Nelson [2]. In this paper, we consider Ito’s integral with respect to the extended Wiener measure and extend Ito’s formula for Ito’s process. Because of doing the extension of Ito’s formula, we could treat stochastic differential equations in the sense of nonstandard analysis. In this framework, we need the nonstandardization of convolution again. It was not yet proved in the last paper, therefore we shall provide the proof.展开更多

Using SnCl4·5H2O and In as starting materials, the crystallites were characterized by XRD, TEM and BET. The effects of the conditions on the product were investigated. The results show that the phase of hydrothermal precursor obtained by hydrothermal process is related to the temperature of hydrothermal reaction, i.e., the phases are amorphous In（OH）3 in 160-180℃; In（OH）3 crystal in 200℃ and （In 1-x Snx）OOH crystal in 200-300℃. ITO nano-powders with hexagonal structure and average size of 65 nm are obtained by calcining the precursor derived from the hydrothermal process at 350-650℃. The BET of ITO crystal can reach 84.0234m2·g -1 .展开更多

Nursing care is enhanced by the nursing process, which outlines the nursing activities to be provided for a patient. Methods and Materials: A cross sectional design employing quantitative methods was conducted in Njombe RRH in December 2021. Quantitative data were collected from nurses and midwives from all wards by simple random sampling techniques using a sample-size calculator. SPSS version 26.0 was used to analyse data whereby a p-value of 0.05 was considered a decision mark for the significance of the result;Chi-square and Logistic regression respectively were used to find out the association and its strength between variables. Result: Majority of the respondents, 41 (85.4%), had inadequate knowledge and 33 (68.8%) found them people with a negative attitude to the nursing process. Significantly, there is an association between knowledge and clinical utilization (AOR 2.24;95% CI: 1.6 - 2.5;P 0.04), attitude and clinical utilization (AOR 4.32;95% CI: 1.8 - 3.7;P Conclusion: A knowledge gap in relation to the utilization of the nursing process and a negative attitude were noted to be associated significantly with the utilization of the nursing process among nurses and midwives. It is recommended on-job training, supportive supervision, and Value Clarification and Attitude Transformation (VCAT) are the best interventions to address the knowledge gap and negative attitudes respectively.展开更多

As a result of Eagle’s various studies, 4 out of every 100 patients showed that the styloid process was long. However only 4% of these cases are symptomatic [1]. Surgical traumas such as tonsillectomy or stylomandibular chronic irritation of the ligament, proc. of styloideusosteitis, ossifying periosteitis, tendinitis or mucositis why could it be [2]. The main symptoms are facial pain, dysphagia, sore throat, earache and headache. It may be unilateral or bilateral. The styloid process can be shortened through an intraoral or external approach.

文摘In this article, we give a new proof of the Itôformula for some integral processes related to the space-time Lévy noise introduced in [1] [2] as an alternative for the Gaussian white noise perturbing an SPDE. We discuss two applications of this result, which are useful in the study of SPDEs driven by a space-time Lévy noise with finite variance: a maximal inequality for the p-th moment of the stochastic integral, and the Itôrepresentation theorem leading to a chaos expansion similar to the Gaussian case.
