الصلاة والعمل – الروح و حركة الجسد – تحول الطاقة

يعني لابد من الصلاة حتى يقبل العمل وكذلك

لابد من العمل حتى يكون للصلاة قيمة ….

يعني إحرص على أن تختم أي عمل بالصلاة حتى لو صلاة سنة تطوع

وإحرص على:

لاتأتي عليك صلاتين دون إنجاز أي عمل صالح تبتغي إحتساب الأجر في الآخرة

باختصار: إجعل للوقت قيمة بأن لا تمر عليك الصلوات وانت على الحال نفسها دون عمل صالح ….

نعلم أن الطاقة لها أشكال مختلفة و تحولاتها …. نحن نتكلم عن الطاقة الحركية مقابل الطاقة الحرارية –

Results of the World’s Largest Medical Study of the Human Mind a nd Consciousness at the Time of Death published

The results of a four-year international study of 2060 cardiac arrest cases across 15 hospitals published and available now on ScienceDirect. The study concludes:

  • The themes relating to the experience of death appear far broader than what has been understood so far, or what has been described as so called near-death experiences.
  • In some cases of cardiac arrest, memories of visual awareness compatible with so called out-of-body experiences may correspond with actual events.
  • A higher proportion of people may have vivid death experiences, but do not recall them due to the effects of brain injury or sedative drugs on memory circuits.
  • Widely used yet scientifically imprecise terms such as near-death and out-of-body experiences may not be sufficient to describe the actual experience of death. Future studies should focus on cardiac arrest, which is biologically synonymous with death, rather than ill-defined medical states sometimes referred to as ‘near-death’.
  • The recalled experience surrounding death merits a genuine investigation without prejudice.

Recollections in relation to death, so-called out-of-body experiences (OBEs) or near-death experiences (NDEs), are an often spoken about phenomenon which have frequently been considered hallucinatory or illusory in nature; however, objective studies on these experiences are limited.

In 2008, a large-scale study involving 2060 patients from 15 hospitals in the United Kingdom, United States and Austria was launched. The AWARE (AWAreness during REsuscitation) study, sponsored by the University of Southampton in the UK, examined the broad range of mental experiences in relation to death. Researchers also tested the validity of conscious experiences using objective markers for the first time in a large study to determine whether claims of awareness compatible with out-of-body experiences correspond with real or hallucinatory events.

Results of the study have been published in the journal Resuscitation and are now available online.

Dr Sam Parnia, Assistant Professor of Critical Care Medicine and Director of Resuscitation Research at The State University of New York at Stony Brook, USA, and the study’s lead author, explained: “Contrary to perception, death is not a specific moment but a potentially reversible process that occurs after any severe illness or accident causes the heart, lungs and brain to cease functioning. If attempts are made to reverse this process, it is referred to as ‘cardiac arrest’; however, if these attempts do not succeed it is called ‘death’. In this study we wanted to go beyond the emotionally charged yet poorly defined term of NDEs to explore objectively what happens when we die.”

Thirty-nine per cent of patients who survived cardiac arrest and were able to undergo structured interviews described a perception of awareness, but interestingly did not have any explicit recall of events.

“This suggests more people may have mental activity initially but then lose their memories after recovery, either due to the effects of brain injury or sedative drugs on memory recall,” explained Dr Parnia, who was an Honorary Research Fellow at the University of Southampton when he started the AWARE study.

Among those who reported a perception of awareness and completed further interviews, 46 per cent experienced a broad range of mental recollections in relation to death that were not compatible with the commonly used term of NDE’s. These included fearful and persecutory experiences. Only 9 per cent had experiences compatible with NDEs and 2 per cent exhibited full awareness compatible with OBE’s with explicit recall of ‘seeing’ and ‘hearing’ events.

One case was validated and timed using auditory stimuli during cardiac arrest. Dr Parnia concluded: “This is significant, since it has often been assumed that experiences in relation to death are likely hallucinations or illusions, occurring either before the heart stops or after the heart has been successfully restarted, but not an experience corresponding with ‘real’ events when the heart isn’t beating. In this case, consciousness and awareness appeared to occur during a three-minute period when there was no heartbeat. This is paradoxical, since the brain typically ceases functioning within 20-30 seconds of the heart stopping and doesn’t resume again until the heart has been restarted. Furthermore, the detailed recollections of visual awareness in this case were consistent with verified events.

