1. EXTRACTION CAPACITY OF GRASSES GROWN IN CONSTRUCTED WETLAND SYSTEMS USING DIFFERENT ARRANGEMENTS AND SUBSTRATES
ABSTRACT Constructed wetland systems have been used to treat different wastewater; among their essential components are the cultivated plant species and type of substrate used to fill them. The choice of plant species and type of substrate are important for the good system performance in wastewater treatment. This study aimed to evaluate the extraction capac

2. INFLUENCE OF SUBSTRATE AND SPECIES ARRANGEMENT OF CULTIVATED GRASSES ON THE EFFICIENCY OF HORIZONTAL SUBSURFACE FLOW CONSTRUCTED WETLANDS
ABSTRACT We aimed to evaluate the efficiency of six different horizontal subsurface flow constructed wetlands (HSSF-CWs), with different substrates (gravel and crushed PET bottles), which also varied in relation to the presence and arrangement of plant species (elephant grass and Tifton 85 bermudagrass) in the removal of pollutants from a bulk milk cooling t

3. Incidence of aflatoxin M1 in fresh milk from small farms
Abstract The objective of this work was to determine aflatoxin M1 in fresh milk from fifty-two small farms in the city of Concórdia - SC, Brazil. Samples from the cooling tanks of each property were collected from November 2014 to January 2015. The QuEChERS method was used for the extraction of aflatoxin M1, and quantification was performed in UHPLC-FL. 40.

4. Heat pump for thermal power production in dairy farm
ABSTRACT Besides cold for milk cooling, dairy facilities need to produce hot water for cleaning of tools and equipment. Overall, ohmic heating has been used in dairy farms, increasing power consumption and manufacturing costs. Therefore, as an alternative to reduce power consumption, this paper proposed a water-water heat pumping for simultaneous cold and he

5. Labneh with probiotic properties produced from kefir: development and sensory evaluation
The labneh or labaneh is a popular fermented milk in the Middle East. Another fermented product that deserves special mention is kefir since it has probiotic activity and unique sensory, nutritional, and therapeutic properties. The aim of the present study was to develop a functional probiotic labneh using kefir as a fermenting agent and to perform a sensory

6. Adhesion and production of degrading enzymes by bacteria isolated from biofilms in raw milk cooling tanks
Biofilms in milk cooling tanks compromise product quality even on farms. Due to the lack of studies of this topic, this study evaluated the microbiological conditions of raw milk cooling tanks on farms and characterized the microorganisms isolated from these tanks. Samples were wiped off with sterile swabs from seven milk cooling tanks in three different poi

7. Evaporative cooling for lactating sows under high ambient temperature
Two experiments were conducted to evaluate the evaporative cooling of the air at farrowing on the performance of lactating sows under high environmental temperature conditions in the Central West region of Brazil. One hundred and forty-four lactating sows - 46 of first and second farrowing (experiment I) and 98 from the third to eighth farrowing (experiment

8. Ocorrência de leite ácido e de resíduos de antimicrobianos no leite cru entregue em laticínios na região do Vale do Taquari, RS, Brasil = Occurrence of acidity and antimicrobial residues in raw milk delivered at a dairy plant in Vale do Taquari, RS, Brazil / Occurrence of acidity and antimicrobial residues in raw milk delivered at a dairy plant in Vale do Taquari, RS, Brazil
Background: Milk is considered one of the most important sources of nutrients. It contains proteins, fat acids, vitamins and minerals. Its activity has a significant socio-economic impact in all over the world and in Brazil. The presence of bacterial inhibitors in milk for human consumption is a great concern for the dairy products industry and public health

10. Fuzzy control and variable speed drive system cooling tank / Controle Fuzzy e acionamento a velocidade variável de sistema resfriador de leite
This work presents the application of control techniques to drive single-phase induction motors with the aim of improving the performance of cooling systems. The control system is based on Fuzzy Logic and is applied to a three-phase PWM inverter adapted to drive singlephase motors with volts per hertz technique. The main feature of the work is to control the

11. Use of QFD (Quality Function Deployment) in order to improve milk quality / Uso do metodo DFQ (Desdobramento da Função Qualidade) para melhoria da qualidade do leite fluido
Brazil produces about 130 liters per capita per year, below the rate recommended by the United Nations of 215 liters per capita per year. In the United States, the main reason for the rejection of milk by the consumer is associated with the presence of off flavors. Therefore, the Department of Agriculture of this country was responsible for developing a lang
