Sprawa operacyjnego sprawdzenia kryptonim „Zakonnik”. Inwigilacja ks. Henryka Surmy przez Służbę Bezpieczeństwa w latach 1974-1977
Authors: Szymański Andrzej
Published: December 2018

Celem opracowania jest ukazanie na przykładzie jednego z zakonników sposobu postępowania Służby Bezpieczeństwa wobec duchownych, którzy znaleźli się w spektrum zainteresowania tej instytucji, z uwagi na podejrzenie prowadzenia „antypaństwowej” działalności. Tego rodzaju sprawy operacyjnego sprawdzenia zakładane były przez Służbę Bezpieczeństwa PRL bardzo często i miały na celu sprawdzenie doniesień o prowadzeniu przez duchownych działalności uznawanej przez władze komunistyczne za wrogą ustrojowi PRL. Ks. Henryk Surma, nie godząc się na komunistyczne ograniczenia praw człowieka, ani na dążenia władz PRL zmierzające do marginalizacji Kościoła, próbował na własną rękę pozyskać środki na remont kościoła parafialnego, wykorzystując przy tym swoje prywatne kontakty z obywatelami RFN. Podejrzany o działania antypaństwowe, poddany został przez funkcjonariuszy Służby Bezpieczeństwa wszechstronnej kontroli i naciskom. Ostatecznie inwigilację zakończono po kilku latach, nie udowodniwszy duchownemu działania na szkodę PRL. Akta sprawy pokazują, że ks. Surma był dobrym duszpasterzem, który za swe zaangażowanie zapłacił zainteresowaniem ze strony Służby Bezpieczeństwa. Artykuł oparty został na materiałach archiwalnych zgromadzonych w Archiwum Instytutu Pamięci Narodowej.
Zaświadczenie o braku okoliczności wyłączających zawarcie małżeństwa w procedurze matrimonium per procura
Authors: Świto Lucjan , Tomkiewicz Małgorzata
Published: December 2018

Artykuł prezentuje rozwiązania normatywne dotyczące procedury wystawiania, treści i znaczenia zaświadczenia o braku okoliczności wyłączających zawarcie małżeństwa, w kontekście regulacji związanych z zawieraniem małżeństwa przez pełnomocnika (matrimonium per procura). Zasadniczy cel i problem badawczy zawarty w publikacji oscyluje wokół odpowiedzi na pytanie, o braku jakich konkretnie okoliczności, dokument ten informuje; czy mechanizmy kontrolne towarzyszące wystawieniu tego zaświadczenia obejmują wymogi określone w art. 6 § 1 k.r.o. i czy dostrzegają specyfikę małżeństwa zawieranego przez pełnomocnika? Co konkretnie oznacza użyte w art. 8 § 1 k.r.o. sformułowanie, iż duchowny „nie może przyjąć oświadczeń przewidzianych w art. 1 § 2 [k.r.o.]” bez uprzedniego przedstawienia mu omawianego zaświadczenia i czy wskazany w tym przepisie zakaz dowodzi, że zaświadczenie o braku okoliczności wyłączających zawarcie małżeństwa ma charakter konstytutywny?

Artykuł stawia tezę, że o ile sama idea wystawiania omawianego zaświadczenia jest bez wątpienia słuszna, o tyle dostosowywanie przepisów k.r.o. i p.a.s.c. do Konkordatu poszło w omawianej materii za daleko. Skutkowało ono wprowadzeniem takich obostrzeń, które statuują wyraźny prymat formalizmu nad zasadą favor matrimonii i dają asumpt do zróżnicowanej oceny charakteru tego zaświadczenia, w tym do formułowania tez o konstytutywnym charakterze tego dokumentu. Dla osób zamierzających zawrzeć małżeństwo w formie wyznaniowej ze skutkami cywilnymi wymóg legitymowania się zaświadczeniem mającym moc prawną stał się przesłanką w zasadzie analogiczną do tej, jaką mają inne, konstytutywne przesłanki małżeństwa, przy czym obostrzenie to nie ma charakteru powszechnego. Nie dotyczy ono nupturientów zamierzających zawrzeć małżeństwo przed kierownikiem USC lub konsulem (art. 1 §§ 1 i 4 k.r.o) a odnosi się tylko do tych, którzy zamierzają zawrzeć małżeństwo w formie wyznaniowej ze skutkami cywilnymi. Istniejący stan rzeczy trudno uznać za właściwy. Mankamentem obowiązujących regulacji jest również to, że zaświadczenie o braku okoliczności wykluczających zawarcie małżeństwa, mimo, iż zyskało znaczenie nieproporcjonalne do swej roli, „nie rozpoznaje” specyfiki małżeństw wyznaniowych ze skutkami cywilnymi zawieranymi per procura i w tym przypadku funkcji gwarancyjnych w należytym stopniu nie spełnia.
Srednjovjekovni itinerar po Svetoj zemlji iz Vinodolskoga zbornika
Authors: Vučković Josip
Published: December 2018

