<p>Peningkatan sifat fungsional pati dapat dilakukan dengan mengubah struktur pati menjadi lebih banyak pada bagian amorf dengan cara perlakuan fermentasi pada umbi singkong terlebih dahulu sehingga dihasilkan Mocaf. Tujuan penelitian ini adalah untuk mengetahui perubahan karakteristik pati Mocaf dengan perlakuan panas dan pengaturan tingkat keasaman (pH) agar dapat digunaan dalam aplikasi yang lebih luas. Perlakuan dalam penelitian ini meliputi variasi suhu pemanasan (60, 70, 80, 90, dan 120 °C) dan pH (3, 4, 5, 6, dan 7) dan diulang sebanyak 3 kali dengan parameter pengukuran meliputi daya kembang, kelarutan, kekeruhan, viskositas pasta, bentuk granula pati, dan sineresis. Hasil penelitian ini menunjukkan bahwa suhu pemanasan mempengaruhi nilai daya kembang, kelarutan, viskositas, bentuk granula pati, dan sineresis Mocaf, tetapi menyebabkan penurunan tingkat kekeruhan. Sedangkan penambahan asam dapat mempengaruhi viskositas dan granula pati Mocaf.</p><p> </p><p><strong>Effect of pH and Temperature Treatment on Physicochemical Properties of Mocaf (Modiffied Cassava Flour) </strong></p><p>The changes in the starch’s structure to amorphous can increase the functional characteristics of starch using the fermentation process of cassava to be known as Mocaf. The aim of this study was to determine the physicochemical properties of Mocaf’s starch due to temperature and pH processing. Treatment in this research including various of temperature (60, 70, 80, 90, and 120 °C) dan pH (3, 4, 5, 6, dan 7) in three replications with analysis of swelling power, solubility, viscosity, starch granule, and syneresis. The results of this study indicate that the heating temperature affects the value of swelling power, solubility, viscosity, starch granule, and syneresis of Mocaf, but it causes a decrease of Mocaf’s turbidity. The addition of acid may affect the viscosity and granules of Mocaf’s starch.</p>

In a study of the properties of a Ta-Au metallization system for thin film technology application, the interdiffusion between Ta(bcc)-Au, βTa-Au and Ta2M-Au films was studied. Considered here is a discussion of the use of the transmission electron microscope(TEM) in the identification of phases formed and characterization of the film microstructures before and after annealing.The films were deposited by sputtering onto silicon wafers with 5000 Å of thermally grown oxide. The film thicknesses were 2000 Å of Ta and 2000 Å of Au. Samples for TEM observation were prepared by ultrasonically cutting 3mm disks from the wafers. The disks were first chemically etched from the silicon side using a HNO3 :HF(19:5) solution followed by ion milling to perforation of the Au side.

This paper deals with [V V] dvandva compounds, which are frequently used in East and Southeast Asian languages but also in Greek and its dialects: Greek is in this respect uncommon among Indo-European languages. It examines the appearance of this type of compounding in Greek by tracing its development in the late Medieval period, and detects a high rate of productivity in most Modern Greek dialects. It argues that the emergence of the [V V] dvandva pattern is not due to areal pressure or to a language-contact situation, but it is induced by a language internal change. It associates this change with the rise of productivity of compounding in general, and the expansion of verbal compounds in particular. It also suggests that the change contributes to making the compound-formation patterns of the language more uniform and systematic. Claims and proposals are illustrated with data from Standard Modern Greek and its dialects. It is shown that dialectal evidence is crucial for the study of the rise and productivity of [V V] dvandva compounds, since changes are not usually portrayed in the standard language.

Free Energy Of Mixing

The observed asymmetric behaviour of mixing of  NaCd liquid alloys around equiatomic composition with smaller negative values for free energy of mixing at compound forming concentration, i.e. GMXS = -4.9KJ at Ccd =0.66 has  aroused our interest to undertake a theoretical investigation of this system.A simple statistical mechanical theory based on compound formation model has been used to investigate the energetics of formation of intermetallic compound Cd2Na in the melt through the study of entropy of mixing.Besides, the interionic interactions between component atoms Na and Cd of the alloys have been understood through the study of interionic pair potential фij(r), calculated from pseudopotential theory in the light of CF model.Our study of фij(r) suggest that the effective interaction between Na-Na atoms decreases on alloying with Cd atom, being minimum for compound forming alloy( Cd 0.66 Na 0.34 ).The nearest neighbor distance between Na-Na atoms does not alter on alloying. Like wise Na-Na,  effective interaction between  Cd-Cd atom decreases from pure state to NaCd alloys, being smaller at compound forming  concentration Cd 0.66 Na 0.34.The computed values of SM from pseudopotential theory are positive at all concentrations, but the agreement between theory and experimental is not satisfactory. This might be happening due to parameterisation of σ3 and Ψcompound.

The study aims to use an adsorbent natural based of Moroccan oil shale of Timahdit area (Y layer) in a physical-chemical adsorption process for treating industrial discharges colorful. The used adsorbent is the insoluble party of the sub-critical extraction of decarbonized oil shale of Timahdit. The tests performed on the methylene blue (MB), showed a strong elimination in the first 10 minutes. The influences of various experimental parameters were studied: mass ratio of adsorbent, time and temperature of thermal treatment, contact time, pH of MB and heating temperature of solution on the parameters of material were studied. The experimental results have shown that the adsorption of methylene blue dye by the adsorbent is more than 90% at initial pH a range 6-7 at room temperature for 30 minutes. The process is simple and the adsorbent produced is a new material with interesting adsorption capacities of moderate cost which does not require an activating agent and can be used as industrial adsorbent for the decontamination of effluents containing organic pollutants.
