Marine phytoplankton stoichiometry mediates nonlinear interactions between nutrient supply, temperature, and atmospheric CO2
Authors: Moreno Allison R. , Hagstrom George I. , Primeau Francois W. , Levin Simon A. , Martiny Adam C.
Published: May 2018

Abstract. Marine phytoplankton stoichiometry links nutrient supply to marine carbon export. Deviations of phytoplankton stoichiometry from Redfield proportions (106C : 1P) could therefore have a significant impact on carbon cycling, and understanding which environmental factors drive these deviations may reveal new mechanisms regulating the carbon cycle. To explore the links between environmental conditions, stoichiometry, and carbon cycling, we compared four different models of phytoplankton C : P: a fixed Redfield model, a model with C : P given as a function of surface phosphorus concentration (P), a model with C   P given as a function of temperature, and a new multi-environmental model that predicts C : P as a function of light, temperature, and P. These stoichiometric models were embedded into a five-box ocean circulation model, which resolves the three major ocean biomes (high-latitude, subtropical gyres, and tropical upwelling regions). Contrary to the expectation of a monotonic relationship between surface nutrient drawdown and carbon export, we found that lateral nutrient transport from lower C : P tropical waters to high C : P subtropical waters could cause carbon export to decrease with increased tropical nutrient utilization. It has been hypothesized that a positive feedback between temperature and pCO2, atm will play an important role in anthropogenic climate change, with changes in the biological pump playing at most a secondary role. Here we show that environmentally driven shifts in stoichiometry make the biological pump more influential, and may reverse the expected positive relationship between temperature and pCO2, atm. In the temperature-only model, changes in tropical temperature have more impact on the Δ pCO2, atm (∼ 41 ppm) compared to subtropical temperature changes (∼ 4.5 ppm). Our multi-environmental model predicted a decline in pCO2, atm of ∼ 46 ppm when temperature spanned a change of 10 °C. Thus, we find that variation in marine phytoplankton stoichiometry and its environmental controlling factors can lead to nonlinear controls on pCO2, atm, suggesting the need for further studies of ocean C : P and the impact on ocean carbon cycling.
Reviews and syntheses: Revisiting the boron systematics of aragonite and their application to coral calcification
Authors: DeCarlo Thomas M. , Holcomb Michael , McCulloch Malcolm T.
Published: May 2018

Abstract. The isotopic and elemental systematics of boron in aragonitic coral skeletons
have recently been developed as a proxy for the carbonate chemistry of the
coral extracellular calcifying fluid. With knowledge of the boron isotopic
fractionation in seawater and the B∕Ca partition coefficient (KD)
between aragonite and seawater, measurements of coral skeleton δ11B
and B∕Ca can potentially constrain the full carbonate system. Two sets
of abiogenic aragonite precipitation experiments designed to quantify KD
have recently made possible the application of this proxy system. However,
while different KD formulations have been proposed, there has not yet been
a comprehensive analysis that considers both experimental datasets and
explores the implications for interpreting coral skeletons. Here, we evaluate
four potential KD formulations: three previously presented in the
literature and one newly developed. We assess how well each formulation
reconstructs the known fluid carbonate chemistry from the abiogenic
experiments, and we evaluate the implications for deriving the carbonate
chemistry of coral calcifying fluid. Three of the KD
formulations performed similarly when applied to abiogenic aragonites
precipitated from seawater and to coral skeletons. Critically, we find that
some uncertainty remains in understanding the mechanism of boron elemental
partitioning between aragonite and seawater, and addressing this question
should be a target of additional abiogenic precipitation experiments. Despite
this, boron systematics can already be applied to quantify the coral
calcifying fluid carbonate system, although uncertainties associated with the
proxy system should be carefully considered for each application. Finally, we
present a user-friendly computer code that calculates coral calcifying fluid
carbonate chemistry, including propagation of uncertainties, given inputs of
boron systematics measured in coral skeleton.
Daily GRACE gravity field solutions track major flood events in the Ganges–Brahmaputra Delta
Authors: Gouweleeuw Ben T. , Kvas Andreas , Gruber Christian , Gain Animesh K. , Mayer-Gürr Thorsten , Flechtner Frank , Güntner Andreas
Published: May 2018

