EFFECTS OF NITROGEN FERTlLlSER ON PRODUCTION OF MILK SOLIDS FROM GRAZED PASTURE
Authors: Bryant A.M. , Macdonald K.A. , Clayton D.G.
Published: July 2020

In each of two years, eight 6.48 ha farmlets were used to assess effects of urea applications on dairy production. In the first year, 86 kg N/ha were applied in 2-3 dressings during May-August. Effects on annual milkfat and pasture production were not significant. In the second year 3-4 applications totalling 137 kg N/ha in April to September significantly increased annual milkfat and pasture production. Response in milkfat production per hectare to urea application averaged 0.22 (range - 0.16 to 0.45) and 0.25 (range - 0.1 I to 0.39) kgfat/ kgN in the first and second years respectively. These responses were not economic at present-day prices.
NITROGEN BALANCE IN AN INTENSIVELY UTILISED DAIRYFARM SYSTEM
Authors: Field T.R.O. , Ball P.Roger
Published: July 2020

4 N balance representative of intensive dairyfarming is presented, based on a dynamic model integrating information on N flows for this system. Losses of about 50% of N ingested by animals lead to a negative N balance with predicted annual losses of 40 kg N/ha. Addition of 100 kg fertiliser N is predicted to reduce the N deficit by 13 kg/ ha, with increased leaching and lower clover fixation reducing the effectiveness of applied N. Increasing the level of utilisation from 70 to 75% of herbage produced, by increasing stocking rate, is predicted to increase annual losses to about 60 kg/ ha. Additional losses from excreta and reduced cycling of dead plant material contribute to the increased deficit. The implication of losses of this order to farm productivity are discussed.
THE PLACE OF TARANAKI IN DSIR ENERGY STUDIES
Authors: Kear D.
Published: July 2020

New Zealand is an energy-rich country. DSIR research and exploration are described in defining our national resources of hydro-electricity, coal, geothermal energy and petroleum (natural gas and oil), all of which are know known to be considerably larger than was thought only a few decades ago. In Taranaki there is very limited hydro-electrical potential; only modest quantities of coal in difficult locations and no geothermal potential despite the presence of the dormant volcano Mt Egmont. However, the province does contain New Zealand's best production and future prospects for natural gas and oil. DSIR investigations into alternative developments for synthetic liquid fuels is also discussed.
HERBAGE PRODUCTION BY RYEGRASS, TALL FESCUE AND PHALARIS AT DIFFERENT STOCKING RATES
Authors: Harris W.
Published: July 2020

Swards of 'Grasslands' Nui ryegrass, Roa tall fescue and Maru phalaris were grared according to feed budgets to consume the estimated annual requirement of 15, 20 and 25 breeding ewes ha-r. The effects of these 9 grazing systems on seasonal changes of, and interrelationships between standing herbage mass (V), achieved herbage consumption(C) and net herbage accumulation rate(G) are examined. The relationship of G to V varied between seasons, but for a full year G decreased by 3 kg DM ha-r day-r for each 1000 kg DM ha-r Increase of V. Estimated consumption requirements were exceeded at 15 ewes ha-r, were about adequate at 20ewes ha-r, but were deficient at 25 ewes ha-r. 4t 25 ewes ha-r ryegrass provided 28% more consumed herbage than phalaris. Indications are that at stocking rates at which G is near maximum and differences between grass species important, intake, and hence per animal performance, may be restricted.
PLACE OF OVERSOWN LUCERNE IN DRY HILL COUNTRY FARMING SYSTEMS
Authors: Musgrave D.J.
Published: July 2020

