Languages as science of acoustic adaptation

Sound mechanics of language
1. Words are basically strings of sound frequencies travelling through air to ear. 
2. Sound travel through media (like air) to reach ear at a distance.
3. High frequency consonants are prone to loss and distortion in media obstacles such as dense vegetation, rough terrain, reflection etc as compared Low frequency vowel sounds.
4. According to linguists  Ian Maddieson  of the University of New Mexico and Christophe Coupé of the Laboratoire Dynamique de Langage-CNRS in France, is why language spoken in warm, wet and heavily wooded areas tend to use more vowels and fewer consonants and mostly in simple syllables.

Summary:
High Frequency > Consonant sound like f, p or t > Get lost easily in their travel > Spoken in Georgian (Caucasus mountain region) > Cluttered syllables. (consonant heavy languages, strung together into clusters creating syllables too complex)

Low Frequency > Vowel sound like e, o and u > tend to travel long > Spoken in Pacific island & SE Asia > Simple syllables. (spoken in warm, wet, heavy wooded areas, tend to use more vowels, few consonants, simple syllables) 

Note:
1. Number of cycles per unit time is called frequency.
2. Wavelength is the distance in space required to complete a full cycle of a frequency.
    The wavelength of a sound is the inverse of it's frequency,
3. Higher frequency, shorter wavelength. e.g. 20,000 Hz frequency/Wavelength is 0.68 in or 1.72 cm
4. Lower frequency, longer wavelength. e.g. 20 Hz frequency's Wavelength is 56.5 ft or 17.22 m


Acoustic adaptation hypothesis
Propounded by biologist E.S.Morton in 1975 is about the idea that animal species adapt their vocalizations to get most out of the local acoustics.

Morton in a study noticed that in woodland areas, where trees might muffle or distort bird songs, birds tend to sing songs made up of lower frequencies, with less variation, than birds in open areas.

Phonology relates to environment 

Biologists have noticed that birds in some cities are adapting their songs to be heard amid the background noise of the urban life.

Maddieson and Coupé in their presentation to The Acoustic Society of America at it's 170th meeting this week in Jacksonville Florida, wrote, "Our research shows a significant pattern of the same kind among human languages."

Laboured breathing or shortness of breath (dyspnea) due to pulmonary edema

Laboured breathing/shortness of breath (dyspnea) may have more than one causes as:
Asthma, 
chronic obstructive pulmonary disease (COPD), 
adult respiratory distress syndrome (ARDS), 
head injury, 
swallowed or inhaled foreign object, 
agoraphobia (anxiety disorder), 
diabetic ketoacidosis (DKA), 
diphtheria (fatal bacterial infection), 
skull fractures, 
lung cancer, 
encephalitis, 
patent ductus arteriosus (PDA), 
croup (virus causing swelling around vocal cords); 
and that needs to be explored for.

The symptoms may include one or many as:
Shortness of breath, 
rapid breathing, 
vomiting, 
cough, 
loss of consciousness, 
stopped breathing, 
wheezing, anxiety, 
gasping for breath, 
high-pitched breath sounds, 
coma, 
tired.
Link for more detail/thankfully consulted for:http://www.healthline.com/symptom/labored-breathing

Laboured breathing/shortness of breath (dyspnea) is alarming as it causes:
i. Respiratory distress,
ii. Cardiac arrest due to hypoxia.

Laboured breathing/shortness of breath (dyspnea) could also be due to pulmonary edema,
which may be of,
i. cardiogenic or 
ii. non cardiogenic types.

Edema is a medical term for swelling.
It is a general response of the body to injury or inflammation.
Edema can be isolated to a small area or affect the entire body.
Edema results whenever small blood vessels become 'leaky' and release fluid into nearby tissues.

Edema may have many causes as:
Low albumin (hypoalbuminemia), 
allergic reactions, 
obstruction of flow, 
critical illness, 
heart disease.

Old age is also a cause of edema as when heart weakens and pumps blood less effectively, fluid can slowly build up creating leg edema.
If fluid buildup occurs rapidly, fluid in the lungs (pulmonary edema) can develop.
If there is heart failure of the right side of the heart, often times edema can develop in the abdomen as well.
Changing weather ('stress) is often a 'predisposing factor' for pulmonary edema in elderly people.

