Authors: García Villar Héctor Adrián , Hernández Gómez Juan Carlos , Campos Hernández Yanet , Pérez Vázquez Ulises 
Published: January 2018

En este documento se analizará la manera de incursionar al mercado extranjero; como es que las actitudes definen la conclusión de una negociación y se demostrará la importancia de la concepción de otras culturas distintas a la nuestra principalmente en el continente asiático; se proponen soluciones y consejos de negociación, específicamente con tres fuertes economías asiáticas con potencial de inversión bastante alta: Japón, Taiwán y China y como es que un negociador mexicano puede abordar dicho nicho de mercado. De igual forma, se exponen ventajas y desventajas del negociador mexicano, para, finalmente, hablar sobre las claves de negociación con un mexicano, y como es que éste reacciona en distintas regiones.
Reinventando el modelo de negocios
Authors: Cerón Islas Heidy , Ramírez Ortega Joel 
Published: January 2018

Los Modelos de negocios que generan valor, cambian el juego de conveniencia para el consumidor. Las innovaciones en los modelos de negocios han reconfigurado industrias enteras y miles de millones de dólares de valor redistribuido.
Para el crecimiento a través del modelo de negocio se tienen dos problemas. La primera es la falta de definición del negocio, dado que poco estudio formal se ha hecho en la dinámica y los procesos de desarrollo del modelo de negocio. En segundo lugar, pocas compañías entienden su modelo existente detrás de su desarrollo, sus interdependencias naturales, sus fortalezas y limitaciones.
Son tres pasos para trazar la ruta hacia la construcción del modelo y ver más allá de las fronteras, se inicia por pensar en la oportunidad de satisfacer un cliente real, el segundo paso es la construcción de un proyecto en el que se incluya el qué y cómo la empresa va a satisfacer esa necesidad y generar un beneficio. La tercera es la comparación entre su modelo y uno ya existente para ver cuánto tendría que cambiar para capturar la oportunidad de negocio. En el modelo propuesto, el plan debe contener cuatro elementos.
No es posible inventar o reinventar un modelo de negocio sin definir previamente una propuesta clara de valor al cliente. Las barreras más comunes de las personas para conseguir una determinada propuesta son: la riqueza, el acceso insuficiente a la información, habilidad y el tiempo. A menudo pueden crear nuevos productos que imitan de los competidores sin modificar sustancialmente su propio modelo de negocio, lo relevante sería encontrar el ADN de la innovación que se propone.

The concept of knowledge and knowledge management in the Romanian business field
Authors: Feraru Andreea 
Published: January 2018

The concepts of knowledge and knowledge management have a significant position at the business level in Romania. Their importance is given by a created competitive advantage among organizations. Such knowledge is lived and felt experience, the use that may lead to several results. Knowledge Management was developed as a philosophy and applications by companies, but it offers a number of concepts and models which can be expanded regionally to generate significant positive impact on regional development. That education and knowledge are considered assets of a business productive, as they may be primary factors in making a most valuable product or service. The scope of knowledge management in Romania is the process that occurs in the organization and coordination of knowledge of each organization separately.

Published: January 2018

Abstract
From ancient times to the present, copper alloys, brasses and bronzes are used for marine applications due to their high resistance to sea water. In time, numerous of copper alloys have been developed and manganese (Mn) and aluminium (Al) bronzes are the well-known members of this large family. They have superior properties and are used to produce some critical components of boats. These alloys are in competition with each other. For this reason, C86500 Mn bronze and C95800 Al bronze were evaluated in this study. Mechanical and corrosion tests were carried out on specimens which were taken from sand castings. Tensile, impact and hardness tests were applied to determine mechanical properties. Corrosion behaviour of the alloys was characterized in HCl, NaCl, and H2SO4 solutions. Additionally, microstructure observations and a definition of phases were realized. According to mechanical tests results, Al bronze has better properties than Mn bronze. Moreover, Mn bronze provides lower corrosion rates in HCl solution as Al bronze in H2SO4. Intergranular corrosion was detected in HCl solutions. Moreover, some micro shrinkage zones were seen on an Al bronze specimen after corrosion tests.
Mass Heritage of New Belgrade: Housing Laboratory and So Much More
Authors: Jovanović Jelica 
Published: January 2018

