Moral Views of Thiruvarutpa From Vallalar’s Point of View
Ramalinga Adigalar is credited with giving clarity and simplicity to Tamil poetry, which has been rich for more than 20 centuries and brought about a positive turn in the last century. It guides mankind to be completely liberated from suffering without getting buried in religion and philosophy. Vallalar's divine policy was in a manner that alleviated the sufferings of the poor and needy. It was aimed at freeing people from superstition. His religious policy was neither blind nor crude. His doctrine of God arising out of the practice of Saivam led him to the path of pure righteousness and guided him. The purpose of this article is to examine from Vallalar's point of view how Thiruvarutpa directs mankind to live with dignity without enmity and to rise to become great men
A Clinical study of Microvascular Complications in Newly Diagnosed Diabetes Mellitus
BACKGROUND AND OBJECTIVES:
Type 2 diabetes mellitus may be present for up to a decade before diagnosis of the disease. Microvascular complications do not occur at the onset of the disease. However the main reason for the presentation of microvascular complications at the time of diagnosis itself is a long asymptomatic period and delay in diagnosis. Aim of this study is the clinical detection of the various microvascular complications in newly detected Type 2 diabetes.
METHODS:
A total number of 100 newly detected type 2 diabetic patients aged between 30 and 75 yrs seen as out patients in the Department of Diabetology in Coimbatore Medical College Hospital over a period of 1 year formed the study population. Thorough clinical examination and relevant investigations were carried out in all the patients. Fundus
examination for retinopathy was carried out initially by Direct Ophthalmoscope. This was followed by Fundus Fluorescein Angiography (FFA) in patients with normal findings in direct ophthalmoscope. Assessment of nephropathy was done by measuring concentration of albumin in urine (early morning sample). Detection of neuropathy was done by Foot sensitivity testing by monofilament, Deep tendon reflex testing by percussion hammer, and Vibration perception testing by 128HZ tuning fork.
RESULTS:
Out of the total 100 newly detected diabetes 51% were males and 49% were females. Mean age of the patients was 53.39±9.554. BMI studied in the patients showed
that 53% were overweight and 13 % were obese. Family history was positive in 31% of the study population. Mean FBS was 198.29±35.888; Mean PPBS was 279.45±59.072. Among the study population 32% were smokers and 35% were alcoholics. The mean Total Cholesterol, TGL, LDL and HDL were 221.23±27.445, 139.71±33.92067, 122.45±17.218 and46.97±3.737 respectively. About 24% of the patients presented with symptoms suggestive of neuropathy. But after detailed examination 13% of them were found to have clinical neuropathy. 24% of patients presented with Diabetic Nephropathy.
The incidence of Diabetic Retinopathy was 20%, out of which all of them had NPDR.