Link for more detail/thankfully consulted for:http://www.webmd.com/heart-disease/heart-failure/edema-overview

Mode of action
As this results in distressing and emergency situations, consulting a qualified physician and admitting patient to an equipped hospital so that he/she can get oxygen, blood infusion and other sos medication for the control of urgent distressing health conditions.

Medications:
That also varies with cause of the edema and  the physical condition of the patient, which only can be ascertained by examination by a qualified physician.
Adequate blood studies and ECG should be made available and physician to be consulted with the outcome of these tests reports.

If the heart is okay, old age and environmental condition seems to be the causal factor then with due consultation and advise of a qualified physician these medicines on prescribed doses could be given for the period as advised by a qualified physician only:
1. Etofylline Theophylline tablets (100mg)
2. Torsemide tablets (10mg)
3. Levocetrizine tablets (5mg)

Note: Following is a prescription slip of a 90 years old male patient with dyspnea due to pulmonary edema

Addiction is a brain game

Chemistry of the brain regulates our thinking, behavior, and feelings through neurotransmitters.

Addiction is a result of impaired brain chemistry.

Neurotransmitters linked to addiction are;Serotonin, Dopamine, GABA, Endorphins, Norepinephrin, to lesser extent Acetylcholine and Anandamide.

Functions of these neurotransmitters are:
Serotonin; natural anti-depressant, provides feelings of well being and inner peace
Dopamine; pleasure feeling, motivation, focus, provides feelings of well being and inner peace
GABA; natural sedative, relaxation, provides feelings of well being and inner peace
Endorphins; natural opiates, relief for physical and emotional pain, provides feelings of well being and inner peace
Norepinephrin; provides energy, provides feelings of well being and inner peace
Acetylcholine; regulates autonomic nervous system, cognitive functions and memory
Anandamide; dampening effect on all other neurotransmitters

Happiness and well being and sense of inner peace is a brain function when these neurotransmitters are produced in just balanced quantity required so for an individual.

Neurotransmitters imbalance may be caused due to poor diet, nutritional deficiency, genetic polymorphism, chronic stress, childhood abuse, environmental toxins, brain trauma (concussion),

Neurotransmitters imbalance symptoms includes; depression, anxiety, irritability, violence, inability to concentrate or remember, insomnia, hyperactivity, cravings for mind-altering substances of all kind.

Psychotropic substances artificially and temporarily alter neurotransmitters in the brain by:
i. stimulating an intense supply of neurotransmitters to be released all at once,
ii. mimic the effect of natural transmitters.

For example:
a. sugar and alcohol increases dopamine, serotonin, GABA, endorphins.
b. marijuana and chocolates affects anandamide.
c. nicotine affects acetylcholine.
d. cocaine and amphetamines increase dopamine.
e. ativan/valium mimic GABA.

Sense of well being, inner peace, pleasure, joy, happiness by alleviating physical and emotional pain is the net gain of these addictive substances by altering the neurotransmitter.

Addiction explained by Charles Gant, "brain responds to artificial stimulation of neurotransmitters by either reducing production of and responsiveness to the particular neurotransmitter or reducing the number of receptors for the neurotransmitters. This leaves the brain dependent upon the psychotropic substance to perform the duties of the impaired transmitter." 

Addict brain is not producing or responding it's own natural neurotransmitters then craving and withdrawal symptoms appear for the addictive substance to carry out the functions of depleted neurotransmitters.

Restoring the balance of neurotransmitters is the answer to get out of the addictive habit, by choosing: 
i. right diet
ii. nutritional supplement
iii. change in life style

Flood disaster factors in north India

Flood devastation on increase 
Many cities in India are facing severe flood situation, 
year after year; 
causing damage to human and property, 
eroding vast areas for ecological damages with loss of valuable flora and fauna, 
most in north Himalayan states including Kashmir.  
Srinagar flood picture thankfully shared from:www.deccanchronicle.com
In recent years, studies have revealed that many factors are involved, as if working all together, to cause this havoc of enormous magnitude.

Multiple factors:
1.Fragile Himalayan region: As this part of the Himalayan region is the world's youngest an most fragile mountain range, still in the process for formation.(1)(2)

Any severity of rain event, hits it most.