Abstract. Two daily gravity field solutions based on observations from the
Gravity Recovery and Climate Experiment (GRACE) satellite mission are
evaluated against daily river runoff data for major flood events in the
Ganges–Brahmaputra Delta (GBD) in 2004 and 2007. The trends over periods of a
few days of the daily GRACE data reflect temporal variations in daily river
runoff during major flood events. This is especially true for the larger
flood in 2007, which featured two distinct periods of critical flood level
exceedance in the Brahmaputra River. This first hydrological evaluation of
daily GRACE gravity field solutions based on a Kalman filter approach
confirms their potential for gravity-based large-scale flood monitoring. This
particularly applies to short-lived, high-volume floods, as they occur in the
GBD with a 4–5-year return period. The release of daily GRACE gravity field
solutions in near-real time may enable flood monitoring for large events.

Con la convicción de que la sociología de la educación puede contribuir a la mejora de nuestras sociedades y de su necesaria transformación hacia el decrecimiento (Taibo, 2017), se presenta uno de los principales resultados obtenidos a través de la medición en escalas tipo Likert de las respuestas dadas por 108 jóvenes varones y mujeres veinteañeros de nuestros respectivos entornos culturales (A Coruña y Mallorca), que voluntaria y anónimamente respondieron a dos cuestionarios elaborados para recoger sus opiniones en torno a una de nuestras metáforas zombie (Lizcano, 2006) más actuales como es la de la cibercultura y, también, cómo ésta ha repercutido en el cambio de sus hábitos a través del  uso de tiempos de su vida cotidiana en los últimos cinco años. El análisis de varianza ha revelado que la variable género marca diferencias significativas en la comprensión del fenómeno de la cibercultura, pese a su global hegemonía.
Discurso ambiental e a apropriação da natureza: o caso do Complexo Industrial Portuário de Suape – Pernambuco – Brasil
Authors: Nunes Souza da Silva Dweison , Torres Aguiar Gomes Edvânia
Published: May 2018

Na contemporaneidade, a questão ambiental está na ordem do dia de muitas corporações, sejam públicas, privadas ou “parceiras” – o que é mais comum, mesmo não sendo oficialmente. Aparentemente compartilham objetivos convergentes: suas atividades intimamente correlacionadas a imperativos socioambientais, pelo menos no discurso. Nesse sentido, este artigo busca analisar a efetividade do discurso socioambiental promovido pelo Complexo Industrial Portuário de Suape – papel do Estado, enquanto políticas públicas ambientais, acerca da conservação/ preservação das Unidades de Conservação e Áreas de Preservação Permanente. Para tanto, são revisitados e abordados, dialeticamente, referenciais teórico-metodológicos e publicações oficiais por meio de pesquisa documental/ bibliográfica. Observa-se que o discurso ambiental se apresenta contraditório, uma vez que o CIPS aparentemente apresenta suas atividades regradas por políticas públicas aliadas à sustentabilidade; todavia, historicamente, atua também num contexto de legitimação através de políticas públicas e de atividades estritamente econômicas, inserido, pois, numa lógica de exploração e apropriação dessa natureza que teoricamente se almejaria preservar.Palavras-chave: Suape, discurso ambiental, políticas públicas, conservação/ preservação.
Validação da expressão aproximada da rigidez secante adimensional (Kappa) para concreto de alta resistência [Validation of non-dimensional secant stiffness (kappa) approximated expression for high strength concrete]
Authors: Licht Fortes Gustavo , Carlos Della Bella João , Leopoldo e Silva França Ricardo
Published: May 2018

