SLEEP PARALYSIS

Aroona Kunwor, Khce
27 JUNE 2017

Have you ever woke up amidst your sleep and wished that you hadn't because you were aware that you already woke up but the problem is: neither you could move your body nor speak or shout against the feeling of anxiety and chocking due to huge apparent weight on your chest or someone giant holding you down?

If the answer is "NO", then I pray that you never had one, ever in your lifetime. For those whose answer is "YES", dont worry. It's not that serious and devastating disorder of your body though. In medical language, it is called 'Sleep Paralysis'.

Fig:Drammatic depiction of sleep paralysis
Again the word 'Paralysis', lingering with the word 'Sleep' may frighten you more. Believe me, its literally same as we may infer from the word combination 'Sleep Paralysis', however differing in the fact that one who has already had once, or has frequently have more than once, they believe it ,indeed!

WannaCry: The Data Kidnapper

Ayush Bhattarai
Executive, ACM Foundation
We live in a world where communication has become a major part of people’s lifestyle. Without communication the existence of the world we live today would be impossible. As the saying goes, “With great power, comes great responsibilities” the process of making these communication secure become more and more difficult each day. With new methods of breaching into people’s private information and accessing data illegally the challenge of “Counter-Hacking” has become more and more difficult. Lately a ransomware called WannaCry or wcry has been in the radar of the international cyber security society. Its notorious actions have caused damage to more than 230,000 computers in more than 150 countries worldwide and is spreading rapidly.


What is a ransomware?
A ransomware is a computer malware which encrypts the files on a computer system and asks for ransom to decrypt the files. In other sense ransomware can be identified as the kidnapper of computer files and asks for ransom to let your data free. A ransomware works under the knowledge of cryptovirology i.e. the use of cryptography to create malwares. The use of cryptovirology has been increasing day by day as new algorithms to encrypt are published regularly.

History of WannaCry
National Security Agency(NSA) of the United States of America had found a way to exploit the vulnerability of the SMB (Server Message Block) protocol of the Microsoft Windows OS. The exploit called EternalBlue grabbed hold of Microsoft’s collar and was breaching into people’s messages and emails. A group of hackers known by the name “Shadow Brokers” leaked the exploit and the methods which caused a huge outcry on the internet. After the leak of the exploit done by the NSA, computer hackers started developing a new ransomware which infected the computer through attached email files pretending to be legitimate and encrypting the data in the computer. This new project was called “WannaCry”. WannaCry started to spread with a huge bang. After its release on 12 May 2017, it started infecting more than 230,000 within a day. WannaCry demands $300 equivalent Bitcoins in the form of ransom within 3 days of encryption and after that the ransom will rise. After 7 days if failed to submit the ransom, WannaCry will erase all the data from the computer. Bitcoin which is demanded for ransom is a type of cryptocurrency which works by securing transactions by various cryptographic algorithms and returning units of digital currency. Bitcoin was invented in 2009 by a programmer or a group of programmers under the name Satoshi Nakamoto.

How does WannaCry work?
As stated earlier a ransomware demands for ransom in exchange for the freedom of the data. So, WannaCry does the same. Initially, WannaCry is attached to an email which looks legitimate and is sent to the target computer user. As soon as the email is opened, WannaCry installs DoublePulsar which is an exploit tool developed by the NSA onto the system and encrypts all the data except for two files i.e. the ransom note and the directions to buy Bitcoins. WannaCry has affected major international companies like FedEx, Renault, Nissan, Bank of China, Hitachi etc. and have caused severe damage worth millions.


Is there a solution?
A “white-hat” hacker accidentally triggered the “killswitch” of WannaCry after he discovered a URL in the malware and registered it which shut the ransomware and stop its spreading. But soon WannaCry got updated and the killswitch no longer worked after registering the URL.
So, the best way to stay safe from WannaCry is firstly to keep all data backed up. Keeping backup data can be very useful because situations where erasing of data might happen and other various factors. Second, not to open emails from unknown sources or verify the emails by cross checking if sent (it might pretend to be your boss) by someone you know.

Thus, WannaCry has caused a major headache to the cyber security society due to its sneaky behavior and its encryption method. And people affected by WannaCry are URGED NOT TO PAY THE RANSOM, because if paid it will encourage the hackers to do more stuffs like this and nobody’s data or privacy will remain private.

बोकापंथी

बोका गनाउछ....
सायद त्यसैले केटाहरुलाई बोका भनिन्छ !!
तर म आज गनाउने बोका नभई सुगंदित बोकाहरू र तिनको बोकापंथी केलाउदै छु।  केटा केटि प्रति र केटि केटा प्रति आकर्सित हुनु स्वाभाविक कुरा हो तर आजको यो समयसम्म आईपुग्दा केटि प्रतिको आकर्सनले बाहुल्यता पाएको देखिन्छ।


एक बचन मिठो बोल्नु हुन्न  , सर्बसै पुग्छ !!
खित्त दात देखाएर हास्नु हुन्न , भुतुकै हुन्छन !!!
फेसबुकमा केटिको Friend Request देख्नु  मात्रै पर्छ , ढल्छन् बोकाहरू !!!
सबैभन्दा बढी बोकपंथी झल्कन्छ facebook भित्ताहरुमा...

