Introduction: The presence of sulfates on the surface of Mars was indicated by a strong Mg-S correlation in the fluorescence data obtained by the Viking landers [1]. Sulfates were subsequently identified as being present in the soil at the Pathfinder landing site at a concentration of ~ 10 % MgSO4 [2]. Data from the Opportunity rover indicates that sulfates of probable evaporite origin are pres...

we prove a strong convergence result for a sequence generated by halpern's type iteration for approximating a common fixed point of a countable family of quasi-lipschitzian mappings in a real hilbert space. consequently, we apply our results to the problem of finding a common fixed point of asymptotically nonexpansive mappings, an equilibrium problem, and a variational inequality problem for co...

Mucoadhesive chitosan microspheres of amlodipine besylate were prepared for nasal administration with the aim of avoiding the first pass effect. A series of batches of microspheres were prepared by simple emulsification crosslinking method to optimize parameters like external phase (mixture of heavy and light liquid paraffin in the ratio of 1:1), stirring rate (1200 rpm), dioctyl sodium sulfosu...

Bolaang Mongondow is located on the Eastern North arm of Sulawesi. This area a Neogene-aged magmatic arc composed plutonic and volcanic rocks that indicate mineralization-bearing host rocks. The study aimed to determine geological setting alteration based observations geochemical analysis. method used mapping, followed by laboratory studio data lithology this andesite, diorite, pyroclastic brec...

purpose: given that weight and body mass index (bmi) are considered as modifiable factors in osteoporosis, the present study aimed to examine the relationship of weight and bmi with bone mineral density (bmd) and bone mineral content (bmc) at the femur and lumbar vertebrae in perimenopausal women. methods: in this descriptive-correlational study, we measured the bone density of the femur and lu...

our civilization is based on metals, among other life supports. the existing ore deposits are becoming rapidly depleted by almost exponentially increasing demand and production and major new ore discoveries are needed. mineral exploration is supported by modern tools and scientific ideas, but geological characteristics of orebodies and their rock associations have still to be visualized.the tim...

Compared to natural waters, mine waters represent an extreme water type that is frequently heavily polluted. Although they have been traditionally monitored by in situ measurements of point samples taken at regular intervals, the emergence of a new generation of multispectral and hyperspectral (HS) sensors means that image spectroscopy has the potential to become a modern method for monitoring ...
