Are organ donation communication decisions reasoned or reactive? A test of the utility of an augmented theory of planned behaviour with the prototype/willingness model
Authors: Hyde Melissa K. , White Katherine M. 
Published: September 2009

Objectives. To explore whether people's organ donation consent decisions occur via a reasoned and/or social reaction pathway.Design. We examined prospectively students' and community members' decisions to register consent on a donor register and discuss organ donation wishes with family.Method. Participants completed items assessing theory of planned behaviour (TPB; attitude, subjective norm, perceived behavioural control (PBC)), prototype/willingness model (PWM; donor prototype favourability/similarity, past behaviour), and proposed additional influences (moral norm, self‐identity, recipient prototypes) for registering (N =339) and discussing (N =315) intentions/willingness. Participants self‐reported their registering (N =177) and discussing (N =166) behaviour 1 month later. The utility of the (1) TPB, (2) PWM, (3) augmented TPB with PWM, and (4) augmented TPB with PWM and extensions was tested using structural equation modelling for registering and discussing intentions/willingness, and logistic regression for behaviour.Results. While the TPB proved a more parsimonious model, fit indices suggested that the other proposed models offered viable options, explaining greater variance in communication intentions/willingness. The TPB, augmented TPB with PWM, and extended augmented TPB with PWM best explained registering and discussing decisions. The proposed and revised PWM also proved an adequate fit for discussing decisions. Respondents with stronger intentions (and PBC for registering) had a higher likelihood of registering and discussing.Conclusions. People's decisions to communicate donation wishes may be better explained via a reasoned pathway (especially for registering); however, discussing involves more reactive elements. The role of moral norm, self‐identity, and prototypes as influences predicting communication decisions were highlighted also.
A New Testing Method to Evaluate the Relative Drying Performance of Different Building Envelope Systems Using Water Trays in Stud Cavities as Moisture Source
Authors: Fazio Paul , Alturkistani Arslan , Rao Jiwu , Mao Qian 
Published: September 2009

Abstract
Due to defects in construction, design, and/or deterioration during operation, failure occurs where rain water penetrates into stud cavities of wall systems. Some wall systems tolerate this water intrusion better than others. A new test method has been developed to evaluate the relative capacities of different wall systems to dry out the invading water. In the test setup, the walls of a two-story test hut were made up of 31 wall assemblies (each 2.44×0.76 m2) of different configurations. The hut was erected within a large climatic chamber and subjected to a steady-state climatic loading for 288 days. Within each stud cavity, a water tray on an electronic load cell was placed on the bottom plate to provide a moisture source that represents water penetrating into the stud cavity and provides a consistent moisture loading from one specimen to another. Each wall assembly was instrumented with 25 gravimetric samples and relative humidity and temperature sensors/probes. Indexes were developed to indicate the relative performance of the walls.
Surface and grain-boundary segregation studied by quantitative AES and XPS
Authors: Hofmann Siegfried , Lejček Pavel 
Published: September 2009

Abstract
Applied surface and interface analysis methods such as Auger electron spectroscopy and X-ray photoelectron spectroscopy are particularly well suited to studying intergranular segregation. In the case of internal interfaces such as grain boundaries, they must be transformed into two open surfaces by intergranular fracture. The main task is quantification of the measured spectra. Advantages and disadvantages of different approaches are discussed. It is shown that only for very low segregation levels do the simple and modified ratio methods give acceptable results. With increasing amount of enrichment, the more complicated methods with full description of the contribution of the first few monolayers to the total measured intensity have to be applied in order to obtain reliable concentration values that are useful for the determination of the concentration- and temperature-independent standard enthalpy and entropy of segregation.
Pierre Auger – Lise Meitner: Comparative contributions to the Auger effect
Authors: Hardouin Duparc Olivier 
Published: September 2009

