Published: March 2020

Abstract. This study presents and discusses horizontal and vertical geodetic velocities for a low strain-rate region of the Southalpine thrust front in northeastern Italy obtained by integrating GPS, InSAR and leveling data. The area is characterized by the presence of sub-parallel, south verging thrusts, whose seismogenic potential is still poorly known. Horizontal GPS velocities show that this sector of the Eastern Southern Alps is undergoing ~ 1 mm/a of NW-SE shortening associated with the Adria-Eurasia plate convergence, but the horizontal GPS velocity gradient across the mountain front provide limited constraints on the geometry and slip-rate of the several sub-parallel thrusts. In terms of vertical velocities, the three geodetic methods provide consistent results showing a positive velocity gradient, of ~ 1.5 mm/a, across the mountain front, which can be hardly explained solely by isostatic processes. We developed a interseismic dislocation model, whose geometry is constrained by available subsurface geological reconstructions and instrumental seismicity. While a fraction of the measured uplift can be attributed to glacial and erosional isostatic processes, our results suggest that interseismic strain accumulation at the Montello and the Bassano-Valdobbiadene thrusts are significantly contributing to the measured uplift. The seismogenic potential of the Montello thrust turns out to be smaller than that of the Bassano-Valdobbiadene fault, whose estimated parameters (LD = 9.1 km and slip-rate = 2.1 mm/a) indicate a structure capable of potentially generating a Mw > 6.5 earthquake. These results demonstrate the importance of precise vertical ground velocity data for modeling interseismic strain accumulation in slowly deforming regions, where often seismological and geomorphological evidence of active tectonics is scarce or not conclusive.
Solar radiative transfer in Antarctic blue ice: spectral considerations, subsurface enhancement, inclusions, and meteorites
Authors: Smedley Andrew R. D. , Evatt Geoffrey W. , Mallinson Amy , Harvey Eleanor
Published: March 2020

Abstract. We describe and validate a Monte Carlo model to track
photons over the full range of solar wavelengths as they travel into
optically thick Antarctic blue ice. The model considers both reflection and
transmission of radiation at the surface of blue ice, scattering by air
bubbles within it, and spectral absorption due to the ice. The ice surface is treated as planar whilst bubbles are considered to be spherical scattering
centres using the Henyey–Greenstein approximation. Using bubble radii and
number concentrations that are representative of Antarctic blue ice, we
calculate spectral albedos and spectrally integrated downwelling and
upwelling radiative fluxes as functions of depth and find that, relative to
the incident irradiance, there is a marked subsurface enhancement in the
downwelling flux and accordingly also in the mean irradiance. This is due to the interaction between the refractive air–ice interface and the scattering interior and is particularly notable at blue and UV wavelengths which correspond to the minimum of the absorption spectrum of ice. In contrast the absorption path length at IR wavelengths is short and consequently the attenuation is more complex than can be described by a simple Lambert–Beer style exponential decay law – instead we present a triple-exponential fit to the net irradiance against depth. We find that there is a moderate dependence on the solar zenith angle and surface conditions such as altitude and cloud optical depth. Representative broadband albedos for blue ice are calculated in the range from 0.585 to 0.621. For macroscopic absorbing inclusions we observe both geometry- and size-dependent self-shadowing that reduces the
fractional irradiance incident on an inclusion's surface. Despite this, the
inclusions act as local photon sinks and are subject to fluxes that are
several times the magnitude of the single-scattering contribution. Such
enhancement may have consequences for the energy budget in regions of the
cryosphere where particulates are present near the surface. These results
also have particular relevance to measurements of the internal radiation
field: account must be taken of both self-shadowing and the optical effect
of introducing the detector. Turning to the particular example of englacial
meteorites, our modelling predicts iron meteorites to reside at much reduced
depths than previously suggested in the literature (< 10 cm vs.
∼ 40 cm) and further shows a size dependency that may explain
the observed bias in their Antarctic size distribution.
Brief communication: On calculating the sea-level contribution in marine ice-sheet models
Authors: Goelzer Heiko , Coulon Violaine , Pattyn Frank , de Boer Bas , van de Wal Roderik
Published: March 2020

