Published: May 2019

Air limbah yang dihasilkan dari kegiatan rumah tangga jika tidak dikelola dengan baik maka akan menimbulkan masalah yang serius bagi lingkungan. Salah satu solusi dalam mengatasi permasalahan air limbah, yang ada di Indonesia yaitu dengan menggunakan septic tank. Septic tank umum digunakan di Indonesia karena menggunakan prinsip anaerob, yang hanya dibuat kemudian dibiarkan saja, tanpa perawatan yang rutin, dan jika ingin operasionalnya optimal maka perlu dikuras dengan jangka waktu 1 kali dalam setahun. Penelitian ini bertujuan untuk mengetaui Perkiraan kualitas dari effluent (BOD & COD) septic tank dan Berapa kapasitas volume dari septic tank untuk rumah tempat tinggal. Metode penelitian Besaran air limbah yang dihasilkan dari kegiatan rumah tangga menuju septic tank menurut Jayanudin (2016), adalah sebesar 120 L/hari atau 0,12 m3/hari dengan jumlah anggota keluarga ideal yaitu 5 orang. Dalam penelitian ini, air limbah mengalir selama 12 jam yang berasal dari kegiatan rumah tangga. Kadar COD yang dihasilakan Effluent pada septic tank ini adalah sebesar 207 mg/ltr dan COD Removal rate sebesar 31,5%, sedangkan Kadar BOD yang dihasilkan Effluent pada septic tank ini sebesar 411 mg/l dan BOD removal rate sebesar 31,5%. Untuk Akumulasi Volume lumpur yang dihasilkan selama 2 tahun (24 Bulan) adalah sebesar 0,081m3. Penurunan volume lumpur/sludge pada septic tank sebesar 68% atau Setelah 24 bulan volume lumpur menjadi 0,055 m3, semakin lama waktu penyimpanan lumpur di septic tank maka volumenya akan semakin berkurang. Volume septic tank yang dibutuhkan untuk menginapkan limbah selama 15 jam adalah sebesar 0,075, Semakin lama waktu Hydraulic retention time (HRT)/waktu tinggal limbah, maka akan semakin baik penguraian mikroorganisme dalam septic tank serta sebaliknya, semakin singkat waktu HRT maka proses penguraiannya samakin tidak baik.

UMA FILOSOFIA DA GEOGRAFIA COMO NECESSIDADE METODOLÓGICA NA PROPOSTA TEÓRICA DE MILTON SANTOS
Authors: Silva Fernando Antonio
Published: May 2019

a reflexão sobre o método no interior da geografia pode ser feita, dentre as inúmeras possibilidades existentes, a partir da atualização de contribuições dispersas nas diversas ciências e na filosofia, além do resgate de proposições de teóricos da própria geografia, ou, ainda, com base em estudos, recorrentemente chamados de “empíricos, sobre um ou mais aspectos da dinâmica territorial (os sistemas técnicos e a integração do território, as novas dinâmicas urbanas, o papel da informação, as implicações territoriais das políticas públicas, todos estes são exemplos de temas de estudos atuais da ciência geográfica) – exercício que frequentemente se faz no âmbito da produção de uma tese, dissertação ou monografia. Problematizamos as possibilidades de encaminhar essas duas perspectivas de maneira não só paralela, mas, também, complementar. Para isso, o texto aborda, sucintamente, a importância da Metageografia na perspectiva de Milton Santos para uma correta condução metodológica da ciência geográfica. Advoga-se neste trabalho que o método envolve operações complexas e que, por assim ser, sua construção e utilização exigem uma filosofia da Geografia. Para tanto, nos baseamos no pressuposto defendido por Armando Corrêia da Silva (1980; 2000) para quem, dentro da totalidade social, a Geografia deve ser considerada uma subtotalidade. Mediante a breve reflexão ora apresentada pretende-se contribuir para o debate acerca do método geográfico.

Authors: Medeiros Francisco Hiályson Fidelis , Medeiros Wendson Dantas de Araújo
Published: May 2019

O presente artigo trata-se de um estudo sobre a dinâmica da paisagem do município de Martins/RN, (Nordeste do Brasil) com vista a analisar a evolução do uso e cobertura da terra entre os anos de 1994, 2004 e 2014, bem como avaliar as principais transformações ocorridas na paisagem ao longo do período determinado. Os procedimentos metodológicos estão apoiados na análise e interpretação de produtos de sensoriamento remoto em ambiente de Sistemas de Informações Geográficas-SIG por meio do uso do software Quantum GIS (QGIS®) e em pesquisa de campo. Foram aplicadas técnicas de classificação semiautomática de imagens do satélite Landsat, seguida por processos de revisão e correção manual, com base em seis classes de uso e cobertura da terra. Os resultados obtidos são apresentados em três mapas temáticos que apresentam a evolução das classes de uso e cobertura da terra ao longo do período analisado. Os dados apontam para uma tendência de modificação antrópica da paisagem por meio de um processo de expansão territorial em detrimento da redução de áreas naturais e em equilíbrio ambiental e paisagístico. Por fim, sugere-se a necessidade de criação de instrumentos de planejamento e gestão ambiental para a promoção de um ordenamento territorial mais adequado às características ambientais municipais.

