Validatie van TRISULA voor Intruderende dichtheidsstromen
Een computerprogramma dat ontwikkeld is om er stromingen mee te berekenen die optreden in zeëen en estuaria, dient ook rekening te houden met de stromingen die veroorzaakt kunnen worden door de verschillen in dichtheid. Dit is het geval bij het programmapakket TRISULA. Echter, de bewegingsvergelijkingen ondergaan een aantal vereenvoudigingen. Zo wordt een hydrostatische drukverdeling verondersteld. Intrusies zijn een bepaalde klasse van dichtheidsstromen die een belangrijke rol kunnen spelen bij mengingsprocessen in zeëen en estuaria. Daarbij komt dat intrusies relatief gemakkelijk in een laboratorium te simuleren zijn. De vorm van een intrusie is echter zodanig dat, met name bij het front, niet geheel voldaan wordt aan deze voorwaarde die gesteld moeten worden om toepassing van de vergelijkingen die door TRISULA gebruikt worden aannemelijk te maken. Deze klasse van dichtheidsstromen vormt dus een interessante test voor de mogelijkheden van TRISULA. Om nu de mogelijkheden van TRISULA na te gaan is een aantal testgevallen met intrusies geformuleerd. De verificatie van de met TRISULA verkregen resultaten wordt uitgevoerd deels via zelf uitgevoerde experimenten, deels aan de literatuur ontleende waarden. Over het algemeen lijken de met TRISULA verkregen waarden goed op de experimenteel verkregen waarden. Er doen zich echter ook afwijkingen voor. Deze afwijkingen lijken deels aan meetfouten toegeschreven te moeten worden. In andere gevallen blijkt TRISULA echter fysisch onrealistische uitkomsten te geven, zoals een concentratie van de verticale snelheid in slechts enkele roosterpunten, of een artificiële opmenging van opgeloste stof in de verticaal. In TRISULA wordt in de verticaal de transformatie toegepast. Dit houdt in dat alle componenten van de basisvergelijkingen getransformeerd worden . In het geval van tweede-orde afgeleiden stuit dit echter op problemen bij het oplossen van de vergelijkingen door het optreden van kruistermen. Daarom worden de kruistermen verwaarloosd. Dit kan een kunstmatige, verticale stroming tot gevolg hebben. Er zijn bij de numerieke experimenten echter geen afwijkingen geconstateerd die toe te schrijven zouden zijn aan het onvolledig uitvoeren van de ~transformatie.(Bij het simuleren van de intrusies zijn echter de viscositeit en de diffusiviteit verwaarloosd).Environmental Fluid DynamicsHydraulic EngineeringCivil Engineering and Geoscience

The Trisula Bridge is a connecting bridge over the Brantas River, has a span length of 200 m and a vehicle floor width of 12 meters. The existing condition of the bridge is a steel frame bridge with a division of 3 spans which is supported using 2 (two) pillars and 2 (two) abutments, because of this the river width becomes less wide due to the need for pillars, so it is not suitable for a long span bridge type because it affects the required foundation strength. In this final assignment the author draws on the available cases, to provide a reference for the remodeling of the Trisula Bridge with an asymmetric cable stayed structure to reduce the number of pillars to widen the river flow, and as a new icon in Blitar City. This final assignment discusses "Design of the Trisula Blitar Asymmetric Cable Stayed Bridge" which is in the Kademangan area of Blitar City. The asymmetric cable stayed bridge design has the concept of a structure that can support rigid horizontal elements by a row of straight cables stretched at an angle and connected to the tower as the main support, using the balanced cantilever method. The auxiliary program is MIDAS CIVIL software on the upper structure and SAP 2000 on the lower structure, and refers to various regulations according to the standards SNI 1725 2016, SNI 2833 2016, RSNI 2833 2016, RSNI T 02 2005, AISC 360 - 10, ACI 318 - 08. The results of this design obtained a vehicle floor structure with a thickness of 250 mm with an asphalt thickness of 50 mm, the bridge girder uses steel WF 800.300.26.18 on the transverse girder, WF 600.300.12.20 on the longitudinal girder, WF 200.200.8.12 on the cantilever girder, the main longitudinal girder as The compression member is a box girder with dimensions of 1.5 m x 0.9 m, a pylon with dimensions of 5 m x 3 m, cable and anchor dimensions using VSL2000 unit 6, and the type of foundation used is a bored pile with a diameter of 1 m. The components that make up the bridge structure are then controlled for stability, referring to existing regulations

