Published: July 2019

In the present research biocomposites based on extracts of collagen and keratin recovered from the leather industry by-products were made and the specific properties for applications in agriculture and industry were studied. To this aim, collagen and keratin have been extracted from bovine leather and sheep wool by-products and have been added and crosslinked with recognized compounds for reduced environmental impact (glycerol, vegetable tanning extract, essential oils with fungicidal properties and insecticides). The biocomposite properties were evaluated on the basis of complex analytical investigations on chemical structure, texture, contact angle, mechanical resistance, water vapor permeability and water absorption, biodegradation, germination and plant biomass growth. The biocomposites have demonstrated pelliculogenic properties and nitrogen controlled release to stimulate germination and nutrition of rape seedlings, which promotes them for agricultural applications, but also other surface properties have been identified, for industrial applications, for example in leather finishing for special destinations. Addition of odorous principles with controlled release recommends this type of biocomposites for environmentally friendly products, maintenance of cleaning, etc.
The influence of surface fire on radial and height growth of Pinus sylvestris L. in forest-steppe in Ukraine
Authors: Koval Iryna , Sydorenko Serhiy
Published: July 2019

The article presents the results of the research on the peculiarity of response of Pinus sylvestris L. growth in height and diameter in young pine forest stand of the Left-Bank forest-steppe of Ukraine under the influence of surface fire that happened in May 2011. Forestry taxation, comparative ecology, standard dendrochronological methods were used. Response of trees was different for the height growth and the radial increment in the year of fire (2011). The radial growth got depressed in the year of fire; at the same time, the height of trees showed positive trend of growth against the background of favourable weather conditions. The growth in height was more ductile and completed its recovery to a particular level in 2014, unlike the radial growth, which recovered only in 2016. The relationships between radial growth on one side and stand sanitary state and height of bark char on the other were approximated by quadratic and cubic regression equations. Dynamics of pine growth depends on climatic factors also. Percentage of the late wood should be used to assess the condition of stands after fire. Research of post-pyrogenic development of forest ecosystems will allow more effective planning of forest management measures, and also allow the adjustment of the monitoring duration for pine forest stands damaged by fires.

Investigating the Effect of Aeration on the Flow Characteristics Around Under Pressure Tunnel Aerator Using Openfoam Open Source Software
Authors: Ebrahimnezhadian H. , Manafpour M.
Published: July 2019

The flow around the ramp embedded in a pressurized tunnel is divided into the various zones immediately downstream of the ramp, including the cavity and the main zone of flow above the shear layer. The aeration coefficient of the flow from the lower surface (inside the cavity)(βlower) is a function of non-dimensional numbers which aerator geometry parameters such as cavity length to ramp height Lc/tr is considered as one of the most important parameters. Therefore, in the present study, OpenFOAM software and RNG k-ε turbulence model were used to simulate the flow to study the aeration effect on flow characteristics, so the range of aeration coefficient as 0%<β<10% for four ramps with different tr/d ratios is Applied, then by increasing the aeration coefficient in the range of 0%<β<16%, The dependency range of relative Cavity length Lc/tr to (β) was evaluated. In order to verify performance of the numerical model, experimental results of Manafpour test were used. The results of the research indicate that in the aeration of flow with aerator ramp, the height of ramp has more influence relative to ramp angle. Moreover the main Effectiveness of the aeration coefficient on the cavity length was limited to air percent less than 10%.

Authors: Hakimian Saeed , Mosallanezhad Mansour
Published: July 2019

In recent years, the implementations of Micropiles have been increased extensively in large project constructions due to the unique advantages of this method comparing to concrete piles. The results of numerical analysis and centrifuge tests show that the efficiency and importance of micropiles can be considered as an effective solution. This research is designed to compare the newly designed system of microbulb with micropile applying a numerical modeling with finite element software Plaxis 3D foundation v1.6. We also used the FHWA code for a comparative study between micropiles and microbulbs. Then the effective factors were analyzed in order to decide which method is better between these two methods of micropile and microbulb. The results showed that the new microbulb system is an appropriate solution for improvement of mechanical properties of the soil, increase of bearing capacity and settlement decrease.