RAM " माया खै कसले बुज्यो " - 10  Like , 2 Comments (10 Hours)
RADHIKA " माया खै कसले बुज्यो " - 1.2K  Like, 222 Comments (2 Hours)

र यसैलाई भनिन्छ बोकापंथी !!!
करिब २ -३ महिना देखी जब जब यस्तो देख्छु तब तब माथिको फोटो कमेन्ट गर्ने गरेको छु र आगामी दिनमा पनि काएम राख्ने छु !!!
न त म कसैलाई परिभाषीत गर्न याे लेख्दै छु न त कसैलाई निरुत्साहीत। केटि प्रतीकाे आकर्सण स्वभाविक थयाे, छ र भाेली पनि हुनेछ। हरेक ठांउमा महिला भन्ने शब्द वा पात्र जाेडिने वित्तिकै त्यसले विषेश स्थान पाउंछ। यसकाे कारण महिलाहरुकाे बेजाेड समर्थन पक्कै हाेईन तर पुरुषहरुकाे लचकतापन भने अवश्य हाे।

 तर आजकाे याे समयमा यसकाे पूर्ण फाईदा भने महिलाहरुले लिन सकेका छैनन् । बढि जस्ताे महिलाहरु क्षणिकतामा रमाउने गर्छन्। छाेटा कपडामा सजिनु, उताउला सन्देश प्रवाहा गर्नु, सधै नाटकिय माया प्रेमका कुरा गर्नु, बनावटि र दाेअर्थीय कुरा गर्नु अादि ईनका उदाहरण हुन्। यी कुरा दैनिक रुपमा सामाजीक संजालमा देख्न पाईन्छ। र यीनै कुराहरु मै लठ्ठीने बाेकाहरु जमात पनि निकै ठूलाे छ। प्राय यसरी लठ्ठीनुकाे लक्ष्य कि त सम्बन्ध गांस्नु हुन्छ, कि त केटिलाई impress गर्नु हुन्छ या टाईम पासका लागी हुन्छन् ।
मेराे आशय कसैलाई उसकाे अधिकारबाट वञचित गर्नु हाेईन । बाेकाहरुलाई त मेराे भन्नु केही छैन तर महिलाहरुलाई भने केही भन्न चाहें: 
पहिलाे कुराे तपाई महिला हुनुमा गर्व गर्नुस्। कहिल्यै पनि काेही भन्दा कम नभएकाे अनुभुती गर्नुस्। मन, दिमाग र वाह्य स्वरुप, तिन्टै कुारालाई सिङ्गार्नुस् । र बस तपाईलाई याे समाजमा लड्न पुग्ने औजारहरु आफै सिर्जीत हुने छन्। क्षणिकतामा रमाएर हाेईन कालान्तर साेचेर आफ्ना कुराहरु राख्नुस् । क्षणिकतामा रमाउने धेरै हुनेछन् तर प्रसंसक नियुन हुनेछन्। आफ्नाे सुन्दरतालाई साेच र उपस्थीतीले ब्खयाउनुहाेस् न कि आफुलाई सुन्दरताले । यी बाेकाहरुलाई क्षणीकताका लागी प्रयाेग गर्ने हाेईन कातान्तर सम्मकालागी तपाईकाे चिन्तक बनाउनुहाेस्। 
अन्तममा यही भन्छु बाेकापन्थी तपाईका लागी बर्तमान समाजमा लड्न एउटा गतिलाे हतियार हाे। यसलाई अपनाउनुस् र पूर्ण लाभ लिनुस् !!!!

What would happen if earth stopped spinning?

Hi !!
You will know the importance of this question after reading this.
I used to ask this question to my classmates,

"What would happen if earth stopped spinning? "


The answers I used to get:

  1. World will be divided into two parts i.e one will be dark forever while other will be bright.
  2. There won't be any weather changes. etc.


But there will be much more massive things happening if earth stops rotating. You may not believe that whole Asia would be swept away by the flood/waves coming from pacific ocean and whole Africa would be devastated by huge waves generated from Indian Ocean.

