ملحمة بطلها الملياردير المصري صلاح عطية
بداية الحكاية :
المكان : بلدة صغيرة اسمها [ تفهنا الأشراف ] بمركز ميت غمر التابعة لمحافظة الدقهلية من مصر
القصة : كان هناك تسعة أفراد بقرية صغيرة تخرجوا من كلية الزراعة يعانون من فقر شديد يريدون بدء حياتهم العملية فقرروا بدء مشروع دواجن حسب خبراتهم العملية وكانوا يبحثون عن شريك عاشر ..
في النهاية جمع كل واحد منهم مبلغ 200 جنيه مصري وهو مبلغ ضئيل جدا لكنه بنظرهم كبير .. باعوا به ذهب زوجاتهم أو أرض أو اقترضوا ليكمل كل واحد منهم مبلغ 200 جنيه وظلوا يبحثون عن الشريك العاشر حتى يبدأوا الشركة لكن لا جدوى ..
جاء أحد هؤلآء الشركآء واسمه المهندس صلاح عطيه (بطل القصة) وقال وجدت الشريك العاشر ..
فردوا جميعا من هو ؟
قال : هو الله .. وله عشر الأرباح في مقابل أن يتعهدنا بالحماية والرعاية والأمان من الأوبئة .. فوافق الجميع وتم كتابة عقد الشركة وتسجيله ..
مرت الدورة الأولى من المشروع والنتيجة : أرباح لا مثيل لها وانتاج لم يسبق له مثيل ومختلف عن كل التوقعات ..
الدورة الثانية من المشروع : قرر الشركاء زيادة نصيب الشريك العاشر [ الله ] إلى 20% ، وهكذا كل عام يزيد نصيب الشريك العاشر حتى اصبح 50% ..
اﻵن .. كيف تصرف أرباح الشريك العاشر ؟
تم بناء معهد ديني إبتدائي للبنين ..

LEVELLING OF RESOURCES_ Dr TALAAT REFAAT_Dr MOHAMED ISMAIL
This paper titled: LEVELING OF RESOURCES was introduced through an International Symposium titled: Project Planning & Implementation in Developing Countries at Cairo Feb. 20-23, 1984.
The Symposium was organised by International Project Management Association and Egyptian Society of Engineering.
The resource scheduling Algorithms are designed to provide effective work schedules and efficient use of resources. These are closely related, since poor schedule will lead to poorly used resources and increased costs.
Using flexibility in the timing of non-critical activities, the resources can be leveled without affecting the overall project time. The degree of flexibility is indicated by the amount of total float linked to the non-critical activities.

The amount of people in Arab Nations holding a B.Sc., B.A., Diploma, M.Sc., and Ph.D. is huge (1), most of which include a project/research applying or explaining the theoretical part of the thesis. Unfortunately most of them do not reflect a real problem or contribute in solving an existing problem. Therefore you can detect hundreds of thousands of thesis and research works being kept on the shelf unutilized.
On the other hand a huge number of organizations with different categories such as manufacturing, service, education, health care, nonprofit, etc.; have severe problems needing to be solved. In addition to another big problems that are facing our Arabic Communities such as unemployment.
Due to the absence of central planning, an accumulation of the above mentioned issues has caused a severe gap between the actual community requirements and the academic and research work. Each of community and academia are now isolated in a separate island. This isolation has caused another problem that is the gap between academic curriculums and needs of labor market. The new problem causes inadequacy of most graduates to labor market needs, and thus enroll them into the convoy of unemployment.

Slide 1: Title Slide
Extrachromosomal Inheritance
Slide 2: Introduction to Extrachromosomal Inheritance
Definition: Extrachromosomal inheritance refers to the transmission of genetic material that is not found within the nucleus.
Key Components: Involves genes located in mitochondria, chloroplasts, and plasmids.
Slide 3: Mitochondrial Inheritance
Mitochondria: Organelles responsible for energy production.
Mitochondrial DNA (mtDNA): Circular DNA molecule found in mitochondria.
Inheritance Pattern: Maternally inherited, meaning it is passed from mothers to all their offspring.
Diseases: Examples include Leber’s hereditary optic neuropathy (LHON) and mitochondrial myopathy.
Slide 4: Chloroplast Inheritance
Chloroplasts: Organelles responsible for photosynthesis in plants.
Chloroplast DNA (cpDNA): Circular DNA molecule found in chloroplasts.
Inheritance Pattern: Often maternally inherited in most plants, but can vary in some species.
Examples: Variegation in plants, where leaf color patterns are determined by chloroplast DNA.
Slide 5: Plasmid Inheritance
Plasmids: Small, circular DNA molecules found in bacteria and some eukaryotes.
Features: Can carry antibiotic resistance genes and can be transferred between cells through processes like conjugation.
Significance: Important in biotechnology for gene cloning and genetic engineering.
Slide 6: Mechanisms of Extrachromosomal Inheritance
Non-Mendelian Patterns: Do not follow Mendel’s laws of inheritance.
Cytoplasmic Segregation: During cell division, organelles like mitochondria and chloroplasts are randomly distributed to daughter cells.
Heteroplasmy: Presence of more than one type of organellar genome within a cell, leading to variation in expression.
Slide 7: Examples of Extrachromosomal Inheritance
Four O’clock Plant (Mirabilis jalapa): Shows variegated leaves due to different cpDNA in leaf cells.
Petite Mutants in Yeast: Result from mutations in mitochondrial DNA affecting respiration.
Slide 8: Importance of Extrachromosomal Inheritance
Evolution: Provides insight into the evolution of eukaryotic cells.
Medicine: Understanding mitochondrial inheritance helps in diagnosing and treating mitochondrial diseases.
Agriculture: Chloroplast inheritance can be used in plant breeding and genetic modification.
Slide 9: Recent Research and Advances
Gene Editing: Techniques like CRISPR-Cas9 are being used to edit mitochondrial and chloroplast DNA.
Therapies: Development of mitochondrial replacement therapy (MRT) for preventing mitochondrial diseases.
Slide 10: Conclusion
Summary: Extrachromosomal inheritance involves the transmission of genetic material outside the nucleus and plays a crucial role in genetics, medicine, and biotechnology.
Future Directions: Continued research and technological advancements hold promise for new treatments and applications.
Slide 11: Questions and Discussion
Invite Audience: Open the floor for any questions or further discussion on the topic.

(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.

Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.

Spectroscopy is a branch of science dealing the study of interaction of electromagnetic radiation with matter.
Ultraviolet-visible spectroscopy refers to absorption spectroscopy or reflect spectroscopy in the UV-VIS spectral region.
Ultraviolet-visible spectroscopy is an analytical method that can measure the amount of light received by the analyte.
Multi-source connectivity as the driver of solar wind variability in the heli...
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.
Structural Classification Of Protein (SCOP)
A brief information about the SCOP protein database used in bioinformatics.
The Structural Classification of Proteins (SCOP) database is a comprehensive and authoritative resource for the structural and evolutionary relationships of proteins. It provides a detailed and curated classification of protein structures, grouping them into families, superfamilies, and folds based on their structural and sequence similarities.
