The Investment Environment And The Problems Of Origination Of Investorsβ Ownership Over Real Estate In Georgia
In this research of the Investment Environment and the Problems of Origination of Investorsβ Ownership over Real Estate in Georgia we have discussed importance of attraction of the direct foreign investments and the problems existing in the economy of Georgia. Besides, we have analyzed the direct foreign investments based on the statistic data and proved the effective role of the direct foreign investments in stimulation of the Georgian economy. In our research we have analyzed the problematic aspects preventing attraction of investments in Georgia. Also we have considered the ways and methods promoting influx of direct foreign investments in Georgia. The main accent is made on the Georgian legislative basis
BM@N and MPD experiments at NICA
The project NICA (Nuclotron-based Ion Collider fAcility) aims to study hot and baryon rich QCD matter in heavy ion collisions in the energy range SNN = 4 β 11 GeV. The rich heavy-ion physics program will be performed at two experiments, BM@N (Baryonic Matter at Nuclotron) at beams extracted from the Nuclotron, and at MPD (Multi-Purpose Detector) at the NICA collider. This program covers a variety of phenomena in strongly interacting matter of the highest baryonic density, which includes study of collective effects, production of hyperon and hypernuclei, in-medium modification of meson properties, and event-by-event fluctuations

Epidemiology of Visceral Leishmaniasis in Georgia
This study investigated the transmission and prevalence of Leishmania parasite infection of humans in two foci of Visceral Leishmaniasis (VL) in Georgia, the well known focus in Tbilisi in the East, and in Kutaisi, a new focus in the West of the country. The seroprevalence of canine leishmaniasis was investigated in order to understand the zoonotic transmission. Blood samples of 1575 dogs (stray and pet) and 77 wild canids were tested for VL by Kalazar Detect rK39 rapid diagnostic tests. Three districts were investigated in Tbilisi and one in Kutaisi. The highest proportions of seropositive pet dogs were present in District #2 (28.1%, 82/292) and District #1 (26.9%, 24/89) in Tbilisi, compared to 17.3% (26/150) of pet dogs in Kutaisi. The percentage of seropositive stray dogs was also twice as high in Tbilisi (16.1%, n = 670) than in Kutaisi (8%, n = 50); only 2/58 wild animals screened were seropositive (2. 6%). A total of 873 Phlebotomine sand flies were collected, with 5 different species identified in Tbilisi and 3 species in Kutaisi; 2.3% of the females were positive for Leishmania parasites. The Leishmanin Skin Test (LST) was performed on 981 human subjects in VL foci in urban areas in Tbilisi and Kutaisi. A particularly high prevalence of LST positives was observed in Tbilisi District #1 (22.2%, 37.5% and 19.5% for ages 5β9, 15β24 and 25β59, respectively); lower prevalence was observed in Kutaisi (0%, 3.2% and 5.2%, respectively; P<0.05). This study shows that Tbilisi is an active focus for leishmaniasis and that the infection prevalence is very high in dogs and in humans. Although exposure is as yet not as high in Kutaisi, this is a new VL focus. The overall situation in the country is alarming and new control measures are urgently needed
Seroepidemiology and molecular diversity of Leishmania donovani complex in Georgia
Background
Leishmaniasis includes multiple clinical syndromes, most notably visceral, cutaneous, and mucosal forms. Visceral leishmaniasis (VL), also known as kala-azar, is a potentially fatal disease endemic to large parts of Africa and Asia, and in South-Eastern Europe (Greece, Turkey, Georgia). Visceral leishmaniasis is a parasitic zoonosis caused by species ofΒ the L. donovani complex. In the classical epidemiological model the main reservoir for VL are canines.
Methods
The study included a cohort of 513 individuals of both genders (190 males and 323 females) from the ages of 1 to 70Β years that were screened in ten villages across two districts in Kakheti using the Kalazar Detectβ’ rK39 rapid diagnostic test. The phylogenetic diversity patterns of local strains, based on the rDNA internal transcribed spacer (ITS) sequences, were assessed for samples obtained from patients with suspected L. donovani infection, from canine reservoirs and from Phlebotomus sand flies obtained from different geographical areas of Georgia and from Azerbaijan.
Results
Out of a total of 600 domestic dog blood samples 95 (15.8Β %) were positive by rK39 rapid diagnostic tests. For symptomatic domestic dogs, the testing of conjunctival swabs or bone marrow aspirates revealed a higher VL incidence in Kvareli District (Kvareli; 19.4Β %, nβ=β329) compared with that observed for Sagarejo District (Sagarejo; 11.4Β %, nβ=β271). A total of 231 sand flies of both genders were collected during the 2-month period; of the 114 females, 1.75Β % were PCR positive for the presence of Leishmania spp.
Conclusions
VL infection rates remain high in both canines and humans in Georgia, with disease in several known natural foci. The genetic relationships derived from rDNA internal transcribed spacer (ITS) sequence comparisons identified genetic subgroups, revealing preliminary insights into the genetic structure of L. donovani complex members currently circulating in the South Caucasus and demonstrates the utility of ITS-based genotyping in the resource-limited country of Georgia
Status of the NICA project at JINR
AbstractThe NICA (Nuclotron-based Ion Collider fAcility) project is now under active realization at the Joint Institute for Nuclear Research (JINR, Dubna). The main goal of the project is a study of hot and dense strongly interacting matter in heavy ion (up to Au) collisions at the centre-of-mass energies up to 11 GeV per nucleon. Two modes of operation are foreseen, collider mode and extracted beams, with two detectors: MPD and BM@N. The both experiments are in preparation stage. An average luminosity in the collider mode is expected as 10E27 cm-2 s-1 for Au (79+). Extracted beams of various nucleus species with maximum momenta of 13 GeV/c (for protons) will be available. A study of spin physics with extracted and colliding beams of polarized deuterons and protons at the energies up to 27 GeV (for protons) is foreseen with the NICA facility. The proposed program allows one to search for possible signs of phase transitions and critical phenomena as well as to shed light on the problem of thenucleon spin structure

Stability study and time resolution measurement of Straw Tube detectors
Straw tube detectors are single wire proportional counters that are widely
used as a tracking device. We have carried out RD with a straw tube
detector prototype. The motivation of this work is to study the stability of
the performance in terms of gain and energy resolution of the straw tube
detectors under high rate radiation. Two different methods are incorporated to
perform this study. The gain and energy resolution of the detector are studied
along with its variation with ambient temperature and pressure. X-ray from a
radioactive source is used to irradiate the detector and the same source is
also used to monitor the energy spectra simultaneously for calculation of gain.
Variation of the gain and energy resolution of the straw tube detector under
X-ray irradiation in Ar/CO gas mixture is discussed in this article. We
have also estimated the time resolution of the straw tube detectors that can be
best achieved with cosmic rays as trigger for the same gas mixture. The details
of the measurement process and the experimental results are presented in this
article
