Appendicocecal Fistula – A Rare Complication of Appendicitis
Fistulisation of appendix to other organs or to the exterior through abdominal wall is a rare complication of appendicitis. We present one such rare case of appendicocecal fistula due to appendicitis in a patient initially managed conservatively for appendicular lum
The role of heparin and heparin-binding growth factors in pre-eclampsia
The aims of this study tested the hypothesis that expression of heparin-binding growth factors (HBGFs) in normal placental development was altered in a specific pregnancy disorder preeclampsia. HBGFs bind to heparin, a glycosaminoglycan (GAG) affecting activity. I investigated the role of heparin and HBGFs in pathophysiology of pre-eclampsia. Placental tissue from a cohort study of 87 women was performed following uncomplicated pregnancy at term, but not in labour (TNL, n=26), preterm labour (PTL, n=17), following labour onset (TL, n=21), first trimester (FNL, n=4) and pre-eclampsia (PE, n=19). The HBGFs studied were vascular endothelial growth factor (VEGF), placental growth factor (PLGF), fibroblast growth factor 2 (FGF2), hepatocyte growth factor (HGF), platelet-derived growth factor (PDGF), heparin-binding epidermal growth factor (HB-EGF), midkine (MK), pleiotrophin (PTN), and cluster differentiation (CD105). The localisation of HBGFs and receptors VEGFR-1, /(sflt-1), PLGFR-1, VEGFR-2 and FGF2R-1 in placenta were detected. The expression of VEGF, PLGF, FGF2, HGF, PDGF, CD105 was confined to villous trophoblast, endothelial cells except for MK, HB-EGF and PTN was specifically to villous trophoblast. The total RNA production in human placentae samples (n=7) from PE and controls were analysed using qRTPCR. Placental expression of mRNA was extracted for primer assays of PLGF, FGF2, MK, PTN, and endogenous housekeeping gene as Succinate dehydrogenase complex subunit A (SDHA). FGF2 and SDHA mRNA expression was significantly different using Mann-Whitney U test. An in vitro villous trophoblast invasion model was performed with human fibrosarcoma HT1080 invasive cells (positive control), mouse embryonic fibroblast NIH/3T3 non-invasive cells (negative control) and immortalised human primary villous trophoblastic cell lines TCL-1.The greatest stimulation was by FGF2, PDGF-BB, HGF, MK and co-incubation with heparin enhanced these responses, except for PTN using the Mann-Whitney U test. Heparin’s role is indicated in mediating the effects of HBGFs. It’s suggests heparin therapeutic use in the treatment of pre-eclampsia
Soil Nitrogen Mineralization as Affected By Drying, Liming and Sewage Sludge Addition
This investigation was undertaken to determine the effect of drying and liming on soil nitrogen mineralization, to measure in N-supplying power of soils and to assess the effect of soil type on mineralization of nitrogen from sewage sludge. Laboratory, greenhouse and field experiments were conducted on a number of soils from the Hawaiian Islands.
Air and oven-drying for 12 weeks increased the amount of mineral-N in five soils studied. Oven-drying released about 10-40 times more N than air-drying. Most of the mineral-N was released as NH^-N. Cultivation of undisturbed soil in the field resulted in more N being mineralized than from soil which was left undisturbed. Dry matter yield of corn was also affected when grown on air and oven-dried soils. Air-drying was more beneficial to corn yield in the Kaiwiki (Typic Hydrandepts). However, oven-drying had harmful effects on the growth of corn in this soil. Air-drying had little effect on the growth of corn in the Maile 7 (Hydric Dystrendept) soil. But in the oven-dried soil plants were much more healthy and more dry matter yield of corn was produced, compared to the control.
The effect of lime application on N mineralization was studied on the Paaloa (Humoxic Tropohumult) and Wahiawa (Typic Eutrustox) soils in the field. The Paaloa soil had never previously been cultivated or limed. The Wahiawa soil had been limed twice before. Liming at 2 and 4 tons/ ha resulted in greater N mineralization than the control in the Paaloa soil. However, liming from a pH of 4.7 to 7.1 had little effect on the amount of N mineralized in the Wahiawa soil.
An evaluation of the N supplying power of seven soils was made. Two chemical extraction methods as well as aerobic incubation procedures at 25°C and 35°C were used to obtain an index of N availability. Nitrogen mineralized was correlated with N-uptake by corn in the greenhouse. Aerobic incubation at 25°C was significantly correlated (r=0.96) with the N-uptake by corn. Incubation at 35°C was also highly correlated (r=0.92). The chemical methods employed were, by comparison, unsuitable in evaluating the N status of these soils.
