01;what is hot spots? 02;what is bumbing? 03;methods for determine efficiency of outoclave |
|
Answer» spot is a specific LOCATION that provides Internet access via a wireless local area network (WLAN). The term is generally synonymous with a Wi-Fi connection. A network that creates a HOTSPOT primarily includes a modem and wireless router. The radio frequency (RF) WAVES sent by the wireless network extend in different directions from its centralized location. These signals become weaker as they travel, either further from the central location or due to interference. Hotspots provide convenience to millions of Internet users, but they are rife with security ISSUES. For example, free public hotspots are often the target of hackers and identity thieves. The attackers create rogue or fake hotspots that look identical to legitimate hotspots. If users unknowingly connect to these rogue access points and use their sensitive data for LOGIN or a similar purpose, the attackers can then easily retrieve the sensitive data using different techniques. 2.Bumping is a phenomenon in chemistry where homogenous liquids boiled in a test tube or other container will superheat and, upon nucleation, rapid boiling will expel the liquid from the container. In extreme cases, the container may be broken. 3.I don't know about this. sørry |

What is reproduction? Explain in details. |
|
Answer» ction (or procreation or breeding) is the biological process by which new individual organisms – "offspring" – are produced from their "parents". Reproduction is a fundamental feature of all known life; each individual ORGANISM exists as the result of reproduction. There are two forms of reproduction: asexual and sexual.In asexual reproduction, an organism can reproduce without the involvement of another organism. Asexual reproduction is not limited to single-celled organisms. The cloning of an organism is a form of asexual reproduction. By asexual reproduction, an organism creates a genetically similar or identical copy of itself. The evolution of sexual reproduction is a MAJOR puzzle for biologists. The two-fold cost of sexual reproduction is that only 50% of organisms reproduce[1] and organisms only pass on 50% of their genes.Sexual reproduction typically requires the sexual interaction of two specialized organisms, called gametes, which contain half the number of chromosomes of normal cells and are created by meiosis, with typically a male fertilizing a female of the same species to create a fertilized zygote. This produces offspring organisms whose genetic characteristics are derived from those of the two parental organisms. |

Empirical research in Pakistan in particular creates so many problems for the researchers”. State the problems that are usually faced by such researchers. |
|
Answer» s faced by Researchers during Research √The Problems faced by Researchersin India, particularly those engaged in empirical research, are facing several problems.Some of the important problems are as follows: The lack of a scientific training in the methodology of research is a GREAT impediment for researchers in our country. There is paucity of competent researchers. Many researcher stake a leap in the dark without knowing research methods. Most of the work, which goes in the name of research is not methodologically sound. Research to many researchers and even to their guides, is mostly a scissor and paste job without any insight shed on the collated materials. The consequence is obvious, vi., the research results, quite often, do not reflect the reality or realities. Thus, a systematic study of research methodology is an urgent necessity. Before undertaking research projects, researchers should be well equipped with all the methodological aspects. As such, efforts should be made to provide shortcutting courses for meeting this requirement. There is insufficient interaction between the university research departments on one sideband business establishments, government departments and research institutions on the other side. A great deal of primary data of non-confidential nature remain untouched/untreated by the researchers for want of proper contacts. Efforts should be made to develop satisfactory liaison among all concerned for better and realistic researches. There is need for developing some mechanisms of a university—industry interaction programmer so that academics can get ideas from practitioners on what needs to be researched and practitioners can apply the research done by the academics. Most of the business units in our country do not have the confidence that the material supplied by them to researchers will not be misused and as such they are often reluctant in SUPPLYING the needed information to researchers. The concept of secrecy seems to be sacrosanct to business ORGANIZATIONS in the country so much so that it proves an impermeable barrier to researchers. Thus, there is the need for generating the confidence that the information/data obtained from a business unit will not be misused. Research studies overlapping one another are undertaken quite often for want of adequate information. This results in duplication and fritters away resources. This problem can be solved by proper compilation and revision, at regular intervals, of a list of subjects on which and the places where the research is going on. Due attention should be given toward identification of research problems in various disciplines of applied science which are of immediate concern to the industries. There does not exist a code of conduct for researchers and inter-university and interdepartmental rivalries are also quite common. Hence, there is need for developing a code of conduct for researchers which, if adhered sincerely, can win over this problem. Many researchers in our country also face the difficulty of adequate and timely secretarial assistance, including computer assistance. This causes unnecessary delays in the completion of research studies. All POSSIBLE efforts be made in this direction so that efficient secretarial assistance is made available to researchers and that too well in time. University Grants Commission must play a DYNAMIC role in solving this difficulty. Library management and functioning is not satisfactory at many places and much of the time and energy of researchers are spent in tracing out the books, journals, reports, etc.,rather than in tracing out relevant material from them. There is also the problem that many of our libraries are not able to get copies of old and new Acts/Rules, reports and other government publications in time. This problem is felt more in libraries which are away in places from Delhi and/or the state capitals. Thus,efforts should be made for the regular and speedy supply of all governmental publications to reach our libraries. There is also the difficulty of timely availability of published data from various government and other agencies doing this job in our country. Researcher also faces the problem on account of the fact that the published data vary quite significantly because of differences in coverage by the concerning agencies. There may, at times, take place the problem of conceptualization and also problems relating to the process of data collection and related things |