Este estudo foi realizado em área inserida no ecossistema Savana-Estépica Arborizada, do bioma Caatinga, localizada no município de Campina Grande, estado da Paraíba. O objetivo deste estudo foi conhecer a composição florística e a estrutura da vegetação através de estudo florístico e inventário florestal em oito parcelas de 10 x 40 m, onde foram mensuradas todas as árvores e arbustos com diâmetro ao nível do solo > 2 cm e altura > 100 cm. Foram calculados parâmetros fitossociológicos, índices de Shannon (H’) e equitabilidade de Pielou (J). O estrato da vegetação predominante é o arbustivo, com alturas variando entre 1 e 2 m, com presença de árvores emergentes, cuja altura máxima é de 5 m. A área basal total foi de 2,94 m2.ha-1. A fitossociologia registrou uma diversidade baixa de espécies (n=20), com o valor de Shannon H’=1,89 nats.ind-1. As espécies vegetais de maior densidade foram Mimosa tenuiflora, Croton blanchetianus, Poincianella pyramidalis, Croton heliotropiifolius, Jatropha mutabilis e Piptadenia stipulacea. As espécies com maior valor de importância foram Mimosa tenuiflora, Ziziphus joazeiro, Croton blanchetianus, Poincianella pyramidalis e Commiphora leptophloeos. A florística registrou 65 espécies, entre árvores, arbustos, ervas, lianas e epífitas. Com os resultados concluiu-se que a vegetação encontra-se no estágio inicial de sucessão ecológica com diferentes graus de antropização.

Published: May 2019

O estudo que segue centra-se em uma discussão que toma como referência a trajetória intelectual de David Harvey, com enfoque nas suas contribuições para a ciência geográfica, destacadamente para as ideias inspiradas pela teoria marxista. Com base em pesquisa bibliográfica sobre a produção desse intelectual buscou-se mostrar como o pensamento marxista é tomado a análise crítica nos estudos empreendidos por Harvey sobre a dinâmica urbana no contexto de reprodução do capital. Associado a essa perspectiva, procurou-se mostrar como sua produção tem respaldado de forma relevante os estudos urbanos contemporâneos, e como tem se consubstanciando em importante referência para as ciências humanas, extrapolando, por conseguinte, o campo de estudo da Geografia.
IMPORTÂNCIA, HETEROGENEIDADE E POBREZA DA AGRICULTURA FAMILIAR NO ESTADO DO RIO GRANDE DO NORTE
Authors: Aquino Joacir Rufino de , Freire José Aldemir , Carvalho Augusto Carlos A. T. de
Published: May 2019

O objetivo deste artigo é analisar a importância socioeconômica e a heterogeneidade da agricultura familiar no meio rural do estado do Rio Grande do Norte (RN). Para tanto, utiliza dados e tabulações especiais do Censo Agropecuário 2006, do IBGE. Após apresentar um breve balanço da evolução da estrutura agrária potiguar, e discutir as suas especificidades à luz da literatura sobre o tema, o trabalho demonstra que a agricultura familiar é o setor predominante em número de estabelecimentos, pessoal ocupado e produção de alimentos no campo, embora detenha apenas um terço das terras agrícolas. Além disso, os dados trabalhados evidenciam que o segmento familiar norte-rio-grandense é caracterizado por uma marcante diferenciação interna, sobressaindo um elevado contingente de produtores pobres e extremamente pobres enquadrados no chamado Grupo B do PRONAF. Essas e outras evidências sinalizam que a agricultura familiar do RN não pode ser negligenciada, quer seja em termos analíticos, quer seja do ponto de vista das políticas públicas, sendo fundamental avançar na compreensão de suas diferentes dimensões a fim de planejar ações estruturantes visando à promoção do desenvolvimento rural no estado.

