Quaternion-based Encryption/Decryption of Audio Signal Using Digital Image as Variable Key
Authors: ElSharkawy Magdy Ibrahim 
Published: October 2022

With the rapid growth of communication technology, cryptography plays a significant role in securing and verification of information exchanged via public communication channels. The current paper introduces a novel method for encrypting/decrypting audio signal using a selected digital image as a complicated key and cover for audio signal. Each sample of the audio signal is combined with the values of the three color components of a pixel fetched from the cover image yielding a quaternion number. The absolute value of this quaternion number is then transmitted and when received, the original value of the audio sample can be extracted using simple quaternion mathematics. A second level of complexity can be added to this approach by applying one of the well-known cryptographic techniques (symmetric or asymmetric). The suggested approach is implemented using Matlab simulation software and the generated audio signal is compared with the original one using some performance metrics. The obtained results show that the proposed approach is robust and more secure against cryptanalysis attacks.

Multidrug-resistant strains of , a significant hospital pathogen, have developed resistance to virtually all available antibiotics. Carbapenems antibiotics are among the most commonly used antibiotics against Acinetobacter infections, but they can be rendered ineffective by the metallo-beta-lactamase enzyme. In this study, bacteriophage isolated against producing was evaluated for its therapeutic potential in the rabbit pneumonia model.was isolated from the sputum and was speciated as per the standard microbiological techniques. Bacteriophage specific for producing from the sewage water. Pneumonia was introduced in the rabbits as per Esposito Pennington method and efficacy of the bacteriophage in resolving pneumonia was evaluated. For in-vivo experiments, five groups of rabbits were used including infection-free, phage control, bacteria-infected control, and the other two groups infected with and treated either with an antibiotic, colistin (2.5 mg/kg, twice a day intraperitoneally) or Acinetobacter phage (3×10 PFU/mL, given once through nebulizer). The experimental animals were monitored for 72 hours for mortality, and the surviving rabbits were killed for bacteriological and histopathological analysis In the infected group, pneumonia was developed within 48 hours, and 6/10 animals were dead after 72 hours. All the animals in the antibiotic group survived but showed signs of pneumonia, and there was up to 4 log CFU/g±0.24 reduction in the bacterial count. In phage treated group, all the animals survived at the end of 72 hours and all the animals were healthy with no signs of pneumonia. The experiment showed new insights into the application of bacteriophage through nebulization, a non-invasive method of phage delivery to rescue rabbits from pneumonia caused by -producing .

Despite the advances in healthcare setup, Community Acquired pneumonia still continues to be one of the major causes of morbidity and mortality among the hospitalised, especially the elderly population. Knowledge about the distribution of the disease, susceptible population, risk factors, mortality and morbidity outcomes makes it easy for the effective management of the affected individuals. Even though we have enough data on worldwide distribution and outcome of CAP, similar studies in Indian setup are few. Considering the fact that the change in environment, population characteristics and difference in clinical practices can hugely influence the outcome of CAP, it was found necessary to conduct this study.: To understand the demographic profile of patients, to identify the main symptoms and risk factors and to find out the outcome of patients admitted with CAP in a tertiary health care centre in Thrissur.Retrospective study by collecting the details of patients hospitalized with CAP in the past one year by going through their medical records.The incidence of CAP was found to be steadily increasing with age, more in males with productive cough being the most common symptom. While in majority of cases no organisms were isolated, the ones which had an identified causative organism were mainly bacterial. Maximum cases occurred in monsoon season and the mortality rate was 2%.

Authors: Amado Andreia , Pimenta Joana , Queirós Tatiana , Leite Mariana , Tavares Amélia , Cardoso João , Gandra Lurdes , Oliveira Manuel 
Published: October 2022

Introduction: Lower preoperative hemoglobin (H), albumin (A), lymphocyte (L) and platelet (P) score (HALP) has been identified as a predictive factor in LACC to categorize patients with higher risk of poor outcome. Therefore, it is important to identify biomarkers available in clinical practice that can predict survival and patient’s prognosis. Our aim is to evaluate preoperative HALP score and its prognostic value.

