Background: The aim of this study was to determine how maternal undernutrition during pregnancy and offspring birth-weight can affect the postnatal development of offspring under farm conditions, which may lead to consequences in its meat and carcass quality. The current study involved a total of 80 litters from Iberian sows fed a diet fulfilling daily requirements(n = 47; control) or providing 70% daily requirements(n = 33; underfed) from d 38 to d 90 of gestation when fetal tissue development begins. After birth, piglets born live were classified as low birthweight(LBW; control and 230 underfed pigs(50% males and females) distributed by BW category and sex were studied until the ***: At birth and weaning, there were significant differences in all morphological measures and weight between NBW and LBW piglets as expected(P cts of the gestational feed restriction.

Addition of Urban Waste to Semiarid Degraded Soil:Long-term Effect

引用

Pedosphere 2007年第5期17卷 557-567页

The addition of municipal solid wastes （MSW） is considered as a possible strategy for soil rehabilitation in southeast Spain. The objective of this study was to evaluate the long-term （17 years） effect of five doses of MSW addition on the microbiological, biochemical, and physical properties of semiarid soil. Increased values of several parameters that serve as indicators of general microbiological activity, such as, basal respiration, adenosine triphosphate （ATP） or dehydrogenase activity; microbial population size （microbial biomass c）, and extracellular hydrolase activity related to macronutrient cycles, such as, urease, 3-glucosidase, and N-a-benzoyl-L-argininamide protease, were observed in the amended soils. The highest MSW doses showed the highest values in these hydrolase activities. The incorporation of municipal waste resulted in a more dense development of the plant cover, 50% greater in higher doses than in the control treatment, which generated a substantial increase in several c fractions. Total organic carbon reached 12 g kg^-1 soil with the highest MSW doses, compared to 4.30 g kg^-1 soil in the control treatment. The physical properties of the soil were also improved, showing greater percentage of stable aggregates and water holding capacity. Positive correlation coefficients between c fractions and parameters related to microbial activity and aggregate stability were observed. Although these improvements were greater in the soils receiving the highest doses of organic amendment, the increases were not proportional to the amount added, demonstrating the existence of a threshold, above which an increase in the amount of organic matter added is not reflected in an increase in the soil＇s physical, biochemical, and microbiological properties. However, the addition of municipal solid wastes proved its suitability for improving soil quality, thereby indicating the potential of such an amendment, to prevent desertification in Mediterranean areas such as th

An incubation experiment was designed in order to determine the further microbiological response to an addition （500 m3 ha-1） of fresh olive mill wastewater （FOMWW） in a soil that has been frequently amended with uncontrolled doses of OMWW since the 1990s in an active disposal site （ADS soil）. To achieve this aim, the phospholipid fatty acid （PLFA） profiles, microbial biomass c （cmic）, and dehydrogenase （DHA） and urease activities （URA） were monitored at the beginning （To）, 3 h （T1） and 97 d （Tf, i.e., the end） of incubation after FOMWW addition. After the FOMWW addition, an increase in the ratio of fungal to bacterial PLFAs was observed in ADS soil. Moreover, a relative increase of monounsaturated fatty acids （MUFAs） with respect to saturated fatty acids （SATFA） was found in the ADS soil. An increase of the Gram-positive to Gram-negative ratio was observed in this soil at the end of the incubation. While DHA and cmic increased in the ADS soil after FOMWW addition, URA showed a decrease. Fungi and Gram-positive bacterial biomass experienced an increase after addition of a high dose of FOMWW in laboratory conditions.

Oligo-carrageenan kappa increases c, N and S assimilation, auxin and gibberellin contents, and growth in Pinus radiata trees

Journal of Forestry Research 2015年第3期26卷 635-640页

Oligo-carrageenans （Ocs） obtained from pure carrageenans extracted from marine red algae stimulate growth by enhancing photosynthesis and basal metabolism in tobacco plants and Eucalyptus trees. In addition, Ocs stimulate secondary metabolism, increasing the level of metabolites involved in defense against pathogens. In this work, we analyzed the effect of Oc kappa on the increase in height, in activities of basal metabolism enzymes in- volved in carbon, nitrogen and sulphur assimilation, ribu- lose 1,5 biphosphate carboxylase/oxygenase （rubisco）, glutamate dehydrogenase （GDH） and O-acetylserine thiol- lyase （OASTL）, and in the level of growth-promoting hormones, the auxin indole acetic acid （IAA） and the gibberellin GA3, in pine （Pinus radiata） trees treated with Oc kappa at concentrations of 1 and 5 mg mL-1 and cultivated for 9 months without additional treatment. Pines treated with Oc kappa at 1 mg mL-1 showed a similar increase in height but displayed a higher increased in total chlorophyll, activities of rubisco, GDH and OASTL and level of IAA and GA3 than those treated with Oc kappa at 5 mg mL-1. Thus, Oc kappa stimulates growth and basal metabolism and increases the level of growth-promoting hormones in pine trees, mainly at 1 mg mL-1.

Status and prospects for symmetric organic redox flow batteries

引用

Journal of Energy chemistry 2025年第1期100卷 125-143页

作者： Md Al Raihan c.Adam Dyker Department of chemistry University of New Brunswick

As environmental concerns from fossil fuel consumption intensify, large-scale energy storage becomes imperative for the integration of renewable sources like wind, hydro, and solar with the electrical *** flow batteries, particularly those employing organic molecules, are positioned as a key technology for this purpose. This review explores the growing field of symmetric organic redox flow batteries(ORFBs) within this context. Unlike traditional asymmetric designs based on unique active materials for each electrode, symmetric ORFBs involve a single bipolar species for both electrodes. This review highlights the benefits of a symmetric design, and categorizes five distinct classes of organic bipolar molecules used in both aqueous and non-aqueous solvents. By providing a comprehensive overview of their cell cycling and performance characteristics, the strengths and weaknesses of the diverse categories of bipolar molecules are highlighted for both solvent systems, as are opportunities for future development. This should guide new research directions and advance the development of practical symmetric ORFBs.

Information about olive-tree irrigation in sub-humid climates, as in Uruguay, is scarce. Water consumption of young olive trees, Arbequina variety, was measured for two years with six drainage lysimeters, protected from rain by an automatic rain-out shelter. Irrigation water volume and drainage of each lysimeter were measured daily and soil moisture was registered twice a week with neutron probe at four depths. Evapotranspiration (ETc) was calculated by volume balance. Data periods when available water descended below 50% or increased over 100% were eliminated, as those in which the stem water potential was below -1.5 MPa. Water consumption values were averaged within 7- to 14-day periods, expressed in mm·d-1, and referred to a 2.5 × 5.5 m plantation framework without vegetation cover. There was a positive linear relation of the summer crop coefficient (Kc mid) with age, canopy cover percentage and canopy volume. canopy cover percentage was the parameter which explained most of the variation of Kc mid, which ranged between 0.13 and 0.24, with 5% and 46% canopy cover, respectively. Full irrigation, associated to a good drainage resulted in a rapid growth of the young plants, bringing forward the start of full production period. This represents useful information for the adjustment of irrigation in olive-tree orchards, to accelerate growth with a rational and sustainable use of both water and energy in Uruguay.
