A material other than water, aggregates, or cement that is used as an ingredient concrete or mortor to control setting and early hardening, workability, or to provide additional cementing properties. In this paper analysis of properties of concrete using hen’s feathers dipping in saltwater as admixture is studied and verified the strength of concrete to the normal Portland cement. As hens feather are most complex integumentary appendages formed in tie follicles in the epidermis, or outer skin layer that produce keratin proteins.

AbstractUnderwater optical wireless communications (UOWC) have recently received considerable attention for both research and commercial use because of their facility to provide a much higher data rate than the traditional acoustic method within comparatively small distances. Many potential application of UWOC systems have been proposed for environmental monitoring, exploration, disaster precaution, and military operations. In all the above mentioned research works, high absorption and scattering of optical transmission in the water limits the benefits of UOWC systems to only few meters. In order to overcome these technical challenges, several new system design approaches proposed. This work is done in salt water. Salt water cannot be used for drinking because it causes dehydration. This paper analysis the performance of the system using different water samples like salt water, turbid water, normal water, etc.

The tremendous increment of demand on concrete made admixture one of major component. As admixtures help in enhancement of concrete physical and chemical admixture. In this paper analysis of sea shells as chemical admixture is studied and verified the strength of concrete and temperature emitted due to chemical reaction to the normal Portland cement. As sea shells contain calcium carbonate, CaCo3 as major composition, as calcium is one major component that helps in densifying and hardening of bones in all living things. The flexural and compressive strength has gradually increased; the transmission temperature and reduction time of exothermal reaction has reduced. Hence seashell acts as great admixture.

Aggregate in concrete acts as structural filler, these place a crucial than simple statement implies it is the material that the cement paste coats and blind together. Now a day’s using river sand is prohibited by government, as these cause soil erosion. In this paper analysis of properties of concrete using manufacture sand as course aggregate is studied and verified the strength of concrete and temperature emitted due to chemical reaction to the normal Portland cement. Using manufacture sand as course aggregate the temperature emitted due to exothermal reaction of concrete has reduced. Although the compressive strength of the concrete has reduced compared to normal concrete where no admixtures were used to enhance the properties of concrete.

The aim of this study is to prepare and characterize an alginate-chitosan hydrogel for wound dressing application. The influence of alginate concentrations (1%, 2%, 3% and 4% (w/v)) was investigated. This polyelectrolyte hydrogel is observed to be transparent and flexible. The SEM morphological structure of hydrogel is composed of a dense outer skin layer and a porous cross-section layer. The FTIR and DSC measurements indicated the protonated amino group of chitosan has reacted with the carbonyl group of alginate. Some other properties for the wound dressing application are also reported in other paper. Taken together these results point out that alginate-chitosan polyelectrolyte hydrogel can be considered for wound dressing applications.

Recently admixtures had made a major importance in the concrete manufacturing. These admixtures materials ranged from blood in the history to the recent retarding agents. In this paper analysis of properties of concrete using safety matches powder as admixture is studied and verified the strength of concrete and temperature emitted due to chemical reaction to the normal Portland cement. Using safety matches powder the temperature emitted due to exothermal reaction of concrete has reduced. This gives better results hence we can use this safety matches powder as an admixture where the reacting temperature and the emitting temperature place a crucial role in construction and maintenance.

Chemical admixtures are the ingredients in concrete other than Portland cement, water and aggregate those are added to mix immediately before or during mixing. These admixtures are primarily used to reduce the cost of concrete construction, to modify the properties of hardened concrete, to ensure the quality of concrete during mixing, transportation, placing curing and to overcome certain emergences during concrete operations. In this paper analysis of properties of concrete using potassium power as admixture is studied and verified the strength of concrete and temperature emitted due to chemical reaction to normal Portland cement. Using potassium powder the temperature emitted due to exothermal reaction of concrete has reduced. Thus gives better results hence we can use this potassium powder as an admixture where the temperature and the emitting temperatures place a crucial role in construction and maintenance.

At the beginning of the third millennium, we still do not have a definition of ‘fascia' recognized as valid by every researcher. This article attempts to give a new definition of the fascial system, including the epidermis, by comparing the mechanical-metabolic characteristics of the connective tissue and the skin. In fact, according to the latest classification deriving from the Fascia Nomenclature Committee, the outer skin layer is not considered as part of the fascial continuum. This article highlights the reasons for taking the functional characteristics of the tissue into consideration, rather than its mere structure. A brief discussion will address the questions as to what is considered as fascial tissue and from which embryonic germ layer the epidermis is formed. The notion that all the layers intersect will be highlighted, demonstrating that quoting precise definitions of tissue stratification in the living organism probably does not correspond to what happens in vivo. What we propose as a definition is not to be regarded as a point of arrival but as another departure.

Abstract Reconstruction of nasal defect is difficult and challenging. A full-thickness defect of nose requires reconstruction of thin inner lining, middle skeletal (bony/cartilaginous) support, and outer skin layer cover. Large full-thickness defects of nose require complex multistage reconstruction to achieve good functional and aesthetic result. We present here a case of 12-year-old boy, a known case of xeroderma pigmentosa, who underwent wide local excision for squamous cell carcinoma of the nose, leaving a near total defect of the external nose. The reconstruction was done with a suprafascial, thin radial artery forearm free-flap for the external cover as well as the inner lining along with the septal cartilage graft for skeletal support in a single stage.

Concrete admixture is added to enhance the properties of concrete to make its function as required. In this paper analysis of properties of concrete using of glass powder as admixture to concrete is studied and verified the strength of concrete and temperature emitted due to chemical reaction to the normal Portland cement. Using of glass powder as admixture the temperature emitted due to exothermal reaction of concrete has reduced. As glass has property of absorbing high temperature. This gives better results hence we can use this glass powder as an admixture. Where the reacting temperature and the emitting temperature place a crucial role in construction, and as glass powder is rigid and non-crystalloid solid this increase bond strength in concrete to increase its strength.
