Failure Analysis of Thermo-Mechanically Treated (TMT) Bar During Bending Operation: A Metallurgical Investigation by Souvik Das in Trends in Civil Engineering and its Architecture in Lupine Publishers

TMT bars means Thermo Mechanically Treated Bars made from medium carbon steel (Carbon 0.25 Max Wt. %) and are used in construction industry. Because of its corrosion and rust resistance features it is widely used in construction of buildings in humid areas as well as long lasting, high strength, quality construction. Quality aspects of these rebar’s are of significance as any inherent abnormality in the material could lead to unwanted productivity losses or quality claims. In this present study, rebar samples failed during bending operation were collected from construction end for understanding their quality aspect and potential causes of failure while bending. Visual observations of rebar sample (U-bend) longitudinal surface defects were observed in both the tension and compression zone. On appearance, metal folded over the rebar surfaces at an angle. Detailed microstructural investigation revealed that scale entrapment in defects. The above observations indicated that the defect was of lap type and which was generated during hot rolling process.

TMT ( Thermo-mechanical treated) rebar is the time proven match for reinforcing concrete structures on accounts of similarity in thermal expansion, ability to bond well with concrete and, above all, the ability to shoulder most of the tensile stress acting on the structure [1]. TMT bars means Thermo Mechanically Treated Bars made from medium carbon steel (Carbon 0.25 Max Wt. %) and are used in construction industry. Because of its corrosion and rust resistance features it is widely used in construction of buildings in humid areas as well as long lasting, high strength, quality construction [1]. Rebars are “hot rolled” from steel billets and subjected to on-line thermo-mechanical treatment in three successive stages.

Recently much emphasis is being laid on the development of micro particulate DDS in preference to single unit systems because of their potential benefits such as increased bioavailability, reduced risk of systemic toxicity, reduced risk of local irritation and predictable gastric emptying. The objective of the present study is to prepare and evaluate micro particulate drug delivery systems of Gliclazide using starch acetate, a new modified starch for oral controlled release. The starch acetate (DS 2.75) was freely soluble in chloroform and insoluble in several aqueous fluids and organic solvents. Chloroform could be used as solvent for starch acetate in the preparation of micro particles, microcapsules and in film coating Spherical starch acetate- Gliclazide micro particles could be prepared by the emulsification-solvent evaporation method. The method is industrially feasible as it involves emulsification and removal of the solvent, which can be controlled precisely. The emulsification solvent evaporation method was reproducible with regard to size and size distribution of the micro particles. About 65-70% of micro particles in each batch were in the size range 35/50 mesh (398.5μm) Encapsulation efficiency was in the range 96.0-99.3 % in the preparation of micro particles. Gliclazide release from the starch acetate micro particles was slow and spread over longer periods of time. The drug release depended on the proportion of core: coat in the micro particles. A good linear relationship (R2=0.826) between percent coat and release rate (ko) was observed.

Immunoglobulin G4-related disease (IgG4-RD) is an increasingly recognized immune-mediated condition comprised of a collection of disorders that share particular pathologic, serologic, and clinical features [1,2]. These disorders were previously thought to be unrelated [3-5]. The commonly shared features include tumor-like swelling of involved organs, a lymphoplasmacytic infiltrate enriched in IgG4-positive plasma cells, and a variable degree of fibrosis that has a characteristic “storiform” pattern. In addition, elevated serum concentrations of IgG4 are found in 60 to 70 percent of patients with IgG4-RD. IgG4-related sclerosing cholangitis (IgG4-SC) is a characteristic type of sclerosing cholangitis, with an unknown pathogenic mechanism. Patients with IgG4-SC display increased serum IgG4 levels [6] and dense infiltration of IgG4-positive plasma cells with extensive fibrosis in the bile duct wall [7]. Circular and symmetrical thickening of the bile duct wall is observed in the areas without stenosis that appear normal on cholangiography, as well as in the stenotic areas [8]. IgG4-SC has been recently recognized as an IgG4- related disease. IgG4-SC is frequently associated with autoimmune pancreatitis (AIP). IgG4-related dacryoadenitis/sialadenitis and IgG4-related retroperitoneal fibrosis are also occasionally observed in IgG4-SC [9-12]. However, some IgG4-SC cases do not involve other organs. IgG4-SC is most common in elderly men. Obstructive jaundice is frequently observed in IgG4-SC.A number of diseases, such as, Cystic fibrosis, Chronic obstructive Choledocholithiasis, Biliary strictures (secondary to surgical trauma, chronic pancreatitis), Anastomotic strictures in liver graft, Neoplasms (benign, malignant, metastatic), Infections, hypertonic saline instillation in the bile ducts, Post-traumatic sclerosing cholangitis, Systemic vasculitis, Amyloidosis, Radiation injury, Sarcoidosis, Systemic mastocytosis, Hypereosinophilic syndrome, Hodgkin’s disease, may easily be confused with IgG4- related sclerosing cholangitis, or coexist in a patient [13]. In this case, report 57 years male patient presented with jaundice, fatigue, weight loss, oral moniliasis and right sided neck swelling. He was misdiagnosed as Cholangiocarcinoma.