Published: July 2019

Foam concrete or light concrete has become increasingly recognizable in commercial and construction field. Foam concrete is not just light in its weight but also light in cost, as there is no coarse aggregate needed in its production. Application of foam concrete is limited due to the fact that it is not as strong as conventional concrete in terms of strength and rigidness. Therefore, this study is to investigate the potential of foam concrete incorporating with rubber powder of waste tire and admixture as an additive material to improve its strength and workability. Thus, the use of rubber powder in this study could enhance the strength by filling the voids in foam concrete. The amount of rubber powder added as additive in foam concrete is 0%, 5%, 10%, 15% and 20% respectively. The amount of plasticizers used is limited to less than 0.4% to the weight of cement. The mix design was set to achieve density of 1800kg/m3. The workability of foam concrete is decreasing as the percentage of rubber power was increasing. The foam concrete containing 5%of rubber powder has highest compressive strength with value of 20.6 MPa for 7 days water curing and 22.3 MPa for 28 days water curing. Significantly showing an increase of 1.7 MPa. The highest value of tensile strength for both air curing 7 and 28 days are 1.86 MPa and 1.97 MPa also held by 3% of rubber powder mix. As a conclusion the optimum rubber powder content to be used in foam concrete is 5% that gives the highest results in terms of workability and strength.

Published: July 2019

This research aims to define the degree of enjoyment in regions of Tabriz metropolis through innovative city indicators with an emphasis on the social and cultural indicators. In terms of practical purposes, the present study is of applied research type, and in terms of the nature of methodology, it is a comparative research. In this research, Shannon entropy method for weighing criteria is used to determine the weight of each of the indices under study, and a TOPSIS technique is applied in order to rank the regions of Tabriz metropolis to create the innovative city. Emphasizing on the social and cultural indicators, the findings of the research show that region 8 tops the ranking list and region 10 is ranked the last in terms of enjoyment through innovative city indicators. The result of this research indicates that the social and cultural indicators are not distributed equitably to fit well into an innovative city concept, and there is a focus on spatial distribution of indicators. Moreover, the results of this research indicate the incompatibility of the distribution of social and cultural indicators with the distribution of population across the city. Therefore, since innovation is the key to the development and expansion of cities as well as the equitable and rational distribution of services and facilities necessary for development and progress, the fair distribution of social and cultural indicators is essential for the realization of an innovative city.

Authors: Mahagamage M.G.Y.L. , Manage Pathmalal M.
Published: July 2019

Typhoid or enteric fever is a worldwide infection caused by the bacterium Salmonella enterica. In Sri Lanka, 12,823 Salmonella positive cases were recorded and 133 cases were recorded from Anuradhapura district during 2005 to 2014. Therefore, the study was carried out to identify the microbiological and chemical contamination status of forty-four water sources in Anuradhapura area during October 2016. The study was focused to determine total coliform, faecal coliform, Salmonella spp. and Shigella spp. contamination along with some physico-chemical parameters of both ground and surface water. Sampling, transportation, and analysis were performed following standard protocols. Results of the study revealed that almost all sampling locations were contaminated with both total and E. coli bacteria and the values were not within the World Health Organization and Sri Lanka Standards drinking water quality standards. Around 32% of sampling locations were positive for Salmonella spp. and among them, 2 spring sampling locations are being highly used to extract water for drinking. However, Shigella spp. was not recorded during the study period. Majority of the sampling points were not within the Sri Lanka drinking water standards for COD and 25% sampling locations were recorded greater than 750 μS∙cm−1 conductivity. Also, 55% of locations recorded very hard water where the highest values were recorded in Padaviya. The tested other water quality parameters: NO2-N, NH3-N, and total phosphate (TP) concentrations were found within the Sri Lanka drinking water standards. PCA analysis revealed that sampling locations were grouped into three groups such as; well water, tank water and springs.

