The main objective of this work was to quantify and evaluate the occurrence of corn grain losses due to the different speeds of the harvesting machine in the second harvest, considering that, in the state of Mato Grosso, corn cultivation, mainly in the off-season, has been gaining space every year due to the increase in both the quality and the quantity of grains planted and harvested in the state. The frame was made in relation to the size of the platform with 0.37 m in length, the frame was superimposed on the straw to collect the grains lost by the harvester. The experiment was carried out at speeds of 3.5; 4,5; 5.0; 5.5 and 6 km.h-1 with rotation of 540 per minute in the cylinder and concave in the opening position No. 05 corresponding to 50 mm of standardized opening for all speeds, where it was possible to observe that there were no significant losses of corn kernels with the speed of the harvester 3.5 km.h-1. The variation between the losses is 30.2 kg per hectare of whole corn grains, between the speeds of harvest tested. It was concluded that the speed of the harvester of 3.5 km.h-1 has lower losses of corn kernels when compared to the other speeds experienced, noting that this loss was lower, acceptable for maize.

Estimates for the 2018/2019 grain crop indicate production in the order of 238.5 million tons, an increase of 4.7% compared to the 2017/2018 harvest. This production, although satisfactory, could still be greater, were it not for the problems faced with the logistics of grain disposal where billions are lost due to the limited investment in infrastructure. The objective of this work is to establish a percentage loss index, as well as to assess these quantitative losses during bulk grain transportation of corn. The research was developed through a partnership between the National Supply Company (CONAB) and the NTA (Nucleus of Storage Technology), at the Federal University of Mato Grosso. It was established the evaluation of losses related to grain transportation in the main waterways, being bulk corn in BR 163/364 in the State of Mato Grosso. After the choice of the highways evaluated, we carried out research on the data of romaneios in the transportation of corn in bulk. The obtained data, through the romaneios, provided weight of origin, weight of destination, place of origin and place of destination, in this way, by difference was obtained the quantity of grains lost in the transport and the mileage traveled in each route. By means of these data it was possible to obtain three indices of losses, one in Kg/Km (kilogram per kilometer wheeled), another one in Kg/t (kilograms per tons transported), and also determined an index of loss in percentage of grains transported. With the indication of the indices it was possible to evaluate the losses. The Bitrem truck (7 axles) was used as the basis for calculating the losses, since during the interviews this was the type that had the most occurrences in BRs evaluated, with 39%. Based on the questionnaire, the load weight of 38,000 kg was therefore adopted. For the study of corn grain losses in road transport, 39,642 data were analyzed for routs, with 24,902,808.50 km rotated, mean of 628,19 km away by route. The amount of corn grain transported was 1,852,437,042 kg. The total losses were 1,808,951 kg, averaging 45.63 kg of loss per trip. The loss per km was on average of 0.072 kg. Transport of corn grains between Nova Ubiratã and Rondonópolis presented the highest frequency of trips (8629 trips), however the losses were 37,710 kg of grains or approximately 628 bags of corn (60 Kg). The index of percentage loss for maize (0.1025%). This percentage is lower than the adopted one that is of 0.25%, nevertheless, represent considerable losses for the economy. Based on the data obtained in the present study, it can be stated that it is possible to adopt percentage loss rates of less than 0.25% in contracts. It is recommended to adopt the percentage rates of grain loss in road transport of 0.10% for maize.

The aim of this study was to identify the relation between the evapotranspirometer demand and the supply of water from local rainfall, evaluating the possibility of using water excess for irrigation of Green Roofs in the State of Mato Grosso, in Brazil. The study was done using a series of historical data provided by the National Institute of Meteorology (INMET - Instituto Nacional de Meteorologia) which has official climatological stations in 12 cities and regions of the State. The evapotranspiration values were obtained by the Penman-Monteith method and by the Climatic Water Balance (CWB) by the Thornthwaite and Mather method using Available Water Capacity (AWC) of 12mm. With the CWB the excess and deficit were calculated, which were used for the estimative of the volume and area of a reservoir as a function of a collector area of a roof of 100m² and the volume of supplementary water for irrigation. With the obtained results, it was found that in most investigated regions of the State the use of green roofs is not compromised by the water deficiency. On the other hand, the use of a reservoir to accumulate the rain water excess may be impractical, because it requires a considerable area for installation and also because of the high cost of the land.