Abstract. Estimating the contribution of marine ice sheets to sea-level rise is
complicated by ice grounded below sea level that is replaced by ocean water
when melted. The common approach is to only consider the ice volume above
floatation, defined as the volume of ice to be removed from an ice column to
become afloat. With isostatic adjustment of the bedrock and external
sea-level forcing that is not a result of mass changes of the ice sheet
under consideration, this approach breaks down, because ice volume above
floatation can be modified without actual changes in the sea-level
contribution. We discuss a consistent and generalised approach for
estimating the sea-level contribution from marine ice sheets.
Mobile health technologies and medical records
Authors: Wong Sean , Wang Wendy
Published: March 2020

Migrants and refugees often face healthcare difficulties that may be difficult to address in low-resource healthcare settings. They often present with multifaceted and complex health problems that pose unique challenges for both primary care providers and public health officials. Mobile health technologies (mHealth), which involves the use of mobile technology in order to support medical and public health practices, is currently being explored as a means of addressing some of these challenges. The rapid expansion of mobile technology and increasing ubiquity of devices such as mobile phones even in low-resource settings has made mHealth an attractive option for the provision and support of healthcare. mHealth has been implemented in novel ways to enhance patient education, support immunization, and monitor infectious disease in vulnerable populations. Despite its benefits, there remain limitations to the use of mHealth in low-resource healthcare settings, including concerns regarding personal health information security, user adherence, and validated implementation, amongst others. This article will explore the use of mHealth to support medical care in low-resource healthcare settings.
Best practices in refugee mental health
Authors: Quint Elise , Hawilo Hasan , Eaton Sydney
Published: March 2020

Canada has a long history of accepting immigrants and refugees. These populations may have unique health care needs that the Canadian health care system must adequately address. Currently, there are numerous barriers to the treatment of refugee mental health concerns. These include cultural, language, financial, and systemic barriers. Best practices for treatment in this population include psychotherapies such as cognitive behavioural therapy and narrative exposure therapy, medications, and health promotion and psychosocial interventions. Physicians have previously advocated for improving health care for Canada’s refugee population and medical schools are working to incorporate multicultural education into their curricula.
Giving up on everything: a case and review of pervasive refusal syndrome
Authors: Ho Jordan , Charron Brynn
Published: March 2020

We present a case of pervasive refusal syndrome (PRS), in which a 11-year-old female patient refused to eat, drink, interact, or self-care in any way.  The patient was kept on IV nutrition and multiple therapeutic options were tried to no effect. After 18 months, the patient spontaneously recovered with no lasting harm, and her symptoms did not recur.  We further discuss the current state of clinical knowledge on PRS, as well as the form that has appeared amongst children in asylum-seeking families in Sweden.

La colección de Publicidad Gisbert en Filmoteca Española. El proceso de recuperación de un archivo de documentos publicitarios
Authors: Sánchez Galán María Begoña
Published: March 2020

La publicidad es reflejo de los deseos y necesidades de una población, por lo que su estudio permite conocer la evolución económica, histórica y sociológica de los individuos para los que ha sido diseñada. El acceso a los mensajes publicitarios que se han elaborado a lo largo de la historia es clave para poder estudiar la transformación de nuestras sociedades, pero soportes como el cine publicitario histórico son muy difíciles de consultar por su fragilidad material y por la ausencia de proyectos dedicados al análisis y difusión de su contenido. Este artículo resume el proceso por el que un grupo de colaboradores y profesionales de Filmoteca Española abordó la recuperación, catalogación y análisis documental de una colección de documentos procedentes de la agencia Publicidad Gisbert. Para ello se siguió la metodología de gestión y preservación de materiales que se aplica a todos los fondos que llegan a la Institución. El estudio de esta colección dio como resultado la recuperación de películas publicitarias, dispositivas, fotografías y un archivo de material documental elaborado en la agencia entre 1953 y 1976. Estos materiales son una fuente de información primaria de gran interés para el estudio no sólo del cine publicitario, sino también del uso de las pantallas y las salas de cine como soportes de la exhibición publicitaria.