“Thus, while it was not possible to absolutely prove the reality or meaning of patients’ experiences and claims of awareness, (due to the very low incidence (2 per cent) of explicit recall of visual awareness or so called OBE’s), it was impossible to disclaim them either and more work is needed in this area. Clearly, the recalled experience surrounding death now merits further genuine investigation without prejudice.”

Further studies are also needed to explore whether awareness (explicit or implicit) may lead to long term adverse psychological outcomes including post-traumatic stress disorder.

Dr Jerry Nolan, Editor-in-Chief of Resuscitation, stated: “The AWARE study researchers are to be congratulated on the completion of a fascinating study that will open the door to more extensive research into what happens when we die.”

 بينت نتائج الدراسات الشاملة التي أجراها الباحثون من جامعة ساوثهامبتون البريطانية، التي استمرت اربع سنوات، وشملت أكثر من 2000 مريض توقفت قلوبهم عن العمل، في 15 مستشفى في بريطانيا والولايات المتحدة والنمسا، بينت ان حوالي 40 بالمائة من الذين ماتوا سريريا وعادوا الى الحياة من جديد، يصفون بدقة كل ما جرى حولهم خلال فترة “الموت السريري” قبل عودة القلب الى نشاطه.

فمثلا يتذكر أحد هؤلاء (57 سنة) يعمل في منظمة اجتماعية بمدينة ساوثهامبتون، كيف غادر جسده وشاهد كل ما يقوم به الأطباء والممرضات بجسده، خلال الثلاث دقائق التي قضاها في حالة “الموت السريري”، حيث ذكر ذلك بصورة مفصلة، حتى أنه وصف الأصوات الصادرة عن عمل الأجهزة الطبية.

وحسب قول الباحث سيم بارني، من المعلوم ان الدماغ لا يقوم بوظيفته بعد توقف القلب عن العمل. ولكن هذه الحادثة تبين ان الوعي بقي مدة ثلاثة دقائق، على الرغم من أن الدماغ يتوقف عمليا بعد 20 – 30 ثانية من توقف القلب. واضاف، لقد وصف هذا الشخص بالتفصيل كل ما جرى في الغرفة، وانه سمع الاشارات التي يطلقها جهاز طبي كل ثلاث دقائق.

ويشير الباحث، الى ان الكثيرين لم يتمكنوا من تذكر تفاصيل معينة خلال وجودهم في حالة “الموت السريري”، وان كل خامس منهم تحدث عن الشعور غير الاعتيادي الذي لازمه في هذه الحالة. وان ثلثهم شعروا ببطء او تسارع الوقت، وبالخوف، وان 13 بالمائة منهم وصفوا كيفية مغادرتهم الجسد.

The 2014 Nobel prize in physics awarded to Japan

Isamu Akasaki and Hiroshi Amano at Nagoya University, Japan, and Shuji Nakamura of UC Santa Barbara have won for inventing blue light-emitting diodes, ‘a new, energy-efficient and environmentally friendly light source’

The invention of the blue LED was the final key to using light-emitting diodes – low power, long-lasting sources of light – in a panoply of different ways, which revolutionised countless technology sectors.

The Nobel Assembly itself focuses on the importance of blue LEDs to creating fully white light. White light is made from combining light from every other colour, but before blue LEDs, one crucial part of the spectrum was missing.

Now, by combining a blue, red and green LED, we can create even white light. You’ll recognise it from the glow of your smartphone screen, where the low heat output and slim size of LEDs are a selling point, or from the backlight of a newer LED TV, where the low power usage lets manufacturers trumpet cheaper electricity bills.

Increasingly, white LED lamps are replacing other sources of light. In the home, for instance, LED bulbs are becoming a popular alternative to traditional CFC ‘low power’ bulbs. They use even less power, and last even longer, than the old-style bulbs, can reach full brightness immediately, and are frequently even programmable to display different hues of light.

At dusk and dawn: Scientists pinpoint biological clock’s synchronicity

time1_500

Scientists have uncovered how pacemaker neurons are synchronized at dusk and dawn in order to maintain the proper functioning of their biological clocks. Their findings, which appear in the journal PLOS Biology, enhance our understanding of how sleep-wake cycles are regulated and offer promise for addressing related afflictions.