The central zone of New Belgrade has been under tentative protection by the law of the Republic of Serbia; it is slowly gaining the long-awaited canonical status of cultural property. However, this good news has often been overshadowed by the desperation among the professionals, the fear among flat owners and the fury among politicians: the first because they grasp the scale of the job-to-be-done, the last because it interferes with their hopes and wishes, and the second because they are stuck between the first and the third group. This whirlpool of interests shows many properties of New Belgrade, that stretch far beyond the oversimplified narratives of ‘the unbuilt capital of Yugoslavia’, ‘the largest dormitory of Belgrade’ and ‘the unrestrained modernist playground’. This paper attempts to offer other points and value nods to those that are the most frequently used, from the complexity of the integrative efforts to the emergence of this new city, as well as the omitted and overlooked aspects of its reconstruction, deregulation and failure. The focus of the paper is the emergence, the use and the disappearance of the peculiar Yugoslav prefabricated housing, the path less travelled.
Att problematisera ”problemet”: Bedömning och utveckling av problemformuleringar i lärarutbildningens självständiga arbeten
Authors: Karlsudd Peter 
Published: January 2018

How well a research problem is formulated in theses, according to many educators and textbook writers, is of great importance for the final quality of a thesis project. To investigate if there is a link between the construction and formulations of a problem and the grades well accepted and accepted, 58 theses projects were reviewed. 82 students were tested on their ability to evaluate, discuss and formulate research problems through specific exercises. The results of the comparison between how the research problem was designed and the theses gradings show that a well-formulated problem is not an absolute necessity for the grade well accepted. However, the results indicate that writers who strive to express higher ambitions when it comes to the problem have a greater opportunity to realize these in their thesis. Highly formulated problems have been well represented among the theses that receive the grade well accepted.
The conclusion of the study shows that a well constructed purpose and problem is of particular importance to achieve a good standard of a thesis project and the specific training efforts undertaken suggest that this training will continue as a regular feature of the programme.
On the Mass and Luminosity Functions of Tidal Disruption Flares: Rate Suppression due to Black Hole Event Horizons
Authors: Velzen S. van 
Published: January 2018

Abstract
The tidal disruption of a star by a massive black hole is expected to yield a luminous flare of thermal emission. About two dozen of these stellar tidal disruption flares (TDFs) may have been detected in optical transient surveys. However, explaining the observed properties of these events within the tidal disruption paradigm is not yet possible. This theoretical ambiguity has led some authors to suggest that optical TDFs are due to a different process, such as a nuclear supernova or accretion disk instabilities. Here we present a test of a fundamental prediction of the tidal disruption event scenario: a suppression of the flare rate due to the direct capture of stars by the black hole. Using a recently compiled sample of candidate TDFs with black hole mass measurements, plus a careful treatment of selection effects in this flux-limited sample, we confirm that the dearth of observed TDFs from high-mass black holes is statistically significant. All the TDF impostor models we consider fail to explain the observed mass function; the only scenario that fits the data is a suppression of the rate due to direct captures. We find that this suppression can explain the low volumetric rate of the luminous TDF candidate ASASSN-15lh, thus supporting the hypothesis that this flare belongs to the TDF family. Our work is the first to present the optical TDF luminosity function. A steep power law is required to explain the observed rest-frame g-band luminosity,

. The mean event rate of the flares in our sample is

galaxy−1 yr−1, consistent with the theoretically expected tidal disruption rate.
Evershed and Counter-Evershed Flows in Sunspot MHD Simulations
Authors: Siu-Tapia A. L. , Rempel M. , Lagg A. , Solanki S. K. 
Published: January 2018

Abstract
There have been a few reports in the literature of counter-Evershed flows observed in well-developed sunspot penumbrae, i.e., flows directed toward the umbra along penumbral filaments. Here, we investigate the driving forces of such counter-Evershed flows in a radiative magnetohydrodynamic simulation of a sunspot, and compare them to the forces acting on the normal Evershed flow. The simulation covers a timespan of 100 solar hours and generates an Evershed outflow exceeding 8 km s−1 in the penumbra along radially aligned filaments where the magnetic field is almost horizontal. Additionally, the simulation produces a fast counter-Evershed flow (i.e., an inflow near

) in some regions within the penumbra, reaching peak flow speeds of ∼12 km s−1. The counter-Evershed flows are transient and typically last a few hours before they turn into outflows again. By using the kinetic energy equation and evaluating its various terms in the simulation box, we found that the Evershed flow occurs due to overturning convection in a strongly inclined magnetic field, while the counter-Evershed flows can be well-described as siphon flows.
Evidence that the Planetary Candidate CVSO30c is a Background Star from Optical, Seeing-limited Data
Authors: Lee Chien-Hsiu , Chiang Po-Shih 
Published: January 2018