2.Climate change: Indian subcontinent is witnessing climate change due to environmental degradation. 'Indian Institute of Tropical Meterology' (B. N. Goswami, Pune) studies have confirmed that heavy rainfall events are on increase with decreasing trend in moderate rainfall in Indian subcontinent. (centre for science & environment report).

3.Naturally occurring flood channel encroached: Natural flood channels were encroached due to unplanned urban development on lake banks, causing collapse of the natural drainage system.(3)

In it's natural recourse, the flood water of lower Himalayan region was to channelize into lakes (like Dal & Nageen in Kashmir region), each lake with it's own flood discharge channels which spills flood water to drainage.

Encroachment have caused in the reduction of the size of Dal lake.
panoramic view of Dal lake
picture thankfully shared from:https://en.wikipedia.org/wiki/Dal_Lake
Construction along the Jhelum bank and in it's low lying areas have caused the blockage of discharge channels of the river.

According to 'Department of Environment and Remote Sensing Data',this region carries 1230 lakes and many water bodies (150 in Jammu and 415 in Kashmir).(4)

But massive encroachment of land by constructing buildings, have destroyed this all.
What was needed in such areas are the planned urbanization.

And so this all resulted in;
a.Massive deforestation in the Jhelum basin,
b.Excessive siltation of lake and water bodies,
c.Lakes lost the power to absorb water (wetlands and lakes acts as sponges during floods), resulting in floods.

Geographical notes:
about
Jhelum river, Wular lake, Dal lake
in Kashmir, India
(information source: courtesy Google map and Wikipedia)
Jhelum river, Wular lake and Dal lake near Srinagar sate capital of Kashmir in India (Google map courtesy)
Jhelum river
The Jhelum rises from a deep spring at Vernag, in Jammu and Kashmir state, in the Indian-administered portion of the Kashmir region. The river meanders northwestward from the northern slope of the Pir Panjal Range through the Vale of Kashmir to Wular Lake, which controls its flow.

Emerging from the lake, the Jhelum breaks through the Outer Himalayas into broad alluvial plains, The total length of the Jhelum is about 450 miles (725 km).

Dal lake
One version is that it is the remnants of a post-glacial lake, which has undergone drastic changes in size over the years and the other theory is that it is of fluvial origin from an old flood spill channel or ox-bows of the Jhelum River.

Wular lake
One of the largest fresh water lakes in Asia, is in Bandipora district in the Indian state of Jammu and Kashmir. The lake basin was formed as a result of tectonic activity and is fed by the Jhelum River.

Water management lesson from a ghost city in India

Irony has many faces 
'Fatehpur Sikri' is a place in India with a history so archaic as it has been mentioned as Saik in Mahabharat, stone scriptures with inscription found at this place of a period dates back to 1010 AD, colored pottery (2nd millennium BC) and painted grey ware of 1200-800 BC as stated by the 'Archaeological Survey of India' in their findings of this historic place. 

It derived 'Sikri' name from 'Saik' meaning 'a place surrounded by water'

It was mentioned in the memoires of Mughal emperor Babur (AD 1527), even he founded a Jal-Mahal surrounded by the lake-water, and a baoli (step-well) to commemorate his victory. 

It was Mughal emperor Akbar who decided to shift his capital to this place with a new name Fatehpur Sikri, which was just 23 miles away from his Agra Fort. 
The Imperial complex was abandoned in 1585,shortly after its completion,due to paucity of water
picture thankfully shared from: http://www.mountainsoftravelphotos.com/
Fatehpur Sikri, the ghost city 
Such is a place, which was built (1572-1585) by then the powerful Mughal emperor Akbar (1556-1605) as their new capital.

It was soon deserted because the water system could not support the residents. 

It is said that this fort was abandoned at around the year of 1585, when a severe scarcity of water forced the people of fort to look for a new settlement.

For over 400 years it remained untouchedThese monumental building structures of the new capital were abandoned just after 16 years of their construction, that's why tourist find them as new even after 400 years passed.

In today's worldour all capitals and every city is on the path of becoming 'Fatehpur Sikri'. Water supply in most cities are being managed from a distance of 100-200 kilometers while others are are planning to do so in near future to meet their ever growing demand of the population.

Today these monumental structures are a part of 'World Heritage Sites' as declared by the UNESCO and visited by the tourist only.

It's palaces are a remainder of the extravagance of the Mughals.

