Risk Assessment of Boot Hydropower Projects in Nepal Using Fuzzy Logic Approach
Authors: Tripathi Pramesh , Shrestha Santosh Kumar
Published: January 2018

Many Hydropower Projects in Nepal are carried out with insufficient risk assessment because of which time over run or variations are predominant. Many projects are stuck in preconstruction phase and others in construction phase. In this study all possible risks associated with the BOOT Hydropower Project in Nepal were identified and evaluated. Fuzzy rating tool has been used to quantify the risk associated with the BOOT Hydropower Projects in Nepal. It provides a flexible and easily understood way to analyze the project risks.  The relative importance (impact) of risk factors was determined from the survey results. A set of questionnaire was prepared for the survey. The survey was conducted with the experts that have experience in BOOT hydropower projects. From the survey, among the type of risks, Grid Connection / Power Evacuation, Political risk and Geological risk were found to be predominant risk respectively in BOOT hydropower projects in Nepal. The risk assessment method enabled a Risk Index (R) value to be calculated, establishing a 4-grade evaluation system: low risk having R values between 1.17 and 1.69; medium risk, between 1.69 and 2.08; high risk, between 2.08 and 2.47; extreme risk, between 2.47 and 2.78. Applicability of the methodology was tested on a real case hydropower project namely Middle Modi Hydroelectric Project (15.1 MW) which is in construction phase on Modi River in Western Region in Nepal and Madhya Bhotekosi Jalavidyut Company Ltd. (102 MW) which is also in construction phase on Bhotekoshi River in Central Region in Nepal.  The risk analysis method will give investors a more rational basis on which to make decisions and it can prevent cost and schedule overruns. An overall risk index can be used as early indicators of project problems or potential difficulties. Evaluators can keep track to evaluate the current risk level with the progress of investments.

Authors: Chen Xiaoxian , Zhan Yongzhong , Han Feng , Guo Fuda , Wei Chengxia
Published: January 2018

The phase equilibria in the Al–Mo–Y system have been experimentally investigated at 873 K. The existence of 10 binary compounds and 1 ternary phase Al43Mo4Y6 has been confirmed by using X-ray powder diffraction and scanning electron microscopy equipped with energy dispersive X-ray analysis. A new ternary phase Al4Mo2Y with space group I4/mmm (No. 139) has been found at 873 K. The structure, phase stability, elastic properties and densities of state of the Al4Mo2Y compound have been theoretically investigated by using first-principles calculations. The result of cohesive energy proves that Al4Mo2Y is stable. The elastic constants, bulk modulus, shear modulus, Young's modulus, the ratio of bulk modulus/shear modulus and Poisson's ratio of Al4Mo2Y are presented. According to the phase-disappearing method, the solubility of Al in Mo, AlMo3 and Al8Mo3 phase is determined to be about 16 at.%, 7.5 at.% and 1 at.%, respectively.

Authors: Camargo Nelson Heriberto Almeida , Gemelli Enori , Passoni Laís Schmitz , Franczak Priscila Ferraz , Corrêa Pricyla
Published: January 2018

A hydroxyapatite and tricalcium phosphate nanocomposite containing 5% silica was developed for dental applications. The biomaterial was prepared by one-step synthesis via the wet route. The resulting dry material consisted of hydrated calcium phosphate agglomerates with sizes of up to 200 μm. The presence of silica was found to lower the phase transformation temperature of the calcium phosphates and increase the open porosity of the biomaterial compared to that of hydroxyapatite. The hydrated calcium phosphate transformed into hydroxyapatite (HA) and beta tricalcium phosphate (TCP) at approximately 682 °C. After 2 h of calcination at 900 °C, the volume ratios of HA and TCP in the nanocomposite were 84 and 16%, respectively. The open porosity in the triphasic nanocomposite and in the HA was 46.35% and 41.52%, respectively, after 3 h of sintering at 1 100 °C. Samples of grade 2 titanium were sandpapered and etched with an acid solution of HCl/H2SO4 prior to deposition of the calcined nanocomposite. The particles were deposited homogeneously and reduced the contact angle of the titanium surface.
Kinetics and Mechanism of Acetalisation of Furfural to Furfural Diethyl Acetal with Ni–Al Layered Double Hydroxides Containing Lewis Acid Sites
Authors: Du Yali , Feng Yalin , Zou Chunlei , Wu Xu , Huang Wei
Published: January 2018

