Assessment on the effects of potting mixtures on germination and growth of Moringa oleifera (LAM) seedlings in Sudan savanna ecology zone of Nigeria

This study was carried out in the Forestry nursery, Audu Bako College of Agriculture  ambatta, Kano-Nigeria. The aim was to evaluate seed germination and the growth rates of Moringa oleifera (Lam) in three (3) different growth media; to determine the best growth medium to raise Moringa seedlings; and to determine which of the growth medium support vigorous and early growth for Plantation establishment in Sudan savanna ecology of Nigeria. The different soil media were: top soil, river sand and cow dung manure (treatment A); top soil, river sand and poultry manure (treatment B) and top soil and river sand (treatment C). Seeds of M. oleifera(Lam) tested for viability by floatation method were planted in different soil Media and replicated three times. The experiment was arranged in a Completely Randomized Design and watering was carried in all the treatments daily. The germination and growth of the seedlings were assessed for twelve weeks. Parameters measured were: germination rates, seedlings height, leaflets width and length, and leaflet numbers. Data were subjected to ANOVA and results showed that there was significant difference on parameters assessed on the 10th day (F=4.56, P=0.01 P<0.05) and 30th day (F=3.42, P=0.04 P<0.05) among the three treatments in terms of height (cm) but on the 20th day, there was no significant variation (F=1.02, P=0.37 P>0.05) in height of the seedlings among the treatments. Therefore, germination and early growth rate of Moringa oleifera seeds in treatment C (topsoil & river sand) demonstrated better growth potential on the average, than seeds planted in treatment A and B, respectively.Key words: Germination; Moringa oleifera (lam); Treatment; Seedlings; Media/medium; Parameter

Modelling modulation perception : modulation low-pass filter or modulation filter bank?

In current models of modulation perception, the stimuli are first filtered and nonlinearly transformed (mostly half-wave rectified). In order to model the low-pass characteristic of measured modulation transfer functions, the next stage in the models is a first-order low-pass filter with a typical cutoff frequency of 50 to 60 Hz. From physiological studies in mammals it is known that many neurons in, e.g., the inferior colliculus, show a bandpass characteristic in their sensitivity to amplitude modulation. Results from psychophysical studies of modulation masking also suggest some kind of bandpass analysis of modulation frequencies. Results of two experiments on modulation detection that allow discrimination between models incorporating a low-pass filter and those using a modulation filterbank are presented. In the first experiment, modulation detection thresholds were measured for noise carriers of bandwidths between 3 and 6000 Hz. In the second experiment, modulation detection for a sinusoidal carrier was measured in the presence of interfering modulation components with a bandpass characteristic in the modulation spectrum. The results from these experiments could not be simulated by a model including a modulation low-pass filter, but were successfully simulated by a model using a modulation filterbank

Evaluating Behavioral Health Service Need for Sexual and Gender Minorities: A Community-Based Qualitative Study

The LGBTQ community experiences mental health challenges, such as anxiety, depression, and substance use disorders, at rates higher than heterosexual and cisgender counterparts. Given these disparities in mental health, it is crucial that the LGBTQ population has access to mental health services. However, LGBTQ individuals face barriers to accessing mental health care due to service affordability, availability, and/or lack of LGBT-inclusivity. A Place to Nourish your Health (APNH), formerly known as AIDS Project New Haven, has historically provided care to those in New Haven who live with HIV and AIDS. APNH is now seeking to re-define itself as an organization by expanding services to support those experiencing stigma related to gender identity, sexual orientation, addiction, and mental health. Thus, to aid APNH in their service expansion to stigmatized populations, we performed a qualitative community needs assessment in the greater New Haven area to inform where APNH’s priorities should lie in their expansion of services. Findings provided insight into the current mental health landscape of New Haven’s LGBTQ community and led to reccomendatios regarding APNH\u27s expanion of behavoral health services.https://elischolar.library.yale.edu/ysph_pbchrr/1024/thumbnail.jp

Vorratsschutz im Ökologischen Landbau: Entscheidungshilfe durch das Computerprogramm VOEL 1.0

VOEL 1.0 is a decision-support software for the protection of organic stored-products that was developed for store-keepers, farmers and pest control specialists in Ger-many. Most of the information given applies to all Central European countries, except for some legislative aspects concerning registration, which are specific for Germany. The program contains a decision-support module for monitoring and control of stored product pest, an encyclopedia on pests and beneficial organisms, a key for the deter-mination of these organisms, information on registered products for stored product protection in Germany, a data bank where literature concerning associations of pests and beneficials can be retrieved, a list of references on stored product protection in general and several original papers on stored-product protection

Structural properties of Co2TiSi films on GaAs(001)

Co2TiSi films were grown by molecular beam epitaxy on GaAs(001) and analyzed using reflection high-energy electron diffraction, and electron microscopy. In addition, X-ray diffraction was combined with lattice parameter calculations by density functional theory comparing the L21 and B2 structures and considering the influence of non-stoichiometry. Columnar growth is found and attributed to inhomogeneous epitaxial strain from non-random alloying. In films with thicknesses up to 13 nm, these columns may be the origin of perpendicular magnetization with the easy axis perpendicular to the sample surface. We found L21 and B2 ordered regions, however the [Co]/[Ti]-ratio is changing in dependence of the position in the film. The resulting columnar structure is leading to anisotropic B2-ordering with the best order parallel to the axes of the columns

Evidence of Sulfur Non-Innocence in [CoII(dithiacyclam)]2+-Mediated Catalytic Oxygen Reduction Reactions

In many metalloenzymes, sulfur-containing ligands participate in catalytic processes, mainly via the involvement in electron transfer reactions. In a biomimetic approach, we now demonstrate the implication of S-ligation in cobalt mediated oxygen reduction reactions (ORR). A comparative study between the catalytic ORR capabilities of the four-nitrogen bound [Co(cyclam)]2+ (1; cyclam=1,5,8,11-tetraaza-cyclotetradecane) and the S-containing analog [Co(S2N2-cyclam)]2+ (2; S2N2-cyclam=1,8-dithia-5,11-diaza-cyclotetradecane) reveals improved catalytic performance once the chalcogen is introduced in the Co coordination sphere. Trapping and characterization of the intermediates formed upon dioxygen activation at the CoII centers in 1 and 2 point to the involvement of sulfur in the O2 reduction process as the key for the improved catalytic ORR capabilities of 2