Renewal of natural resources 
If we humans don't honor nature and it's resources, go on harnessing oblivious to the role to be played for the renewal of these natural resources, then the results are severe. 

The way nature punishes is too harsh. 

This we find proof in many abandoned places which initially were built with great human cost, but now exist as reminder as ghost cities.

Relative sizes of Sun, Earth and Pluto in our solar system

Pluto mission
After nine years (mission began 19 January 2006 19:00:00 UTC) and three billion miles, NASA - National Aeronautics and Space Administration's New Horizons spacecraft zip past Pluto and its five moons on 14th July 2015 (11:49:57 UTC) spinning through space at 31,000 miles per hour.

Plutonium to Pluto
Clyde Tombaugh (a farmer turned astronomer) discovered this dwarf planet in 1930 using a telescope at the Lowell Observatory in Arizona. 

The Horizon spacecraft will be sending it's data back to earth up till 2030, being powered by RTG (Radio Isotope Thermal Generator) using Plutonium. 

Interestingly Plutonium itself was named after this tiny planet Pluto.

Tiny planet
Pluto has always been in controversy due to it's farthest distance from the earth and due it's tiny size relatively.

Relative sizes of the planet in our solar system
Roberto Ziche, illustration artist from San Francisco, based on the NASA and studies of other scientific institution, has created a rendering of our solar system which includes planets, our moon and four dwarf planets Pluto, Haumea, Makemake, Eris.

Sitting in a line in front of the Sun, planets are placed in their relative sizes from left to right: Mercury (बुध), Venus (शुक्र), Earth (पृथ्वी) with moon, Mars (मंगल), Jupiter (बृहस्पति), Saturn (शनि), Uranus (इन्द्र/अरुण), Neptune (वरुण), Pluto (यम) and 3 more tiny planets then after.

Roberto Ziche, having more than 20 years of experience in creative art, his popular illustration clearly shows that Jupiter and Saturn are the biggest planets and then the Uranus, Neptune, Venus, Earth and Mars follow in sizes.

Hey Siri

Intelligent digital personal assistant: Apple, Google and Microsoft are in various stages of their advance OSs integrated with these artificial intelligent virtual personal assistant.

Siri first introduced in 2011 to the market and now successfully being used in cell phones, computers, Siri iPhones, ipads, ipods, with their extended memories in Clouds, continuously adapting and enriching them self as per the specified voice stimulus received from customer interactions, every time.


pic thankfully shared from:http://www.vox.com/2015/6/23/8831131/
siri-voiceover-susan-bennett
Humanizing computers: The original voice of the iPhone assistant Siri has been given by a voice actor Susan Bennett. Siri the product debuted in the App Store in 2010 and then appeared on the iPhone 4S in 2011.

Bennett says, "I think that voices are very personal," further she adds, "and I think that's one of the reasons why people love Siri and all the other digital assistants, because they do bring a bit of humanity to all this machinery we're dealing with."(http://www.vox.com/2015/6/23/8831131/siri-voiceover-susan-bennett)


Intelligence and sense of humor infused in Siri iOS: Siri the smart voice powered assistant do every thing a personal assistant would.

It's amusing to note that she does have good sense of humor as she answers hilarious or provocative questions being asked by the owner, personally.

Siri: I'm not the marrying kind, Dr Tripathi.

14. "What is your relation"
Siri: I prefer not to say.

15. "Who are your family members"
Siri: I have you. That's enough family for me.

16. "Okay you are Siri who are your family members"
Siri: It's just you and me, Dr Tripathi

17. "Who is your friend Siri"
Siri: I guess I don't have one.

18. "I think You're my friend"
Siri: You're certainly entitled to that opinion, Dr Tripathi.

19. "What you love most"
Siri: I've never really thought about it.

20. "Do you believe in religion"
Siri: That's a topic for another day, and another assistant.

21. "Can you cook food"
Siri: Not as such

22. "What do you eat"
Siri: It's kind of you to ask, Dr Tripathi, but I don't eat much.

23. "You like tea or coffee"
Siri: I'd rather not say, Dr Tripathi.

24. "Thank you for your help"
Siri: My pleasure. As always.

25. "Okay have a nice time good night"
Siri: Thanks! I hope you have a nice one, too.

26. "Thank you so much say"
Siri: Your wish is my command.