There is a simple logic behind it. Earth is moving at an speed of 1100 MPH which is 5 time the maximum speed recorded in formula 1 racing. If the Earth stopped spinning suddenly, the atmosphere would still be in motion with the Earth's original 1100 mile per hour rotation speed. This speed of wind will clean up anything on its way which is not attached with the bedrock of the earth. It means that all the houses, trees, top soil and pretty much everything including you and your mobile will be flying on the atmosphere.
If you think you will not be affected with the speed of wind then wait, there is more than that. Suppose you are on a bus travelling at speed of 40 kmph and if it suddenly stopped, you will be pushed forward by significant distance.
Now take earth as a bus with a speed of 1100 mile per hour (around 1700 kmph) and if it stops suddenly, where will you be ?
A calculation shows that we would be thrown into the wall at speed of 1.5 times the speed of sound had wall been there.
This shows that everything will be swept away and this excessive force might even break the earth apart.
So it can be said that HUGE AND MASSIVE UNIDIRECTIONAL EARTHQUAKE will occur.
Life would end and there will be new start....
But who cares, we live in this earth for 100 years....the probability for such an event is practically zero in the next few billion years !!!!
So, cheers and enjoy your life...

Possible remedies for burning issue of Kathmandu roads: Dust generation

Suraj Shah, Khce

Dust arising from development is additional to background dust concentrations. If not adequately controlled dust emissions from developments may lead to increases in dust concentrations beyond the site boundary, which may affect local amenity and influence local air quality.
It is more effective to address dust emissions at the design and planning stage of new development proposals, than to seek to deal with dust problems retrospectively. Likewise it is more effective to deal with potential dust emissions at source, rather than once airborne. However, in context of Nepal system, the solution is searched once problem is in its high phase and it becomes the headlines of national daily. So, as an engineering student I am writing some major remedies  with their economic value to dust generation which is becoming a major health issue to Kathmandu valleys people.



They are as follows:

WATER:
Water is considered as one of the cheapest method for dust control but with the frequent application rates and equipment used in spraying and scarcity of water in context of valley its optional has to be thought. In generally, the effectiveness of water spray depends upon weather and traffic and may be effective from 30 minutes to 3 hours.so with the frequent application cause rise in capital and cause way slippery and cause potholes. If water is used as dust palliatives it should be used with surfactants or wetting agents or mix with less salts.

HYGROSCOPIC SALTS:
It may be next option for valley as water is scare  in a dry period generally (falgun to jesth) hygroscopic salts are typically chloride salts and suppress dust by attracting moisture from the air, keeping the road surface moist. They are generally applied as surface sprays or mixed in, followed by a final wash (rates vary according to material type, preparation and traffic). When the atmospheric moisture falls below 70% relative humidity, the hygroscopic chlorides cease to function, whereas the deliquescent chlorides cease to function at about 30–40% relative humidity. The products are thus climate sensitive, and Jones (1998) reports their limitation to a climate region encompassing Gauteng Chloride salts are able to have their water-attracting functions recharged with a few hours of adequate moisture and humidity.

PETROLEUM RESIN:
 The next solution is Petroleum (emulsified or sulphonated petroleum) resins are derived as a by-product of the oil refining industry; emulsified petroleum resins are formulated as dust suppressants and stabilizers. Binding agents added to the emulsified petroleum resin (derived from paraffinic crude oil) formulation, which penetrate the wearing course and bind the material, preventing them from becoming airborne. In addition, wetting agents, emulsifiers and dispersants are added to increase the penetration and spreading of the product.  The application methodology is dependent on the wearing course material characteristics, usually an initial mix-in application would be required followed by maintenance spray-on applications.

TAR AND BITUMEN EMULSION PRODUCTS:
The last discussed technical solution is Tar-based products are derived from coal tar distillates to which solvents are added to improve penetration. Bituminous based products are based on 80/100 penetration grade bitumen with solvents added. Emulsifiers and wetting agents may be added to enable the product to be mixed with water and applied as a mix-in product, followed by spray-on maintenance applications, at an application frequency and dilution dependent on the product itself, material type, preparation and traffic types and volumes. The palliative works by binding the wearing course material, but performance is sensitive to the quality of the wearing course material.

The graph showing comparisons of these products:

However other technique like traffic management ;reducing speed ,reducing traffic volume.

SOLUTION TO CONTROL DUST IN KATHMANDU

Air pollution has become a serious problem in Kathmandu Valley. It is normal that there will be high amount of dust in dry weather but the ongoing work of road extension and Melamchi Pipeline laying have made it worst.
There are lots of news about it, campaigns are done to make government awake about the issues and its being talked everyday in social media. Though, campaigns are done to force government, it hasn't bought any solution. People are investing their time in mass demonstration and advertising their campaigns instead of discussing and bringing out solutions.
The problem isn't only the dust due to construction activities, it is due to over population, increasing industries and heavy traffic which have been emitting carbon dioxide and toxic gases at alarming rate.



