2. The process of diffusion is involved in transpiration of water vapours
3. The ions are absorbed by the simple diffusion during passive salt uptake
4. Diffusion is an effective means of transport of substances over a very short distance and helps in the translocation of food materials
Which of the following statements is/are with respect to rates in the building estimation? A) The rates for building estimation are usually taken from PWD schedule of rates, with appropriate escalation charges. B) Rates for different items in the estimate are the current rates for the completion of the items of work.
In industries titanium is hardened through diffusion of carbon. The concentration of carbon at 1mm into the surface of the titanium slab is 0.25kg/m3 and at 3mm the concentration is 0.68kg/m3. The rate at which the carbon is entering into its surface is 1.27*10-9kg/m2.s. calculate the value of diffusion coefficient of carbon.
Consider the relational schema given below, where eId of the relation dependent is a foreign key referring to empId of the relation employee. Assume that every employee has at least one associated dependent in the dependent relation. Employee (empId, empName, empAge) Dependent(depId, eId, depName, depAge) Consider the following relational algebra query: ΠempId(employee)-ΠempId (employee⋈(empId = eID)∧(empAge ≤ depAge)dependent) The above query evaluates to the set of empIds of employees whose age is greater than that of
Which of the following is correct with regarding the formation of Nitrogen? I. Nitrogen is obtained by liquefaction and fractional distillation of air. II. Nitrogen is obtained by reacting an aqueous solution of Ammonium chloride with Sodium Nitrite. III. Decomposition of Sodium or Barium Azide at high-temperature results in the formation of pure Nitrogen. IV Nitrogen is not soluble in water.
Solution of nitrogen in liquid iron may be assumed to follow Sievert's law. Nitrogen content of liquid iron. at 1873K in equilibrium with 1 atm pressure of nitrogen is measured as 0.044 (mass %). What will be the equilibrium nitrogen content in liquid iron (mass%), if nitrogen pressure is reduced to 0.25 atm?
In a gas mixture of hydrogen and oxygen, steady state equimolar counter diffusion is occurring at a total pressure of 100 kPa and temperature of 20°C. If the partial pressures of oxygen at two planes 0.01 m apart, and perpendicular to the direction of diffusion are 15 kPa and 5 kPa, respectively and the mass diffusion flux of oxygen in the mixture is 1.6 * 10–5 kmol/m2.sec, calculate the molecular diffusivity for the system. For equimolar counter current diffusion:

When acceptance of or information about an innovation spreads throughout the society (c) Expansion Diffusion  3. When expansion affects almost uniformly to all individuals and areas from a source region (d) Contagious Diffusion  4. Geographical transfer of culture traits by movements of people across space
Given below are four jumbled sentences. Select the option that gives their correct order. Interest rates, in turn, are a crucial determinant of how much firms and consumers want to spend. Conversely, a consumer may be lured into buying a new home if interest rates are low and mortgage payments are therefore more affordable. A firm faced with high-interest rates may decide to postpone building a new factory because the cost of borrowing is so high. The Federal Reserve System strongly influences the size and growth rate of the money stock, and thus the level of interest rates in the economy.
After GST and demonetisation, rising interest rates are set to hurt SMEs. Interest rates for loans against property (LAP) extended to small and medium sized enterprises (SMEs) are set to rise in the coming months of 2018 ‘ Rising interest rates, in addition to the muted operating environment for small businesses in India, will lead to an increase in delinquencies on LAP extended to SMEs’. The introduction of the goods and services tax (GST) in July 2017 and the government's demonetization policy have placed stress on the SME sector, which rising interest rates will exacerbate. Which of the following can be logically inferred from the statement above?