The nitrate form of Ni–Al layered double hydroxide (denoted as Ni–Al–NO3-LDH) and the corresponding carbonate form (denoted as Ni–Al–CO3-LDH) were tunably fabricated by the hexamethylenetetramine hydrolysis method. A catalytic behaviour investigation proved Ni–Al–CO3-LDH to be an ineffective catalyst, while for Ni–Al–NO3-LDH excellent catalytic activity and reusability were obtained, in the acetalisation of furfural to furfural diethyl acetal. Characterisation and analysis revealed that the appearance of Lewis acid sites in Ni–Al–NO3-LDH was responsible for its excellent catalytic performance. The acquired kinetic parameters confirmed that this reaction was a first-order process and the apparent activation energy was 36.28 kJ mol−1, which is in reasonable agreement with the theoretical result of 38.57 kJ mol−1. Additionally, apart from the typical Brønsted acid catalytic mechanism, a possible Lewis acid catalytic mechanism was probed theoretically.

Published: January 2018

In this study, central composite design (CCD) was used for optimization of high performance liquid chromatographic (HPLC) method for simultaneous analysis of curcumin (CUR) and demethoxycurcumin (DMC) in tablets containing Curcuma extract. Separation of CUR and DMC was performed using X-Bridge C18 column (250 x 4.6 mm i.d; 5 μm). Four factors that were investigated include the concentration of acetic acid (X1), ratio of acetic acid (X2), flow rate of mobile phase (X3) and column temperature (X4). Based on responses obtained (retention time, peak area, resolution and tailing factor), the optimum condition selected was X1 = 3.00%, X2 = 51%, X3 = 1.05 mL/min and X4 = 45oC. This HPLC condition was validated by assessing several validation parameters including system suitability test, selectivity, linearity, precision, accuracy and robustness according to International Conference Harmonization (ICH). All validation parameters meet the acceptance criteria set by ICH. The validated method was successfully used for analysis of CUR and DMC in tablets containing Curcuma extract. CCD was effective means in optimization of HPLC for analysis of CUR and DMC in pharmaceutical formulation.Dhaka Univ. J. Pharm. Sci. 16(2): 137-145, 2017 (December)
Comparative Phytochemical, Antioxidant and Antimicrobial Properties of Ficus capensis, Aristolochia ringens, Albizia zygia and Lannea welwitschii
Authors: Obonga Wilfred O , Uzor Philip F , Ekwealor Emmanuel O , Nwabuko Sampson C
Published: January 2018

The present study was aimed at a comparative study of the phytoconstituents, antioxidant and antimicrobial properties of four medicinal plants, Ficus capensis, Aristolochia ringens, Albizia zygia and Lannea welwitschii. The leaf of F. capensis and stem bark of A. ringens, A. zygia and L. welwitschii were extracted using methanol. Phytochemical analysis was done spectrophotometrically. Three in vitro antioxidant tests-hydrogen peroxide (H2O2), nitric oxide (NO) and 2, 2-diphenyl-1-picrylhydroxyl (DPPH) scavenging models were employed. Antimicrobial test was done by agar diffusion method against E. coli, Staphylococcus aureus, Klebsiela pneumonia, Bacillus subtilis, Pseudomonas aeruginosa, Salmonella typhi, Candida albicans and Aspergittus spp. Phytochemical analysis revealed that the most abundant phytoconstituents were flavonoids (F. capensis and A. zygia), reducing sugar, terpenoids, alkaloids and tannins. In the antioxidant models, A. zygia was found to produce the least IC50 in two of the models (NO and DPPH). Results of the antimicrobial tests showed that A. zygia showed a broader spectrum of activity than other plants. This study has shown that these plants possess antioxidant and antimicrobial activities which further justify their usage in traditional medicines. A. zygia featured prominently in these activities. Also flavonoids could be responsible for the bioactivities of these plants.Dhaka Univ. J. Pharm. Sci. 16(2): 147-157, 2017 (December)
Cissus quadrangularis Linn. Extract Reduces High Glucose Induced Inhibition of In Vitro Proliferation and Matrix Mineralization in MG-63 Cells
Authors: Gupta Madhu , Arshad Md
Published: January 2018