“We’ve known for some time that the time-keeping of our biological clocks is a complex enterprise,” says New York University’s Justin Blau, a professor of biology and neural science and one of the study’s co-authors. “But our results offer new details on how clock neurons work together to keep each other in check.”

The study, which may be downloaded here, also included researchers from the University of Michigan and the University of Houston.

They examined the biological, or circadian, clocks of Drosophila fruit flies, which are commonly used for research in this area—earlier studies of “clock genes” in fruit flies allowed the identification of similarly functioning genes in humans.

While scientists have a firm understanding of how biological clocks work within individual cells, it is less clear how individual cells tick in time together. Such an understanding is vital so that an organism has one coherent sense of time.

This dynamic was the focus of the PLOS Biology study.

The researchers focused on eight master pacemaker neurons (LNvs) located in the central brain —these neurons set the timing of the daily transitions between sleep and wake in the fly.

Specifically, they examined the signals coming in to these eight LNvs. The researchers found that LNvs need two synchronizing signals: they signal to each other at dawn and receive a signal from a second group of clock neurons at dusk. The LNvs start to desynchronize very quickly in flies lacking either of these synchronizing signals, showing how active and important this process is. And in flies lacking both of these signals, the LNvs show weak clock gene rhythms and disrupted sleep/wake cycles.

The researchers point out their findings shed new light on what occurs at dusk—and the significance of the timing of this signaling.

“Scientists already knew about the signaling at dawn, but we hadn’t previously known about the signaling that occurs in the evening,” explains Blau. “We can see how delicate this process is–and treatments to desynchronize clocks might even allow us to reset our clocks more quickly to a new time zone, which would be invaluable in jetlag.”

Diamond nanothreads

nano_500

Diamond nanothreads” promise extraordinary properties, including strength and stiffness greater than that of today’s strongest nanotubes and polymers. The core of the nanothreads is a long, thin strand of carbon atoms arranged just like the fundamental unit of a diamond’s structure — zig-zag “cyclohexane” rings of six carbon atoms bound together, in which each carbon is surrounded by others in the strong triangular-pyramid shape of a tetrahedron. The threads, made for the first time by a team led by John V. Badding of Penn State University, have a structure that has never been seen before.

خواطر فجرية

خطر لي خاطر:

كم سرعة الضوء ٣٠٠٠٠٠كم/ثانية

قال تعالى”وإن يوما عند ربك كألف سنة مما تعدون”

السنة عندنا ٣٦٥ يوم

والألف سنة عندنا٣٦٥٠٠٠يوم

اليوم (عند ربك) = ٣٦٥٠٠٠ يوم عندنا على الأرض

نسبة اليوم (عند ربك) / اليوم عندنا = ٣٦٥٠٠٠

يعني اليوم (عند ربك) هو اليوم الضوئي والسنة عند ربك (إن جاز القول) هي السنة الضوئية ……. صحيح ولا أنا غلطان؟!

خطر لي خاطر ثاني:

إذا علمنا أنه في اليابان الوقت نهار وفي نفس اللحظة اللي في أمريكا نايميين … صح

طيب احنا نعلم أنو على مدار الساعة على وجه الأرض في كل لحظة الصلوات الخمس كلها تؤدى اثناء هذه اللحظة … صح

نعلم ان هنالك ملائكة يتناوبون عليكم بالليل والنهار

يعني في كل لحظة هنالك حركة للملائكة تتبع حركة الشمس ….. صح

الله ينزل (نزولا يليق بجلاله) إلى السماء الدنيا في الربع الأخير من الليل فيقول من هل من مستغفر فأغفر له … هل من سائل فأعطيه ….. صح

طيب إذا فرضنا كانت الربع الأخير من الليل في اليابان ودعوت

وبعد ساعة مثلا كنت في الهند وكانت الربع الأخير من الليل ودعوت

وبعد ساعة في ايران وبعد ساعة في الرياض وهكذا وتدور الأرض ……

فالله قريب ويجيب القائمون المتهجدون طوال الوقت على الأرض أثناء دورانها … صح

وقال الله تعالى لا تسبو الدهر فأنا الدهر ….

ماذا تستنجون؟!
