THEORETICAL ASPECTS REGARDING THE RELATIVE MOTION OF SEEDS ON AN INCLINED VIBRATING PLANE SURFACE
Authors: CĂSĂNDROIU TUDOR , BUCIUMAN FLORINA VIRGINIA , MOIS VICTOR
Published: October 2018

The trajectories described by the seeds on the planned double inclined surface play an important role in sorting seeds by density on the vibrating tables. The article develops the mathematical models of the particles trajectory supported by friction on double inclined plane surfaces subject to a motion by rectilinear translation harmonic oscillation and it emphasizes the difference between the particles trajectory with various friction coefficients. The values of such friction coefficients are in accordance with the variable density of the seeds which thus entails different places of seeds collection by their density on one of the sides of the surface.

All municipal sewage treatments using classic treatment chain create an amount of organic sludge. The stabilization/neutralization of them is essential before any conditioning or reuse. For agronomical recycling or energy-giving optimization, the sludge needs to correspond to some standards. That's why, it exist several treatment of stabilization, packaging and water extraction of sludge. This study deals with sludge chemical conditioning by flocculation process. In the first hand, the flocculation process allows to break up colloidal aversion between particles in sludge. This process is possible by charge neutralization thanks to synthetic or natural organic flocculation which is often cationic since the ionic force of sludge particle usually is negative and the flocculants can be used with lowest dose than common coagulant like aluminum sulfate or ferric chloride. Thanks to laboratory experiments by analysis of several doses of synthesis cationic flocculants, it has been possible to get performance on total suspended solids (TSS), by spectrophotometry measurement and consistency of sludge cake. Graphical analyses allow making comparison between some organic cationic flocculants and select the best one for this type of sludge and the kind of treatment used. The aim is to improve quality of sludge, quantity of filtrated volume, and quality of water.

Published: October 2018

In Kinshasa in general and in the commune of Limete in particular, the problem of waste management have become an important concern. Significant problems with the waste management are very common in the majority of the streets. The analysis from this study shows that all visited landfills are uncontrolled and not respect any regulations on management of urban solid waste. These discharges show a lack of enforcement of waste management policies without participation of the population in the resolve of the waste management problems. Most landfills are located in residential areas, along rivers, along public units, even school routes, hospitals and churches. This study reveals the major problem in the waste management in the commune of Limete. This is a negatively aspect of the low implication of the authorities, noncooperation of the population caused mainly by the precarious information.

Authors: AJAYI-BANJI ADEMOLA AJAYI-BANJI
Published: October 2018

Applicability of coconut husk char in heavy metal removal was examined in the study. The surface morphology and elemental compositions of the char was investigated with SEM-EDX machine. Heavy metals sorption on 100 g of the char dosage was studied under five different contact times in the column experiment. Isotherm and kinetic models were the probing tools for biosorption mechanism prediction. Results indicated removal efficiency for chromium, cobalt, cadmium, aluminum and arsenic at 60 mins contact time were 72, 80, 86, 89 and 100 % respectively. Contaminate removal depends on metal involved and sorption contact time. Adsorption data are fitted well into Freundlich isotherm model (R2 > 0.92). Pseudo kinetic second order well described the adsorption process, with most R2 values ≥ 0.94. Coconut husk char is an effective biosorbent in sequestration of arsenic, cadmium, aluminum and cobalt in contaminated surface water.

Authors: IULIANA IAȘNICU (STAMATE) , OVIDIU VASILE , RADU IATAN
Published: October 2018

Plates known as sound absorbing materials: textiles recovered fabrics plus polyethylene are made layered composite material intended to be used to encapsulate industrial engines, as sources of noise in the production departments. Influence of thickness sound-absorbing material can be supported by the values obtained for the absorption coefficient, but it can be studied as a study case in the anechoic chamber, where the sound pressure level is measured with a sound level meter. Cases captured: a free engine; the engine placed in a metallic cube and motor inserted; metal cube that was doubled separately with one material and then with the composite material proposed. For each situation are eight determinations on the perimeter of a circle with a radius of one meter from the source of the noise. Plot a graph of experimental results that support the idea: greater thickness of the layer of material will cause a better absorption of noise.

