Vacuum extractor in the fight against intra- and postnatal fetal mortality

The introduction of obstetric forceps into practice did not satisfy obstetricians, since their use can cause severe damage to the birth canal and the head of the fetus, even if the head is located in the wide part or in the exit of the small pelvis, not to mention the imposition of high forceps, which is dangerous for both the mother and for the fetus.

PENEMUAN ROCK ART BARU DI KAWASAN KARST DESA REJOSARI, KECAMATAN MANTEWE, KABUPATEN TANAH BUMBU, PROVINSI KALIMANTAN SELATAN

>Kawasan karst di Desa Rejosari, Kecamatan Mantewe, Kabupaten Tanah Bumbu, Provinsi Kalimantan Selatan, merupakan bagian dari gugusan karst Mantewe yang membentang luas. Penelitian arkeologi prasejarah pada kawasan karst ini sudah dimulai sejak tahun 2008, di wilayah Desa Mantewe, Desa Bulurejo, Desa Dukuhrejo, dan Desa Rejosari. Potensi budaya prasejarah yang ada pada kawasan karst Mantewe, sangat bagus, seperti situs Gua Sugung (Desa Mantewe), Gua Payung (Desa Bulurejo), dan Gua Bangkai (Desa Dukuhrejo), serta gambar cadas dengan warna hitam pada beberapa gua dan ceruk terutama pada kawasan karst Desa Dukuhrejo. Permasalahan dalam penenelitian ini adalah apakah budaya rock art itu juga ada pada kawasan karst di Desa Rejosari. Metode survei dan ekskavasi dilakukan dalam proses pengumpulan data. Hasil penelitian memperlihatkan adanya kekayaan lukisan dinding gua di Rejosari, yang dapat digunakan untuk melengkapi data arkeologi prasejarah yang ada pada kawasan karst Mantewe secara umum, termasuk budaya rock art yang ada di dalamnya. The karst area in Rejosari Village, Mantewe District, Tanah Bumbu Regency, South Kalimantan Province, is the stretches out wide part of Mantewe karst cluster. Prehistoric archaeological researches on this karst area have been conducted since 2008, starting from the karst area of Mantewe Village, Bulurejo Village, Dukuhrejo Village, and in 2018 was entering Rejosari Village area. The potential of prehistoric culture in the karst is remarkable, such as the existences of Sugung Cave (Mantewe Village), Payung Cave (Bulurejo Village), and Bangkai Cave (Dukuhrejo Village), and also the black of rock art or rock drawings in some caves and niches, especially in Dukuhrejo Village. An interesting issue is filed in this research is whether the rock art culture also exists in Rejosari Village. The method of survey and excavation were used for collecting data in Rejosari karst area. The results suggest that rock art at Rejosari are treasure, that can be complement the existing prehistoric archaeological data in the Mantewe karst area in general, including the rock art culture that exists therein.

High-resolution spectroscopy of two LBV cycles of HR Car

Luminous Blue Variables (LBVs or S Dor Variables) are showing characteristic variability of very long timescales of a decade and more. During their expansion and contraction phases, they move across a wide part of the H-R diagram with dramatic changes of their stellar wind characteristics, radius and temperature. We present results of our long-term spectroscopic monitoring campaigns for the galactic star HR Car with optical spectra taken over 13 years and two minimum and maximum phases observed during this time.

Modification of a semi-surgical method for the treatment of chronic tonsillitis

It is known that in chronic tonsillitis caseous plugs are formed mainly in the lacunae of the first order, in their wide part, closer to the exit. The reason for the formation of stagnant pathological secretions and plugs in the lacunae is the difficulty of evacuation from them due to the narrowness of the mouth or its deformation after repeated inflammatory processes.

A Junction-Orifice-Fiber Entrance Layer Model for Capillary Permeability: Application to Frog Mesenteric Capillaries

The recent serial section electron microscopic studies by Adamson and Michel (1993) on microves gels of frog mesentery have revealed that the large pores in the junction strand of the interendothelial cleft are widely separated 150 nm wide orifice-like breaks whose gap height 20 nm is the same as the wide part of the cleft. In this paper a modified version of the model in Weinbaum et al. (1992) is first developed in which this orifice structure is explored in combination with a random or ordered fiber matrix layer that is at the luminal surface and/or occupies a fraction of the wide part of the cleft. This basic orifice model predicts that for the measured Lp to be achieved the fiber layer must be confined to a relatively narrow region at the entrance to the cleft where it serves as the primary molecular filter. The model provides a much better fit of the permeability P for intermediate size solutes between 1 and 2 nm radius than the previous model in Weinbaum et al., where the junction strand breaks were treated as finite depth circular or rectangular pores, but like the previous model significantly underestimates P for small ions. However, it is shown that if a small frequent pore of 1.5 nm radius with characteristic spacing comparable to the diameter of the junction proteins or a continuous narrow slit of approximately 1.5 to 2.3 nm gap height is also present in the continuous part of the junction strand, small ion permeability can also be satisfied. The 1.5 nm radius pore does not significantly change Lp, whereas the continuous narrow slit provides a contribution to Lp that is comparable to, or in the case of the 2.3 nm slit greater than, the widely spaced 150 nm orifices. Thus, for the narrow slit the contribution to Lp from the orifices can be as low as 1.0×10−7 cm/s/cm H2O and it is also possible to satisfy the 2.5 fold increase in permeability that occurs when the matrix is enzymatically removed from the luminal side of the cleft, Adamson (1990). The likelihood of each of these cleft structures is discussed.

Why Peasants Rebel: The Case of Peru's Sendero Luminoso

In this article I shall examine the origins of a major rural revolutionary movement, Sendero Luminoso (Shining Path). An extremist Maoist organization, Sendero has gained considerable peasant support in Peru's southern highlands, especially in the Ayacucho area. Although peasant unrest has been endemic in Peru, the scope and intensity of the current movement are unprecedented. Never before has a Peruvian guerrilla group ranged over such a wide part of the country, and never before has such a group threatened the order of daily life in the capital.

Pictographs from Tramping Lake, Manitoba

In presenting the accompanying sketches and observations, it must be stated that they were taken from a layman's viewpoint, and some significant details may have been omitted in one or two instances. Data were not collected with the thought of scientific publication, but since it is believed there has been no previous recording of Indian pictographs from a locality as far north in Manitoba as the occurrence here described, the following brief observations are presented at the suggestion of Dr. Douglas Leechman of the National Museum of Canada, Ottawa.The pictographs occur on the west side of the north arm of Tramping Lake, Manitoba (Fig. 36). They are about one mile north of the wide part of Tramping Lake, at approximately 54°43’ N. latitude and 100°05′ W. longitude. Tramping Lake lies between Wekusko (Herb) Lake on the east and Reed Lake on the west and is a portion of the Grass River system, one of the early canoe routes of the area. Peter Pond has referred to this canoe route on his map, dated 1785, as the “middle road to Hudson's Bay.“
