Authors: Anwar Aneela , Kanwal Qudsia , Akbar Samina , Munawar Aisha , Durrani Arjumand , Hassan Farooq Masood
Published: June 2016

Synthetic nanosized hydroxyapatite (HA) particles (<120 nm) were prepared using a co-precipitation technique by adopting two different routes – one from an aqueous solution of calcium nitrate tetrahydrate and diammonium hydrogen phosphate at pH 10 and the other by using calcium hydroxide and phosphoric acid as precursors at pH 8.5 and reaction temperature of 50°C. The lattice parameters of HA nanopowder were analogous to reference [Joint Committee on Powdered Diffraction Standards (JCPDS)] pattern no. 09-432. No decomposition of HA into other phases was observed even after heating at 1000°C in air for 1 h. This observation revealed the high-temperature stability of the HA nanopowder obtained using co-precipitation route. The effects of preliminary Ca/P molar ratio, precipitation, pH and temperature on the evolution of phase and crystallinity of the nanopowder were systematically examined and optimized. The product was evaluated by techniques such as X-ray-diffraction (XRD), transmission electron microscopy (TEM), Fourier transform infrared (FTIR) and Raman spectroscopy analyses. The chemical structural analysis of the as-prepared HA sample was performed using X-ray photoelectron spectroscopy (XPS). After heat treatment at 1000°C for 1 h and ageing for 15 h, the product was obtained as a phase-pure, highly crystalline HA nanorods.
IUPAC/CITAC Guide: Classification, modeling and quantification of human errors in a chemical analytical laboratory (IUPAC Technical Report)
Authors: Kuselman Ilya , Pennecchi Francesca
Published: June 2016

The classification, modeling, and quantification of human errors in routine chemical analysis are described. Classifications include commission errors (mistakes and violations) and omission errors (lapses and slips) in different scenarios at different steps of the chemical analysis. A Swiss cheese model is used to characterize error interaction with a laboratory quality system. The quantification of human errors in chemical analysis, based on expert judgments, i.e. on the expert(s) knowledge and experience, is applied. A Monte Carlo simulation of the expert judgments was used to determine the distributions of the error quantification scores (scores of likelihood and severity, and scores of effectiveness of a laboratory quality system against the errors). Residual risk of human error after the error reduction by the laboratory quality system and consequences of this risk for quality and measurement uncertainty of chemical analytical results are discussed. Examples are provided using expert judgments on human errors in pH measurement of groundwater, multi-residue analysis of pesticides in fruits and vegetables, and elemental analysis of geological samples by inductively coupled plasma mass spectrometry.
IonLab – a remote-controlled experiment for academic and vocational education and training on extraction chromatography and ion exchange
Authors: Schulz Wolfgang , Fournier Claudia , Vahlbruch Jan-Willem , Walther Clemens
Published: June 2016

As a major contribution to modern web-based education and training in nuclear chemistry we have built and operated a remote-controlled experiment – IonLab – as part of the integrated EUFP7 project CINCHII. The setup is suitable for teaching basics on extraction chromatography and ion exchange using radionuclides. We describe separation of the beta emitting nuclides Sr-90 and Y-90 followed by radiometric detection, but the experiment is easily adapted to other separation schemes. This approach is aimed at institutions in academic or vocational education who need to convey the skills of handling radioactive (or otherwise dangerous, e.g. biotoxic) substances without appropriately licensed laboratory space for teaching. This camera-monitored remote controlled lab experiment has proved to be much closer to a real hands-on training and superior to a mere computer simulation.
Entropy Production Within a Pulsed Bose–Einstein Condensate
Authors: Heinisch Christoph , Holthaus Martin
Published: June 2016

We suggest to subject anharmonically trapped Bose–Einstein condensates to sinusoidal forcing with a smooth, slowly changing envelope, and to measure the coherence of the system after such pulses. In a series of measurements with successively increased maximum forcing strength, one then expects an adiabatic return of the condensate to its initial state as long as the pulses remain sufficiently weak. In contrast, once the maximum driving amplitude exceeds a certain critical value there should be a drastic loss of coherence, reflecting significant heating induced by the pulse. This predicted experimental signature is traced to the loss of an effective adiabatic invariant, and to the ensuing breakdown of adiabatic motion of the system’s Floquet state when the many-body dynamics become chaotic. Our scenario is illustrated with the help of a two-site model of a forced bosonic Josephson junction, but should also hold for other, experimentally accessible configurations.
Mundo tradicional y convalecencia metafísica
Authors: Ibarra Ibarra Jorge Ignacio
Published: June 2016