This article presents the methodology for determining the real values of kinematic indices which characterizes the mechanical separation of a mixture of solid particles. Mechanical separation of a mixture of solid-solid on surface provided with holes is the most common method of separation. To optimize equipment that performs this operation, both theoretical and practical characteristics are determined. Kinematic indices are part of the theoretical characteristics, helping to identify behavior of solid particles on a surface flat swing. Starting from an experimental batch, real values of the kinematic indices corresponding to up, down and sideways movement on the sieve were determined for the following types of real particles: grain, large grain beans, small grain beans and soybeans.

Authors: Rono Justice K. , Cheruiyot Erick K. , Othira Jacktone O. , Njuguna Virginia W.
Published: October 2018

Sweet sorghum (Sorghum bicolor L. Moench) contains fermentable sugars in the stem that can be converted to ethanol. The current study aimed at evaluating the performance of three sweet sorghum genotypes with five checks and contributes towards availing suitable sweet sorghum for industrial ethanol production. Field studies were carried out in Kenya at varied locations in a randomized complete block design with three replications. Sorghum was harvested at hard dough stage of grain development and evaluated for several stem juice production traits including plant height, cane yield, juice volume, degrees Brix, total, reducing, and non-reducing sugars, and ethanol yield via juice fermentation. Analyses of variance using SAS version 9.1 showed a significant effect of genotype for morphological characters and ethanol yield. Genotype EUSS10 produced the greatest cane (27.4 T/ha) and juice yield (7806.7 L/ha) whereas ACFC003/12 recorded the greatest ethanol yield (423.1 L/ha). At all sites, EUSS10 had the greatest plant height and days to 50% heading whereas SS04 had the greatest Brix and total sugar concentration. The greatest grain yield and non-reducing sugar concentration was produced by SS17 and SS21, respectively. Results of this study show that though Brix and total sugars are desirable for ethanol yield, cane yield, and juice volume of sweet sorghum determines the ultimate volume of ethanol produced.

Active Vibration Control of Cantilever Beam by Using Optimal LQR Controller
Authors: Mohammed Hadeer Abd UL-Qader , Wasmi Hatem Rahem
Published: October 2018

Many of mechanical systems are exposed to undesired vibrations, so designing an active vibration control (AVC) system is important in engineering decisions to reduce this vibration. Smart structure technology is used for vibration reduction. Therefore, the cantilever beam is embedded by a piezoelectric (PZT) as an actuator. The optimal LQR controller is designed that reduce the vibration of the smart beam by using a PZT element.  

In this study the main part is to change the length of the aluminum cantilever beam, so keep the control gains, the excitation, the actuation voltage, and mechanical properties of the aluminum beam for each length of the smart cantilever beam and observe the behavior and effect of changing the length of the smart cantilever beam. A cantilever beam with piezoelectric is modeled in Mechanical APDL ANSYS version 15.0 and verified this by using experimental work. The AVC was tested on a smart beam under different control gains in experimental work and chose the best control gain depending on FEM results for each length of the smart beam. The response of the smart beam is noticed to be different for every length and the reduction percentage for settling time was different for every length.

Is math in harmony with existence? Is it possible to calculate any property of existence over math? Is exact proof of something possible without pre-acceptance of some physical properties? This work is realized to analysis these arguments somehow as simple as possible over short cuts, and it came up with some compatible results finally. It seems that both free space and moving bodies in this space are dependent on the same rule as there is no alternative, and the rule is determined by mathematics.