CONCLUSION:
This study showed that 39% of the patients presented with microvascular complications at the time of diagnosis itself. This should alert physicians for early screening of diabetes and early detection of microvascular complications for early
intervention to prevent further complications
Application of 3R Principles in Construction Project-A Review
Now a days recycling of waste in and around the world becomes a challenge today. Primarily, due to materials markets particularly secondary materials are yet to be integrated. The 3R principles like Reducing, Reusing and recycling of waste have been engaged over the years, and in this regard. The different techniques have been explored. However, the applications are limited to economic and environmental aspects. This paper discusses the expenses and settlement in use derivative resources and focal point on investigating use again and recycles for main wealth of building resources which may include concrete, metal, wood, cardboard/paper and plasterboard etc. Data pertaining to the resources are obtained from demolition specialists and contractors. From the literatures it clearly shows, that the construction material recovery process with fully incorporated 3R's principle contributes to saving energy and natural resources
Stoichiometry control of sputtered CuCl thin films: Influence on ultraviolet emission properties
We demonstrate that the chemical composition of the sputtered CuCl thin films could be finely controlled by adjusting the bias to the substrate. The films deposited without any intentional bias were Cl rich (CuCl1+x), a bias of −22 V yielded stoichiometric CuCl, and a further increase in the negative bias resulted in Cl deficient films (CuCl1−x). The crystalline and optical properties were found to be associated with the chemical composition. Cl rich films showed a deep level green emission at around 515 nm in addition to ultraviolet (UV) excitonic emission. The stoichiometric films have higher optical quality, exhibiting a sharp UV emission at around 385 nm at room temperature, compared to nonstoichiometric samples. Visible luminescence related to deep level defects was not observed in the stoichiometric films. Changes in energy of the flux from the target and the subsequent ion bombardment on the substrate surface are correlated with the variations in chemical composition and their impact on the film microstructure and UV emission
6-[(2E)-3,7-Dimethylocta-2,6-dien-1-yl]-5,7-dihydroxy-8-(2-methylbutanoyl)-4-phenyl-2H-chromen-2-one–6-[(2E)-3,7-dimethylocta-2,6-dien-1-yl]-5,7-dihydroxy-8-(3-methylbutanoyl)-4-phenyl-2H-chromen-2-one (1/1) from Mesua elegans 1
The title co-crystal, C30H34O5·C30H34O5, comprises a 1:1 mixture of two mostly superimposed molecules with the same chemical formula that differ in the nature of the substituent (2-methylbutanoyl or 3-methylbutanoyl) bound at the exocyclic ketone. The lactone ring is close to planar (r.m.s. deviation = 0.058 Å) and the phenyl ring is twisted out of this plane [dihedral angle = 60.08 (9)°]. The geranyl substituent is almost normal to benzene ring to which it is connected [C—C—Car—Car (ar = aromatic) torsion angle = −87.8 (2)°]. Intramolecular O—H⋯O and O—H⋯π interactions are formed. In the crystal, supramolecular chains are formed along the a axis owing to C—H⋯O contacts, with the lactone carbonyl atom accepting two such bonds

Locallyknown as Keerichala, regular landings of A. sirmwas observed in all the major landing centres alongthe Thiruvananthapuram coast like Mampally,Anjengo, Perumathura, Thazhampally, Marianad,Valiyathura, Poonthura etc
Batch kinetic studies of adsorption of Cu(II) ions from aqueous solutions onto alginate nanoparticles/PEG binary blend
Among the most prevalent natural biopolymers is alginate. The current effort focuses on creating the binary blend of Alg-Nps/PEG. PEG is a great option because of its many distinctive qualities. Blends of polymers mix the characteristics of the separate polymers. FTIR results show intermolecular hydrogen bonding between Alg-Nps/PEG binary blend. Morphological and cross-sectional studies were analyzed using SEM. Various parameters impacting the Cu(II) ion adsorption, including pH, contact time, and adsorbent concentrations, have been examined in a batch adsorption method utilizing an Alg-Nps/PEG binary blend. Pseudo-first order, pseudo-second order, and intra particle Weber-Morris diffusion parameters have been determined. The experimental data fit the pseudo-second order kinetics model quite well when compared to the pseudo first order and intra-particular diffusion models

Adsorption of chromium from aqueous solution using Chitosan-g-Graphene /Hydroxyapatite composite
The preparation and characterisation of a polymeric composite incorporating graphene, hydroxyapatite, and chitosan as an adsorbent to remove chromium (VI) from wastewater. The FTIR and XRD studies supported the composite's production. Analysis of surface morphology and heat stability involved TGA and SEM studies. A batch adsorption was run to determine the efficacy of the adsorbent by varying contact time, adsorbent dose, and pH. The kinetics of the adsorption process were examined using pseudo-first and second order kinetic models after the equilibrium data had been fitted with the Langmuir and Freundlich isotherms. The findings showed that pseudo second order kinetics was utilised for the adsorption of Cr(VI) onto chitosan-grafted graphene/hydroxyapatite (CS-g-Gr/HA) composite
