How to cure dry eyes

2023-09-02T02:17:00.003+05:30

Dry Eyes is a problem due to which the eyes do not get proper tears for lubrication which is a mixture of water + fatty acids + salt + mucus. Its a complex gel which keeps the eyes hydrated and lubricated for proper functioning.

Not having proper tears is common nowadays due to more screen time as the person does not blink the eyes.

Not blinking the eyes leads to the jamming of the tear ducts in our eye lids which blocks the flow of tear gel into our eyes.

I'm a patient of dry eyes for the past 15 years and it went on deteriorating over time. Nothing helped me in curing the dry eyes. Doctors only suggested for artificial tears(Carboxymethyl cellulose sodium) which relieved the eye pain for sometime but it did not help in curing the dry eyes in anyway.

The only way I could cure my dry eyes was with homeopathic medicines. It took around 4 months time to cure and during that time I did not do any screen time (1 minute max at a time).

Take these medicines for atleast 3-4 months time before which there would be NO results.
Homeopathic medicines are always safe without any side effects.
If you want you can consult any homeopathic doctor for suggestions.

The medicines that are to be taken orally -

nux moschata 200C - 2 drops directly on tongue - 2times daily

Belladonna 30C - 4 drops in 1/4 cup of water - 4 times daily

alumina 30C - 4 drops in 1/4 cup of water - 4 times daily(atleast after 3 hours gap)

calcarea fluorica 6x - 4 tablets (not to be chewed but to be kept in mouth to dissolve with saliva) - 4 times daily

natrum mur 6x - 4 tablets (not to be chewed but to be kept in mouth to dissolve with saliva) - 4 times daily

argentum nitricum 200C - 2 drops in 1/4 cup of water - 2 times daily

sanicula europaea 200C - 2 drops in 1/4 cup of water - 2 times daily.

sulphur 30C - 4 drops in 1/4 cup of water - 4 times daily

euphrasia offcinallis 30C - 4 drops in 1/4 cup of water - 4 times daily

ferrum phos 6x - 4 tablets (not to be chewed but to be kept in mouth to dissolve with saliva) - 4 times daily

Arsenic Album 30C - 4 drops in 1/4 cup of water - 1 time daily in or around mornings

Senega Q(mother tincture) - 15 drops in 1/4 cup of water - 3 times daily

you can also take the below medicines for faster revival but as such not much required

bryonia 200 - 2 drops directly in mouth or 1/4 cup of water - 2 times daily

opium 200C - 2 drops directly in mouth or 1/4 cup of water - 2 times daily

Also a rich source for Vitamin A is required which you can get in multivitamin tablets from any pharmacy (see for amount of vitmain A in the box)

Rich source of Omega 3 fatty acids are required which you can also get from any pharmacy with Omega 3 tablets or you can get from mustard oil. The pure mustard oil have a pungent smell.

Rich source for Sulphur is required which you can get from lemons.

Also use Cineria Maritima (without alcohol) eye drops but not at the time of pain in the eyes. Use it when you do not have pain in the eyes. During pain in the eyes use the artificial tears which you normally use

Euphrasia offcinallis is to be taken orally which helps reducing pain in the eyes. Use it more often(every 1 hour) if you have pain in the eyes.

Belladonna can also be frequented every 2 hours during pain in the eyes or Belladonna 200C can be used.

Hope this helps and please comment below...

natural and easy way to cure duodenitis

2016-06-24T14:42:00.003+05:30

How to get rid of duodenitis?

I was suffering from duodenitis for 9 years. My body had turned into a living corpse and after taking meals I had long sessions of gastric problems specifically burping.

There are no allopathic medicines for duodenitis. I used homeopathic medicine and they cured my duodenitis upto 95%. The homeopathic medicines are -

antimonium crudum 30C

natrum phos 6x or 30C

lycopodium 30C

Kali Bichrome 30C

Graphites 200C

Carbo Veg 30C

uranium nitricum 30C

sulphur 20C

Phosphorus 30C

Baptisia Tinctoria -Mother Tincture

Hydrastis Canadensis -Mother Tincture

Also simply workout more. It is 10 minutes of cardio and more of weight training for 30-60 mins in a day.

I started doing cardio and weight training at the Gym. It was very difficult for my so very weak body to do weight training but i could manage it slowly within 1-2 weeks of normal exercises. This solved my gastric problems upto 95% and now I am following doing workouts every day in and out.

Thanks for reading and do try it out regularly for atleast 1 month. I suggest please join any Gym or workout and weight training instructor.

Please share your ideas and experiences in the comments.

glassfish reload redeploy application without admin console

2014-09-13T00:38:00.001+05:30

Glassfish can reload or redeploy the application already deployed.

You dont have to go to the admin console to do that.

If your application is running from locally available files just paste a file named ".reload"(empty file name with reload extension) with the WEB-INF directory or usually where the index file is and that's it. Glassfish will redeploy your application.

