Povzetek Rezervna sestava kanadskih oboroženih sil (CAF) je sestavljena iz več komponent. Največja komponenta je primarna rezervna sestava (P Res), katere namen je dopolnjevanje redne sestave (Reg F) pri delovanju doma in v tujini. Vloge pripadnikov stalne in primarne rezerve sestave so zato podobne, obstajajo pa tudi pomembni samostojni vidiki. Sodelovanje v primarni rezervni komponenti lahko prinese bistveno drugačne izkušnje in izzive, povezane z zadrževanjem kadra. V tem članku primerjamo podatke iz dveh nedavnih velikih raziskav: ankete kanadskih oboroženih sil o zadrževanju kadra v stalni sestavi (CAF Reg F Retention Survey) (n = 1956) in ankete kanadskih oboroženih sil o zadrževanju kadra v rezervni sestavi (CAF Reserve Force Retention Survey) (n = 3669). Rezultati so pokazali, da je tako pri pripadnikih stalne sestave kot pri pripadnikih rezervne sestave prisoten konflikt med njihovimi vojaškimi, civilnimi in zasebnimi vlogami, čeprav na različne načine. Iz rezultatov je prav tako mogoče sklepati, da so pogoste domneve, da naj bi pripadniki stalne sestave rezerviste dojemali kot manj predane od njih, neutemeljene. Presenetljivo je, da je bila čustvena in normativna predanost rezervistov višja od predanosti pripadnikov stalne sestave, razlog njihovega odhoda pa pogosto povezan z željo po večji in ne manjši vpetosti v vojsko. Priporočila avtorjev se osredotočajo predvsem na izboljšanje ravnovesja med poklicnim in zasebnim življenjem pripadnikov ter na enakost med komponentami. Ključne besede: kanadske oborožene sile, stalna sestava, primarna rezerva, rezervna sestava, zadrževanje kadra. Abstract The Canadian Armed Forces (CAF) Reserve Force comprises several subcomponents. The largest is the Primary Reserve (P Res), whose purpose is to supplement the Regular Force (Reg F) in operations at home and abroad. As such, there is similarity in the roles of Reg F and P Res members, but also important unique aspects. Membership of a primarily part-time force may result in significantly different experiences and retention-related challenges. This article compares data from two recent large-scale surveys: the CAF Reg F Retention Survey (n = 1,956) and the CAF Reserve Force Retention Survey (n = 3,669). The results indicated that both the Reg F members and the reservists experience conflict between their military, civilian, and personal roles, albeit in different ways. They also suggest that Reg F members’ oft-cited perceptions of reservists as being less dedicated than themselves are unfounded. Surprisingly, the reservists’ affective and normative commitment was higher than the Reg F members’, and their reasons for leaving often focused on a desire to be more, rather than less, involved with the military. Recommendations focus on improving work-life balance and equity between the components. Keywords: Canadian Armed Forces, Regular Force, Primary Reserve, Reserve Force, retention

AbstractUnusual short-period comet 29P/Schwassmann-Wachmann 1 inspired many observers to explain its unpredictable outbursts. In this paper large scale structures and features from the inner part of the coma in time periods around outbursts are studied. CCD images were taken at Whipple Observatory, Mt. Hopkins, in 1989 and at Astronomical Observatory, Modra, from 1995 to 1998. Photographic plates of the comet were taken at Harvard College Observatory, Oak Ridge, from 1974 to 1982. The latter were digitized at first to apply the same techniques of image processing for optimizing the visibility of features in the coma during outbursts. Outbursts and coma structures show various shapes.

AbstractThe large-scale coronal structures observed during the sporadically visible solar eclipses were compared with the numerically extrapolated field-line structures of coronal magnetic field. A characteristic relationship between the observed structures of coronal plasma and the magnetic field line configurations was determined. The long-term evolution of large scale coronal structures inferred from photospheric magnetic observations in the course of 11- and 22-year solar cycles is described.Some known parameters, such as the source surface radius, or coronal rotation rate are discussed and actually interpreted. A relation between the large-scale photospheric magnetic field evolution and the coronal structure rearrangement is demonstrated.

