atmospheric pressure plasma (app) is an emerging non thermal technology for the improvement of food  safety. non-thermal plasma (ntp) is a neutral ionized gas that comprises highly reactive spices including, positive ions, negative ions, free radicals, electrons, excited or non excited molecules and photons at or near room temperature. ntp can be generated at atmospheric pressure that makes it ...

some cases of male infertility are due to the destructive side-effects of anticancer treatment methods such as chemo and radiotherapies on germ cell lines. the increase in the survival rate of cancer patients who undergo treatment, especially children, has drawn attention to fertility preservation. the most common and effective technique in preserving male fertility is sperm freezing and its su...

background : appropriate methodology for storage biological materials, extraction of dna, and proper dna preservation is vital for studies involving genetic analysis of insects, bacteria, and reservoir hosts as well as for molecular diagnostics of pathogens carried by vectors and reservoirs. here we tried to evaluate the utility of a simple filter paper-based for storage of insects, bacteria, r...

The creation of a concrete plan for preserving a collection of digital objects of a specific institution necessitates the evaluation of available solutions against clearly defined and measurable criteria. This process is called preservation planning and aids in the decision making process to find the most suitable preservation strategy considering the institution’s requirements, the planning co...

In this paper we describe the National Library of New Zealand’s attempts to conceptualise how we measure the degrees of effort required to achieve acceptable levels of digital preservation. We argue that understanding digital preservation practice in terms of “optimal effort” may help us conceptualise where and how best to achieve the greatest impact in proportion to effort. The paper examines ...

While most of researches focus on resolving the syntactic consistency problem in real-time collaborative graphics designing system, the semantic preservation problem should not be neglected. Graphics are created with user’s meanings. These meanings should be notified to other users and should not be arbitrarily modified by others. In this paper, we resolve the semantic preservation problem by f...

Objective To review and assess the ideal length of electrode in cochlear implant patients for hearing preservation. Methods The English language literature was reviewed for studies including hearing preservation and speech understanding for electrodes of different lengths. Results One prospective trial was found, and there were no studies that randomized patients into different length elect...

This paper addresses the question: What would distributed digital preservation look like using the OAIS Reference Model? The challenge is the need for several organizations to cooperate to achieve distributed digital preservation; using replication, independence, and coordination to address the known threats to digital content through time. The main purpose of the paper is to present an Outer O...

If not for the Internet Archive’s efforts to store periodic snapshots of the web, many sites would not have any preservation prospects at all. The barrier to entry is too high for everyday web sites, which may have skilled webmasters managing them, but which lack skilled archivists to preserve them. Digital preservation is not easy. One problem is the complexity of preservation models, which ha...

There are relatively few digital preservation policies within institutions: is digital preservation a subject of no importance? This paper presents ongoing work and findings from a JISC funded study on institutional digital preservation policies which aims to provide an outline model for digital preservation policies and in particular to analyse the role that digital preservation can play in su...
