    Notes: Abstract In this paper, we present a method for predicting a cost-optimal preventive maintenance policy for a repairable system with an increasing Rate of Occurrence Of Failure (ROCOF). We segment the maintenance planning horizon into n discrete and equally-sized periods. For each period, we predict which of three possible actions, (maintain the system, replace the system, or do nothing to the system) should be taken, such that the total net present worth of all future costs is minimized. Our model expands upon previous work by utilizing the concept that maintenance reduces the “effective age” of the system and hence the system ROCOF. We develop the model and evaluate three solution procedures, namely, a random search, a genetic algorithm, and a branch-and-bound approach. The entire approach is illustrated through the use of a numerical example.

    Description / Table of Contents: Riassunto Campioni di cristalli CuIn1−x Fe x Te2 conx che varia tra 0 e 1 sono stati cresciuti con una tecnica di congelamento direzionale programmato. Tutti i composti conx≤0.3 avevano una struttura tipo calcopirite a fase singola, mentre la formazione di fase secondaria è stata osservata perx〉0.3. Le indicazioni di comportamento anomalo delle proprietà elettriche e magnetiche perx≃0.1 potrebbero essere spiegate con la delocalizzazione di elettronid che originano dal mescolamentop/d e con la forte covalenza dei composti tipo calcopirite.
    Abstract: Резюме Выращиваются кристаллические образцы CuIn1−x Fe x Te2; гдеx изменяется от 0 до 1. Все соединения сx≤0.3 имеют структуру халькопирита с единственной фазой, причем дляx〉0.3 наблюдается образование второй фазы. Признаки аномального поведения электрических и магнитных свойств приx≃0.1 могут быть овъяснены делокализациейd электронов, возникающей приp/d смешивании, и сильной ковалентностью халькопиритных соединений.
    Notes: Summary CuIn1−x Fe x Te2 crystal samples withx varying from 0 to 1 have been grown by a programmed-directional-freezing technique. All compounds withx≤0.3 had a single-phase chalcopyrite structure, whereas secondary-phase formation has been observed forx〉0.3. Indications of anomalous behaviour in the electrical and magnetic properties atx≃0.1 could be explained due to the delocalization ofd electrons originating from thep/d mixing and due to the strong covalence of the chalcopyrite compounds.

    Description / Table of Contents: Riassunto Si sono ottenuti dati elettrici da sottili film di CuInS2 del tipop temprati e anodizzati su un vasto intervallo di temperature. Un'analisi dei dati della mobilità della buca rispetto alla temperatura indica che i portatori di carica sono prevalentemente diffusi da impurità neutre e ionizzate e da vibrazioni del modo acustico.
    Abstract: Резюме Получаются злектрические данные для напыленных и отожженных тонких пленок CuInS2 p-типа. Анализ зависимости подвижности дырок от температуры указывает, что носители зарядов преимущественно рассеиваются на нейтральных и ионизованных примесях и на акустических колебаниях.
    Notes: Summary Electrical data from sputtered and annealedp-type CuInS2 thin films have been obtained over a range of temperatures. An analysis of hole mobilityvs. temperature data indicates that the charge carriers are predominantly scattered by neutral and ionized impurities and by acoustic-mode vibrations.

    Notes: Summary Two new species of Iotonchus are described from the Silent Valley, Kerala, India. Females of I. silvallus n.sp. have a mono-prodelphic reproductive tract and a long filiform tail, with subterminal spinneret. Females of I. pseudodigonicus n.sp. have amphidelphic reproductive tracts of which the anterior functional branch is well developed and the posterior branch poorly developed although all components are present, and a long filiform tail with subterminal spinneret; males are also described for this species.

    Notes: Abstract Objectives: To establish an accurate estimate of the prevalence of smoking among high school students in Aleppo–Syria and to characterize the smoking habit in this age group. Design: A cross-sectional survey was performed, in which a self-administered questionnaire was distributed to 10th, 11th and 12th graders. Subjects: A sample of 1587 students (784 males; mean age 16 years, and 803 females; mean age 15.9 years) was studied. This sample was drawn from 16 schools randomly selected from a total of 73 schools in the city. Results: The prevalence of current smoking was 15.9% for males and 6.6% for females. The prevalence of daily smoking was 2.4% for males and 0.5% for females. Almost all smoking categories increased with age and grade. Forty seven percent of male daily smokers were heavy smokers. Peer influence was evident in all stages of the smoking process, especially for males. Parental smoking was also an important associated factor. The combination of parental and siblings smoking was the strongest predictor of the smoking status of the surveyed (OR: 4.4; 95% CI: 2.7–7). Thirty eight percent of male smokers and 47.2% of female smokers smoke out of boredom. Fifty one percent of male smokers were introduced to smoking by a friend. Forty percent of male smokers buy their cigarettes, while 56.6% of female smokers obtain their cigarettes from home. Logistic regression analyses showed that parental and siblings smoking were the most important predictors of ever trying to smoke or current smoking among male and female students. Conclusions: Our study shows that smoking is more frequent in male than female students. Parental and sibling smoking are the most important factors associated with smoking in this population, and peer influence is important particularly in the smoking initiation stage. Pattern of smoking and associated factors differed substantially between males and females in this study.

    Notes: Abstract Understanding the dynamics of the smoking habit among youths at different stages of their development is crucial for the adoption of effective tobacco control policies. We looked at the smoking habits of 576 male university students and compared it with previously studied 555 male high school students in Aleppo–Syria, stratified into four groups with 2-year interval each. The prevalence of current smoking among 1st and 3rd year university students is 18.2% and 29.4% respectively, compared to 10.5% and 22.6% among 10th and 12th year high school students respectively. This study shows a late onset initiation of regular forms of smoking compared to patterns seen in developed countries.
