RELATION BETWEEN MINERALOGY, GEOCHEMISTRY AND DURABILITY OF SOME ALKALINE ROCKS, SOUTH EASTERN DESERT, EGYPT

The use of mineralogical characteristics, chemical analysis and mechanical characteristics in addressing the behavior of some alkaline rocks to resist weathering action is discussed in the present research paper.The alkaline rocks outcropping at two selected areas in the southern Eastern Desert, namely Hamrat Salma and Abu Khrug are studied.Field relation, petrography and chemical analysis of the rocks in areas, durability and unconfined compressive strength were done.Durability and unconfined compressive strength tests evaluate the resistance of the studied alkaline rocks to natural weathering.The studied alkaline rocks in both areas are classified mineralogically and chemically as trachyte, and syenite.In Hamrat Salma, the alkaline rocks are represented by trachyte, whereas in Abu Khrug area, they are discriminated to trachy-dacite and syenite.All the studied alkaline rocks have alkaline affinity and emplaced in anorogenic tectonic regime.The results of compressive strength and durability of Hamrat Salma trachyte and Abu Khrug syenite showed very strong strength.The lowest value was obtained from syenite with xenoliths and trachyte of Abu Khrug showing medium strength.Negative relation between uniaxial compressive strength and durability is recorded.The existence of xenoliths, veins and porphyritic texture create a weak relationship.There is a linear relationship between compressive strength and some major oxides (SiO 2 , Al 2 O 3 and Na 2 O) for the rock types.Also, a direct relation between durability and (Fe 2 O 3 , K 2 O) was recorded.

APPLICATION OF REMOTE SENSING AND AIRBORNE SPECTROMETRIC DATA ANALYSIS TO DELINEATE THE ALTERATION ZONES AT GABAL SUWAYQAT AREA CENTRAL EASTERN DESERT, EGYPT

The present study aims to study the potentiality of promised radioactive zones in the granitic rocks at Gable Suwayqat area.The Processed Landsat ETM+ data false color composite image (FCC) band 7, 4, 2 in RGB, band ratios (5/7, 4/3, 3/1), (5/7, 5/1, 4), (3/1, 5/4,7/5) in red green blue and 5/7 in gray color.Principal component analysis (Pc2, Pc3, Pc5) in RGB were prepared for discriminating rock unites.Verified by the fieldwork and airborne gamma-ray spectrometric surveyed data enabled to differentiate the acidic and mafic rocks, and identified the alteration zones in the granitic rocks, which were effectively distinguished into high felsic and low ferromagnesian mineral contents, relative to the other granite areas.The gamma-ray spectrometric interpretations reveal that most of radiometric anomalies recorded at north eastern and south western sides of study area.The structural framework and consequent surface features controled and managed the distribution and localization of the radioactive elements and the environmental dose rates in the area.The high fractures density act as good channels and passages for the mineral bearing hydrothermal ascending fluids and the percolating meteoric water that leached uranium mineralization and redeposited it in the adjacent fractured sites.Such processes in the granitic masses may be responsible for the presence of uranium and thorium mineralizations in these granites.The calculated dose rates range between 0.1 and 1.1m Sv/year, indicating that the study area remains safe and under the maximum permissible safe radiation dose rate without harm to the individual, with continuous external irradiation of the whole body.The results show that the target area has some eU, eTh, and K% anomalies related to the biotite granites and are structurally controlled by the dominated faults.
Privacy-Preserving Key-Updatable Public Key Encryption with Keyword Search Supporting Ciphertext Sharing Function

