a r t i c l e i n f o a b s t r a c t In the context of sample evidence alone, the high-alumina (HA) basalts appear to be an unique, and rare variety of mare basalt. In addition to their distinct chemistry, radiometric dating reveals these basalts to be among the oldest sampled mare basalts. Yet, HA basalts were sampled by four missions spanning a lateral range of ∼2400 km, with ages demonstrat...

The effect of organic manure and chemical fertilizers on vegetable crops and soil properties in the radish-stem amaranth-Indian spinach cropping pattern was studied in a homestead area of Gazipur district in Bangladesh. There were eight treatments poultry manure (PM) 5 t ha (T1), cowdung (CD) 10 t ha -1 (T2), household waste (HW) 10 t ha -1 (T3), PM 2.5 t ha -1 + reduced RDF (recommended dose o...

in order to study the effect of planting pattern and herbicide application on corn (zea mays l.) grain yield and weeds control, an experiment was carried out in 2007 at varamin research station of plant protection research institute. the experimental design was a randomized complete block in a split plot arrangement with 4 replications. experimental factors consisted of planting patterns at 4 l...

The study has found that on average for two years of research, the yield soft winter wheat was highest at sowing rates 5 million/ha – 5.53 t/ha. Under 4 indicator made 5.28 t/ha or only % less compared to rate million/ha. Sowing increase 8 reduced grain by 3–5 %. In addition, stability index high 0.95–0.98. varied from 4.82 5.59 in more favorable 2021, and 2020 4.56 5.47 depending rate. Increas...

Black polyethylene film mulches affect the activity of some nematicides (1, 2, 3, 5, 6, 7, 8, 9). Other mulches also may influence the results of fumigat ion tests; for example, hay mulches, cause the soil to remain cooler (8). Salt-hay mulches are used by strawberry growers, many of whom fumigate. Mulches of grass clippings, wood chips, or leaf mold are used by homeowners. Clear plastic mulche...

We compared the effects of adoptively transferred Th cell clones specific for the influenza hemagglutinin (HA), matrix (M), or nucleoprotein (NP) on the antibody response of nude mice infected with A/PR/8/34 influenza virus. We show that the production of antibodies to the HA absolutely requires the presence of virus-specific Th cells. Further, transfer of a Th clone specific for the internal p...

in order to improve the efficiency of irrigation systems and investigate their impact on the pest population levels, furrow and sprinkler irrigation systems were compared in sugar beet fields. in this study, three different fields were chosen and irrigated by one of the furrow, classic and center pivot irrigation systems.  in each field, 20 plots were randomly selected of which 10 plots were ma...

In vitro studies have suggested that tolerance induction (i.e., anergy) is associated with an inability of T cells to proliferate vigorously upon Ag recognition. In vivo, the relationship between T cell proliferation and tolerance induction is less clear. To clarify this issue, we have been studying a model system in which naive CD4+ T cells specific for the model Ag hemagluttinin (HA) are adop...
