A Survey of SQL Injection Attack Detection and Prevention

Structured Query Language Injection Attack (SQLIA) is the most exposed to attack on the Internet. From this attack, the attacker can take control of the database therefore be able to interpolate the data from the database server for the website. Hence, the big challenge became to secure such website against attack via the Internet. We have presented different types of attack methods and prevention techniques of SQLIA which were used to aid the design and implementation of our model. In the paper, work is separated into two parts. The first aims to put SQLIA into perspective by outlining some of the materials and researches that have already been completed. The section suggesting methods of mitigating SQLIA aims to clarify some misconceptions about SQLIA prevention and provides some useful tips to software developers and database administrators. The second details the creation of a filtering proxy server used to prevent a SQL injection attack and analyses the performance impact of the filtering process on web application.

Milestones of the Modeling of Human Physiology

An overview of about 70-year research efforts in area of mathematical modeling of human physiology is provided.The overview has two goals:(1)to recognize the main advantages and causes of disadvantages or disappointments;(2)to distinguish the most promising approach for creating future models.Until recently,efforts in the modeling of quantitative physiology were concentrated on the solving of three main types of tasks:(1)how to establish the input-output dynamic characteristics of a given isolated organ or isolated anatomical-functional system(AFS);(2)how to create a computer-based simulator of physiological complex systems(PCM)containing many organs and AFSs;and(3)how to create multi-scale models capable of simulating and explaining causalities in organs,AFSs,PCMs,and in the entire organism in terms that will allow using such models for simulating pathological scenarios(the“Physiome”project)too.The critical analysis of the modeling experience and recent physiological concepts convinced us that the platform provided by the paradigm of physiological super-systems(PPS)looks like the most promising platform for further modeling.PPS causally combines activities of specific intracellular mechanisms(self-tunable but of limited capacities)with their extracellular enhancers.The enhancement appears due to the increase of nutrients incomes toward cells affected because of low energy and inadequate chemical composition of cytoplasm.Every enhancer has its activator chemicals released by the affected cells.In fact,PPS,indicating causal relationships between cellscale and upper-scales(in organs,AFSs,PCMs)physiological activities,is the single platform for future models.They must definitely describe when and how the bottom-to-up information flows do appear and how is the organism-scale adaptation activated against destructive trends in cells.

Several Theoretical and Applied Problems of Human Extreme Physi­ology:Mathematical Modeling

Human cardiovascular system(CVS)and hemodynamics are critically sensitive to essential alterations of mechanical inertial forces in directions of head-legs(+Gz)or legs-head(-Gz).Typically,such alterations appear during pilotage maneuvers of modern high maneuverable airspace vehicles(HMAV).The vulnerability of pilots or passengers of HMAV to these altering forces depends on their three main characteristics:amplitude,dynamics,and duration.Special protections,proposed to minimize this vulnerability,should be improved in parallel with the increasing of these hazardous characteristics of HMAVs.Empiric testing of novel protection methods and tools is both expensive and hazardous.Therefore computer simulations are encouraged.Autonomic software(AS)for simulating and theoretical investigating of the main dynamic responses of human CVS to altering Gz is developed.AS is based on a system of quantitative mathematical models(QMM)consisting of about 1300 differential and algebraic equations.QMM describes the dynamics of both CVS(the cardiac pump function,baroreceptor control of parameters of cardiovascular net presented by means of lumped parameter vascular compartments)and non-biological variables(inertial forces,and used protections).The main function of AS is to provide physiologist-researcher by visualizations of calculated additional data concerning characteristics of both external and internal environments under high sustained accelerations and short-time microgravity.Additionally,AS can be useful as an educational tool able to show both researchers and young pilots the main hemodynamic effects caused by accelerations and acute weightlessness with and without use of different protection tools and technics.In this case,AS does help users to optimize training process aimed to ensure optimal-like human tolerance to the altered physical environment.Main physiological events appearing under different scenarios of accelerations and microgravity have been tested.

Endoscopic ultrasound with biopsy of omental mass for cholangiocarcinoma diagnosis in cirrhosis

In this report,a patient had a previous diagnosis of cholangiocarcinoma with an extended cholecystectomy. Three years later,he was evaluated for recurrent ascites. The patient had several large volume paracentesis, without evidence of malignant cells.Subsequently, endoscopic ultrasound(EUS)with fine needle aspiration (FNA)of both lymph and omental nodules was utilized.While the lymph nodes were negative for malignancy, the omental nodule was interrogated with multiple antibodies and was found to be positive for neoplasia. EUS with FNA can safely be used in patients with cirrhosis to spare the patient invasive evaluation such as exploratory laparotomy(ex-lap)for diagnosis and staging of cholangiocarcinoma.