La tradición tiene un amplio abordaje en la filosofía, en Aristóteles por ejemplo, es reconocida como fuente de explicaciones cosmológicas y éticas. La edad media la identifica con la autoridad divina. De esta manera el presente trabajo busca explorar la cuestión de la tradición, no solamente desde su genealogía histórica, sino vista como un conjunto de prácticas sociales y maneras de entender el mundo que sobreviven en un entorno complejo de tensión entre laicismo y vuelta del fundamentalismo religioso.
Impaired growth and intracranial calcifications in autosomal dominant hypocalcemia caused by a GNA11 mutation
Authors: Tenhola Sirpa , Voutilainen Raimo , Reyes Monica , Toiviainen-Salo Sanna , Jüppner Harald , Mäkitie Outi
Published: June 2016

Objective

Autosomal dominant hypocalcemia (ADH) is characterized by hypocalcemia and inappropriately low PTH concentrations. ADH type 1 is caused by activating mutations in the calcium-sensing receptor (CASR), a G-protein-coupled receptor signaling through α11 (Gα11) and αq (Gαq) subunits. Heterozygous activating mutations in GNA11, the gene encoding Gα11, underlie ADH type 2. This study describes disease characteristics in a family with ADH caused by a gain-of-function mutation in GNA11.

Design

A three-generation family with seven members (3 adults, 4 children) presenting with ADH.

Methods

Biochemical parameters of calcium metabolism, clinical, genetic and brain imaging findings were analyzed.

Results

Sanger sequencing revealed a heterozygous GNA11 missense mutation (c.1018G>A, p.V340M) in all seven hypocalcemic subjects, but not in the healthy family members (n=4). The adult patients showed clinical symptoms of hypocalcemia, while the children were asymptomatic. Plasma ionized calcium ranged from 0.95 to 1.14mmol/L, yet plasma PTH was inappropriately low for the degree of hypocalcemia. Serum 25OHD was normal. Despite hypocalcemia 1,25(OH)2D and urinary calcium excretion were inappropriately in the reference range. None of the patients had nephrocalcinosis. Two adults and one child (of the two MRI scanned children) had distinct intracranial calcifications. All affected subjects had short stature (height s.d. scores ranging from −3.4 to −2.3 vs −0.5 in the unaffected children).

Conclusions

The identified GNA11 mutation results in biochemical abnormalities typical for ADH. Additional features, including short stature and early intracranial calcifications, cosegregated with the mutation. These findings may indicate a wider role for Gα11 signaling besides calcium regulation.

Historia, memoria y palabra: propuesta y experiencia de un espacio académico en Educación Superior
Authors: Polanía González Javier , Rivera Venegas Juan Carlos
Published: June 2016

 

Este texto presenta la reflexión realizada por un grupo de profesores del Departamento de Formación Lasallista –unidad académica que propicia la formación integral de la comunidad universitaria a partir de la profundización, transmisión y generación de conocimientos que cuestionen, iluminen, dialoguen y aporten soluciones para las actuales problemáticas del mundo– en torno a una asignatura en pregrado, común a todos los programas, dirigida a repensar el mensaje religioso desde el enfoque de la historia, la memoria y la palabra. 

El espacio pretende hacer un mayor énfasis en la búsqueda de sentido dando valor a la memoria, utilizando los avances que se han producido en torno a la discusión sobre esta en los diversos contextos de las ciencias sociales, teológicas y del escenario político, particularmente las masacres cometidas en el conflicto armado colombiano, para colocarlos en juego a propósito de construir una propuesta académica que desde la construcción del sentido propicie la elaboración de narrativas personales y sociales de vida y de creencia vinculadas a la constitución de sujetos humanistas, democráticos y abiertos al diálogo interreligioso e intercultural. La asignatura se desarrolla semestralmente desde el segundo semestre de 2011; se presentan logros, dificultades y retos de esta experiencia que ha contribuido a desarrollar procesos de sensibilización en los jóvenes de diferentes programas y facultades.