The contents of the file ".reload" may be empty or atleast I have kept it empty. When you again you have to redeploy your web application just re-upload or run command "touch .reload" in unix and Glassfish will redeploy your web application.

Basically Glassfish just sees the timestamp of the .reload file against the application's last reloaded time. If the timestamp of the .reload file is greater then Glassfish will reload your application.

Apache - how to change the document root directory

2014-02-27T01:35:00.000+05:30

Apache - how to change the document root directory

https://help.ubuntu.com/community/ApacheMySQLPHP

Apache2 has the concept of sites, which are separate configuration files that Apache2 will read. These are available in /etc/apache2/sites-available. By default, there is one site available called 000-default. This is what you will see when you browse to http://localhost orhttp://127.0.0.1. You can have many different site configurations available, and activate only those that you need.

As an example, we want the default site to be /home/user/public_html/. To do this, we must create a new site and then enable it in Apache2.

To create a new site:

Copy the default website as a starting point. sudo cp /etc/apache2/sites-available/000-default.conf /etc/apache2/sites-available/mysite.conf
Edit the new configuration file in a text editor "sudo nano" on the command line or "gksudo gedit", for example:gksudo gedit /etc/apache2/sites-available/mysite.conf
Change the DocumentRoot to point to the new location. For example, /home/user/public_html/
Change the Directory directive, replace to
You can also set separate logs for each site. To do this, change the ErrorLog and CustomLog directives. This is optional, but handy if you have many sites
Save the file

Now, we must deactivate the old site, and activate our new one. Ubuntu provides two small utilities that take care of this: a2ensite (apache2enable site) and a2dissite (apache2disable site).

$ sudo a2dissite default && sudo a2ensite mysite

Finally, we restart Apache2:

$ sudo /etc/init.d/apache2 restart

If you have not created /home/user/public_html/, you will receive an warning message

To test the new site, create a file in /home/user/public_html/:

$ echo 'Hello! It is working!' > /home/user/public_html/index.html

Finally, browse to http://localhost/

Java Collections Interview Questions

2010-01-12T23:20:00.000+05:30

What is the Collections API?

The Collections API is a set of classes and interfaces that support operations on collections of objects.
Example of classes: HashSet, HashMap, ArrayList, LinkedList, TreeSet and TreeMap.
Example of interfaces: Collection, Set, List and Map.

What is the List interface?

The List interface provides support for ordered collections of objects.

How can we access elements of a collection?

We can access the elements of a collection using the following ways:
1.Every collection object has get(index) method to get the element of the object. This method will return Object.
2.Collection provide Enumeration or Iterator object so that we can get the objects of a collection one by one.

What is the Set interface?

The Set interface provides methods for accessing the elements of a finite mathematical set. Sets do not allow duplicate elements.

What’s the difference between a queue and a stack?

Stack is a data structure that is based on last-in-first-out rule (LIFO), while queues are based on First-in-first-out (FIFO) rule.

What is the Map interface?

The Map interface is used associate keys with values.

What is the Properties class?

The properties class is a subclass of Hashtable that can be read from or written to a stream. It also provides the capability to specify a set of default values to be used.

Which implementation of the List interface provides for the fastest insertion of a new element into the middle of the list?

a. Vector
b. ArrayList
c. LinkedList
d. None of the above

ArrayList and Vector both use an array to store the elements of the list. When an element is inserted into the middle of the list the elements that follow the insertion point must be shifted to make room for the new element. The LinkedList is implemented using a doubly linked list; an insertion requires only the updating of the links at the point of insertion. Therefore, the LinkedList allows for fast insertions and deletions.

How can we use hashset in collection interface?

This class implements the set interface, backed by a hash table (actually a HashMap instance). It makes no guarantees as to the iteration order of the set; in particular, it does not guarantee that the order will remain constant over time. This class permits the Null element.

This class offers constant time performance for the basic operations (add, remove, contains and size), assuming the hash function disperses the elements properly among the buckets.

What are differences between Enumeration, ArrayList, Hashtable and Collections and Collection?

Enumeration: It is series of elements. It can be use to enumerate through the elements of a vector, keys or values of a hashtable. You can not remove elements from Enumeration.

ArrayList: It is re-sizable array implementation. Belongs to 'List' group in collection. It permits all elements, including null. It is not thread -safe.

Hashtable: It maps key to value. You can use non-null value for key or value. It is part of group Map in collection.

Collections: It implements Polymorphic algorithms which operate on collections.

Collection: It is the root interface in the collection hierarchy.

What is difference between array & arraylist?

An ArrayList is resizable, where as, an array is not. ArrayList is a part of the Collection Framework. We can store any type of objects, and we can deal with only objects. It is growable. Array is collection of similar data items. We can have array of primitives or objects. It is of fixed size. We can have multi dimensional arrays.

Array: can store primitive ArrayList: Stores object only

Array: fix size ArrayList: resizable

Array: can have multi dimensional

Array: lang ArrayList: Collection framework

Can you limit the initial capacity of vector in java?