Four years data from a steepland site near Omarama, North Otago (500 mm rainfall), shows that on average oversown lucerne produced 5.3 t/ha/annum, with 3.3 t/ha of this being produced between mid August and late November. The translation of this small-plot yield to expected production under normal grazing is discussed. In deriving the expected production, corrections are made for the long term production from nearby dryland lucerne stands, the effects of varying terrain within hill blocks and the effects of grazing management on utilisation. Recent research results and farmer practice both indicate that extensive areas of lucerne can be managed with simple systems that do not necessitate more intensive subdivision than for pasture. The expected production under grazing is used in a linear programme model of a semi-arid zone farm system, which includes a wide range of options. Examples investigated with the model included 'warm' and 'cold' properties, varying levels of development and allowing some irrigation. The likely costs of establishing lucerne are some 70% greater than for a clover-based pasture. However the model shows that the pattern and quantity of grazing provided by lucerne on low-sunny country makes it a profitable part of a development programme that balances year-round feed supplies, particularly on colder properties. Keywords: Medicago sativa, rangeland, semi-arid, oversowing, grazing management, profitability, model.
ESTABLISHMENT OF HILL COUNTRY WHITE CLOVER SELECTIONS FROM OVERSOWING
Authors: Charlton J.F.L. , Giddens N.G.
Published: July 2020

The establishment characteristics of three hill country white clover selections were compared with 'Grasslands Huia' and Kent white clover after oversowing in spring and autumn on a low fertility, summerdrv hill country site near Palmerston North. The hill country selections gave 15-16% establishment of sown seed in spring. whereas in autumn two of the hill country selections established much higher seedling numbers than other clovers, one-third surviving at 6 weeks. Less than 5% of Huia seed established in autumn. Less than one-quarter of spring-sown seedlings survived dry summer conditions. Plant survival at one year after autumn oversowing was markedlv better and at this stage, two of the hill country selections had developed 6 times the stolon density of Huia and they were giving at least 3 times the herbage content in the pasture.

WHY OVERDRILLING RED CLOVER IN MANAWATU LOWLAND FAILED
Authors: Campbell B.D. , Cosgrove G.P. , Harris W.
Published: July 2020

Experiments examining methods of establishing Pawera red clover in Manawatu found that overdrilling failed to produce the wider spread of seasonal production and higher yield obtained when Pawera iscombined with ryegrassesusingconventional cultivation. In discussing responses obtained production is separated into two components - plant number and plant size. These components collectively determine the contribution made by Pawera. Results are presented to show the potential for using machinen/, technique and management options to improve the performance of overdrilled Pawera. The feasibility of these is discussed. Deficiencies in present knowledge are also emphasised. Keywords: Red clover, overdrilling, plant number, plant size

WHAT IS THE MAKE-UP OF A DRYLAND PASTURE?
Authors: Vartha E.W. , Hoglund J.H.
Published: July 2020

Summer grazing managements, spelling, set-stocking, fast or slow rotations and topping or no topping, did not influence herbage growth in autumn of Nui ryegrass pasture. The cause of pasture deterioration on dryland, previously suggested to be through summer overgrazing, now seems more likely to be an effect of autumn overgrazing, particularly if pastures have been attacked by Argentine stem weevil and drought is continuing from summer. Low nitrogen fertility through often low fixation of nitrogen by clover, uncertainty of response of pasture to nitrogen fertiliser in cool season, and the effects from overgrazing, cause an extreme limitation in autumn-winter feed supply for stock in drought years. Feeding of silage in summer-autumn is advocated as a positive approach to this situation. On sunny aspects of dry hill country, buildup of dead herbage through summer considerably reduces the quality of the subsequent cool season growth of grass in the herbage mass. Several attempts to establish oversown grasses for improved cool season yield have not been successful. Dry hill grassland thus provides a considerable challenge to effect much improvement beyond manipulating the quality of the existing vegetation by grazing management.

GRASS GRUB: COPING WITHOUT CHEMICAL CONTROL
Authors: French R.A. , Pearson J.F. , Vartha E.W. , Fraser T.J.
Published: July 2020

A field experiment lasting four years in the Carew district of mid-Canterbury, investigated the recovery of ryegrass pasture severely damaged by grass grub. Overdrilling with grasses was unsuccessful, in this instance being done too late in spring. The time course of recovery of damaged pasture without and with insecticide was compared against resowing after a barley crop with either Ruanui or Nui ryegrasses, Maru phalaris or Matua prairie grass. Recovery of ground cover from damaged pasture was through infill by weed grasses and white clover. Insecticide maintained more ryegrass herbage. Yields from renovated pasture in autumn were considerably lower than those from renewed pasture. However, the renewed pasture was again generally severely damaged by grass grub within two years. The exception was Maru phalaris which was tolerant of grass grub. Yield of herbage from Maru in autumn was however lower than from more severelydamaged Matua pasture. Successful experience elsewhere with overdrilling Nui ryegrass into grass grubdamaged pasture is mentioned when such pasture was heavily stocked under wet soil conditions in early winter, then overdrilled in late winter.