Abstract
We report serendipitous optical imaging of CVSO30c, an exoplanet candidate associated with the pre-main-sequence T Tauri star CVSO30 that resides in the 25 Ori stellar cluster. We perform PSF modeling on our seeing-limited optical image to remove the lights from the host star (CVSO30), allowing us to extract photometry of CVSO30c to be g = 23.2 ± 0.2 (statistic) ± 0.1 (systematic) and r = 21.5 ± 0.1 (statistic) ± 0.1 (systematic) magnitudes, respectively. This is 170 and 80 times too bright in the g and r bands, respectively, if CVSO30c were an L0 substellar object as suggested by previous studies. The optical/infrared colors of CVSO30c are indicative of a stellar, not substellar object, while the object’s color–magnitude diagram position is strikingly inconsistent with expected values for a low-mass member of 25 Ori. Broadband photometry for CVSO30c is instead better fit by contaminants such as a background K3 giant or M subdwarf. Our study demonstrates that optical seeing-limited data can help clarify the nature of candidate wide separation planet-mass companions in young star-forming regions.
Osnovne fizikalno kemične značilnosti kraških voda na Notranjskem
Authors: Kogovšek Janja 
Published: January 2018

V letih 1986 in 1987 je bilo zajetih 7 serij vodnih vzorcev na 36 do 47 mestih na Babnem, Loškem in Cerkniškem polju, na Blokah in Loškem potoku za fizikalno-kemične analize, ki so pokazale na kakovostno stanje teh voda.Z apnenčastega in dolomitnega sveta, ki obdaja Babno, Loško in Cerkniško polje se steka padavinska voda v izvire, ki napajajo ponikalnice. Večina izvirnih voda označuje vsebnost nitratov pod 4 mgNO3 -/l, kloridov pod 5 mg Cl-/l in vsebnost fosfatov okoli 0.05 mg PO43-/l. Bakteriološke analize so pokazale oporečno vodo, le nekaj izvirov pa je bilo občasno neoporečnih. Znatno slabšo kakovost imajo Pudobski, Podgorski in Mežnarjev studenec s poseljenim zaledjem ter ponikalnice na ponorih, kjer smo določali do 20 mg/l nitratov in kloridov, fosfatov pa do 5 mg/l. Ponikalnice na svoji poti po kraških poljih sprejemajo onesnaženje zaradi poseljenosti in industrije. Ker pa se voda ponikalnic pojavlja zaporedno na več niže ležečih poljih, pomeni to prenos in kopičenje onesnaženja po toku navzdol, tudi v izvire, ki so zajeti za oskrbo prebivalstva s pitno vodo. In 1986 and 1987 seven series of samples were taken at 36 to 47 sampling points on Babno, Loško and Cerkniško Polje and on Bloke and at Loški potok in order to find out their physico-chemical properties and their quality. Rainwater flows from the limestone and dolomite landscape around Babno, Loško and Cerkniško polje into springs feeding the sinking streams. The nitrate level at most of the springs was below 4 mg NO3-/l and chloride below 5 mg Cl-/l; the o-phosphate level varied around the value of 0.05 mg PO4 3-/l. The bacteriological analyses of the spring waters showed that they are not of drinking quality and only few springs were seasonally of good quality. Poorer quality was found in springs with populated catchments, such as are Pudobski Izvir, Podgorski and Mežnarjev Studenec and, obviously in all the sinking waters at swallow-holes where the nitrate and chloride level was up to 20 mg/l and phosphate up to 5 mg/l. Flowing over karst poljes this water receives pollution due to habitations and industry. As the water of these sinking streams reappears downstream in several lower-lying karst poljes this results in the transport and accumulation of pollution downstream even in springs that are captured for water supply.
Značilnosti pretakanja voda v kraškem zaledju Temenice

