However, the experts often face difficulties in the examination of such notes and authenticating the original author if such suicide notes are written on any unconventional surfaces i.e. surface other than usually used for writing. This difficulty is manifold increased when the writing on unusual surface is done by unconventional writing instruments. Forensic documents examiners (FDE’s) may come across such questioned handwriting which may have variations that are beyond the scope of natural variations and pose a challenge to the forensic document exa miner. This paper presents a review on forensic analysis of handwriting on unconventional surfaces by unconventional writing instruments.

The paper provide a simple method to evaluate fabricated documents in order to assist forensic document expert

Stains i.e. blood, semen, saliva, lipstick are the most common evidence found at the crime scene. Lipstick is one of the important type of evidence, which is mostly found on clothing’s, papers, tissue-papers, cigarette-buts, skin or any other surface or thing. In the present study an attempt has been made to analyze the Lipstick stains using new solvent system [isopropyl alcohol: acetone: distil water: amino solution (35: 35: 25: 5)] by TLC and paper chromatography, they are one of the best, economical, easily handle technique which can be used for the identification of lipstick smear. The ultra violet light and photo colorimeter can also used for placing link between suspect and question samples. For this total 17 samples of branded and local brands of red shade lipsticks were taken from consumers and purchase from the local market of Allahabad, Questioned lipsti...

But nowadays, most of the documents are exclusively electronically formed for better storage and efficient processing. Thus, digitalizing and hence making the field of Forensic Document examination to improve and go hand in hand with the trend as it has become very easy for a person to manipulate with any kind of document with the help of various image manipulation software. This paper refers the review of digital techniques used in the forensic analysis of the various kinds of documents. Also, the authors report that less work has been done on offline scanned documents and have suggested the need of use of latest Image Processing tools for the advancement of the related work.

In this paper, an attempt is made to provide an effective method of examination and comparison of signatures by using a computational technique. For various legal problems and in relation to their admissibility in court this computational approach is given which is used as a reflection of the true state of evidence and to strengthen ones observation regarding differences among the two specimens. The computational method of measuring pixel values of signatures based on distance and angle based classification of signatures with better accuracy. The performance of this system is then calculated on the basis of False acceptance range and False rejection range, graphical representations and statistical analysis and provide the better result. Achieved results suggested the adequacy of the selected features. The experimental results is presented with the conc...

However, handedness, and gender may be involved in the formation of this behaviour. Since handwriting is a complex and multi-causal mechanism.

By knowing the gender, the suspect list for a particular case can be shortened, which will facilitate the examination/investigation.

After examination of suspected vinegar sample it was concluded that all the samples were adulterated and did not follow the BIS standard.

This approval was based on evidence from FAME trials which were conducted at a time when ranibizumab was not available. There is a paucity of data on implementation of guidance on selecting patients for this treatment modality and also on the real world outcome of fluocinolone therapy especially in those patients that have been unresponsive to ranibizumab therapy. Retrospective study of consecutive patients treated with fluocinolone between January and August 2014 at three sites were included to evaluate selection criteria used, baseline characteristics and clinical outcomes at 3-month time point. Twenty two pseudophakic eyes of 22 consecutive patients were included. Majority of patients had prior therapy with multiple intravitreal anti-VEGF injections. Four eyes had controlled glaucoma. At...