The paper presents the results of a study on chemical composition of ashes from three types of waste biomass in terms of fertilizer usefulness. Waste from the process of corn grain drying, including corn cobs, corn grains and corn husk and their mixtures in the ratio 4:1 (v/v) were examined. The study proved that corn grain was the material with the highest concentration of macroelements among those studied (P—21,452 ppm, K—25,970 ppm, S—5911 ppm) and the mixture of corn cobs with corn grains (Ca—81,521 ppm). When microelements were considered, the highest concentration was recorded for corn cobs (Cu—207 ppm, Mn—844 ppm, Zn—857 ppm) and corn husk (Fe—15,100 ppm). The analysis of toxic elements in the ashes of the biomass studied showed their highest concentration in corn husk ash (Ni—494 ppm, Cr—301 ppm, Pb—42.7 ppm, As—4.62 ppm). The analysis showed that regardless of the type of biomass studied, all ashes were strongly enriched (in relation to the average soil content) with phosphorus and corn husk ash with calcium in particular. A slight enrichment in copper and lead was recorded for all ashes, and moderate or low for the other elements. It was found that the examined ashes from biomass, which is a residue from the drying of maize grain, have a high fertilizer usefulness.

Five black-tailed marmoset Callithrix (Mico) melanura (Primates - Callitrichidae) individuals were monitored by radiotelemetry as part of a project on translocated wildlife affected by flooding the Manso River reservoir in the state of Mato Grosso, western Brazil (14° 52' S and 55° 48' W). The animals were monitored for eight months from October 2000 through August 2001. Only one death was recorded among the translocated animals. Two pairs established their home ranges in the new area, after some exploratory behavior. The new home range sizes varied from 0.72 to 4.27 km². The home ranges of male and female overlapped in the case of both pairs by 0.59 to 2.30 km². Trips were always made in pairs and not individually. The results indicate the feasibility of a successful translocation program for this species, as long as the animals are translocated to a similar habitat nearby.

Contemporary document research involves the need to use the latest technologies and analytical techniques that provide the most complete possible knowledge of contemporary issues and methods of document research. Documents are used to record legal actions and events of legal significance. By their essence, they are therefore closely related to the sphere of rights and obligations of a specific person or institution. Crimes against documents pose a threat to the proper functioning of the state and thus the development of every enterprise. They affect, directly or indirectly, the misallocation of financial resources at the disposal of an enterprise. Forging documents may be aimed at obtaining unauthorized access to specific sources of financing, influencing key management decisions made in the company, or, finally, concealing inconvenient facts. On the other hand, the social harm suffered as a result of forging documents of evidence significance in tax matters may be enormous. For this reason, it is necessary to deepen the knowledge of the dynamics characterizing document forgery in the sphere of economic activity in order for the state to activate mechanisms able to prevent this type of crime. The article describes the issues of selected tax frauds in Italy with the use of accounting documents.

Very soon after the establishment of the State (and as an important part of its constitutional structure) the office of State Comptroller, responsible to the Knesset alone and independent of the Government, was established under statute—the State Comptroller Law of 1949. After undergoing a number of amendments, the Law was eventually replaced in 1958 by a Consolidated Version but without any substantive change being made in the functions and powers of the Comptroller, a fact which goes far to demonstrate the proven worth of the office.Briefly, the functions of the Comptroller are to carry out “inspection of the finances and the management of the finances and the property and administration of the State and of the bodies subject to the inspection of the Comptroller, and to perform the other functions assigned to the Comptroller by this Law”.The bodies subject to inspection include, in addition to every government department, state enterprises and institutions and local authorities, persons or bodies holding, otherwise than under contract, or managing or controlling any state property or funds in the management of which the Government has a share or which are made subject to inspection by the Knesset or by agreement with the Government.

