICT channels to facilitate TK transfer. The findings show that ICT tools cannot completely substitute for face-to-face contact. Tacit knowledge that has a high degree of complexity requires sophisticated channel features for its transfer. From this standpoint, virtual face-to-face communication is the richest communication medium in the ICT hierarchy. On the other hand, email and voicemail are less effective channels for TK transfer, while synchronous groupware is an intermediate communication medium. The findings highlight the importance of utilizing an appropriate mix of channels to improve TK transferability.

Recommendations for Practitioners: It is recommended that practitioners consider the diverse aspects of TK and the potential of a range of ICT channels for the TK transfer process in order to increase the efficiency of TK transfer. The analytic categories developed in this study may give managers new insights into and a better understanding of how TK can be supported in a modern organization and how to overcome the barriers to TK transfer.

Published: October 2018

The ongoing transfer of non-indigenous organisms through shipping, especially via ballast water transport, is placing marine and coastal resources under increased threat. The transport of Invasive Alien Species (IAS) is a critical issue which may cause irreversible consequences to receiving environments and economies needing particular attention. The main objective of this paper is to highlight the importance for implementation of ballast water management measures in Brunei Darussalam. This paper recognised IAS intrusion via ballast water has high probability to have direct effects on the economic value of fisheries sector, thus the need for an effective ballast water management strategy. Management of ballast water is a complex issue and horizontal policy is the appropriate approach for building this management framework in addition to valid baseline and efficient monitoring. Further studies such as development risk assessment model and assessment of different management measures are critical for an effective prevention, eradication and control strategy.
Plate Settlement: Determination of Fouling Organisms in Brunei
Authors: Jolkifli Hjh Zuliza Hj , Wahab Ranimah H.A
Published: October 2018

Shipping is considered a primary vector of biological invasion. Hull fouling is recognized as one of the common vectors involved in the translocation of marine pests that may have deleterious impacts to ecology and economy. In an effort to understand the fouling communities within Brunei waters and as an early attempt to obtain baseline data, PVC plates were deployed at a depth of 1 meter, checked for taxa composition and replaced with new plates monthly and quarterly over a period of one year. The Caribbean bivalve Mytilopsis sallei was absent throughout the period of study, and plates were mainly colonized by native fouling species and silt. Nevertheless, further verification on the absence of Invasive Alien Species (IAS) is still required. This study summarizes the improved methods of analysis for better control and management in order to impede the incursion or invasion of undesirable species.
Numerical Modelling of Ballast Water Dispersion in Different Bioregions along the Coast of India
Authors: Babu M.T. , Sudheesh K , Vethamony P , Anuvindha S
Published: October 2018

Aquatic organisms and pathogens may become major threats to the coastal and marine environment when introduced into a region beyond their natural distributions through ballast water (BW). Coastal currents induced by tides and winds, especially ebb currents, may facilitate the spread of these marine organisms along nearshore and inshore areas. Numerical modelling of hydrodynamics is an effective tool to track the dispersion of these organisms in the receiving water body through BW release. Particle transport models can be used to track the advection and dispersion of these organisms. Alternatively, the difference in salinity of the BW and coastal waters can be used as a tracer to estimate the dispersion pattern. Tides and winds present in the region at the time of BW release are responsible for the dispersal of the particles present in BW discharge. Based on advection and dispersion processes, the transport of the marine organisms present in the BW can be studied using numerical models. Numerical modelling studies were carried out using the 2-D hydrodynamic model MIKE21 HD, to understand the pattern of BW dispersion at select bioregions along the east and west coasts of India. Mangalore Port located along the west coast in Bioregion-I (CIO-I) and Chennai Port on the east coast in Bioregion-II (CIO-II) were selected for the modelling study. Results obtained from ballast water dispersion modelling studies will be useful for developing and assisting port-based ballast water management programmes for CIO-I and CIO-II regions. The currents are predominantly tide driven near the ports situated along the west coast and the circulation exhibited reversals associated with the tidal currents. However, along the east coast of India, the particles largely followed coastal currents - advected either southward or northward under the influence of prevailing coastal currents in the offshore region and tidal reversals showed had less impact. This information proved useful for determining suitable locations for BW discharge and monitoring points for field sampling in connection with BW release.

Authors: Desai Dattesh V , Krishnamurthy Venkat , Anil Arga Chandrashekar
Published: October 2018

Biofouling community structure was studied in a tropical monsoon-influenced Mandovi estuary in Goa, west coast of India. Monthly, seasonal and yearly observations on biofouling on polyvinyl chloride (PVC) panels immersed at subsurface water level were recorded and photographed from May 2012 to September 2013. The barnacle Balanus amphitrite was the dominant fouling organism followed by calcareous polychaetes. The settlement and recruitment of barnacles took place year-round, with the exception of July 2012 and June 2013 (monsoon months). However, their peak abundance was observed during the later months of monsoon (August and September). Polychaetes were dominant during late post-monsoon and pre-monsoon months (December 2012 to April 2013). Silt and slime were observed throughout the observation period. Comparing the fouling pressure of barnacles in the two monsoon seasons (2012 and 2013), fouling was more intense during the monsoon of 2013, indicating an inter-annual variation in the fouling community.
Recent Trends of Demersal Marine Fish and Invertebrate Production in Southeast Asia – A Hypothesis-based Analysis
Authors: Padate Vinay P. , Rivonker Chandrashekher U.
Published: October 2018