Authors: Benmarce Kaddour , Khanchoul Kamel
Published: July 2019

Water quality is an important criterion for evaluating the suitability of water for drinking and domestic purpose. The main objective of this study was to investigate the physicochemical characterization of groundwater for drinking water consumption. Ten captured sources were selected from three aquifers including the Guelma Mio-Plio-Quaternary alluvial basin; the Senonian Heliopolis Neritic limestone aquifer, and the Eocene limestones of Ras El Agba-Sellaoua aquifer. The analyses concerned the periods of high water in May 2017 and low water in August 2017. Twelve parameters were determined for the water samples: pH, T (°C), EC, Ca2+, Mg2+, Na+, K+, Cl−, HCO3−, SO42−, NO3−, TH (hydrotimetric degree), TAT (total alkalinity titration). The interpretation of the various analytical results allowed the determination of the chemical facies and the classification of the groundwater aquifers as follows: (i) in the alluvial layer, the gypsiferous marl substratum and the clays of the three terraces (high, medium and low) have given the water a chlorinated calcium chemical facies in the east part of the study area and travertines feeding partly alluvial layer, and have given a bicarbonated calcium water facies in the west, (ii) in the Senonian of Heliopolis limestone and Eocene carbonate formations of Ras El Agba-Sellaoua, the chemical facies are calcium bicarbonate. Water isotopes (δ18O and δD) helped to determine the origin of groundwater. Overall, the groundwater in the area is hard and has significant to excessive mineralization. It is progressively degraded in the direction of flow, especially in the Guelma alluvial aquifer.

Authors: Pla-Julián Isabel , Díez Jose-Luis
Published: July 2019

Despite the growing interest in the subject, the gender perceptions in the context of university studies have not been sufficiently studied so far. In this contribution, what is being proposed is a practical approach in the Spanish university system assessing the progress regarding the perception of equality among students receiving training on gender perspective in the framework of an Equality Plan. For this purpose, a case study was designed by assessing the progress as regards equality perceptions in the student body of the Universidad de Valencia Estudio General (UVEG). 338 students in grades filled out questionnaires on gender both before (225) and after (113) receiving a course in gender training. Results show Equality Plans with gender training significantly improves gender perception in university students. Academic institutions can play an essential role in ensuring developing Equality Plans with initiatives in education concerning gender equality.

Published: July 2019

The study focuses on repositioning the manufacturing sub-sector in order to revive Nigeria from the problem of “growthelessness”. The expository study examined the situation of the Nigerian economy and overview of the industrial policies employed to encourage development since after independence. Many challenges such as lack of indigenous technology, excessive reliance on foreign raw materials and manpower, inconsistence regarding policies and programmes, lack of linkages of production with domestic inputs among others were articulated to be responsible for the inability of the country to establish a reliable manufacturing sub-sector that is capable of harnessing idle resources, reduce unemployment and develop the economy. The study also examined an overview of industrial policies employed by South Korea which gave the country its success story. Lessons considered to play significant role to change Nigerian manufacturing sub-sector were drawn there from, among which include: reviving the economic environment with infrastructure and public service system so as to make the country industrial production compliance; consistent, persistent and perseverance on the part of resource controllers in spite of all odds toward goal attainment, adoption of appropriate indigenous technology, monitoring, evaluation and restrategising to improve the sector. This study has shown that Nigerian situation is capable of changing for better if what worked in South Korea manufacturing sub-sector is applied in Nigeria.

CFD Analysis of the Fluid Particles Distribution by Means of Aviation Technique
Authors: Seredyn Tomasz , Dziubiński Adam , Jaśkowski Piotr
Published: July 2019

The article describes a computational study, using CFD models, of droplet spray dispersal in the wake of a ‘Turbo Kruk’ airplane up to 500 m downstream. The CFD Reynolds-averaged Navier-Stokes (RANS) models use a Lagrangian (droplet phase) and Eulerian (fluid phase) procedure to predict the droplet trajectories trough the turbulent aircraft wake. The methods described in the work have the potential to improve current models for aerial spraying and will help in the development of new spraying procedures. In this study, the CFD models are used to describe the phenomenon of sprays released from atomizers mounted on the plane. A parametric study of the aircraft model examines the effects of crosswind on the aircraft’s vortex structures and the resulting droplet trajectories. The study shows, that such influence is underestimated in the current models. A comparison of the present results to AGDISP predictions is provided.

This paper is a review of testing methods dedicated for sandwich type composite structures with honeycomb core. First, information about the composition of sandwich materials structures, their properties, types of core materials and applications in the industry is presented. Mechanical properties were compared in the case of different types of the core material. Later, tests methods needed to describe properties of those materials and normalization organizations which create them were mentioned. The testing methods were divided into two groups: mechanical and physicochemical tests. Mechanical properties are: compressive strength (two types of test), edge compressive strength, shear strength (in two directions) and tension strength (two types of test). Physicochemical properties are: material density, water migration, water absorption and thermal conductivity. Testing methods were described according to American Society for Testing and Materials (ASTM) standards. This article is based on professional literature and the author’s experience.