Authors: Nayak Samrudhi , Mishra S.P , Mishra C.S.K
Published: March 2020

The aim of this study is to restore the nutrient status of iron ore mine spoil through suitable organic interventions. This paper reports the effects of different organic manure and bio-fertilizer amendments with inoculation of the earthworm Eisenia fetida in iron mine spoil
on certain chemical parameters, microbial load and soil exoenzyme activities. The mine spoil samples were collected at random from five years old spoil dump and amended with farmyard manure (FYM), poultry manure (PM) and vermimanure (VM) along with biofertilizer in different combinations.
The pH, conductivity, % organic carbon, N, P, K, bacterial and fungal population with activities of soil exoenzymes amylase, cellulase and invertase were studied in organically amended mine spoil. Significant variations (p<0.05) in the chemical and biological parameters were observed between
treatments and days of incubation. Higher values were obtained with PM followed by FYM and VM. Earthworm inoculation enhanced the values of all the chemical parameters except % organic carbon. Bacterial population and exoenzyme activities increased significantly (p<0.05) with earthworm.
PM with biofertilizer was found to be the most suitable combination followed by FYM. Inoculation of Eisenia fetida could facilitate mineralization of organics resulting in higher nutrient availability, higher microbial load and exoenzyme activities required to facilitate spoil reclamation.

Published: March 2020

Hydrated products, such as (hydrated) cement pastes, decomposition through physical-chemical alterations when submitted to high temperatures. One of the main factors that lead to microstructural changes during calcination up to 800ºC, is the dehydration phases of hydrated Portland
cement. The present study sought to characterize crystalline phases occurring before and after calcination to the produced pastes using X-ray diffraction (XRD) analysis. Cement pastes were produced using Portland cement CP V-ARI RS, similar to type II (ASTM C150-07), with water/cement ratio
0.5. After a 28-day curing period, the pastes were calcinated at 800°C for 60 minutes with a 10°C/min heating rate. Afterwards, the newly produced hydraulic binder was cooled abruptly and reactivated through a rehydration process, and underwent analyses on the 7 and 28 day. During
this study it was observed that the originally hydrated products can be rehydrated.
An Economic, Technical and Environmental Feasibility Study for Slurry Injection for Biosolids Management in the Dallas Fort Worth Metroplex
Authors: Panchal Y. , Mohamed I.M. , Pierce Dale , Mounir N. , Abou-Sayed O. , Loloi  , Abou-Sayed
Published: March 2020

In Dallas Fort Worth (DFW), sewage is treated with a combination of anaerobic digestion, effluent filtration and lime stabilization to create biosolids which are then composted, landfilled, or land applied. The current treatment procedure has certain concerns including emissions or
accumulation of odors, pathogens, nutrients, metals, and pharmaceutical products.
 An alternative method, the Slurry Injection technique, enables the digestion of biosolids in the deep earth and can replace the current practice of wastewater treatment or disposal in a much more environmentally
friendly and cost-efficient manner. By completely sequestering methane and CO2 into deep geologic formations which are produced as biosolids breakdown, reduces the greenhouse gas emissions and enables the operator to create greenhouse gas emission offset credits which can be marketed
to offset the operating costs.
 The economic, environmental, and technical aspects of building a new biosolids slurry injection facility in DFW, includes both the surface construction requirements as well as the subsurface strata evaluation for containment assurance. For the subsurface
aspects, a geomechanical and stress analysis is performed on the Atoka formation (near the city of Fort Worth) and it confirms a confining layer above and below the injection zone to keep the waste contained for permanent storage.
Experimental Research on Construction-Waste-Classification Algorithms for a Hyperspectral-Camera System
Authors: Ku Yuedong , Yang Jianhong , Fang Huaiying , Zhuang Jiangteng , Xiao Wen
Published: March 2020

A large proportion of construction waste has a high recovery value, and some of the existing recycling-classification methods rely mainly on physical properties for vibration screening. In order to effectively recover construction waste, an industrial near-infrared hyperspectral camera
is proposed in this paper to distinguish the spectral characteristics of the objects. The testing results were verified using an extreme learning machine, an adaptive-learning multilayer perceptron, and a one-dimensional convolutional neural network classification model. By establishing several
different models to classify and identify the same kinds of experimental materials, the experimental results not only output the correct recognition rate, but also use the recognition efficiency and stability as indices for comprehensive evaluation. The results show that different classification
models have different efficiencies and levels of correctness. Under different analytical conditions, such as when using data from different bands, it is very important to select the appropriate classification model to classify construction waste.
Solid Waste Management Policies in Kenya: The Silence on the Plight of Women and Children

