The choice of strain, substrate, and environmental conditions are fundamental factors that determine the ability of a fungus to develop and produce mushrooms with high quality. The objective of this study was to compare the strains of Lentinula edodes and Ganoderma lucidum originated from South Korea and Brazil in relation to their vegetative development in different culture media, to obtain isolates with high quality. The strains of the two mushroom species from Brazil and South Korea grew slowly, possibly because of abiotic factors or storage technique used. However, it may be concluded that temperature, humidity, light, pH, and nutrients from the substrate, if not regulated appropriately may affect the vegetative species.

Brazil and the Middle-Income Trap: Its Historical Roots

Eduardo da Motta e Albuquerque 서울대학교 경제연구소 2019 Seoul journal of economics Vol.32 No.1

This paper evaluates the alternation between catching up periods and falling behind periods in Brazilian economic history, with data from 1870 to 2016. This alternation expresses the middle income trap. A tentative theoretical framework is presented, suggesting a two-dimensional process, with external forces (basically technological revolutions in leading countries) increasing the gap between Brazil and the leading economy, and internal forces (basically planned or unplanned internal efforts, especially industrial policies) reducing that gap. The historical origins of this long term middle income trap is discussed, with a special focus in the role of income inequality.

Room temperature photoluminescence of BCT prepared by Complex Polymerization Method

F.V. Motta,A.P.A. Marques,J.W.M. Espinosa,P.S. Pizani,E. Longo,J.A. Varela 한국물리학회 2010 Current Applied Physics Vol.10 No.1

It was used the Complex Polymerization Method to synthesize barium calcium titanate powders (BCT). Crystalline Ba0.8Ca0.2TiO3 perovskite-type phase could be identified by X-ray diffraction and confirmed by Raman spectroscopy in the powders heat treated at 600 C. Inherent defects, linked to structural disorder,facilitate the photoluminescence emission. The photoluminescent emission peak maximum was around of 533 nm (2.33 eV) for the Ba0.8Ca0.2TiO3. The photoluminescence process and the band emission energy photon showed dependence of both the structural order–disorder and the thermal treatment history. The results revealed that Ba0.8Ca0.2TiO3 (BCT20) is a highly promising candidate material for optical applications.

A NEW BOOK: 'LIGHT-WATER REACTOR MATERIALS'

OLANDER DONALD R.,MOTTA ARTHUR T. Korean Nuclear Society 2005 Nuclear Engineering and Technology Vol.37 No.4

The contents of a new book currently in preparation are described. The dearth of books in the field of nuclear materials has left both students in nuclear materials classes and professionals in the same field without a resource for the broad fundamentals of this important sub-discipline of nuclear engineering. The new book is devoted entirely to materials problems in the core of light-water reactors, from the pressure vessel into the fuel. Key topics deal with the $UO_2$ fuel, Zircaloy cladding, stainless steel, and of course, water. The restriction to LWR materials does not mean a short monograph; the enormous quantity of experimental and theoretical work over the past 50 years on these materials presents a challenge of culling the most important features and explaining them in the simplest quantitative fashion. Moreover, LWRs will probably be the sole instrument of the return of nuclear energy in electric power production for the next decade or so. By that time, a new book will be needed.

Curcuminoid-phospholipid complex induces apoptosis in mammary epithelial cells by STAT-3 signaling

Curcumin (from the rhizome of Curcuma longa) is well documented for its medicinal properties in Indian and Chinese systems of medicine where it is widely used for the treatment of several diseases. Epidemiological observations are suggestive that curcumin consumption may reduce the risk of some form of cancers and provide other protective biological effects in humans. These biological properties have been attributed to curcuminoids that have been widely studied for their anti-inflammatory, anti-angiogenic, antioxidant, wound healing and anti-cancer effects. In this study we have investigated on the effect of a curcumin phospholipid complex on mammary epithelial cell viability. HC11 and BME-UV cell lines, validated models to study biology of normal, not tumoral, mammary epithelial cells, were used to analyse these effects. We report that curcumin acts on STAT-3 signal pathway to reduce cell viability and increase apoptosis evaluated by the the amount of activated caspase 3. Further it reduces MAPK and AKT activations. JSI-124, a STAT-3 inhibitor (100 nM) was able to block the negative effect of curcumin on cell viability and caspase 3 activation. Finally the negative effect of cucumin on cell viability has been impaired in STAT-3i HC11, where STAT-3 protein was greatly reduced by shRNA-interference. These results indicate that curcumin presents a potential adverse effect to normal mammary epithelial cells and that it has a specific effect on signal trasduction in mammary epithelium.

LOW GLOBAL WARMING REFRIGERANTS FOR RESIDENTIAL AIR CONDITIONING APPLICATIONS

MARK SPATZ,SAMUEL YANA MOTTA,CHRISTOPHER SEETON,YONGMING NIU 대한설비공학회 2014 International Journal Of Air-Conditioning and Refr Vol.22 No.2

Due to the growing global concerns around the use of refrigerants with relatively high globalwarming potential, new refrigerants with the positive attributes of both high thermal performanceand low environmental impact are currently in development by Honeywell. These new refrigerantsexhibit promising performance when compared with refrigerants currently used in stationary ACsystems such as those that use R-410A, R-407C, and R-134a, for example. These new refrigerantsalso show significantly lower flammability characteristics than the much more flammablehydrocarbons. Replacements of common HFC refrigerants such as R-410A and R-407C are discussedfor residential air conditioning applications. Thermal properties as well as experimentalresults in representative air conditioning systems are presented, showing the benefits of usingthese new refrigerants.

Purpose: This study aimed to describe the growth, body protein status, and micronutrient biomarkers of Brazilian infants with cow’s milk allergy (CMPA) at baseline and at 18 months of follow-up in comparison with their healthy peers. Methods: Thirty infants with CMPA younger than six months of age were included in this longitudinal study, and their nutritional status was compared with that of 24 non-allergic age-matched children. Anthropometric measurements were used to assess growth, and blood and urine samples were analyzed for protein and micronutrient status. Mixed linear models adjusted for birth weight, socioeconomic status, infant feeding at baseline, weightfor- age, C-reactive protein, serum albumin, micronutrient dietary supplementation, and salt consumption were employed to evaluate the evolution of nutritional parameters throughout the follow-up period. Results: Overall, the mean age of the children at enrolment was 2.9 (standard deviation 1.7) months, and 29 children (53.7%) were male. Infants with CMPA showed a higher prevalence of functional iron depletion (transferrin saturation <20) (p=0.027), lower serum ferritin (p=0.009), and lower urinary iodine (p=0.034) levels than non-allergic children at baseline. Patients with CMPA showed a higher increment in weight-for-age and length-for-age over time than those in the control group (p<0.01). Mixed linear analyses showed a significantly lower increase in serum vitamin B12 (s-B12) (p=0.001) and urinary iodine (p<0.001) concentrations over time compared to the control group. Conclusion: Infants with CMPA on a cow’s milk elimination diet had a higher weight and length at 18 months of follow-up but showed signs of inadequate iron, iodine, and B-12 vitamin status.
