Abstract:
AbstractWe examine the role of ocean heat flux (OHF) in Antarctic sea-ice growth and melt using data from autonomous ice mass-balance buoys deployed on pack ice in the Bellingshausen Sea and on fast ice in the Amundsen Sea during the spring/summer (October-December 2007) and summer/ autumn (February-March 2009) transitions, respectively. OHFs are derived using two methods that examine changes in (1) sub-ice ocean water properties (OHF1) and (2) ice thickness (OHF2), the latter only applying to thick snow-covered ice (i.e. a near-zero temperature gradient near the ice bottom). Good agreement is found between the time-averaged estimates of OHF1 and OHF2. Average OHF measured was 8 ± 2 W m-2 under the pack ice and 17 ± 2 W m-2 under the landfast ice. Some short-term OHF values (OHF1) in both seas exceeded 55 W m-2. The spring OHF variations in the Bellingshausen Sea were periodic and controlled by semi-diurnal ice velocity fluctuations. Larger temperature fluctuations in the summer Amundsen Sea, originating from incursions of warm deep water masses, contributed to the OHF being twice as high as in the Bellingshausen Sea and also accounted for the irregular OHF variability there.

Abstract:
The influence of five Old Home × Farmingdale (OHF) rootstocks on tree size with 10 Asian pear scion cultivars was examined after 10 years in an experimental orchard in central Washington state. The effect of rootstock on tree size varied among scion cultivars. Within `Chojuro', `Hosui', `Niitaka', and `Seigyoku', trunk cross-sectional areas were similar regardless of rootstock. Within `Li', OHF 333 produced larger trees than OHF 282 and OHF 217. `Okusankichi' trees, which were generally the same size as `Hosui', were significantly larger on OHF 217 and OHF 97 than on OHF 333. `Kikusui' trees, which were generally similar in size to `Niitaka' and `Seigyoku', were larger on OHF 217, OHF 97, and OHF 282 than on OHF 333. `20th Century', which was similar in size to `Chojuro' and `Shinseiki', appeared to be the cultivar most sensitive to rootstock. `20th Century'/OHF 217 were significantly larger than trees on OHF 97 and OHF 282, which were larger than trees on OHF 51. `Shinseiki'/OHF 97 were larger than trees on OHF 333. The smallest trees were `Shinko', with trees on OHF 217, OHF 97, OHF 333, and OHF 51 all being larger than trees on OHF 282. Contrary to research with some European pear scions, consistent trends did not emerge from this research that would allow a general prediction of the relative influence of these five OHF clonal rootstocks on Asian pear tree size.

Abstract:
Photocatalytic studies on contaminant degradation in water suspension generally suggest that the degradation reaction mainly takes place on the surface of the photocatalysts rather than in the water phase. The mechanism of selective degradation is often difficult to distinguish concerning the contribution of adsorption and radical selectivity. This study is thus designed to investigate the roles of two types of hydroxyl radicals, adsorbed hydroxyl radical (·OHa) and free hydroxyl radical (·OHf), on the selective degradation of catechol (CT) and resorcinol (RE). CT and RE are significantly different in adsorption on a TiO2 photocatalyst with a highly exposed {001} facet. CT can be selectively degraded by TiO2 and was highly correlated with adsorption. Free radical quenching experiment results showed that the degradation of CT can be identified as the combined effect of both ·OHa and ·OHf, while the degradation of RE was mainly due to the ·OHf. Electron paramagnetic resonance coupled with spin trapping agents was used to detect the relative concentration of hydroxyl radicals in all the photocatalytic degradation processes. After a series analysis, we proposed that the mechanism of selective degradation mainly depends on the concentration of ·OHf for the pollutant molecules with weak adsorption on the catalyst surface.