U članku se objavljuju prva povijesna i književnopovijesna analiza te transliteracija kasnosrednjovjekovnoga teksta ot er(u)s(o)l(i)ma i groba b(o)žiê čt(enie) koji je zapisan u Vinodolskom zborniku (Zagreb: Arhiv HAZU, sign. III a 15). Posrijedi je jedini zasad poznati hrvatski srednjovjekovni itinerar po Svetoj zemlji, koji je vjerojatno bio sastavljen na temelju nepoznata latinskoga ili romanskoga teksta. Obrazlaže se hipoteza prema kojoj hrvatskoglagoljski itinerar nije bio zamišljen kao praktičan hodočasnički vodič, nego kao poučan tekst namijenjen učvršćivanju »kolektivnoga pamćenja« o Svetoj zemlji kao prostoru na koji kršćani imaju isključivo pravo. Osim toga, iznosi se hipoteza da je hrvatskoglagoljski itinerar mogao biti namijenjen razmatranju povijesti Spasenja u obliku virtualnoga hodočašća
Glagolski oblici u protestantskom izdanju Artikuli ili deli prave stare krstianske vere (1562.)
Authors: Kuštović Tanja
Published: December 2018

Franjo Fancev proveo je jezičnu analizu djela koje su u 16. stoljeću objavili hrvatski protestantski pisci. Premda je u analizu uključio sva hrvatska protestantska izdanja, ona se ipak uglavnom temelji na Novom Testamentu, pri čemu su ostala djela, pa tako i Artikuli, pomalo marginalizirani. Ovaj rad u središte istraživanja postavlja morfološku analizu Artikula. U tekstu se analiziraju jednostavni i složeni glagolski oblici. Nastoji se dokazati prevladavaju
li hrvatski nastavci za izražavanje pojedinih oblika te postoje li razlike u odnosu na ćirilično izdanje Artikula. Uočeno je da se u prezentu pojavljuju nenaglašeni oblici glagola biti, premda još uvijek pretežu naglašeni oblici. Usporedba s Novim Testamentom pokazuje da postoje razlike u upotrebi nekih glagolskih oblika kad je riječ o nastavcima, npr. češća upotreba u Novom Testamentu nastavka -t u 3. licu
jednine prezenta. Takav nastavak u Artikulima ne nalazimo. U ostalim prošlim vremenima kao i u vremenima za izražavanje budućnosti nije uočena razlika između ova dva spomenika. Ako usporedimo Artikule s ostalim hrvatskim tekstovima iz 16. stoljeća, na temelju stanja kakvo je
prikazano u analizama koje su u svojim istraživanjima proveli Boris KUZMIĆ (2015), Iva LUKEŽIĆ (2012, 2015) te Amir KAPETANOVIĆ (2011), možemo reći da su Artikuli, barem kada je o glagolskim oblicima riječ, usklađeni s tekstovima toga vremena
Search for the shortest trajectory of a social engeneering attack between a pair of users in a graph with transition probabilities
Authors: Khlobystova A. O. , Abramov M. V. , Tulupyev A. L. , Zolotin A. A.
Published: December 2018