Situated in the Ure Valley 61 km from Blenheim, 'Peggioh' was purchased by the author in 1976 and farmed in partnership with another property owned by a brother. Since the termination of the partnership in 1978, 'Peggioh' has been farmed as a single, completely pastoral unit. During that time an intensive development programme has been undertaken with the help of finance from the Land Development Encouragement Loan scheme (L.D.E.L.), the Livestock Incentive Scheme (L.I.S.) and the Rural Bank. The following is a summary of the policies, potential and problems of development in this summer dry environment.
SOME EFFECTS OF TOPDRESSING PASTURE WITH SODIUM CHLORIDE ON PLANT AND ANIMAL NUTRITION
Authors: Smith G.S. , Young P.W. , O'Connor M.B.
Published: July 2020

A long term study is being made of the effects of replacing all or part of the fertiliser input of potassium chloride (muriate of potash - KCI) with sodium chloride (common salt - NaCI) on plant and beef animal nutrition. The ryegrass-white clover pasture which is growing on a sodium deficient pumice derived soil (Taupo sandy silt), had received heavy applications of KCI over the preceeding 10 years. Results from the first two years show that because of the already high potassium status of the pasture, neither KCI or NaCl had any effect on pasture dry matter production or species composition, but did effect the chemical composition. Topdressing with NaCl at rates of 100-200 kg/ha/vr significantly increased the herbage sodium concentrations, while similar rates of 'KC1 increased potassium concentrations but decreased sodium concentrations. However, the depressing affects of KC1 on sodium concentrations were offset by applying 50 kg/ha/yr of NaCI. increasing the sodium concenrrarron In me neruaye au"ve V, I 70 VI LIIG UIY IUU~LLXZI with NaCl had a beneficial effect on the growth of weaner beef animals. However, increasing the sodium intake of beef breeding cows grazing pastures high in potassium had a detrimental effect on the concentration of magnesium in the blood serum. Thus, as a relatively high intake of sodium may induce metabolic problems in breeding cows, topdressing pastures or direct supplementation of animals with NaCI, should not be undertaken without sound evidence of its necessity particularly in areas prone to grass staggers (hypomagnesaemic tetany). Key Words: animal nutrition, herbage sodium; plant nutrition; potassium chloride; ryegrass-white clover pasture, sodium chloride, serum magnesium.
BIRDSFOOT TREFOIL (LOTUS CORNICULATUS) AS A POTENTIAL DRYLAND HERBAGE LEGUME IN NEW ZEALAND
Authors: Scott D. , Charlton J.F.L.
Published: July 2020

Observations in trials over a decade are now showing that birdsfoot trefoil (Lotus corniculatus) has the particular characteristics of high persistency and continued production under moderate soil fertility conditions on drier hill and high country sites. Hence it may have a role in the agriculture of such areas, probably as late summer or autumn feed. The species is seen as a 'poorer land grazing lucerne' rather than as a hay species as it is overseas. One particular disadvantage is likely to be its slow establishment from seed. In evaluations of introductions and overseas cultivars, some of the unselected introductions, showing early spring growth and an upright habit, performed better than cultivars. Keywords: Birdsfoot trefoil; Lotus corniculatus; infertile hill country; lucerne
A COMPARISON OF PERENNIAL GRASSES UNDER SHEEP GRAZING ON THE CENTRAL PLATEAU
Authors: Percival N.S. , Duder F.R.
Published: July 2020