Abstract:
Background Patients are using online health forums (OHFs) to exchange about their health, diseases and treatments. Some OHFs are independent, not submitted to health care providers’ control nor to social desirability. This must probably influence the very nature of patient’s learning. Objectives: This research aims to bring some answers to the following questions: What are the characteristics of independent OHFs? What are OHF internaut patients’ profile? How do they use OHFs? Are there any characteristics that might help to understand their use of OHFs? Methods: A literature review has been undertaken querying 10 databases. The review was completed with an analysis of the “grey literature”. Eleven keywords were used singly or in combination. The article selection was conducted by two independent researchers. Results: 23 documents were selected and analysed. Five OHF definitions, three user’s classifications and four OHF uses were identified and analysed. Discussion: The review allowed us to 1) formulate a definition of a chronic health conditions oriented OHF, 2) describe its characteristics, 3) suggest a users’ classification and, 4) describe the four OHF uses. Conclusions: Independent OHF is a virtual and free space beyond institutional control. It may be considered as a learning and educational media, formal and informal, and spontaneous. The understanding of the knowledge acquisition processes and strategies among OHF users is necessary in order to use this web tool as patient education strategy.

Abstract:
AbstractA coupled atmosphere-sea-ice model is used to study the sensitivity of the Antarctic sea-ice distribution to oceanic heat flux (OHF). Remote sensing of sea ice from microwave radiometers provides data on ice extent and ice concentration. The ice-thickness data used are from ship-based observations. Our simulations suggest that OHF values of 0−5 W m−2 will cause sea ice to be too thick in the model. A value of 20−25 Wm−2 throughout the year causes sea ice to be too thin in the model. The model results indicate that a seasonally varying OHF is required to match the modelled thickness with observations. Values of 5−30 Wm with an annual mean of 10−15 Wm−2, give a reasonable distribution of sea-ice thickness. This agrees with the limited observations of OHF available for the Antarctic. The model results also indicate that the OHF should be varied spatially. When a seasonally and spatially variable OHF is applied to the coupled atmosphere-sea-ice model a still better simulation of the sea-ice distribution is obtained. Our results also suggest that the role of ice advection is very important in the determination of the sea-ice distribution, and it can be quantified by the model.

Abstract:
Epidemiological and animal studies suggest that diet-induced epigenetic modifications in early life can contribute to development of the metabolic syndrome in adulthood. We previously reported features of the metabolic syndrome in adult offspring of rats fed a diet rich in animal fat during pregnancy and suckling. We now report a study to compare the relative effects of high-fat feeding during 1) pregnancy and 2) the suckling period in the development of these disorders. As observed previously, 6-mo-old female offspring of fat-fed dams suckled by the same fat-fed dams (OHF) demonstrated raised blood pressure, despite being fed a balanced diet from weaning. Female offspring of fat-fed dams “cross fostered” to dams consuming a control diet during suckling (OHF/C) demonstrated raised blood pressure compared with controls (OC) [systolic blood pressure (SBP; mmHg) means ± SE: OHF/C, 132.5 ± 3.0, n = 6 vs. OC, 119.0 ± 3.8, n = 7, P < 0.05]. Female offspring of controls cross fostered to dams consuming the fat diet (OC/HF) were also hypertensive [SBP (mmHg) 131.0 ± 2.5 mmHg, n = 6 vs. OC, P < 0.05]. Endothelium-dependent relaxation (EDR) of male and female OHF and OHF/C mesenteric small arteries was similar and blunted compared with OC ( P < 0.001). OC/HF arteries showed profoundly impaired EDR (OC/HF vs. OHF, P < 0.001). OHF/C and OC/HF demonstrated hyperinsulinemia and increased adiposity. Features of the metabolic syndrome in adult offspring of fat-fed rats can be acquired both antenatally and during suckling. However, exposure during pregnancy confers adaptive protection against endothelial dysfunction induced by maternal fat feeding during suckling.