Introduction: Social engineering attacks can be divided into two types: direct (one-way) and multi-pass ones, passing through a chain of users. Normally, there are several propagation paths for a multi-pass social engineering attack between two users. Estimates of the probabilities of an attack to spread along different trajectories will differ. Purpose: Identification of the most critical (most probable) trajectory for a multi-pass social engineering attack between two users. Methods: Methods of searching, matching and algorithm analysis are used to identify the most critical trajectory of attack propagation. They apply the information about the intensity of the interaction between employees in companies based on data extracted from social networks. These algorithms are reduced, using a number of transformations of the original data, to the algorithms of finding the shortest path in a graph. The estimates of a multi-path social engineering attack success probability are calculated with the methods of constructing an estimate of a complex event probability. Results: We have proposed an approach to identifying the most critical trajectories, whose estimate of the attack success probability is the highest. In the simplest case, the problem can be reduced to finding a path in the graph with the maximum product of the weights of all the edges involved. The resource intensity of the algorithm when searching for the most critical trajectory on a complete graph with a large number of vertices can be reduced with a specially developed technique. A brief overview of the methods and algorithms providing automated search for the most critical propagation path of a social engineering attack showed that in a general case it can be reduced, with some transformations, to the problem of finding the most critical trajectory using the configuration of Dijkstra and Bellman — Ford algorithms. The chosen algorithm was adapted for the specified context, and an approach was proposed to thin out the graph when searching for the most critical trajectory. The presented methods and algorithms are implemented in software code. Numerical experiments were performed to verify the calculation results. Practical relevance: The developed software based on the method and algorithm proposed in this article complements the functionality of the previous versions of software prototypes for analyzing the protection of information system users against social engineering attacks. It allows you to take into account a wider range of factors affecting the assessment of social engineering attack success probability.

Coronary microvascular disease and clinical prognosis in deferred lesions: The index of microcirculatory resistance
Authors: Chung Ju-Hyun , Lee Kyung Eun , Park Jai-Wun , Shin Eun-Seok
Published: December 2018

While fractional flow reserve (FFR) is a good diagnostic index to assess the myocardial ischemia, coronary flow reserve (CFR) and the index of microcirculatory resistance (IMR) can be used to address microvascular status without any significant epicardial disease. The independent predictors for FFR and IMR are totally different and acts differently on the macro- and micro-vascular dysfunction. In high FFR patients, low CFR and high IMR which indicates the presence of overt microvascular disease demonstrated poor prognosis. Thus, comprehensive physiological assessments using FFR, CFR and IMR could improve the ability to discriminate patients at high risk of future events.
Contrast-enhanced ultrasound (CEUS) for the evaluation of gallbladder diseases in comparison to cross-sectional imaging modalities and histopathological results
Authors: Negrão de Figueiredo G. , Mueller-Peltzer K. , Armbruster M. , Rübenthaler J. , Clevert D.A.
Published: December 2018

BACKGROUND:

The first method of choice for gallbladder alteration detection is the conventional ultrasound. Due to some imaging limitations, contrast-enhanced ultrasound (CEUS) has been widely used in the last years. CEUS is an additional modality that is able to depict microvessels flow and elucidate suspicious findings.

OBJECTIVE:

The aim of this retrospective mono-center analysis study is to evaluate the performance of CEUS in gallbladder diseases and compare it to cross-sectional imaging modalities and histopathological results as gold standard.

METHODS:

The retrospective study analysed 37 patients with gallbladder diseases between 2009 and 2017. All patients underwent CEUS examinations and additional cross-sectional imaging was also performed: CT imaging on 24 (64.9%) patients, MRI imaging on 18 (48.6%) patients, CT and MRI imaging on (28.7%). CEUS images were performed and interpreted by a single physician.

RESULTS:

CEUS imaging results of the gallbladder showed a sensitivity and specificity of 100%, a positive predictive value (PPV) of 100% and a negative predictive value (NPV) of 100%. CT imaging of the gallbladder showed a sensitivity of 100%, specificity of 75%, PPV of 100%, and NPV of 95%. MR imaging of the gallbladder showed a sensitivity of 100%, specificity of 93%, PPV of 75%, and NPV of 100%.

CONCLUSION:

Ultrasound imaging plays an essential role in the evaluation of gallbladder disease. Due to additional features of contrast-enhanced ultrasound, it is possible to differentiate gallbladder pathologic alterations by depicting its micro and macrocirculation and display important malignant features that recommends prompt management. Patients with contraindications to other cross-sectional imaging modalities benefit from this safe technique.
Shear-induced platelet adherence and activation in an in-vitro dynamic multiwell-plate system

Published: December 2018

Circulating blood cells are prone to varying flow conditions when contacting cardiovascular devices. For a profound understanding of the complex interplay between the blood components/cells and cardiovascular implant surfaces, testing under varying shear conditions is required. Here, we study the influence of arterial and venous shear conditions on the in vitro evaluation of the thrombogenicity of polymer-based implant materials.