Published: March 2020

Building on available evidence that there are differences of exposure to solid waste among men, women and children, it follows that effective solid waste management (SWM) policies need to recognise such variations, as a prelude to rolling out programmes to address associated socio-economic
and health risks. However, this logical scenario does not seem to be the case in many middle- and low-income countries. In this paper, we use analytical review methodology to examine integrated environmental management and sector specific policies in Nairobi and Mombasa, Kenya's two biggest
cities, to highlight the extent to which existing policies cover the differential challenges of exposure to solid waste and associated health challenges for women and children. We found that apart from one municipal policy and the Kenya Vision 2030 documents respectively, which underscore
the importance of including women and young people in waste management, 16 other policy documents reviewed are generally silent on women and children issues. Beyond the limited focus on women- and children-specific challenges, the general lag in policy implementation and enforcement of regulations
will still hinder the emergence of an effective SWM system out of the best policy frameworks . The preceding discussion underscores both policy and implementation gaps, which need to be filled, if policies will potentially engender SWM practices that will be relevant and effective in protecting
the health of the most vulnerable in urban Africa.

Authors: Uzun Yasemin
Published: March 2020

This research aimed to determine the anxiety levels of students towards Bosnian, their native language, and Turkish, which is a foreign language. With this aim, two separate scales were used in the study to determine speech anxiety levels. The sample of the study is comprised of 49 female students. It is a qualitative research, and the data gathered in this study were evaluated on SPSS 21.0 software package. The findings indicated that the levels of anxiety of students comprising the sample group toward mother tongue were moderate, and their out-of-class speech anxiety level, one of the levels of anxiety toward foreign language, was higher than the mean. There was no significant difference between the levels of anxiety toward mother tongue and the levels of anxiety toward foreign language of the students comprising the sample group. In line with the findings obtained from the application, interviews were conducted with the students on the causes of anxiety. The causes of anxiety students referred to include getting excited, being embarrassed, being badly criticized, fearing that their knowledge is inadequate.
Decentralization of Public Services and the Role of Local Government in Rural Development: Findings From Bangladesh
Authors: Khisa Manila
Published: March 2020

Over the past few decades, decentralizing public services and rendering administrative power to the local government institutions has become a popularly followed strategy to accelerate development in the rural areas. Since its independence till date, Bangladesh has taken quite a number of decentralization initiatives in the areas of health, education, agriculture and small industry promotional activities. This study has adopted secondary data analysis method to examine the degree of rural development made through decentralized public service delivery by the local government institutions of Bangladesh. The study suggests that, despite some improvement, the local governments in Bangladesh have not managed to bring significant changes at the rural level due to political supremacy, administrative and financial incapacity. The study concluded with identifying the changes that are necessary in the areas of resource accumulation and management, financial and administrative decision making system, political and bureaucratic capacity.

Published: March 2020

Many descriptions of paralarval and juvenile cephalopods are poor. By using DNA barcoding, a global bioidentification system for animals, along with morphological investigation, we can confirm species identifications. We have a better chance of eliminating misidentifications and, therefore,
documenting the correct abundance and distribution of cephalopods within an area by combining morphological and molecular evidence. The central objectives of this study are to: (1) compare morphological vs molecular identification of cephalopods and (2) determine the occurrence of cephalopods
within the deep scattering layer (DSL) within warm core eddies. The specimens reported here were collected between 2014 and 2016 during three transatlantic cruises from Galway, Ireland to St John's, Newfoundland, with a focus on assemblages in warm-core mesoscale eddies on the western part
of the transect. Samples were collected from the DSL at multiple stations across mesoscale eddies. In total, 301 cephalopods belonging to 29 species were collected. Not only does our study increase the knowledge of abundance and diversity of pelagic cephalopods in this area, but it also provides
sequences for species for which no comparative sequences were previously available. By examining the match/mismatch between morphological and molecular identifications, we highlight a need for revisions in some taxonomic groupings such as the family Cranchiidae.