Abstract:
PURPOSE: There is no simple and practical method for the estimation of the interpatient variability of cytochrome P450 (CYP3A4) enzyme activity. Cortisol is metabolized by this enzyme and excreted as 6-beta-hydroxycortisol (6β-OHF) and free-cortisol (FC) in urine, and docetaxel is also metabolized by hepatic CYP3A4 enzyme. We developed a new method for the estimation of CYP3A4 activity by measuring urinary cortisol metabolite after administration of exogenous cortisol. This study was aimed at assessing the predictability of the individual activity of CYP3A4 estimated by this method. PATIENTS AND METHODS: Thirty patients with advanced non–small-cell lung cancer were entered onto this study. Hydrocortisone 300 mg was administered intravenously, and urinary 6β-OHF and FC were measured. More than 2 days later, 60 mg/m2 of docetaxel was administered intravenously with pharmacokinetic sampling. The correlation between docetaxel pharmacokinetics and estimated interpatient variability of CYP3A4 activity with the application of our method was assessed. RESULTS: After cortisol administration, the total amount of 24-hour urinary 6β-OHF (T6β-OHF) increased about 60-fold compared with pretreatment levels, averaging 12,273 ± 4,076 μg/d (mean ± SD). Docetaxel clearance (CL) and area under the concentration-time curve averaged 24.5 ± 6.4 L/h/m2 and 2.66 ± 0.91 mg/L 8729· h, respectively. An excellent correlation between docetaxel CL and T6β-OHF was observed (r = .867). In multivariate analysis, T6β-OHF (P < .001), alpha-1-acid glycoprotein (P < .004), AST (P = .007), and age (P = .022) significantly correlated with docetaxel CL. CONCLUSION: The interpatient variability of CYP3A4 activity and docetaxel CL could be predicted by measuring T6β-OHF after cortisol administration.

Abstract:
We previously reported that prenatal and suckling exposure to a maternal diet rich in animal fat leads to cardiovascular dysfunction in young adult rat offspring with subsequent development of dyslipidemia and hyperglycemia. We have further investigated glucose homeostasis in adult female offspring by euglycemic-hyperinsulinemic clamp and by dynamic assessment of glucose-stimulated insulin secretion in isolated, perifused pancreatic islet cells. Additionally, given the link between reduced mitochondrial DNA (mtDNA) content and the development of type 2 diabetes mellitus, we have measured mtDNA in organs from young adult animals. Sprague-Dawley rats were fed a diet rich in animal fat or normal chow throughout pregnancy and weaning. Infusion of insulin (5 mU·kg−1·min−1) resulted in a higher steady-state plasma insulin concentration in 1-year-old offspring of fat-fed dams (OHF, n = 4) vs. offspring of control dams (OC, n = 4, P < 0.01). Glucose-stimulated insulin secretion in isolated islets from 9-mo-old OHF was significantly reduced compared with OC ( n = 4, P < 0.05). Transmission electron micrography showed altered insulin secretory granule morphology in OHF pancreatic β-cells. Kidney mtDNA was reduced in 3-mo-old OHF [16S-to-18S gene ratio: OC ( n = 10) 1.05 ± 0.19 vs. OHF ( n = 10) 0.66 ± 0.06, P < 0.05]. At 6 mo, gene chip microarray of OHF aorta showed reduced expression of the mitochondrial genome. Prenatal and suckling exposure to a diet rich in animal fat leads to whole body insulin resistance and pancreatic β-cell dysfunction in adulthood, which is preceded by reduced tissue mtDNA content and altered mitochondrial gene expression.

Abstract We modified our previous enzyme immunoassay (Clin Chim Acta 1986;157:267-76) for estimating 6 beta-hydroxycortisol (6 beta-OHF) to provide a more routine procedure for measuring it in urine and to increase sensitivity for its measurement in serum. Precision, analytical recovery, specificity, and detection limit are reported. 6 beta-OHF and 17-hydroxycorticosteroids in 24-h and 4-h (08:00-12:00 h) urine collections from healthy volunteers showed no significant day-to-day differences in excretion rate for either collection period. Mean values for 6 beta-OHF in serum of men, women, and women taking oral contraceptives showed no significant differences among these groups.

