Hydrophilic polymeric networks that are capable of imbibing huge volumes of water and undergoing swelling and shrinkage suitably to facilitate controlled drug-release are called hydrogels. Their porosity and compatibility with aqueous environments make them highly attractive bio-compatible drug delivery vehicles. Hence, statement 1 is correct. The idea of cooling using hydrogels is simple: a heat sink is coated with 0.5-1-millimeter-thick hydrogel layer. Used commonly in laptops and CPUs, heat sinks are metallic structures with fins and ridges to increase their surface area for more efficient heat transfer. The hydrogel coating absorbs moisture from the air and swells up when a processor is not running full tilt. During peak hours, when the processor heats up, the water evaporates and cools the electronics.Hence, statement 2 is correct. Hydrogels have received extensive attention as functional lubricants because of their excellent anti-friction and anti-wear properties, tunable tribological performances, and effectiveness in alleviating lubrication failures caused by the creeping or leakage of conventional liquid lubricants owing to their semi-solid nature.Hence, statement 3 is correct.

None of the aircraft listed—Rafale, MiG-29, and Tejas MK-1—are considered fifth-generation fighter aircraft. Explanation: 1. Rafale – It is a 4.5-generation multirole fighter aircraft developed by Dassault Aviation (France). It incorporates advanced avionics, stealth features, and supercruise capability but lacks full stealth technology, which is a key characteristic of fifth-generation fighters. 2. MiG-29 – It is a fourth-generation fighter aircraft developed by Russia. It lacks stealth technology, sensor fusion, and advanced avionics seen in fifth-generation jets. 3. Tejas MK-1 – It is an indigenously developed fourth-generation fighter by India (HAL). While it has modern avionics and composite materials, it does not possess the stealth and sensor fusion capabilities of fifth-generation fighters. Conclusion: Since none of the listed aircraft meet the criteria for fifth-generation fighters (such as stealth, advanced sensor fusion, and AI-assisted avionics), the correct answer is: 0 (None of the above).

In which of the following are hydrogels used? 1. Controlled drug delivery in patients 2. Mobile air-conditioning systems 3. Preparation of industrial lubricants Select the correct answer using the code given below:

Consider the following aircraft: 1. Rafael 2. MiG-29 3. Tejas MK-1 How many of the above are considered fifth-generation fighter aircraft?

Let's break down the problem step by step: • There are 75% skilled workers, so 25% are unskilled. • Among skilled workers, 80% are permanent, so 20% are temporary. • Among unskilled workers, 20% are permanent, so 80% are temporary. Now, let's calculate the number of temporary workers: • For skilled workers, 20% are temporary, which is (20/100) * (75% of the total workers) = (1/5) * (75/100) * Total workers = (3/20) * Total workers. • For unskilled workers, 80% are temporary, which is (80/100) * (25% of the total workers) = (4/5) * (25/100) * Total workers = (1/5) * Total workers. So, the total number of temporary workers is (3/20 + 1/5) * Total workers = (15/100 + 20/100) * Total workers = (35/100) * Total workers = (7/20) * Total workers. Now, we know that the number of temporary workers is 126, so we can set up the equation: (7/20) * Total workers = 126 To solve for Total workers, multiply both sides by (20/7): Total workers = (126 * 20) / 7 Total workers = 360 So, the number of total workers in the company is 360. Therefore, the answer is (b) 360.