Details are given on the production and survival over four years of five perennial grasses under rotational sheep-grazing on a pumice soil. The comparison involved three perennial ryegrasses ('Grasslands Nui and Ruanui', and Yates Ellett), and mixtures of Ellett with 'Grasslands Roa' tall fescue and Ellett with 'Grasslands Maru' phalaris. All pastures were sown with white and red clovers. Annual dry matter yields from Nui and Ellett pastures were similar, at about 6,500 kg/ha. Ruanui pastures were on average 600 kg/ha lower. The pastures containing tall fescue and phalaris were similar to Ellett. The major seasonal yield effects were in autumn and winter, when Ruanui pastures were substantially poorer than those with Nui and Ellett. Ryegrass yield of Ellett pasture was greater than Nui, and Nui was greater than Ruanui at all seasons. Ellett ryagrass was a higher proportion of the total yield at all times, and had higher tiller populations than Nui and Ruanui. Neither tall fescue or phalaris were, able to compete with Ellett ryegrass. It is suggested that neither of these be sown with ryegrass. Clover yields were higher in Ruanui than Ellett pastures, with Nui intermediate. The use of Nui, Ellett and Ruanui ryegrasses is related to the problems of seasonal distribution and total annual yields of pastures on the Central Plateau. It is suggested using Nui or Ellett as the base for perennial pastures will give substantial increases in production. Ellett ryegrass had higher survival than Nui which was considered an advantage, though this was achieved at the expense of a small reduction in clover vields.

BUMBLE BEE MANAGEMENT OPTIONS TO IMPROVE 'GRASSlANDS PAWERA' RED CLOVER SEED YIELDS
Authors: Macfarlane R.P. , Griffin R.P. , Read P.E.C.
Published: July 2020

Three options of bumble bee management for red clover pollination are discussed: spring supplementation with queens caught outside the locality; colony introduction at flowering; and permanently sited hives close to the crop. The first two options must be carried out annually whereas the last option presupposes an adequate local food source prior to flowering. It is contended that even with successful permanent siting further annual introductions would be required where the area in crop is to be considerably increased. Details of hive construction, field placement and colony management are outlined. In 1982 the amount of seed set, on a machine dressed basis, for one colony of B. hortorom and B. ruderatus was 130 kg and 56 kg respectively Keywords: Pawera red clover, seed yields, Bombus hortorum, B. ruderatus, hive construction, colony management.

LOLIUM ENDOPHYTE LEVELS IN COMMERCIAL PERENNIAL RYEGRASS SEED LINES
Authors: Scott D.J.
Published: July 2020

A survey of perennial ryegrass seed lines received for testing in 1982 revealed different Lolium endophyte infection level characteristics for different cultivars. Grasslands Ruanui had low infection levels, Ellett had high and Grasslands Nui and other perennial ryegrass samples had variable infection levels. Differences in infection levels are ascribed to the infection status of the original cultivar material and the storage period between harvest and sowing during the seed multiplication process. The problems associated with providing a seed testing service for Lolium endophyte are also discussed.
LUCERNE SEED PRODUCTION IN NEW ZEALAND - ACHIEVEMENTS AND POTENTIAL
Authors: Dunbier M.W. , Wynn-Williams R.B. , Purves R.G.
Published: July 2020

For New Zealand's lucerne seed industry to develop it must reliably produce seed at a price competitive with seed produced overseas. To achieve this will require increased specialisation and co-operation from all parts of the industry including breeders, growers and merchants. Recent research has resulted in a management package which will allow specialist growers to achieve consistently high yields and financial returns that will make seed production a specialist industry rather than a "catch crop" as in the traditional pastoral system. A trial at Lincoln to investigate the seed production capabilities of different cultivars showed there were no significant differences in yield between any of the cultivars currently being grown for seed in New Zealand. With the introduction of more efficient pollinators of lucerne, seed production may shift away from the traditional areas of Marlborough and into areas with more moisture retentive soils and areas where irrigation is possible. It is speculated that if changes do not occur in the lucerne seed industry then all of New Zealand's seed will be imported by 1990. Key Words: lucerne, Medicago sativa, seed production, cultivar

Adult Perceptions of Student Involvement in Schoolyard Gardening
Authors: Zhang Donia
Published: July 2020

The purpose of this research is to investigate through adult perceptions what factors have enabled and limited student participation in schoolyard gardening, and how to support student involvement in schoolyard gardening. It is a collective case study of three schools in Toronto District School Board (TDSB, Ontario, Canada). Sixteen interviews were conducted in 2005. The results show that the common factors that enabled student participation in schoolyard gardening are teacher’s initiative and commitment, principal’s leadership and support, parental involvement and donations, and the TDSB’s EcoSchools program and workshops. The common limiting factors are time, money, and the Union’s work-to-rule issue. The ways to support student involvement include teachers integrating gardening into the curriculum; parents making donations and creating a family gardening culture; principals supporting in budget and taking the lead; TDSB providing funding, awards, incentives, and more maintenance; and Ontario Ministry of Education supplying funding, curriculum link, and teacher training.