Abstract:
Background: The South African National Defence Force (SANDF) like other Defence Forces of the world, conducts medical classification on their members. This medical classification has, as one of the components, an Oral Health Fitness (OHF) classification which is done according to North Atlantic Treaty Organisation (NATO) standards. The aim of the Oral Health Fitness classification is to standardize dental readiness, assess oral health, prioritize dental care, minimize the number of dental emergencies (DE), and emphasize the importance of good oral health to all active duty and reserve forces. Medical classification is conducted by the South African Military Health Services (SAMHS). Aim: The aim of the study was to evaluate the dental emergency outcomes of the Oral Health Fitness classification of the SAMHS in Area Military Health Unit Gauteng (AMHU GT), South Africa Objectives: To determine dental emergency rate for the SAMHS, analyse the dental emergencies and to make recommendations regarding dental emergencies to the SAMHS Methods: A cross-sectional retrospective record analyses of members of the SANDF that received an OHF classification of 1 and 2 in AMHU GT in 2009. The AMHU GT members were followed up for a year to determine if they developed dental emergencies. Data analysis included frequency tables, chi-square tests and logistic regression analysis. The level of significance was set at p<0.05. Results: The dental emergency rate for AMHU Gauteng was 307/1000 per year. The type of dental emergencies were: 58.5% dental restorations, 13% extractions and related complications, 4.3% crown and bridge, 3.9% emergency root canals, 9.9% recementations, 3.6% denture related problems while other emergencies were 6.8%. Patients were more likely to experience a dental emergency if they were white, female, of OHF 2 classification and older than fifty years of age. Conversely they were least likely to experience a dental emergency if they were black, male, of OHF 1 classification and in the age group 31-40. Conclusion: The dental emergency rate of 307/1000 per year for the SANDF is high compared to military health units from other countries and it was influenced by race, age and gender. The types of dental emergencies were mainly preventable.