AbstractPrecise measurements of heliographic position of solar filaments were used for determination of the proper motion of solar filaments on the time-scale of days. The filaments have a tendency to make a shaking or waving of the external structure and to make a general movement of whole filament body, coinciding with the transport of the magnetic flux in the photosphere. The velocity scatter of individual measured points is about one order higher than the accuracy of measurements.

Trends in the technology development of very large scale integrated circuits (VLSI) have been in the direction of higher density of components with smaller dimensions. The scaling down of device dimensions has been not only laterally but also in depth. Such efforts in miniaturization bring with them new developments in materials and processing. Successful implementation of these efforts is, to a large extent, dependent on the proper understanding of the material properties, process technologies and reliability issues, through adequate analytical studies. The analytical instrumentation technology has, fortunately, kept pace with the basic requirements of devices with lateral dimensions in the micron/ submicron range and depths of the order of nonometers. Often, newer analytical techniques have emerged or the more conventional techniques have been adapted to meet the more stringent requirements. As such, a variety of analytical techniques are available today to aid an analyst in the efforts of VLSI process evaluation. Generally such analytical efforts are divided into the characterization of materials, evaluation of processing steps and the analysis of failures.

Titanium nitride (TiN) films have historically been used as diffusion barrier between silicon and aluminum, as an adhesion layer for tungsten deposition and as an interconnect material etc. Recently, the role of TiN films as contact barriers in very large scale silicon integrated circuits (VLSI) has been extensively studied. TiN films have resistivities on the order of 20μ Ω-cm which is much lower than that of titanium (nearly 66μ Ω-cm). Deposited TiN films show resistivities which vary from 20 to 100μ Ω-cm depending upon the type of deposition and process conditions. TiNx is known to have a NaCl type crystal structure for a wide range of compositions. Change in color from metallic luster to gold reflects the stabilization of the TiNx (FCC) phase over the close packed Ti(N) hexagonal phase. It was found that TiN (1:1) ideal composition with the FCC (NaCl-type) structure gives the best electrical property.

Copper-based metallization has recently attracted extensive research because of its potential application in ultra-large-scale integration (ULSI) of semiconductor devices. The feasibility of copper metallization is, however, limited due to its thermal stability issues. In order to utilize copper in metallization systems diffusion barriers such as titanium nitride and other refractory materials, have been employed to enhance the thermal stability of copper. Titanium nitride layers can be formed by annealing Cu(Ti) alloy film evaporated on thermally grown SiO2 substrates in an ammonia ambient. We report here the microstructural evolution of Cu(Ti)/SiO2 layers during annealing in NH3 flowing ambient.The Cu(Ti) films used in this experiment were prepared by electron beam evaporation onto thermally grown SiO2 substrates. The nominal composition of the Cu(Ti) alloy was Cu73Ti27. Thermal treatments were conducted in NH3 flowing ambient for 30 minutes at temperatures ranging from 450°C to 650°C. Cross-section TEM specimens were prepared by the standard procedure.

CMP-KDO synthetase (CKS) is an enzyme which plays a key role in the synthesis of LPS, an outer membrane component unique to gram negative bacteria. CKS activates KDO to CMP-KDO for incorporation into LPS. The enzyme is normally present in low concentrations (0.02% of total cell protein) which makes it difficult to perform large scale isolation and purification. Recently, the gene for CKS from E. coli was cloned and various recombinant DNA constructs overproducing CKS several thousandfold (unpublished data) were derived. Interestingly, no cytoplasmic inclusions of overproduced CKS were observed by EM (Fig. 1) which is in contrast to other reports of large proteinaceous inclusion bodies in various overproducing recombinant strains. The present immunocytochemical study was undertaken to localize CKS in these cells.Immune labeling conditions were first optimized using a previously described cell-free test system. Briefly, this involves soaking small blocks of polymerized bovine serum albumin in purified CKS antigen and subjecting them to various fixation, embedding and immunochemical conditions.
