title: A political economic view about the Brazil's minimum price guarantee policy

description: Abstract This paper aims to analyze the evolution of the agricultural minimum price guarantee policy (PGPM in Portuguese) in Brazil from 1987 through 2014 (a time period when profound changes took place in both formulation and grants of the mentioned policy) under the political economy point of view. The latter considers, among other issues, the role of interest groups, macro policy system (including the decision arenas), policy subsystems and policy networks. All of them help to understand the three major changes in PGPM during the last 20 years: (1st) the split between support programs for family farming and for non-family farming; (2nd) the less subventionary features of the new PGPM instruments that meet the non-family agriculture; and (3rd) the donor character of programs that cater to family farming.

title: Advancement of research involving Aspergillus niger and sugarcane bagasse as a source of carbon for the production of cellulases: A bibliometric analysis

description: ABSTRACT A variety of studies have been realized with the objective of producing celulases with low cost to be used in the production of second generation alcohol (2G) from lignocellulosic residues. Among them, the use of sugarcane bagasse as carbon source for the growth of microorganisms is highlighted. Based on this, this article aimed to carry out a bibliometric review on the use of Aspergillus niger using sugarcane bagasse as a carbon source, aiming the production of cellulase, through the study of scientific and technological advances on the themes. To perform the review, we used the Web of Science database, inserting four keywords: "Aspergillus niger", "cellulase", "cane" and "submerged" between the years of 1945 and 2018. From this search, was possible to identify the most important authors, periodicals and research groups in this subject. It was identified an increase in the number of publications over the years by several countries, showing interest in the production of lower cost cellulases for 2G alcohol generation. Brazil was the country with the largest number of publications on the subject, due to the great capacity of planting sugarcane and production of alcohol. By analyzing the correlation networks of the authors it was verified the existence of a relation of the research groups in Brazil, between the cities of Campinas, São Paulo and Curitiba and another association in Denmark, between the cities of Lyngby and Copenhagen.

title: Classification of mortars with incorporation of phase change materials based on their physical, mechanical and thermal properties

description: ABSTRACT Currently, there are several mortars available for application in the construction industry. These mortars can be based on different binders, have different physical and mechanical properties and even other specific properties. However, the correct selection of a mortar becomes increasingly difficult. Thus, comes up the need to classify different mortars based on a specific criteria and a single procedure. In this way, it will be possible to identify the most appropriate mortars according to their function. In this research, a materials ranking procedure developed by Czarnecki and Lukowski is applied, based on an usability function. The ranking procedure transforms experimental results of properties into one numerical value. The products can be classified according to their individual properties or even an optimized combination of different properties. Thus, the main purpose of this study was the ranking of mortars based in different binders with incorporation of phase change materials. Hydraulic lime, gypsum and cement were the binders studied. For each binder, three different mortars were developed, reference mortars (0% PCM), mortars with incorporation of 40% of PCM and mortars with incorporation of 40% of PCM and 1% of fibers. Based on the results it was possible to conclude that the incorporation of PCM in mortars changes their global performance.

title: Substrate and quality mangosteen seedlings

description: Abstract An obstacle to the production of mangosteen seedlings (Garcinia mangostana L.) is the long nursery time of approximately two years. Among other factors, the identification of a suitable substrate for seedling production from this species is a preponderant factor to reduce nursery time. This study aimed to evaluate the growth of seminal mangosteen seedlings grown in four different substrate compositions. Growth rate was determined using the following variables: stem diameter, plant height, stem dry mass, leaf dry mass, shoot dry mass, root dry mass, total dry mass and Dickson Quality Index (DQI). The substrate S1 (sphagnum turf and vermiculite) was superior to substrates S2 (pinus bark and vermiculite), S3 (pinus bark and coconut fiber) and S4 (soil) in all evaluated parameters. The principal component analysis separated the treatments into three response groups, in which S1 exerted the greatest influence on the growth variables, concluding that this one of the substrates tested was the most adequate for the formation of mangosteen seedlings.