Let It Go: Multicultural Society inLosby Tom Naegels
Authors: Pareit Timothy
Published: July 2019

Although scholars in the Netherlands have already attempted to integrate literary theories on migration with the specific Dutch context, none such attempts have so far been made for Flemish literature. The current paper therefore scrutinises the novelLosby Tom Naegels, an (autobiographical) account of the riots in Borgerhout (Antwerp) after the murder on Islam teacher Mohamed Achrak in 2002. As the author also covered these events as a journalist, the analysis investigates the manner in which this topical matter is intertwined with the more personal story about the struggle conducted by Naegels’s grandfather for euthanasia. The paper leans on Jérôme Meizoz’s posture theory, which differentiates the author figure from the biographical person and the narrator. In addition, the novel is situated within the contemporary literary return towards realism and Flemish literature’s negotiation of Flemish identity. By focussing on these three elements – the theme of migration, realism and Flemish identity – the paper attempts to contribute to the development of a literary theory on migration in Flanders.

Authors: Jackson Alexander , Young Michael , Howes Satoris , Knight Patrick , Reichin Sydney
Published: July 2019

In this research, two studies were conducted to examine factors influencing reliance on a decision aid in personnel selection. Specifically, this study examined the effect of feedback, validity of selection predictors, and presence of a decision aid on the use of the aid in personnel selection. The results demonstrate that when people are provided with the decision aid, their predictions were significantly more similar to the predictions made by the aid than people who were not provided with the aid. This suggests that when people are provided with an aid, they will use it to some degree. This research also shows that when provided with a decision aid with high cue validity, people will increase their reliance on the decision aid over multiple decisions.

Authors: Risavy Stephen , Fisher Peter , Robie Chet , Konig Cornelius
Published: July 2019

The purpose of this paper is to provide new data regarding the current staffing practices being used by organizations in Canada and the United States (US) as well as a comparison with existing data from Germany (Diekmann & König, 2015). Data regarding the beliefs of human resource (HR) practitioners in terms of using personality tests in personnel selection is also provided. A geographically representative sample of 453 HR practitioners across Canada and the US were surveyed. Although general mental ability testing has previously been found to be highly valid and cost effective, this selection tool was among the least commonly used in all three countries. Personality tests were also rarely used (especially in Canada and the US) and research–practice gaps still appear to be an issue (e.g., HR practitioners’ preference for personality types as opposed to traits).

AdBippyPhos Promotes Pd-Catalyzed C–N Coupling Between Weakly Nucleophilic Sulfonamides and Heteroaryl Halides
Authors: Becica Joseph , Hruszkewycz Damian , Steves Janelle , Elward Jennifer , Leitch David , Dobereiner Graham
Published: July 2019

Sulfonamides are poor nucleophiles in Pd C-N coupling catalysis, hindering synthesis of densely-functionalized N,N-diaryl sulfonamide motifs relevant to medicinal chemistry. Through targeted high-throughput experimentation (HTE), we have identified the Pd/AdBippyPhos catalyst system as an effective and general method to construct this difficult to access moiety. In particular, AdBippyPhos is critical for the installation of heteroaromatic groups. Computational steric parameterization of the investigated ligands reveals the potential importance of remote steric demand, where a large cone angle combined with an accessible Pd center is correlated to successful catalysts for C-N coupling reactions.

Adiscussão se focaliza nas relações entre os Ashaninka da aldeia Apiwtxa (Brasil) e osAshaninka da Comunidad Nativa de Sawawo (Peru), ambas situadas no rio Amônia,afluente do Juruá. Procura-se mostrar que, apesar de pertencerem a um mesmo povo eda existência de fortes laços de parentesco entre as duas comunidades, as relações entreApiwtxa e Sawawo tornaram-se cada vez mais tensas nos últimos anos.Os conflitos latentes e a dinâmica identitária dos Ashaninka está intimamenterelacionada com a participação diferenciada dessas duas comunidades nos processos deterritorialização e de desenvolvimento que afetam profundamente a geopolítica dessaregião de fronteira. Embates em torno de modelos de desenvolvimento dividiramprogressivamente os Ashaninka brasileiros e peruanos. Enquanto os Ashaninka daaldeia Apiwtxa se tornavam os principais porta-vozes de projetos de “desenvolvimentosustentável” para a região do Alto Juruá, as lideranças da comunidade de Sawawo seenvolviam com as políticas desenvolvimentistas predatórias do governo peruanocaracterizadas, sobretudo, pela exploração descontrolada de madeireira, invadindo, emalgumas ocasiões, a Terra Indígena Kampa do Rio Amônia e o território brasileiro