REGULARITIES OF THE PROCESSES OF FORMATION OF THE STRUCTURE AND STRENGTH OF A CLINKER-FREE BINDER OF ALKALINE ACTIVATION
Authors: Nahaev M. , Salamanova M. , Ismailova Z.
Published: July 2020

resource- and energy-consuming Portland cement is currently considered the most popular material in the construction industry, but its production can be attributed to the category of harmful industries in terms of the amount of emissions into the environment. Therefore, the development of a clinker-free technology for the production of binders based on mineral fine powders of aluminosilicate nature activated by an alkaline coater is a relevant and promising direction.

In the work, the laws of the processes occurring during the structure formation of clinker-free binder systems of alkaline activation on alkaline cements using blast furnace granulated slags in a finely dispersed state are studied. Formulations are given and the properties of clinker-free binders of alkaline activation on mineral fine powders from rocks of sedimentary and magmatic origin are investigated. Electron probe studies and X-ray phase analysis revealed the presence of hydrated amorphous compounds close in composition to zeolites in cement stone. An analysis of the results allowed us to determine the optimal composition of clinker-free binder alkaline activation “silicified marl + volcanic tuff (70: 30%) + Na2Si03 + Na0H” with activity ranging from 42.0 - 54.5 MPa, depending on the conditions of hardening of the samples.

Published: July 2020

the depletion of natural deposits of traditional inert mineral raw materials (sand, gravel) used to create effective layers of the foundations of roads leads to the development and application of new technologies and alternative materials. One way to solve this problem is to use local raw materials. For the construction of the lower layer of the road basement local soils are often used. However, their use is associated with the development of a set of measures to increase their efficiency, such as stabilization (by the use of chemical additives) and/or strengthening (by the introduction of various types of binders). In this regard, the paper analyzes the physicomechanical characteristics of reinforced clay soils obtained by introduction of various types of stabilizing additives in the presence of an inorganic mineral binder of hydration hardening type - cement - taking into account the recommendations for the used additives. The object of research was the most common representative of clay soils of the Belgorod region – heavy dusty clay loam. As a result of the studies, the authors established the reasonability of the use of the additives in the presence of cement, the most effective compositions of the reinforced soil were identified, contributing to the improvement of its controlled physical and mechanical characteristics. In addition, the need for additional studies to adjust the recommended composition of reinforced soil was established.
MAKING PRODUCTION DECISIONS USING THE EXPERT ASSESSMENT PROCEDURE
Authors: Ismailov R.
Published: July 2020

the article deals with the problem of making industrial decisions related to the construction of industrial facilities. The scheme of decision-making is presented, with consideration of its individual components. A method of collective decision-making is proposed for use on a construction site. In general, the idea of using collective intelligence in terms of solving production tasks is justified from the position of objectivity of conclusions. The essence is to obtain estimates for the required number of properties, based on the experience and knowledge of a group of individuals united in a single commission. If the procedure for creating an expert commission and processing the results of expert evaluations is followed, this method becomes a tool for relatively quick decision-making.

The research was based on the work of a number of authors who worked on the problem of expert decision-making methods. The article describes the main stages of applying expert assessment of properties. Various methods of acceptance, processing and output of the examination results at all stages of the survey are presented.

A conceptual scheme for organizing an expert commission was created. A distinctive feature of the project is the setting of a task for specialists, in the interpretation necessary for production. This means that for the same task, the expert, depending on a number of circumstances, can give opposite conclusions.

Based on the research, we can conclude that decision-making tools like the expert commission are in demand. This article shows how to use corrective formulas to turn a collective decision into a reasonable, objective answer to a question.
FREE AND FORCED VIBRATIONS OF SHELLS OF VARIOUS SHAPES, TAKING INTO ACCOUNT THE VARIABILITY OF THE NON-LINEAR ELASTIC MATERIAL
Authors: Sadygov I.
Published: July 2020

the article considers issues of shell vibrations, which are widely used in various industries and construction. Shells serve as elements of building structures with large spans.

