Crecimiento económico y flujos de efectivo en las empresas del sector servicios de Cundinamarca

Through this thesis research, which aims to measure the existing relational effect between economic growth and cash flows of the service sector in the department of Cundinamarca it is exposed. And from there propose a model that allows the prediction of future cash flows by reference to economic growth. For this work focuses on 328 companies in the sector and department in question, which have been reporting their accounting and financial statements, all loa years, from 1995 to the superintendency of companies. Becoming the basic source these underlying empirical and statistically the results of this investigation Prior to the development of simple regression model and relational obtaining the effect of the two variables of study; a theoretical compiled from the various investigations that have been made concerning the two variables under study was presented. In the first instance by the concepts and principles that have made financial science on cash flow, and contributions in relation to the construction of models and relationships with the different variables of the economy. Also I was investigated about economic growth, taking as main reference the Solow model and its theoretical development on growth. This in order to present the factors that relate to these two variables and on which the liquids will play a predominant role, which is also analyzed with special emphasis in this investigation. Under these theoretical premises, the fact is evident, that have not yet been advanced research function to relate the two key variables of work. And even less that have been used as the basis for a new model. So there is a theoretical vacuum which explains the rationale for this work. Finally, the work provides a characterization of the economic sector on which rests the investigation. Through a historical overview of the services sector in the department of Cundinamarca, and a qualitative analysis that compares the results of cash flow in recent years and its relationship with economic development in the same sector, for the given period; from the prevailing economic aspects of Cundinamarca recent history, with their respective conclusions and recommendations.
Light-Controlled synthetic enzyme cascades

There is an urgent need for the development of greener syntheses procedures if mankind wants to maintain an environment worth living in but is at the same time unwilling to accept a reduction in material comfort. The establishment of more biocatalytic steps in chemical syntheses is one possible solution, as enzymes and whole cells offer sustainable advantages, such as biodegradability, intoxicity, high selectivity, and many more. As a myriad of enzymatic reactions exist for almost any product, their potential is immense. Great scientific achievements and new techniques recently developed have enabled the design of economically and ecologically feasible multi-step enzyme cascades. However, with these new opportunities, also new challenges arise. The more enzyme steps are combined in one pot, the higher the risk of undesired cross-reactivity is. There is thus an urgent need for a tight control of each biocatalytic step in a cascade in order to obtain the desired product in a high purity and to make use of all advantages that enzyme cascades intrinsically offer. With LightCas, I aim to break new grounds in the area of multi-step (bio)catalysis by enabling an orthogonal, selective and thus flexible on/off tuning of enzymes in a cascade. By entrapping enzymes into light-switchable microgels, using photo-switchable active site lids and light-induced enzyme deactivation, three methods providing the opportunity to control enzyme activity in vitro and in vivo on demand will be (further) developed. The ultimate goal is to set up a one-pot multi-step light-controlled enzyme reactor yielding the desired product in high selectivity and concentration in a technically self-regulated manner.
Beyond the ground-breaking direct impact in the field of enzyme catalysis, huge gains in knowledge are expected from LightCas with respect to the application of intelligent stimuli-responsive materials as well as new, advanced methods for applications in the clinical and research environment.

Rapid discovery and development of enzymes for novel and greener consumer products

The application of enzymes in industrial processes is increasingly important to achieve the EU’s sustainability goals and strengthen the bioeconomy, replacing oil-based chemistry. However, enzymes still find hurdles for their industrial application: low success rates of discovery and engineering; tedious and expensive methods to explore diversity; and limited activity/stability in the final application.   RADICALZ assembles an interdisciplinary and intersectoral consortium to deliver faster, more versatile and more affordable tools for enzyme discovery and engineering, enabling the development of novel enzymes, new formulations and ingredients for more environment-friendly and healthier consumer products. This project will: i) develop new droplet microfluidic tools to find suitable enzymes for consumer products; ii) develop user-friendly software solutions based on machine learning (ML) for faster and more accurate enzyme engineering; iii) develop novel enzymes and bio-based, bio-catalytically synthesized ingredients for consumer products (glycosides, wash-enhancing enzymes, bio-based thickeners, natural antioxidants and fragrances); iv) develop bio-based, condition-responsive capsules for the protection and triggered release of enzymes and ingredients in the formulation of consumer products.  RADICALZ will reduce the average time for enzyme discovery and evolution to <4 weeks, access 10 bio-based ingredients to replace oil-based chemistry, reducing the environmental impact –supported in depth in ≥3 cases– across 3 different types of consumer products. RADICALZ assembles 6 leading European companies and 6 pioneer academic teams expert in enzyme discovery and evolution, biocatalysis, chemical engineering, microbiology, soft-matter physics and microfluidics. The planned activities span 48 months and 7 work packages. The project is estimated at ca. 6 M€ (42% allocated to industrial partners and 64% of the total dedicated to creating highly-qualified jobs).
Simulación e implementación de algoritmos de generación de trayectorias en el sistema de robótica modular MECABOT