The aim of this study was to evaluate the effect and mechanism of action of ethanolic extract of Cissus quadrangularis Linn. stem in an in vitro system using MG-63 (osteoblast-like) cells. Cells were pre-exposed to high glucose (45 mmol/l). Insulin was used as positive control. To determine whether C. quadrangularis (CQ) extract could prevent hyperglycaemia induced oxidative stress, and apoptosis we performed reactive oxygen species generation using 2’,7’-dichlorofluorescin diacetate and propidium iodide staining for apoptosis. For cell proliferation, we carried out cell viability (MTT) assay. Further, alkaline phosphate assay and alizarin staining were done to study the matrix mineralization. High glucose (45 mmol/l) significantly (P < 0.001) inhibited the cell viability and matrix mineralization, and induced apoptosis as compared to physiological control. C. quadrangularis extract as well as insulin treatment significantly (p < 0.001 versus high glucose) restored the cell viability, cell differentiation and bone nodule formation. Thus, ethanolic extract of C. quadrangularis stem prevents the antiproliferative effect of high glucose.Dhaka Univ. J. Pharm. Sci. 16(2): 159-164, 2017 (December)
Developing Automatic Form and Design System Using Integrated Grey Relational Analysis and Affective Engineering
Authors: Liu Chen-Yuan , Tong Lee-Ing
Published: January 2018

In the modern highly competitive marketplace and global market environment, product quality improvements that abridge development time and reduce the production costs are effective methods for promoting the business competitiveness of a product in shorter lifecycles. Since the design process is the best time to control such parameters, systematically designing the processes to develop a product that more closely fits the demand requirements for the market is a key factor for developing a successful product. In this paper, a combined affective engineering method and grey relational analysis are used to develop a product design process. First, design image scale technology is used to acquire the best the design criteria factors, and then affective engineering methods are used to set the relationships between customer needs and production factors. Finally, grey relational analysis is used to select the optimal design strategy. Using this systematic design method, a higher quality product can be expanded upon in a shorter lead-time for improving business competition.
Spooky Action at a Temporal Distance
Authors: Adlam Emily
Published: January 2018

Since the discovery of Bell’s theorem, the physics community has come to take seriously the possibility that the universe might contain physical processes which are spatially nonlocal, but there has been no such revolution with regard to the possibility of temporally nonlocal processes. In this article, we argue that the assumption of temporal locality is actively limiting progress in the field of quantum foundations. We investigate the origins of the assumption, arguing that it has arisen for historical and pragmatic reasons rather than good scientific ones, then explain why temporal locality is in tension with relativity and review some recent results which cast doubt on its validity.

Mediterranean Diet and Other Dietary Patterns in Primary Prevention of Heart Failure and Changes in Cardiac Function Markers: A Systematic Review
Authors: Sanches Machado d’Almeida Karina , Ronchi Spillere Stefanny , Zuchinali Priccila , Corrêa Souza Gabriela
Published: January 2018

Background: Heart failure (HF) is a complex syndrome and is recognized as the ultimate pathway of cardiovascular disease (CVD). Studies using nutritional strategies based on dietary patterns have proved to be effective for the prevention and treatment of CVD. Although there are studies that support the protective effect of these diets, their effects on the prevention of HF are not clear yet. Methods: We searched the Medline, Embase, and Cochrane databases for studies that examined dietary patterns, such as dietary approaches to stop hypertension (DASH diet), paleolithic, vegetarian, low-carb and low-fat diets and prevention of HF. No limitations were used during the search in the databases. Results: A total of 1119 studies were identified, 14 met the inclusion criteria. Studies regarding the Mediterranean, DASH, vegetarian, and Paleolithic diets were found. The Mediterranean and DASH diets showed a protective effect on the incidence of HF and/or worsening of cardiac function parameters, with a significant difference in relation to patients who did not adhere to these dietary patterns. Conclusions: It is observed that the adoption of Mediterranean or DASH-type dietary patterns may contribute to the prevention of HF, but these results need to be analyzed with caution due to the low quality of evidence.
Capturing complexity in clinician case-mix: classification system development using GP and physician associate data
Authors: Halter Mary , Joly Louise , de Lusignan Simon , Grant Robert L , Gage Heather , Drennan Vari M
Published: January 2018

Background

There are limited case-mix classification systems for primary care settings which are applicable when considering the optimal clinical skill mix to provide services.

