  Human Values- Concept and Importance Human values are the core values that make up our personality and define how we act in life. These values are very important as they make up who we are and are what guide us through life. The values that we hold determine who we want to be as well as how we live our lives and the decisions that we make on an everyday basis. Without these values, our lives would become chaotic and there would be no meaning behind any of the things that we do or say. All humans have these values in some way or another, and it is up to us to choose which values we hold most dear. The 20th century philosopher Martha Nussbaum puts forth a list of ten innate human values: truth, beauty, justice, courage, temperance, wisdom, love, equality, modesty and hope. These are values that all humans should try to uphold as they go through their day-to-day lives. It is also important for society at large to recognize these values and make them explicit in social systems, insti...

‘Makers, step up your game.’ That’s the promise, or command, that Arduino makes about its new high-level board, the Arduino GIGA R1 WiFi.   It will,  says Arduino , pack advanced features into an accessible component, with the same form factor as the Mega and Due. Think of it as having two brains. One to deal with application specifics, perhaps, and the other to deal with general comms and status. The ST Microcontroller ( STM32H747XI ) is a dual core 32-bit MCU, bringing tother a Cortex-M7 at 480 MHz and a Cortex-M4 at 240 MHz. Wi-Fi or Bluetooth wireless comms are supported by a  Murata 1DX . In terms of pins, there are 76 Digital I/O pins, 12 Analog inputs, 2 DAC (DAC0/DAC1), 12 PWM pins, and also VRT & OFF. “Spring-boarding off the R&D efforts that power Arduino Pro products like Portenta H7, we have developed a product offering all the power of the STM32H7 microcontroller in the same form factor as the Mega and Due boards, at an accessible price point,” writes...

  Android is an open source and Linux-based   Operating System   for mobile devices such as smartphones and tablet computers. Android was developed by the   Open Handset Alliance , led by Google, and other companies. Android offers a unified approach to application development for mobile devices which means developers need only develop for Android, and their applications should be able to run on different devices powered by Android. The first beta version of the Android Software Development Kit (SDK) was released by Google in 2007 where as the first commercial version, Android 1.0, was released in September 2008. On June 27, 2012, at the Google I/O conference, Google announced the next Android version, 4.1  Jelly Bean . Jelly Bean is an incremental update, with the primary aim of improving the user interface, both in terms of functionality and performance. The source code for Android is available under free and open source software licenses. Google publishes mos...

  New technologies in lighting have today’s designers focusing a keen eye toward power quality. Power quality is the ability of an electrical system to deliver power in the safest and most efficient manner. Power quality is an important consideration in all industries, but with the advent of LEDs, Compact Fluorescent Lighting (CFL), High Intensity Discharge (HID) lighting and others, the commitment to an efficient power distribution system is more essential than ever. Many new lighting technologies, while certainly more efficient, can adversely affect power systems through harmonics which decrease power quality. Inefficiencies in power quality may limit the amount of devices that can be placed on the distribution network. It may also cause equipment to under-perform or to behave erratically. In the most severe cases, it can even harm the system and the devices along the network. Poor power quality management inevitably leads to an increase in operational costs and places an unneces...

  OCEAN  THERMAL ENERGY CONVERSION Abstract : Non-conventional sources are turning out to be significant sources of energy for humanity. With global warming a certainty, it is imperative that we turn to non-polluting and renewable sources of energy. One such source of energy is Ocean Thermal Energy Conversion (OTEC). Ocean Thermal Energy Conversion (OTEC) is a process that can produce electricity by using the temperature difference between deep cold ocean water and warm tropical surface waters. OTEC plants pump large quantities of deep cold seawater and surface seawater to run a power cycle and produce electricity. OTEC is firm power (24/7), a clean energy source, environmentally sustainable and capable of providing massive levels of energy. Introduction : Ocean thermal energy conversion (OTEC) is process that can produce electricity by using the temperature difference between deep cold ocean water and warm topical surface water. OTEC is an energy technology that converts sola...

  Biotech Revolution What Is 3D Bioprinting?  3D bioprinting is an additive manufacturing process where organic and biological materials such as living cells and nutrients are combined to create artificial structures that imitate natural human tissues. In other words, bioprinting is a type of 3D printing that can potentially produce anything from bone tissue and blood vessels to living tissues for various medical applications, including tissue engineering and drug testing and development. Perhaps the most significant driver of 3D bioprinting is regenerative medicine. According to Chris Mason and Peter Dunnill, this involves replacing or regenerating “human cells, tissue, or organs, to restore or establish normal function.” Here, bioprinting can have a central role, especially considering the high demand for organ and tissue transplants worldwide. In this article, we’ll explore the fascinating and futuristic technology known as 3D bioprinting. We’ll cover its most important asp...
