    Notes: A Brassica juncea line carrying an introgression from Moricandia arvensis restored male fertility to two cytoplasmic male-sterile (CMS) B. juncea lines carrying either M. arvensis or Diplotaxis catholica cytoplasm. Genetics of fertility restoration was studied in the F1, F2, F3 and backcross generations of the cross between CMS and fertility-restorer lines. No male-sterile plants were found in F1-F3 generations of the cross between CMS [M. arvensis] B. juncea and the restorer. However, a 1: 1 segregation for male sterility and fertility was observed when the F1 was pollinated with non-restorer pollen from a euplasmic line. These results clearly show that restoration is mono-genic and gametophytic. In CMS lines carrying D. catholica cytoplasm, the restorer conferred male fertility to the F1 and showed 3: 1 and 1: 1 segregations for male fertility and sterility in F2 and BC1 generations, respectively, indicating a monogenic, sporophytic mode of fertility restoration. The results were also supported by pollen stainability in the F1 which was about 65% in M. arvensis-based CMS and 〉90% in D. catholica-based CMS. The above results are discussed in the light of previous molecular studies which showed association between CMS and atpA in both systems.

    Notes: Purpose - Plasma spray coating technologies are capable of depositing a wide range of compositions without significantly heating the substrate. The objective is to characterise plasma sprayed metallic coatings on a Fe-based superalloy. Design/methodology/approach - NiCrAlY, Ni-20Cr, Ni3Al and Stellite-6 metallic coatings were deposited on a Fe-based superalloy (32Ni-21Cr-0.3Al-0.3Ti-1.5Mn-1.0Si-0.1C-Bal Fe) by the shrouded plasma spray process. The coatings were characterised in relation to coating thickness, porosity, microhardness and microstructure. The high temperature oxidation behaviour of the coatings was investigated in brief. The techniques used in the present investigation include metallography, XRD and SEM/EDAX. Findings - All the coatings exhibited a lamellar structure with distinctive boundaries along with the presence of some porosity and oxide inclusions. The microhardness of the coatings was observed to vary with the distance from the coating-substrate interface. The St-6 coating had the maximum microhardness, whereas the lowest hardness was exhibited by the Ni3Al coating. The phases revealed by XRD of the coatings confirmed the formation of solid solutions, whereas EDAX analysis of the as-sprayed coatings confirmed the presence of basic elements of the coating powders. So far as high temperature oxidation behaviour is concerned, all of the coatings followed the parabolic rate law and resulted in the formation of protective oxide scales on the substrate superalloy. Originality/value - The plasma spray process provides the possibility of developing coatings of Ni3Al as well as commercial available NiCrAlY, Ni-20Cr and St-6 powders on Fe-based superalloy Superfer 800H

    Notes: Purpose - To develop a water repellent (WR), rodent repellent (RR) and UV resistant (UVR) formulation for woven nylon tapes to be used in aircraft arrester system. Design/methodology/approach - UVR, WR and RR formulation for woven nylon tapes were prepared using silicone oil as WR, oleoresin (OR) (red chilly extract) and denatonium benzoate (DB) as RRs, carbon black for UV resistance and butyral resin as binder. Findings - Incorporation of silicon oil improved the water repellency of the processed nylon tapes. DB and OR in the formulation protected the tapes from rats. The former showed excellent protection for nylon tapes in the experimental conditions. More than 150 days of protection has been achieved in comparison to 27 days using OR. The presence of carbon black along with silicon oil and DB in the formulation enabled the nylon tapes UVR-WR-RR in a single processing step. The presence of RRs and WRs within the same formulation did not affect each other's performance. Research limitations/implications - OR and DB were used as RR materials and silicone oil as WR material. In addition, some other RR and WR materials could have been evaluated. Practical implications - The formulation imparts UV resistance, water and rodent repellency to the nylon tapes after processing. Originality/value - This type of formulation is novel for processing of nylon tapes to be used in aircraft arrester systems.