The chapter “Introduction” discussed issues related to the use of shells in all areas of industry, in aviation, rocket and space technology, railway transport, in the oil and gas industry and provides examples of shells for use in ceilings of circuses, stations, hangars; in industry: shells of rotation used as tanks, containers, columns, reactors, etc. In the section “Materials and research methods” free and forced vibrations of shells of variable thickness made out of nonlinear elastic material reviewed. In shell calculations the Kirchhoff – Law hypothesis was used. It was found that, during vibrations, the shells experience relative deformation of elongation and shear of the surface with coordinates (x, y), as well as bending and torsion strains. It is established that vibrations in the shells lead to a rotation of the main directions of elasticity and regarding to the adopted coordinate axis to angle θ, and the elastic constants of the material depend on the elastic constant Biy – the main directions of the nonlinear elastic shells.

When solving the system of equations of motion of the shell relative to the displacements arising in it during vibration, based on theory R and various methods. The values of the dimensionless frequency parameter for a spherical shell taking into account changes in its curvature, variability and thickness of elastic properties are obtained.
ENERGY METHOD BASED ON THE STABILITY OF THE FLAT SHAPE OF THE CANTILEVER STRIP BEND TAKING INTO ACCOUNT ITS OWN WEIGHT
Authors: Yazyev S.
Published: July 2020

the problem of bending a strip by a force applied at the end is not of practical interest. Such method of loading and securing the ends is interesting only because it is most convenient to implement it on experience, which makes it possible to verify the Prandtl theory. When conducting experiments, there is a need for two corrections: it is necessary to evaluate the influence of the self-weight of the strip and the effect of increasing or decreasing the point of force application. As we are talking about small corrections, it is quite enough to use only the first approximation for calculations. An effective version of the energy method is recommended. It is used to calculate rectangular cantilever strips for stability of a flat bending shape, taking into account its own weight. The essence of this variant of the method is to use the Lagrange variational principle instead of the condition for equality of the potential strain energy and the work of external forces. The proposed approach allows us to perform machine implementation of calculations and take into account an arbitrary number of members of the series. The presented solution of the problem for the cantilever beam takes into account its own weight and the action of concentrated force.

Lithium (Li) metal has been regarded as one of the most promising anode materials to meet the urgent requirements for the next-generation high-energy density batteries. However, the practical use of lithium metal anode is hindered by the uncontrolled growth of Li dendrites, resulting in poor cycling stability and severe safety issues. Herein, vertical graphene (VG) film grown on graphite paper (GP) as an all-carbon current collector was utilized to regulate the uniform Li nucleation and suppress the growth of dendrites. The high surface area VG grown on GP not only reduces the local current density to the uniform electric field but also allows fast ion transport to homogenize the ion gradients, thus regulating the Li deposition to suppress the dendrite growth. The Li deposition can be further guided with the lithiation reaction between graphite paper and Li metal, which helps to increase lithiophilicity and reduce the Li nucleation barrier as well as the overpotential. As a result, the VG film-based anode demonstrates a stable cycling performance at a current density higher than 5 mA cm
-2
in half cells and a small hysteresis of 50 mV at 1 mA cm
-2
in symmetric cells. This work provides an efficient strategy for the rational design of highly stable Li metal anodes.

A proposta considera a apropriação de dispositivos e artefatos tecnológicos/comunicacionais, artísticos e literários em suas mais diversas linguagens para produção, circulação e reconhecimento de sentidos sobre e a partir da Amazônia.
A TELA CONQUISTA DO AMAZONAS
Authors: Nguangu Kabuenge Nathan , Silva da Costa Alda Cristina
Published: July 2020