Abstract
It has been claimed by R. Sietmann that the attribution of the discovery of the so-called ‘Auger’ effect to Pierre Auger was a false attribution and that Lise Meitner should have got the credit for that discovery. However Sietmann himself recognised that Meitner's description of this effect was ‘buried in’ two larger papers whose primary concern was nuclear physics. Sietmann only mentioned Auger's 1925 article and did not mention his 1923 article, an omission now found in many places. We examine again L. Meitner's and P. Auger's contributions to the description of the ‘Auger’ effect. Meitner's concern was the exact nature of the (nuclear) beta radiations about which she opposed Ch. D. Ellis, and this had been the subject of an intense Berlin–Cambridge controversy where Ellis' description eventually prevailed. Auger's observations were the central theme of his PhD thesis at the J. Perrin's laboratory on the composed photoelectric effect. We thus believe that while L. Meitner should have shared the Nobel Prize with O. Hahn, the Auger effect has rightly been attributed to Auger.
The effect of electro-thermal fatigue on the structure of power electronic devices. Micro-structural evolution of the metallization layer
Authors: Khong Benjamin , Legros Marc , Dupuy Philippe , Levade Colette , Vanderschaeve Guy 
Published: September 2009

Abstract
The fatigue-induced modifications of the structure of power devices on components that underwent extreme electro-thermal fatigue were investigated, with special attention to the behaviour of the Al metallization layer. Electrical cycling induced a moderate grain growth in the metallization layer, except for the regions located beneath the connection wires. There the wire bonding process is associated with severe plastic deformation, leading to a fragmentation of the initial grains and significant grain growth. Grain-boundary grooving is another example of fatigue-induced structural changes: it reveals an intense stress- and temperature-driven grain boundary diffusion process.
f-Element hydrides: structure and magnetism
Authors: Havela Ladislav , Miliyanchuk Khrystyna , Kolomiets Alexandre 
Published: September 2009

Abstract
Systematic magnetic and specific-heat studies of hydrides of ternary compounds on the basis of rare earths or actinides help to unravel different roles of f-states in these two classes of materials. In rare earths, H absorption tends to suppress magnetism by weakening the exchange interaction mediated by conduction electrons. Light actinides exhibit a 5f band of variable width at the Fermi level and the hydrogenation makes magnetic features typically stronger. 5f band narrowing due to volume expansion is responsible for this net tendency, but the effects of H bonding cannot be neglected.

A strong correlation between the structural, magnetic, electro-physical and optical properties of the samples gives evidence that the samples consist of a distribution of ferromagnetic and paramagnetic regions. Such a phase separation can be understood by a non-random distribution of the local magnetic moments and fluctuations of the exchange interaction in the samples having semiconductor-type conductivity.

Published: September 2009

Abstract
Superlattices of 15 periods of (GaSb/Mn) with bilayer periods of 3 nm and 10 nm were grown on a GaAs(001) substrate by laser ablation and studied by X-ray glancing-incidence reflectometry. Both qualitative analysis and quantitative treatment of the X-ray reflection curves allow us to restore the depth profiles of the core electron density into the samples studied and to estimate the diffusion depth of Mn atoms into adjacent thicker GaSb layers, which appeared to be 3.5 nm thick.

Abstract
Antiferromagnetic order at TN = 21 K was discovered in the intermetallic compound HoZn5Al3, which crystallizes in its own structure type. A metamagnetic transition can be induced by magnetic fields of 4 T. Enormous values of specific heat below 1 K are attributed to the Ho nuclear specific heat.

)2 with x = 0.05, 0.10, 0.15, 0.20, 0.25, and 0.30. The substitution of Co by Rh leads to a decrease in the critical temperature with increasing rhodium content from Tc = 350 K for x = 0.05 to T
c = 200 K for x = 0.30. The maximum entropy change slowly increases with increasing Rh concentration and reaches about 1 J K– 1 kg– 1 for x = 0.30 and a field change of 1 T. The second studied system was Dy(Fe

Co1 – x
)2 with x = 0.00, 0.01, and 0.03. The critical temperature as well as the magnetic entropy change strongly depends on the Fe concentration. The transition temperature increases from 140 K in DyCo2 to 210 K for 3 % Fe but the maximum of the entropy change quickly decreases from 5 to 1.2 J K–1 kg– 1 for field of 1 T.
Thickness shear modes and magnetoelastic waves in a bi-layered structure: magnetic film–non-magnetic substrate
Authors: Gareeva Zukhra , Doroshenko Rurik 
Published: September 2009

Abstract
Thickness modes of magnetoelastic waves in a bi-layered structure magnetic–non-magnetic material have been theoretically investigated. Plots illustrating the dependence of harmonics of resonant frequencies upon the magnetic layer thickness were constructed at various magnetoelastic wave vectors. A dependence of the dimensional resonance frequencies on the wave number of magnetoelastic waves propagating along the saturating field direction is found. Peculiarities of the resonant frequency harmonics behavior with varying magnetic layer thickness and number are analyzed. The multimode character of the thickness magnetoelastic resonances, attributed to the possibility of excitation of magnetoelastic waves with different wave number is discussed.

