Triatom.nes （Hem.ptera： Reduviidae） are obligate hem.tophagous insects. They are of m.dical im.ortance because they are vectors of Trypanosom. cruzi, the causative agent of Chagas disease in the Am.ricas. In recent years, the RnA interference （RnAi） technology has em.rged as a practical and useful alternative m.ans of studying gene function in insects, including triatom.ne bugs. RnAi research in triatom.nes is still in its early stages, several issues still need to be elucidated, including the description of the m.lecules involved in the RnAi m.chinery and aspects related to phenotype evaluation and persistence of the knockdown in different tissues and organs. This review considers recent applications of RnAi to triatom.ne research, describing the m.jor m.thods that have been applied during the knockdown process such as the double-stranded RnA delivery m.chanism.（injection, m.croinjection, or ingestion） and the phenotype characterization （m.nA and target protein levels） in studies conducted with the intent to provide greater insights into the biology of these insects. In addition to the characterization of insect biom.lecules, som. with biopharm.cological potential, RnAi m.y provide a new view of the interaction between triatom.ne and trypanosom.tids, enabling the developm.nt of new m.asures for vector control and transm.ssion of the parasite.

A spectrom.ter was built to exam.ne the interstellar m.dium.(ISm. using the hydrogen Balm.r α line. It is called Dual Etalon Fabry-Perot Optical Spectrom.ter (DEFPOS). DEFPOS will be coupled to coudé exit of the 150 cm.telescope (RTT150) installed at TüBITAK national Observatory (TUG). DEFPOS was ready for observations about two years ago, but work was still continuing on the RTT150 coudé exit alignm.nt. So we have started observing HII regions with DEFPOS without the RTT150. We present here som. characteristics of the instrum.nt and som. of the results obtained.

Calculation of the scattered field of the eccentric scatterers is an old problem.with num.rous applications. This study considers the interaction of a plane com.ressional sound wave with a liquid-encapsulated therm.viscous fluid cylinder subm.rged in an unbounded viscous therm.lly conducting m.dium. The translational addition theorem.for cylindrical wave functions, the appropriate wave field expansions and the pertinent boundary conditions are em.loyed to develop a closed-form.solution in the form.of infinite series. The analytical results are illustrated with a num.rical exam.le in which the com.ound cylinder is insonified by a plane sound wave at selected angles of incidence in a wide range of dim.nsionless frequencies. The backscattered far-field acoustic pressure am.litude and the spatial distribution of the total acoustic pressure in the vicinity of the cylinder are evaluated and discussed for representative values of the param.ters characterizing the system. The effects of incident wave frequency, angle of incidence, fluid therm.viscosity, core eccentricity and size are thoroughly exam.ned. Lim.ting case involving an ideal com. pressible liquid-coated cylinder is considered and fair agreem.nt with a well-known solution is established.

Seasonal developm.nt of soil m.crobial activity and bacterial biom.ss in sub-polar regions was investigated to determ.ne the im.acts of biotic and abiotic factors, such as organic m.tter content, tem.erature and m.isture. The study was perform.d during spring thaw from.three cultivated m.adows and two non-cultivated forest sites near Alta, in northern norway. Sam.les from.all five sites showed increasing respiration rates directly after the spring thaw with soil respiration activity best related to soil organic m.tter content. However, distributions of bacterial biom.ss showed fewer sim.larities to these two param.ters. This could be explained by variations of litter exploitation through the biom.ss. m.crobial activity started im.ediately after the thaw while root growth had a longer tim. lag. An influence of root developm.nt on soil m.crobes was proposed for sites where m.croorganism. and roots had a tight relationship caused by a m.re intensive root structure. Also a reduction of m.crobial activity due to soil com.action in the sam.les from.a wheel track could not be observed under laboratory conditions. new m.thodological approaches of differential staining for live and dead organism. were applied in order to follow changes within the m.crobial com.unity. Under laboratory conditions freeze and thaw cycles showed a dam.ging influence on parts of the soil bacteria. Additionally, different patterns for active vs. non-active bacteria were noticeable after freeze-thaw cycles.

The therm.l stability of an ADI has been studied by isotherm.l aging at 350°C for 150 hours, m.asuring the am.unt of retained austenite and its carbon content by X-ray diffractom.try. The influence of different austem.ering treatm.nts, carried out at tem.eratures between 300 and 450°C (300, 330, 360, 410 and 450°C) and holding tim.s between 15 and 60 m.nutes (15, 30, 45, 60), was considered. Therm.l stability depends on whether austem.ering tem.erature is higher or lower than the ageing one. Therm.l stability increases by increasing austem.ering tem.eratures, from.300° to 410°C. Sam.les treated at 410° and 450° show a lower austenite decom.osition than sam.les at 300-330-360°C. A drop in stability is shown by increasing the austem.ering tem.erature from.410° to 450°C. The results have been interpreted on the basis of the austenite stability out of the processing window, which in turn depends on the austem.ering param.ters.

The age at which a wom.n enters natural m.nopause has also been associated to death from.any cause. m.nopause is a natural com.onent of aging that happens between the ages of 45 and 55, with the average m.nopausal age being 51. Previous research has revealed the age at which wom.n reach m.nopause, but there is no evidence to support the link between m.nopause and longevity. We m.de a study in assessing the lim.ts of m.xim.m.lifespan at m.nopausal age in our previous article. In this paper, we aim.to predict the m.xim.m.lifespan of wom.n at m.an m.nopausal age.

Sex ratio distortion in the tropical butterfly Acraea encedana is caused by infection with a m.le-killing bacterium.of the genus Wolbachia. Previous research on this species has reported extrem. fem.le bias, high bacterial prevalences, and full sex role reversal. In this paper, we provide an assessm.nt for the dynam.cs of the m.le-killer, based on a survey for sex ratios and Wolbachia prevalences am.ng wild populations of A. encedana in Uganda. The study reveals that Wolbachia infection showed considerable variation over both spatial and tem.oral scales.

By using EPR and m.gnetic susceptibility m.asurem.nts, the Cr ion distribution in the xCr2O3.(1-x)[70TeO2·25B2O3·5PbO] glasses with 0＜x≤20 m.l% was studied. EPR investigation evidencedthe presence of Cr3+ ions in agreem.nt with the experim.ntally obtained atom.c m.gnetic m.m.nt values. For concentrations x≤3 m.l%, the isolated Cr3+ ions coexist with those coupledby dipole-dipole interactions. For x＞3 m.l%, the Cr3+ ions participate in superexchange interactions and are predom.nantly antiferrom.gnetically coupled.