Serum Vitamin D Levels and Severity of Liver Dysfunction in Cirrhotic Patients

Background and objective: Cirrhosis affects hundreds of millions of patients all around the world. Vitamin D deficiency is frequently observed in chronic hepatic disease. Vitamin D level may be an important survival marker in advanced liver cirrhosis. Material and Methods: The study is a sectional one of the descriptive-analytical type, where 90 of the patients with hepatic cirrhoses were selected with census sampling method. In all the cirrhotic patients, for diagnosis in clinical findings, the serological marker, autoantibodies were stable;biochemical endoscopy and imaging were the histological evidence and examinations and were then analyzed by SPSS version 22 software. Results: Based on the study, from the aspect of Child-Pugh classification, the highest vitamin D levels had the highest value in Child-Pugh class A with a frequency of 13 (43%) in the form of insufficiency, and had the highest value in Child-Pugh class B and C in the form of slight deficiency. Conclusion: It was specified based on the results obtained from the research that different vitamin D levels and liver failure severity have a significant relationship with each other (p < 0.05) in patients suffering from hepatic cirrhosis, such that the serum vitamin D level decreases as liver failure severity increases.

The Analysis of Scientific and Commercial Softwares Accuracy in GPS Observation Processing

The engineers use various softwares for observation processing and GPS networks, generally everyone who uses a device, he uses softwares with the same brand for the processing of it GPS processing networks by defined default parameters and models. The most outstanding issue is that, it should be understood, the application of which kinds of softwares will help us to gain the desirable accuracy and whether the accuracy of coordinate estimation is acceptable in all commercial softwares or not. In this article, we compared a series of softwares which engineers use for their data processing with powerful scientific software that meanwhile it is too hard and time consuming to learn it. We have considered accuracy and validity of scientific software, which gives acceptable results, as a baseline to see how much errors and difference is between this software and the commercial softwares, so we selected Bernese as a scientific software and LGO, Ashtech Solutions, CGO softwares as commercial softwares and we analyzed them and compared the applied models of the softwares with each other. To do so, we choose a GPS network from Tehran city and discussed it, in order to evaluate the measured accuracy for baselines and also coordinate system that after data processing, it was understood that if the polygon of a network is small, commercial softwares can be utilized with very high acceptable accuracies and even by Ephemerides Precise data, their accuracy will increase more, but if our network is more extended and bigger, there is no other choice except using scientific softwares to calculate coordinate that performs a processing by many parameters.

Change in pulse rate with Enviro Chip and dummy chip fixed on radiation emitting devices like mobile phones/computers/laptops of users—A double blind crossover study

Use of Electronic gadgets such as mobile phones, computers/laptops constitutes an integral part of human day-to-day activity in offices and businesses. Therefore, their use cannot be stopped. These electronic gadgets emit electromagnetic radiations, which are believed to be hazardous to human health. World Health Organization/International Agency for Research on Cancer has classified radiofrequency electromagnetic fields as possibly carcinogenic to humans (Group B). The Enviro Chip developed by Synergy Environics, India, is a radiation harmonizing chip which when fixed on electronic gadgets at specific locations claims to reduce stress level by reducing the pulse rate of users which may also result in improvement of other health parameters. In this study, we have tested the ability of the Enviro Chip to reduce pulse rate of people who may have developed high pulse rate due to prolonged use of electronic gadgets. This was the double blind crossover study conducted in 205 healthy volunteers having an average pulse rate of above 82 per Minute at Max Healthcare India. The primary objective of the study was to evaluate and compare the change in pulse rate over 14 measurements with the use of both the Enviro Chip and a Dummy chip from average pulse rate at baseline without the Placebo effect. The secondary objective was to evaluate the change in pulse rate gender-wise. Data analysis was done using Wilcoxon Sign Rank test. The study demonstrated statistical significant reduction in pulse rate over 14 measurements with the use of Enviro Chip in both male and female healthy volunteers

Nutraceutical Treatment of Patients with Polycystic Ovary Syndrome

Polycystic Ovary Syndrome (PCOS) is a common cause of infertility, requiring antioestrogen and, possibly, gonadotropin treatment for the induction of ovulation. However, patients suffering from this disease need long-term treatment since PCOS is associated with an increased risk of metabolic syndrome, hyperinsulinemia, oxidative stress, inflammation, cardiovascular disease, and cancer. Allopathic treatment includes the continuous use of oral contraceptives, preferentially with complementary anti-androgen activity, and metformin. However, these treatments only partially correct all aspects of the disease, while carrying potential adverse effects per se. Complementary and alternative medicine (CAM) offers opportunities for treatment through the use of nutraceuticals containing plant extracts, minerals, and vitamins with antioxidant, anti-inflammatory, and adaptogen capacity, as well as for correcting insulin resistance. Here we justify the formulation of the nutraceutical QALY® (Jona Pharma, Elversele, Belgium) that is composed of Ubiquinone Q10, the vitamins B9 and B12, the salts of zinc and selenium, the biomass of Haematococcus pluvialis, and the extracts of Mediterranean pine bark and of Rhodiola rosea. This can be complemented by phytotherapy with the extract of Momordica charantia plus alfa lipoic acid (Momordica plus®).