Concretos de alta resistência (CAR) estão inseridos no grupo II de resistência e possuem fck superior a 50 MPa. Eles possuem curvas tensão-deformação com limites distintos daqueles convencionados como concretos de resistência normal. Por isso, o uso da rigidez secante adimensional apresentada pela norma brasileira de concreto armado – NBR6118 (ABNT, 2014) – necessita de validação para CAR. Para essa validação da expressão que consta na norma brasileira para CAR, foram analisadas disposições de armadura consideradas mais desfavoráveis para a resistência (altos valores de d’/h), com várias taxas mecânicas de armadura. Foram comparados os momentos máximos de 1ª ordem que poderiam ser aplicados na seção caso se considerasse a rigidez kappa a partir do diagrama momento-curvatura, com aqueles momentos obtidos considerando a rigidez kappa aproximada por expressão normativa. Em apenas 4,26% dos 5.840 casos analisados, o valor aproximado resultou maior que o valor real. A maior diferença entre os valores de máximos momentos de primeira ordem obtidos por meio da rigidez adimensional real e aproximada foi de 7,27%, o que pode ser considerado aceitável. Dessa forma a expressão aproximada da rigidez kappa prescrita pela NBR6118 (ABNT, 2014) também é válida para CAR.
Abstract
High strength concretes (HSC) are presented in group II of resistance and have compression strength greater than 50 MPa at 28 days. They have stress-strain curves with different limits from those referred as normal resistance concretes. Therefore, the use of the non-dimensional secant stiffness presented by the Brazilian Code of Reinforced Concrete - NBR6118 (ABNT, 2014) - needs validation for HSC. Unfavorable dispositions of steel bar reinforcement (high values of d '/ h), with a several mechanical rates of reinforcement, were analyzed for validation of the expression that appears in the Brazilian Code for HSC. It was compared the maximum moment of 1st order that could be applied in the section if the kappa stiffness was considered from the moment-curvature diagram, with those moments obtained with the normative expression for kappa stiffness. The approximate value was greater than the   real value in only 4.26% of the 5840 cases analyzed. The greatest difference between the values of maximum first-order moments obtained by the real and the approximate non-dimensional stiffness was 7.27%, which can be considered acceptable. Thus the approximate expression of the kappa stiffness prescribed by NBR6118 (ABNT,  2014) is also valid for HSC.

Published: May 2018

No momento de instabilidade econômica em que se encontra o país, ações que minimizem os gastos e que aumentem a produtividade na construção civil visando ao desenvolvimento sustentável dos meios de produção estão cada vez mais sendo solicitadas. Com o intuito de realizar um diagnóstico da disposição, organização e práticas nos canteiros de obra da região do Crajubar, foram estudadas dez construções em execução na região. A amostra selecionada contemplava edificações horizontais e verticais, com finalidade de uso comercial, residencial e mista. Os dados foram obtidos a partir do método de diagnóstico que consiste na aplicação de uma lista de verificação (check-list) padronizada, que contemplava três grupos a serem analisados: instalações provisórias, segurança na obra e movimentação e armazenagem de materiais. Para a visualização e identificação de falhas nos canteiros foi feito um registro fotográfico de itens pré-determinados. De posse das informações coletadas foram atribuídas notas para os grupos, calculada a nota global (que é a média aritmética das notas de grupo) e as obras foram distribuídas em quatro categorias: ótimas, boas, regulares e ruins. As obras horizontais obtiveram as piores notas, entre 4,01 e 6, enquanto as obras verticais que apresentavam políticas de gestão de qualidade se destacaram com as melhores notas, entre 8,01 e 10. O tipo de obra foi o fator que mais influenciou na qualidade dos canteiros de obras avaliados no Crajubar cearense.
Abstract
At a time of economic instability in the country, actions that minimize expenditures and increase productivity in civil construction aimed at the sustainable development of the means of production are increasingly being requested. In order to make a diagnosis of the layout, organization and practices in the construction sites of the Crajubar region, ten constructions were studied in the region. The sample selected included horizontal and vertical buildings, for commercial, residential and mixed use. The data were obtained from the diagnostic method, which consists of the application of a standardized checklist, which included three groups to be analyzed: temporary installations, handling and storage of materials. Along with this list, a photographic record of predetermined items was made for the visualization and identification of defects in the construction. From the information collected, the group notes and a global grade (the arithmetic mean of the group notes) were assigned and the works were distributed into four categories: great, good, regular and bad. The horizontal construction obtained the worse notes, between 4.01 and 6, while the vertical construction that presented policies of quality management stood out with the best notes, between 8,01 and 10. The type of construction was the factor that most influenced the quality of the construction sites evaluated in Crajubar cearense.