Published: January 2018

Povzete so ugotovitve predhodne študije o vplivu načrtovanega avtocestnega odseka Trebnje - Hrastje na kraško vodo, ki je bila izdelana na osnovi terenskega ogleda in pregleda dosedanjih raziskav. Sledilni poskus je pokazal pretakanje vode iz Lukovškega potoka do izvira Zijala s hitrostjo 0.45 cm/s in nato do izvira Prečne, ki se pomembno obogati z vodo iz kraškega vodonosnika Suhe krajine, s hitrostjo 4.1 cm/s. Ob visokih in najvišjih vodostajih lahko pričakujemo opazno hitrejše pretakanje in z vodo tudi hiter prenos morebitnega onesnaženja. Hitrost in način odtoka padavin s površja neposredno v kraško notranjost še ni bil raziskan. Povezavo Bršljinskega z Lukovškim potokom pa glede na rezultate sledenja ocenjujemo kot vprašljivo. Results of the preliminary study of influences of the planned highway sector Trebnje - Hrastje on karst waters are summarized. The study was based on field survey and review of previous researches. Underground water flow from the stream Lukovški potok to the Zijalo spring with average velocity 0.45 cm/s and further on to the Prečna spring with velocity 4.1 cm/s was proved. This second part of flow is significantly enlarged by recharge from the karst aquifer of Suha krajina. At high and highest waters rather faster flow can be expected and at the same time also fast spreading of eventual pollution. Velocity and mode of infiltration of rain directly into the karst underground was not defined yet. Based on the results of tracing test the underground connection between the Bršljinski potok and Lukovški potok can be estimated as questionable.

Published: January 2018

A detailed study of the microclimate of Petites Dales karst cave with single-entrance is presented in this paper. Two years of cave monitoring investigate temperature, weight of water vapour and airflow distributions outside and inside the cavity to determine the global behaviour of the karst cave. In addition, daily measurements of temperature and airflow demonstrate clearly the stratification of the air and inversions of the airflow during day-time. The cave air is intensively exchanged with external air during the years, with two main modes: (i) airflow enters from the ceiling during summer period and (ii) airflow enters from the floor during winter. At the entrance, an Sshaped velocity profile was observed and far from the entrance, convection loops were observed. During the other period of the year, the airflows may switch from top to bottom or conversely. The thermodynamic conditions of switching are discussed in this paper. This study provided for the first time evidence of daily airflow inversion. Study of cave climates is required in the comprehension of cave flora and fauna, thermodynamic conditions for karst processes underground, hydrogeological features of speleothems, human impact when caves are visited.Key words: cave, microclimate, karst, airflow, temperature, variability. Dnevni in sezonski obrati smeri zračnega toka v jami Petites Dales, Normandija, Francija V članku poročamo o podrobni mikroklimatski študiji v jami Petites Dales. V jami z enim samim vhodom smo dve leti opazovali temperaturo, vlago in porazdelitev zračnih tokov. Podrobne dnevne meritve temperature in zračnega toka kažejo na stratifikacijo in dnevni obrat smeri toka. Poleti zunanji zrak vdira v jamo pri stropu, pozimi pa pri tleh. Pri tem se pri vhodu oblikuje profil hitrosti zraka v obliki črke S, globlje v jami pa konvekcijska zanka. V vmesnih obdobjih lahko pride do preklapljanja iz dotoka pod stropom v dotok pri dnu in obratno, kar v članku obravnavamo z vidika termodinamike. V tej raziskavi smo prvič pojasnili dnevne obrate smeri zraka v primerljivih jamah. Študije jamske mikroklime so pomembne za razumevanje jamskega ekosistema, procesov v jamah ter človekovega vpliva nanje.Ključne besede: jama, mikroklima, kras, zračni tok, temperatura, spremenljivost.
The Effects of Dendritic Cell Hypersensitivity on Persistent Viral Infection
Authors: Tsau Jennifer S. , Huang Xin , Lai Chen-Yen , Hedrick Stephen M. 
Published: January 2018

Abstract
Caspase-8 (CASP8) is known as an executioner of apoptosis, but more recent studies have shown that it participates in the regulation of necroptosis and innate immunity. In this study, we show that CASP8 negatively regulates retinoic acid–inducible gene I (RIG-I) signaling such that, in its absence, stimulation of the RIG-I pathway in dendritic cells (DCs) produced modestly enhanced activation of IFN regulatory factor 3 with correspondingly greater amounts of proinflammatory cytokines. In addition, mice lacking DC-specific CASP8 (dcCasp8−/− mice) develop age-dependent symptoms of autoimmune disease characterized by hyperactive DCs and T cells, spleen and liver immunopathology, and the appearance of Th1-polarized CD4+ T cells. Such mice infected with chronic lymphocytic choriomeningitis virus, an RNA virus detected by RIG-I, mounted an enhanced lymphocytic choriomeningitis virus–specific immune response as measured by increased proportions of Ag-specific CD4+ T cells and multicytokine-producing CD4+ and CD8+ T cells. These results show that CASP8 subtly modulates DC maturation, which controls the spontaneous appearance of autoimmune T cells while simultaneously attenuating the acquired immune system and its potential to control a persistent viral infection.