To Evaluate Different Soft Tissue Liners, as Functional Impression Materials, by Determining its Effect on Surface Roughness of Dental Stone Over a Time Period: An In-Vitro Study - Lupine Publishers

To Evaluate Different Soft Tissue Liners, as Functional Impression Materials, by Determining its Effect on Surface Roughness of Dental Stone Over a Time Period: An In-Vitro Study by Swapnil B Shankargouda in MADOHC- Lupine Publishers
To evaluate, compare and contrast the changes in surface roughness of dental stone casts, recovered from commercially available chair-side soft liners, used as functional impression materials. Ten disk-shaped denture soft liner samples [18 mm wide × 2 mm thick] were fabricated and dental stone poured over it after zero hours [control], one day, seven days, fourteen days and twenty one days, with a total sample size of 100 obtained from GC SOFT LINER [50 samples] and MOLLOSIL [50 samples] respectively.The dental stone samples were then evaluated for mean surface roughness values [Ra] using a profilometer.Student’s paired t test [p<0.05] and Co-efficient of variance [C.V] test was used for statistical analysis. The mean surface roughness values of MOLLOSIL samples increased gradually and consistently over the period of zero hours to twenty-one days in comparison to the GC SOFT LINER samples.Within the limitations of this study, silicone-based soft tissue liner showed better results than the acrylic-based soft liner in terms of surface roughness, over the period of zero hours to twenty-one days.

Combined Digital and Traditional Bite Registration - Lupine Publishers

Combined Digital and Traditional Bite Registration by Sadek Bakdach in MADOHC - Lupine Publishers

A high percentage of dental restorative procedures failure is attributed to the failure of maintaining the patient's occlusal patterns, and this fact becomes more and more valid as the restoration is more and more extensive. Our need to evaluate the distribution and the quality of occlusal forces is of a growing importance along with our growing knowledge of the masticatory system's sensational perception in the Central Nervous System, keeping in mind that the CNS potential adaptation is of a limited capacity and this is related to some individual factors of the patient (age is a major factor).

Chemoautotrophic and lithotrophic microorganisms are known to participate in the deposit formation and the rock weathering, but the results of such chemoautotroph-mediated biogeochemical activity and mass transfer strongly differ depending on the ionic composition of the medium, the salt conductivity effects and the Pourbaix diagrams of their medium, as well as on some other physico-chemical parameters which are often not considered as the active external factors for the sake of simplicity. The early biogeochemical considerations underlying the models and kinetic approaches to the analysis of such processes are mostly phenomenological and empirical and do not disclose the essence of the processes occurring at the boundary between the medium processed by the microorganisms and their active surface. Meanwhile, from the standpoint of biochemical physics, and especially biological kinetics, the mechanisms realizing at the interface or in its diffusion viscinity are decisive in such processes as the reagent input into the micro reactor-like biological compartments and aggregation upon biomineralization, which are usually biomembrane-mediated. Specificity of chemoautotrophic microorganisms to the chemically different media indicates the difference in their membrane properties within the natural mineral medium.