It Takes Two: The Round-Robin Methodology for Investigative Interviewing Research
Authors: Hudson Charlotte A. , Satchell Liam , Adams-Quackenbush Nicole M
Published: October 2018

This is the post print of the paper accepted in Frontiers in Psychology: Forensic and Legal Psychology on 22nd October 2018. Investigative interviews are complex, dyadic, social interactions typically studied by evaluating interviewers’ questioning strategies. In field settings, interviewers naturally vary in their interviewing practice. Thus, it is important to conduct research reflective of idiosyncrasies in witnesses, interviewers, and the resulting unique pairings. This study explored sources of variation in an interview by using a ‘round-robin’ design. Each session of the study involved five witnesses observing five separate events. Witnesses were then simultaneously, but independently interviewed by four different interviewers, or completed a self-administered written interview. This sequence was repeated until each witness had seen every event and had been interviewed by each interviewer. Over nine sessions (N = 45) this produced 225 total interviews. Individual interview performance (accuracy and level of detail) as well as experience (subjective ratings) were then analysed in relation to the typical performance of the interviewer, the witness, the event, and the unique paring. We found that witnesses and interviewers could have an effect on statement quality, however the unique interview experience variance had the greatest influence on interview performance. This study presents the round-robin methodology as a useful tool to study realistic variation in interviewer, witness, and dyad behaviour.

Nocturnal Rhythms and Collective Practices
Authors: Diamanti Eleonora
Published: October 2018

Choreographies of assembly are grounded in the relationship between urban design and collective, bodily modes of reproducing, inhabiting, and reimagining urban space. Through a case study of urban regeneration, culture-led development, and social movements in Montreal, this article examines the particular nocturnal spatio-temporal rhythms of gathering in public space. For a long time, the night was left in the shadows by urban development experts who focus their attention on daytime plans and activities. However, following the rise of nighttime economies, sleepless societies, and ‘24/7’ cities, the night has received increasing attention since the 1990s (Crary; Gwiazdzinski and Straw). Critical engagements with the night as an object of study have shed light upon temporality, rhythms, and links between space and time. Such perspectives rethink urban life in terms of rhythm. Drawing from Henri Lefebvre’s theory of “rhythmanalysis,” this article focuses on the aesthetic, bodily, and sensorial experiences of collective practices. This article takes up Lefebvre’s notion of polyrhythmia—the idea that the living body is an association of a multiplicity of rhythms—to study the polyrhythmic qualities of collective and bodily practices in urban space at night. This night-focused study draws out the complex relations between collectivity, movements, and urban design. Moreover, a rhythmic study of the city at night foregrounds the multimodal perception process, following James Gibson’s theory of ecological perception. Hence, this article asks: how does the night affect our collective experience of the city?

As medidas protetivas de urgência previstas entre os artigos 18 a 24 da Lei nº 11.340/2006, Maria da Penha, intentam proteger a mulher vítima de violência em ambiente doméstico e familiar da iminência de continuidade da lesão ou ameaça de lesão aos seus direitos. Nesse sentido, toma-se por base uma análise de Parecer do Ministério Público do Maranhão, Processo nº 11437-60.2015.8.100001, que, ao relacionar esta demanda na vara de família com outras referentes ao mesmo conflito familiar existentes na Vara Especializada de Violência Doméstica e Familiar da comarca de São Luís – MA pugnou, dentre as medidas a serem aplicadas, pela reeducação do agressor, praticante de violência psicológica e assédio processual. Intenta-se observar a possibilidade processual de se aplicar a reeducação como medida protetiva de urgência, a fim de se alcançar maior eficácia na proteção das mulheres vítimas de violência doméstica, bem como possibilitar a prevenção da ocorrência de novos tipos de violência, independentemente de existência de ação penal e de uma possível futura condenação.
LOS ARCHIVOS DE LA RACIONALIDAD MODERNA: LAS PREGUNTAS DE MICHEL FOUCAULT POR LOS ESTATUTOS DEL SABER Y POR LOS CUERPOS BIOPOLÍTICOS
Authors: Sánchez Cecília
Published: October 2018

