Code Mixing Used by the Presenter on Visi Fm

This study deals with code-mixing used by presenters on VISI FM. The objectives of this study are to : (1) find out the forms ofcode-mixing, that are used by VISI FM's presenters. (2) find out the form of code- mixing that is dominantly used by VISI FM's presenter. This research applied descriptive quantitative method.The object of this study is presenter of VISI FM namely Deris and Lia. The tape recorder is used for collecting the data where the utterence of presenters were recorded while presenting that program.After collecting the data, the writer found that forms of code mixing occured in the presenters's utterances are code mixing in forms words, phrases, and sentences. Code mixing in form of word is dominantly used by male presenters namely Deris, where the percentage of the occurrence of code mixing in his utterances are 255 code mixing, where there are 29 code mixing in form of sentences, 92 code mixing in form of phrases, and 133 code mixing in form of words and code mixing in form of sentence is dominantly used by female presenter namely Lia where the percentage of the occurrence of code mixing in her utterances are 184 code mixing occured where there are 82 code mixing in form of sentences, 44 code mixing in form of phrases, and 58 code mixing in form of words.

Suppression of spin-state transition in epitaxially strained LaCoO_{3}

Epitaxial thin films of LaCoO_{3} (E-LCO) exhibit ferromagnetic order with a transition temperature T_c = 85 K, while polycrystalline thin LaCoO_{3} films (P-LCO) remain paramagnetic. The temperature-dependent spin-state structure for both E-LCO and P-LCO was studied by x-ray absorption spectroscopy at the Co L_{2,3} and O K edges. Considerable spectral redistributions over temperature are observed for P-LCO. The spectra for E-LCO, on the other hand, do not show any significant changes for temperatures between 30 K and 450 K at both edges, indicating that the spin state remains constant and that the epitaxial strain inhibits any population of the low-spin (S = 0) state with decreasing temperature. This observation identifies an important prerequisite for ferromagnetism in E-LCO thin films.Comment: 5 pages, 5 figures, submitted to Physical Review

Mineral nutrient status, some quality and morphological characteristics changes in peanut (Arachis hypogaea L.) cultivars under salt stress

Peanut (Arachis hypogaea L.) is considered to be one of the most important crops which thrive in newly reclaimed sandy soils as a leguminous crop of high nutritive value and a source of edible oil. Our study tested the effects of different salt levels on mineral nutrient partitioning (Na+, K+, Mg2+, Ca2+, P and N) and some quality (dry weight and leaf relative water content) and morphological (plant height, number of leaves) characteristics of peanut commercial cultivars. Four peanut cultivars (Mbiah, Ngondo, Pyrieur and Vanda) were used in this experiment. Three concentrations of salt solution including 50, 100 and 200 mM NaCl and the control (Wacquant nutrient solution) were used in irrigation. The pot experiment was arranged in completely randomized design with four replicates. The leaf relative water content (LRWC) provoked by the salinity in nutrient solution decreased from 85.08 to 83.43%, 87.82 to 85.30%, 85.81 to 78.20% and 85.90 to 79.70% in Mbiah, Ngondo, Pyrieur and Vanda cultivars respectively. The results showed that the salt stress reduced significantly (p<0.05) the plant height in Pyrieur cultivar from 40.49 to 21.45 cm, the number of leaves from 11.2 to 7.0, the dry weight of roots from 0.15 to 0.11 g Plant-1, the dry weight of stems from 0.37 to 0.15 g Plant-1 and the dry weight of leaves from 0.46 to 0.19 g Plant-1. Similar results were obtained in Vanda cultivar where the supply of nutrient solution with salinity reduced significantly (p<0.05) the plant height from 38.26 to 26.30 cm, the number of leaves from 12.5 to 7.5, the dry weight of roots from 0.14 to 0.03 g Plant-1, the dry weight of stems from 0.36 to 0.12 g Plant-1 and the dry weight oh leaves from 0.46 to 0.19 g Plant-1. The results also revealed that K+, Mg2+, Ca2+, P, N, K+/Na+ and Ca2+/Na+ uptake of peanut plant organs were significantly (p<0.05) reduced with increasing salinity in Pyrieur, Vanda and Mbiah except for total N accumulation in plant organs of Mbiah. The plant height, the number of leaves, the dry weight and the mineral nutrient uptake were not significantly (p>0.05) reduced under salt stress in Ngondo plant organs except at high salt-treated (200 mM NaCl). The Ngondo cultivar was observed to have relatively higher tolerance on average of all growth parameters and mineral nutrient status than others. This finding suggested that the Ngondo cultivar could be used to highlight the newly salt cultivated sandy soils in arid, semi-arid regions and similar environments across Cameroon.Key words: Arachis hypogaea, growth parameters, mineral nutrient, plant organs, salt stress

NPG–TRIS Thermal Storage System. Quantification of the Limiting Processes: Sublimation and Water’s Adsorption

The NPG–TRIS binary system (NPG = (CH3)2C(CH2OH)2 = 2,2-dimetyl-1,3-propanodiol; TRIS = NH2C(CH2OH)3 = 2-Amino-2-(hydroxymethyl)-1,3-propanediol) was intensively investigated as a thermal energy storage system, due to the reversibility of its phase transitions and their associated energy. An adapted methodology was applied to precisely quantify its sublimation tendency. Relevant thermochemical data were revisited and evaluated using some specific experimental procedures. We also determined that the widely accepted requirement of working in an inert atmosphere to avoid deviations due to hygroscopicity is not necessary. Nevertheless, to take advantage of the energetic properties of the NPG–TRIS system, closed containers will be required to avoid NPG losses, due to its quantitatively determined high sublimation tendency.This study was financially supported by the Basque Government (IT1301-19, IT1364-19) and through the Elkartek18 R&D program, by the University of the Basque Country UPV/EHU (GIU19/019), and by the Ministry of Science and Innovation of Spain (PID2019-106644GB-I00