Abstract
Doping the Bi2212 phase by Pb usually results in an enhancement of the pinning properties and the T
c. Using elements other than Bi and/or other sites one may obtain opposite results. In this work we present the effect on structural and magnetic properties of Bi2212 superconducting ceramics when co-doping with La and Pb is used. Bi1.4Pb0.6Sr2Ca1–x

Cu2O8+δ (0 ≤ x ≤ 0.025) superconducting ceramic samples were prepared using a solid-state reaction method. Structural and magnetic characterizations were made by means of X-ray diffraction, scanning electron microscopy and AC susceptibility measurements. The obtained crystalline structure is mainly tetragonal with a c-axis lattice parameter decreasing with La content. Substitution by La reduces the fraction content of the parasitic phase Bi2201 and the size of the grains. The transition temperature Tc is enhanced quasi linearly with the La content and the superconducting volume fraction has a maximum for x = 0.01.

Published: September 2009

Abstract
The effect of hydrogenation on magnetic properties of the weakly ferromagnetic superconductor UCoGe was studied. UCoGe hydrides were synthesized at T = 773 K at different pressure of H2 gas (8, 5, 2 bar). The hydrogenation at 8 bar and 5 bar results in a change of the crystal structure from orthorhombic (TiNiSi structure type) to hexagonal (ZrBeSi type) with H concentrations just below 2 H/f. u. For one of such β-hydrides, UCoGeH1.7, the Curie temperature increases from 3 K up to 50 K and the spontaneous magnetic moment from 0.03 μB/f. u. to 0.05 μB/f. u. An α-hydride of UCoGe (ΔV/V = 0.25 %) with a hydrogen concentration 0.1 H/f. u. was obtained at 2 bar. It has the same crystal structure as a pure compound and surprisingly exhibits no magnetic order.

Published: September 2009

Abstract
Nanolayers were deposited onto surfaces of n-type InP single crystal wafers by electrophoresis from reverse micelle colloid solutions containing palladium nanoparticles. Two types of nanolayers were deposited, by applying a positive potential or a negative potential on the InP wafer. Further, wafers with nanolayers were annealed in high vacuum at 400 °C. The nanolayers were studied using capacitance–voltage characteristics on a mercury probe, by atomic force microscopy and by secondary-ion mass spectroscopy. Two types of Schottky-like diodes were prepared on wafers with the two types of nanolayers and studied by current–voltage characteristics. The diodes with nanolayers deposited by applying the positive potential, which contained Pd nanolayers, showed characteristics with better rectifying properties than the other type of diodes. Correlations among measured characterizations were found.
Low-temperature specific heat of selected ceramics

Published: September 2009

Abstract
Here we present an analysis of the low-temperature specific heat of selected nitrides (Cr3GaN, GaN, and InN) and niobates (CaNb2O6, Ca2Nb2O7, and Sr2Nb2O7). The low-temperature specific heat is considered as a sum of electronic and phonon contributions, where the electronic part is almost negligible. The phonon specific heat is then described using an additive combination of the Debye and Einstein approaches for acoustic and optical phonons, respectively, together with the correction for the anharmonicity of the phonon spectrum.

Published: September 2009

Abstract
Frequency and temperature dependences of the impedance components have been investigated in darkness and under illumination for PbTe(In) nanocrystalline films. Synthesis of the films was performed using evaporation of a target source to a cooled glass substrate. The films have a column-like structure with a mean grain size varying from about 60 nm to 170 nm depending on the deposition temperature. Analysis of the data obtained revealed that the conductivity of the films is determined by two mechanisms: charge transport along the inversion channels at the grain surface and activation through barriers at the grain boundary. Persistent photoconductivity appears in the films below T = 150 K. The frequency dependence of the relative photoresponse has a pronounced maximum. The photoresponse in the ac mode may be higher by two orders of magnitude than in the dc measurements.