BLIMP-1/BLMP-1 and Metastasis-Associated Protein Regulate Stress Resistant Development in Caenorhabditis elegans
Authors: Hyun Moonjung , Kim Jeongho , Dumur Catherine , Schroeder Frank C , You Young-Jai
Published: June 2016

Environmental stress triggers multilevel adaptations in animal development that depend in part on epigenetic mechanisms. In response to harsh environmental conditions and pheromone signals, Caenorhabditis elegans larvae become the highly stress-resistant and long-lived dauer. Despite extensive studies of dauer formation pathways that integrate specific environmental cues and appear to depend on transcriptional reprogramming, the role of epigenetic regulation in dauer development has remained unclear. Here we report that BLMP-1, the BLIMP-1 ortholog, regulates dauer formation via epigenetic pathways; in the absence of TGF-β signaling (in daf-7 mutants), lack of blmp-1 caused lethality. Using this phenotype, we screened 283 epigenetic factors, and identified lin-40, a homolog of metastasis-associate protein 1 (MTA1) as an interactor of BLMP-1. The interaction between LIN-40 and BLMP-1 is conserved because mammalian homologs for both MTA1 and BLIMP-1 could also interact. From microarray studies, we identified several downstream target genes of blmp-1: npr-3, nhr-23, ptr-4, and sams-1. Among them S-adenosyl methionine synthase (SAMS-1), is the key enzyme for production of SAM used in histone methylation. Indeed, blmp-1 is necessary for controlling histone methylation level in daf-7 mutants, suggesting BLMP-1 regulates the expression of SAMS-1, which in turn may regulate histone methylation and dauer formation. Our results reveal a new interaction between BLMP-1/BLIMP-1 and LIN-40/MTA1, as well as potential epigenetic downstream pathways, whereby these proteins cooperate to regulate stress-specific developmental adaptations.
Editing Transgenic DNA Components by Inducible Gene Replacement in Drosophila melanogaster
Authors: Lin Chun-Chieh , Potter Christopher J
Published: June 2016

Gene conversions occur when genomic double-strand DNA breaks (DSBs) trigger unidirectional transfer of genetic material from a homologous template sequence. Exogenous or mutated sequence can be introduced through this homology-directed repair (HDR). We leveraged gene conversion to develop a method for genomic editing of existing transgenic insertions in Drosophila melanogaster. The clustered regularly-interspaced palindromic repeats (CRISPR)/Cas9 system is used in the homology assisted CRISPR knock-in (HACK) method to induce DSBs in a GAL4 transgene, which is repaired by a single-genomic transgenic construct containing GAL4 homologous sequences flanking a T2A-QF2 cassette. With two crosses, this technique converts existing GAL4 lines, including enhancer traps, into functional QF2 expressing lines. We used HACK to convert the most commonly-used GAL4 lines (labeling tissues such as neurons, fat, glia, muscle, and hemocytes) to QF2 lines. We also identified regions of the genome that exhibited differential efficiencies of HDR. The HACK technique is robust and readily adaptable for targeting and replacement of other genomic sequences, and could be a useful approach to repurpose existing transgenes as new genetic reagents become available.

Abstract: The independence of the judicial power is a must and an absolute guarantee given to the judge. Judges should be independent of any pressures that may disturb his contemplation in making a decision that determines one's fate. The independence of the key is not only focused on how the pressure from outside in order to judge themselves neutral decision, but also expanded the independence of a judge rules that govern self itself. Judges can not be equated with the State Civil Apparatus employees, because the position is different judges. Placement of this is not specifically regulated in the country of Indonesia. It could be argued that these ideals are still owed by the constitution of this country when compared to other law enforcement officials who already have the legality of their own profession as prosecutors, police and lawyers.Abstrak: Independensi kekuasaan kehakiman merupakan garansi yang harus dan mutlak diberikan kepada Hakim.