Published: March 2020

Aim of study: Soils contaminated by heavy metals, such as cadmium, may reduce plant development. Exogenous application of plant growth regulators (PGR), are used for optimizing the crops production in stressful environments. The aim of this study was to evaluate the effects of Cd concentrations on the development of soybean seedlings under exogenous application of a commercial PGR.Area of study: Presidente Prudente, São Paulo, Brazil.Material and methods: Soybean seeds were pre-treated in distilled water (control treatment) and in solution with plant growth regulator (PGR treatment) and then germinated with distillated water. The germinated seeds were transferred to different levels of Cd (0, 100, 500 and 900 mg of Cd).Main results: Cd exposure at increasing concentrations, decreased root development, (area, length and volume of roots) and activity of enzymatic antioxidants (SOD, CAT and APX) and enhanced MDA. These responses were accentuated by the PGR exposition. The root morphology and activity of antioxidant enzymes presented "hormesis" responses until 500 mg L-1 of Cd, and the proline content may have played a fundamental role in the maintenance of metabolic activities and biomass.Research highlights: The results indicate that the use of PGR intensified the toxicity responses caused by exposure to increased Cd level. In addition, stress indicators such as MDA content and antioxidant activity in different organs (root and shoot) of soybean seedlings, responded differently according with the use of PGR under exposure of Cd.

The specific protease activity in juice from ginger ripened after harvesting was higher than that of ginger that was not ripened after harvesting. Sodium dodecyl sulphate-polyacrylamide gel electrophoresis indicated that the ginger rhizome juice displaying high specific protease activity contained a 30 kDa protein. This juice was also observed to have milk gel-forming ability.
Experimental Investigation of the Micro-hardness of EN-31 Die Steel in a Powder-Mixed Near-Dry Electric Discharge Machining Method
Authors: Sundriyal Sanjay , Vipin  , Walia Ravinderjit Singh
Published: March 2020

The Powder-Mixed Near-Dry Electric Discharge Machining (PMND-EDM) methodology has proven to be efficient in terms of machining rate, surface morphology, and environmental friendliness, unlike traditional EDM. In this study, the presence of a conductive metallic powder (zinc) in the dielectric medium was responsible for changing the topography of the workpiece (EN-31) and resulted in a higher micro-hardness value of the machined component. In this research, an approach has been made to optimize the significant process parameters by using a Taguchi L9 orthogonal array (OA) to obtain machined components with higher values of micro-hardness, which was measured in terms of Vickers hardness HV. The selected process parameters were tool diameter, mist flow rate, metallic powder concentration, and dielectric mist pressure. By introducing foreign particles (metallic powder), the topography of the machined products has been improved, and the micro-hardness value was found to be enhanced. The confirmation experiment was performed for optimal process parameter settings, and the enhanced microhardness value was found to be 506.63 HV in the machined EN-31 die steel.

Published: March 2020

I föreliggande artikel studeras nyanlända elevers upplevelser av att vara elever på Språkintroduktion. Programmet är ett av fem introduktionsprogram i gymnasieskolan och tar emot nyanlända elever från 16 till 19 år. Eleverna placeras på Språkintroduktion eftersom de nyligen har kommit till Sverige och för att de ännu inte uppnått tillräckliga kunskaper i det svenska språket. I denna intervjustudie bidrar Homi Bhabhas teori om mellanrummet till en förståelse för hur erfarenheter av Språkintroduktion kan upplevas. Resultatet visar att elevgrupperna på Språkintroduktion är heterogena eftersom eleverna har olika erfarenheter av skola och arbete. Tre teman blir synliga i resultatet: elever med andra kunskaper och erfarenheter, elevidentiteter som särskilt framträder och det svenska språket som barriär. Resultaten visar att förvärvandet av det svenska språket för varje elev blir ett mål att nå samtidigt som det utgör ett hinder. Språket blir viktigt eftersom eleverna är beroende av det för att lyckas såväl i skolan som i samhällslivet. Likaså blir synliggörandet av elevers tidigare erfarenheter och kunskaper betydelsefullt eftersom det kan komma att påverka deras identitetsuppfattning.

