Breast cancer is one of the most important causes of death among women. Breast cancer can be treated effectively only if it is detected at the early stages. Thermography plays a vital role in early detection of breast cancer. The principal aim of early detection of breast cancer is to identify the disease at a more curable stage and thus improve the prognosis and other vital clinical outcomes. ...

Only a few studies have been reported regarding human ear recognition in long-wave infrared (LWIR) band. Thus, we have created ear database based on LWIR. We have called that the database is “LWIR MIDAS” consisting of 2430 records of 81 subjects. Thermal band provides seamless operation both night and day, robust against spoofing with understanding ear liveness and invariant to illumination con...

We have synthesized 2,3,7,8,12,13,17,18-octachloro-meso-tetraphenylporphyrinatooxidovanadium(iv) (VOTPPCl8) and characterized by various spectroscopic (UV-Vis, IR and EPR) techniques, MALDI-TOF mass spectrometry and elemental analysis. The DFT optimized structure of VOTPPCl8 in CH3CN exhibited a highly nonplanar saddle shape conformation of the porphyrin macrocycle. The cyclic voltammogram of V...

The secondary structure of xylanase II from Trichoderma reesei is lost in an apparent irreversible cooperative process as temperature is increased with a midpoint transition of 58.8 ± 0.1°C. The shift of the spectral centre of mass above 50°C is also apparently cooperative with midpoint transition of 56.3 ± 0.2°C, but the existence of two isofluorescent points in the fluorescence emission spect...

Most of the floating systems have an inherent drawback of high variability in the GI transit time, invariably affecting the bioavailability of drug. An attempt has been made to develop floating drug delivery system for improving the drug bioavailability by prolongation of gastric residence time of famotidine in stomach. The floating microballoons were prepared using polymer Eudragit L-100 by so...

Thermography makes a significant contribution to the evaluation of patients suspected of having breast cancer. The obviously abnormal thermogram carries with it a high risk of cancer. This report summarizes the results of patients with questionable or stage Th III thermograms. From approximately 58,000 patients, most of whom had breast complaints, examined between August 1965 and June 1977, the...

Natural fiber as reinforcement filler in polymer composites is an attractive approach due to being fully biodegradable and cheap. However, incompatibility between hydrophilic natural fiber and hydrophobic polymer matrix restricts the application. The current studies focus on the effects of incorporation of silane treated OPMF into polylactic acid (PLA)/polycaprolactone (PCL)/nanoclay/OPMF hybri...

Biometrics is a technology used for measuring and analyzing a person's unique characteristics. Making a secure biometric system is not as easy as it might appear. The word biometrics is very often used as a synonym for the perfect security. Human Biometrics is now moving towards thermal imaging. Thermal imaging is simply the technique of using the heat given off by an object to produce an image...

The discovery of infrared radiation by William Herschel in 1800 led to John Herschel’s study of solar radiation that he imaged by evaporography. This he termed a thermogram. The measurement of temperature in medicine advanced with Dr Carl Wunderlich, who showed the significance of the use of temperature measurements for diagnosis of fever and for monitoring the course of temperature in relation...

Differential Scanning Calorimetry (DSC) of intact Escherichia coli (E. coli) was used to identify non-lipidic targets of the antimicrobial peptide (AMP) MSI-78. The DSC thermograms revealed that, in addition to its known lytic properties, MSI-78 also has a striking effect on ribosomes. MSI-78's effect on DSC scans of bacteria was similar to that of kanamycin, an antibiotic drug known to target ...