Video Recording as a Tool for Assessing Children's Everyday Use of Features Targeted in Phonological Intervention
Authors: Samuelsson Christina , Lundeborg Inger , Plejert Charlotta
Published: June 2016

The last decades, speech and language pathology services have been subject to changes, and there has been a growing demand for intervention activities to be effective and evidence-based. The aim of the present study was to investigate if and how video recording can be used to assess the use of features targeted in phonological intervention, in everyday talk by children with LI. Three five-year-old girls with phonological problems participated in the study, and data consist of video recordings of intervention sessions and of interaction at home. Three different paths of development were identified: Some targeted speech sounds are displayed in everyday interaction; Targeted speech sound is present in intervention-like activity; No displays of targeted sounds. The results of the present study clearly demonstrate that the use of video recordings, transcriptions and analysis of interaction outside of the clinical setting contribute important information that may guide planning, goal-setting and evaluation of intervention.
Intact reported speech use in traumatic brain injury
Authors: Duff Melissa , Covington Natalie
Published: June 2016

Communication impairments following traumatic brain injury (TBI) are notoriously difficult to capture and characterize. We sought to examine social communication abilities in adults with TBI by evaluating their use of reported speech while interacting with a clinician in the context of the Mediated Discourse Elicitation Protocol. We found that participants with TBI were nearly indistinguishable in the frequency, types, and temporal domains of their reported speech use from case-matched healthy comparison participants. Finding aspects of interactional and communicative behaviour that are not affected by TBI in some individuals, or groups of individuals, provides an important opportunity to leverage the hallmark heterogeneity typical in TBI to consider how the status of various aspects of communication may cluster together and may inform, or even predict, communicative outcome at the individual or subgroup level. Efforts to link communicative success to specific cognitive and neural profiles and to social and communicative outcomes are warranted.

Practical tips for undertaking a medical education research project at undergraduate level: Recommendations for both students and supervisors.
Authors: Barnard James , Ledger Alison
Published: June 2016

This article was migrated. The article was not marked as recommended. Many undergraduate medical programmes now require students to develop research and medical students are increasingly choosing to undertake medical education projects at undergraduate level. As medical education research often requires different ways of thinking about knowledge and research compared with biomedical disciplines, undergraduate medical education research can be challenging for students and supervisors alike. This paper aims to address a gap in the literature, by providing recommendations for both students and supervisors involved in undergraduate medical education research. Our practical tips are based upon reflections and insights from an undergraduate student who undertook a medical education research project and an experienced undergraduate research supervisor. The importance of good organisational, time management and communication skills are highlighted. Students should recognise and make the most of the unique learning opportunities that are present when undertaking a medical education research project and supervisors should be attentive and supportive of their individual students' needs.
Occupational Choice, Retirement, and the Effects of Disability Insurance
Authors: Jacobs Lindsay
Published: June 2016

There is much variation in the physical requirements across occupations, giving rise to great differences in later-life productivity, disability risk, and the value of Social Security Disability Insurance (SSDI). In this paper, I look at how such differences across occupations affect initial career choice as well as the extent to which SSDI, which insures shocks to productivity due to disability, prompts more people to choose physically intense occupations. Using data from the Health and Retirement Study (HRS) and the Current Population Survey (CPS), I estimate a dynamic model of occupational choice and retirement with heterogeneous agents and equilibrium effects on earnings across occupations. I document the differences between blue-collar and white-collar occupations in the effects of declining health and disability on productivity, which affects labor supply in later life and, in the context of a life-cycle model, influences the occupation decision. Through counterfactual exercises, I show that the additional disability risk in blue-collar jobs relative to white-collar jobs is equivalent to an additional six percentage point reduction in lifetime consumption and that the absence of SSDI, which insures some of this risk, would be equivalent to, respectively, a twelve and seven percent reduction in consumption for those in blue- and white- collar jobs. Furthermore, I find that the presence of SSDI results in three percent more individuals choosing blue-collar occupations, which is comparable to the effect on occupation selection resulting from an eight-percent increase in blue-collar earnings. This overall effect, however, masks the importance of the selection of less risk-averse individuals into blue-collar jobs and the equilibrium effects on wages; earnings for the most risk-averse type would have to be nearly fifteen percent greater to choose blue-collar occupations in the absence of SSDI.