Aim

To develop a case-mix classification system (CMCS) and test its impact on analyses of patient outcomes by clinician type, using example data from physician associates’ (PAs) and GPs' consultations with same-day appointment patients.

Design & setting

Secondary analysis of controlled observational data from six general practices employing PAs and six matched practices not employing PAs in England.

Method

Routinely-collected patient consultation records (PA n = 932, GP n = 1154) were used to design the CMCS (combining problem codes, disease register data, and free text); to describe the case-mix; and to assess impact of statistical adjustment for the CMCS on comparison of outcomes of consultations with PAs and with GPs.

Results

A CMCS was developed by extending a system that only classified 18.6% (213/1147) of the presenting problems in this study's data. The CMCS differentiated the presenting patient’s level of need or complexity as: acute, chronic, minor problem or symptom, prevention, or process of care, applied hierarchically. Combination of patient and consultation-level measures resulted in a higher classification of acuity and complexity for 639 (30.6%) of patient cases in this sample than if using consultation level alone. The CMCS was a key adjustment in modelling the study’s main outcome measure, that is rate of repeat consultation.

Conclusion

This CMCS assisted in classifying the differences in case-mix between professions, thereby allowing fairer assessment of the potential for role substitution and task shifting in primary care, but it requires further validation.
Nematic topological defects positionally controlled by geometry and external fields
Authors: Kurioz Pavlo , Kralj Marko , Murray Bryce S , Rosenblatt Charles , Kralj Samo
Published: January 2018

Using a Landau–de Gennes approach, we study the impact of confinement topology, geometry and external fields on the spatial positioning of nematic topological defects (TDs). In quasi two-dimensional systems we demonstrate that a confinement-enforced total topological charge of m > 1/2 decays into elementary TDs bearing a charge of m = 1/2. These assemble close to the bounding substrate to enable essentially bulk-like uniform nematic ordering in the central part of a system. This effect is reminiscent of the Faraday cavity phenomenon in electrostatics. We observe that in certain confinement geometries, varying the correlation length size of the order parameter could trigger a global rotation of an assembly of TDs. Finally, we show that an external electric field could be used to drag the boojum fingertip towards the interior of the confinement cell. Assemblies of TDs could be exploited as traps for appropriate nanoparticles, opening several opportunities for the development of functional nanodevices.

Published: January 2018

Introduction: H9N2 avian influenza viruses (AIV) can transmit in chicken flocks through direct contact and aerosols. Nevertheless, data on airborne transmission of AIV is very limited, especially under field conditions. To fill this literature gap, this study was designed to investigate airborne transmission of H9N2 AIV originating from infected chicken flocks under field conditions, with the aim to further characterize the airborne transmission of H9N2 AIV.

Methodology: Oropharyngeal swabs were collected from different diseased chickens to confirm H9N2 AIV infection. All glass impingers 30 (AGI-30) were used to collect indoor, upwind and downwind air samples for three chicken houses with H9N2 AIV infected chickens. Swabs and air samples were tested for H9N2 AIV using a real-time reverse transcription polymerase chain reaction (RRT-PCR). H9N2 AIV was isolated in embryonated chicken eggs and hemagglutinin (HA) gene sequence similarity of the isolated AIV was compared.

Results: The results showed that indoor air samples were all RRT-PCR positive for H9N2 AIV. Downwind air samples collected between 10 m and 1.5 km away from the chicken houses were also found positive with an average load 2.62-5.21×103 RNA copies/m3. However, upwind air samples were all negative for H9N2 AIV. In addition, H9N2 AIV was isolated from swabs and indoor air samples.