Authors: Siddique MAB , Rahman MK , Hannan ABMA 
Published: September 2009

Abdominal injury is an important aspect of trauma because of difficulty in diagnosis and its lethal potential if not properly treated. Fifty cases of abdominal injury admitted in the surgical wards of Rajshahi Medical College Hospital over 2 years have been studied here. All the patients underwent laparotomy for their management. The age range of the patient was 14 to 70 years and most commonly involved age group was 21 to 30 years. Male to female ratio was 15.6:1. The incidence of penetrating injury predominated (64%) over non-penetrating injury and majority had stab injuries. Road traffic accident predominated in blunt injury. Small gut injury outnumbered all other injuries in both groups. Abdominal pain was the most frequent symptom. Most of the patient arrived in the hospital within 24 hours. Considering clinical presentations and results of investigations, decision for laparotomy was taken with prior resuscitation. doi: 10.3329/taj.v17i2.3452 TAJ 2004; 17(2): 84-88

Published: September 2009

A cross-sectional study was carried out to determine the birth weight status of the newborn babies born at Dhaka Medical College Hospital as well as to find out the prevalence of low birth weight among them. All the new born babies (202) born at the labour room of Dhaka Medical College Hospital during the specified period were included in the study. Maximum newborn babies (78.71%) had birth weight 2.5Kg or more and 21.29% had low birth weight (<2.5 Kg). It was found that mean weight of newborn babies was 2.73 Kg and standard deviation was ± 0.52 Kg. Among them 93.56% were full term babies. In a developing country like ours, occurrence of low birth weight is still very alarming, although it is preventable. Emphasis on health education to inform all the women during antenatal visit about the consequences of low birth weight and significance of delivering the babies with normal birth weight is recommended. doi: 10.3329/taj.v17i2.3454 TAJ 2004; 17(2): 95-98

Fifty children with Kala-azar {27 male (54%) and 23 female (46%)} aged between 2-12 yrs, were studied retrospectively in the pediatric unit of Rajshahi Medical College Hospital to find out the optimal treatment of Kala-azar in children. Sodium stibogluconate was given intravenously at a dose of 10 mg/kbw/day for 20 days in one group (Group-A), 15 mg/kbw/day for 20 days in another group (Group-B), 10 mg/kbw/day B.D. for 20 days in another group (Group-C), and 20 mg/kg of body wt/day for 40 days is last group (Group-D). The apparent cure rates of all regimens were 100%. Side effects of sodium stibogluconate were mild, however, myocarditis developed on 37th day of treatment in one patient which reversed to normal after discontinuation of the drug. 27 patients (54%) could be followed up to six months after discharge from hospital. Two patients in group-A relapsed and none relapsed from group B, C or D. Follow-up of patients in group B, C and D showed improvement in general condition, increase in body weight, Hb% and regression of the size of the liver and spleen and ultimate rate of cure in B, C, D regimens were 100%. But ultimate cure rate in-group A was 71.4% and the significance of difference between A and other regimens (P<0.10) were statistically significant. Sodium stibogluconate 15mg/kg body weight once daily for 20 days (Group-B) had the best of cure rate with low toxicity and may be recommended for routine treatment of childhood Kala-azar in this country. doi: 10.3329/taj.v17i2.3455 TAJ 2004; 17(2): 99-103

Tension-Type, the Forgotten Headache A Common but under Treated Condition
Authors: Kundu Narayan Chandra , Ahmad Quamruddin 
Published: September 2009

Headache is a universal problem. Of all the types of headache, the commonest is Tension-type Headache. The word 'tension' implies that this type of headache can be attributed entirely to tension or stress, which may make people with this type of headache reluctant to consult a physician. Physicians misperceptions that tension-type headache are mild, benign, self-treatable and occur solely due to stress may further trivialize the problem. Thus this disease is often under-diagnosed and not treated properly. This article describes the disease and its management and is being published to increases awareness of the disease amongst the physicians. doi: 10.3329/taj.v17i2.3462 TAJ 2004; 17(2): 121-128