Public key encryption with keyword search (PEKS) allows a user to make search on ciphertexts without disclosing the information of encrypted messages and keywords.In practice, cryptographic operations often occur on insecure devices or mobile devices.But, these devices face the risk of being lost or stolen.Therefore, the secret keys stored on these devices are likely to be exposed.To handle the key exposure problem in PEKS, the notion of key-updatable PEKS (KU-PEKS) was proposed recently.In KU-PEKS, the users' keys can be updated as the system runs.Nevertheless, the existing KU-PEKS framework has some weaknesses.Firstly, it can't update the keyword ciphertexts on the storage server without leaking keyword information.Secondly, it needs to send the search tokens to the storage server by secure channels.Thirdly, it does not consider the search token security.In this work, a new PEKS framework named key-updatable and ciphertext-sharable PEKS (KU-CS-PEKS) is devised.This novel framework effectively overcomes the weaknesses in KU-PEKS and has the ciphertext sharing function which is not supported by KU-PEKS.The security notions for KU-CS-PEKS are formally defined and then a concrete KU-CS-PEKS scheme is proposed.The security proofs demonstrate that the KU-CS-PEKS scheme guarantees both the keyword ciphertext privacy and the search token privacy.The experimental results and comparisons bear out that the proposed scheme is practicable.
PALYNOMORPH BIOSTRATIGRAPHY OF THE SUBSURFACE DEVONIAN ROCKS, GHAZALAT BASIN, WEST QATTARA DEPRESSION, EGYPT

Well-preserved palynomorphs dominated by miospores and subordinate acritarchs and chitinozoans are recovered from some cuttings of Ie 11 -2 borehole drilled in the Ghazalat Basin in the west of Qattara depression, Egypt .A total of 36 species of palynomorphs (25species of spores, 8 species of acritarchs and 3 chitinozoan species) are identified.The palynological investigation of the studied stratigraphic interval enabled the recognition of three informal zones ranging in age from Lochkovian to Emsian.Most of the palynomorph taxa encountered are closely comparable with coeval assemblages recorded from North Africa, Saudi Arabia, Western Europe and Canada, indicating the close relationship of the present area to other parts of the western Gondwana and southern Euramerican provinces during that time interval.Frequent representation of marine taxa (acritarchs and chitinozoans) together with associated spores indicate near-shore marine depositional environment for the Lower and Middle Devonian (Zeitoun Formation) deposits in north Western Desert region of Egypt.

PETROLOGY AND GEOCHEMISTRY OF UM ESH OPHIOLITE SERPENTINITES, EASTERN DESERT, EGYPT: A NEOPROTEROZOIC METAMORPHOSED SSZ MANTLE

The Um Esh Neoproterozoic ophiolite serpentinites, Eastern Desert of Egypt, comprise massive and foliated varieties which are composed mainly of antigorite with accessory Cr-spinel.Carbonates are variable in abundance and represented by magnesite aggregates and veinlets.The Cr-spinels are usually zoned with fresh cores or relics surrounded by ferritchromite and chromian magnetite rims.The very low TiO 2 contents (<0.025 wt%) of primary Cr-spinel and the low Al 2 O 3 /SiO 2 values (0.010-0.016) of serpentinite samples are consistent with residual mantle which experienced high degree of partial melting.The Al 2 O 3 (16-25 wt%) and TiO 2 (average = 0.007 wt%) contents of the primary Cr-spinel overlap those of spinels of suprasubduction zone (SSZ) and mid-oceanic ridge (MOR) peridotites.However, the Cr# (0.55-0.66) and Mg# (0.39-0.59) of the fresh Cr-spinels together with depleted nature of the Um Esh serpentinites are similar to those of modern SSZ fore-arc peridotites.Profiles along zoned Cr-spinels revealed that Cr 2 O 3 , Al 2 O 3 and MgO abundances decreased abruptly, whereas FeO contents and Fe# (Fe 3+ /Cr+Al+Fe 3+ ) increased rapidly from fresh Cr-spinel through ferritchromite to chromian magnetite, with gradual change within the individual metamorphic spinel zones.On the other hand, the variation of MnO and NiO abundances is not regular from core to rim.The dominance of antigorite and the presence of metamorphic spinel rims suggest that Um Esh serpentinites have experienced prograde metamorphism up to lower amphibolite facies under oxidizing conditions.
The influence of the pedagogical technology for motivation development on the value self-determination of students with a high level of creative thinking

The problem statement. Contemporary education in Russia is faced with the task of introducing a humane approach in the training of a future specialist capable of adapting to changing living conditions. The aim of the paper in this perspective was to substantiate theoretically and study empirically the relationship between the value-motivational sphere of the personality and creative thinking of a young person. A theoretical analysis of works devoted to a creative approach in education has shown that internal motivation for educational activities is combined with motivation for a creative approach in solving educational problems. As a result of the experimental study, a significant relationship was revealed between the significance of the value of spirituality and an increase in the integral indicator of the creative thinking level, which indicates the orientation of a creative person to the search for inner harmony and their own destiny among young people.