Conclusion: In summary, this study provides insights into the airborne transmission of H9N2 AIV under field conditions.
Factors Determining Nephrotoxicity and Mortality in Critical Care Patients Receiving Colistin
Authors: Ciftci Ali , Izdes Seval , Altintas Neriman Defne
Published: January 2018

Introduction: We aimed to determine risk factors for nephrotoxicity and factors affecting mortality in patients who received colistin.

Methodology: Critical patients who received colistin were enrolled. Pregnancy, age < 18 years, basal creatinine level > 2 mg/dL, colistin use for < 48 hours, and previous renal replacement therapy were exclusion criteria. KDIGO stages were determined according to creatinine levels. Patients were grouped as those with no acute kidney injury (Group N0) and those with acute kidney injury (Group N). Their demographic data, APACHE II and SOFA scores, treatments, and laboratory results were recorded.

Results: A total of 91 patients were included: 27 in Group N0 and 64 in Group N. Demographic data were similar between groups; however, higher admission APACHE-II scores (OR:1.179, 95% CI:1.033-1.346, p = 0.015) and need for vasopressors (OR:5.486, 95% CI:1.522–19.769, p = 0.009) were found to be independent risk factors for nephrotoxicity. Higher APACHE II scores (OR:1.253, %95 CI:1.093-1.437, p = 0.001), presence of coronary artery disease (OR:7.720, % 95 CI: 1.613-36.956, p = 0.011), need for vasopressors (OR: 4.587, % 95 CI: 1.224 – 17.241, p = 0.024), hypoalbuminemia (OR: 4.721, % 95 CI: 1.088 – 20.469, p = 0.038), and higher direct bilirubin levels (OR: 1.806, % 95 CI: 1.055 – 3.092, p = 0.031) were independent risk factors for mortality.

Conclusion: When use of colistin is considered in ICU patients, presence of modifiable risk factors for nephrotoxicity such as hypoalbuminemia, nephrotoxic drug administration, and presence of shock should be determined and managed to prevent nephrotoxicity.
Molecular characterization of resistance mechanisms in Pseudomonas aeruginosa isolates resistant to carbapenems
Authors: Shaaban Mona , Al-Qahtani Ahmed , Al-Ahdal Mohammed , Barwa Rasha
Published: January 2018

Introduction: Emergence of carbapenem resistance in Pseudomonas aeruginosa increases the therapeutic dilemma. In this study, we investigated various mechanisms involved in the resistance of P. aeruginosa clinical isolates to carbapenems.

Methodology: P. aeruginosa isolates were isolated from different clinical samples. The antimicrobial susceptibility was evaluated by disc diffusion method. Carbapenemases were detected among carbapenem resistant isolates. Expression level of mexB and oprD was determined by real-time PCR. Molecular relatedness among isolates was detected based on pulse-field gel electrophoresis (PFGE).

Results: Ninety P. aeruginosa isolates were purified from clinical specimens. High levels of resistance to imipenem and meropenem were detected in 16 isolates. PCR analysis of carbapenemases indicated the prevalence of Verona integron-encoded metallo-beta-lactamase (VIM); four isolates produced only VIM enzymes (VIM-1 or VIM-2), while the remaining twelve co-produced both VIM-1 or VIM-2 and NDM enzymes.

Additionally, real-time PCR analysis elucidated high expression levels of mexB in seven of the carbapenem resistant isolates and low expression of oprD in seven isolates.

The identified carbapenem-resistant isolates were clustered into eleven PFGE profiles where clusters E1 and E2 involved isolates exhibiting multiple carbapenemase genes (blaNDM-1, blaVIM-1 and blaVIM-2).

Conclusion: Various mechanisms underlying carbapenem resistance have been detected in our P. aeruginosa cohort of isolates. Emergence of P. aeruginosa as a reservoir of multiple carbapenemases is increasing over time limiting the treatment options to this serious infection. This increases the urgency for infection control practices to reduce the incidence of this infection.
Évolutions et transformations des financements publics des associations

Published: January 2018

Les enquêtes périodiques intitulées « Paysage associatif » conduites par le Centre d’économie de la Sorbonne analysent les transformations intervenues en matière de financement du secteur associatif. Elles montrent une privatisation croissante des ressources de ce secteur qui demande une participation financière des usagers au service rendu, voit augmenter du poids des conseils départementaux et se transformer les modalités du financement public avec la baisse des subventions et l’explosion des commandes publiques. Ces transformations impactent le développement du secteur en développant son rôle d’instrument de mise en œuvre des politiques sociales et en sélectionnant les objectifs de ces politiques en fonction de la solvabilité de leurs publics. Enfin, elles accélèrent les inégalités de développement des tissus associatifs locaux désormais largement tributaires des capacités locales de financement.