INTRODUCTION: This peer-reviewed hypothetical case was written to help the readership understand the challenges of dealing with quite common yet very debilitating diseases during space missions. This scenario is based on a real case of an astronaut who had previously flown in
space and developed acute pancreatitis after being dehydrated from wilderness survival training. Many astronauts experience life threatening illness and injury before and after flight and, as space missions become longer and more remote, it is only a matter of time before these events occur
during a mission. Future exploration space mission planners need to anticipate that these common catastrophic medical events will occur.CASE REPORT: You are a flight surgeon working on console at Mission Control during a long duration lunar mission. You have completed extensive
space, military, and civilian aerospace medical training to address almost any anticipated medical event and can summon advice from medical experts located around the world. One crewmember is a 37-yr-old man who just completed an 8-h moonwalk and now describes a constant 7/10 dull epigastric
pain with radiation around the left flank to his back. His pain is getting progressively worse and he is presently sitting with his trunk flexed and knees drawn up in extreme distress. Working with the flight director, you must decide in the next 12 h whether to recommend the multibillion-dollar
mission be aborted and have the crew return to Earth immediately to save your patient.Hamilton DR, McBeth PB, Greene MR, Kirkpatrick AW, Ball CG. Hypothetical case of pancreatitis during a long duration lunar mission. Aerosp Med Hum Perform. 2019; 90(6):570–578.
A Validated Method for Detection and Quantitation of 2’Fucosyllactose in Infant Formula Matrices
Authors: Prieto Pedro A. , Miklus Michael B. , Barber Cynthia M. , Tennyson Steven M.
Published: May 2019

Analytical methods to assess the content of free carbohydrates in solution range from simple tests of reductive power to combinations of chromatography and mass spectrometry. Soluble carbohydrates such as lactose, maltose, fructooligosaccharides, and galactooligosaccharides are commonly found in infant formulas either as sources of energy or soluble fibers. On the other hand, a rich repertoire of lactose-based carbohydrates occurs naturally in human milk.  The advent of novel biosynthesis technologies resulted in the availability of human milk oligosaccharide structures that are being used as ingredients in infant formulas.   Notably, 2’Fucosyllactose has been tested in preclinical and clinical studies to determine its safety and to explore its potential health benefits in the context of pediatric nutrition. Several chromatographic methods for the analysis of human milk oligosaccharides have been published and, the main challenge associated with 2’Fucosyllactose quantitation has been to improve its resolution from lactose, which is present at concentrations around 70 g/l in both, infant formula and human milk. We developed a high-performance anion exchange chromatography method to detect and quantify 2’ Fucosyllactose in the presence of lactose by expanding the elution time between these saccharides. We validated the analytical procedure which behaved linearly (average R=0.99951) at concentrations as low as 1.75 µg/ml (limit of quantitation) with an average limit of detection of 0.43 µg/ml.
A rejoinder to Tily
Authors: Lavoie Marc
Published: May 2019

As everyone knows, Keynes’s General Theory has generated a lot of different interpretations. Geoff Tily presents a brief statement of his own understanding of it in his comment to my paper and he questions my perspective. There are also different strands of post-Keynesianism, as I have myself explained in a number of places. Tily is closest to what has been called Fundamentalist Post Keynesianism. 
The Operation of Bucket Wheel Excavators When Encountering Inclusions with Excessive Mining Resistance
Authors: András József , Kovács József
Published: May 2019

The Bucket Wheel Excavator (BWE) is the main piece of harvesting equipment used in open-pit lignite or brown coal open-pit mines worldwide. Despite the continuous increase in size, productivity and technical sophistication in recent decades, they have not adapted to the changes of operating environment. In this respect, the increasingly frequent occurrence of hard inclusions – in terms of layers, boulders and other forms – has revealed a consistent failure of BWE-s to meet this challenge. This paper, inspired by the research project RFCR-CT-2015-00003-BEWEXMIN „Bucket wheel excavators operating under difficult mining conditions including un-mineable inclusions and geological structures with excessive mining resistance” deals with preliminary considerations and results that aim to contribute to solving this problem.
Mathematical and Assembly Modeling of The Mechanism for Implementing Intermittent Rotational Motion and Speed Setting of The Metering Shaft for Seed Drills
Authors: Forgó Zoltán , Tolvaly-Roșca Ferenc , Pásztor Judit
Published: May 2019

The metering shaft of the drilling machine is driven from the impeller. The standard traditional gearbox, the Norton gearbox, provides a constant rotating motion between the impeller and the metering shaft. Manufacturers have started to replace this gearbox with an intermittent rotating movement. Using the stepless variable speed gearbox, the speed of the metering shaft and thus the seed rate is set steplessly. The aim of the thesis is the mathematical modeling of the intermittent rotating motion of the seed drill of a particular drilling machine, and the creation of a striping model.
Moderization of Cortically Supported Individual Implants
Authors: Kulcsár Klaudia , Kónya János
Published: May 2019