Education in training courses in communication-oriented fields

This article considers the role of independent work in distance learning. Independent work of students is an integral part in modern teaching and learning process. At the moment, independent work in percentage terms for full-time education is up to 50%. The indicator increases significantly to 90% for extra-mural form of study. When determining the content and methods of independent work of students in the educational process, one should take into account the expected level of a certain set of graduates’ competencies, which should be achieved during the period of study, and which should be provided by their skills to build their own trajectory of development in a professional and personal format. In this paper special attention has been given to the potential of visualization as a traditional and, at the same time, exclusively modern means of methodological support.
Utilization of Blockchain Technology for Future Education

Blockchain is a distributed ledger that is both decentralized and distributed. There is a Node that acts to keep track of all transactions on the Blockchain across all networks. Due to the immutable or immutable nature of Blockchain technology, the risk of fraud is extremely low. In the realm of education, this is unquestionably a highly practical and safe technology for conducting digital certification, recording, and so on. It is envisaged that Blockchain technology would be able to tackle difficulties that frequently arise in the field of education. The blockchain-based educational architecture has enormous promise for minimizing the degree of cheating that is so prevalent in the educational environment. This study employed a multi-method approach, with the goal of examining Blockchain-based education design, Blockchain features used, and Blockchain-based educational services as a consequence of the study. Each of these areas is critical to the implementation's success.
GEOCHEMICAL CONTRIBUTIONS OF REE'S BEARING PEGMATITES, WITHIN KADABORA GRANITIC PLUTON, CENTRAL EASTERN DESERT, EGYPT

Pegmatitic bodies are encountered within the Kadabora granite to which they are spatially and genetically related.These bodies bearing REEs, U, Th, Y, Zr, Hf, Nb, Ta, and Cs.The mineralized pegmatites are characterized by high ΣREEs contents ranging from 3404 ppm to 15196 with an average of 7516ppm.The assemblage of the accessory minerals encountered in the mineralized pegmatites are zircon, allanite, fergusonite, uranothorite, betafite, samarskite, pyrochlore, bastnaesite, cerianite, rutile, euxenite and opaques.Each of these minerals is bearing certain trace elements ; zircon (Zr, Hf , Th); fergusonite (U, Th, Zr); uranothorite (Th, U); betafite (U, Nb, Ta); samarskite (Nb, Ta, U); pyrochlore (Nb, Ta); bastnaesite (REEs); cerianite (Ce, Th, Nb, Ta, Zr) and rutile (Ti).The REEs distribution pattern in the mineralized pegmatites reflects the role of these minerals as REEs accumulators e. g. betafite, bastnaesite and cerianite host LREEs while zircon, allanite and samarskite host HREEs.The REEs pattern is characterized by HREEs enrichment relative to LREEs with convex tetrad effect and a sharp negative Eu anomaly.This well demonstrated pattern reflects highly differentiated rocks associated with self strong hydrothermal interaction.It seems that parent magma has undergone extensive magmatic differentiation, during associated with syngenetic interaction of aqueous hydrothermal fluids resulted in the tetrad effect of REEs distribution forming highly mineralized pegmatites.
DISCRIMINATION OF LESS AND HIGH FRACTIONATED GRANITIC ROCKS, BY WEATHERING SCHEME, BIRIRIG AREA, CENTRAL EASTERN DESERT, EGYPT.

