हेल्लो दोस्तों! काफी अरसे के बाद आप सबका स्वागत है. असल में पलायन कर गया था कुछ दिनों के लिए क्यूंकि पढाई में ज्यादा समय देना पढ़ रहा था. फिलहाल इस समय तो गर्मी की छुट्टी हो गयी है तो क्यूँ न कुछ नया किया जाये. तो मई अपने कुछ अच्छे और बहुत कुछ बकवास विचार से आप लोगों को परेशान करने आ गया हूँ. सोच रहा हूँ की कुछ नया करूँ ताकि कुछ नया सोचने को मिल जाये. तो शयद मई अपने सपने से कुछ नया ले कर आऊं. तो आज का विषय है मेरा 4 Semester में जिंदगी. क्या बताऊँ मैं तो लाइफ का सुस्त घोड़ा हो गया. सोना सोना और खूब सोना.. हे हे हे... तो मैंने निश्चय किया था की इस साल मई करूँगा पढ़ाई करूँगा. पर जिंदगी ने ऐसा मद दिखया की मैं भटक गया किस किस रस्ते जाऊँ. so I confuse with rasta where I gotta go.. confusin with place to place and then OMG.... :( :'(

Why in my pen drive the folder change into its shortcut?

Hey Guys!! I want to share something!!




Many times You face this problem!! You insert your pendrive in computer and You see that your all important folders convert into shortcut form!! You are unable to see ur matters!! Then what to do?? U format it?? No No....



First you take out ur matters from your pen drive!! But how search the matter??? No No..



Just follow these easy steps..



1.Click on "Start" -->Run-->type cmd and click on OK.

2.Here I assume your pendrive as G:

3.Enter this command.

4.attrib -h -r -s /s /d g:\*.*

5.Note : Replace the letter g with your flash drive letter.

Now check for your files in Pen Drive.



You will see that your all shortcut formed folder get back in normal condition!! But still the shortcut copy present with its original folder name!! No problem.. Just delete these crap folder!!!



OK Ok!!!!



Thank You!! Like if it works!! Mera to theek ho gya!! Ab aap bhi aazma lijiye!!

Textures

1. HOLOCRYSTALLINE TEXTURE


The term holocrystalline is used when a rock is composed entirely of crystals. This type of texture is characteristic of deep seated or plutonic igneous rock, e.g. GRANITE

2. HEMICRYSTALINE TEXTURE

The term hemicrystalline is used when a rock is composed partly of crystals and partly of glass. This is characteristic of rock which has consolidated on or near the surface e.g. Volcanic rocks.

3. HOLOHYALLINE TEXTURE

The term holohyalline is used when a rock consists wholly of glass. This type of texture is restricted to volcanic and hypabyssal rock occurring at the immediate contact which the country rock, e.g. Obsidian.

4. ALLOTRIOMORPHIC TEXTURE

This is holocrystalline equigranular texture in which the minerals are of approximately same size and majority of the crystal are anhedral in shape, e.g. Aplite.

5. HYPIDIOMORPHIC TEXTURE

This is a type of holocrystalline, equigranular texture in which the minerals are approximately same size and majority of the minerals are sub-hedral e.g. Granite.

6. PANIDIOMORPHIC TEXTURE

This is a type of holocrystalline, equigranular texture in which the minerals are of approximately same size and majority of crystals are euhedral in shape, e.g. Lamprophyre.

7. PORPHYRITIC TEXTURE

This is a type of inequigranular texture (which is characterized by marked difference in grain size of minerals) in which larger crystals, known as phenocrysts, are embedded in a fine – grained ground mass, e.g. Basalt, Andesite, and Rhyolite.

8. FELSOPHYRIC TEXTURE

This is a variety of in-equigranular, porphyritic texture in which larger crystals, known as phenocrysts are embedded in a cryptocrystalline ground mass.

9. VITROPHYRIC TEXTURE

This is variety of inequigranular porphyritic texture in which larger crystals known as phenocrysts are embedded in a glassy ground mass e.g. Basalt.

10. POIKILITIC TEXTURE

This is a type of holocrystalline inequigranular (marked difference in grain size) texture and the term implying the occurrence of number of oriented or un-oriented crystals, totally enclosed within a large crystal.

11. OPHITIC TEXTURE

This is a special case of poikilitic texture in which plates of Augite enclose numerous thin laths of plagioclase. This is the characteristic texture of the rock known as Dolerite.

12. SUB-OPHITIC TEXTURE

This texture is similar to ophitic but in this case fine laths of plagioclase are partially enclosed in Augite crystal.

13. CLASTIC TEXTURE

Clastic texture results from the accumulation of detrital particles. It is characterized by point contents between (grains) and associated intergranular spaces.

14. NON-CLASTIC TEXTURE

Non-Clastic texture are dominated by the crystalline texture results from the crystallization within or at the surface of sediments and are characterized by an interlocking crystal mosaic.

15. SCHISTOSE TEXTURE

The texture is characterized by Prismatic content acicular minerals. Quartz usually is associated with these minerals. All the above minerals show a parallel array among each. Rock other showing schistose texture is called schist.

16. GNEISSOS TEXTURE

This texture is characterized by distinct bandings of light (quartz, feldspars, muscovite etc.) and dark (hornblende, biotite, hypersthenes, garnet) colour minerals. In addition to compositional banding it may contain streaks, lines of quartz and / or plagioclase. Rock exhibiting gneissose texture is called gneiss.

17. GRANULOSE TEXTURE

The texture is characterized by predominance of equidimentional minerals such as Quartz, Feldspar, Pyroxene and Calcite etc.

Masti Start!!!!

हे शैतान मित्रों!! कैसे हो? मई तो यहाँ BHU में पास हो गया और फिर से मस्ती के मूड में आ रहा हूँ!!! I got passed with BACK BERRY!! Dekho bahi maine thodi thodi padhai bhi chaaloo kar di hai , to dua karo ki mai paas ho jaun is baar with no berry ke saath.

Life for no thing!!!

Hey I am here in BHU these time with my sisters for their entrance exam. But what about myself I have been here starving for good marks since last year and still there is no reason found for my good marks. What should I do for it... I am still karing Bakwaas for my future and aiming for nothing.. In these summer I had planned to do many things but still I have not thouched my books yet I am BACK HOLDER.

I want to do somthing good for my career but I am perplexed to do what?? I am still in dileema and trying to do. But theses are only my thinking. Ya extra thinking is problem for me. But I am stiill Thinking. This makes me unhappy and hopeless. I am unable to find my reight way. When I am happy? I am always thinking about this. Perhaps when success comes to my way. I am Day Dreamer. And this is the main problem. Sapne to bahut dekhte hain hum, Sapne to bahut dekhte hain hum, Per in sapno me jaan dalne ka aukaad hume na mili abhi tak!!!!

Ya my condition at this time is like this!!!! :(

कुछ मज़ा कुछ सज़ा!!!

हेय दोस्तों कैसे हो? मैं तो नचता टपता मजे कर रिया हूँ. वैसे ये गर्मी की छुट्टी में मैंने बहुत कुछ करने की सोची है पर कितना कर पाता हूँ नहीं पता. पर कुछ तो करना है!!!

चलो आज मै अपने ब्लॉग पर आप लोगों के लिए अगले सेमेस्टर का सेलेबस खास तौर पर PMG लोगों के लिए है!!