Laser back scatter: Limitation to higher repetition rate [kHz] Satellite Laser Ranging system

Satellite laser ranging(SLR)with higher repetition rate is the recent trend for its various advantages.Laser backscatter(coincidence between recently transmitted pulses and received pulses near the detector)is found to be a constraint for the repetition rates higher than 20 kHz,due to,overlapping with photons returning from a satellite with the present constellation of most of the SLR systems.Such an overlap occurs at every 75 km satellite distance change at 2 kHz repetition rate,and remains for about 7.5 km;for a 20 kHz system however,it will occur after every 7.5 km and remains for 7.5 km,resulting in constant backscatter overlap e leaving no chance to avoid it.The resulting noise is 5 times more than before causing a serious problem in detection and lowers the signal to noise ratio of the overall SLR system.However,decreasing energy per shot at higher repetition rates e assuming a constant power laser e the resulting backscatter may decrease fractionally.

Genuine Palestinian cabbage: Myth or fact. Comparison between Palestinian and Belgian coronary artery bypass grafting

Background: Outcomes post-CABG serves as an indicator of the quality and effectiveness of care given by health care providers. The primary aim of this study is to describe outcomes such as mortality, morbidity, length of hospitalization and hospital readmission post-CABG between Ramallah Ministry of Health Hospital and Ghent University hospital. Methods: A retrospective study is conducted on 200 matched patients who underwent isolated CABG in Ramallah hospital and Ghent University hospital between 2009 and 2011. Both groups were followed up in the post-operative period for minimum one year. Inferential statistics were performed to find the presence of relationship among variables. Kaplan-Meyer was performed to compare overall survival rates and freedom from adverse events. The logistic model was used to assess all factors that associated with readmission, mortality, morbidity and hospital stay. Findings: Both groups had comparable patient characteristics and operative data. Risk factors of diabetes (50%) and smoking (60%) were higher in Palestinian patients compared to (29%) and (31%) in Belgian patients. The mortality rate slightly, being higher among the Palestinian group, was 4% compared to 2% among the Belgium group. Occurrence of morbidity was less noted among Palestinian patients compared to Belgium patients (23%, 36%, P = 0.044 respectively). Palestinian patients had shorter hospital stay (IQR = 6 - 10,

Bilateral Massive Pulmonary Embolism on Disseminated Intravascular Coagulation (DIVC) after Severe Postpartum Haemorrhage

The authors report a case of bilateral pulmonary embolism (PE) with intermediate risk at the University Hospital center of Treichville (CHUT). This is a postpartum PE in a 37-year-old obese, multiparous woman with postpartum hemorrhage from uterine rupture after vaginal delivery initiated by injectable oxytocin. This postpartum haemorrhage was managed by massive transfusion and hysterectomy. The initiation of thromboprophylaxis was delayed in view of its coagulation record, the first 3 days. Later, the patient presented respiratory distress for which the completion of a pulmonary angioscanner made it possible to make the diagnosis of PE whose clinical evolution under heparinotherapy was favorable.

Individual with different Mizaj have different sensitivity to pain:a hypothesis

Pain is a state in which an individual experiences and reports severe discomfort or an uncomfortable sensation.It may be caused by many reasons such as thermal,chemical and mechanical stimuli.A physician can diagnose a disease to a very great extent on the different qualities of pain.Pain is a protective mechanism having signals in our nervous system.There are two types of pain,one is fast pain which is felt about 0.1 sec after stimuli and includes pricking pain,acute pain and electric pain,second is slow pain which is felt about 1 sec after the stimuli and includes burning pain,aching pain,throbbing pain,nauseous pain and chronic pain.Both type of pain has different conduction pathways.For pain the term Waja or Alam is used in Unani system of medicine,another ancient herbal medical system of India beside Ayurveda.Alam is a sensation against Tabiyat(Physis).Pain stops organs from their specific functions.According to Ibn Rushed in his book Kitabul Kulliyat,bad feeling of sensory system is called pain.Ibn Sina(Avecenna)has described two causes of pain as Sue-Mizaj Mukhtalif and Tafarruk-e-ittesal.Mizaj is base of Unani system of medicine which reflects body’s physiological condition by four kaifiyat which depends on humours.According to Unani philosophy safravi Mizaj individual will be hypersensitive and balghami and saudavi Mizaj individual will be hyposensitive to pain stimuli.