¿Cómo puede la tecnología contribuir a la integración de alumnos con necesidades especiales a la enseñanza y aprendizaje de las matemáticas en aulas inclusivas?
Authors: Sala Núria Rosich
Published: May 2018

Os avanços tecnológicos e em especial os digitais, tem contribuído de forma importante no ensino e aprendizagem da matemática. O uso da tecnologia não é novo, há muito tempo, a utilização das “calculadoras” já havia sido incorporada nas salas de aula. Posteriormente, com o desenvolvimento dos ambientes digitais, favoreceu-se a criação de software específico, para o aluno sem alguma necessidade educativa especial. A criação de programas concretos e de aplicação para alunos com necessidades educativas especiais inseridos em salas de aula inclusivas ocorreram muito mais recente. Entres os diversos software que podemos encontrar para estes alunos podemos citar: cibervoz, infovox etc., para alunos cegos. Apresentamos, aqui, a rápida evolução que tem experimentado a criação e o uso das chamadas “novas tecnologias” TIC (Tecnologias de Informação e Comunicação) no ensino e aprendizagem

da matemática nos níveis obrigatórios em aulas inclusivas. Mostraremos também como nosso grupo tem evoluído na inserção das novas metodologias para aulas inclusivas. E de igual forma exporemos as distintas investigações que realizamos com os ambientes de

aprendizagem digital para alunos com necessidades especiais (surdos, cegos etc.) e que nos mostraram a eficácia deles.

Published: May 2018

A qualidade da educação escolarizada requer o engajamento dos profissionais nas escolas em um processo formativo contínuo em que o Mestrado Profissional em Ensino se apresenta como um possível percurso. Nessa perspectiva formativa, os produtos educacionais são apresentados

como elementos relevantes para a qualidade das práticas pedagógicas em que são inseridos e para o próprio processo formativo do pesquisador. O problema, diante disso, refere-se às contribuições que um produto educacional pode trazer para a qualidade da prática pedagógica.

Com base na problemática, o objetivo do estudo foi identificar quais contribuições os produtos educacionais do Mestrado Profissional em Ensino (PPGEN) oferecem para as práticas pedagógicas. Tratou-se de uma pesquisa qualitativa, descritiva, de caráter bibliográfico, na qual se contemplou quatorze produtos educacionais e dissertações de pós-graduação defendidas no ano de 2015. Verificou-se que as contribuições para as práticas pedagógicas relacionam-se à tipologia do produto educacional, à temática abordada em cada um, ao público-alvo e ao

processo formativo dos pesquisadores que elaboraram cada produto. Devem ser incentivados estudos dessa natureza que, além da abordagem sobre as contribuições pedagógicas, analisem o processo de divulgação dos produtos educacionais e a democratização do ensino a partir deles.

Published: May 2018

The study assesses the financial literacy level among tertiary students in Sub-Saharan Africa country, Ghana. The study uses primary data through self-administered questionnaires, and employs purposive sampling to select four hundred and eighty (480) students across tertiary institutions in Ghana for data analysis. The study reaffirms that on the average, students lack financial knowledge especially on insurance (mean = 40.54 percent). However, students portray the highest level of financial literacy in savings and borrowing (mean = 52.88 percent). Also, information technology positively influences 95 percent of student’s financial literacy. We recommend that tertiary institutions should inculcate educational program on financial literacy to broaden understanding of financial issues among students. Policy makers should redesign curriculum to include financial literacy courses especially for non-business students. Finally, financial seminars and talks should be focused on teaching relevant financial concepts and the youth should be educated and encouraged to utilize digital or technological platforms to enable them gain more knowledge in finance.

