1. INITIAL DEVELOPMENT AND TOLERANCE OF PEPPER SPECIES TO SALINITY STRESS
RESUMO A salinidade é uma das principais causas da queda de rendimento das culturas, em regiões áridas e semiáridas, sendo necessária a utilização de espécies tolerantes que viabilizem o cultivo nestas áreas. Nesse sentido, objetivou-se verificar a emergência, o crescimento inicial e a tolerância de espécies de pimenta irrigadas com águas salina

2. Experimental bedforms by saline density currents
Abstract Bedforms are sedimentary features that can be generated on the seafloor by the interaction between density currents and mobile beds. Developing knowledge about the hydraulic and sedimentary processes involved during these events is in the interest of research groups and oil companies. Because of the magnitude of the density currents in its natural e

3. Growth and production components of West Indian cherry cultivated with saline waters and potassium fertilization
RESUMO Devido às limitações hídricas tanto em termos quantitativos como qualitativos na região semiárida do Nordeste brasileiro, o uso de águas com elevadas concentrações de sais torna-se necessário para agricultura irrigada. Deste modo, objetivou-se com este trabalho, avaliar o crescimento e a produção da aceroleira enxertada sob irrigação com

4. Potentially mobile of heavy metals on the surface sediments in tropical hyper-saline and positive estuaries
ABSTRACT Estuarine sediments represent important pools of trace metals, released from both anthropogenic and natural sources. Fluctuations in the water column physicochemical conditions, on the other hand, may transfer metals from solid to liquid compartment and resulting in contamination of the surrounding environment. The present research was carried out t

5. A Bayesian analysis of the parasitic ecology in Jenynsia multidentata(Pisces: Anablepidae)
ABSTRACT Jenynsia multidentata Jenyns, 1842 (one-sided livebearers) are euryhaline viviparous fish of small size, used in the laboratory experiment, important as resource for biological control of mosquito’s larva and a key species to recover eutrophic lakes. Works have been published dealing with parasite biodiversity of this host, but little has been stu

6. SUBSTITUIÇÃO DO NITROBENZENO PELO ÓLEO DE SOJA COMO UMA PROPOSTA PARA O ENSINO DO MÉTODO DE VOLHARD EM ANÁLISE QUANTITATIVA
Volhard method is extensively employed in the teaching laboratories of classical quantitative analysis to chloride determination and is based on the reaction of Ag+ with Cl- and Ag+ residual titration with SCN-. Its drawback is that SCN- reacts with the AgCl(s) initially formed. Nitrobenzene is used to avoid this stripping, but it is toxic to the environment

7. Diversity and Efficiency of Rhizobia Communities from Iron Mining Areas Using Cowpea as a Trap Plant
ABSTRACT Mining is an important economic activity. However, its impact on environment must be accessed, mainly on relevant processes for their sustainability. The objective of this study was to evaluate the diversity and efficiency of symbiotic nitrogen fixing bacterial communities in soils under different types of vegetation in the Quadrilátero Ferrífero:

8. Comportamiento bi-modal de una fundición gris y un acero estructural al carbono en corrosión atmosférica marina acelerada
ABSTRACT According to data gathered in the last Metal Foundry Industrial Production Survey [1], approximately 46% of the industrial production of ferrous alloys is gray-iron. In this context the study of the atmospheric corrosion resistance of gray-iron becomes interesting to asset its useful life when subject to weathering conditions. The studies of gray-ir

9. Interaction of dental pulp stem cells with Biodentine and MTA after exposure to different environments
ABSTRACT Objective: The aim of the present study was to evaluate and compare the cytotoxic effects of Biodentine and MTA on dental pulp stem cells (DPSCs) and to assess cell viability and adherence after material exposure to an acidic environment. Material and Methods: DPSCs were cultured either alone or in contact with either: Biodentine; MTA set for 1 ho

10. Antiseptics and microcosm biofilm formation on titanium surfaces
Abstract Oral rehabilitation with osseointegrated implants is a way to restore esthetics and masticatory function in edentulous patients, but bacterial colonization around the implants may lead to mucositis or peri-implantitis and consequent implant loss. Peri-implantitis is the main complication of oral rehabilitation with dental implants and, therefore, it

11. Decolorization of azo dyes (Direct Blue 151 and Direct Red 31) by moderately alkaliphilic bacterial consortium
Abstract Removal of synthetic dyes is one of the main challenges before releasing the wastes discharged by textile industries. Biodegradation of azo dyes by alkaliphilic bacterial consortium is one of the environmental-friendly methods used for the removal of dyes from textile effluents. Hence, this study presents isolation of a bacterial consortium from soi

12. Environmentally-assisted Fatigue Crack Growth in AA7050-T73511 Al Alloy and AA2050-T84 Al-Cu-Li Alloy
The aim of this study was to evaluate and compare the effect of low temperature and saline environment on the fatigue crack growth behavior of the AA7050-T7451 Al alloy and the recently developed AA2050-T Al-Cu-Li alloy. Fatigue at room and low temperature and corrosion-fatigue tests were carried out using an applied stress ratio (R) of 0.1, 15 Hz frequency