Newly arrived upper secondary school students – Student identities and language barriers

AbsractThis study investigates newly arrived students’ experiences of being students at Language Introduction in Sweden. The program is one of five introductory programs in Swedish upper secondary school and admits newly arrived students from the ages of 16 to 19 years old. Students are placed at Language introduction because they have recently arrived in Sweden and since they have not yet gained enough knowledge of the Swedish language. In this interview study, Homi Bhabha’s theory of the third space contributes to an understanding of how experiences from Language introduction can be perceived. The results show that student groups at Language introduction are heterogeneous as students have diverse experiences of school and work. Three themes appear in the results: students with other kinds of knowledge and experiences, student identities in transformation, the Swedish language as an obstacle and as goal. The results show that the acquisition of the Swedish language becomes to each student a goal to reach and at the same time a hindrance. The language becomes important because the students depend on it in order to be successful in school as well as in life in society. Likewise, making the students’ past experiences and knowledge visible, becomes important as it may affect their perception of identity.

Die (Register-)Publizität der Gesellschaft bürgerlichen Rechts
Authors: Michels André
Published: March 2020

As a basic form of civil partnerships, the GbR is extremely changeable and can disappear from existence just as quickly as it was founded. In contrast to other partnerships, the GbR is not primarily registered. This lack of register publicity has been of particular concern not only to the literature and jurisdiction, but sometimes also to the legislator, especially since the recognition of the legal capacity of all “Außen-GbRs” [outside companies].

This work comprehensively addresses the question of whether and to what extent the lack of register publicity of the GbR under the applicable law can lead to difficulties and draws conclusions for legislative measures. In addition to a systematic comparison and evaluation of the arguments, as well as ideas for solutions that have been discussed in detail in literature so far, problems and (technical) aspects of a registration that have not yet been taken into consideration are worked out and subjected to a critical examination.

Published: March 2020

Studies about differential equations provide many mathematical instruments that aid the insight of many practical problems. The goal of this paper is to obtain a differential equation that describes an Electrical Engineering problem, then to define the solution of this equation using analytical methods and to compare theoretical and experimental results. Firstly, the second order differential equation with constant coefficients and the analytical method to obtain the respective solution will be studied; later this solution will be applied in the problem of an LRC electrical circuit with simple mesh with an inductor (L), a resistor (R), a capacitor (C) and an electromotive source. The goal is to solve the differential equation to define the charge, in function of the time, between the capacitor and the inductor. The solution is obtained from the homogeneous solution (admitting a solution in the exponential form) and the particular solution (using the undetermined coefficients method, due to function form). Initial conditions for the initial charge and the initial current can be used, with the analytical methods, to find the particular solution of the problem.

For a long time the concepts of economic growth and entrepreneurship were understood as essential for the development of a country. Schumpeter introduced the concept of entrepreneurship, seeking to reinforce the association between entrepreneur and innovation as a proportioning element of economic development. According to Schumpeter (1982), entrepreneur is the person who can convert an idea or invention into a successful innovation. The current developmental framework of society and the constant economic, social and cultural transformations contribute significantly to the changes in the ways of thinking and acting of contemporary man.

The Institutional Development Project entitled “Interactive Dynamic Space: An Alternative to Traditional Teaching” was intended to create the model interior design project for a classroom that encourages the development of different activities, as well as having layout flexibility, which covers a range of space arrangements, and could be implemented in every education center of Universidade Federal de Santa Maria. The demand for this project came from the Vice Rector of this institution, professor Luciano Schuch, who intends, from the elaborated project, to support the execution of one of these rooms per education center of the University. The goal, therefore, was to create a model project that can be adapted to each situation of each teaching unit. As a basis for the development of this project it was used one of the rooms of the new buildings of Cachoeira do Sul Campus, which will receive, as a pilot, the first project executed of these dynamic and interactive rooms. The architectural project and the budget were finalized in 2018, the ideal financial conditions for bidding and execution are currently awaited.

