The paper presents problems of gravity units, the reference system for the acceleration of gravity, that is then gave a brief overview of the instruments that allow us the absolute determination of gravity, ie the determination of gravity in the full amount. Among many instruments available on the market today, absolute gravimeters FG5, FG5L and A10 are shown.

This paper presents an overview of the importance of periodic testing and calibration of geodetic measuring instruments by standard procedures in order to achieve the desired results. Special attention is placed on the standard procedures of testing and calibration of complex geodetic instruments for the GNSS measurements, which are in geodetic mass practice for some 20 years. Standard ISO test procedure for RTK instruments was presented in the paper, as well as method for testing the accuracy of receiver using the geodetic test network.

The early signs of brain ischemia are key indicators of secondary brain injury and their recognition on time can ultimately save life. Direct recording of cerebral ischemia is possible using the method of cerebral microdialysis (CM). This paper presents results of the five-year experience in applying this method at University Department of Neurosurgery, Sarajevo University Clinical Center in Sarajevo. In this observational prospective clinical study, the treatment and outcome of 51 patients with subarachnoid hemorrhage (SAH) and traumatic intracranial hemorrhage (tICH) undergoing neurosurgery and consequently treated conservatively at Neurosurgical Intensive Care Unit (NICU) were analyzed. All patients were followed up by unified monitoring at NICU and additionally by the CM method. Between December 2006 and September 2010, CM monitoring was performed in 51 patients: 18 patients with SAH and 33 patients with tICH. In all patients, samples were obtained on 367 occasions, yielding a total of 3314 samples for biochemical parameters (mean 64.98 per patient, range 42-114 samples). Positive correlation was found between glucose level and outcome at one-year follow up (when glucose level was lower, the patient Glasgow Outcome Scale (GOS) score was worse). The correlation coefficient for glycerol was negative (r=-0.81), and so was for the lactate/pyruvate ratio. There was a significant difference in patient outcome in favor of the group of patients monitored by use of CM in terms of poor and good outcome graded according to GOS score 12 months after the injury compared with the group of patients not monitored with CM (P<0.028). According to our experience, we believe that CM enables early initiation of appropriate therapeutic strategies to overcome cerebral ischemia and secondary brain damage, eventually leading to better patient outcome.

In this paper, the different ways to identify changes in remote sensing are given. Various authors have presented different methods of detecting changes on the Earth's surface. Detection of changes, among other things, are very important for tracking changes, as well as assessment and evaluation of changes and interrelations of natural and artificial objects. All this leads to better understanding of potential causes of change.

Among obstetric techniques, cesarean section seemed to represent a well-defined procedure and significant advances in this intervention were considered to be unlikely. However, obstetric surgery has recently undergone many improvements. In 1972, Joel-Cohen presented a new method for transverse incision of the abdomen. This method, with some modifications, was integrated into the Misgav-Ladach cesarean section. The philosophy of this technique is to cause the least possible damage to tissues, to refrain from superfluous steps, and to make the intervention the simplest possible. Advantages of this method are lower incidence of fever and urinary tract infection, reduced use of antibiotics and narcotics, faster re-establishment of normal bowel function, shorter maternal hospital stay and less postoperative adhesion formation. The Misgav-Ladach method of cesarean section is suitable for emergency and elective procedures, justifying its use in daily routine.

The main goal of GIS is to identify geografic coordiantes and attributes of stationary objects. That means that the uses of GIS are very much limited. So, there exists a need for a technology which will enable identification of objects if they are not stationary. RFID technology is the best example where this problem can be solved. Integrating GIS and RFID technologies we are able to follow and identify indoor or outdoor objects that are not stationary. RFID readers/writers are becoming cheaper just like it’s the case with other computer technologies. Today, some RFID devices can also process and transfer data to GIS servers. On the other side, development of GIS is becoming more affordable for the same reasons why RFID devices are cheaper. Therefore, if we enable GIS and RFID integration through internet, we can have all kinds of new possibilities which will solve industrial problems of todays and future.

This paper presents a Hannover method and its application in the deformation analysis. Hannover method determines the displacements of the geodetic network points, based on the geodetic measurements using the statistic methods. Application of determining unstable points displacements is shown in the example of microtriangulation network.

Background and purpose: Having in mind the results of our previous work, which suggested antimicrobial activity of some 3-cynnamoyl-4-hydroxycoumarins, we carried out the synthesis of several new derivatives of this group. The microbiological activity of compounds was tested by the diffusion and dilution methods on various species of bacteria. The aim of the study was to evaluate the influence of the substituents on antimicrobial activity. Material and methods: A series of new 3-cynnamoyl-4-hydroxycoumarins was prepared by the reaction of nucleophylic addition from 3-acetyl-4-hydroxycoumarin acting on appropriate aromatic aldehydes. The microbiological activity of compounds was tested by the diffusion and dilution methods on species of bacteria Pseudomonas aeruginosa, Echerichia coli, Salmonella typhimurium, Bordatella bronchiseptica, Bacillus subtilis, and Staphyloccocus aureus. Results: The synthesis of new 3-cynnamoyl-4-hydroxycoumarins was carried out. The elementary content of the synthesized compounds was confirmed by elementary analysis, and structures were confirmed with IR-spectrophotometry and 1 H-NMR spectrophotometry.

Esta investigacion tuvo por objetivos conocer la percepcion de personas que viven en Vitoria da Conquista, estado de Bahia, sobre la asistencia prestada en la salud publica, asi como identificar problemas recurrentes del Sistema Unico de Salud en aquel contexto. Es un estudio exploratorio y cuantitativo, realizado en enero de 2010 con 100 usuarios. Los datos fueron recogidos por medio de aplicacion de cuestionario estructurado y analizados con ayuda de estadistica descriptiva. Los resultados apuntaron que parte de los entrevistados desconoce algunos de los varios servicios prestados en la atencion primaria de salud, ademas de estar insatisfechos con el funcionamiento del Sistema Unico de Salud ofrecido.