Demersal marine fish and invertebrate production data for Southeast Asia (1996–2007) obtained from the Southeast Asian Fisheries Development Center (SEAFDEC) statistical bulletin indicated a reduced production by Thailand largely due to over-exploitation and altered coastal ecosystems. In contrast, increased production by Philippines, Indonesia and Malaysia was due to an increase in mechanised fishing fleets. Moreover, marginal increases in the ecosystem indicators were attributed to increased exploitation of high and mid trophic level organisms suggesting the development of “top-down” cascade effect in the future. In this bioregion, land use pattern affecting water quality coupled with altered monsoonal sequences and rising sea surface temperatures interfere with biological processes. The most apparent manifestations of these disturbances are recurrences of extensive algal blooms and coral bleaching events. Fish mortality as a result of these events threatens to weaken the native biota and facilitate invasions that would modify the trophic dynamics of the coastal habitats.
Industrial Seawater Cooling Systems under Threat from the Invasive Green Mussel Perna viridis
Authors: Venugopalan Vayalam P.
Published: October 2018

The green mussel Perna viridis, native to the Asia-Pacific region, has been introduced to other regions such as the Caribbean, Japan and North and South America. It is a large, commercially important species, widely cultivated and harvested in Southeast Asia, but is also considered an invasive species elsewhere, capable of replacing native species. As a fouling organism in intake systems of coastal power plants, it causes flow blockage and loss of cooling efficiency. Mussel colonization during peak settlement season can exceed 35,000 individuals/m2 and biomass can exceed 100 kg/m2. They can withstand wide fluctuations in temperature and salinity. Previous work has shown that a conventional biofouling control measure such as chlorination is not very effective against these bivalves, unless applied continuously for extended periods of time. We require more efficient, environmentally compatible methods of biofouling control. The paper discusses these issues in the context of the perceived invasion potential of P. viridis.
Marine Fouling Panel Survey and Assessment of Marine Alien Invasive Species in Myanmar
Authors: Khaing Myint Myint
Published: October 2018

A survey on fouling using PVC panels was carried out for a period of one year in Yangon River. Additional observations on fouling of man-made structures elsewhere in Myanmar were also made in an effort to find marine alien invasive species. The Myanmar ports at Yangon, Sittway and Myeik have a long history of overseas trading with Europe since the 17th century. In addition, though the Yangon port and jetties are located upstream some 12 miles from the mouth of Yangon River, it experiences regular tidal action with seasonal brackish water conditions. Its catchment area is only 100 miles from the mouth and hence the river and its tributaries are short and small. Moreover, there are several weirs and small dams on the tributaries, which result in reduced sediment influx at the mouth and thus less turbidity. Therefore, the physiochemical conditions at Yangon port may not pose a limitation on the distribution of nuisance species that are able to survive brackish water conditions. Elsewhere, Sittway port at the mouth of the Kispanadi River also experiences regular tidal action and is directly connected to the Bay of Bengal, conditions which are favourable for the intrusion of marine nuisance species. Myeik port is located along the open shore of the Myeik, which is located near the Myeik Archipelago. The waters around the archipelago are clear and the shelf is characterized by high biodiversity. Therefore, the environment also appears to be highly favourable for alien invasive species. However, these ports have no record of the occurrence of alien invasive species in particular the Caribbean bivalve Mytilopsis sallei.

Published: October 2018

Marine phytoplankton was investigated in ballast water of ships from 2010 to 2012 with a collection of 30 marine vessels that docked at Laem Chabang International Port in Chonburi Province, Thailand. The results showed that the dominant group of phytoplankton was diatoms. The amount of phytoplankton in the ballast tanks averaged less than 10 cells/ mL, which is less than Regulation D-2 of the Ballast Water Management Convention which requires that marine organisms between the sizes of 10 ? X <50 µm should be less than 10 cells/mL and size ? 50 µm should be less than 10 cell/m3 in ballast water. Alien species of phytoplankton was not recorded in this survey.

The fouling organisms at Songkhla Port were investigated from November 2011 to December 2012. Samples were collected using PVC panels (10 cm x 20 cm) submerged for one-month and three-month periods. Analysis of fouling panels was carried out using PhotoGrid software. In addition to slime and silt, three types of fouling organisms, namely encrusting bryozoa, barnacles and calcareous polychaetes, were observed on the submerged PVC panels. Calcareous polychaetes and molluscs were the most diverse groups (ten species) on panels that were submerged for one-month and three-month periods. Barnacles (Balanus spp.) were most abundant on panels submerged for three-month periods, while calcareous polychaetes dominated one-month panels. The dominant species of mollusc was the mussel Brachidontes sp. The major polychaetes identified were Ficopomatus macrodon, F. enigmaticus and Hydroides norvegicus. A highlight of this study was the first record of the Caribbean tubeworm Hydroides sanctaecrucis in Thailand, which has previously invaded and established in Australian waters through hull fouling.

Limited knowledge of native marine biodiversity hinders effective biodiversity management to safeguard South and Southeast Asia’s marine coastal environment against the threat of invasive species transfer through shipping. In particular, sessile marine biofouling organisms in South East Asian ports are poorly known. Through the support of the ASEAN-India Cooperation Project on the Extent of Transfer of Alien Invasive Organisms in South/South East Asia Region by Shipping, a coordinated effort to examine diversity of biofouling organisms in major port areas in Southeast Asia and India was made using polyvinylchloride (PVC) panels as recruitment surfaces in a static immersion study for a period of 12 months. Not surprisingly, the study revealed that fouling patterns differed between ports possibly as a result of dissimilar hydrographic conditions. However, there were also underlying similarities that reflected a regional uniformity in the composition of fouling communities. At the same time, the alien Caribbean bivalve Mytilopsis sallei was detected in Manila Bay (Philippines), Songkhla Port (Thailand) and Singapore. This is a first simultaneous biofouling survey involving scientists and government stakeholders from India and ASEAN nations of Brunei Darussalam, Indonesia, Lao PDR, Malaysia, Myanmar, Singapore, Thailand, Philippines and Vietnam.