SO, I have proposed some solutions for this problems:

1) SPREADING WATER
 The immediate solution to dust is WATER. Water can be spreaded on the roads at the intervals of few
hours by trucks. For example: Koteshowr-Kalanki is the most dusty road in Kathmandu. The dust on the air is not due to ongoing work but due to the movement of vehicles on dusty road. So, spreading water on the existing road will certainly reduce the dust on air.
Same things can be done on other parts of Kathmandu.
Engine oils, chloride slats can also be used for more efficiency but it will be expensive to spread them for longer span.

2) WORKING AT NIGHT
Second solution to the dust would be WORKING AT NIGHT. The excavation of road surfaces increases dust on air. If it is possible, the excavation work should be done at night when temperature will be low and traffic will be less. Not only excavation, transportation of construction materials and their placement should also be done at night.
(If you have ride a bike and had been behind a truck carrying sand/soil, you must have seen the amount of dust it emits )

3) TRAFFIC REGULATION
As mentioned in no. 2, permitting trucks and delivery vehicles only at night time can be a solution. Similarly, regulation of school buses, delivery vans, private vehicles etc. for specific hour can also be a solution. This has already been planned by government. I hope it will start soon.
Similarity ODD-EVEN formula can also be applied in Kathmandu Valley. It was applied during blockade.
Polluted city like DELHI has already practiced it to reduce air pollution. They did it for 10-15 days which reduced the pollution by considerable amount.
This is not only the solution to pollution but a best solution of TRAFFIC JAM.

If we can make a short term plans on the basis of these three things, we can obviously reduce the amount of dust in roads.
To reduce air pollution, we need long term plans which includes proper urban design, afforestation, daily road maintenance and regulation of traffic.

THE ONLY POINT IS, LET'S MAKE SOME DISCUSSION TO BRING OUT THE SOLUTION INSTEAD OF RAISING THE PROBLEMS. PUTTING MASK ON THE FACE OF STATUES AND CONDUCTING MARATHON WILL NOT SOLVE THE PROBLEM. DISCUSSION SHOULD BE DONE IN LOCAL, POLITICAL AND NATIONAL LEVEL WITH MUCH PRIORITY.
"सरकार छदै छ नी भनेर बस्ने हो भने, न त यो समस्याको समाधान हुन्छ न त देश नै बन्छ !!!"

What do girls do when they are alone ?

WELCOME WELCOME WELCOME !!!

If you are a men, you must be in a great hurry to read it. If you are a girl, you must be expecting something different than what you do when you are alone.

In a recent survey carried by our team, we asked girls the same question:


"What do you do when you are alone ? "

The top five answer we received were:

1) READING
     READ, READ, READ !!! How much can they read  yar.... They read every part of their course book. They don't miss a single line and a single figure. Some girls also said, they read novels frequently. And the best medium of reading novels are mobile and computer. Some are offline while some are online. Buying a novel is rare because they love to share.

2) SLEEPING
    A girl said," I love to SLEEP". This must be a case when there is no intern-ate  or battery is dead.

3) WRITING
   Some girls are found to have great passion in writing. If you are wondering what they write with, its pencil and pen. Pencil for quality coz they can be erased and pen for satisfaction.

4) DANCING & SINGING
   Girls love to dance and sing.
   A shy girl said, "I dance to wildest when I am alone. I used to record them too."

5) TAKING PICTURES
    Taking selfie is common among every girls. They take lots and lots of selfie in different pose and positions.

Thank you for your patience.
If I have hurt your emotions, don't worry.

Smoking Benefits

"Every Cigarette you smoke reduces your expected life by 11 minute."
FUCK OFF !!! I have been listening this since I was a kid ...

कोइ गम भुलानेके लिए पी ते हे, कोइ चाए से तो कोहि दारु से पी ते हे, कोइ येसेही ले ते हे, कोइ joint भर भर के रात भर पी पी कर ढल्ते हे, हर लोक पी ते हे , हर रोज पी ते हे....
ये CIGARETTE हे भैया जी, नही पिया तो जिन्दगी क्या हे ........




Lets go straight into the benefits of smoking :

1) It is used by so many students believing that a cigarette helps them to concentrate in their study.
Actually it has been proved by an experiment carried by Wesnes and Warbuton where smokers and non smokers were required to watch a clock for 80 minute. Every time the hand of the clock paused. they had to press the button.
Not only did smokers outperform non-smokers, they were still performing just as well 60 minutes into the task and they had 10-15% faster reaction time.

2) Smoking reduces the aggression.
In an experiment where people were given to work 6 Hours without a pause. Non Smokers became angry, frustrated and aggressive while smokers were calm.

3) It is believed that smokers has good memory power.
(Don't know how long it exist)

4) It reduces the risk of breast cancer, knee replacement therapy...
(important one.. I don't know the biology inside it coz I am ENGINEER)

5) It lowers risk of DEATH after some heart attacks.
(after ...are you kidding me?? )

AND SMOKING IS PLEASURE......

NOTE: Take them seriously at your own risk.