Materials and Methods: Our retrospective study included patients with LACC submitted to oncologic resection between January 2015 to December 2019 in our institution. LACC included stages II and III adenocarcinoma. HALP score was calculated as H (g/L) x A (g/L) x L (/L) / P (/L). A cutoff value was determined by ROC curve analysis and patients were divided accordingly into two groups (low and high HALP) to compare cancer-specific survival, through Kaplan-Meyer curve.

Results: In our study, 127 patients were included. The mean age was 70,7 ± 11,9 years and 67 (52,8%) were male. Stage II incorporated 65 patients (51,2%) and stage III 62 (48,8%). The median follow-up time was 37 months. The HALP cutoff value estimated was 22,5. Age ³ 65 years, right-sided tumor, surgical reintervention and cancer-specific survival were associated with a lower HALP scores (p=0,002; p=0,004; p=0,008 and p=0.001, respectively).

Conclusion: Nutritional and systemic inflammation status are extremely important in colon cancer prognosis. Serum biomarkers, such as HALP score could easily identify patients with a higher risk of poor outcome. Thus, this prognostic index may be useful as a clinical predictor of survival for LACC patients.

Published: October 2022

The effect of earthquakes on the stability of the subway station and ground motions of surrounding rock masses, plays a key role in the seismic design of the subway station to avoid severe damage to subway station itself and adjacent structures. Most of the reported cases in the literatures on the effect of earthquake on ground motions focused on the ground motions without considering underground structures. In this study, the effect of earthquakes on the stability of the subway station, and ground motions of surrounding rock masses were investigated by using the Flac3d. The ground acceleration and safety factor of tunnel lining were highlighted. The results of the numerical analysis indicated the presence of a subway station has a great influence on ground motions, especially for the vertical ground acceleration. The ground acceleration increases with the decrease of buried depth. The amplification factor of ground acceleration is about 1.42. It exists an amplification region above the subway station with the width of 15 m. The safety factor of tunnel lining in subway station has a significant decrease in the maximum decrease rate of 67 %. The safety factor of tunnel lining except for tunnel crown and bottom changes periodic. Ground acceleration will induce extrusion or detach between surrounding rock masses and tunnel lining, and the direction of ground acceleration has a great influence on distribution of safety factor. The side wall and arch feet of tunnel lining is the most unfavorable part. Special attention should be paid to the side wall and arch feet of the subway station during seismic design.

Published: October 2022

The harmonic response under the in plane and out of plane driving force separately and model analysis of the widely used SCM-PIT probe were carried out in the consideration of the typical piezoresponse force microscopy working condition by finite element method. It is shown that there are symmetric modes of the resonance at 68, 408, 1139, 2244 kHz, and antisymmetric modes at 646, 1020, and 3077 kHz in the first seven eigenmodes. The symmetric modes of the harmonic response are verified by the frequency sweep method from the piezoresponse phase signals experimentally. It is also revealed that different driving frequencies should be used in the resonance-enhanced PFM imaging in the consideration of the domain structures. The driving frequency of 68, 408, 1139, 2244 kHz should be preferred in the resonance-enhanced PFM imaging of the out of plane domains, while the driving frequency of 646, 1020 and 3077 kHz should be used for the imaging of in plane domains in order of achieved the best resonance-enhanced effect.

Authors: Li Zhanfu , Tong Xin , Xia Huihuang , Yu Luojian 
Published: October 2022

We investigated the movement of particles in screening process over the sieve plate of a linear vibrating screen using the Discrete Element Method (DEM). The behavior of particles which is affected by a series of vibrational parameters including amplitude, frequency and vibration direction angle determining screening performance. This paper centers on particles looseness by analyzing the looseness coefficient and looseness rate. The relationships between the looseness coefficient, looseness rate and vibration parameters were profoundly discussed. Mathematical models relating looseness coefficient to time were established using the least squares method. An experimental platform which combines high-speed camera system with experimental prototype of vibrating screen was designed. The research made a more in-depth investigation of particles’ movements and analysis of particle looseness. Physical experiments were used to verify the reliability of simulation results. Finally, we would come into the following conclusions: high frequency and large amplitude make particles obtain more energy to be active and the average distances among particles get larger slowly. On the contrary, at low frequency and amplitude, the looseness coefficient and looseness rate were relatively low. When the amplitude approaches 2.7 mm, the frequency is about 34 Hz and the vibration angle is around 42 degrees, the looseness ratio produces better performance. The paper offered insights to the design and manufacturing of vibrating screen.