Medical grade poly(dimethyl siloxane) (PDMS), polyethylene terephthalate (PET) and polytetrafluoroethylene (PTFE) films were included as reference materials. The polymers were exposed to whole blood from healthy humans. Blood was agitated orbitally at low (venous shear stress: 2.8 dyne · cm–2) and high (arterial shear stress: 22.2 dyne · cm–2) agitation speeds in a well-plate based test system. Numbers of non-adherent platelets, platelet activation (P-Selectin positive platelets), platelet function (PFA100 closure times) and platelet adhesion (laser scanning microscopy (LSM)) were determined.

Microscopic data and counting of the circulating cells revealed increasing numbers of material-surface adherent platelets with increasing agitation speed. Also, activation of the platelets was substantially increased when tested under the high shear conditions (P-Selectin levels, PFA-100 closure times). At low agitation speed, the platelet densities did not differ between the three materials. Tested at the high agitation speed, lowest platelet densities were observed on PDMS, intermediate levels on PET and highest on PTFE. While activation of the circulating platelets was affected by the implant surfaces in a similar manner, PFA closure times did not reflect this trend.

Differences in the thrombogenicity of the studied polymers were more pronounced when tested at high agitation speed due to the induced shear stresses. Testing under varying shear stresses, thus, led to a different evaluation of the implant thrombogenicity, which emphasizes the need for testing under various flow conditions. Our data further confirmed earlier findings where the same reference implants were tested under static (and not dynamic) conditions and with fresh human platelet rich plasma instead of whole blood. This supports that the application of common reference materials may improve inter-study comparisons, even under varying test conditions.
Acute L-Arginine supplementation does not affect red blood cell aggregation and deformability during high intensity interval exercise in healthy men
Authors: Ahmadizad Sajad , Daraei Ali , Bassami Minoo , Rahmani Hiwa
Published: December 2018

BACKGROUND:

L-Arginine, the precursor of NO might be involved in improving the cardiovascular disorders via regulation of functional properties of erythrocytes.

OBJECTIVE:

This study investigated the effects of L-Arginine supplementation on responses of red blood cell (RBC) properties to high intensity interval exercise (HIIE).

METHODS:

Ten overweight healthy men participated voluntarily in the study and performed two HIIE trials with and without L-Arginine in two separate weeks. The HIIE protocol included 12 intervals of 3-min encompassed 1-min running at 100% of vVO2max and 2-min active recovery at 40% of vVO2max. Three blood samples were taken before and after supplementation, and immediately after exercise; and were used to measure red blood cell properties.

RESULTS:

The HIIE protocol increased hematocrit, hemoglobin and lactate significantly ( P < 0.05), but had no significant effect on RBC aggregation, RBC deformability, and fibrinogen concentration. When data were compared for two trials no significant differences between the responses of RBC properties to two HIIE protocols were detected ( P > 0.05), whereas the increases in lactate concentration following HIIE was significantly lower in L-Arginine than placebo trial ( P < 0.05).

CONCLUSIONS:

It is concluded that L-Arginine consumption prior to HIIE does not lead to any improvement in RBC properties during HIIE in overweight healthy men.

Finite element method and experimental investigation for hairline crack detection and characterization
Authors: Okolo Chukwunonso K. , Meydan Turgut
Published: December 2018

This paper reports on a quantitative technique based on the Magnetic Flux Leakage (MFL) method, for the detection and interpretation of the MFL signals caused by rectangular hairline cracks in pipeline structures. This was achieved through visualization and 3D imaging of the leakage field. This research is aimed at detecting hairline cracks caused by granular bond separation, which occurs during manufacturing, leaving pipelines and steel structures with miniature cracks. The investigation compared finite element numerical simulation with experimental data. The response of the MFL probe scanned above a hairline crack was first predicted using an optimized 3D finite element model. The MFL signals associated with both the surface and far-surface cracks were compared. The results show that the depth, width and length of the various hairline cracks can be estimated by using the distribution pattern and strength of the ( B x), ( B y) and ( B z) components of the MFL signals.

