    A constant-output atomizer includes a body which has a generally frustoconical expansion nozzle for producing an air jet when a supply of pressurized air is connected to the nozzle upstream of the throat of the nozzle. A liquid feed line supplies liquid to be atomized by the air jet, and the body includes a groove which opens into the diffuser section of the nozzle downstream of the throat for conducting liquid from the feed line to the nozzle. The groove which extends in a direction perpendicular to the axis of the nozzle, and radially with respect to it, has a depth approximately equal to half the axial length of the nozzle. Liquid, conducted by capillary action in the groove to the nozzle, is atomized into a fine mist by the air jet in the nozzle; and the groove eliminates fluctuations in spray order

    Characterization of the transverse relaxation rates in lipid bilayers

    Get PDF
    The 2H NMR transverse relaxation rates of a deuterated phospholipid bilayer reflect slow motions in the bilayer membrane. A study of dimyristoyl lecithin specifically deuterated at several positions of the hydrocarbon chains indicates that these motions are cooperative and are confined to the hydrocarbon chains of the lipid bilayer. However, lipid head group interactions do play an important role in modulating the properties of the cooperative fluctuations of the hydrocarbon chains (director fluctuations), as evidenced by the effects of various lipid additives on the 2H NMR transverse relaxation rates of the dimyristoyl lecithin bilayer

Kind of burn that often happen is superficial partial thickness burn, which is people choose to do some self medication because the expense is relatively high. The content of alliin in onion (Allium sativum L) be trusted can be used to help healing process of superficial partial thickness burn, with its biology activity as anti-agregation of platelet cells, fibrinolysis accelerator, and anti-bacterial. Aims : To find out the effect of onion extract (Allium sativum L) in superficial partial thickness burn. Method : A post test only control group design study with 4 groups which divided into two categories consist of control group and treatment group. the control group is rats that been given superficial partial thickness burn without any preferential treatment and treatment groups are hordes of rats that been given superficial partial thickness burn which divided into 3 group then each group smeared with onion extract 1.5%, 3.0%, and 6.0%. The assessment is conducted in 14 days using Bates Jensen Wound Assessment Tool. Result : Subjects in control group, superficial partial thickness burn without any treatment reach its recovery in 14 days. Subjects with superficial atrial thickness burn smeared with onion extract 1.5% reach its recovery in 10 days ,with onion extract 3.0% in 11days , and onion extract 6.0% in 12 days. Conclusion : There is an effect that can be found in onion extract with 1.5%, 3.0%, and 6.0% concentration that smeared on superficial partial thickness burn Key Words : Burn injury, superficial atrial thickness burn, onion, Allium sativum L

    S-Mbank: Secure Mobile Banking Authentication Scheme Using Signcryption, Pair Based Text Authentication, and Contactless Smartcard

    Nowadays, mobile banking becomes a popular tool which consumers can conduct financial transactions such as shopping, monitoring accounts balance, transferring funds and other payments. Consumers dependency on mobile needs, make people take a little bit more interest in mobile banking. The use of the one-time password which is sent to the user mobile phone by short message service (SMS) is a vulnerability which we want to solve with proposing a new scheme called S-Mbank. We replace the authentication using the one-time password with the contactless smart card to prevent attackers to use the unencrypted message which is sent to the user's mobile phone. Moreover, it deals vulnerability of spoofer to send an SMS pretending as a bank's server. The contactless smart card is proposed because of its flexibility and security which easier to bring in our wallet than the common passcode generators. The replacement of SMS-based authentication with contactless smart card removes the vulnerability of unauthorized users to act as a legitimate user to exploit the mobile banking user's account. Besides that, we use public-private key pair and PIN to provide two factors authentication and mutual authentication. We use signcryption scheme to provide the efficiency of the computation. Pair based text authentication is also proposed for the login process as a solution to shoulder-surfing attack. We use Scyther tool to analyze the security of authentication protocol in S-Mbank scheme. From the proposed scheme, we are able to provide more security protection for mobile banking service.Comment: 6 page

    Inflation Targeting Framework (ITF) is a monetary policy framework that is characterized by the public announcement of the inflation target to be achieved. This research aims to compare the effects of macroeconomics variable to the implementation of Inflation Targeting Framework (ITF) in Indonesia and Thailand in 2007-2011. The research used granger causality test, cointegration, and Vector Error Correction Model (VECM) data analysis method in which outlines the impulse response and Forecasting Error Variance Decomposition; both properties of the VECM. The analysis in this research used the time series data from 2007:1 until 2011:10, obtained from the International Financial Statistic (IFS) by IMF. Results indicated that Indonesia's long-term interest rates and the exchange rate of a significant negative effect while the money is a positive significant effect. Another case in Thailand, the exchange rate and the money significantly positive while the interest rate a significant negative effect. Effect of short-term Inflation Targeting in Indonesia is influenced by interest rates. While in Thailand affected by three variables: inflation itself, interest rates and exchange rates. Monetary authority needs to make communication between monetary policy with other macroeconomic policies, so that the formation of inflation expectations of economic agents and the achievement of short-term inflation can be more focused on long-term targets.Keywords : Inflation Targeting, Macroeconomic variable, Causality, VECM Inflation Targeting Framework (ITF) merupakan sebuah kerangka kebijakan moneter yang ditandai dengan pengumuman kepada publik mengenai target inflasi yang akan dicapai.Penelitian ini bertujuan untuk membandingkan pengaruh variabel makroekonomi terhadap penerapan inflation targeting framework (ITF) di negara Indonesia dan Thailand pada periode 2007 – 2011.Metode penelitian menggunakan analisis data granger causality, cointegration test, dan Vector Error Correction Model (VECM) yang didalamnya menguraikan fungsi impulse response dan Forecasting Error Variance Decomposition yang merupakan properti dari model VECM . Analisis dalam penelitian ini menggunakan data time series 2007:1 hingga 2011:10 yang diperoleh dari International Financial Statistic (IFS) dari IMF. Dari hasil analisis VECM menunjukkan di Indonesia dalam jangka panjang suku bunga dan nilai tukar berpengaruh signifikan negatif sedangkan jumlah uang beredar berpengaruh signifikan positif. Lain halnya di Thailand, nilai tukar dan jumlah uang beredar berpengaruh signifikan positif sedangkan suku bunga berpengaruh signifikan negatif. Pengaruh Inflation Targeting jangka pendek di Indonesia dipengaruhi oleh tingkat suku bunga. Sedangkan di Thailand dipengaruhi oleh tiga variabel yaitu inflasi itu sendiri, suku bunga dan nilai tukar. Otoritas moneter perlu melakukan komunikasi antara kebijakan moneter dengan kebijakan makro lainnya, agar pembentukan ekspektasi inflasi dari agen ekonomi dan pencapaian inflasi jangka pendek dapat lebih terarah pada target jangka panjangnya Kata kunci : Inflation Targeting, Variabel Makroekonomi Kausalitas, VEC
