It is usually based on the principle of partition of solute between two phases. It usually consists of a mobile phase and a stationary phase. The advancement of the mobile process in the planar stationary stage is evoked by different external or internal forces. Capillarity and gravity are the intrinsic force whereas external forces are electric field, pump, and centrifugal forces. Thin layer chromatography and high-pressure thin layer chromatography are based on the adsorption theory. Forced flow thin layer chromatography is also based on the adsorption principle. FFTLC is an authoritative method of separation that uses a solvent pump to extract the sample mixture into a pressurized ultra-micro cavity containing an adsorbent analytical or preparative planer bed. FFTLC needs no or slight sample preparation as in TLC. One relation between FFTLC and high-pressure liquid chromatography is that as in HPLC, the maximum layer length is used for analytical and preparatory separation. FFTLC is a process in which continuous production and continual evaporation of the mobile phase from the end of the chromatography plate produces forced-flow. Here, we focus on FFTLC, an advanced and more sophisticated chromatographic technique.

In the present study, our approach is to develop the preparation and characterization by physicochemical methods of an adsorbent material, from mixed red and hard wood sawdust. The preparation of the adsorbent material includes the sieving of the sawdust, the extraction of the extractables, a pretreatment with sulphuric acid H2SO4 (at 20% to 50% and at 80%) as an activating agent. The chemical modification, which serves to improve the adsorption capacity of the material, is verified by means of analysis: Fourier Transfer Infrared (FTIR) and X-Ray Diffraction (XRD) (crystallinity index). The chemical modification of the lignocellulosic material induced a significant elimination of hemicelluloses, which resulted in the appearance of a new microstructure, especially in the case of acid pre-hydrolysis at 50% and 80%, in favor of increasing its potential adsorption capacity proven by testing it on the adsorption of acetic acid.

Analgesic drugs act in various ways on the peripheral and central nervous systems. They are distinct from anesthetics, which reversibly eliminate sensation, and include Ibuprofen, the non-steroidal anti-inflammatory drugs [NSAIDs] such as the salicylates, and opioid drugs such as morphine and opium. In choosing analgesics, the severity and response to other medication determines the choice of agent; the World Health Organization [WHO] pain ladder specifies mild analgesics as its first step. Analgesia/Pain is ill-defined unpleasant sensation evoked by stimulus [external / internal] – the most important symptom giving warning signal and primarily protective in nature. Analgesia due to blockade of pain nerve sensitizing mechanism induced by bradykinin, TNFα, ILs. An analgesic is a drug that selectively relieves pain by acting in the CNS or on peripheral pain mechanisms, without significantly altering consciousness. Pain is a warning signal, primarily protective in nature, but causes discomfort and suffering; may even be unbearable and incapacitating. Excessive pain may produce other effects- sinking sensation, apprehension, sweating, nausea, palpitation, rise or fall in BP, tachypnoea. Analgesics relieve pain as symptoms, without affecting it’s causes. Snehal A, Rokade , Rupali. V.

The authenticity of honey in regard to its botanical or geographic origin and adulteration has drawn more attention in recent years. Honey is a natural, ready-to-eat product that has a high level of nutrition and offers a number of health advantages. In order to counteract frequent honey frauds including mislabeling honey's origin and adulteration with sugar or syrups, companies and consumers must prioritize the authentication of honey. Different analytical techniques are employed to identify genuine honey. The traditional analytical procedures are still employed in conjunction with cutting-edge approaches as part of preliminary screening, processing, and product standards with a wide variety of tools and methodologies. The majority of analytical techniques offer pollen distribution information, physicochemical data, and profiles of phenolic, flavonoid, carbohydrate, amino acid, fragrance, and individual marker components. In this study, the sugar profile, physicochemical characteristics, and honey quality of ten samples of Algerian honey from various areas were examined. High-performance liquid chromatography was used to identify the sugars (fructose, glucose, sucrose, maltose, and lactose) as well as the physicochemical characteristics (moisture, water activity, pH, acidity, conductivity, and color) using the Harmonized Method of the International Honey Commission. The quality of honey throughout storage and processing was not appropriately described by the moisture content alone.

The objective of this study is to evaluate the in vitro litholytic and inhibitory effects of the leaf aqueous extract of Fraxinus excelsior L plant on the crystallization of struvite. The plant is commonly used in traditional Algerian medicine.A characterization method of Fraxinus excelsior L plant was first performed to determine the total phenolic and flavonoid compounds of Fraxinus excelsior L leaf aqueous extract. Struvite crystals prepared with two different processes had subsequently undergone an inhibition assay by supplementing Aqueous Extract with varying concentrations. In the first process, struvite was biologically crystallized in a synthetic urine in the presence of Proteus mirabilis during 24 hours of incubation period. This was followed by the addition of Aqueous Extract, the effect of which was evaluated after 1-hour. In the second process, struvite crystals were chemically synthesized for 30 minutes in the presence of aqueous extract. These two processes allow to assess, respectively, the litholytic effect of aqueous extract on the previously formed struvite crystals and the inhibitory effect of the crystallization of struvite. These various tests of crystallization and inhibition of struvite crystals were conducted by Polarized Light Microscopy (PLM) and Fourier Transform Infrared (FTIR) Spectroscopy. The results reveal that this Aqueous Extract contains an estimated total phenolic content of 60.92 ± 0.94 mg gallic acid equivalent (GAE)/g of extract and a total flavonoid content of 19.32 ± 0.75 mg quercetin equivalent (QE)/g of extract. The in vitro struvite crystals dissolution testing revealed a significant litholytic effect. Also, the struvite crystallization inhibition testing showed that it exerted a significant inhibitory effect observed with polarized light.The effect of this extract is evident against struvite crystals with a conclusive litholytic and inhibitory potential. The present results open up significant preventive management prospects for this type of lithiasis.

Most of the synthesized compounds that have the character of liquid crystals in their constitution include aromatic molecules. In addition, there is little work that replaces this type of molecules with heterogeneous molecules that have a liquid crystalline character. This study constitutes an approach for the synthesis of a new molecule azoesters involves a 1,3,4-oxadiazole unit instead of aromatic rings, and which exhibits liquid crystalline characters. A liquid crystal has been prepared and characterized. The thermodynamic characteristics of the n-alkanes for the filled column were studied by reverse gas chromatography. The intermediate products, as well as the mesogens obtained, were characterized by various experimental analysis techniques such as infrared spectrometry (IR) and nuclear magnetic resonance (NMR). The thermal properties of synthesized liquid crystal require the use of DSC technique. Thermodynamic parameters such as enthalpies, partial solution molar entropy and infinite dilution, were determined for the liquid crystal-solvent system. The thermodynamic quantities show that these values depend on the number of carbon atoms of the CL phase terminal substituent. The transition temperatures obtained by gas chromatography are in good agreement with those found by DSC. Bouchareb Hadj, Benalia Mokhtar, Djedid Mebrouk, Tafer Asma, Mounir Habati, Al-Dujaili A.

A computer program based on one dimensional implicit finite difference method and energy balance approach has been developed to investigate the behavior of the studied system under the real climate conditions of a typical summer day in Adrar city, Algeria. The simulation findings reveal that solar parabolic trough collector with small area of 6m² and storage tank of 0.3m3 can ensure higher storage tank temperature able to drive an absorption cooling machine. Solar system with hybrid nanofluid shows superior performance compared to single nanofluid and pure water. Furthermore, the effect of nanoparticle's volume fraction is evaluated. The heat storage tank temperature can attain starting operating chiller temperature more rapidly with small volume fraction equal to 0.2% in the case of Cu-Al2O3/Water hybrid nanofluid.
