Afforestation, as a tool to mitigate carbon emission is constrained by available land areain several countries, but Iran has the potential of plantation. In doing so, differences in soilstocks between tree species could give an indication of the effects of future managementchanges. Hence, a better understanding of tree species traits on soil properties is required topredict how changes in ecosy...

Effect of haying (hayed or not hayed prior to tillage), tillage (notillage, minimum tillage, or conventional tillage), and N fertilization (0 or 67 kg ha ') on surface infiltration rates, Q(h), was evaluated for Conservation Research Program (CRP) site conversion. Soils included Amor loam (fine-loamy, mixed, superactive, frigid Typic Haplustoll) and Cabba silt loam (loamy, mixed, superactive, c...

Much effort has been expended in the search for new effects. These include searches for charged and neutral fundamental scalars, new families of quarks, new leptons, lepton-quark substructure, and supersymmetric particles, plus many other topics. In this report I will discuss a few of these experiments in some detail, some in a broader review, and unfortunately some not at all. For those that I...

We analyze the partial decay widths of sfermions decaying into charginos and neutralinos Γ(f̃ → f ′χ) at the one-loop level, including the electroweak and strong corrections. We present the renormalization framework, and discuss the value of the corrections. Since these corrections show non-decoupling effects, we analyze the radiative effects induced by a heavy squark sector into the lepton-slep...

Tevatron experiments have recently set or improved limits on quark and lepton compositeness. Included here are results from p s = 1:8 TeV pp collider experiments D and CDF and from xed target neutrino experiment CCFR, who report limits on quark-quark, quark-lepton, and quark-neutrino compositeness, respectively.

After logging, 17% of the stumps left in pondcypress (Taxodium distichum var. nutans) swamps produced sprouts that persisted for several years. Significantly more sprouts were present on stumps with diameters < 60 cm (perhaps left from younger trees) and shorter than 70 cm. Stumps in large openings and from trees cut in winter tended to have more sprouts than stumps left in thinned swamps and f...