CORRELATION OF FOLLICLE STIMULATING HORMONE AND LUTEINISING HORMONE WITH TESTICULAR SPERM BIOPSY RESULT
Objective: To investigate the correlation of follicle stimulating hormone (FSH) and luteinising hormone (LH) with testicular sperm biopsy result in azoospermia patients. Material & methods: This is a cross sectional descriptive analytic study. Data were collected from medical record in Klinik Permata Hati Sardjito General Hospital Yogyakarta. We divided them into two groups, sperm group and non-sperm group of sperm biopsy result. We recorded the level of FSH and LH pre-operation. The results were expressed as mean ± standard deviation (SD). The correlation coefficient (r) between various parameters was determined by analysis for Spearman’s rank correlation test. Results: We found 35 patients who met the inclusion and exclusion criteria during 2010-2012, who performed testicular biopsy, age range between 28-44 yo. The mean of FSH on sperm group (12.75 mIU/mL) was higher than non-sperm group (7.26 mIU/mL). The mean of LH on sperm group (5.8 mIU/mL)was also slightly higher than non-sperm group (5.70 mIU/mL). We found weak correlation between FSH level and testicular biopsy (r = 0.095), while on LH level was found negative correlation with testicular biopsy (r = -0.053). There were 42.85% patients with negative sperm result within normal range of FSH and 100% with normal range of LH. The Level of FSH with positive result ranged between 1.94-19.7 mIU/mL and LH level with positive result were 1.38-17.69 mIU/mL. Conclusion: FSH and LH were important plasma hormones correlated with spermatogenesis. FSH level between 1.94-19.7 mIU/mL and LH level between 1.38-17.69 mIU/mL could be used as reliable criteria for testicular sperm biopsy.Keywords: Follicle stimulating hormone, luteinising hormone, testicular sperm biopsy, azoospermia

EFFICACY OF INTRAVESICAL INSTILLATION OF NETILMICIN ON MANAGING UTI
INTRODUCTION Urinary tract infections (UTIs) are common, affect men and women of all ages, and vary dramatically in their presentation and sequelae. They are a common cause of morbidity and can lead to significant mortality. New antimicrobial agents that achieve high urinary and tissue levels, that can be administered orally, and that are not nephrotoxic have significantly reduced the need for hospitalization for severe infection. Shorter-course therapy and prophylactic antimicrobial agents have reduced the morbidity and cost associated with recurrent cystitis in women. Intravesical instillation of aminoglycoside has been used empirically as prophylaxis and to treat bacilluria in spinal-cord-injured patients undergoing clean intermittent catheterization.METHODS In a prospective clinical trial performed in the urologic ward of Dr. Sardjito Hospital, yogyakarta, Indonesia, we studied 56 patients who has indwelling urethral catheter more than 4 days. Patients were divided into two groups. In group 1 (28 patients) one-time intravesical instillation of Netilmicin 25 mg was administred, and in group 2 (28 patients) none were given any treatment. Urinalysis was evaluated before and after instillation of Netilmicin. Statistical data and results were studied using descriptive statistics as median (minimum and maximum). To compare the response to treatment, Chi-Square test was used in two groups. Consequently, the data were analyzed using the SPSS 17 software.RESULTS Urinalysis were evaluated in two groups 4 days after intravesical instillation of 50 mg netilmicin. The patients we studied, the median age 59 years old (min. 29; max. 81). In the first group we found 22 (78,5 %) patients still without UTI, 6 (21,5 %) patients with UTI, in the second group we found 4 (14,3 %) still without UTI, 24 (85,7 %) patients with UTI. The difference was statistically significant (p=0.0001)CONCLUSIONS Intravesical instillation of netilmicin on patients with indwelliing urethral catheter were effective on preventing catheter-related UTI.Keywords : UTI, indwelling catheter, netilmicin, intravesical antibiotic instillation