The amount of N mineralized from anaerobically-dried sewage sludge when mixed with two soils was very small, and depended on the soil type and the sludge rate. In the Waimea soil (Typic Eutrandept), 3-4% more N was mineralized than in the Wahiawa soil (Humoxic Tropohumult) when the sludge was applied at 22.4 and 44.8 tons/ha rates. N minrealization potential (Nq ) did not adequately predict the actual N mineralized from the soil: sludge mixtures. A two-function equation with two values of N q may be necessary to adequately describe N mineralization in sludge amended soil, because of two different N mineralization rates. One function describes the release of N from a readily-mineralizeable fraction in early incubation (0-4 weeks), while the other function describes the later r e lease of N from the more stable fraction in sewage sludge
Formal Gathering Plus
The goal of this project was to develop an application that would provide assistance for conducting events, seminars or any other type of formal gathering. The initial functional requirements were that at the top level the system administrator would define which persons could conduct an event. Then a record would be made for start / end time, location and subject of event, and who were the participants including their time of arrival and departure.
During the project, a client-server based application was developed. The server was built using a PHP-enabled Apache web server and MySQL database server. The RFID technology was used to recognise the event’s host person and participants. A complete ID-Reader device was made using an RFID reader module and Arduino board. This device passes the IDs of the host and participants to the server and displays acknowledgement to the user regarding the state of the event.
All initial functional requirements were implemented with a few enhancements. There are also a few possibilities highlighted for further development. For example, a web-page for RFID tag allotment to participants, sending notification to the host person and participants regarding an upcoming event, a page for participants’ feedback, and inclusion of an LCD screen in the ID-Reader-Unit for providing more user-friendly acknowledgements

Modelling of Metal-Coating Delamination Incorporating Variable Environmental Parameters
A mathematical model for metal-coat delamination of degrading metal was developed incorporating multiple variable environmental parameters. Metal-coat delamination not only depends on the electrochemical reactions at metal-coat interface but also on the factors like the type of propagating metal ions and their varying concentration with annual weather changes, time of exposure of the coated objects, type of coated objects are stationary or mobile vehicles, frequency with which certain vehicles are operating in various environments e.g. controlled or uncontrolled in terms of environmental conditions. A cutting edge model has been developed to calculate the varying environmental conditions using iteration algorithm, time dependent uncertain position of objects like vehicle in various environments using stochastic approach, effect of seasonal changes on ionic compound's concentration using algebraic method and instantaneous failure probability due to varying conditions. Based on the developed model a detailed simulation study was conducted to investigate the metal-coat delamination process and the ways to regress the under coat metal corrosion
Designing Successful Strategy for Business Process Outsourcing Based on Ontological Knowledge Map
Business process outsourcing (BPO) is an advanced type of IS outsourcing. This study will investigate the obstacles and challenges of BPO Industry. One of the most important problem in this area is identifying existing explicit knowledge and using it to create further knowledge for decision making, so deep investigation on a conceptual model is needed that helps realize the complexities of outsourcing areas especially for business process outsourcing. Most of outsourcing literature has focused on social and cultural impacts and very few tools have been developed to assist manager in making outsourcing decision by modelling the knowledge. In this paper we propose a methodology for modelling the knowledge of a domain in small and medium size enterprises (SMEs). This methodology is based on ontological knowledge map. Findings of this research overcome these obstacles through the use of a formal organizational ontology and knowledge structure maps. The ontology guides decision makers in managing the complexity of outsourcing with holistic approach to the domain of outsourcing. Ontologies as a conceptual model provide a framework to facilitate efficient and effective knowledge-sharing, knowledge reusing and improving communication by modelling the domain of discourse. Keywords: business process outsourcing, ontology, knowledge ma
Development and application of methods for the separation of polyhydroxy compounds
Part I. The complexing of molybdate or tungstate ion with polyhydroxy compounds has been studied with a view to utilizing the complexes for the separation of polyhydroxy compounds. The separation of a large number of polyhydroxy compounds by methods such as anion exchange chromatography, paper chromatography, cellulose column chromatography and thin-layer chromatography, has been described. It has been shown that complex forming polyols possessing four adjacent hydroxyl groups can be separated on molybdate or tungstate forms of anion-exchange resin from the polyols which either do not form a complex or complex due to the presence of 1,2,3-cis,cis triol system. The reason for the non-sorption of the polyols of the latter type on the molybdate or tungstate form of resin has been dicussed.The chromatography on paper partially impregnated with tungstate has divided the polyols into non-complexing polyols, complex forming polyols possessing three adjacent hydroxyl groups and those possessing four adjacent hydroxyl group. The technique of chromatography on paper wholly impregnated with tungstate has, in addition to the separation of a wide variety of substances, further afforded a means of studying the structure of the compounds. Structures for the polyol-tungstate complexes have been suggested and their correlation with the migration rates (on wholly impregnated paper) has been discussed. The mode of complex formation of D-galactose has been studied and the conformation suitable for the formation of D-galactose-tungstate comlex has been proposed. Part II. The preparation of phenylboronates of someacyclic pentitols has been described and the position of hydroxyl group not involved in the ester formation located. Detailed structures of several phenylboronates have been investigated. It has been shown that ribitol and xylitol form 1,3:2,4-bisphenylboronates and 1-deoxy-L-galactitol forms 3,5:4,6-bisphenylboronate. The formation of phenylboronates has been compared with the reaction of aldehydes and ketones with polyols.<p