Ao conceber-se esta pesquisa, levou-se em consideração que cada ser humano aprende do seu modo pessoal e único, portanto, a proposta é pensar os videogames na sua relação com o Paradigma da Complexidade. Esta pesquisa teve como objetivo proporcionar um ambiente de encontro com diversos jogos de videogame, buscando instaurar a experimentação do novo, a abertura para o conhecer, ao habitar espaços inventivos, que valorizam a plasticidade e flexibilidade. Trata-se de uma pesquisa qualitativa, pois se propôs a trabalhar com os aspectos subjetivos como uma dimensão inseparável do conhecer. Foram 8 sujeitos de pesquisa – adolescentes – com os quais foram realizados 15 encontros, nos quais os mesmos estiveram em contato com diversos jogos de videogame. Foram utilizados diários de bordo para o registro das vivências, ancorados na metodologia cartográfica para tratamento dos registros. Os videogames propiciaram espaços para a emergência de diferentes formas de vivenciar a narrativa. Apesar de os jogos serem pré-moldados, os percursos produzidos, assim como as produções simbólicas frente ao contexto do jogo foram individuais. Jogar videogame relacionou-se ao posicionamento criador, de escrever as circunstâncias sob as quais as ações do jogo refletiram nas experiências vivenciadas pelo jogador.

O projeto de pesquisa: “Qualidade Visual do Patrimônio Arquitetônico Eclético na Paisagem Urbana da Área Central de Santa Cruz do Sul: O Impacto das Mídias Exteriores” teve como principal objetivo realizar um diagnóstico referente ao impacto visual causado pelos diferentes elementos de publicidade utilizados nas edificações do período eclético da arquitetura. Parte-se dos pressupostos de que os elementos de publicidade, em seu excesso, ocasionam a perda da legibilidade das edificações patrimoniais pela população. Por outro lado, as alterações de identidade visual dos imóveis ocorrem também em conjunto com outros processos como os de sua readequação funcional e descaracterização física. Este artigo compreende uma descrição sintética da metodologia utilizada para desenvolver a pesquisa, bem como os principais resultados finais obtidos ao longo dos dois anos de estudo (2012 e 2013) e que estão relacionados ao uso atual e original das edificações, ao conceito de legibilidade (integridade física e estado geral de conservação externa) das obras e a avaliação geral dos diferentes níveis de impactos causados pelas mídias.

PARTICIPAÇÃO DOS MASTÓCITOS NO REPARO TECIDUAL E EM LESÕES INFLAMATÓRIAS BUCAIS – UMA REVISÃO DE LITERATURA
Authors: Correia Kariza Vargens , Medrado Alena Peixoto
Published: June 2016

Os mastócitos são células móveis que contêm grânulos, derivados da medula óssea e estão amplamente distribuídos nos tecidos conjuntivos participando ativamente das respostas imunológicas. O envolvimento destas células tem sido demonstrado nos processos de inflamação, angiogênese e fibrose, nos quais atuam por meio de seus produtos de secreção. O objetivo dessa revisão de literatura é abordar o envolvimento dos mastócitos nos fenômenos biológicos que integram o contexto do reparo tecidual, a exemplo da vasodilatação, angiogênese e fibrose, com ênfase na caracterização do perfil destas células em lesões inflamatórias bucais. Apesar de poucos estudos contemplarem a participação dos mastócitos em lesões orais, alguns trabalhos têm demonstrado que tais células estão envolvidas na patogênese de lesões periapicais, ulcerações aftosas recorrentes, cistos odontogênicos, entre outros. O avanço do conhecimento acerca do mecanismo de ação dessas células tem estimulado o desenvolvimento de terapias cujo alvo principal é a regulação dos mediadores químicos liberados pelos mastócitos. Logo, espera-se que através de novas investigações, as desordens inflamatórias da cavidade oral e outras patologias que exibam mastócitos em seu interstício, possam ser melhor compreendidas, em especial no que diz respeito ao papel biológico que estas células poderiam exercer nestas lesões.
O USO DA TERAPIA LASER DE BAIXA INTENSIDADE APÓS EXODONTIA DE TERCEIROS MOLARES: REVISÃO DE LITERATURA
Authors: Pedreira Amanda Affonsêca , Sá Maíra , Medrado Alena Peixoto
Published: June 2016

A exodontia é um procedimento odontológico que envolve trauma aos ossos e tecidos moles. A gravidade da intervenção, a localização das unidades dentárias, a textura tecidual e o grau de destruição óssea são váriaveis que interferem na presença ou ausência de efeitos pós-operatórios deletérios, em particular no que diz respeito à exodontia de terceiros molares. A terapia laser de baixa intensidade (LLLT) tem sido usada clinicamente para acelerar a cicatrização de feridas e controlar a dor. No entanto, embora a laserterapia passa a ser indicada após exodontias de terceiros molares, seu uso tem sido raramente prescrito. O objetivo desse artigo é fazer uma revisão da literatura sobre o uso da laserterapia durante o período pós-operatório da remoção cirúrgica de terceiros molares.