Digital product processing, 3D and finite element analysis techniques, modern, tissue-friendly implants with adequate surface treatment and proper screw-fixing make it possible for a good idea to successfully treat patients who do not have a sufficient amount of bone tissue for the implantation of conventional cylindrical-shaped dental implants. The duration of the surgical procedure of a complete, toothless jawbone becomes much shorter. Complicated measurements and risky techniques that require substantial expertise become unnecessary. The implant can be placed precisely into position with a simple surgical procedure. Then, it can be fixed to the bone tissue with the help of pre-designed fixation points. After this, only the professional closing of the wound has to be carried out. We have designed and manufactured a titanium cortical implant that is novel both in the view of chemical composition and surgical procedure. The final connection shaping of the sleeve and abutment system of the personalized cortical-backup implants was designed with the help of finite element analysis methods after the healing process.
Textile-Reinforced Concrete Structural Elements
Authors: Libotean Dan Alexandru , Chira Alexandru , Gobesz Ferdinánd-Zsongor
Published: May 2019

The textile reinforced concrete is a material with increased mechanical properties that can allow the production of lighter structural elements. The alkali-resistant textile reinforcement is not affected by corrosion. A structural facade panel and a light pole were modeled in order to study their behavior in the case of wind pressure. The developed numerical simulations were calibrated according to available data from the literature. These simulations revealed information potentially useful in the planning of further experimental tests.
Issues of The Usability of Copper Ore (Chalcopyrite) From Bălan for Ustensiles Production in The Bronze Age
Authors: Márton László , Talpas János , Bitay Enikő
Published: May 2019

Archaeological publications connect the raw material used for the production of copper and bronze artifacts discovered during the excavations carried on in Szeklerland to the use of the chalcopyrite from the Bălan copper ore deposit. So far, this assumption has not been confirmed by concrete evidence. Men of the Bronze Age can’t possibly have had knowledge of the metallurgy of sulphide-type copper ores such as chalcopyrite. Applying investigations based on spectroscopy, the Bronze Age use of chalcopyrite from Bălan could be either confirmed or refuted, the new data throwing more light on the provenance of the bronze artifacts discovered in the Szeklerland.
The Deformaton of The Gear Hob’s Generating Surfaces Due to Re-Sharpening
Authors: Máté Márton , Hollanda Dénes
Published: May 2019

The side relief faces of the monolithic involute gear hob are machined through relieving. The resulting surfaces are bevel helical surfaces in which the side cutting edges result from the intersection of these with the helical rake face. Theoretically, the gear hob is derived from an involute worm. Resharpening decreases the diameter of the hob, thus the edges became closer to the axis, and as a consequence they will be situated on a smaller worm than the original. The present paper analyses the deviation of the re-sharpened gear hob’s carrying worm from the theoretically perfect involute worm whose characteristic dimensions were adjusted considering the re-sharpened gear hob characteristic diameters. It was proven that the evolution of the errors is significantly different from that described in the literature. Thus, increasing the new gear hob diameters in comparison with the calculated dimensions is unnecessary, because it cannot reduce the error to half with this procedure. The mathematical model was built up accepting that the edges result from the intersection of an involute worm with a helical rake face and the side relief faces result from the rototranslation of the edges on a bevel helix leading curve dressed by the relieving parameter.
Material Classification Based on Vibration Analysis
Authors: Al-Bkree Mahmod
Published: May 2019

In this paper, we investigate the characteristics of an object’s vibration in identifying its material of construction. A simple vibration test is performed to classify different types of materials. The test is done by performing small hammer excitation on the object then recording its vibration using one acceleration sensor. Four different materials were tested (steel, hardwood, softwood, and plastic). The vibration signal was analyzed using MATLAB based model. The trained model was able to recognize the testing samples of each material. The advantages of this method are that it is accurate, fast and simple, can be performed on-site and is relatively inexpensive.
Design of a Horizontal Anaerobic Reactor
Authors: Diószegi Mónika Bakosné
Published: May 2019

The economics of biogas plants have an impact on the justification of the industrial unit. The conditions of high-yielding high-quality biogas production are estimated on the basis of laboratory fermentation studies. In designing the laboratory fermenters, working conditions must be modelled. However, the biggest problem with the biological model is its size, because the magnitude is less than in industrial applications and therefore extremely sensitive to environmental influences. During the design, an important aspect is that the periodic mixing of the raw material can be done in the reactors as in the industry. This article shows the equipment based on empirical research.

Failure of Remanufactured Gears
Authors: Csorba Béla , Végvári Ferenc
Published: May 2019

Gears are torque and motion transmision elements required for gearboxes. Adequate consideration must be given to the material selection and heat treatment of these gears. Inappropriate material selection or heat treatment will lead to premature failure of the manufactured gears or early refurbishment. In our publication, we present a number of practical failures that can be traced back to wrong material selection or heat treatment operation.

Authors: Faitli Tamás , Tar József
Published: May 2019

While the forward kinematic task of robots can be solved easily through homogenous transformation matrices, the inverse kinematic task leads to difficulties as the construction of the system becomes more complex. In this paper, a solution has been worked out for a three Degree-of-Freedom (DOF) robot-arm based on recent research, by the use of a novel, fixed-point transformation based technique.
