Portrait of Helen Hunt Jackson painted by A.F. Harmer in 1885, ca. 1885
No full textPhotograph of a portrait of Helen Hunt Jackson painted by A.F. Harmer in 1885, ca. 1885. She is turned slightly to the right and is visible from the chest up. She is wearing a high collared light-colored ruffled blouse under a dark dress. The portrait is signed with the artist's initials, "A.F.H.". Jackson was the author of the book "Ramona." Possibly painted from sittings in 1880 or 1882
Design metrics for evaluating the propulsive efficiency of future ships
No full textThere is an increasing need for the ship design process to take account of environmental issues such as the emission of greenhouse gases and the likely extension of a carbon dioxide charging mechanism to international shipping. These issues, together with the need for economic viability, provide further incentives to improve the efficiency of propulsion of ships. The main components of powering are firstly reviewed. Individual components and other power saving devices are identified which should contribute to improvements in the overall efficiency of propulsion. Suitable design metrics and procedures, taking into account economic and environmental factors, are recommended for the design of future ships

Un’esperienza didattica in tema di paleonutrizione
No full textThe item arises from an "elective" Paleopathology course suggested for students graduating in Medicine and Surgery at the University of Milan. This course discussed subjects as: molecular paleobiology, tumors and infectious paleopathology, paleonutrition, paleopathological museums and history of medicine. The author dealt with the "paleonutrition" subject. Extremely actual aspects emerged which drew the students' attention
Strategische alliantie voor Esprithuis: Strategische allianties als organisatie- en rechtsvorm van samenwerkingsverbanden in de bouw
No full textSamenwerkingsverbanden binnen de bouw krijgen steeds meer aandacht. De studies naar projectallianties door de faculteit Bouwkunde van de Technische Universiteit Delft zijn daar een voorbeeld van. Door de kennis over projectallianties rijst de vraag of projectoverstijgende alliantie - zogenaamde strategische allianties - bruikbare samenwerkingsverbanden kunnen zijn voor ondernemingen in de bouw. Vereniging EspritHuis is een bedrijvenvereniging die op basis van mass customization woningen wil gaan bouwen. Mass customization vraagt van de aanbiedende partij(en) een vergaande uitwisseling van informatie over de verschillende producten die worden aangeboden. De klant krijgt in een mass customized project namelijk de vrijheid om - binnen de (ruime) grenzen van de aanbieder - zijn of haar woonwensen te realiseren. De ontwikkelingen die door Vereniging EspritHuis zijn getieerd vragen van de deelnemers aan de ontwikkeling een intensieve en langdurige samenwerking. De doelen van het ontwikkelingsproces van Vereniging EspritHuis heeft sterke parallellen met de algemene eigenschappen van een strategische alliantie. De probleemstelling van dit rapport is daarom als volgt. Gezien de eerder geschetste situatie is het waardevol de strategische alliantie als organisatie- en contractmodel te onderzoeken en te beschouwen of deze is toe te passen op procesgroep EspritHuis, die op basis van mass customization een nieuw bouwproduct op de markt wil zetten. Vanuit het huidige organisatiemodel van EspritHuis is - om alle deelnemers aan de ontwikkeling te laten wennen aan de verhoudingen binnen een strategische alliantie - een stappenplan opgesteld voor de groei naar een model wat past binnen strategische allianties. Daarnaast is op basis van de nieuwe wetgeving voor personenvennootschappen een keuzeschema opgesteld om de juiste rechtsvorm te kiezen voor de strategische alliantie. Vanuit de mededingingswetgeving is niet te verwachten dat EspritHuis beperkingen zal worden opgelegd.Architectur
Natural organic matter (NOM) fouling characteristics during water treatment with a submerged ultrafiltration membrane reactor: a case study / A. W. Zularisam, A.F. Ismail and M.R. Salim
No full textNatural organic mailer (NOM) has been claimed as the major membrane foulant in drinking water treatment processes. However, the primary fraction of NOM which is believed to cause membrane fouling and significant influence of rejection mechanisms are still unclear and not yet well-established. The main objective of this study is to evaluate the effect of fractionated NOM and their fouling potentials on the submerged ultrafiltration membrane reactor performance. The membrane fouling characteristics of NOM based on hydraulic resistances (Rcp Rg R R) rejection of UV 254nm. DOC, and flux decline were assessed using 68 kDa MWCO hydrophobic polysulfone (PS) and 50 kDa MWCO hydrophilic cellulose acetate (CA) membranes. Both PS and CA membranes were spun by a simple forced convective dry/wet spinning technique. The Sungai Pontian Kecil river water was taken as a sample and was subjected to non-ionic macro-porous ion exchange resins (DAX-8 and XAD-4). The sample was fractionated into three specific classes which were hydrophilic, transphilic and hydrophilic compounds. Results showed that the low aromatic hydrophilic fraction content of NOM attributed to the worst flux decline despite lesser solute rejection than hydrophobic component. In addition, the PS membrane was surprisingly found to exhibit higher NOM rejection especially for the component with higher SUVA (UV254nm/DOC) despite smaller nominal MWCO posed by the hydrophilic CA membrane. Charge interaction between hydrophobic component and membrane surface plays more important role than steric exclusion mechanism. NOM rejection mechanisms were found to be a function of both membrane type and water characteristics
Author Correction:A cattle graph genome incorporating global breed diversity

Assessment of empirical conversion methods for producing 1-min integration time rainfall rate in Malaysia
No full textThis paper presents assessments of empirical conversion methods in obtaining cumulative distribution function of rainfall rate at 1-minute integration time. From collected measured data in Kuala Lumpur, cumulative distributions of rainfall rate at various integration times were compiled. Four conversion methods were selected in the assessment namely: Segal, Burgueno, Ismail et al and Polynomial. The generated 1- minute statistics using the mentioned four empirical conversion methods are then compared with measured statistics, in order to test its validity. Based on the assessment, it can be suggested that the Ismail et al and Polynomial conversion methods seem to be capable of producing rainfall rate statistics at 1-minute integration time with close approximation to the measured values