The granitic rocks in Egypt cover more than 40% of the total area of the basement rocks, many efforts were exerted aiming to classify the granitic rocks in Egypt.The present work classifies the Biririg granitic rocks, in the central Eastern Desert of Egypt, on the basis of their mineralogical and chemical composition and discusses the effects of different grades of weathering on their mineralogical and geochemical characteristic.Geochemically, the Biririg granitic rocks (BGR) were derived from calc-alkaline peraluminous parental melts as revealed from agpaitic index, modified alkali-lime index and the aluminum saturation index.Based on geochemical characteristic, the BGR are classified into less fractionated pinkish white granite (LFG) mainly hornblende biotite granite, and highly fractionated pink granite (HFG) mainly biotite granite, the later is evolved, through fractional crystallization from more basic and calcic melts.The BGR were evolved at active continental margin regime, as the geochemical characteristics of the BGR exhibit three main sources of enrichments namely subduction zone, convicted mantle wedge and sub-continental lithosphere.This research discusses, further, the relation between grade of weathering and engineering-pathological properties of the granitic rocks exposed in Biririg area.The chemical index of alteration (CIA) values revealed that, both of LFG and HFG are low weathered, with slight increase of weathering towards the less fractionated pinkish white granite.The pinkish white granite is more basic than pink granite, as the former exhibits more mafic constituents represent about 8% of the total rock volume and are mainly biotite with less frequent amounts of hornblende.The BGR were classified into WI and WII according to the grade of weathering, where the mineralogical, chemical and engineering properties changed.Most elements redistribute in their newly formed secondary minerals.The differences observed in the composition of the WII samples relative to the slightly weathered WI ones, could be attributed to the fractional crystallization of melt, original magmatic features and/or crustal contamination.
A new Connected Component Analysis based System for Text Segmentation in Degraded Historical Document Images

Historical documents contain valuable heritage information. These documents are preserved in the manuscript preservation center and archaeological departments. They are mostly degraded in nature and hence hard to read and understand the contents. So, there is a need for text segmentation and feature extraction to convert these manuscripts into machine editable format. In this work, we present an effective way to segment historical document images into characters. It is a challenging segmentation process due to complex background images. In this paper, horizontal histogram, vertical histogram and connected component analysis is used to segment text documents images. In this algorithm, the input image is converted to gray scale image, then gray image is converted into binary image [Otsu’s method] and then all the objects containing fewer than desired pixels are removed. Line and word segmentation is implemented using horizontal and vertical histogram method respectively. Then the connected components are labeled and properties are measured for the image regions. Connected component analysis is used to segment the characters and the individual characters are extracted. The simulation result shows that the proposed segmentation method achieves an average accuracy of 93.37% for HDLAC 2011 DATASET. Moreover this method is more efficient and more suitable for real time tasks.
ORGANIC CARBON ISOTOPE PERTURBATIONS IN THE CRETACEOUSPALEOGENE ORGANIC-RICH SEQUENCE, CENTRAL EGYPT

The Cretaceous-Paleogeneorganic-rich sediments of central Egypt are preserved as laterally extensive organic-rich successions that are represented mainly by the Duwi and Dakhla formations.Numerous studies were concerned their hydrocarbon source rock potential, trace metal accumulation, and molecular fossils composition.Very rare studies were concerning their organic carbon isotopic composition.The present study; however, investigates the δ13 C of bulk organic matter as well as the δ 13 C of primary productivity tracers (pristane and phytane) for samples from two drilled cores in the Quseir and Abu Tartur areas.The results of the δ13 C TOC values indicate that the organic carbon, is essentially derived from a mixture of C3 land-plants and marine plankton.The short-term variability in the δ 13 C TOC and δ 13 C TOC of the pristane and phytane across the Duwi Formation is mostly related to paleoecological factors and photosynthesis.The uppermost Duwi/lowermost Dakhla strata, which represent a maximum flooding surface, show a negative δ 13 C TOC of magnitude -1 to -2‰ and -4 to -6‰ in the bulk organic carbon and bioproductivity tracers, respectively.Such perturbation can be most probably related to density stratification and overturn, although more investigations are required for the different hypotheses.