Theoretically, this research enriches the literature and gives a conclusion for previous researches about tax compliance in Indonesia, which results were varied. Practically, this research gives a clearer picture to the government about factors (tax socialization, tax knowledge, tax awareness, tax service quality, tax sanction, and tax audit) that could be improved to increase tax compliance.
Factors counteracting nurses' bullying in healthcare organizations: An applied study in King Abdul-Aziz University Hospital in Jeddah Province
Authors: Albishi Eman , Alsharqi Omar Z.
Published: May 2018

In a time of diminishing human resources in the field of healthcare, bullying among nursing staff is a challenge that has a negative effect on the individual nurse, work team, patient care, and consequently, on the entire healthcare organization. This study aims to investigate the presence of policy that addresses bullying, nurses’ knowledge and skills in dealing with bullying behaviour, and the role of nursing managers in counteracting bullying among nurses in the workplace. A quantitative descriptive study utilizing self-administered questionnaires was undertaken. The key results to come out from this study show that the presence of workplace code of ethics policies to address bullying behaviours and the role of nursing managers do not contribute to counteracting bullying among nurses in the selected hospital. However, nurses indicated the significance of knowledge and skills in counteracting bullying. The study conclusions contribute a number of findings of importance to the field of nursing management. The study disclosed significant correlations between the healthcare organization's bullying behaviours policy, managers’ roles, and nurses’ knowledge and skills in counteracting bullying. Nurses’ workplace bullying behaviours can be managed and eradicated by means of the collaboration of the three parties: nurse managers, policy, and nurses’ knowledge and skills. This study has considerable implications for nursing management in counteracting bullying among nurses. Managers have a fundamental role in counteracting bullying, for example by setting policy and conducting organization-wide surveys to study nurses’ job satisfaction, therefore, recommendations include mandatory peer reviews as part of an annual appraisal for each nurse, the initiation of a formal system to report behavioural issues among healthcare staff and the establishment of a committee to respond to, and deal with, behavioural issues among the organization’s staff.

Published: May 2018

This research examines the perception of customers towards sex appeal advertising. Effect of sex appeal advertising has to be measure in terms of ABC model of attitude, which are affective, behavioural and cognitive. Through the sex appeal advertising, cultural values, lifestyle and behaviours can be affected. Acceptance of nudity among different gender and religious had been investigated in Malaysia market. Research findings show that Chinese are more likely to accept mild sex-appeal advertising while Muslims could not accept it. Women perceive sex appeal more negatively than men, yet react quite positively towards sex appeal advertisements that is linked with the product itself. Other than that, high nudity levels in advertisements was not well received. Further analyses on the acceptance of sex appeal ads in Western countries compared to Asian countries where there’re major difference identified in terms of religion constraints and gender issue. Findings signify Malaysians are more conservative in terms of sex appeal advertising compared to the Westerns whereas females tend to be more sensitive towards sex appeal advertisements rather than males.
Forces Driving Purchasing Behaviour of Tourists Hotels Along Tourist-Agricultural Supply Chain in Zanzibar
Authors: Bengesi Kenneth M. K. , Abdalla Juma O.
Published: May 2018

This paper examined forces driving tourists’ hotels purchasing behaviour. The results revealed that the tourist hotels consider several factors before deciding to source vegetables and fruits from smallholder farmers. The most prominent factors for the tourist hotels to source vegetables and fruits were consistent quality, regular supply, compliance to legal practices, and hygiene conditions. Interestingly, proximity to the tourists’ hotels and competitive price of fruits and vegetables were not among important driving forces contributing to the choice of sourcing points. This suggests that the tourist hotels are willing to pay premium prices so long they are assured of quality and regular supply, comply to legal practices and observe hygiene conditions. With the fact that smallholder farmers lack access to appropriate market information, produce at subsistence level and lack logistic infrastructure this call for a change of mind-set among smallholder farmers and position strategically to take advantage of emerging markets.
Is Bottled Water Commodity in Saudi Arabia?
Authors: Alhidari Abdullah M. , Almeshal Soad Abdullah
Published: May 2018