How to make hydrogen gas in Hindi |

Answer» ाला में जस्ते पर तनु गंधक अम्ल की क्रिया से यह प्राप्त होता है। युद्ध के कामों के लिए कई सरल विधियों से यह प्राप्त हो सकता है। 'सिलिकोल' विधि में सिलिकन या फेरो सिलिकन पर सोडियम हाइड्राक्साइड की क्रिया से, 'हाइड्रोलिथ' विधि में कैलसियम हाइड्राइड पर जल की क्रिया से 'हाइड्रिक' विधि में एलुमिनियम पर सोडियम हाइड्राक्साइड की क्रिया से प्राप्त होता है। गर्म स्पंजी लोहे पर भाप की क्रिया से एक समय बड़ी मात्रा में हाइड्रोजन तैयार होता था।आज हाइड्रोजन प्राप्त करने की सबसे सस्ती विधि 'जल गैस' है। जल गैस में हाइड्रोजन और कार्बन मनॉक्साइड विशेष रूप से रहते हैं। जल गैस को ठंडाकर द्रव में परिणत करते हैं। द्रव का फिर प्रभाजक आसवन करते हैं। इससे कार्बन मनॉक्साइड (क्वथनांक 191 सें.) और नाइट्रोजन (क्वथनांक 195 सें.) पहले निकल जाते हैं और हाइड्रोजन (क्वथनांक 250 से.) शेष रह जाता है।जल के वैद्युत अघटन से भी पर्याप्त शुद्ध हाइड्रोजन प्राप्त हो सकता है। एक किलोवाट घंटा से लगभग 7 घन फुट हाइड्रोजन प्राप्त हो सकता है। कुछ विद्युत् अपघटनी निर्माण में जैसे नमक से दाहक सोडा के निर्माण में, उपोत्पाद के रूप में बड़ी मात्रा में हाइड्रोजन प्राप्त होता है। |

Explain in detail why farmers have to add fertiliser to ensure good crop yields year after year. Name and include minerals required by a plant, describe what the plant needs these minerals for and what could happen if a plant did not get enough minerals. Use scientific words (6 Marks) |
|
Answer» nutrients in our food originally come from the soil. In order to create HEALTHY crops full of nutrients, farmers need to work with healthy soil. ... Farmers turn to fertilizers because these substances contain plant nutrients such as nitrogen, phosphorus, and potassium.Fertilisers provide mineral ions NEEDED for healthy growth in PLANTS. As plants grow, they absorb mineral ions from the WATER in the soil through their root HAIR cells . Over time, the concentration of these ions decreases, so farmers and gardeners add fertilisers to the soil. |

Describe the principal of electric motor with a figure and write its use |
|
Answer» RE√PRINCIPAL OF WORKING OF A DC MOTOR↓↓A motor is an electrical machine which converts electrical energy into mechanical energy. The principle of working of a DC motor is that "whenever a current carrying conductor is placed in a magnetic field, it experiences a mechanical force". The direction of this force is GIVEN by Fleming's left hand rule and it's magnitude is given by F = BIL. Where, B = magnetic flux density, I = current and L = length of the conductor within the magnetic field. flemings left hand rule: If we stretch the first finger, second finger and THUMB of our left hand to be perpendicular to each other AND direction of magnetic field is represented by the first finger, direction of the current is represented by second finger then the thumb represents the direction of the force experienced by the current carrying conductor. WORKING OF A DC MOTOR When armature windings are connected to a DC supply, current sets up in the winding. Magnetic field may be provided by field winding (electromacnetism) or by using permanent magnets. In this case, current carrying armature conductors experience force due to the magnetic field, ACCORDING to the principle stated above. Commutator is made segmented to achieve unidirectional torque OTHERWISE, the direction of force would have reversed every time when the direction of movement of conductor is reversed the magnetic field. |