The windsock is a meteorological instrument that indicates wind direction. This instrument is critical in sea travel and aviation and this sensor can prevent accidents in emergency situations such as storms caused by a particular wind direction.hus, in this work it is proposed to develop an electronic windsock using a rotary encoder module and infrared LEDS. For the development of the Wind Direction Sensor project an Arduino microcontroller and c ++ language were used. The engineered hybrid system converts the rotations into an electrical signal. These signals were associated with east, west, north and south orientations. The projected sensor presented a lower probability of error in the wind direction information when compared to the windsock that employs 5mm Infrared LED.

In this work a test equipment called RBS was developed to monitor the operation of a washing machine power board. The RBS identify  the main defects of Brastemp and Consul washing machines. The developed RBS equipment verifies that the machine's power plate is sending electrical signal to its peripherals such as valve 1, the drainage pump, the clockwise motor and the counterclockwise motor. The operation of each machine peripherals is represented by an LED on the circuit. The defect in the board can be verified by the LED that does not light up in the circuit. Thus, through RBS it is possible to save time in identifying washing machine problems and to obtain a reliable test system after repairing them. Additionally, it is important to note that the cost of the equipment developed is approximately R$ 26.00, while commercial self-test systems cost approximately two hundred reais.

The presence of weed species in soybean crops is a concern for farmers. Knowing these species is of great importance, as they cause serious damage to crops due to competition for nutrients, water, light and physical space with soy. This work aimed to survey weeds in pivot irrigated soybean crops in Cachoeira do Sul municipality, Capané district, in the experimental area of the Rio Grandense do Arroz Institute (IRGA). The evaluations were performed by applying the 0.25 m2 square method, launched at random sixty times. Weeds in the sampled areas were removed from the soil, species identified and quantified. Evaluations were performed after three applications of glyphosate herbicide. Even after glyphosate applications, seven species were identified, representing the families Asteraceae, Poaceae, Malvaceae, Euphorbiaceae and Rubiaceae. This survey enables the planning of preventive strategies for the sustainable control of weeds in the field, reducing production costs and the impact on the environment.

The objective of this work was to evaluate the development, yield components and grain yield of different soybean cultivars with and without supplemental irrigation, in the 2018/19 crop, in coxilha soil in Cachoeira do Sul - RS. The experiment was conducted at the UERGS Agronomic Experimental Station. The experimental design was in bands in factorial scheme (3x2), with four replications. The treatments consisted of: factor “A” three soybean cultivars: Nidera 6909 IPRO (NS 6909), Nidera 5909 RG (NA 5909) and Nidera 4823 RR (NS 4823); fFactor “B” two water regimes: irrigated and non-irrigated. Regular rainfall distributions were observed throughout the soybean cycle and volumes totaled 655 mm higher than the cumulative ETc of 413.19 mm. Supplementary irrigation of 134.5 mm was required, which promoted an increase of 18% in IAF, 5.2% in PMG and 7.5% in grain yield, which was 4492.6 kg ha-1 for the water regime. 4158.2 kg ha-1 for the non-irrigated water regime. The cultivars NA 5909 and NS 4823 presented average grain yields of 4659.05 kg ha-1 and the cultivar NS 6909 of 3658.2 kg ha-1

The objective of this study was to analyze the development of diferente soybean cultivars in two sowing dates in Cachoeira do Sul – RS. A field experimente was carried out at UERGS agronomic station, whose soil is classified as Red Argisol. The experimental desing used was in factorial desing (2x3). Factor “A” constitued two sowing dates (11/21/2018; 01/11/2019) and fator “B” constitued three soybean cultivars (NS4823; NA5909; NS6909). Phenological evaluations were performed weekly. Data were organized into 2 subperiods: emergence at full bloom (EM-R1) and full bloom at physiological maturity (R1-R8). In the subperiod EM-R1, the cultivars NS6909 and NA5909 did not present statistical differences among themselves, but differed from the cultivar NS4823, with duration of 49, 48 and 38 days, respectively. In the R1-R8 subperiod, no statistical differences were observed for cultivars NS6909 and NS4823, which differed from cultivar NA5909, with duration of 66, 67 and 71 days, respectively. Late sowing resulted in a shortening of 15 days in the total cycle, which may reflect yield reductions.