The modular robotic system MECABOT, developed by the DAVINCI research group from Universidad Militar Nueva Granada is currently on its fifth version. With it, several architectures can be achieved, like the serpent, caterpillar, wheel, hexapod and recently the development of a quadruped architecture was accomplished. This work will be based on the last one mentioned. The locomotion of each architecture is determined by sequences of previously defined actions. The current document is focused on the search, selection, programming, and implementation of an algorithm for trajectory generation that allows the displacement of the MECABOT 5.0 robot through terrains with various obstacle configurations.
Life Cycle based Energy Audit

Energy is an essential ingredient in nearly all goods and services, but its use exacts heavy financial, environmental, and security costs. A key method of reducing energy costs while retaining its benefits is to use it more efficiently. Industry is a very large consumer of energy and has unexploited potential for energy savings. To lower the intensity of industrial energy dependency one has to address SMEs. Here, transnational cooperation is vital for connecting partners looking for joint solutions and open new opportunities for companies and improving existing policies.   

 

The goal of the LiCEA project, which connects six partners from five central European countries, is to develop and apply smart tools that allow the discovery of numerous unexploited energy saving opportunities in regional industrial clusters along the supply chain of SMEs.
The Ethnic Security Dilemma and Ethnic Violence: An Alternative Empirical Model and its Explanatory Power

Beginning in the 1990s, a trend of using the security dilemma to explain ethnic violence has emerged. However, previous research mainly focuses on individual cases with large-scale violence; whether ethnic security dilemma theory is a sound approach to explain less violent ethnic conflict remains unclear. This paper employs a large-N design and tests the hypothesis that the ethnic security dilemma causes ethnic conflicts, without discriminating between differences in severity and scale of conflict. The paper also conducts a longitudinal comparison with a previous quantitative model using the latest data available. The empirical results do not support the hypothesis and suggest that the explanatory power of the ethnic security dilemma has declined over time. Although there is no definite conclusion that the ethnic security dilemma is not a useful explanation for less violent ethnic conflicts, given the limitations of this research, I conclude with a theoretical discussion questioning the applicability of the theory. Supplemented with this qualitative assessment, I conclude that a quantitative study of the ethnic security dilemma used to explain ethnic violence may not be a viable option for future research in this field.

Better tools for combating insect borne diseases by understanding influences on the fate of common pesticides in paint formulations

Malaria, Zika virus, dengue fever and yellow fever are mosquito transmitted diseases for which a vaccines either do not exists or are not widely available. Prevention control is the main way to reduce their spread, and the use of insecticides constitutes one of the key measures recommended by World Health Organisation. New innovative methods of bringing the insects into contact with the insecticides include the development of insecticidal paint with the advantage of safer application, targeted dosing and significantly reduced risk of collateral damage to humans and the environment. This project will address some of the challenges in developing these solutions. 
Pyrethroids are one of the best insecticides for public health use but suffer from hydrolysis and photo-degradation. Little is known about how their application in paint formulations affects this behavior. At a chemical level the biological activity of the individual enantiomers is determined by the configuration of their chiral centers, so accurately quantifying the enantiomeric composition is critical to tracking potential degradation. The aim of this project is to generate robust methods for a better understanding of the fate of insecticides in complex matrices like paint. Once the nature of the degradation products and the related mechanisms is clear, the formulation can be adjusted to minimize the occurrence of degradation or enhance active ingredient protection. The kinetic analysis of the degradation processes and the interaction/stability studies are best performed in-situ avoiding potentially invasive extraction sample preparation steps, so the powerful tools of advanced NMR spectroscopy will be exploited to characterize these phenomena. The knowledge gained will be used to validate/explain multidisciplinary laboratory biological trial results on mosquitoes and be able to be exploited more widely to other systems and support the research into other compounds for potential deployment in this way.
Infrastructure as a determinant of foreign trade in India and China

The main objective of this paper is to examine the role of infrastructure in enhancing the volume of trade in India and china. It was during the late 1990s both nations tried to globalise more into the world economic system. But the trade performance is not similar in India as well as in china. The present study empirically examines the trade performance is relation to the availability of export and imports. The study is based on time series data from 1990 to 2012. The individual and simultaneous regression analysis is applied to find out the causal effect relationship between infrastructure and trade. The stationary of the data is checked with the help of unit root test. Data has been converted into stationary. From the analysis, it is clear that in China the infrastructure variables are significant and positively related with trade. In India though the infrastructure variables are significant but the R2 and regression coefficient of infrastructure variables on trade is insignificant in all most all the variables.