Désaveu et pactes inconscients dans la clinique en placement familial
Authors: Cornalba Vincent
Published: January 2018

À partir de la présentation du phénomène d’adoption silencieuse, l’auteur aborde les enjeux inconscients que cette transgression du cadre est susceptible de révéler. Le recours aux notions de contrat narcissique, d’alliances inconscientes et de pactes dénégatifs apparaît comme le passage indispensable afin d’en éclairer la dynamique. La réflexion sur la fonction symbolique assurée par les familles d’accueil ouvre à des propositions sur un statut évolutif des assistants familiaux. Il s’agirait, dans certaines situations où l’absence des parents nuit au sentiment de sécurité chez l’enfant, de reconnaître l’importance d’une parentalité partagée, le temps que dure l’accueil. La complémentarité des rôles parentaux pourrait constituer pour l’enfant un socle symbolique suffisant, le soulageant de cette précarité trop souvent alimentée par le dispositif de placement actuel. Pour autant, cette avancée dans le cadre juridique et/ou administratif de l’enfant placé ne saurait faire oublier l’irréductible étranger qu’il continue d’incarner. L’oubli de cette évidence faisant le lit d’un retour de l’étranger à travers la convocation de motions inconscientes.
Le parcours précurseur de Jean Claude Rouchy. Réflexions et souvenirs sur l’enseignement du transfert dans le groupe
Authors: Darchis Élisabeth
Published: January 2018

Le parcours de Jean Claude Rouchy témoigne de l’histoire du mouvement de la psychanalyse de groupe. Rouchy s’est appuyé sur ses expériences groupales institutionnelles et associatives pour analyser les processus groupaux, notamment le transfert dans le groupe. L’espace créé dans les groupes, thérapeutiques ou de formation, permet le travail analytique sur deux types de transferts, déjà distingués par Freud : les rééditions qui répètent dans le groupe un scénario dans « du même » sans avoir conscience de remettre en scène la même chose et les éditions corrigées où il y a une distance avec ce qui se répète « dans l’identique », mais pas dans tout à fait du même. Dans les processus de groupe se déplacent transférentiellement non seulement la relation à un parent ou des séries de relations duelles, mais aussi des liens primaires et des groupes internes en rapport au groupe familial d’origine.

Estudos vêm questionando o Índice de Massa Corporal (IMC) como critério único para definição de sobrepeso e obesidade. Nosso objetivo foi verificar a correlação entre as três medidas antropométricas mais utilizadas para detecção de excesso de peso e obesidade: índice de massa corporal (IMC), circunferência de cintura (CC) e excesso de gordura corporal (%GC) através das dobras cutâneas tricipital e subescapular. Trata-se de um estudo transversal com 460 escolares voluntários de 7 a 12 anos de uma escola particular e outra pública de Canoas – Rio Grande do Sul, Brasil. A frequência de obesos, pelo percentil do IMC, foi de 51,4%; de CC foi de 25,21% e de %GC foi de 36,30% sem diferenças percentuais entre as duas escolas. A correlação entre as três medidas, com teste de Spearman, foi de r > 0,80. A forte correlação encontrada sugere que o IMC, por si só, é bom indicador para detecção de obesidade em escolares.

O objetivo do estudo foi conhecer a vivência dos usuários na realização do autocuidado com a estomia. Pesquisa qualitativa, sendo realizadas oito entrevistas com usuários do Ambulatório de Estomias da Unidade Vila dos Comerciários, no município de Porto Alegre/RS. Os dados foram submetidos à análise de conteúdo, emergindo duas temáticas: “Influência da estomia no convívio social”; “Dependência e vínculo no autocuidado com a estomia”. A estomia causa dependência para a troca do dispositivo coletor, delegando essa tarefa a um familiar treinado ou um profissional especializado. O vínculo criado pelo usuário através do sentimento de segurança de um “estar bem feito” cria uma dependência para o cuidado. A realização do autocuidado esbarra no medo de errar ao adaptar a bolsa à pele, já que o erro pode provocar uma diminuição do tempo de permanência da bolsa e gerar desperdício no número de bolsas.

