We quantified the dynamics of the tree stratum at Hubbard Brook Experimental Forest (HBEF), New Hampshire, to examine why live biomass reached a plateau in about 1980. Total aboveground biomass increased from 209 Mg ha–1 in 1981 to 216 Mg ha–1 in 2001. From 1991 to 2001, in-growth of ‡10 cm diameter at breast height (DBH) trees averaged 4.7 trees ha–1 year –1 with a corresponding in-growth biom...

One important barrier to cancer immunotherapy. We used cyclic dinucleotides (CDNs) and Listeria vaccine and LPS treated HA-specific CD8 tolerance B10. D2 mice. Our results demonstrated T cells IFN-gamma increased in CDNs and Listeria vaccine plus CDNs treatment groups. But CDNs didn’t significantly increase Treg cells. The data showed CDNs can reverse established T cell tolerance that improved ...

The experiment was conducted at Dobila, Tarash of Shirajgonj in Chalan Beel during rabi season 2016-17 and 2017-18. treatments were four wheat varieties viz. ‘BARI Gom-25’, Gom-26’, Gom-28’ Gom-30’. Wheat var. Gom-30’ produced the highest grain yield (5.02 t/ha 4.83 2017-18 with pooled value 4.93 t/ha) associated higher number spikes/m2 (372-444/m2 408/m2) grains/spike (pooled 45/spike). requir...

Abstract The objective of this work was to evaluate the losses N-NH3 by volatilization and agronomic efficiency a mixture urea with natural zeolite, as topdressing fertilization, in an area for commercial production roses (Rosa spp.). treatments were: two rates (60 120 kg ha-1), without zeolite. N sources were applied directly soil surface, determined using free semi-open static chamber. quanti...

The study deals with organic, mineral and organo-mineral systems of winter wheat fertilization in the conditions Volga forest-steppe. According to organic system, straw predecessor, green manure Biocomposite-correct were introduced into soil (typical medium-thick medium loamy chernozem) for mass (vetch-oat mixture). system included two options: applied together nitrogen a dose 10 kg per 1 ton z...

Biochar and zeolite, due to their porous structure, are supposed be appropriate soil amendments especially in agricultural areas with a lack of water or unsuitable soils coarse texture. Two additions that intended assist an increase content (AWC) biochar zeolite. With this aim, the effects zeolite at two levels 5 10 t ha?1 (known as B5, B10, Z5, Z10) on hydrological properties consequently corn...

Programmed Cell Death-1 (PD-1) is an inhibitory immune receptor, which plays critical roles in T cell co-inhibition and exhaustion upon binding to its ligands PD-L1 and PD-L2. We report the crystal structure of the human PD-1 ectodomain and the mapping of the PD-1 binding interface. Mutagenesis studies confirmed the crystallographic interface, and resulted in mutant PD-1 receptors with altered ...

This is the first large-scale study to assess climate change impact on grain yield of rainfed wheat for three provinces contrasting climatic conditions (temperate, cold semi-arid, and hot arid) in Iran. Five integrative scenarios including +0.5°C temperature plus−5% precipitation, +1°C plus−10%, +1.5°C plus−15%, +2°C plus−20%, +2.5°C plus−25% were used evaluated. Nitrogen fertilizer shifting pl...

Atmospheric carbon sequestration in terrestrial ecosystems has become a significant challenge the global framework of reducing greenhouse gas emissions. The main objective this study is to provide estimation organic stocks agricultural soils Sidi Bel Abbes plain at various depths and according different land use, namely cereals, olives and,viticulture. We have chosen two toposequences types tha...