    Notes: Summary Thirty-six patients fulfilling the criteria for Reiter's disease were studied (29 men and 7 women; 4:1). The mean age of onset was 23.8 years; in 75% of patients the onet was in the second and third decades. Clinical manifestations included low back pain and stiffness (69%), non specific urethritis (53%), heel pain (44%), radiographic sacroiliitis (42%), conjunctivitis (39%), dysentery and diarrhoea (33%), mucosal ulcerations (17%) kidney disease (14%), anterior uveitis (19%), and keratoderma blennorrhagicum (8%). Peripheral arthritis was mono or oligoarthritis in 58% of patients, mainly affecting the large joints of lower extremities, and it was often asymmetric (mean degree of asymmetry=0.37). HLA-B27 antigen was detected in 83% of 36 patients compared with 5.9% of 118 controls (relative risk 79, corrected Fisher's P=7.719E-18).

    Description / Table of Contents: Riassunto Si espande il formalismo di una pseudofunzione di Green per leghe diluite di metalli nella bandad in una sovracompleta serie di funzioni di base. Gli effetti della bandad sono inclusi attraverso il potenziale di impurità efficace non locale. Questo formalismo porta ad un'espressione esatta per il cambiamento di densità degli stati causato dall'introduzione di un'impurità. Il contributo della bandad alla densità degli stati è calcolato per leghe diluite di rame usando un modello semplice di struttura elettronica dei metalli della bandad. Si è trovato che il contributo della bandad è responsabile delle risonanze e delle autorisonanze nella densità degli stati. Si ottiene uno studio sistematico degli effetti della variazione del potenziale d'impurità, dell'ampiezza di risonanzad e dell'energia della bandad sulla densità degli stati. Il potenziale repulsivo diffonde gli statid verso energie più alte che possono portare a stati legati e virtualmente legati in vicinanza del livello di Fermi, mentre il potenziale di attrazione diffonde gli statid verso energie più basse che possono portare a stati legati e virtualmente legati verso il fondo della banda di conduzione. I risultati prevedono anche che la probabilità di stati legati e virtualmente legati sia più grande per leghe diluite con rame con una bandad stretta.
    Abstract: Резюме Развивается формализм псевдо-гриновских функций для малолеги-рованных сплавовd-зонных металлов.d-зонные эффекты включаются через нело-кальный эффективный потенциал примеси. Предложенный формализм приводит к точному выражению для изменения в плотности состояний, которое обусловлено введением примеси. Вычисляет вкладd-зоны в плотность состояний для малолеги-рованных сплавов меди, используя простую модель для электронной структурыd-зонных металлов. Обнаружено, что вклад,d-зоны ответственен за резонансы и антирезонансы в плотности состояний. Проводится систематическое исследование влияния изменения потенциала примеси, шириныd-резонанса и энергииd-зоны на плотность состояний. Потенциал отталкивания при рассеянии переводитd-состояния в область боляших энергий, что может привести к связанным состояниям и виртуаль-ным связанным состояниям в окрестности уровня Ферми. Потенциал притяжения при рассеянии переводитd-состояния в область меньших энергий, что может привести к связанным состояниям и виртуальным связанным состояниям вблизи дна зоны проводимости. Полученные результаты предсказывают, что вероятность связанного и виртуального связанного состояния окзывается больше для малолег ированного сплава меди с узкойd-зоной.
    Notes: Summary The pseudo Green's function formalism for dilute alloys ofd-band metals is expanded in an overcomplete set of basis functions. Thed-band effects are included through the nonlocal effective impurity potential. The present formalism leads to an exact expression for the change in density of states caused by the introduction of an impurity. Thed-band contribution to the density of states is calculated for dilute copper alloys by using a simple model for the electronic structure of thed-band metals. It is found that thed-band contribution is responsible for the resonances and antiresonances in the density of states. A systematic study of the effects of the variation of impurity potential,d-resonance width andd-band energy on the density of states is carried out. The repulsive potential scatters thed states towards the higher energy which may lead to bound and virtual bound states in the vicinity of the Fermi level, while the attractive potential scatters thed states towards the lower energy which may lead to bound and virtual bound states towards the bottom of the conduction band. The results also predict that the probability of a bound and a virtual bound state is higher for dilute alloys of copper with a narrowd-band.
