Effect of Profitability and Growth Rate of Corporate Values
Yuni Kusuma Arumsari
Abstract This study aims to examines and analyzes the effect of profitability and firm growth on firm value. This study also aims to find out more information about the profitability and growth of the company on corporate values both from the agency and simultaneously. This study used a hypothesis related to the analysis of the data examined, along with data collection techniques used were documentation. This research is the development, which is a repetition of the research study - a similar but previous studies with samples, variables, and different periods. This study also used the partial test and simultaneous test aimed to determine the effect of partial and simultaneous. Results from the study showed that the company's profitability partial effect on the value of the company with a value of t> t table that is equal to 3,013> 1,860 and sig <0.05, Positive t value means a positive influence, if profitability increases, the value of the company will also increase. Based on that show that the more the company's profitability in the company's annual report will further enhance shareholder value. For the company's growth is partially affected by the t count> t table that is equal to 2,189> 1,860, this shows the influence of the growth of the value of the company. Positive t value means a positive effect, namely if growth increases, the value of the company will also increase. Based on the above shows that the higher growth in the company's annual report will further enhance shareholder value. While simultaneously affect the profitability and growth of the company value. It can be seen from the analysis of variable profitability and growth of the company to the value of the company has calculated F value of 22.784 while the F table (α = 0:05; regression df = 2: residual df = 7) was 4.74. Because the F count> F table is 22.784> 4.74 or the Sig. F (0,049) <α = 0.05 then regression analysis model is significant. This means that H0 rejected and H1 accepted so that it can be concluded that the value of the company can be significantly influenced by the profitability and growth.

Migration of Plastic Bag Additives in Attiéké (A Fermented Cassava-based Couscous in Côte d'Ivoire)
Kombo Mananga Olivier Simon, Gnagne Agnes Essoh Jean Eudes Yves, Gadji Alahou André Gabazé, Ballet Guy Tiama et Yapo Ossey Bernard
Abstract Attiéké, a couscous made from fermented cassava, is a staple food in Côte d'Ivoire packaged at high temperatures in polythene plastic bags for selling in the Ivorian markets. Antioxidants (BHT and Irgafos168), phthalates (DEP and DIBP) and UV stabilizers (Chimassorb 81 and Chimassorb 944) were analyzed by high performance liquid chromatography both in the plastic bags and in attiéké (from the surface to the inside of the attiéké ball) at different temperatures in order to study their migration into this foodstuff. Chimassorb 944 migrates almost only on the contact surface between the plastic bags and the attiéké ball from 40 to 60°C and up to 1cm at 70°C. However, the other five additives migrate from the surface of the attiéké ball up to 1.5 cm inside from 40°C to 70°C after three hours of conditioning. At 30°C, migration is almost zero for all the additives studied.

The Role of Agricultural Production Economies in Achieving Food Security in Sudan during the Period (2015-2018)
(A Case study of Sorghum, Millet and Wheat)
Elfatih Mohamed Osman Mukhtar
Abstract This study aimed to identify the role of agricultural production economies in achieving food security in Sudan during the period 2015 - 2018 (A case study of sorghum, millet and wheat) by recognizing the concept of agricultural production economies and its objectives and the factors that influence the agricultural production. It also aims to identify the concept of food security and its dimensions. To achieve the objective of the study, the researcher followed the deductive approach to state the problem and the hypotheses. The study also followed the historical, analytical approach and case study approach to highlight the role of agricultural production economies in achieving food security in Sudan during the period 2015 – 2018. The study concluded with many results; the most important of which is that the productivity of the essential food crops (sorghum, millet and wheat) did not meet the local needs due to increase of prices of these crops significantly and the majority of the population is unable to afford to buy them. The results also showed that one of the main reasons that led to this meager production of the basic food crops (sorghum, millet and wheat) is the lack of financing of agricultural production. The imposition of heavy taxes and fees on farmers resulted in their reluctance to grow these crops, as well as the lack of fuel, and cash, fluctuation of rain, and all have a negative impact on food security. Moreover, the lack of security led to low production of sorghum and millet where they are grown in Darfur, Blue Nile State, and Kordofan and Nuba mountains. These regions are areas of conflicts abandoned by farmers, the thing that led to widen gap of food security in Sudan.

Somaya S. Mohamed, Mohammed A. Hassan, Migdam E. Abdelgani
Abstract One of the main problems in rhizobial inoculant technology is the poor survival of microorganisms during storage. Liquid inoculants amended with polymers has considered as a solution to the problems associated with shorter shelf life and poor quality. This study was conducted to improve the shelf life of previously selected liquid formulations of rhizobial strains TAL 380, TAL 209, TAL 1399, ENRRI 1, USDA 3385 and USDA 3100. The polymeric additives used were polyvinylpyrrolidone (PVP), polyethylene glycol (PEG), polyvinyl alcohol (PVA) and Gum Arabic. Yeast Extract Mannitol (YEM) broth without the addition of polymers and charcoal based inoculant were used as check treatments. The formulated liquid inoculants were stored at room temperature (25-35°C) and under refrigeration at 4°C for a period of two months. Spread plate method was used to determine the colony forming units (CFU) per ml at two weeks intervals. Liquid inoculants formulated with PEG (0.1%),PVP (1% and 2%), PVA (1% and 3%), and Gum Arabic (0.3%) supported the growth of ENRRI 1, TAL 380, USDA 3100, TAL 1399, TAL 209, and USDA 3385, respectively. Charcoal based inoculant harboured lowest cell counts when compared to liquid inoculants amended with the polymeric additive. The results revealed that all tested formulations were able to support cell growth as high as 109 CFU/ml and liquid Rhizobium inoculants amended with polymeric additives can be stored without loss of viability for two months at both room temperature and at 4°C. In conclusion, the study suggests the efficiency of these polymeric additives in improving the shelf life of rhizobial liquid inoculants.