Os newen nos processos políticos de produção e socialização de conhecimentos-ontologias
Authors: Ramos Ana Margarita , Sabatella María Emilia
Published: July 2019

No marco da proposta cosmopolítica, centrada nas articulações possíveis entre mundos ou ontologias divergentes, este trabalho propõe-se a pensar o parlamento ou Futa Trawün mapuche-tehuelche como uma instância de produção, transmissão e socialização (ngulantuwün) de conhecimentos-ontologias. No ano de 2002, as comunidades e organizações indígenas da província de Chubut (Patagônia argentina) decidem retomar essa prática ancestral, em face do avanço da propriedade privada e da mineração sobre seus territórios. O interesse nesses encontros políticos reside, por um lado, no fato de sua própria existência ter sido definida a partir de uma epistemologia entendida como mapuche-tehuelche, e, por outro, no modo como o conhecimento-ontologia é ali reatualizado como uma prática política. Portanto, o Futa Trawün é um interessante ponto de partida para levar a cabo uma reflexão acerca da relação entre os processos políticos e outras formas epistêmicas de entender a política.

Published: July 2019

A floresta se encontra no coração da paisagem cultural dos Anichinabés de Kitcisakik, no Canadá. Da mesma forma que para numerosas nações autóctones deste país, o território ancestral desta comunidade algonquina da Província do Quebec tem sido objeto de contínuas intervenções florestais desde o final do século xix. Para enfrentar esta problemática, o povo de Kitcisakik escolheu se envolver em um processo de pesquisa colaborativa, apoiado por um quadro de referência em educação ambiental. Esta iniciativa permitiu iniciar um diálogo intercultural tendo como objetivo definir os fundamentos de uma silvicultura mais bem adaptada ao contexto indígena. A pesquisa revelou o caráter identitário da floresta (nopimik) para os Anichinabés e a dimensão preocupante da silvicultura. A partir do sistema de representação anichinabé, elaboramos um quadro de cinco princípios (cultural, ético, educativo, ecológico e econômico) e de 22 critérios de silvicultura indígena. Esta proposta é analisada no contexto das mudanças normativas e legislativas implementadas no Quebec pela nova Lei sobre o ordenamento sustentável do território florestal e o reforço dos critérios de certificação florestal do Forest Stewardship Council (FSC).

Authors: Pabon Ana Patricia , Aguirre Román Javier Orlando , Giraldo Torres Juliana
Published: July 2019

El presente texto explora cuatro enfoques teóricos de la democracia contemporánea, así como las críticas que se formulan desde los autores más recientes a cada uno de estos, en especial desde el modelo agonístico. Estos desarrollos teóricos se pueden tomar como referentes para analizar la tensión que en el sistema político y jurídico colombiano se vive alrededor de las consultas populares frente a la adjudicación de títulos mineros. Para abordar este escenario se tendrá como referente el caso del municipio de Cajamarca. Este artículo es producto de un análisis teórico – deductivo en el que se analizan fuentes documentales a partir de la hermenéutica crítica.  El principal resultado del análisis del caso de Cajamarca es comprender la tensión que plantean los enfoques de la democracia agonística y las críticas a los modelos liberales de democracia formal.

Published: July 2019

This
study aims to determine and evaluate the learning barriers of high school
students in Turkey. These barriers are examined from various emotional and
motivational dimensions, such as self-efficacy, self-regulation, deficiency of
professional/parental/sibling support and consultancy, learning environment,
fear of failure, rejection, criticism and judgment and embarrassment. These
dimensions in learning barriers influence all kinds of measurements to be
carried on about students. Therefore, describing and revealing them may help
handle the measurement outcomes gathered from students in different ways. The
study employed a descriptive research methodology to collect data from all
regions of Turkey. In this study, six scales were administered to the
participants, who are 2175 high school students from the ninth, tenth and
eleventh grades attending high schools. The results of the study suggest that
students have some difficulty in planning how to study, which is a
self-regulative skill. The participants’ views mostly show that teacher support
can make a strong learning barrier. Parental support is also another learning
barrier.  Furthermore, it was found out
that the learning environment in classrooms did not motivate students to learn.