The current study addresses an important question: is bottled water a commodity? How consumers in Saudi Arabia categorize bottled water? This study provides insights for marketers to understand the transition between commodity and brand. It also adds to the current literature on price fairness and brand trust by highlighting the impact of product design and e-WOM. Also, brand trust may not act as trigger to purchase intention, but it helps consumers to have higher value of the product. A total of 1079 completed and usable responses were from the total participants. The relationships between the constructs were tested using Structural Equation Modeling (SEM) with Maximum Likelihood (ML) estimate. Next, the theoretical and managerial implications to the results of the study are discussed. This study broadens our understanding of the product transformation from commodity to brand. Moreover, the result helps managers to differentiate the products and enhance brand trust for consumers to positively perceive the product price. The current study adds to the literature by addressing the consumers’ understanding of branding and commodity. Additionally, empirical evidence through this study contributes to the practitioners in the Saudi food market.
The Application of Text Mining Algorithms In Summarizing Trends in Anti-Epileptic Drug Research
Authors: Singh Shatrunjai P. , Karkare Swagata , Baswan Sudhir M. , Singh Vijendra P.
Published: May 2018

Content summarization is an important area of research in traditional data mining. The volume of studies published on anti-epileptic drugs (AED) has increased exponentially over the last two decades, making it an important area for the application of text mining based summarization algorithms. In the current study, we use text analytics algorithms to mine and summarize 10,000 PubMed abstracts related to anti-epileptic drugs published within the last 10 years. A Text Frequency – Inverse Document Frequency based filtering was applied to identify drugs with highest frequency of mentions within these abstracts. The US Food and Drug database was scrapped and linked to the results to quantify the most frequently mentioned modes of action and elucidate the pharmaceutical entities marketing these drugs. A sentiment analysis model was created to score the abstracts for sentiment positivity or negativity. Finally, a modified Latent Dirichlet Allocation topic model was generated to extract key topics associated with the most frequently mentioned AEDs. We found the top five most common drugs that appeared from the analysis were Gabapentin, Levetiracetam, Topiramate, Lamotrigine and Acetazolamide. We further listed the key topics associated with these drugs and the overall positive or negative sentiment associated with them. Results of this study provide accurate and data intensive insights on the progress of anti-epileptic drug research.
A Modified Characteristics-mixed Finite Element for Semiconductor Device of Heat Conduction and Numerical Analysis
Authors: Yuan Yirang
Published: May 2018

Numerical simulation of a three-dimensional semiconductor device of heat conduction is a fundamental problem in modern information science. The mathematical model is formulated by a nonlinear system of initial-boundary problem, which is interpreted by four partial differential equations: an elliptic equation for electrostatic potential, two convection-diffusion equations for electron concentration and hole concentration, a heat conduction equation for temperature. The electrostatic potential appears within the latter three equations, and the electric field strength controls the concentrations and the temperature. The electric field potential is solved by a mixed finite element method, and the electric field strength is obtained simultaneously. The first order of the accuracy is improved for the latter. The concentrations and temperature are computed by the characteristics-finite element method, where the characteristic approximation is adopted for the hyperbolic term and finite element method is use to treat the diffusion. The composite computational scheme can solve the convection-dominated diffusion equations well because it can cancel numerical dispersion and nonphysical oscillation. The temperature is computed by finite element method, and an interesting simulation tool is proposed for solving semiconductor device problem numerically. By using the technique of a priori estimates of differential equations, an optimal order error estimates is obtained. A theoretical work is shown for numerical simulation of information science, and the actual problem is solved well.

