<p>Penelitian ini bertujuan untuk melihat keeratan hubungan antara frekuensi terpaan informasi melalui media komunikasi dengan perilaku masyarakat tentang bencana gempa dan tsunami. Media komunikasi dibedakan menjadi dua yaitu saluran komunikasi pribadi (personal Communication Channel) dan saluran komunikasi non pribadi (non personal communication channel). Sedangkan perilaku dibagi kepada 3 domain/ranah yaitu, ranah kognitif, ranah afektif, dan ranah psikomotor. Penelitian ini merupakan penelitian survei dengan pendekatan kuantitatif. Teknik analisis data menggunakan analisis korelasi Somers'd. Hasil penelitian menunjukkan, bahwa frekuensi masyarakat diterpa oleh media atau saluran komunikasi personal dan media atau saluran komunikasi non personal masuk dalam kategori jarang. Tingkat kognitif mayoritas masyarakat tentang gempa bumi dan tsunami masuk dalam kategori tinggi, tingkat afektif dan psikomotorik mayoritas masyarakat masuk dalam kategori sangat tinggi. Hasil analisis korelasi yang diperoleh adalah media atau saluran komunikasi non personal (media massa) berhubungan signifikan negatif dengan kognitif dan afektif masyarakat tentang gempa bumi dan tsunami. Artinya, semakin sering masyarakat memperoleh informasi tentang bencana gempa bumi dan tsunami melalui media komunikasi non personal (media massa) maka semakin rendah tingkat kognitif dan afektif masyarakat atau sebaliknya.</p><p><strong><em>Kata kunci</em></strong><em>: Media Komunikasi, Perilaku, Bencana, Gempa Bumi dan Tsunami</em></p>

Daunomycin, an antibiotic used in the clinical management of acute leukemia, produces a delayed, lethal cardiac toxicity. The lethality is dose and schedule dependent; histopathologic changes induced by the drug have been described in heart, lung, and kidney from hamsters in both single and multiple dose studies. Mice given a single intravenous dose of daunomycin (10 mg/kg) die 6-7 days later. Drug distribution studies indicate that the rodents excrete most of a single dose of the drug as daunomycin and metabolite within 48 hours after dosage (M. A. Asbell, personal communication).Myocardium from the ventricles of 6 moribund BDF1 mice which had received a single intravenous dose of daunomycin (10 mg/kg), and from controls dosed with physiologic saline, was fixed in glutaraldehyde and prepared for electron microscopy.

Imaging Device

An (electron) microscope can be considered as a communication channel that transfers structural information between an object and an observer. In electron microscopy this information is carried by electrons. According to the theory of Shannon the maximal information rate (or capacity) of a communication channel is given by C = B log2 (1 + S/N) bits/sec., where B is the band width, and S and N the average signal power, respectively noise power at the output. We will now apply to study the information transfer in an electron microscope. For simplicity we will assume the object and the image to be onedimensional (the results can straightforwardly be generalized). An imaging device can be characterized by its transfer function, which describes the magnitude with which a spatial frequency g is transferred through the device, n is the noise. Usually, the resolution of the instrument ᑭ is defined from the cut-off 1/ᑭ beyond which no spadal information is transferred.

Abstract. This quasi-experimental study examined the effects of exposure to a computer game on arousal and subsequent task performance. After inducing a state of low arousal, participants were assigned to experimental or control conditions via self-selection. Members of the experimental group played a computer game for five minutes; subjects in the control group spent the same amount of time awaiting further instructions. Participants who were exposed to the computer game showed significantly higher levels of arousal and performed significantly better on a subsequent cognitive task. The pattern of results was not influenced by the participants' prior experience with the game. The findings indicate that mood-management processes associated with personal media use at the workplace go beyond the alteration of arousal and affect subsequent cognitive performance.

Activation Peptides

Bovine Factor X is eluted in two forms (X1and X2) from anion exchange chromatographic columns. These two forms have indistinguishable amino acid compositions, molecular weights and specific activities. The amino acid sequences containing the γ-carboxyglutamic acid residues have been shown to be identical in X1 and X2(H. Morris, personal communication). An activation peptide is released from the N-terminal region of the heavy chain of Factor X by an activator from Russell’s viper venom. This peptide can be isolated after activation by gel filtration on Sephadex G-100 under nondenaturing conditions. The activation peptides from a mixture of Factors X1 and X2 were separated into two forms by anion-exchange chromatography. The activation peptide (AP1) which eluted first was shown to be derived from Factor X1. while the activation peptiae (AP2) which eluted second was shown to be derived from X2 on the basis of chromatographic separations carried out on Factors X1 and X2 separately. Factor Xa was eluted as a symmetrical single peak. On the basis of these and other data characterizing these products, we conclude that the difference between X1 and X2 are properties of the structures of the activation peptides.

A Priori Uncertainty

This paper is devoted to the presence of distortions in a speech signal transmitted over a communication channel to a biometric system during voice-based remote identification. We propose to preliminary correct the frequency spectrum of the received signal based on the pre-distortion principle. Taking into account a priori uncertainty, a new information indicator of speech signal distortions and a method for measuring it in conditions of small samples of observations are proposed. An example of fast practical implementation of the method based on a parametric spectral analysis algorithm is considered. Experimental results of our approach are provided for three different versions of communication channel. It is shown that the usage of the proposed method makes it possible to transform the initially distorted speech signal into compliance on the registered voice template by using acceptable information discrimination criterion. It is demonstrated that our approach may be used in existing biometric systems and technologies of speaker identification.

Political Songs

Today there are hundreds of papers published on the problem of labor migration from Central Asian countries, its political, social and economic aspects, as well as on the problem of integration and adaptation of migrants in the Russian society. However, the topic of migrant poetry is still poorly studied in Russia. At least there is no such research on Tajik labor migrants. The genres of Tajik migrant poetry vary significantly and include such forms as love poems, political songs, songs about migration hardships, religious poems. This paper is based on the results of monitoring social networks «Odnoklassniki», «Facebook», as well as on the results of personal communication and interviews with poets. In the paper we use the poems of three authors written in Tajik, Russian and Shugnani languages. The semantic translation from Tajik and Shugnani was done by the author of this paper
