Soft public key cipher

Encryption in general is the process of keeping up the secrecy of data (both fixed and versatile) utilizing programs that can Convert and make an interpretation of that data into codes so that whenever got to by unapproved people doesn't They can comprehend anything since what appears to them is a blend of images, numbers and unlimited characters, the file is encrypted And decryption by password, which must be known to both parties (sender and receiver) This is called With symmetric encryption, Decryption means decryption. The quality and viability of encryption rely upon two key factors: the algorithm, and the key length evaluated by Bit, the higher the bit, the greater the security and difficulty of decrypting. The concept of soft set was studied and applied on the public key cryptography like simple Knapsack and Trapdoor Knapsack ciphers. Significant results were presented that was the measure of the evaluate encryption using the SNR and PSNR

Improving chemical, rheological and sensory properties of commercial low-fat cream by concentrate addition of whey proteins

The present study was conducted to determine the effect of whey protein concentrate (WPC) addition on the commercial low-fat cream's chemical, rheological and sensory properties. WPC was added to the low-fat cream (10% fat)   in ratios of 1.0, 2.5, and 5.0% to represent the treatments C1, C2, and C3, respectively.In addition, a fat-rich, positive control treatment (C +) with a fat percentage of 30% and a negative low-fat control treatment (C-) with a fat percentage of 10% were investigated without adding WPC. Chemical tests were carried out, including the percentage of moisture, protein, fat, carbohydrates, total acidity, and pH, as well as rheological tests that included; hardness, springiness, and Cohesiveness. Also, a sensory evaluation was conducted. The results showed a decrease in the moisture percentage of the added treatments with the increment of the added WPC quantity. Also, a decrease in the fat percentage and pH of the WPC addition treatments was observed, combined with an increment in the percentage of protein, carbohydrates, ash, and total acidity. Regarding the microbiological properties, no bacterial or mycological contamination was observed during the manufacturing and storage periods. The results also showed the improvement of rheological and sensory characteristics by increasing the percentage of WPC addition compared with the positive and negative control treatments. The present study would be helpful in the production of low-fat cream fortified with whey proteins with high nutritional value

Impact of multiscale dynamical processes and mixing on the chemical composition of the upper troposphere and lower stratosphere during the Intercontinental Chemical Transport Experiment–North America

We use high-frequency in situ observations made from the DC8 to examine fine-scale tracer structure and correlations observed in the upper troposphere and lower stratosphere during INTEX-NA. Two flights of the NASA DC-8 are compared and contrasted. Chemical data from the DC-8 flight on 18 July show evidence for interleaving and mixing of polluted and stratospheric air masses in the vicinity of the subtropical jet in the upper troposphere, while on 2 August the DC-8 flew through a polluted upper troposphere and a lowermost stratosphere that showed evidence of an intrusion of polluted air. We compare data from both flights with RAQMS 3-D global meteorological and chemical model fields to establish dynamical context and to diagnose processes regulating the degree of mixing on each day. We also use trajectory mapping of the model fields to show that filamentary structure due to upstream strain deformation contributes to tracer variability observed in the upper troposphere. An Eulerian measure of strain versus rotation in the large-scale flow is found useful in predicting filamentary structure in the vicinity of the jet. Higher-frequency (6–24 km) tracer variability is attributed to buoyancy wave oscillations in the vicinity of the jet, whose turbulent dissipation leads to efficient mixing across tracer gradients

Temporomandibular Joint Ankylosis as a Complication of Neonatal Septic Arthritis : Report of two cases

Temporomandibular joint (TMJ) ankylosis as a complication of neonatal septic arthritis is rarely reported in the literature. We report two clinical cases of unilateral TMJ ankylosis occurring in paediatric patients subsequent to neonatal septic arthritis. The first case was a 15-month-old male infant who presented to the Sultan Qaboos University Hospital, Muscat, Oman, in May 2010. According to the published English scientific literature, he is the youngest person yet to be diagnosed with this condition. The second case was a five-year-old female who presented to the Al-Nahda Hospital, Muscat, Oman, in October 2011. Both cases presented with facial asymmetry and trismus. They subsequently underwent gap arthroplasty and interpositional temporalis muscle and fascia grafts which resulted in an immediate improvement in mouth opening. Postoperatively, the patients underwent active jaw physiotherapy which was initially successful. Both patients were followed up for a minimum of two years following their surgeries