Yes you can limit the initial capacity. We can construct an empty vector with specified initial capacity

public vector(int initialcapacity)

What method should the key class of Hashmap override?

The methods to override are equals() and hashCode().

What is the difference between Enumeration and Iterator?

The functionality of Enumeration interface is duplicated by the Iterator interface. Iterator has a remove() method while Enumeration doesn't. Enumeration acts as Read-only interface, because it has the methods only to traverse and fetch the objects, where as using Iterator we can manipulate the objects also like adding and removing the objects.

So Enumeration is used when ever we want to make Collection objects as Read-only.

What is HashMap and Map?

Map is Interface and Hashmap is class that implements this interface.

What is the significance of ListIterator?

Or

What is the difference b/w Iterator and ListIterator?

Iterator : Enables you to cycle through a collection in the forward direction only, for obtaining or removing elements

ListIterator : It extends Iterator, allow bidirectional traversal of list and the modification of elements

Difference between HashMap and HashTable? Can we make hashmap synchronized?

1. The HashMap class is roughly equivalent to Hashtable, except that it is unsynchronized and permits nulls. (HashMap allows null values as key and value whereas Hashtable doesn’t allow nulls).
2. HashMap does not guarantee that the order of the map will remain constant over time.
3. HashMap is non synchronized whereas Hashtable is synchronized.
4. Iterator in the HashMap is fail-safe while the enumerator for the Hashtable isn't.

Note on Some Important Terms
1)Synchronized means only one thread can modify a hash table at one point of time. Basically, it means that any thread before performing an update on a hashtable will have to acquire a lock on the object while others will wait for lock to be released.

2)Fail-safe is relevant from the context of iterators. If an iterator has been created on a collection object and some other thread tries to modify the collection object "structurally”, a concurrent modification exception will be thrown. It is possible for other threads though to invoke "set" method since it doesn’t modify the collection "structurally”. However, if prior to calling "set", the collection has been modified structurally, "IllegalArgumentException" will be thrown.

HashMap can be synchronized by

Map m = Collections.synchronizeMap(hashMap);

What is the difference between set and list?

A Set stores elements in an unordered way and does not contain duplicate elements, whereas a list stores elements in an ordered way but may contain duplicate elements.

Difference between Vector and ArrayList? What is the Vector class?

Vector is synchronized whereas ArrayList is not. The Vector class provides the capability to implement a growable array of objects. ArrayList and Vector class both implement the List interface. Both classes are implemented using dynamically resizable arrays, providing fast random access and fast traversal. In vector the data is retrieved using the elementAt() method while in ArrayList, it is done using the get() method. ArrayList has no default size while vector has a default size of 10. when you want programs to run in multithreading environment then use concept of vector because it is synchronized. But ArrayList is not synchronized so, avoid use of it in a multithreading environment.

What is an Iterator interface? Is Iterator a Class or Interface? What is its use?

The Iterator is an interface, used to traverse through the elements of a Collection. It is not advisable to modify the collection itself while traversing an Iterator.

java resultset using mysql stored procedure

2008-11-29T20:42:00.004+05:30

Obtaining a java sql resultset using mysql stored procedure is quite a headache....

any better implementation is always a welcome....

I have used "MySQL Connector/J" jdbc driver available here

I have used java.sql.CallableStatement in the java class.

The Table in mysql is: -
-----------------------------------------------------------------------
DROP TABLE IF EXISTS `test_post`;
CREATE TABLE `test_post` (
`Post_Id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`Subject` varchar(50) NOT NULL,
`Post_msg` text NOT NULL,
PRIMARY KEY (`Post_Id`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8;
-----------------------------------------------------------------------

The stored procedure is: -
-----------------------------------------------------------------------
CREATE DEFINER=`root`@`localhost` PROCEDURE `sp_select_test_post`(in id integer)
BEGIN
SELECT * FROM test_post where post_id=id;
END
-----------------------------------------------------------------------

The java code: -
-----------------------------------------------------------------------
public class Main {

/**
* @param args the command line arguments
*/
public static void main(String[] args) {
// TODO code application logic here
//System.out.print();
try
{
Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/void?" + "user=myUsername&password=myPassword");
CallableStatement stmt = conn.prepareCall(" call sp_select_test_post(?) ");
stmt.setInt(1, 2);
stmt.execute();
ResultSet rs = stmt.getResultSet();
/*ResultSetMetaData rmeta = rs.getMetaData();
System.out.print(rmeta.getColumnCount());*/
while(rs.next()) {
System.out.print(rs.getString(2) + "\n");
}
System.out.print("connected");
conn.close();
}
catch (ClassNotFoundException cnfe) {
System.out.print(cnfe);
}
catch(InstantiationException ie) {
System.out.print(ie);
}
catch(IllegalAccessException iae) {
System.out.print(iae);
}
catch(SQLException sqle) {
System.out.print(sqle);
}
}
}
-----------------------------------------------------------------------

Hope that runs in your systems too... Good Luck..
Please post any better implementation ... thanks...
