Seed germination and seedling establishment in pistacia atlantica desf. and pistacia lentiscus l. under drought
(Russian Journal of Plant Physiology, 2023)The rehabilitation of degraded Mediterranean areas requires reintroduction of key-stone woody species. However, seed germination and seedling establishment for native species are poor. Germination behavior of Pistacia ... -
Seed priming with MeJa prevents salt-induced growth inhibition and oxidative damage in sorghum bicolor by inducing the expression of jasmonic acid biosynthesis genes
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)Salinity is one of the major detrimental abiotic stresses at the forefront of deterring crop productivity globally. Although the exogenous application of phytohormones has formerly proven efficacious to plants, their effect ... -
Seen and heard: new frontiers in child participation in family law proceedings in South Africa
(Nelson R Mandela School of Law, University of Fort Hare, 2009)This article examines the principle of child participation in a legal context, focusing first on the international and constitutional law framework, and thereafter on the principle as it has permeated the South African ... -
An SEIR model with infected immigrants and recovered emigrants
(Springer Science and Business Media Deutschland GmbH, 2021)We present a deterministic SEIR model of the said form. The population in point can be considered as consisting of a local population together with a migrant subpopulation. The migrants come into the local population for ... -
An SEIRS epidemic model with stochastic transmission
(Springer, 2017)For an SEIRS epidemic model with stochastic perturbations on transmission from the susceptible class to the latent and infectious classes, we prove the existence of global positive solutions. For sufficiently small values ... -
Selecting an appropriate method for expressing S locus F-box-S2 recombinant protein
(Elsevier, 2017)A single locus (S locus) including at least two linked genes (female and male determinants) genetically controls the gametophytic self-incompatibility (GSI) in apple, which has evolved to avoid self-fertilization. There ... -
Selection analysis identifies clusters of unusual mutational changes in omicron lineage ba.1 that likely impact spike function
(Oxford University Press, 2022)Among the 30 nonsynonymous nucleotide substitutions in the Omicron S-gene are 13 that have only rarely been seen in other SARS-CoV-2 sequences. These mutations cluster within three functionally important regions of the ... -
Selection of Clostridium spp. in biological sand filters neutralizing synthetic acid mine drainage
(Wiley, 2013)In this study, three biological sand filter (BSF) were contaminated with a synthetic iron- [1500 mg L-1 Fe(II), 500 mg L-1 Fe(III)] and sulphate-rich (6000 mg L-1 SO2/4-) acid mine drainage (AMD) (pH = 2), for 24 days, to ... -
Selection of diazotrophic bacterial communities in biological sand filter mesocosms used for the treatment of phenolic-laden wastewater
(Springer Verlag, 2013)Agri effluents such as winery or olive mill waste-waters are characterized by high phenolic concentrations. These compounds are highly toxic and generally refractory to biodegradation. Biological sand filters (BSFs) represent ... -
Selective electrodeposition of Co-Ni composites from synthetic quasi LiB NMC 532 cathode sulphate solutions using rotating plate potentiostatic electrowinning
(Elsevier B.V., 2024)The interest in recycling spent lithium-ion batteries (Li-ionB) has surged due to the rising demand for valuable metals (e.g., Co, Ni, Li and Mn) and concerns about environmental repercussions emanating from conventional ... -
Selectivity of oxygen evolution reaction on carbon cloth-supported δ-mno2 nanosheets in electrolysis of real seawater
(Molecules, 2023)Electrolysis of seawater using solar and wind energy is a promising technology for hydrogen production which is not affected by the shortage of freshwater resources. However, the competition of chlorine evolution reactions ... -
Selenium functionalized carbon for high dispersion of platinumeruthenium nanoparticles and its effect on the electrocatalytic oxidation of methanol
(Elsevier, 2013)Using selenium functionalized carbon as supports, platinumeruthenium nanoparticles were highly dispersed on the carbon surface, and showed improved electrochemical properties for methanol electrooxidation. The method ... -
Selenium-functionalized carbon as a support for platinum nanoparticles with improved electrochemical properties for the oxygen reduction reaction and CO tolerance
(Electrochemical Society, 2013)Using selenium-functionalized carbon as supports, platinum nanoparticles were uniformly dispersed on the carbon surface, and showed improved electrochemical properties for the oxygen reduction reaction. At the same time ... -
Self-assessment of final-year undergraduate physiotherapy students’ literature-searching behaviour, self-perceived knowledge of their own critical appraisal skills and evidence-based practice beliefs
(Health and Medical Publishing Group, 2016)BACKGROUND. Health professionals and new graduates alike are expected to be efficient in applying evidence-based practice. Research and evidencebased practice skills are taught in the research modules at university, but ... -
Self-care symptom-management strategies amongst women living with HIV /AI DS in an urban area in KwaZulu-Natal
(Oasis OpenJournals, 2010)People living with HIV and AIDS experience a number of symptoms such as fatigue, nausea and vomiting, fever and anxiety during the various stages of the illness. This has a negative effect on their quality of life. Women ... -
Self-catalytic growth of tin oxide nanowires by chemical vapor deposition process
(Hindawi, 2013)We report on the synthesis of tin oxide (SnO2) nanowires by a chemical vapor deposition (CVD) process. Commercially bought SnO nanopowders were vaporized at 1050∘C for 30 minutes with argon gas continuously passing through ... -