This paper discusses heavy-lifting sea-transportation of 831-ton container-crane in Indonesia from Surabaya to Kupang. Structural strength analysis is carried out to ensure the safety of the crane during the transportation process. The purpose of this analysis is to design the sea-fastening construction capable of redistributing the excessive stress that might occurred, to avoid structural failure. The first step is to model the crane structure and barge under certain various drafts. This is important because selection of the proper draft will determine the suitable righting moments of barge and hence to ensure good stability. The selected drafts under investigation are taken between 0.25 T to 0.75 T. The result of the structural strength calculation shows that the static load is found around 8150 kN. Loads due to motion of barge for heave, roll, and pitch motions are 116 kN, 7424 kN, and 232kN, respectively. Location of the high stress due to the motion is identified at the bottom of the crane structure so that the design of sea-fastening constructions will be concentrated in the vicinity of this position. The values of Unity Check after fitting the sea-fastening construction are reduced to 0.940, 0.704, and 0.702, respectively. It is concluded that the structure of container crane under such sea-fastening design is proven to be capable of overcoming the loads during transportation process.

Shipbuilding as a megaproject has many uncertainties due to the overlapping design and construction activity. It is primarily driven by the substantial time and complexity involved in designing a ship and by the irregular pattern of demand from ship-owners. However, in shipbuilding operations nowadays, the role of other stakeholders has become increasingly relevant to address these issues and to improve firm's knowledge. This study argues that a characteristic of a successful shipbuilding project lies in the internal and external learning process which runs in parallel to all operations. Focusing on the small sample of firms, this paper will identify the process of routine, changes, and adaptation that is been practised and implemented across shipyards to produce a higher value product and service.

This paper presents the heading analysis study of weathervaning turret moored unit. Design wave heading is to be in accordance with the operational conditions for the sea states contributing the most to the long term value of the dominant load effect. From the heading analysis over each of the sea states contained in the time-series, the mean heading of the floating structure can be obtained.The objective of this study is to assess heading analysis outcome as function of heading probability occurrences of weathervaning turret moored floating units and to identify dominance environment load component act to the system.In order to achieve the above objective, the numerical model has been developed. The model is generate a vessel model by describing the capability to weathervane. It will be performed with MOSES software packages and numerical tools, both in the time-domain and frequency-domain.The heading analysis results indicates that the most affected external forces is dedicated by wind, it is seen the relative heading between wind and vessel heading is quite small (<10degree) with large occurrence probability (up to 60%). The proposed double static approach method to solve heading analysis has been investigated by comparing to former approach which is found a good result agreement between them.

Published: January 2018

Offshore engineering rules have been important part in supporting industrial development of tidal current energy conversion (TCEC) systems. The rules have been considered as guidelines for design of fixed type of TCEC systems, particularly those provided by European Marine Energy Centre (EMEC). However, for floating type of TCEC system, this is not the case. In fact, floating systems have a potential application for particular area of interests, for example in the area with strong currents at the seawater surface or in that with minimal infrastructure for installation support. In future, floating TCEC systems might be installed at the offshore area, even though the current application is commonly at the nearshore. Therefore, it may be beneficial to adopt relevant aspects of the offshore engineering rules for the floating structure design to support TCEC systems. This paper identifies elemental rules which may be suitable for application in the design of this type of floating structure. It includes choice of configurations, dynamic response analysis, material selection, mooring-water depth analyses and removal. This work is an important part of the whole big effort in supporting the development of ocean renewable energy industries.

