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 Aqaba complex located at the southeastern of Jordan, exposes coexisting mafic-felsic association typical of syn-to pre-plate collision magmatism. The bulk of the pluton is made of quartz monzonite, granite and granodiorite. New U-Pb zircon dating revealed a synchronous emplacement of the granite (605 ± 4.6 and 617±3.7 Ma), granodiorite (613 ±4.4, 612 ±3.6 and 611.8±4.9 Ma) and quartz monzonite (608± 5.4 Ma). The whole-rock geochemistry indicate that the source for the quartz monzonite, granite and granodiorites could have been a continental arc-derived from mantle sources and mature metagreywackes. Melting of this crustal material was subduction related , which could have been an enriched mantle-derived melt contaminated. The Aqaba complex is a part of a the Arabian-Nubian Shield (ANS) are juvenile in character, Neoproterozoic, including in addition five large plutonic suites ; Rahma , Darba , Rumman,Urf and Yutum suite. The genesis of these suites were likely induced by mantle-derived magma in the shallow crust while their spatially and temporally discrete emplacement at shallow levels was probably related to the (extensional) of lithospheric boundaries, which represent a feasible fertile source for such granitoids.
