SQL Injection is one of the vulnerabilities in OWASP's Top Ten List forWeb Based Application Exploitation. These type of attacks take place on Dynamic Web applications as they interact with databases for various operations. Current Content Management System like Drupal, Joomla or Wordpress have all information stored in their databases. A single intrusion into these type of websites can lead to overall control of websites by an attacker. Researchers are aware of basic SQL Injection attacks, but there are numerous SQL Injection attacks which are yet to be prevented and detected. Over here, we present the extensive review for the Advanced SQL Injection attack such as Fast Flux SQL Injection, Compounded SQL Injection and Deep Blind SQL Injection. We also analyze the detection and prevention using the classical methods as well as modern approaches. We will be discussing the Comparative Evaluation for prevention of SQL Injection.

The pharmacokinetics of a diclofenac sodium was investigated in swine. A single intravenous (i.v.) or intramuscular (i.m.) injection of 5% diclofenac sodium (concentration = 2.5 mg · kg-1) was administered to 8 healthy pigs according to a two-period crossover design. The pharmacokinetic parameters were calculated by non-compartmental analysis with DAS2.1.1 software. After a single i.v. administration, the main pharmacokinetic parameters of diclofenac sodium injection in swine were as follows: the elimination half-time (T1/2β) was 1.32±0.34 h; the area under the curve (AUC) was (55.50±5.50 μg · mL-1 h; the mean residence time (MRT) was 1.60±0.28 h; the apparent volume of distribution (Vd) was 0.50±0.05 L · kg-1; and the body clearance (CLB) was 0.26±0.04 L · (h · kg)-1. After the single i.m. administration, the pharmacokinetic parameters were as follows: peak time (Tmax) was 1.19±0.26 h; and peak concentration (Cmax) was 11.61±5.99 μg mL-1. The diclofenac sodium has the following pharmacokinetic characteristics in swine: rapid absorption and elimination; high peak concentration; and bioavailability.

The paper presents a static load test of a pile with the largest vertical load in Poland to-date up to the force of 23000 kN. The test was performed in the centre of Warsaw on the construction site of a future high-rise building to be the tallest building in European Union. The designed building height measured from the ground level is 310 meters including an 80-metre mast. The foundation of the building was designed as a Combined Piled Raft Foundation (CPRF) utilising the barrettes and diaphragm walls technology. The test was carried out on barrettes with lengths of approx. 28 and 34 m and was aimed to estimate the stiffness (load-settlement relation) of the designed 17.5 metre-long barrette situated below the foundation level. In addition to that a series of extensometric sensors was placed inside the barrette to determine the distribution of the axial force.

The application of enhanced oil recovery processes (EOR – Enhanced Oil Recovery) on oil fields increases recovery efficiency. This is especially important in depleted and mature fields. This should result in an increase in production by raising the recovery factor (the ratio of oil produced to total geological reserves). This review presents the growing trend of gas injection (particularly carbon dioxide). In Polish oil fields, conventional methods are currently used. This means that much can still be done in this area. The selection of the optimum method for a given field is a complex procedure consisting of many stages, from collecting data about the field, through more advanced data interpretation, to working out a detailed proposal for the most efficient method of extraction. The pre-selection stage involves excluding methods which, owing to their specific mechanisms, cannot be used for a particular field – e.g. thermal methods in light oil fields or nitrogen injection into shallow reservoirs. This paper analyzes the potential for the application of EOR methods in Poland using a binary technical screening method. Forty-nine, mature Polish oil fields were analyzed. Apart from the rock type, other parameters were also taken into account in the analysis as follows: oil density and viscosity, average porosity, permeability and thickness of the reservoir, and also depth of deposit. In regard to the criteria for the EOR methods applied, the subjects of analysis are oil fields with medium density and viscosity and low permeability (double porosity in carbonate rocks), which are at a relatively shallow or medium depth of deposit. The results of analysis show that gas injection methods, especially carbon dioxide or nitrogen, have the highest potential. Application of this method must be preceded by detailed research and field pilot tests. International experience cannot be applied directly to Poland because of different field characteristics as well as technological and economic conditions.

Arriving at a good combination of coding and modulation schemes that can achieve good error correction constitutes a challenge in digital communication systems. In this work, we explore the combination of permutation coding (PC) and pulse amplitude modulation (PAM) for mitigating channel errors in the presence of background noise and jitter. Since PAM is characterised with bi-polar constellations, Euclidean distance is a good choice for predicting the performance of such coded modulation setup. In order to address certain challenges facing PCs, we therefore introduce injections in the coding system, together with a modified form of PAM system. This modification entails constraining the PAM constellations to the size of the codeword’s symbol. The results obtained demonstrate the strength of the modified coded PAM system over the conventional PC coded PAM system.

Approximately 80% of water extracted from oil and gas deposits in Poland is disposed of by injection into the rock matrix. The aim of the model research was to predict both the hydrochemical reactions of water injected into wells for its disposal and the hydrogeochemical processes in the reservoir formation. The purpose of hydrogeochemical modeling of the hydrocarbon formation was also to determine the potential of formation waters, injection waters, and their mixtures to precipitate and form mineral sediments, and to determine the corrosion risk to the well. In order to evaluate saturation indices and corrosion ratios, the geochemical programs PHREEQC and DownHole SAT were used. The results of hydrogeochemical modeling indicate the possible occurrence of clogging in the well and the near-well zone caused mainly by the precipitation of iron compounds (iron hydroxide Fe(OH)3 and siderite FeCO3) from the formation water due to the presence of high pressures and temperatures (HPHT). There is also a high certainty of the precipitation of carbonate sediments (calcite CaCO3, strontianite SrCO3, magnesite MgCO3, siderite FeCO3) from the injection water within the whole range of tested pressures and temperatures. The model simulations show that temperature increase has a much greater impact on the potential for precipitation of mineral phases than pressure increase.