Published: October 2022

Abstract
In this study, the groundwater potential zones in Baringo County (Kenya) were identified using an integrated approach of Remote Sensing-Geographic Information System (RS-GIS) and Analytical Hierarchy Process (AHP) techniques, and thematic layers of rainfall, slope, lithology, soil type, land use, drainage density and lineament density. The data were validated using borehole yield and fluoride data obtained from boreholes in the area. Using RS-GIS-based methods to identify potential groundwater zones is more convenient and less expensive compared with the conventional methods. Rainfall, lithology, soils and land use/land cover were found to be the most significant factors influencing groundwater with weighted values of 31, 24, 18 and 10% respectively. The very good, good and poor potential zones covered 0.39, 65.33 and 34.27% area coverage of the study area respectively. Low yield boreholes were found in the poor groundwater potential zones and vice versa. Moderate yield boreholes were found in the good groundwater potential zone. The majority of the boreholes with acceptable fluoride concentration was found in the good groundwater potential zones, while those with high fluoride concentration levels were found in the poor groundwater potential zone. Generally, from this study, it can be concluded that remote sensing and GIS in conjunction with AHP are important tools in monitoring and evaluating groundwater resource potential areas.

Background
Studies that address the changing characteristics of diseases are of great importance for preventing and controlling the occurrence and development of diseases and for improving health. However, studies of the epidemiological characteristics of noncommunicable diseases (NCDs) and malignant tumors (MTs) of the residents in Guiyang, China, are lacking.

Objective
The aim of this study was to evaluate the prevalences of NCDs and MTs in residents of Guiyang, Guizhou Province, China, and analyze differences among ages, genders, and regions.

Methods
A multistage stratified cluster sampling method was used. Based on the inclusion and exclusion criteria, 81,517 individuals were selected for the study. Of these, 77,381 (94.9%) participants completed the study. Structured questionnaires were used to collect information on demographic characteristics, NCDs, and MTs. The chi-square test (with 95% confidence intervals) was used to analyze differences in disease prevalence among genders, ages, and geographical regions.

Results
The major chronic NCDs of Guiyang residents are obesity, hypertension, and diabetes. MTs in women are mostly breast cancer, cervical cancer, and endometrial cancer, whereas in men, MTs are mainly lung cancer, rectal cancer, and gastric cancer. The prevalences of hypertension and diabetes in women are higher than in men, but the prevalences of lung cancer and gastric cancer in men are higher than in women. The epidemiological characteristics of individuals in different life stages are dissimilar. In terms of regional distribution, the prevalences of the above diseases in the Baiyun and Yunyan districts of Guiyang are relatively high.

Conclusions
Several NCDs (obesity, hypertension, and diabetes) and MTs (women: breast cancer, cervical cancer, and endometrial cancer; men: lung cancer, rectal cancer, and gastric cancer) should be the focus for the prevention and control of chronic diseases in the future. In particular, the Baiyun and Yunyan districts of Guiyang are the important regions to emphasize.

Published: October 2022

The application of rukhṣah in prayer during the Covid-19 pandemic requires a deeper understanding so that the application of rukhṣah is truly implemented in accordance with the corridors that have been determined by Islamic law. Researchers found that the application of rukhṣah in prayer has been carried out in all areas affected by the pandemic even though in some areas they did not take rukhṣah in prayer. However, the mind will be able to think well about the problems of society in accordance with the principles of maqashid sharia, so that it still prioritizes taking rukhṣah rather than forcing the will. The policy on easing congregational prayers, eliminating Friday prayers and physical distancing for congregational prayers carried out by the government and the MUI is an effort to prevent the spread of COVID-19 which leads to the achievement of maqashid sharia so that it provides benefits even in an emergency. The research method used is library research and is qualitative in nature. Sources of data used in this study sourced from primary and secondary data. The results of this study are that it is the ability to cover the genitals for children as a form of caution to avoid unwanted things. Keywords:Rukhṣah; Prayer; Covid-19; Maqashid Shariah