JAPANESE CORPORATE STRATEGIES ON LOCATION CHOICES OF R&D ACTIVITIES IN CHINA: IDENTIFYING THE ROLE OF KNOWLEDGE SPILLOVERS

The objective of this research is to analyze the geographical distribution of the research and development (R&amp;D) collaboration of Japanese multinational enterprises (MNEs) in China. We analyze location strategies of overseas R&amp;D activities on a regional instead of a national level. We first discuss the linkage of foreign direct investment (FDI) and ensue knowledge spillovers from MNEs to a host country, and further analyze how the knowledge spillovers influence MNEs in making their decisions on location choices in China. Using conditional logit estimation from U.S. patent data, we find that Japanese MNEs are in proximity to the R&amp;D-intensive locations and to the clustering of Japanese MNEs, but have a tendency to keep a distance from R&amp;D-competitive locations that would be endangered by outward knowledge spillovers. In addition, small and medium MNEs are influenced more by location factors, such as R&amp;D and FDI, than large MNEs. So are capital-intensive MNEs than non-capital-intensive MNEs.
AUXILIARY POWER SUPPLY FOR AC POWERED ELECTRONICS

Techniques for supplying auxiliary power to AC powered lighting devices are disclosed. An auxiliary power supply can be used, for example, to provide auxiliary power to lighting control circuitry, an LED driver, or any other electronic lighting device. In some example embodiments, the linear regulator is connected to a switch that is controlled by a control circuit such that the linear regulator operates only when the instantaneous line input voltage is in a certain range where the linear regulator has a somewhat good efficiency. In such cases, when the linear regulator is operating, energy is stored with an auxiliary capacitor connected to the output of the linear regulator.
Amine-Tunable Ruthenium Catalysts for Asymmetric Reduction of Ketones

A series of efficient ruthenium catalysts has been developed for the asymmetric hydrogenation and transfer hydrogenation of ketones with high reactivities and selectivities. The new chiral bisdihydrobenzooxaphosphole (BIBOP)/diamine-ruthenium complexes catalyzed the enantioselective hydrogenation of substrates such as aryl and heteroaryl cyclic and alkyl ketones with substrate/catalyst (S/C) ratios of up to 100,000. The opposite sense of enantioselectivity can be obtained by proper selection of a diamine with a given chirality of the phosphine. The usefulness of the new system has been demonstrated in the asymmetric hydrogenation of a complex synthetic intermediate towards cholesteryl ester transfer protein (CETP) inhibitors at S/C 20,000 on large-scale operation.
Freshwater hotspots of biological invasion are a function of species–pathway interactions

The introduction and spread of aquatic invasive species constitutes a global epidemic that continues to homogenize the world’s aquatic flora and fauna. Species invasions are occurring at an unprecedented scale, yet few centrally organized distributional databases can accurately display location information used to prioritize management efforts within a watershed, region, or political boundary. For particularly harmful groups of invaders such as some freshwater invertebrates, one consequence is that predictive power is limited because current invasion patterns are unknown. We used the Nonindigenous Aquatic Species database of the US Geological Survey to determine current hotspots of invertebrate invasion in the US and compared those patterns with better-documented fish invasions. Invasive freshwater invertebrates were densely clustered in the Laurentian Great Lakes region compared to invasive fish that were concentrated in Florida and the Southwest. However, temporal patterns of fish and invertebrate invasions did not significantly differ. Ballast water was the most important source of invertebrate introductions, whereas fish were more often introduced by stocking, aquaculture, and aquarium release. A centralized database of current species distributions, ideally at the global scale, would greatly inform prevention and mitigation efforts for harmful species invasions.
Experimental and quantum-chemical study of nucleophilic substitution mechanism in berberine

Principal differences in the interaction mechanisms of alkaloid berberine with primary and secondary amines were investigated experimentally and by quantum-chemical calculations according to density functional theory (DFT/B3LYP) with 6-31G** basis set. The nucleophilic substitution of 9-metoxy group with primary amine was shown to proceed through a stage of σ-complex formation and led to 9-alkylamino derivatives of berberine. Analogous substitution with a secondary amine did not occur due to unfavorable thermodynamic parameters. The secondary amine participated in this reaction not as the attacking nucleophile, but rather as a bifunctional catalyst of berberine hydrolysis to berberrubine. The driving force for all these processes was the stabilization of products by hydrogen bonding. Based on the obtained results, we developed a new effective method for the preparation of berberrubine, one of the key intermediates in synthetic transformations of berberine. New 9-monoalkylamino derivatives of berberine containing indole moieties were synthesized.

Sliding window integration scheme for object detection in a radar system

A system and method to detect an object with a radar system involve transmitting two or more sets of linear frequency modulated signals with a gap duration Dg, during which there is no transmission, between each of the two or more sets of the linear frequency modulated signals. Each of the two or more sets of the linear frequency modulated signals defines a sub-frame, and two or more sub-frames defines a frame. The method includes receiving reflections resulting from the linear frequency modulated signals encountering one or more objects in a field of view of the radar system, and processing the reflections to identify the one or more objects. The processing includes performing an on-off Radon transform to correct a phase bias caused by the gap duration during which there is no transmission.