Maxillary Artery Pseudoaneurysm as a Complication of Maxillofacial Injuries: Report of three cases and literature review

Traumatic maxillary artery pseudoaneurysm is an uncommonly reported complication in the field of oral and maxillofacial surgery. It is usually discovered incidentally, either early after trauma or weeks-to-months later. Quick recognition and prompt management are essential to avoid devastating consequences. In this paper, we report three uncommon cases of maxillary artery pseudoaneurysm recognised during the surgical management of maxillofacial injuries in Muscat, Oman. All cases presented as sudden brisk bleeding during the intraoperative surgical repair and were subsequently diagnosed and successfully managed by endovascular embolisation with platinum coils. This case report highlights the clinical presentation, diagnosis and management of maxillary artery pseudoaneurysm, in addition to a brief review of the literature.Keywords: Maxillofacial Injuries; Maxillary Artery; Pseudoaneurysm; Mandibular Condyle; Angiography; Therapeutic Embolization; Case Report; Oman

Seminal fluid; the Natural Guard of Seminal DNA

The ability of foreign DNA to be introduced into the sperm cells faces many problems. These problems have been emerged from the existence of some inhibitory factors available in the seminal fluid. Add to that, other several factors are involved in this internalization. The purpose of this review is to evaluate the protective or interactive roles of these seminal fluid proteins in the process of foreign DNA internalization into the head of the sperm. The ability of foreign DNA to be internalized inside sperm cell is become obvious before more than four decades (Brackett et al., 1971). But, the mechanism by which this foreign DNA has the ability to do so is still under debate. However, several papers described certain factors involved in this process. Thus, in order to describe the mechanism of sperm transfection by exogenous DNA, it is necessary to understand the following natural factors that are playing main roles in this scene and they include; inhibitory factor I (IF1), seminal fluid DNase, DNA binding proteins (DBPs), CD4, major histoincompatibility complex class II (MHCII), topoisomerase type II (TOPO II) and reverse transcriptase (RT). They can be further classified into three main groups. The First group is represented by two factors found in seminal plasma; IF1 and DNase, this group is responsible about inhibiting the internalization process of exogenous DNA.  The fact which refers to the existence of one or more factors in seminal plasma that able to block sperm permeability must be taken into account. This means, extensive washing steps of ejaculate to remove seminal plasma is necessary and should be made before incubating sperm with exogenous DNA. Lauria and Gandolfi reviewed that seminal fluid inhibitors have two ways of inhibition to exogenous DNA, either directly or indirectly (Lauria and Gandolfi, 1993). These seminal plasma inhibitory factors may prevent transfection of intact sperm by foreign DNA (Camaioni et al., 1992).  Gandolfi showed that there is a consensus on the experiments made on seminal fluid of the ejaculated spermatozoa of mammals in the impermeability of sperm cell to the aggression of foreign DNA as long as seminal plasma is not removed (Gandolfi, 2000). Thus, seminal fluid prevents any foreign DNA from binding with its receptor on the sperm cell

Risk communication with Arab patients with cancer: a qualitative study of nurses and pharmacists

Objectives To explore pharmacist and nurse views and experiences in educating patients regarding their treatment safety and tolerability as well as the roles of other professions in this regard. Design In this qualitative study, six focus group discussions were conducted. Setting The National Center for Cancer Care and Research in Qatar. Participants Eleven pharmacists and 22 nurses providing direct patient care. Results Concepts related to three key themes were drawn from the seeding questions and included factors for determining the level of risk they communicated: the specific treatment regimen in question; the patient; and their assessment of the patient. Patient-related considerations arose from additional subthemes; both nurses and pharmacists described aspects related to the perceived psychological health status of the patient, as well as anticipated comprehension, as ascertained by demonstrated education and language abilities. In all discussions, it was noted that physician and family non-disclosure of cancer diagnosis to the patient profoundly influenced the nature of information they provided. While a high level of cohesion in safety communication prioritisation among these two health disciplines was found, a number of pharmacists asserted a more formal role compared to informal and repeated teaching by nurses. Conclusions Nurses and pharmacists in this Middle East healthcare environment were not reluctant to discuss treatment side effects with patients and draw on similar professional judgements in prioritising treatment risk information. We found that they did not always recognise each other's informal educational encounters and that there are opportunities to explore increased collaboration in this regard to enhance the patient care experience.Undergraduate Research Experience Program award (UREP 14-001-3-001) from the Qatar National Research Fund (a member of Qatar Foundation)