The present work had the objective of quantifying corn grain losses in road transportation along a section of highway BR 163 in the state of Mato Grosso. The survey was done in July and August of 2016 in the section between the Imigrantes Highway, within the city of Cuiabá - MT, and the municipality of Nova Mutum – MT. This stretch is considered to be the one with the highest flow of grain loads in the state of Mato Grosso. Twenty one collect points were established along the stretch, with a distance of 10 km from one point to the other, at each collect point 3 areas of 1 m² were delimited with the aid of a fixed frame of wood with the same area, in a distance of 1.3 m from the highway margin, in the north-south direction, which is the direction of the grain flow. The samples were placed in identified plastic bags and taken to the laboratory for separation and weighing. The points of the biggest grain losses were points 06 and 12 of the section, where it was verified pavement in poor quality with much road surfacing, and the points of lower losses were collected in the top quality asphalt range.

Starting out from the conception that agrarian space is a subspace created by rural activities within a totality which includes the city with its multiple varied interactions, the present study focuses on the agrarian space of the state of Rio de Janeiro as affected by the urban-industrial economy. It identifies is as a traditional agrarian space in which the effects of urban growth are making themselves felt in spatially differentiated and structurally contradictory forms. The internal disparities are seen in the context of the social, economic and political formation of the state, from which emerge, as agents of considerable importance and on different scales, the coffee economy which conditioned the settlement and appropriation of the territory and, on the other hand, the functions of Rio de Janeiro as a port, a centre of political power and a national metropolis. With a background of dairy-farming, replacing coffee-growing in almost the whole of the state, and single-crop sugarcane cultivation in the Baixada Campista, the agrarian space of the state of Rio de Janeiro illustrates overall limitations and problems of the state's economy, within a framework of immobility or feeble growth. This formally stationary framework has been passing through changes in organization and structure which have reflected, during the past thirty years, different ways in which the state of Rio de Janeiro has shared in the overall process of the country's development reflecting, at one and the same time, capitalist expansion in the rural sector and its articulations with various political actions aimed directly or not at that sector. As a result of their extent and their social and economic implications, a number of important variables are referred to in this study as indicators of changes. They are variables referring to land use, recorded in the Censures from 1950 to 1980, and others characteristic of the modes of production, brought up in the course of field surveys. The expansion and modernization of cattle-raising in specifically defined areas in the state, the widespread fall-off in permanent cultivation and the increase in temporarily cultiva>;ted areas reflect new options for producers in connection with less expensive and more profitable activities. The strengthening of sugarcane cultivation, the extension of silviculture, especially since 1970, and the resurgence of coffee-growing display the effects of agricultural policies based on subsidized credit. Of the various forms of innovatibn in the state rural area which are focused on in this study, none shows the direct interference of Rio de Janeiro as a consumer market. Not even cattle-raising practised on the enterprise model on the periphery closest to the city is fundamentally directed towards Rio's consumer market, except for dairy production of the beef cattle produced there, only 10% or so are earmarked for this market. In the coastal lowlands of the Lake Region, specialization in the production of cows and bulls for breeding purposes, which is being consolidated in conjunction with the pastoral areas of Minas Gerais, Espirito Santo, Goias and Mato Grosso, offers the most obvious prood of the alienation of the producing area from the immediate market of Greater Rio. The geographical distribution and configuration of the dynamic segments and the stagnant pockets in the state point to another feature of its agrarian framework. The great motor-way axes which bring Rio de Janeiro into contact with the other metropolises in the Southeast or with the Northeast via the coastal highway are today the great lines along which the modernization of rural activities and new social relations of production are being diffused, so creating a new agrarian framework which has little or nothing to do with the previous one or with the great metropolitan market. From the above-mentioned frame of reference, it is quite clear that the agrarian space of the state of Rio de Janeiro is being transformed under the action of forces superior to market ones, forces which transcend the system of internal relations of the state itself, embodying the process of capital enrichment of the rural areas and a new spatial structuring linked to the projection of Rio de Janeiro on a national scale, more than to its local or regional action.