Este artículo se propone desarrollar algunos aspectos de las rutas y desvíos experimentados por Michel Foucault acerca de lo que entiende por políticas de la verdad en el marco de una crítica a la racionalidad moderna. Este recorrido es necesario para juzgar los motivos que lo llevan a desarrollar su enfoque de la “biopolítica” y su repercusión en la concepción política del cuerpo contemporáneo. Con relación a las controversias y apoyos que suscita esta perspectiva, señalaremos la implicancia de la biopolítica en el pensamiento de autores como Giorgio Agamben, Judith Butler y también en el pensamiento latinoamericano más reciente, me refiero al uso de la biopolítica y de otras categorías foucaultianas en el pensamiento de Santiago Castro-Gómez. Al finalizar, se examinan las nuevas posiciones que ocupa el intelectual cuyo pensamiento arranca de las políticas de la verdad y ya no desde la verdad. En especial, se consideran las críticas de Foucault a Sartre y Habermas, así como las críticas de Dussel y Bhabha al eurocentrismo de Foucault.
MAIN TENDENCIES AND POSSIBILITIES OF CHANGE OF EXPORT SPECIALIZATION OF RUSSIA
Authors: ZDOROV M.A.
Published: October 2018

Topicality. The relevance of change of export specialization of Russia has paramount character. Methodical approaches to an economic assessment of recreational resources of the region are considered (rent, expensive, standard, etc.), their critical evaluation is given, and expediency of application of a complex method of an assessment is proved. It consists in group of all existing methods and allocations of indicators of efficiency by each group of methods. The system of calculation of an integrated (complex) indicator of an economic assessment of recreational resources is given.Aim and tasks. For stimulation of agrotourist activity in the Russian Federation we conducted researches on measurement of agrotourist capacity of the economic region of Russia united in the North-South program for a long time. Tasks of identification of agrotourist capacity of regions at respect for the principles of territorial division of labor were set, and according to rationalization of placement and specialization of branches.Research results. Import substitution of food opens ample opportunities for entrance tourism which is a peculiar form of export of food production and tourist's services. It especially is important that organic production often is perishable (hot bread, pair milk, cottage cheese, sour cream, etc.). From this it follows that tendencies of small farms in the village (LE, K(F)H, SPK, etc.) on reception of foreign tourists have the prospects. The interests of the tourists wishing to get acquainted with the multinational culture of Russia features of national crafts and crafts, dream natural places are many-dimensional complemented with consumer goods in the form of organic production.As a result of carried out researches it has turned out that indicators on tourism and agrotourism have coincided. The economic sense is quite explainable here. In the future prospect, it is expedient to transfer all internal and entrance tourism to agrotourism or tourism of rural territories, there is an insignificant part of a tourist's product in the large cities of regional value. Agrotourism on the international standards includes the small and average cities, reflecting all means of placement, natural and cultural and historical potential.Conclusions. As a result of a research, it is possible to draw a conclusion that today the scheme of the movement of financial resources - from tourist to the agricultural enterprises is of particular importance. The calculations which are carried out according to this scheme allow to define for three-year term limits of multiplicative stability of agrotourist production, components 5,9 and 11,7 trillion rubles.

Eighteen (18) species of hover flies (Insecta:Diptera:Syrphidae) under 14 genera and 2 subfamilies has been reported from the Cold dry zone of Himachal Pradesh which includes Kinnaur, Lahul & Spiti and Pangi range of Chamba districs. 4 species namely Chrysotoxum violaceum Brunetti, 1923, Sphiximorpha triangulifera (Brunetti, 1913),Mallota (Mallota) orientalis (Wiedemann, 1824), Mallota (Mallota) varicolor(Walker, 1856) has been reported from the first time from this cold and dry zone zone as well as from the state of Himachal Pradesh. Their taxonomic keys and detail diagnosis of the reported species has been discussed along with the distributional pattern of these species along the cold dry zone of Himachal Pradesh.
REVISITING DURABILITY OF BRIDGE SOLID PIERS
Authors: Bokarev S. A. , Zasukhin I. V.
Published: October 2018