title: A Mathematical Model for Simulating Meteor Showers

description: ABSTRACT This paper presents a mathematical model to simulate the trajectory of a meteor as seen by a single observer located anywhere on Earth. Our strategy is to define a new coordinate system, called Radiant Coordinate System, which is centered on the observer and has its z-axis aligned with the radiant. This new coordinate system allows us to describe the meteors’ path by applying a reduced number of equations in a simple solution. We also present a computational implementation of this model, which is developed as a new plug-in of Stellarium, a free and open-source planetarium software. Moreover, we show that our model can be used to simulate both meteor showers and sporadic meteors. In particular, meteor showers are simulated using data provided by real catalogs.

title: Identifying agriculture land acquisitions for alleviating future food security concerns

description: Abstract The total available land for food, fuel, or forests is finite, while land demand is increasing and expected to increase further in the coming decades; resulting in deterioration of food security. Therefore, the corporate world adopted a solution of acquiring international agricultural land. Consequently, the global demand for land has progressively risen, but the question requiring decision support is - which lands to acquire for food production to ensure future food security? Food Science and Technology has vital pivotal roles to play in improving this situation, as food science is inherently multidisciplinary and motivated by the use of new technologies. In this paper, we endeavour to address this multidisciplinary food science question, by considering 16 Middle East North Africa (MENA) region countries having extreme economic diversity and enormous variation in adaptive capacity. Our study parameters consist of CO2 fertilization, water scarcity and meta-parameter of climate change vulnerability. Using logical inference and principal of separate modifiability, major food security concerns were identified for 2030.

title: Analysis of selective potato varieties and their functional assessment

description: Abstract The number of attributes, related to the selection of potato varieties, was evaluated with reference to their potential in chip processing. Five commercial varieties of potato were analyzed regarding their physico-chemical, functional, and processing aspects. In general, Lady Rosetta subsequently, Chipsona were the most noticeable potato varieties considering their physical attributes. A significant correlation (R = 0.925) was estimated amongst geometric mean diameter and surface area. Maximum dry matter and starch contents were observed in Lady Rosetta followed by Chipsona. Desiree showed higher fat, sugar and mineral contents than all other selected potato cultivars. Promising correlation (R= 0.952) was estimated among total minerals and ash contents. Functional traits were recorded maximum in Desiree followed by Lady Rosetta. A significant correlation (R = 0.907) was described between total phenolic contents and radical scavenging activity. Lady Rosetta proved to be the most preferred potato variety considering post processing parameters followed by Chipsona.

title: State biomarkers for Machado Joseph disease: Validation, feasibility and responsiveness to change

description: Abstract Machado-Joseph disease (SCA3/MJD) is the most common spinocerebellar ataxia worldwide, and particularly so in Southern Brazil. Due to an expanded polyglutamine at ataxin-3, SCA3/MJD presents a relentless course with no current disease modifying treatment. Clinical scales used to measure SCA3/MJD progression present moderate effect sizes, a major drawback for their use as main outcomes in clinical trials, given the rarity and slow progression of the disease. This limitation might be overcome by finding good surrogate markers. We present here a review of studies on peripheral and neurophysiological markers in SCA3/MJD that can be candidates for state biomarkers. Data on markers already studied were summarized, giving emphasis on validation against clinical scale, and responsiveness to change. While some biological fluid compounds and neurophysiological parameters showed poor responsiveness, others seemed to be good candidates. Some potential candidates that are waiting for responsiveness studies were serum levels of neuron specific enolase, vestibulo-ocular reflex and video-oculography. Candidates evaluated by RNA and microRNA expression levels need further studies to improve their measurements. Data on peripheral levels of Beclin-1 and DNAJB1 are promising but still incipient. We conclude that several potential candidates should follow onto validating studies for surrogate state biomarkers of SCA3/MJD.

title: Incorporation of nitrogen and phosphorus in the leaves of Typha domingensis Pers. macrophyte during treat dairy cattle wastewater in constructed wetlands

description: ABSTRACT The objective of this study was to evaluate the performance of macrophyte Typha domingensis Pers. in different development stages in the nitrogen and phosphorus removal from a horizontal flow constructed wetland (WCH) applied for dairy cattle wastewater treatment. In this way, growth, nitrogen and phosphorus levels in the leaf tissue of macrophytes were monitored during a 120-day growth period. Typha domingensis Pers. macrophyte was responsible for a mean removal of 5.12 and 3.16% of the applied loads in the WCH, for nitrogen and phosphorus, respectively. The higher nutriens removal rates (30.2 and 6.4 g P kg-1) were identified when the higher tissue growth rates occurred (24.17 cm week-1).