Abstract:
Ce travail a pour objectif de développer des biocomposites à base de poly(3-hydroxybutyrate-co-3-hydroxyvalérate) (PHBV) et de farine grignons d'olive (FGO) préparés par mélange fondu. Il s'articule autour de quatre parties. La première partie comprend une étude de la morphologie et des propriétés physiques des échantillons biocomposites PHBV/FGO aux taux de charge de 10, 20 et 30% en masse. Les résultats indiquent que le système PHBV/FGO se caractérise par une séparation de phase dont le nombre et la taille des particules de FGO augmentent avec le taux de charge. De plus, la stabilité thermique et les propriétés barrières vis à vis de la vapeur d'eau et de l'oxygène ont diminué. Par contre, l'incorporation de la FGO dans le PHBV induit une augmentation du module d'Young qui s'accentue avec le taux de charge. La même tendance est également observée avec le module de conservation déterminé par DMA. Dans la seconde partie, l'impact du PHBV-g-MA comme agent compatibilisant dans les biocomposites PHBV/FGO a été évalué en fonction du taux de charge. La caractérisation morphologique du système ternaire a révélé que la présence du PHBV-g-MA dans les biocomposites PHBV/FGO induit une meilleure adhésion interfaciale entre les particules de la FGO et la matrice PHBV en raison des interactions charge-matrice. En conséquence, une nette amélioration des propriétés mécaniques, viscoélastiques et barrières aux gaz (vapeur d'eau et oxygène) est observée. Dans la troisième partie, une modification chimique de la FGO avec le trimethoxy (octadecyl)-silane (TMOS) et son influence sur la morphologie et les propriétés physiques de biocomposites PHBV/FGO: 80/20 ont été étudiées. Les résultats révèlent une dispersion fine et homogène de la FGO traitée au TMOS dans la matrice PHBV avec en apparence moins de microvides en comparaison avec le biocomposite non modifié. Les propriétés physico-mécaniques du biocomposite PHBV/FGO modifiée sont sensiblement améliorées. La dernière partie consacrée à une étude du vieillissement hygrothermique dans l'eau de mer à 25 et 40°C de films de biocomposites PHBV/FGO: 80/20 avant et après modification, révèle que la FGO favorise la cinétique de dégradation du système PHBV/FGO indépendamment du traitement. Toutefois, le biocomposite PHBV/FGO traité avec des organo-silanes se caractérise relativement par une résistance à la dégradation hygrothermique à 25 et 40°C par rapport au reste des échantillons biocomposites
This work aims to develop a biocomposites based on poly(3-hydroxybutyrate-co-3-hydroxyvalérate) (PHBV) and olive husk flour (OHF) prepared by melt compounding. It's articulated around four parts. The first part includes a study of the morphology and physical properties of the PHBV/OHF biocomposite samples at the loading rates of 10, 20 and 30 wt%. The results indicate that the PHBV/OHF system is characterized by a phase separation whose number and size of OHF particles increases with the loading rate. Moreover, the thermal stability and the barrier properties against water vapor and oxygen have decreased. On the other hand, the incorporation of the OHF in the PHBV matrix induces an increase in the Young's modulus which is accentuated with filler content. The same trend is also observed with the storage modulus determined by DMA. In the second part, the effects of PHBV-g-MA used as the compatibilizer for PHBV/OHF biocomposites were evaluated as a function of the loading rate. The morphological characterization of the ternary system revealed that the presence of PHBV-g-MA in the PHBV/OHF biocomposites induces better interfacial adhesion between the OHF particles and the PHBV matrix due to filler-matrix interactions. Consequently, a significant improvement in the mechanical, viscoelastic and gas barrier properties (water vapor and oxygen) is observed. In the third part, a chemical modification of OHF with trimethoxy(octadecyl)-silane (TMOS) and its influence on the morphology and physical properties of PHBV/OHF: 80/20 biocomposites was studied. The results reveal a fine and homogeneous dispersion of the TMOS-treated OHF in the PHBV matrix with apparently fewer microvides compared to the unmodified biocomposite. The physical and mechanical properties of the modified PHBV/OHF biocomposite are significantly improved. The last part devoted to a study of the hygrothermal aging in sea water at 25 and 40°C of films of biocomposites PHBV/OHF: 80/20 before and after modification reveals that the OHF promotes the degradation kinetics of the PHBV/OHF system regardless of treatment. However, the organo-silane-treated PHBV/OHF biocomposite is relatively characterized by a resistance to hygrothermal degradation at 25 and 40°C compared to the rest of the biocomposite samples

