The results of the effect of lighting on the piezoelectric characteristics of quartz resonators in the form of a tuning fork, which have been pre-trained by increased friction from the external environment, are presented. A significant change in the piezoelectric characteristics of such resonators was found depending on the intensity and spectrum of illumination. It is assumed that the detected change in the characteristics of the resonators is due to dislocations formed in the resonator during training with increased friction of the external environment, and is a manifestation of the well-known photoplastic effect and its quenching.

Microprobe analysis of biological tissue is now in the end phase of transition from instrumental and technique development to applications pertinent to questions of physiological relevance. The promise,implicit in early investigative efforts, is being fulfilled to an extent much greater than many had predicted. It would thus seem appropriate to briefly report studies exemplifying this, ∿. In general, the distributions of ions in tissue in a preselected physiological state produced by variations in the external environment is of importance in elucidating the mechanisms of exchange and regulation of these ions.

Periplasm of bacteria is the space outside the permeability barrier of plasma membrane but enclosed by the cell wall. The contents of this special milieu exterior could be regulated by the plasma membrane from the internal, and by the cell wall from the external environment of the cell. Unlike the gram-negative organism, the presence of this space in gram-positive bacteria is still controversial because it cannot be clearly demonstrated. We have shown the importance of some periplasmic bodies in the secretion of penicillinase from Bacillus licheniformis.In negatively stained specimens prepared by a modified technique (Figs. 1 and 2), periplasmic space (PS) contained two kinds of structures: (i) fibrils (F, 100 Å) running perpendicular to the cell wall from the protoplast and (ii) an array of vesicles of various sizes (V), which seem to have evaginated from the protoplast.

Summaryɛ(γ-glutamyl)lysine isodipeptide has been detected in normal human plasma by a sensitive HPLC technique in a concentration of 1.9-3.6 μmol/1. Incubation of in vitro clotted plasma at 37° C for 12 h resulted in an increased amount of isodipeptide, and there was no further significant change when streptokinase was also present. Increased in vivo isodipeptide concentrations were also observed in hypercoagulable states and during fibrinolytic therapy.

SummaryDuring “spontaneous” activation of a human euglobulin preparation in suitably spaced samples — while plasminogen became progressively converted into piasmin — the proactivator content was tested by addition of equal amounts of streptokinase and evaluation of the lytic activities on heated and normal bovine fibrin plates. Indepedently of the decreasing content of plasminogen the proactivator which could be activated by streptokinase showed no significant change of concentration. These observation indicate that plasminogen is not acting as proactivator and that there exists a separate proactivator-activator system of the fibrinolytic mechanism in human serum.

This paper shows the diversity and significance of relations of duality among different economic systems. The composition of the principles underlying the system economic theory used for the analysis of duality in the economy is investigated. The concept of the economic system is clarified and the equivalence of three basic concepts of the economic system is shown: a) as a space-time volume (“black box”); b) as a complex of elements and connections among them; c) as a tetrad, including object, project, process and environment components. In a new way, the concept of the tetrad is revealed. The actual interpretation of the interrelationships of its components, based on the mechanisms of intersystem circulation of spatial and temporal resources and the transmission of abilities from one economic system to another, is proposed. On the basis of the obtained results, the most essential aspects of duality in the theory of economic systems are considered. It is shown that the interaction of internal content and the nearest external environment of economic systems lies in the nature of the relations of duality. A new approach to modeling the structure and to functioning of the economic system, based on the description of its activities in the form of two interconnected tetrads (the first tetrad reflects the intrasystem production cycle and the second one — the external realization-reproduction cycle) is put forward. It is shown that the concept of duality in a system economy creates prerequisites for adapting the functioning of local economic systems (objects, projects, etc.) in a market, administrative and functional environments and, as a result, harmonizing the economy as a whole.

Based on the results of the analysis of the ratio of the financial statements can be seen from liquidity ratio in 2010 can already be said to be liquid and in 2011 occurred very significant increase in this ratio that makes the company's liquidity to be too high. Judging from the solvency ratio, in 2010 the company could not be said solvable because the value of this ratio is still quite high. However, in 2011 this ratio decreased significantly which shows that the company can already be said to be solvable. From the ratio of the activity, in 2010 and 2011 the ratio of corporate activity can already be said to be good. Despite the decrease from 2010 to 2011 on some of these ratios, but the overall ratio of activity of the company is good enough. Judging from the ratio of profitability, in 2010 and 2011 the profitability of the company can not be said to be good because it is still very low and no significant change from the year 2010 to the year 2011 for this ratio.The overall financial performance of PT Mekar Karya Pratama from year 2010 to year 2011 can be said to be good, although there are some things that must be considered and they should be repaired as liquidity is too high which causes the idle funds and the impact on the profitability is low.

The analysis presented here offers a possible framework for understanding when sub-state actors behave prudently and more strategically in their foreign relations, and when other priorities might instead heighten the chances of seemingly irrational, erratic, or dangerous, foreign policies. Using a case study of the Kurdistan Regional Government of Iraq to illustrate the argument, the author attempts to show how “regime consolidation” plays a key role in allowing such actors to prioritise policies aimed at grappling with external challenges, threats and opportunities. Internally legitimate, consolidated regimes can better present “one face” to the outside world and behave more strategically in the international arena.  Political systems lacking consolidation or internal legitimacy, in contrast, turn to the external environment in search of resources to help them with domestic threats and challenges. This may lead to seemingly erratic, unpredictable and risky foreign policies on their part. Abstract in Kurmanji Aktorên bin-dewletî û girtina rîskên siyaseta derve: Hikûmeta Herêma Kurdistanê ya Iraqê Analîza ku li vir hatiye pêşkêşkirin çarçoveyeke muhtemel ji bo fehmkirina demên ku aktorên bin-dewletî di têkiliyên xwe yên derve de bi hişyarî û stratejîk tevdigerin û demên di dewsê de pêşkiyên din şansên siyaseta derve yên xeternak, guherbar û îrrasyonel didine ber xwe. Bi bikaranîna mînaka Hikûmeta Herêma Kurdistanê ya Iraqê nivîskar hewl dide ku nîşan bide ka çawa “xurtkirina rejîmê” roleke serekî dilîze di destûrdana van aktoran de ku pêşekiyê bidin polîtîkayên ku bi dijwarî, tehdît û talûkeyên derve bigre. Rejîmên di hundir de meşrû û xurt dikarin baştir “rûyekî” nîşanê cîhana derve bidin û di qada navneteweyî de bêhtir stratejîk tevbigerin. Lê belê sîstemên siyasî yên ne xurt û di hundir de ne meşrû jî berê xwe didin derdora derve di lêgerîna çavkaniyan de da ku alîkariya wan bikin ji bo talûke û zehmetiyên hundirîn. Ev dikare bibe sedem ku ew polîtîkayên derveyî yên birîsk, netexmînbar û hevnegir ên berçav bigrin ji aliyê xwe ve.
