Gestão zootécnica e genética informatizadas em pequenos ruminantes: uma revisão

open access: yesMedicina Veterinária, 2020
A criação de pequenos ruminantes tem se expandido em todos os estados brasileiros e, independentemente do objetivo da exploração, tem muito a contribuir para o desenvolvimento socioeconômico do país.

Photo-emission of two protons from nuclei

open access: yes, 2004
The photo-emission of two protons from the $^{12}$C, $^{16}$O and $^{40}$Ca nuclei is investigated. Aim of the work is the study of the possibilities offered by this probe to obtain information about the characteristics of the short-range correlations ...

Tuning the selectivity of CO2 conversion to CO on partially reduced Cu2O/ZnO heterogeneous interface

open access: yesInterdisciplinary Materials, Volume 3, Issue 3, Page 380-388, May 2024.
Cu2O/ZnO heterostructure with partially reduced matal/oxide heterostructure in zinc plate (CZZ) is synthesized, and the effectiveness of CZZ as a CO2RR catalyst is verified, resulting in an improved catalyst performance with a CO selectivity of up to 70.9% at −0.95 V versus reversible hydrogen electrode, while maintaining a stability of 24 h.

GIGANTEA accelerates wheat heading time through gene interactions converging on FLOWERING LOCUS T1

open access: yesThe Plant Journal, Volume 118, Issue 2, Page 519-533, April 2024.
SUMMARY Precise regulation of flowering time is critical for cereal crops to synchronize reproductive development with optimum environmental conditions, thereby maximizing grain yield. The plant‐specific gene GIGANTEA (GI) plays an important role in the control of flowering time, with additional functions on the circadian clock and plant stress ...

Formation of Lean Premixed Surface Flame Using Porous Baffle Plate and Flame Holder

open access: yesJournal of Thermal Science and Technology, 2013
A lean premixed surface flame has many advantages including low CO(Carbon Monoxide) and NOx(Nitrogen Oxide) emission and applicability of a small combustion volume leading to compact design.

Low-lying magnetic excitations of doubly-closed-shell nuclei and nucleon-nucleon effective interactions

open access: yes, 2009
We have studied the low lying magnetic spectra of 12C, 16O, 40Ca, 48Ca and 208Pb nuclei within the Random Phase Approximation (RPA) theory, finding that the description of low-lying magnetic states of doubly-closed-shell nuclei imposes severe constraints

Random Phase Approximation and neutrino-nucleus cross sections

open access: yes, 2006
The Random Phase Approximation theory is used to calculate the total cross sections of electron neutrinos on $^{12}$C nucleus. The role of the excitation of the discrete spectrum is discussed.

Determining Urban Development Orientation Based on Air Pollution Diffusion Modeling from Thermal Power Plants, Case Study: Mashhad [PDF]

open access: yesتحقیقات کاربردی علوم جغرافیایی, 2023
There are several limiting factors to the development of cities. These factors lead cities to develop in certain directions. Air pollution as a major problem of metropolises can itself be considered as a limiting factor of urban development by urban ...