Despertando para a cultura material: representações midiáticas do café e do chocolate na publicidade
Authors: Pereira Cláudia da Silva
Published: July 2019

O objetivo do artigo é discutir, à luz das teorias

antropológicas, especialmente daquelas dedicadas

à análise do consumo e da cultura material

como fenômenos sociais, as representações de

determinadas “coisas” em suas relações com valores

e práticas da cultura ocidental contemporânea –

aqui, o café e o chocolate, em suas representações

midiáticas na Publicidade. Para tanto, este trabalho

sustenta-se em autores como Marshall Sahlins

(2003) e Daniel Miller (1987), entre outros. A partir

do que foi aqui analisado, reforçam-se as premissas

de que “coisas” e “pessoas” constituem partes de

uma mesma ontologia cultural, ligadas por lógicas

que estão para além da razão prática.
Desigualdades estruturais de gênero no trabalho jornalístico: o perfil das jornalistas brasileiras
Authors: Pontes Felipe Simão
Published: July 2019

A Pesquisa Perfil do Jornalista Brasileiro, realizada

pelo Programa de Pós-Graduação em Sociologia

Política da Universidade Federal de Santa Catarina

(UFSC), apresentou pela primeira vez dados

demográficos, políticos e de atuação profissional do

jornalismo no Brasil. Sob a metodologia da online

survey, foram entrevistados 2731 jornalistas de

setembro a novembro de 2012, de todos os estados,

respeitando a proporcionalidade por região, com 2%

de margem de erro e 95% de nível de confiança. Um

dos principais resultados da pesquisa aponta que a

cada três jornalistas brasileiros, duas são mulheres.

Utilizando a base de dados da pesquisa Perfil do

Jornalista, este artigo analisa comparativamente

as informações sobre homens e mulheres que

trabalhavam na mídia em 2012, com ênfase nas

variáveis: renda, cargos ocupados e acesso a

benefícios no emprego. Os resultados revelaram que

as mulheres ganham menos que os homens em todas

as faixas etárias e funções. Ainda têm menos acesso

a benefícios e não gozam da mesma recompensa no

mesmo cargo e/ou empresa que seus colegas homens,

o que demonstra desigualdades estruturais de gênero

presentes no trabalho jornalístico brasileiro.
Telejornalismo “participativo”: pressão das audiências ou fragilidade das instituições
Authors: Pereira Junior Alfredo Eurico Vizeu , Alves Kellyanne Carvalho
Published: July 2019

A televisão no Brasil ganha mais força a partir da

década de 70. A televisão evoluiu com os anos até

chegar nos dias de hoje, quando a audiência tem

um papel de destaque. O trabalho propõe discutir a

participação da audiência ativa nos telejornais a partir

de duas linhas de investigação: a agenda da pressão

social e a fragilidade das instituições. Tem-se como

exemplo de experiências participativas, no telejornal,

o quadro “Calendário”, que surge no NETV da Globo

Nordeste e se espalha para outras afiliadas da Rede

Globo de Televisão pelo país. Busca-se apontar pistas

para compreender melhor a relação da audiência ativa

com o telejornalismo, que é eleito por ela como um

mediador social frente aos problemas da comunidade.

“Vamos tirar a educação do vermelho”: o Escola Sem Partido nas redes digitais
Authors: Romancini Richard
Published: July 2019

O artigo apresenta um estudo de caso do movimento Escola Sem Partido (ESP), que combina análises da cobertura noticiosa e da atuação de indivíduos e instituições que utilizam a rede social Twitter (a partir da hashtag #escolasempartido). O pano de fundo teórico envolve a questão da midiatização da política e o ativismo digital contemporâneo. Em termos de resultados, é possível destacar: a cobertura dos meios informativos é geralmente neutra ou desfavorável ao ESP; a discussão no Twitter é realizada majoritariamente pelos apoiadores da causa, com uso significativo de meios de comunicação de baixa qualidade; muitos tweets utilizam técnicas da mídia participativa.