title: Critical analysis by comparison between water quality models applied to polluted rivers: Contributions to health, water and sanitation

description: ABSTRACT The focus of this article is to analyze the presence of organic matter in sewage from BOD-DO models. The model relates to the pollution of a water body by organic matter and the decrease in dissolved oxygen levels caused by the respiration of microorganisms involved in sewage purification. It is highlighted the modeling of different types of pollutant loading release, presenting four types of them, and the effects on the natural water bodies’ self-purification, from two patterns of transport provided by the receiving body; first for a smaller flow and then there is a flow increase. This work also discusses how mathematical models can intervene effectively in the discharge of sewage after treatment and if these can contribute to public health, sanitation and improved conservation of water resources.

title: Performance and carcass characteristics of broilers fed whole corn germ

description: ABSTRACT The objective of this study was to evaluate the effect of including whole corn germ (WCG) on the performance; diet metabolizability; yields of carcass, cuts, and offal; and quality of meat of broilers. A total of 648 chicks were assigned to six treatments in a completely randomized design with six replicates, with 18 birds in each. Treatments consisted of a corn- and soybean meal-based control diet (0 g kg−1 WCG) and five test diets including WCG at the levels of 40, 80, 120, 160, and 200 g kg−1. Birds and diets were weighed at each seven days to determine feed intake (FI), body weight gain (BWG), and feed conversion ratio (FCR). The partial collection methodology was employed to determine the apparent metabolizable energy (AME), nitrogen-corrected AME (AMEn), and the apparent metabolizability coefficients of gross energy (AMCGE), dry matter (AMCDM), crude protein (AMCCP), and ether extract (AMCEE) of the diets. In the evaluation of meat quality, we analyzed the pH, cooking losses, shear force, water-holding capacity, color, and peroxide index of the meat. There was a difference for BWG and FCR in the total rearing period (1 to 42 days), for which optimum BWG was estimated as 2921 g/bird, with 118 g kg−1 inclusion of WCG. There was no difference for the AME, AMEn, and AMCCP of the diets, although AMCGE, AMCDM, and AMCEE declined as WCG was included. The increasing levels of WCG did not influence the yields of carcass and cuts or the meat quality. There was an increase in the yield of gizzard and proventriculus. Whole corn germ can be used at low levels in the diet of broilers without compromising their productive rates.

title: Quantification of floral abnormalities in a population generated from sexual polymorphism aiming at recurrent selection in papaya

description: ABSTRACT The aim of this study was to estimate the percentage of deformed fruits (carpelloid, pentandric, and bananoid), summer sterility, repeatability coefficients, and correlations among the variables for floral abnormalities; and select genotypes withthe lowest incidence of deformed fruits and summer sterility. In theexperiment, which involved 254 plants, traits were evaluated using the digital-phenotypic method and the obtained images were processed and analysed using ImageJ v1.48 software with the Cell Counter plugin. Summer sterility had the highest percentage of occurrence in the evaluated periods. Based on the quantificationof total abnormalities, the 30 genotypes with the lowest incidence offloral abnormalities were selected. Summer sterility is the main problem of the papaya crop in terms of floral abnormalities. The non-significant correlations between the traits: NDF/TNF+NFN (number of deformed fruits/number of fruits + number of fruitless nodes) and NFS/TNF+NFN (number of fruitless nodes/number of fruits + number of fruitless nodes); NDF/TNF+NFN and NFN/SUM(number of fruitless nodes/sum of abnormalities); andNFS/TNF+NFN and NDF/SUM (number of deformed fruits/sum of abnormalities) indicate that the variables are independent of each other. Of the 254 evaluated progenies, at least 30 were identified as having potential for selection, with lower occurrence of total floral abnormalities.