Metodologia: Numa amostragem final de cinquenta e três indivíduos, aleatoriamente divididos nos grupos teste (Sanativo®), CPA (Malvatricin®), CPB (Clorexidina) e Controle (Solução fisiológica). Os pacientes foram instruídos a fazer bochechos três vezes ao dia durante 07 dias. Foram considerados os parâmetros: tamanho da ferida e aspecto inflamatório visual em três tempos experimentais (pós-operatório imediato, 48 horas e 07 dias após a intervenção). O teste de Tukey com nível de significância de 5% foi realizado, além da análise descritiva visual. Resultado: Os resultados não evidenciaram incremento de efeito do uso do Sanativo® sobre os parâmetros avaliados, não comprovando, portanto, benefício adicional no uso do referido medicamento. Conclusão: O uso do Sanativo® não apresentou benefício adicional na redução do tamanho da ferida, não tendo sido, portanto comparável à clorexidina, que confirmou a sua eficácia superior.
OSTEOMIELITE ASSOCIADA À DISPLASIA CEMENTO-ÓSSEA FLORIDA: RELATO DE CASO
Authors: Nogueira Neto João Nunes , Ayres Moreira Carlos Vinícius , Morais Godoy Figueiredo Leonardo , Ramos de Souza Samara , Carneiro Júnior Braúlio
Published: June 2016

A Displasia Cemento-Óssea Florida (DCOF) é uma lesão fibro-óssea, não neoplásica, onde ocorre a substituição do tecido ósseo por tecido conjuntivo fibroso nos maxilares. Possui predileção por pacientes do gênero feminino, melanodermas e de meia idade, apresentando-se como uma condição rara que afeta principalmente a mandíbula bilateralmente, podendo ocorrer em áreas dentadas ou edêntulas. Sua etiologia é desconhecida, embora exista hipótese relacionada à origem no ligamento periodontal, já que se baseia na formação de múltiplas áreas de osso ou cemento acelular envolvidos por tecido fibroso. A DCOF torna-se sintomática quando associada à osteomielite, principal fator agravante desta patologia. O diagnóstico diferencial, baseado nos achados clínicos e radiográficos, torna-se primordial para a direção do tratamento, que na maioria dos casos é assintomático e de prognóstico previsível.

O objetivo desse estudo foi avaliar utilizando a diafanização, a capacidade de limpeza das paredes de canais radiculares achatados preparados com três diferentes instrumentos. Foram selecionados 30 incisivos inferiores que após abertura coronária e odontometria tiveram os canais preenchidos com tinta nanquim, em seguida foram divididos aleatoriamente em três grupos de 10 dentes cada, de acordo com o instrumento utilizado no preparo: Grupo 1 – instrumentação com limas manuais; Grupo 2 – instrumentação com limas rotatórias ProTaper Universal; Grupo 3 – instrumentação com limas rotatórias iRace. Após a instrumenta- ção, os dentes foram diafanizados e avaliados quanto a capacidade de limpeza, analisando-se a quantidade de paredes dentinárias em que a tinta nanquim não foi removida. Ao se realizar o teste de Kruskal Wallis (p>0,05) não foram observadas diferenças estatisticamente significantes entre os grupos, quanto a média aritmética dos escores nos terços cervical, médio e apical. Nenhum dos instrumentos utilizados no preparo biomecânico de canais radiculares achatados foi capaz de realizar uma completa limpeza das paredes dentinárias.

Published: June 2016

Present paper investigates the effect of changes in investment and taxes on the economic growth. Using quarterly data from 1997 to 2008 for Armenian economy we showed that the effect of the increase in investment and taxes on real GDP is positive or negative. The interrelation between GDP and investment is studied using the approach based on the development of VAR model. The analysis of this model allowed studying the behaviour of curves representing GDP and investment. In fact, we showed that the GDP curve is stable and oscillated and the investment curve is stable and none oscillated. Furthermore, we evaluated the impact of investment changes by 1% on the GDP growth which was equal to 0.4%. Then the model representing interrelation between GDP and taxes allowed evaluating the effect of tax changes by 1%. The findings allowed evaluating the effect of growth in investment and taxes depending on the GDP growth rate. Simultaneously, VAR system allowed evaluating the changes in GDP on the investment growth.