Mobilizing Parkinson’s Disease: The Future of Exercise
Authors: Ellis Terry , Rochester Lynn
Published: December 2018

Exercise is increasingly recognized as an important element in the treatment of Parkinson’s disease but what is exercise targeting? What accounts for the benefits observed in Parkinson’s disease? Is exercise disease modifying? Several modes of exercise have been studied in various doses across a heterogeneous Parkinson’s population. Yet more clarity is needed as to who benefits most and when, from what type of exercise and at which intensity. In this paper, we briefly review the state of the art in key areas and speculate on the likely state of research in each area in the next 20 years. Key areas relate to: (1) the physiological benefits of exercise with respect to disease modification; (2) the best type of exercise; (3) the optimal intensity of exercise; and (4) implementation strategies to increase exercise uptake. A better understanding of these concepts would allow for a more effective, personalized approach, rather than the current “one size fits all” and could most likely confer greater benefits.

Published: December 2018

High cost of the ferromanganese production by traditional methods resulted in searching of new technologies for its production. The main objective of the study was to establish the technological parameters of a new process for the ferromanganese production by using ITmk3 process elements in laboratory conditions. The studies were carried out in the “Nabertherm” chamber furnace, which allows for simulate the temperature and time parameters of ITmk3 process elements in a rotary hearth furnace.

The charge for ferromanganese obtaining consisted of manganese ore from the Zhayremsk deposit (Kazakhstan) and non-scarce coal, the consumption of which provided close to stoichiometric one in carbon for the direct reduction of manganese and iron from the correspondent oxides. The composition of the ore gangue and coalash provided a mixture with a slag melting point below 1400 °C.

The maximum yield of ferroalloy and the conversion of manganese into the ferroalloy from the burden was achieved at a temperature and duration of thermal treatment of 1500 °C and 10 min, respectively. Information obtained during the study may be used for large-scale testing in a commercially size rotary hearth furnace.
Main conditions of rational technological solutions of injection processes for ladle desulphurization of hot metal by various dispersed reagents
Authors: Shevchenko A. F. , Manachin I. A.
Published: December 2018

Application of dispersed reagents in hot metal ladle treatment processes enabled for solving a wide range of tasks of increasing metal products quality and improving technical and economic indices of metal smelting processes. But there are reserves of existing technologies improving, since during their application a whole number of peculiarities of heat- and mass exchange processes, having place in ladle at wide range of parameters and refining conditions, are not taken into consideration. Therefore, elaboration of conceptions about exchange processes mechanisms at different reagents injection input and elaboration of most rational technological solutions are rather actual.

Influence of chemical and fraction-dispersed content of reagents on hot metal desulphurization processes studied. First priority of CaO and Mg application justified.

It was shown, that when using fine powders, particles less 0.08 mm practically do not penetrate into hot metal melt, and when grain reagents (0.2–1.6 mm) are used, their particles can penetrate into hot metal by a depth of 25 mm.

It was established that during the injection desulphurization there are conditions and separation of blow-in two-phase stream takes place in near-tuyere zone with division for gas and solid components.

During the desulphurization by powder non-magnesium reagents (lime), the powder concentration 40–60 kg/Nm3 in gas justified, usage of reducing agents not from hot metal components (С, Si, Mn), but Al introduced from outside. Besides, it was recommended to introduce evaporating and gas-forming (in the melt) additions into gas and solid phase for additional phase dispersion in the neartuyere zone.

During the magnesium mono-injection its application in the form of grains (0.2–1.6 mm) justified and blow-in velocity >80 m/s.

The obtained scientific preconditions of hot metal desulphurization efficiency increase by different reagents were checked in industrial conditions.

Authors: Yur’ev B. P. , Dudko V. A.
Published: December 2018

Main reactions of iron ore pellets desulphurization are considered in details in a number of papers, in which the results obtained refer only to their isothermal heating. Therefore studies of authors were concentrated on desulphurization kinetics of nonfluxed and fluxed Sokolov-Sarbai and Kostomuksha pellets, having different content of initial Sulphur in concentrate at nonisothermal heating.

Regime peculiarities of sulphuric pellets thermal treatment in a layer considered. Recommendations on roasting regime of pellets layer elaborated, which enable to decrease the sulfates decomposition degree.   

