Application of Modified Nanocellulose with 2-aminopyrimidine as a New Sorbent for Separation and Determination of Trace Amounts of Nickel Ions in Human Blood and Urine

In the present study, trace amount of nickel (II) ions in real samples has been separated, preconcentrated and determined by a synthesized nanocomposite. Our suggested nanocomposite was prepared by immobilization of 2-aminopyrimidine on nanocellulose. The properties of nanocomposite were characterized by TEM, TGA, elementalanalysis CHNS, EDS, and BET techniques. The effective factors such as pH, nanocomposite amount, extraction time, eluent type, ionic strength and sample volume were optimized for quantitative determination of nickel (II) ions. The linear range of the calibration graph was between 5 and 500 ng mL−1 with limit of detection (LOD) 2.33 ng mL−1. Relative standard deviations (RSD) were 2.33%. Modified nanocellulose was used for measurement of the trace amounts of Ni (II) ions in the real samples such as human blood and urine with suitable fallouts

Evaluating the effect of structural dimensions on the successful implementation of strategies in Payam-e-noor University of Iran

This study aims to assess the relationship between structural dimensions of organization including centralization, complexity and formalization on one side and strategy effectiveness on the other side. Structural dimensions are determined based on Robbins theory, and each of them is considered as independent variables of research. Strategy effectiveness, which includes achieving strategic goals or successful implementation of strategies are the independent variable of the research, based on Noble’s strategy implementation model. One primary thesis and three secondary these are defined. This is a descriptive research of two variable correlation. The target population includes 600 senior managers of Payam-e-noor university around the country, including staff administrative managers, province and unit headmasters, of Iran at the time of data collection. Simple random sampling is used, with sample size of 120. Library resources are used for theoretical foundation data collection and note-taking. Questionnaires are used to collect data and evaluate research theses. Inferential Statistics and Pearson correlation coefficient are used to analyze the research theses. The first two theses are confirmed, at 95% and 99% respectively, but the third thesis is rejected based on the collected data. Therefore, based on this study, complexity and formalization have respectively inverse and direct effect on strategy effectiveness, but centralization does not affect strategy effectiveness in Payam-e-noor University

A fractional number based labeling scheme for dynamic XML updating

Recently, XML query processing based on labeling schemes has been proposed.Based on labeling schemes, the structural relationship between XML nodes can be determined quickly without the need of accessing the XML document.However, labeling schemes have to re label the pre-existing nodes or re-calculate the label values when a new node is inserted into the XML document during the update process.In this paper, we propose a novel labeling scheme based on fractional numbers.The key feature of fractional numbers is that infinite number of fractional numbers can be inserted between any two unequal fractional numbers.Therefore, the problem of re-labeling the pre-existing nodes during the XML updating can be solved if the XML nodes are label by the fractional numbers

Controlling label size increment of efficient XML encoding and labeling scheme in dynamic XML update

Problem statement: In order to facilitate XML query processing, labeling schemes are used to determine the structural relationships between XML nodes. However, labeling schemes have to reliable the existing nodes or recalculate the label values when a new node is inserted into the XML document during XML update process. EXEL as a labeling scheme is able to remove relabeling for existing nodes during XML update process. Also, it is able to compute the structural relationship between nodes effectively. However, for the case of skewed insertions where nodes are always inserted at a fixed place, the label size of EXEL scheme increases very fast. Approach: This study discussed how to control the increment of label size for the EXEL scheme. In addition, EXEL does not consider the process of deleting labels. We also study how to reuse the deleted labels for future label insertions. Results: We proposed an algorithm which is able to control the label size increment. Conclusion: It required less storage size to store the inserted binary bit string and thus can improve query performance

Multiple Congenital Anomalies in a Preterm Neonate with G6PD Deficiency from Consanguineous Parents

Introduction: Congenital anomalies can be defined as structural or functional disorders, including metabolic disorders. The prevalence of congenital anomalies is not high. Case Presentation: We would like to present a 34-week- preterm neonate with glucose-6-phosphate dehydrogenase deficiency who was born with several fetal anomalies from consanguineous parents. Mother had a twin-birth pregnancy which one of twins died because of lung hemorrhage and the second twin was born with multiple anomalies four fingers in both hands, short legs attached to the pelvic bone, and absence of tibia, fibula, and ankle bones. Hemimelia, which was mostly known as the congenital deformity and a type of phocomelia, is extremely rare. To detect most of these types of anomalies, magnetic resonance imaging, radiography, ultrasound, and computed tomography scan can be used. Conclusion: Congenital anomalies are the cause of many infants' deaths. To detect most of these types of anomalies, MRI, radiography, ultrasound, and computed tomography (CT) scan can be used