O artigo é uma tentativa de abordar a questão da Amazônia sob uma perspectiva que vai além dos binarismos analíticos branco/ não branco, europeu/ não europeu, desenvolvimento/sustentabilidade; cidade/campo, dominação/resistência, entre outros, construída a partir de uma crítica às reflexões da Formação Socioeconômica e Cultural da Amazônia, que coloca em segundo plano o ser na Amazônia. Opta-se pela perspectiva hermenêutica gadameriana e do ensaio “A origem da obra de Arte” de Heidegger (2012) para analisar a tela “A Conquista do Amazonas” (ACA). Parte-se da análise decolonial da tela, por meio do conceito “novo dualismo”, em que se problematiza a “raça” no intuito de transcendê-la e ontologicamente recolocar o ser no centro da análise. Conclui-se que é necessário subverter a ordem das discussões e reflexões, ou seja, não indagar por que a Amazônia e sua população são dominadas e exploradas, mas sim quem é o ser da Amazônia.
A ANTROPOÉTICA DE BRUNO DE MENEZES
Authors: de Souza Wanzeler Rodrigo
Published: July 2020

Tomando Belém como cenário principal para o contexto deste trabalho, tem-se, com o apogeu da comercialização da borracha e a criação do Museu Paraense, um incremento científico na região, que almejava ser a Paris na Amazônia. Neste período, Belém vai do ápice à crise da comercialização da goma elástica, turbulências sociais tornam-se mais frequentes e as desigualdades latentes. Este contexto não passa impune ao olhar de Bruno de Menezes. O intelectual se vale da sua escrita, artística e politicamente engajada, para desvelar e se opor ante as diferenças sociais. Uma escrita de rexistência que, assim como a ciência antropológica no mesmo período, busca dirimir as discrepâncias existentes no cotidiano das sociedades amazônicas. Desta maneira, a presente pesquisa intenta relacionar os caminhos da ciência antropológica com os de Bruno de Menezes para incluir o nome do intelectual belenense enquanto figura importante para a consolidação de um fazer antropológico na/da Amazônia.
ETNOGÊNESE E ESTRATÉGIAS TERRITORIAIS DO QUILOMBO DO ROSA, MACAPÁ/AMAPÁ
Authors: de Souza Silva David Junior
Published: July 2020

As comunidades quilombolas do Amapá iniciaram seus processos de etnogênese no início do século XXI. Este artigo objetiva refletir sobre o processo de etnogênese do Quilombo do Rosa. A metodologia de pesquisa baseia-se em etnografia realizada junto à comunidade. Para a produção da etnogênese em si, dois processos fundantes foram identificados: o primeiro, a mobilização, em 2002, contra uma mineradora, quando esta planejava depositar rejeito tóxico de mineração, nas terras da comunidade; o segundo, a implementação do Programa Brasil Quilombola. O universo simbólico e a autorrepresentação da comunidade são muito maiores do que a identidade que esta assume no contexto multiétnico de contato. Esta dimensão de sua identidade, a de remanescente quilombola, é levada a primeiro plano para viabilizar a comunicação com o Estado. A etnogênese, assim, tem o sentido de uma estratégia territorial, porém não resume todo o universo de significados da ancestralidade, memória e tradição da comunidade.

Este artigo analisa a percepção dos moradores do Acampamento Coragem, em relação aos impactos sofridos com a instalação da Usina Hidrelétrica de Estreito (MA). Busca evidenciar a visão dos ribeirinhos em relação aos impactos socioespaciais dos empreendimentos, considerando os conflitos ocasionados com a instalação da barragem na comunidade. Explora a compreensão das formas de organização social e política dentro de um acampamento, assim como identifica os problemas enfrentados pelas famílias atingidas durante a implantação da usina e após sua construção. A pesquisa é de natureza qualitativa, com observação participante e aplicação de entrevistas semiestruturadas. Os resultados apontaram que o sistema capitalista tem reproduzido as desigualdades sociais em nossa sociedade. Este trabalho contribui para a reflexão acerca das diferentes análises sobre as formas de desenvolvimento reproduzidas pelo Estado, como a ressignificação sobre territórios e seus processos de migração.
O ECOFEMINISMO E A RELAÇÃO ENTRE NATUREZA E MULHER
Authors: Aymoré Débora
Published: July 2020