The mechanism and kinetics of calcium sulfate dissociation at temperatures and gas content, typical for conveyer and sintering machines, studied. The temperature level determined, at which maximum dissociation velocity of calcium sulfate is reached. 

Simulation of the process of pellets thermal treatment in air and in helium media realized. It was shown that at roasting in a lowoxidizing atmosphere the sulphur content in pellets, roasted at correspondent temperatures, was decreased considerably. Rational iron ore pellets roasting regimes elaborated aimed at their acceptable properties both by strength and by Sulphur content.

Published: December 2018

Items of durability increase of blower nozzle and reduction of heat losses through their surface are actual today. Reduction of heat losses is reached by different ways, including application of heat isolation insertion. 

In the Ansys Fluent media within a frame of stationary and non-stationary approaches, a simulation of process of fluid media movement, heat exchange and temperature field of the heat isolation insertion, installed into the internal cylinder of the blast furnace blower nozzle both with an air gap and without air gap carried out. The calculated area considered, which included fluid media inside the blow channel of the nozzle and heat isolation insertion. Availability of the internal cylinder, air gap, separating the cylinder from the insertion, and heat exchange with the nozzle cooling water were taken into consideration within expanded boundary conditions. It was shown, that the insertion, installed into the internal cylinder with air gap, has higher temperature in stationary position and better decreases heat losses through the internal cylinder, than the insertion, installed into the internal cylinder without air gap. Maximum temperature drop between the insertion surfaces, installed into the internal cylinder without air gap, is reached in stationary state. For the insertion installed in the internal cylinder with air gap, during heating a shot–term drop increase was observed, following by a decrease till the value, corresponding to stationary state (which is considerably smaller than that at no gap conditions).

A mechanism of electroplastic effect considered as well as possible areas of its technological application during rolling, drawing, stamping of thin sheets and other methods of metals forming.

A conception justified that metal electroplastic deformation, based on electroplastic effect, can be applied at middle and final metallurgical stage. Electroplastic effect allows to decrease metal resistance to deformation by 25–30% and increase the ductility of a metal during its forming, to increase residual ductility till 30%. Due to increasing of axial texture perfection degree of wire during drawing technology with electroplastic effect application, a decrease of its electric resistance by 15% is reached. During the metal electroplastic deformation of stainless steels the austenite-martensitic phase γ→α transformation is practically completely suppressed, which makes unnecessary operations of money-and energy consuming austenizating annealing.

Based on electroplastic effect about 45 mills and powerful metal-processing facilities, using metal electroplastic effect deformation created in different countries (mainly in Russia, South Korea, Italy, Great Britain and China). Different variants of effective energy-saving critical technologies are being developed by metal electroplastic effect deformation by rolling, drawing, stamping and flatting, as well as briquetting of metal wastes with current. A new equipment is created and existing equipment is modernized for application of metal еlectroplastic effect deformation technology.

A pipeline is refered to metal structures of increased danger. To provide a high operational safety of pipe lines it is common to follow requirements to steels by level of strength, ductility, impact strength, cold resistance, fracture strength, weldability, corrosion resistance and other properties, forming of which is influenced by a complex of different factors (both technological and operational).

At present structural low carbon low alloyed steels with increased level of properties, completely meeting all complex of presented requirements are used for production of sheet rolled products for pipes. However, during longtime operation of a pipeline, properties degradation demonstration is possible, that can result in decreasing of safety and originating of a structure destroying probability. A passing of strain ageing can be one of the reasons, responsible for state alteration of longtime operation pipes metal, resulted in increasing of yield strength to ultimate strength (σ0,2/σв) relation, decreasing of impact strength and cold resistance.

Results of study of strain ageing influence on complex of properties and structural state of sheet rolled product of X80 strength class presented, the product being widely used for pipes production. It was shown, that in the process of the strain ageing, apart from decreasing of complex of standard properties, an increase of relaxation effect takes place. It speaks for an increased level of local strains, arising at loading and deformation as a result of fixing of dislocations by interstitial atoms. Concentration of the atoms is increasing in the process of preliminary deformation, which is confirmed by Snuk peak arising during measuring of internal friction.

