The direct collisional interaction of magnetospheric particles with Io will lead to sputtering of atoms and molecules from the satellite into circum-Jovian space. The -•520-eV S (and -•260-eV O) ions composing the Io toms are the most effective agents for net sputter emoval of matter from the satellite. An incident flux of-•10 •ø cm -2 s -• is estimated to provide -•5 x 10 •ø S atoms cm -2 s -•...

Penelitian ini bertujuan mengkaji hubungan kekerabatan, waktu pisah, pasangan korespondensi fonemis, dan perubahan bunyi dalam bahasa Aceh Gayo. menggunakan metode penelitian kombinasi (pendekatan kuantitatif kualitatif) dengan menerapkan teknik leksikostatistik glotokronologi. Secara diperoleh kekerabatan antara Gayo adalah 43% yang dapat dikelompokkan kelompok keluarga. Hasil perhitungan glot...

Fowler, Greenstein, and Hoyle have proposed that the inner solar system was heavily irradiated during its formation. A consequence of this proposal is that sizable differences in meteoritic and terrestrial K'3⁄4K 'ø ratios are possible if the fraction of material which was irradiated was different in the two cases. The isotopic composition of potassium was measured by mass spectrometry for nine...

Nitrogen is an essential plant nutrient. It is the nutrient that is most commonly deficient in soils, contributing to reduced agricultural yields throughout the world. Nitrogen can be supplied to crops by biological nitrogen fixation (BNF), a process which is becoming more important for not only reducing energy costs, but also in seeking more sustainable agricultural production. Nitrogen fixing...

OBJECTIVES Repair of thoracic aneurysms (TA) involving the ascending, arch, and descending aorta results in substantial morbidity and mortality. This study evaluates outcomes with a two-stage elephant trunk (ET) technique. METHODS Two hundred and fifteen consecutive patients (pts) underwent total arch replacement using an ET (02/90-09/06). One hundred and thirty-nine pts (65%), group PC (plan...

Abstract This article describes the usage of partial interrogatives without wh such as And you went…? in French and Spanish, analyses variation between in-situ -Ø in-situ-wh -interrogatives went where? On basis an analysis -Ø-interrogatives a corpus spoken these are described particularly efficient means realizing information request. Due to fact that their use is bound contexts which request h...

This event-related potential (ERP) study examined the impact of phonological variation resulting from a vowel merger on phoneme perception. The perception of the /e/-/epsilon/ contrast which does not exist in Southern French-speaking regions, and which is in the process of merging in Northern French-speaking regions, was compared to the /ø/-/y/ contrast, which is stable in all French-speaking r...

Abstract Nanocellulose is an emerging material that needs to be well characterized control its performance during industrial applications. Gel point (Ø g ) a convenient parameter commonly used estimate the aspect ratio (AR) of cellulose nano/microfibers (CNFs/CMFs), providing critical information on nanofiber network. However, estimation requires many sedimentation experiments, tedious and time...
