SAMSUNG GALAXY NOTE 5 CASES

noreply@blogger.com (abhilash) — Tue, 04 Aug 2015 09:02:00 +0000

If you are a tech person and would go browse over the internet you will see the never ending leaked specifications, renders and cases for the Samsung Galaxy Note 5. This Phone is one of the most searched topic on the internet. Such a hit and it is not even launched.

This upcoming device from the digital world giant is believed to share the same design concept as the Galaxy S6 and the Galaxy S6 Edge. Also according to the latest news and rumours the Galaxy Note 5 will have a metal chasis which will be very durable.

This particular handset is expected to feature tapered edges on the rear along both the sides of the device. This feature of the design is a replica of the Galaxy S6 Edge design. Having this kind of a design, the tapered edges results to a non-existent grip of the phone making it vulnerable to slip off the hand and obviously falling to the ground.

Even though this phone might have a metal chasis it might withstand a fall or 2. This metal body would crack too after a few falls which is bound to happen if the design stays the same (as per the rumours, nothing is official yet).

You would probably require a good phone case for the phone for it to be safe and working. You are putting in a lot of money to get this handset so obviously you would want to keep it safe. There are plenty of cases which Samsung provides for its handsets. Finding cases for Samsung is the easiest. It is easier than finding cases for any other phone.

There is a wide range for the phone cases starting real cheap rising up a great deal. Fancy glam cases are also mostly available for Samsung smartphones and probably would be available for this too.

Human Resource Management Skill

noreply@blogger.com (abhilash) — Wed, 27 Feb 2013 09:14:00 +0000

Human Resource is the backbone of any organization. They are the moving ambassadors of the company as well as the reason for the company to produce better results at a competitive sphere. So, it can undoubtedly be considered that success of the organization to a large extent depend on the skill and abilities of the employees and the quality of the output they produce. The human resource department is particularly involved in this concern with the intention to recruit talented staffs for company benefits. All these make human resource one of the most demanding subject areas for the students of MBA. The course aimed in making the students a manager who can control the employees and take care of their requirements.

Human resource management guides the students to master the skill of handling manpower through practical and theoretical knowledge. It covers a number of tasks which include searching eligible candidates, fixing dates for interviews, knowing the skills they have, checking the background and gathering other such information, implementing welfare policies for the employees, counseling employees on their career, etc. Resource development is another task of a HR which monitors the work and progress of a worker. It includes special training,assessment and even studying performance for providing appraisal, promotion and other such amenities.Sorting the salaries of the employees, tracking the leave applications, giving bonuses, etc. are also the tasks of HR.

Analytical and quantitative skills are some of the other key requirements of HR. They should have a hold over communication and have an ability to make the employees understand processes and procedures in an organization. They should even know the norms of local and federal legislation. Even HR must have the skill to translate the numerical data into comprehensible English. The MBA colleges in Kolkata and elsewhere put an emphasis on these aspects because without these qualities, a HR cannot deal or communicate with the employees coming from different background.

Whether it is about the business environment or working procedures, HR needs to have an eye on everything and competency level should be excellent. They must ensure that workers would be provided with safety at work and every other requirement at office shall be maintained. With rising number of businesses, the necessity of human resource management skill is increasing day by day.

Being a service based economy the value of HR is in high demand. Therefore, managing the resources of business comes as the first priority. They need to chalk out strategies for easy functioning that can satisfy the workers. In other words, it can even be stated that HR has the responsibility to maintain integrity and stability in the working environment.

Unquestionably, this is a challenging task where the HR department balances between the organizational goal as well as the needs of the workers. They have to make choices while implementing strategies that are beneficial for the organization and at the same time provide the workers the opportunities that they deserve.

History of cricket

noreply@blogger.com (abhilash) — Fri, 28 Aug 2009 19:38:00 +0000

एक नए शोध में दावा किया गया है कि क्रिकेट मूल रूप से ब्रिटेन का खेल नहीं है बल्कि उत्तर बेल्जियम के अप्रवासियों के जरिए इंग्लैंड लाया गया है। एक कविता जिसके बारे में कहा जाता है कि यह 1533
में लिखी गई थी, उसकी खोज से ये बात सामने आई है कि ये खेल फ्लैंडर्स में शुरू हुआ था।

ऑस्ट्रेलियन नैशनल यूनिवर्सिटी के पॉल काम्पलेक्स के अनुसार जॉन स्केलटन की रचनाओं में फ्लेमी बुनकरों को 'किंग ऑफ क्रिकेटर्स' कहा गया है। इस खोज ने पुराने तथ्य को चुनौती दी है जिसके अनुसार ये मान लिया गया था कि क्रिकेट का खेल अंग्रेज बच्चों के खेलकूद से निकला है। इंग्लैंड में इसका पहला निश्चित उल्लेख 16वीं शताब्दी में मिलता है जब चर्च से भाग कर खेलने वालों पर जुर्माना लगाया गया था।

इस देश में जनसाधारण के इस खेल को पब्लिक स्कूल, ऑक्सफर्ड और कैम्ब्रिज जैसी यूनिवर्सिटियों में अगली शताब्दी में शामिल कर लिया गया। पहले क्रिकेट क्लब की स्थापना हैम्बेलडन में 1760 में हुई और सुप्रसिद्ध मेरिलेबॉन क्रिकेट क्लब (एमसीसी)की स्थापना 1787 में हुई।

लेकिन जर्मन शोधकर्ता और उनके ऑस्ट्रेलियाई सहयोगी कैम्पबेल ने कहा है कि इस खोज से ये साबित होता है कि कुछ भी हो यह विशिष्ट ब्रितानी खेल ब्रितानी नहीं है। कैम्पबेल ने 16वीं शताब्दी की एक रचना 'द दमेज ऑफ इपोक्रिसी' में क्रिकेट का एक उल्लेख ढूंढ निकाला है। इस रचना को अंग्रेजी के कवि स्केलटन से जोड़ा जाता है और इसमें फ्लेमी बुनकरों का जिक्र मिलता है जो दक्षिण-पूर्वी इंग्लैंड में जा बसे थे। उन्हें 'किंग ऑफ क्रिकेट' यानी क्रिकेट का बादशाह कहा गया है। इसमें विकेट का भी जिक्र है। आपको यह सोच कर हैरानी होगी कि बेल्जियम क्रिकेट नहीं खेलता है।

hi dear friends welcome once again
now a days i am little bit busy due to my upcoming semester examination
the even semester examination of WBUT will be start form first week of JUNE due to which i am busy ,All of you know how hard syllabus for engineering course . it like impossible to complete the whole syllabus in 6 months.
Teachers and students both are active just before examination,( before one month of exam). teaches give assignment and practical work just before examination. Every day write 20-30 pages of assignment ,lab copy ,after that if you able to menages time go through your big and boring course book, which so weighted if any one hit you by that book properly you do not able to work for some day.
this is time of examination for all engineering college and universities ,so i talk about study pattern of this universities, i the student come here after completing their 12th ,with some dream ,all the principle which read upto class 12th ,is try to apply in real life with the help of lab.they though this is a place where they show their creativity and do some thing different but due to bad educational police of Indian government this is not happen.
Engineering is a course in which the main focus of study is practical knowledge . but Indian government want to student become clerk rather than engineer . there is a need to change the pattern of educational system .
What you think about it and what kind of changes you want in educational system of India . say your idea .
I am waiting for your valuable comment on this impotent topic because this is matter of India development
