Judul: Evaluasi Radiografi Toraks Anak Babi (Sus scrofa) sebagai Hewan Model dalam Manuver Rekrutmen Cedera Paru Akut Pediatri.
Abstrak: Studi dilakukan untuk menganalisis perubahan pada paru-paru manuver rekrutmen anak babi yang diinduksi cedera paru akut (CPA) sebelum manuver rekrutmen (praperlakuan) dan setelah manuver rekrutmen (pascamanuver). Ada sepuluh ekor anak babi diinduksi CPA dengan melakukan kumbah bronkus menggunakan NaCl 0.9%. Anak babi dibagi menjadi dua kelompok, kelompok pertama dilakukan manuver rekrutmen tanpa pembebatan di dada (nonbebat) dan kelompok kedua dilakukan manuver rekrutmen dengan pembebatan di dada (bebat). Hasil menunjukkan pada kedua kelompok perlakuan ditemukan perubahan radiografi yaitu pola intertsisial berupa peribronchial pattern, pola alveolar berupa cotton-like density, air bronchogram, edema pulmonum dengan tipe nonkardiogenik dan tidak ditemukannya gambaran dilatasi vena pulmonalis. Gambaran perubahan antara kelompok bebat dengan nonbebat tidak ada perbedaan.

Judul: Interpretasi Radiografi Jantung Anak Babi (Sus Scrofa) pada Manuver Rekrutmen Cedera Paru Akut Pediatri
Abstrak: This study was conducted to evaluate cardiovascular radiography (vertebrae heart score (VHS) and cardiothoracic ratio (CTR)) during recruitment maneuver after induced acute lung injury (ALI) in piglet as animal model. As many as ten piglets used on this study. Condition of ALI were induced by lavaging prewarmed saline into lung parenchymal. Recruitment maneuver performed into two groups. The first group (RmB) was bandaged on their chest during recruitment maneuver while the second group (Rm) was not. Chest bandaging is simulated abnormalities of diaphragm muscle in baby. Samples were taken before and after recruitment maneuver. On right lateral view showed that, angle of heart value were ranged between 28.28-34.83o and VHS value increase in RmB greater than Rm. This is happened because chest bandaging provided additional intrathoracic pressure. On Dorsoventral view, CTR value between groups still in the normal range. RmB as a model pediatric musculoskeletal disorders showed significant disturbance in right heart has showed increase short axis value. Rm showed no significant abnormalities. Intrathoracic pressure agreeged heart contractility by enlarging right heart chamber during recruitment maneuver.

Judul: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