The paper presents data on the prevalence and service life of solid piers of railroad bridges of the Russian Railways. The dynamics of solid pier damages, the development of normative documents on assessing their technical conditions and durability, and methods of assessing the residual life of bridge structures are shown herein. Information on the threshold values of failure is also given. The residual life of the intermediate masonry support is analyzed and estimated using two standard techniques. Their similarities and differences are determined and their limitations are compared. Proposals are made to clarify the damage parameters described in the current normative document for assessing the technical condition of railway structures. For statistical data processing in relation to bridge damages and prediction of their development, a model is proposed on the basis of semi- Markovian process. Possible data sources for constructing such a model are indicated. An alternative model for estimating the reliability of bridge structures is shown.
Bipolar bozuklukta Etkin Olan PsikolojikMekanizmalarınAnlaşılması: Duygusal ve BilişselSüreçler Üzerine bir Vaka Örneği
Authors: SAFRANCI Başak
Published: October 2018

Bipolar bozukluk günümüzde iş yaşamı, sosyal yaşam ve insan ilişkileri üzerinde oldukça yıkıcı etkileri olan yaygın ve kronik bir durum olarak kabul edilmektedir. Klinik raporlarda kaydedilen geç ya da yanlış tanı oranının yüksekliği, başarısız tedavi sonuçları, eşlik eden diğer sorunların sıklığı ve yüksek intihar oranları, bipolar bozukluğun tanı ve tedavisinde devam eden sorunlara işaret etmektedir. Bu sorunları çözme amacıyla yapılan çalışmalar, sadece biyolojiye indirgenen bir bakış açısının bu hastalığı anlamada yeterli olmadığını göstermekte, sınırlı bilgiyle yapılan farmakolojik tedavilerin de yetersiz kaldığını vurgulamaktadır. Bu amaçla, bu çalışmada bipolar bozuklukta bilişsel ve duygusal faktörleri içeren psikolojik dinamiklerin rolü ve bu roller üzerinden yapılandırılan psikoterapinin bipolar bozukluk seyrindeki etkisi araştırılmış ve vaka örnekleri verilmiştir.
HYPOGLYCAEMIA AS A CONSEQUENCE OF PRE-OPERATIVE FASTING: MYTH OR REALITY?
Authors: DG Nwosu Arinze , A Nwobi Emmanuel , E Obi Ikechukwu
Published: October 2018

Background: The fatal risk of pulmonary aspiration of gastric contents during anaesthesia had since been recognized and consequently preoperative fasting guideline is usually prescribed to prevent this. Concern about development of hypoglycaemia during prolonged fasting has often been expressed, especially in children. AIM: This study is intended to determine the fasting blood glucose in preoperative patients of different age groups who were fasted for varying duration of time, and determine whether indeed hypoglycaemia occurs during inadvertently prolonged fasting which we often encounter in our practice setting. Methodology: A prospective cohort study of fasting blood glucose (FBG) of patients presenting for elective surgery in the principal investigator's operating rooms at the National Orthopaedic Hospital, Enugu, Nigeria was carried out. Blood glucose meter was used for estimation of glucose in capillary whole blood of the patients and the obtained data were analysed using SPSS version 16.0 statistical software. Comparison of mean values was done using the Chi-square test with statistical significance put at P < 0.05.  Results: Out of one hundred and thirty three patients studied with mean age of 30.2 ± 19.60 years (range: 1-72 years), and mean duration of fasting 12.73 ± 2.01 hours, (range: 8-16 hours), the mean fasting blood glucose was found to be 91.49 ± 13.36mg/dl (range: 58 - 124mg/dl). No relationship was found between age and FBG (Pearson's correlation coefficient, r = 0.025). Likewise duration of fasting did not relate with FBG (Pearson's correlation coefficient, r = 0.088). One patient (0.8%) had hypoglycaemia, with blood glucose of 58mg/dl. Conclusion: Hypoglycaemia as a consequence of pre-operative fasting is rare, even in non-infants fasted for considerably long hours. Neither patient's age, gender, nor duration of fasting had any significant influence on the fasting blood glucose of the patients.
