This document contains the resume of Abdul Nisar Bhutta, including his personal details, academic and professional qualifications, computer skills, 10+ years of experience as a mechanical draftsman and AutoCAD designer for various companies in Pakistan and UAE. His responsibilities included executing drawings for piping, HVAC, steel structures, and MEP systems. Major projects listed include refineries, power plants, hotels, and industrial facilities. He is currently a senior AutoCAD designer at Descon Engineering in Lahore.
1. The document discusses entropy and the Clausius inequality which is a consequence of the second law of thermodynamics. It involves heat transfer (Q) to or from a system, absolute temperature (T) at the boundary, and a cyclic integral.
2. For a reversible heat engine or refrigeration cycle, the cyclic integral of Q/T is equal to zero, but it is always less than or greater than zero for irreversible cycles depending on whether it is a heat engine or refrigeration cycle.
3. Entropy change is calculated as the area under the T-S curve for a reversible process, but is always greater for an irreversible process between the same two states. Property diagrams like T-
The document discusses the second law of thermodynamics. It states that heat always flows spontaneously from hotter to colder bodies and not vice versa. This is because processes proceed in a certain direction and not the reverse direction. The second law is needed to determine the direction of spontaneous processes since the first law does not restrict direction. Two common statements of the second law are then presented: 1) It is impossible for a heat engine to receive heat from a single reservoir and produce work without rejecting some heat. 2) It is impossible to transfer heat from a cold to a hot body without external work. Examples of heat engines, refrigerators, and heat pumps are provided to illustrate these principles.
If you also want to immigrate to Australia, then, the time has never been better to apply for the General Skilled Migration Programs including Skilled Independent Visa (Subclass 189), Skilled Nominated (Subclass 190) Visa and Skilled Nominated or Sponsored (Provisional) (Subclass489) Visa.

1. The document derives three equations relating the entropy change of ideal gases undergoing isentropic (reversible adiabatic) processes.
2. For an ideal gas with constant specific heats, the isentropic relationships are: Tv^k = constant, Tp^k = constant, and Pv^k = constant, where k is the heat capacity ratio Cp/Cv.
3. These isentropic relationships allow the calculation of changes in temperature, pressure, and specific volume of an ideal gas during isentropic compression or expansion processes based on its initial state properties.
The document discusses reversible and irreversible processes. It defines a reversible process as one that can reverse itself without leaving any trace on the system or surroundings. Reversible processes are idealizations that do not actually occur in nature but can approximate real processes. The Carnot cycle, composed of reversible processes, represents the most efficient heat engine possible between two temperature limits. The Carnot cycle consists of four steps: two isothermal expansion/compression processes and two adiabatic expansion/compression processes. The efficiency of a Carnot engine depends only on the temperatures of the hot and cold reservoirs. Reversible processes set the theoretical maximum efficiency and minimum work consumption that real irreversible engines can approach but not meet.
Markedsføring på nett og mobil – hva må man tenke på?
Sosiale medier, søkemotorer og mobile applikasjoner forandrer hverdagen til forbrukerne. Dette frokostseminaret handlet om hvordan man kan lykkes som markedsfører i et stadig mer fragmentert medielandskap.
Foredragsholdere var Marianne Otterdahl Møller og Anders Gulbrandsen fra Making Waves.
Kort foredrag om hvordan forså og bruke sosiale medier som kommunikasjonskanal for effektiv forretningsdrift. Forklarer gjennom caser og eksempler hvordan drive:
Kundeservice og produktutvikling
Hvordan få gode ambassadører
Hvordan nå rett målgruppe
Betydningen av masse
Hvordan drive brannslukking
Grunnleggende kurs i sosiale medier holdt for gründere og andre små og mellomstore næringsdrivende, i regi av www.nesoddparken.no
Dette kurset er del 1, og det vil komme kurs del 2 i februar / mars 2013.
Foredrag holdt for Norsk Senter for Fremmedkulturell Verdiskapning i Drammen, med fokus på hvordan sosiale medier kan hjelpe små- og mellomstore bedrifter med å skape muligheter for økt salg, godt omdømme og god kundebehandling.
Hva skal til for å gjennomføre en kampanje i sosiale medier? Her er forslag til sommerkampanje for en liten bedrift. Presentasjonen er utarbeidet i forbindelse med nettstudier i faget Sosiale medier og WEB 2.0 ved itfag/HiST våren 2015.

2. Dette er prosjekt Barnas restaurant
• Sertifisering/godkjenning
av barnevennlige spisesteder
• Gratis for bedriftene
• Først i Norge – antakelig!
• Kvadraturen blir pilot
• Mulig utvidelse til hele
Kristiansand og Knutepunkt
3. Slik skal Barnas restaurant være synlig
• Konkret bevis på
godkjenning som barnevennlig
• Egen nettside med
restaurantoversikt
• Aktiv bruk av Facebook
• Forhåpentlig medieomtale,
lokalt og nasjonalt
5. What’s in it for me?
Markedsføringen i prosjekt Barnas restaurant skal:
• Øke besøket fra målgruppen
• Øke restaurantenes bevissthet
• Være service til barnefamilier som vil spise i Kristiansand
• Øke kjennskap til barnevennlige restauranter
• Styrke posisjonen til Kristiansand som Barnas By
6. Dette trenger vi deres hjelp til
• Lage sjekkliste med kriterier (workshop)
• Lage synlig bevis på godkjenning (ws)
• Fylle ut skjema med info, bilder osv.
