Effect of Marine Environment to the Concrete Beams Strengthened Using GFRP Sheet
Structures built aggresive enviroment such ason the sea/marine environment is to be carefully designed, due to possibility of chloride ion penetration into the the concrete. One way to reduce the strength degradation in such environment is to use FRP, which is attached to the surface of R/C using epoxy. The study presented is focused on determining the effect of the sea water to the capacity of GFRP as flexural reinforcementelements. Beam of 10x10x40 cm dimension were designed without reinforcing bars. The samples were tested using variation to the distance to the sea and duration of the contact to sea.\ud
The result showed that the use GFRP increased the flexural strength 84,21%, compared to the normal beam, without GFRP. It can also be seen that the closer the distance to the sea, the higher the strength degradation of the beam. The sample rinsed in the water has strength 2.53 kN. The result of this study also showed that for areas closer to the sea has a greater effect in terms decreasing flexural capacity of the bea

All laboratory prameters were normal except an unconjugated hyperbilirubinemia. A diagnosis of Gilbert syndrome was made after careful clinical evaluation.CONCLUSION: Recognizing Gilbert syndrome has important clinical implicaitions by avoiding uncessary and expensive workup of patients with jaundice. Mangement entails avoiding stressful conditions and prolonged fasting. 
Frequency of cerebrovascular accidents and brain abscess in childrens with tetralogy of fallot Dr.
OBJECTIVE: To determine the frequency of cerebrovascular accidents and brain abscess in children of Tetralogy of Fallot presented with neurological manifestations.
PATIENTS AND METHODS: It was a cross-sectional descriptive observational study done at the Pediatric Cardiology and Pediatric Neurology departments of The Childrenâs Hospital & Institute of Child Health, Lahore from Dec 2009 to Nov 2010. A total 75 patients of Tetralogy of Fallot (TOF) up to the age of 15 years with neurological manifestation meeting the inclusion criteria were enrolled in this study. CT brain with contrast was conducted in all patients to look for evidence of cerebrovascular accident (stroke) and/or brain abscess.
RESULTS: Out of total 75 patients of Tetralogy of Fallot (TOF) presented with neurological manifestation 48 (64%) were having brain abscess, 24 (32%) were having cerebrovascular accident (CVA), 2 (2.6%) were having intracranial bleed and 1 (1.3%) was having meningoencephlitis. Disease breakdown according to age showed increasing frequency of brain abscess as age increases with maximum cases above 10 years of age. However maximum cases of CVA reported in patients below age of 2years.
CONCLUSION: Brain abscess have found to be more frequent than cerebrovascular accidents in patients with tetralogy of fallot. Therefore, we should have a high index of suspicion of brain abscess in every unoperated patient of tetralogy of fallot presenting with neurological manifestation

EFEK PENAMBAHAN SERAT POLYPROPYLENE TERHADAP KUAT TEKAN BETON PADA PERKERASAN KAKU
Rigid pavement or cement concrete pavement is a construction (pavement) with aggregate and raw materials and uses cement as a binding material. Rigid pavements have good compressive strength, but in contrast to flexural strength, this is due to their brittle nature, so when planning rigid pavements, fiber is added to the concrete mixture in the hope of increasing the elastic or flexible properties of the rigid pavement itself. This study aims to analyze the effect of adding polypropylene fibers to a mixture of rigid pavement concrete with a variation of 0.1%; 0.3%; 0.5%; 0.7%; and 1.0% by weight of cement. Control test objects without using polypropylene fiber. The number of cylindrical specimens of 15x30 cm was 30 pieces. Compressive strength test. The results showed that the compressive strength were optimum at 0.30%.Perkerasan kaku atau perkerasan beton semen adalah konstruksi (perkerasan jalan) dengan agregat dan bahan baku serta menggunakan semen sebagai bahan pengikat. Perkerasan kaku memiliki kuat tekan yang baik, namun berbeda dengan kuat lentur, hal ini dikarenakan sifatnya yang getas, sehingga pada saat merencanakan perkerasan kaku, ditambahkan serat pada campuran beton dengan harapan dapat meningkatkan sifat elastis atau lentur dari perkerasan kaku itu sendiri. Penelitian ini bertujuan menganalisis pengaruh penambahan serat polypropylene pada campuran beton perkerasan kaku dengan variasi 0,1%; 0,3%; 0,5%; 0,7%; dan 1,0% berat semen.

KORELASI POROSITAS BETON TERHADAP KUAT TEKAN RATA-RATA
Agregat yang tersedia di alam umumnya mempunyai pori yang berbeda setiap satu lokasi, hal ini dapat dilihat dengan perbedaan nilai resapan air oleh agregat. Salah satu masalah yang dihadapi adalah bagaimana pengaruh porositas terhadap nilai kuat tekan beton, dengan perbedaan nilai faktor air semen (FAS).Tujuan penelitian ini adalah untuk mengetahui hubungan dan pengaruh porositas beton dengan kuat tekan beton rata-rata. Pada penelitian ini dilakukan pengujian kuat tekan dan porositas beton. Penelitian ini menggunakan agregat kasar dari 3 lokasi yaitu Tubo, Bula, dan Togafo. Pembuatan benda uji dengan nilai FAS berbeda.Dari hasil penelitian disimpulkan bahwa semakin besar porositas maka kuat tekan beton semakin kecil. Dari hasil analisa regresi diperoleh nilai koefesien korelasi yaitu negatif, maka kedua variabel mempunyai hubungan tidak searah. Hubungan antara porositas agregat terhadap kuat tekan beton sangat kuat, hal ini dilihat dari hasil analisis data yang menunjukkan nilai korelasi atau hubungan antara dua variabel sangat erat

Economic Development in Extreme Environments
The role of the environment in the development process is frequently framed as a one-way interaction, with humans decoupling from natural systems, and often damaging them in the process. When the environment is granted an influential role, it is often in establishing the initial conditions under which development will take place, for example, through natural resource endowments or climate factors. However, in some extreme environments, it may be responsible for not only the initial opportunities available in a society, but also for continuously shaping those opportunities through time. The field of Sustainable Development is fundamentally concerned with this two-way interaction between the environment and society, recognizing both as part of a coupled system. The chapters in this volume demonstrate some of the costs associated with development in an extreme environment using methods from climate science, ecology, remote sensing, and economics. By looking at places exposed to tropical cyclones, to persistent pollution resulting from fires that burn readily in a drought-prone location, to annual floods that frequently and randomly strike households in a country, we see that the environment critically shapes aspects of societies and their economic opportunities. By no means are all opportunities dictated by the environment. However, these chapters robustly illustrate that the environment imposes some critical boundaries on development in extreme environments and policies aiming to increase welfare must take account of the coupling of social and natural systems
