DNA, RNA, and protein are represented as strings in bioinformatics for this reason string processing is the cornerstone in the field of bioinformatics and these problems take a variety of manifestations each of which has a specific meaning. This topic will shed some light on some traditional string problems such as: local sequence alignment problem, global sequence alignment problem, exact pattern matching problem, approximate pattern matching problem, finding all maximal palindromes problem, finding all tandem repeats problem, finding all tandem arrays problem, etc. There are quite rich researches for these problems. This paper, will propose the major algorithms in this respect which implemented in BioQt.

The aim of this study was to investigate the response of broilers fed on test diets containing non-antibiotic growth promoters; Probiotic (BioPlus 2B), Prebiotic (TechnoMos), Synbiotic, and medicinal herbs (Mixture of Origanum majorana, Foeniculum vulgare, and Carum carvi in ratio 1: 1: 1), each within two dietary protein levels (normal and low), on these broiler performance. The study was carried out at the Poultry Research Center, Faculty of Agriculture; Alexandria University, Egypt. The experimental period lasted for 42 days. A total number of 500 days from Cobb broiler chicks, with similar average live body weight, were randomly distributed into 10 treatments. Each treatment comprised of 5 replicates of 10 chicks each. Ten experimental diets were formulated to be approximately isocaloric and cover all nutrients required for broiler throughout two stages of growth periods, starter diets (1-21) and finisher diets (22-42) days of age. Ten experimental diets were consisting of two levels of crude protein (recommended or low (85% of recommended)) and five feed-additive programmes (control, probiotic, prebiotic, synbiotic and medicinal plants). In general, feeding broiler lower crude protein levels (-10% of NRC) resulted in poorer growth performance, which was partially compensated with the non-antibiotic additives. Among the additives, synbiotic had positively significant effects on FCR, BW.

Global population is growing rapidly. As a result, increasingly large areas are being settled and

farmed. This devastates soils and causes pollution by heavy metals and other components. Heavy metals in

the environment originate from both natural and anthropogenic sources. Natural sources generally include

rock weathering and the propagation of heavy metals, such as Cr and Ni, from ultrabasic rocks. These are natural

processes that generally do not threaten human health. Anthropogenic sources include industry and inappropriate

disposal of waste in the environment. In such cases concentrations of heavy metals can be harmful

to people and other living beings. Al Zintan is a city located in northwestern Libya, on a plateau mainly built

up of Cretaceous sediments. Since the 1980’s, nomadic population has rapidly been settling this area. As a

result, a former part of the desert was transformed and is used for farming. Soil sampling at Al Zintan was

conducted in 2017, across a 2×2 km grid. A total of 143 samples were collected from depths of about 30 cm.

The samples weighed 2 to 2.5 kg and generally comprised sand with a clay component. A Niton Xl3t goldd+

instrument was used for chemical analyses, based on which GIS heavy-metal distribution maps were generated.

The distribution of Cr, Ni, Cu and Zn is discussed on the paper.

 The aim of the present paper is to develop a generalized fractional kinetic equation involving generalized multi-variable Mittag-Leffler function. Using the Laplace transform, the solutions of the fractional kinetic equation are established in terms on general Mittag-Leffler function. The results obtained here are general in nature to yield a large number known and (presumably) new results as their special cases.