Abstract Allelopathy can be considered as any effect, beneficial or harmful, of a plant towards another, in the presence of chemical compounds in the environment. In this context, the present paper, has its aim to assess the influence of allelopathy in the aqueous extract of the aerial part of the canola plant (Brassica napus), about the germination of sunflower seeds (Helianthus annuus). The experimental outline used has been entirely randomized with four repetitions in total. The treatments were as follows: concentrations of 1, 2.5, 5 and 10% of the canola aqueous extract and the witness plant with distilled water, conducted in germitest paper with 50 seeds per roll, under a temperature of 27ºC. Daily account of germinated seeds has been carried out and at the end of eight days, germination percentage, vigor, average speed of germination and average time for germination have also been analyzed. Lilliefors, not existing a need of transformation, submitted the obtained data to the normality test the averages were compared by the Tukey Test (P≤0. 05), through the computerized application WinSTAT®. The aqueous canola extract affected the variables of germination of the sunflower seeds in a negative way. It is recommended to be cautious about the use of sunflower coming about the canola culture, thus field experiments should be conducted in order to attest such effect.

Analysis of concrete applied after prolonged mixing time
Charles Ferreira de Oliveira, Gabriel Henriques Rabelo Gouvêa, Luiz Antônio Melgaço Nunes Branco
Abstract The Brazilian Standard NBR – “Norma Brasileira” 7212 (ABNT – “Associação Brasileira de Normas Técnicas”, 2012) recommends that ready mixed concrete, transported by mixer truck for longer than 1.5 hours, must be refused by the user. It also advises that concrete shall not be released and thickened in a period exceeding 2.5 hours after the addition of water to the mixture, considering such concrete as overdue. It is common to see delays in concrete operations, so it is important to know the main properties of concrete used after prolonged mixing time. Further more, material waste is a worldwide problem and concrete is significantly wasted in construction activities. This study tests the hypothesis of using concrete after prolonged mixing time and aims to evaluate changes in key properties of a concrete dosed with Portland cement Type III (ASTM – American Society for Testing and Materials), mixed during 4 hours without the use of setting time retardant, hourly assessing changes in workability, stiffness, compressive strength and corrosion potential. Resonant frequency, electrical volumetric resistivity and compressive strength tests were performed. The results showed that even with the use of superplasticizer, there was great loss of concrete slump. It was also noted an increasing tendency of the dynamic modulus of elasticity and a decreasing tendency of the electrical resistivity of the concrete, but there was no significant loss in strength during the assessment time. Even though resistivity shows that the higher the mixing time, the greater will be the propensity of concrete not to protect the reinforcement bars, it is concluded that it is still possible to use concrete after the mixing time recommended by NBR 7212: 2012 and this way reduce material waste in civil construction.

Selection of Pinus Taeda Progenies for Greater Income in Cellulose and Paper Production
Vinícius Rosa Schweitzer, Martha Andreia Brand, Silvana Nisgoski, Jorge Luis Monteiro de Matos, José Guilherme Prata
Abstract Brazil is the second largest producer of pulp and eighth in paper production in the world, among the most used species, or Pinus taeda is a major highlight, especially in the production of pulp and kraft paper. Pinus taeda is a second most planted species in Brazil, especially in the colder regions of the country, where it has high rates of development, reaching a rate of over 30m³ / ha / year. The objective of this research work was to characterize ten Pinus taeda progenies, based on the characteristics of the basic specific mass and the dimensions of its fibers, having as main focus the use of these trees in the pulp and paper production. The study analyzed 28 trees of ten different 18 year old Pinus taeda progenies. These trees were collected in the municipality of Otacilio Costa, state of Santa Catarina. The progenies were analyzed based on the following properties, specific mass, length, inner diameter, outer diameter and wall thickness of the fibers, aggregating as fiber measurements, also used correlations among them, flexibility coefficient, wall fraction, index weakening and Runkel index. The main results obtained in this work were that the progenies, although growing under conditions equal to development, present significant differences between the analyzed variables. Fiber length were the most prominent in fiber measurements, exceeding the values referenced by up to two times, the other measurements, wall fraction, internal and external diameter, if equivalent to the values surveyed. The relationships determined between the measurements of the raw fibers show great importance in the progeny selection process, as well as the Pearson correlations applied to the measured variables, observing the behavior of the basic specific mass, which alone does not provide reliability in this work. However, when analyzed together with the other data, it makes the selection process reliable. The selection of Pinus taeda progenies using the properties of tracheids is possible, combining the basic specific mass and increasing the confidence in selection. The progenies that stood out the most were 12, 21, 74 and 112, these were selected because they have greater balance among the analyzed variables, being the number 112 the best among them because it has the largest basic specific mass, added to the other characteristics, provides greater benefits in pulp and paper production.