A abordagem histórica e filosófica de constituição da modernidade demonstra, primeiramente, um saber-fazer que se realiza a partir de sua base na natureza e, posteriormente, como desenvolvimento de estratégias produtivas. Deste modo, é possível reconstituir alguns elementos da proposta ecofeminista, em especial aqueles que se dirigem à produção sem limites e à acentuada industrialização. Embora em consonância com outras abordagens feministas, já que o ecofeminismo se constitui como postura de resistência ao patriarcado e às relações de dominação, ressalta-se especialmente a relação entre natureza e mulher, que é mantida por suas repercussões positivas, tal como no reconhecimento da experiência das mulheres e na recuperação da consideração da biosfera como ativa e necessária à sobrevivência dos seres humanos.
A VELOZ DILAPIDAÇÃO DA INFLUÊNCIA ITALIANA NA ARQUITETURA CIVILDE BELO HORIZONTE, MG –BRASIL
Authors: de Almeida Freitas Marcel
Published: July 2020

Nos últimos anos a especulação imobiliária em Belo Horizonte está rapidamente descaracterizando diversas regiões da área central, bem como alterando a paisagem tradicional dos bairros mais antigos. Com a verticalização da cidade, além da perda de qualidade de vida, há um empobrecimento estético e perda de referências edificadas importantes, como é o caso dos casarões construídos por mestre de obras anônimos, muitos deles imigrantes ou filhos de imigrantes italianos que vieram para esta capital no começo do século XX.
IDENTIDADE CULTURAL EM TIRADENTES (MG): TRADIÇÃO INVENTADA ELUGARES DE MEMÓRIA
Authors: Almeida Cunha de Castro Maria Luiza , de Oliveira Neves Clarissa
Published: July 2020

As cidades históricas convivem com o conflito entre a tentativa de preservação de seu patrimônio e a necessidade de inserção nas dinâmicas contemporâneas, contrapondo o enraizamento na tradição à “liquidez” que permeia a realidade atual. Este contexto exige a criação de novas identidades, que possam se estruturar dentro da dialética entre o passado e o presente. O objetivo deste artigo é interpretar as transformações pelas quais a cidade de Tiradentes (MG) tem passado, a partir das perspectivas desveladas pelos conceitos de “tradições inventadas” proposto por Hobsbawm e de “lugares de memória”, desenvolvido por Pierre Nora. Destaca-se, neste caso, o papel dos festivais e eventos– em especial a Mostra de Cinema – na construção de uma nova identidade, que articula história e contemporaneidade.

Authors: Rodrigues de Oliveira Adriano
Published: July 2020

O artigo propõe uma análise das gravuras que ilustram as amazonas no Novo Mundo, sobretudo no decorrer do século XVI e início do século XVII. Por um lado, aborda os elementos simbólicos das imagens e, por outro, aspectos do imaginário medieval/renascentista presentes na iconografia do referido período. Além disso, o presente estudo busca explorar a relação entre o texto escrito, de diversos gêneros – narrativas de viagem, crônicas, cartas, diários, e as figuras que estampam esses mesmos conteúdos, averiguando os componentes concordantes e conflitantes na confecção do conjunto texto/imagem. Pondera ainda, a transposição do mito grego para o contexto quinhentista, enfatizando os principais ingredientes do imaginário antigo e seu ressurgimento na conjuntura do Novo Mundo.
REPRESENTAÇÃO DA FEMINILIDADE POR MEIO DO STAR SYSTEMNORTE-AMERICANO NA REVISTAALTEROSA(1939-1945)
Authors: Arruda de Barros Gelka
Published: July 2020

Este artigo analisa a estratégia discursiva presente na revista Alterosa com o intuito de compreender a representação da feminilidade por meio do star systemnorte-americano, entre 1939 e 1945. A primeira seção aborda, brevemente, algumas relações entre o rádio nacional e o cinema norte-americano apresentando a construção de imagens modelo das rainhas do rádio e das estrelas de cinema. A investigação trata dos atributos e dos comportamentos desejáveis para a conformação da feminilidade voltada para a valorização da ordem conjugal. A segunda seção apresenta o entrelaçamento das noções de beleza e saúde como elementos de mobilização feminina para a prática de exercícios físicos e para o chamamento de guerra, analisando como esses discursos dirigiam a mulher para a maternidade sadia e para o cuidado com o outro.