In a growing and competitive maritime world, it is necessary to improve the operational quality of port terminals in order to satisfy customers. This observation was made at the container terminal in Abidjan. In this paper, the goal is to minimize the overall duration of the transfer operations of the containers on railcars to neighboring countries. Considering the resources of the container terminal in Abidjan, we propose a non-linear programming model of the problem, we solved it using the AMPL language (Mathematical Programming Language) and we have used the KNITRO 10:2 solver for the solution.
A Novel Approach to Find Pseudo–peripheral Vertices for Snay’s Heuristic
Authors: Gonzaga de Oliveira Sanderson , Bernardes Júnior A. B.
Published: May 2018

The solution of linear systems represented by Ax = b is fundamental in many numerical simulations in science and engineering. Reducing the profile of A can reduce the storage requirements and time processing costs of solving such linear systems. In this work, we propose a generalized algorithm for finding pseudo–peripheral vertices for Snay’s heuristic. In experiment performed on 36 instances contained in the Harwell-Boeing and SuiteSparse matrix collections, it has been found that the number of pseudo– peripheral vertices selected in Snay’s heuristic may be suitable for small instances, but it is insufficient to obtain reasonable results in instances that are not small. This paper recommends to select up to 26% (0.3%) of pseudo–peripheral vertices in relation to the instance size when applied to instances smaller than 3,000 (larger than 20,000) vertices.

The winter of 2016 was cold, snowy, summer is hot and rainy, compared to 2011-2015 average in Battsengel soum. In 2017 the winter is warmer, summer is less hot and precipitation than in 2016. In territory of 6 bags of Battsengel soum observed 23 pasture types. There are 13-44 species per 100 m2 of pasture, including 2-8 species indicating pasture degradation. In the pasture area of Batsengel soum were recorded 87 species of plants belonging to 24 families and 61 types, including 15 species of indicating pasture degradation. In Batsengel soum, in 2016 the moisture was abundant and the vegetation coverage of the pasture was 56.55%, including the grasses was 23.18% and the bare land - 26.54%, and in hot and dry 2017 the vegetation cover was 38.01% which has level of grasses dropped to 11.86% and bare land increased to 41.44%. In 2016 the Battsengel soum had 324746 heads of livestock (623713.3 sheep heads) and in 2017 counted 372546 heads of livestock (713494.9 sheepheads) while the number of livestock increased in 13%. By increasing the number of livestock and climate condition the pasture carrying capacity was 1.7 times in 2016 and 3.5 times in 2017 over.

Studies of population genetic diversity is important research field in conservation and restoration of animal breeds and genetic resources. The control region of mitochondrial DNA is widely used for population and evolutionary studies because of its‘ maternal inheritance and high level of sequence variation as well as its‘ much less recombination rate. To determine genetic diversity and maternal inheritance, we collected 10 blood samples of Tes horses from Zavkhan, Mongolia. In this study, 8 haplotypes and 44 polymorphic sites were detected. Haplotype diversity was 0.9333 and nucleotide diversity was 0.0224. 4 haplogroups (A, C, F, I) were identified among 8 haplotypes.

The state protected areas (PAs) lack with financial resource, which weakens the PA management including lack of human resource and their skill development, transparent cooperations, and of equipments and vehicles for ecosystem conservation and rehabilitation activities of the PAs. Thus, research on analysing the economic value of the PAs is vital important for the decision makers and policy planners, because they have lack of understanding of benefits of investing to the PAs. In 2013, United Nations Development Programme published a book that reflects the approach of “Targeted Scenario Analysis”, which is used in our study. The Khangain Nuruu National Park (KNPA) locates in 11 soums of three provinces, namely Arkhangai, Bayankhongor and Uvurkhangai, and we analyzed economic value of the KNPA for six economic sectors (livestock husbandry, crop farming, forestry, tourism, mining and industry), and two non-economic but consumption based sectors (carbon sequestration from larch trees, and drinkable water). The economic value or the contribution to the economy of Mongolia from KNPA was about MNT 165.4 billion in 2014, and it summed up to MNT 1 trillion between 2002 and 2014. Livestock husbandry, mining and tourism sectors benefitted about two third of this value. In case of “Business As Usual-BAU” scenario takes, continuesly, in place the total economic loss would reach to MNT 1.4 trillion between 2015 and 2040, compared to “Investing in Natural Capital-INC” scenario. Hence, implementing INC in the KNPA management would save this loss. We recommend to increase the financial resources for the KNPA management, therefore the economic sectors will not diminish due to lack of ecosystem services of the PA, which would then develop the sectors in the long run sustainably.