Abstract:
Oligosaccharides and polysaccharides have different effects on the morphology and production of secondary metabolites by Penicillium chrysogenum P2 (ATCC 48271). Addition Of oligosaccharides, derived from sodium alginate and locust bean gum, to submerged cultures of P. chrysogenum P2, at milligram per litre concentration (150 mgL-1), increased secondary metabolite levels and spore production, caused changes in morphology and gerRiination of spores, and affected the production of Reactive Oxygen Species. The source of the oligosaccharides controlled their effects on the cultures. Oligosaccharides when added to submerged cultures of P. chrysogenum P2 increased both penicillin G and extracellular levels of 6-aminopenicillanic acid concentrations. The oligosaccharides had no significant effects on biomass levels. Locust bean gum-derived oligosaccharides (mannan oligosaccharides, DP 5-8), showed the highest levels of enhancement in both penicillin G and 6-aminopenicillanic acid concentrations. Sodium alginate-derived oligosaccharides, (oligoguluronate, DP 7 and oligomannuronate, DP 7), also induced elicitation of penicillin G and 6-aminopenicillanic acid. Oligomannuronate was shown to be more effective than oligoguluronate. In P. chrysogenum P2 cultures mannan, oligomannuronate and oligoguluronate oligosaccharides enhanced yields of penicillin G by 101%, 78% and 59%, respectively. Addition of mannan, oligomannuronate and oligoguluronate oligosaccharides enhanced the levels of 6- aminopenicillanic acid by 39%, 26% and 19%, respectively. The addition of oligosaccharides and polysaccharides to spores of P. chrysogenum P2 in liquid medium had varying (inhibitory or stimulatory) effects on germination, germ-tube and clump development. The addition of oligosaccharides to submerged cultures of P. chrysogenum P2 showed effects on clump size and hyphal tip numbers. Mannan oligosaccharides had the greatest effect on morphology followed by oligomannuronate and oligoguluronate oligosaccharides. Oligosaccharides also speeded-up the sporulation and increased the concentration of spores of P. chrysogenum P2 in liquid cultures. Mannan oligosaccharides had the greatest effect followed by oligomannuronate and oligoguluronate oligosaccharides. 8-aminonaphthalene-1,3,6-trisulphonate-tagged oligosaccharide studies showed that the oligosaccharides pass through the cell wall of P. chrysogenum P2 suggesting a possible mechanism through modulation of gene function. The elicitation pattern was shown to be similar to untagged oligosaccharides. Oligosaccharides and polysaccharides were shown to inhibit production of Reactive Oxygen Species in P. chrysogenum P2. The highest level of inhibition was elicited by mannan followed by oligornannuronate and oligoguluronate oligosaccharides, and then locust bean gum and alginate. The results of the study showed the potential of oligosaccharides as elicitors of secondary metabolites in P. chrysogenum P2 as a filamentous fungus model. Understanding the elicitation mechanism could provide routes for ftirther exploitation of the potential of filamentous fungi in production of commercial products.

Abstract:
Wave scattering from periodic arrays is ubiquitous in applied mathematics, and has received a great deal of attention over the past century, not least due to the physical significance of understanding the reflection and transmission of plane waves from such arrays in the contexts of electromagnetic waves, acoustics, water waves and elasticity. The aim of the thesis is to develop an accurate and efficient numerical method to solve for the reflection and transmission of an acoustic plane wave from arrays of arbitrary shaped obstacles that have an axis of symmetry aligned in a direction perpendicular to the array. We are particularly interested in the difficult case when the characteristic length scale of the scatterers, and the periodic spacing of the array are of the same order of magnitude as the wavelength of the incident wave. It is shown that the boundary value problem for the infinite array can be reduced to an integral equation over a central representative cell containing a single scatterer, which can then be solved using the boundary element method. Particular attention is paid to the convergence of the resulting periodic Green's function. Using established methods to calculate the reflection and transmission coefficients, we develop a new method to increase the rate of convergence of the periodic Green's function in both two and three dimensions.

Abstract:
The conservation management of wild cetaceans depends on knowledge of their population structure and dynamics, and how human activities impact upon resource use and behaviour. The short-finned pilot whale (Globicephala macrorhynchus) is believed to possess a complex social structure, with a high degree of bonding among familial group members that results in natal group philopatry. As the subject of intense tourism activity, the pilot whale population around the Atlantic island of Tenerife was studied to determine spatial distribution, the degree of site fidelity, and the social structure from 2005-2008, using behavioural data and a photo-identification image database consisting of ca. 55,000 photographs compiled by citizen scientists. There were 382 well-marked individuals identified, which varied in the degree of site fidelity from those encountered throughout the study period to those that were only seen once. At least 22 individuals were matched to a previous study, demonstrating residency spanning 19 years. The distribution of whales in the study area was not random or uniform, and higher rates of encounter occurred offshore at depths of 800-2100 m. The area is important for breeding, calving and foraging, with a core area measuring 99.1 km2 identified. Social analyses, based on the associations of photo-identified individuals, suggested that the study area contains groups of animals with long-term, constant relationships, with 11 longitudinally stable social clusters identified using hierarchical cluster analysis. However a large proportion of the population forms short-term bonds or has no apparent affiliation with other conspecifics. Future studies should focus on increasing the extent of study area as the full ranging behaviour of the pilot whales may not have been encompassed here. The long-term site fidelity and stable relationships demonstrated in this island-associated population, may need to be more closely monitored, given the increasing concerns about anthropogenic disturbance in the Canary Islands.