A model for brand equity determination using structural equations modeling

A variety of methods for different purposes have been used to express the concept of brand equity. It is a noticeable value of brand, which makes the customer pay higher for the product with a brand comparing with identical product without that brand. Financially speaking, brand equity is an asset for the organization as it generates cash flow and profit in the future. The factors in brand equity must, therefore, be identified within financial and non-financial framework. By indicating the variables and the indices and consulting with the academic experts in marketing, brand, and accounting the results of structural equations modeling (SEM) revealed that significance level between brand equity and financial variables was 4.82 (>1.96). That is, the relationship between brand equity and financial variable were significant at %99. Regarding the relationship between brand equity and marketing variables, the significant level was 4.25 (>1.96) and thus the relationship was significant at %99. The results can be used as practical guideline for the stakeholders and owners of brands and also helpful for successful management of brand value

Assessing the water-energy-food nexus and resource sustainability in the Ardabil Plain : a system dynamics and HWA approach

Ardabil Plain, which holds significant political and economic importance in agricultural production in Iran, has faced various challenges including climate change, economic sanctions, and limited access to global trade. Ensuring food security has become a key priority for the region. The main objective of this research is to identify a suitable crop for this critical region with regard to future climate change conditions. This study employs a new framework of the system dynamics model (SDM) and the Hybrid Weighted Averaging (HWA) method to assess the Water–Energy–Food (WEF) nexus and resource sustainability in the Ardabil Plain under different climate change scenarios (RCP 2.6, RCP 4.5, and RCP 8.5). The research addresses current and future water challenges, emphasizing the need for additional energy and selecting optimal crops. Using the SDM, the study analyzes the impact of water supply fluctuations on agriculture, economic gain, and energy consumption from 2021 to 2050. The results indicate that barley is the most suitable crop for the Ardabil Plain in the near future, based on the overall ranking derived from the HWA method, which is as follows: barley > wheat > soybeans > potatoes > pears. The study highlights the significant challenges in energy supply for agriculture due to declining water levels and the increased force required by pumps to supply water to farms. These findings provide valuable insights for policymakers and stakeholders to make informed decisions in addressing water scarcity and rising energy demands in the Ardabil Plain

Post-Cardiac Injury Syndrome (Dressler Syndrome) Following Atrial Septal Defect (ASD) Repair: A Case Report

Dressler syndrome is a type of secondary pericarditis that can be accompanied by pleural effusion or pericardial effusion resulting from injury of the pericardium or heart tissue. A 33-year-old male was admitted to the emergency department with pleuritic chest pain radiating to both shoulders and fever. Two months before the admission, the patient underwent traditional open-heart surgery with median sternotomy and pericardiectomy for atrial septal defect (ASD) closure. Blood tests showed elevated acute phase reactants (leukocytosis, high erythrocyte sedimentation rate, and C-reactive protein). Left-sided pleural effusion was revealed on chest CT scan. Diagnosis of Dressler syndrome was established. The patient’s pleuritic chest pain and shoulder pain improved clinically with a short course of colchicine. Although Dressler syndrome is rarely seen, it should be considered in the differential diagnosis of pleuritic chest pain. Special attention should be paid to Dressler’s syndrome because pericarditis can develop following cardiac surger

A dynamic compressed accessibility map for secure XML querying and updating

By specifying a fine-grained access control on the XML data, an accessibility map is required to determine the accessibility of XML nodes for a specific subject (e.g. user or role) under a specific action (e.g. read or write). In the recent years, several research works have been done to reduce the overall storage cost of accessibility map with rapid determination of accessibility of XML nodes at runtime but there is no effort to implement the accessibility map in a compact format for dynamic environment where the accessibility of XML nodes can be updated frequently. In this paper, we propose a Dynamic Compressed Accessibility Map called DCAM to implement the accessibility map in a compact format which can be used in dynamic environment. Moreover, we suggest an efficient lookup method to determine the accessibility of XML nodes by labeling the authorization nodes in the DCAM with the dynamic XML labeling scheme. We also propose an efficient method to accelerate the process of checking the access authorizations for a set of XML nodes retrieved from the XML query processor when the access locality among the XML nodes in the XML tree is high. Besides, we define a set of constraints on the process of XML updating in order to maintain the DCAM in a compact format with minimum maintenance cost. The experimental results demonstrate that the DCAM is more efficient in both the space and time requirements for secure XML querying and updating
