INTRODUCTION The authors analyze contemporary methods of contraception. Regarding oral contraception, they point to agents which decrease the efficacy of oral contraception. They also deal with agents which increase the level of estrogen, thus increasing side effects (paracetamol, vitamin C). ORAL CONTRACEPTIVES Oral contraceptives may also have an impact on the efficacy of some medications (anticonvulsants, antidepresants). Health risks of oral contraceptives are also mentioned, as well as WHO's, guidelines for women using contraceptives based on risks and benefits. OTHER METHODS OF CONTRACEPTION The authors also offer criteria for use of bioactive intrauterine devices (IUD), with recommendations of WHO. Besides men's, there are women's condoms, which are very reliable protection against infections, but their negative side is that they are rather expensive. Bad sides of vaginal wash are also emphasized, although this method is rather widespread in the world. CONCLUSION At the end, the authors quote the Internationa Family Planning Fund (IFPF) which considers IUD to be the most reliable method of contraception nowadays.

Raman spectroscopy is a powerful diagnostic tool, enabling tissue identification and classification. Mostly, the so-called fingerprint (approximately 400-1800 cm(-1)) spectral region is used. In vivo application often requires small flexible fiber-optic probes, and is hindered by the intense Raman signal that is generated in the fused silica core of the fiber. This necessitates filtering of laser light, which is guided to the tissue, and of the scattered light collected from the tissue, leading to complex and expensive designs. Fused silica has no Raman signal in the high wave number region (2400-3800 cm(-1)). This enables the use of a single unfiltered fiber to guide laser light to the tissue and to collect scattered light in this spectral region. We show, by means of a comparison of in vitro Raman microspectroscopic maps of thin tissue sections (brain tumors, bladder), measured both in the high wave number region and in the fingerprint region, that essentially the same diagnostic information is obtained in the two wave number regions. This suggests that for many clinical applications the technological hurdle of designing and constructing suitable fiber-optic probes may be eliminated by using the high wave number region and a simple piece of standard optical fiber.

High-spin terminating bands in heavy nuclei were first identified in nuclei around Er-158(90). While examples of special terminating states have been identified in a number of erbium isotopes, almost nothing is known about the states lying beyond band termination. In the present work the high-spin structure of Er-157 has been studied using the Gammasphere spectrometer. The subject of triaxial superdeformation and 'wobbling' modes in Lu nuclei has rightly attracted a great deal of attention. Very recently, four strongly or superdeformed (SD) sequences have been observed in Hf-174 and ultimate cranker calculations predict, such structures may have significant triaxial deformation. We have performed two experiments in an attempt to verify the possible triaxial nature of these bands. A lifetime measurement was performed to confirm the large (and similar) deformation of the bands. In addition, a high-statistics, thin-target experiment was run to search for linking transitions between the SD bands and possible wobbling modes.

This article focuses on the transformation process and changes in the manners of interpretation undergone by Bosnian traditional urban song from its emergence, through the first melographic transcriptions in late 19th century – that is, from Ludvik Kuba’s times – through the development of electronic media. *** Prispevek obravnava proces transformacije in spremembe interpretativnih nacinov tradicionalne pesmi v urbanem bosanskem okolju od nastanka preko prvih notnih zapisov konec 19. stoletja, torej casa Ludvika Kube, pa vse do razvoja elektronskih medijev.