Study of structural state by different methods enabled to formulate peculiarities of strain deformation mechanism, typical for a steel with a structure of low carbon bainite type (bainite ferrite) with austenite insertions. Alteration of properties during strain ageing of bainite steel is linked with simultaneous arising of two processes in structure at different scale levels, having contrary influence on resistance to deformation. Increase of yield strength as a result of strengthening takes place because of fixing of dislocations by interstitial atoms. At the same time the weakening is caused by disappearing of M/A phase islands, which is strengthening the metal at the initials state, as a result of TRIP-effect during preliminary deformation and martensite disintegration during the following heating.

Nilai perusahaan merupakan kondisi tertentu yang telah dicapai oleh suatu perusahaan sebagai gambaran kepercayaan masyarakat terhadap perusahaan tersebut. Nilai perusahaan ditentukan setelah perusahaan melalui proses kegiatan selama beberapa periode, yaitu sejak perusahaan tersebut didirikan hingga saat ini. Strategi bisnis yg tepat perlu diterapkan guna memenangkan persaingan yang terjadi antar perusahaan. Prospector dan defender diartikan sebagai strategi yang ekstrim berbeda. Prospector merupakan strategi yang mengidentifikasi dan mengembangkan produk baru serta memanfaatkan peluang pasar, sedangkan defender adalah strategi yang cenderung mempertahankan pasar yang telah dicapai dan produk yang stabil dengan harga yang murah. Sistem kompensasi merupakan salah satu cara yang akan menentukan bagaimana individu berperilaku dalam organisasi dan peran individu dalam organisasi akan mempengaruhi perkembangan organisasi. Selain itu ukuran perusahaan dinilai mampu mempengaruhi nilai perusahaan tersebut. Dikarenakan semakin besar perusahaan maka semakin mudah perusahaan tersebut dalam hal pendanaan baik oleh investor maupun kreditur. Tujuan dari penelitian ini adalah membuktikan secara empiris apakah strategi prospector dan defender, kompensasi eksekutif, ukuran perusahaan berpengaruh positif terhadap nilai perusahaan. Sejauh ini jumlah perusahaan yang masuk dalam sampel penelitian adalah sebanyak 123 perusahaan.

From the time in memorial, Information Security has remained a primary concern and today when most of the sensitive data is stored on Cloud with client organization having lesser control over the stored data, the fundamental way to fix this issue is to encrypt such data. So, a secure user imposed data access control system must be given, before the users outsource any data to the cloud for storage. Attribute Based Encryption (ABE) system is one such asymmetric key based cryptosystem that has received much attention that provides fine-grained access control to data stored on the cloud. In this paper, we propose a more proficient and richer type of Attribute Based Encryption technique (RSABE) that not only considers the Outsourced ABE construction but also address the issue of revocation in case of change of attributes of the group user or organization; once a user is removed from the group, the keys are updated and these new keys are distributed among the existing users also our system supports the Keyword search over encrypted data in the mobile cloud storage. In multi keyword search; data owners and users can generate the keywords index and search trapdoor, respectively, without relying on always online trusted authority. Experimental results prove that the performance of the proposed system is greater than existing system in terms of security, time consumption and memory utilization & data availability.

La protección ambiental objeto de estudio de múltiples disciplinas, desde las ciencias naturales, las ciencias ambientales, las ciencias técnicas, como de las ciências sociales. Dentro de estas últimas, el Derecho como ciencia, posibilita la búsqueda del acatamiento por sus destinatarios de todo lo relacionado con la protección, conservación, mitigación e rehabilitación del ambiente, así como la elevación de la conciencia y de la cultura jurídica. Hoy está en juego la propia existencia del hombre, se requiere un cambio em la conducta de este con relación al entorno que permita realizar, de manera sostenible, la satisfacción de las necesidades siempre crecientes de la sociedad en correspondencia con las condiciones socio-económicas, culturales, estéticas, educacionales, legales, etc. Angola, como nación, no está exenta de los problemas ambientales que se manifiestan en el planeta, es por ello que desde la época colonial hasta nuestros días se han dictado normas ambientales para la protección del ambiente, sin una adecuada eficacia y eficiencia que permitan proteger a la naturaleza de forma adecuada, originándose incidentes ambientales. De aquí la necesidad de aplicar el Derecho Penal ambiental.