Published: January 2018

Friction-stir forming (FSF) is a friction-stir process invented by Nishihara in 2002. In FSF, a material is put on a die, and friction stirring is then conducted on its back surface. The material deforms and precisely fills the cavity of the die due to high pressure and heat caused by friction stirring. Materials in the process often display outstanding deformability and moldability. However, behavior of the material during the friction-stir process has not been sufficiently clarified as a metal forming process. In this paper, material deformability under a tool in spot FSF, i.e. FSF without tool travel, was investigated employing a die having holes. The authors conducted spot FSF on 3mm-thick A5083P-O aluminum plates at offsetting points from the center of a hole and evaluated the height and volume of cylindrical extrusions to evaluate the deformability distribution under a tool. In addition, forming pressure distribution on the die surface was evaluated by an embedded pressure pin connected with a load sensor. The authors conducted spot FSF on 3mm-thick A5083P-O aluminum plates at offsetting points from the center of a pin as well as deformability tests and evaluated forming pressure compiled from the bearing load of the pin. In the deformability test, the extrusions without offsetting were shorter than the ones with 2mm offset. However, the forming pressure without offsetting was higher than the pressure with 2mm offset. Surface sink of the product without offsetting was observed below the tool probe. This implies that the probe restricts supplement of material volume to the die cavity directly below it, though it effectively extends the deformable material volume.
A Micro Constitutive Model for Ultra-High Molecular Weight Polyethylene Orthopaedic Implant Bearings
Authors: Chung Chen Yuan
Published: January 2018

Ultra-high molecular weight polyethylene (UHMWPE) is a tough semi-crystalline polymer employed widely as a bearing material in total joint replacements. The micromechanical model has been presented that predicts stiffness of UHMWPE as an aggregate of crystalline inclusions (lamellae) embedded in a rubbery matrix of amorphous polymer chains. The differential scheme was chosen for its ability to represent the interaction between an inclusion and the matrix. Numerical simulations show that increasing lamellar thickness results in less stiffness, less shear stress imposed on the lamellae, indicates that thick lamellae are desirable for UHMWPE materials utilized in total joint replacement bearings.

This research was carried out in order to study the effects that waste materials have on soil properties. As clayey soil has weak physical and mechanical properties, stabilizers are added in the soil to increase its strength .The waste materials were Palm Oil Fuel Ash (POFA) and lake water (waste water). The soil index properties was determined by carrying out the physical test and compaction test. A total of 50 samples were prepared which were tested for unconsolidated undrained Triaxial test and pH test to determine its relative mechanical and chemical properties. A shear strength of 17.80 kN/m2was obtained for the control soil specimen of the mix of 0% of POFA on 7 curing days and the same soil specimen with similar percentage of POFA had a shear strength of 18 kN/m2on 14 days. Moreover, the soil specimen of 80% of POFA and 30 % of tap water had a shear strength 44 kN/m2at 14 curing days. On the other hand, the soil specimen at 80% of POFA and 30% of Lake Water displayed a shear strength of 37 kN/m2on 14 days of curing was noted. The lake water was acidic at a pH of 6 while the tap water was at a neutral pH of 7. The control specimen (0% of POFA) of the mix of soil with tap water displayed a pH of 7 for all the curing days carried out while control soil specimen mixed with lake water displayed a ph of 6. The pH obtained increased in an alkaline way with increasing POFA percentages shear strength increased at a maximum pH of 11 at a soil specimen of 80% of POFA and 30% of Tap water proving POFA to be an alkaline material. It has been concluded that POFA, being a pozzolanic waste material can help in improving the mechanical property of the soil.

The supply of omega-3 fatty acids, which are EPA and DHA, was only 14.7% of the prospective demand calculated by using 500 mg/day/person as threshold limit for EPA and DHA consumption for a world population of 7.515 billion people. Alternative sources other than fish oil or seed-based-α linolenic acid (ALA) were necessary. Anaerobic digestion of palm oil mill effluent (POME) offered a new way for one of omega-3 fatty acids production, EPA. The digestion was conducted in anaerobic fluidized bed reactor supported by natural zeolite as the immobilization media. Process condition tried to be optimized was the pH level and the pre-treatment method (TSS filtration) before the digestion. Without any pre-treatment, the fatty acid profile produced after digestion contained considerable amount of polyunsaturated fatty acid with acidic condition provided higher EPA purity. On the other hand, pre-treatment led the digestion to produce saturated fatty acids with acidic condition provided very high purity of butyric acid as the product.