Post-operative pain management in cases undergoing total abdominal hysterectomy is considered a major challenge for both gynecologists and anesthesiologists aiming for enhancing patient satisfaction and level of health care service requiring multidisciplinary management and planning regarding the pathway of pain management of pain [1,2]. Despite the fact that epidural form of analgesia is an efficient mode of managing post-operative pain in abdominal surgeries however less invasive forms are considered more practical and applicable for many health care systems [3,4].

Local analgesia infiltration is considered a simple and efficient mode of pain management that has reduced costs in comparison to epidural analgesia. Advancing the pain management protocols could enhance patient post-operative recovery and improve clinical outcomes [5,6]. A widely implemented synthetic opioid known as pethidine causes its analgesic action by Functioning as an agonist on opioid receptors, furthermore it has been revealed and displayed to exert a local anesthetic impact chiefly via Linked to its interfaces with sodium‑ion Channels that are voltage‑dependent. peripheral nerve conduction blockage action has been revealed and displayed widely in various in vivo and in vitro experimental animal research studies that makes its applicability in clinical practice in humans a promising protocol of management [7,8].

Application of Non-Destructive Testing and Signal Processing Characteristics to Identify Defects and Microstructural Changes in Advanced High Strength Steels by Isaac Garcia C in Trends in Civil Engineering and its Architecture in Lupine Publishers

Nondestructive testing (NDT) and signal processing were used to detect, locate and define surface and internal defects in unidirectionally solidified laboratory ingots. These defects included cracks, voids, coarse non-metallic inclusions and heavy chemical and microstructural segregation. Many NDT techniques have been developed and used to assess the presence of these defects. The factors responsible for these defects are often related to mechanical, thermal, or transformation stresses during the solidification process of continuously cast steels. The high thermal stresses result from the difference expansion or contraction behavior caused by the frequency of the temperature fluctuation during solidification. In order to study the effect of these temperature fluctuations to the defects, a specially designed copper chill mold that simulates the solidification rate of continuously cast slabs was designed. In addition, a NDT-UT system was applied to localize and describe the presence of defects caused by thermal or transformation stresses. Furthermore, the signal processing analysis was used to characterize the changes in microstructure and hardness. The results of those studies are presented and discussed.

The Aging Process and Time by Patrice F Dassonville in PRJFGS in Lupine Publishers.


First of all, let's see why aging is a consequence rather than a cause., through three examples:
    a) The gradual staining of teeth does not result from aging; instead of that, it's a prodrome of aging.
    b) Wrinkles are not the result of aging; they appear when cells have exhausted their ability of scissiparity. We can say that wrinkles are one of causes of aging among others (inter alia)
    « Wrinkles (observed reality) « ⇒ aging (concept) »
    c) Osteoarthritis is not the result of aging; it results rather from antecedent factors. In fact, aging is a consequence of osteoarthritis:
    « Osteoarthritis (observed reality » ⇒ « aging (concept) »
    Wrinkles and osteoarthritis are syndromes of aging
    Medicine draws a distinction between chronological age, which is expressed with time units, and biological age, which depends on the physical health of an individual, and which is expressed in units of estimated time. For non living things, such as artifacts, we have introduced the expression "technical age".

Long time ago it was wrongly thought that tumor genes and cells are only existence in the exact tumor site. In spite of the fact of the hypothesis that circulating tumor cells (CTCs) are a fundamental prerequisite to metastasis ( first projected in the 1896 by Thomas Ashworth, an Australian pathologist, ) and the presence of cfDNA report in human plasma by Mandel and Metals in 1948, liquid biopsy were totally ignored till 1977. In 1977, researchers made the novel observation that cancer patients carried cell-free DNA in their peripheral blood which was Initial progress on further of liquid biopsy. Without a doubt, significant progress was not made until recent years with the advent of Next Generation Sequencing (NGS) technology, which significantly improved the sensitivity and specificity of ctDNA detection. Interestingly, research in this field of liquid biopsy has entered a “golden age” in which the huge potential of liquid biopsy main components including CTCs, cfDNA and exosomes make tumor diagnosis and treatment much clearer than before. Liquid biopsy tests are fast traction as a viable substitute to traditional diagnostic tests for cancer. It has the potential to facilitate detect cancer at earlier stages, present a less-expensive and less-invasive way to monitor patients throughout treatment, and can help doctors make better decisions about which drugs are the best fit for personal patients.