Abstract:
Parental bereavement has widely been considered, in the context of child development and well being, to be one of the most traumatic events that can occur in childhood. Parental bereavement through substance misuse is a previously unresearched aspect of bereavement research, and a previously unresearched aspect of ‘hidden harm.’ This qualitative research looks at the lived experiences of four girls who have been parentally bereaved through substance misuse, using interpretative phenomenological analysis (IPA). IPA serves the dual purposes of ‘giving voice’ to these previously unheard voices, and interpreting their experience of dealing with bereavements, through the lens of psychological theory and the wider canon of bereavement research. The information for the analysis was collected in individual meetings with each of the girls, gathered through semi structured interviews which took place over one to four meetings. Life for all the girls was difficult and complicated as a consequence of their parents’ troubled lives, and for all the girls their lives were marked by multiple losses and adverse childhood events both before and after their mother’s or father’s death. The analysis tries to capture the children’s narratives about their lives as a journey in which one girl is managing to stay ‘on track’, whilst the others have gone ‘off the rails.’ None of the girls had made a deliberate choice to be ‘off the rails’, yet the environment in which they live meant their life journey is a stormy one, with no safe haven, and their lives have not offered them the ‘lifelines’ they needed in order to stay ‘on track’, and navigate their way through this traumatic event. They feel shame for their disruptive manifestations of grief, for the ways in which they ‘cope ugly.’ They now have ‘spoiled identities’, and are struggling to achieve a sense of self that will help them to make the transition to adulthood. The experience of the fourth girl demonstrates the ways in which she works to achieve her personal identity, preserve her ‘reputation’, and the secure attachment she needed, in order to police her potentially disruptive manifestations of grief. In the context of this research ‘on track’ or ‘off the rails’ are positioned as more helpful constructs than ‘normal’ and ‘complicated’ grief. The findings of this small scale research demonstrate the risks and inaccuracies in accepting the conclusion of large scale research studies which seem to indicate parental bereavement is not a risk factor for child wellbeing when family variables are taken in to account. Instead it demonstrates the ways in which dealing with parental bereavement, especially when compounded by other complex life events and insecure attachments, can result in children being positioned as ‘bad’ rather than ‘sad’ as villains rather than victims, children for whom their troubled lives and loss offer ‘no excuse’ for their troubled grieving. More research is needed to understand more about the lives and experiences of this vulnerable sub group of parentally bereaved children.

Abstract:
This paper presents results of both analytical predictions and towing basin validation experiments for the basic resistance characteristics of a new small waterplane area, tri hull ship concept termed the Wave Cancellation Multihull (WCM). This is a variant of the O'Neill Hull form (OHF) type arrangement but which exploits extensive wave cancellation effects between the various hull elements: the center body, the center strut, and the two outer hulls. Significant reductions in total ship wave making resistance have been predicted in a high speed range normally associated only with fine form monohull ships. A tapered-strut-type center body shape bas been developed as an alternative to the original OHF center body and-strut configuration. Towing basin tests confirm the predictions of the thin ship theory wave making resistance variations. The resulting complete ship wavemaking resistance can be reduced to such an extent that the total resistance of a WCM ship geometry is comparable to that of a monohull at high ship speeds, despite the substantially larger wetted surface area. Summary comparison plots are presented for BHP/Displacement versus speed for several 4300 LT ship forms, including a candidate WCM arrangement.These show, for example, that at 30 knots it is possible to achieve a 28% reduction of effective horsepower with a realistic WCM configuration compared with the SWATH VII performance (best performing SWATH to date). It is also shown that the candidate WCM form bas about the same effective horsepower as a slim combatant monohull form at the speed in the neighborhood of 30-32 knots, despite 88% more wetted surface area.
