We show that the Dual Borel Conjecture implies that d > א1 and find some topological characterizations of perfectly meager and universally meager sets.

Arid regions pose a serious problem for crop production by suppressing plant growth. The use of plant growth promoting rhizobacteria (PGPR) as bioinoculant may be promising to enhance the crop yield in arid conditions. In the present investigation, four strains of cultivable bacteria associated with the rhizosphere of Saccharum L. grown in arid region were isolated using N-free media. Assessmen...

Abstract Arid regions have deficient precipitation, understanding the sources and transportation of moisture for precipitation are crucial. This study examined major contributions global six arid regions, which classified as inland region (China-Mongolia) coastal (North Africa, West Asia, United States, South Africa Australia). Results indicated that, in originates mostly from ocean, is influen...

Nowadays, there is a large demand for nutrient-dense fruits to promote nutritional and metabolic human health. The production of commercial fruit crops becoming progressively input-dependent cope with the losses caused by biotic abiotic stresses. A wide variety underutilized crops, which are neither commercially cultivated nor traded on scale, mainly grown, commercialized consumed locally. Thes...
