In the wild, boas hide and ambush passing prey. Due to a sluggish metabolism, boas can go months without eating. Despite their large size, Boa constrictors have comparatively small appetites. The boa first strikes at the prey, grabbing it with its teeth it then proceeds to constrict the prey until death before consuming it whole.MacBook Pro 13.3" Retina, MacBook Air 13" Retina, MacBook Air 13.3"(2020, M1): 2560x1600 Dual monitor: The Boa constrictor is a big snake, but it is actually much smaller than fellow constrictors (boids), such as the Burmese python. However, they do hunt, particularly in regions with a low concentration of suitable prey, and hunting generally occurs at night. They live in a range of habitats, but prefer humid rainforest conditions. Boa constrictors are ambush predators, so often lie in wait for an appropriate prey to come along, when they attack. Boa constrictors are large snakes that are found in the wild in South and Central America and Mexico. It makes their eyes appear milky, blue, or opaque so that the snake cannot see very well, causing it to be more defensive than it might be otherwise. You probably love those places My favorite place is the rainforest. Like all snakes, Boa constrictors in a shed cycle are more unpredictable, because of the substance that lubricates between the old skin and the new one. Wow They are both terrestrial, which means they live on ground, and arboreal, which means they also live in trees. Their body markings consist of beige blotches on a dark brown background. Their bite can be painful, especially from large snakes, but is rarely dangerous to humans. Description The boa constrictor is a large, heavy-bodied snake. These snakes strike when they perceive a threat. Boa constrictors often occupy the burrows of medium-sized mammals, where they can hide from potential predators. As semi-arboreal snakes, young Boa constrictors may climb into trees and shrubs to forage however, they become mostly terrestrial as they become older and heavier. They are nocturnal, but they may bask during the day when night-time temperatures are too low. Boa constrictors generally live on their own and do not interact with any other snakes unless they want to mate.

I gave the top of my head a 7 once because I just wasn't paying attention. Have a friend check to make sure you didn't miss anything, and always double check you're putting the right number guide on. Sides I do even or a bit longer than the top section of the back, and hold the clippers bare at an angle to taper it around the ears. The top I do an 11 or 12 right in front and a 10 or 11 over the rest. Make sure you "roll" the clippers up to finish between each section, that way the 4 fades evenly to a 5 which fades evenly to a 6. Sometimes I do it a bit longer - the best part of having clippers is you can keep it just the length you like, rather than getting it super short just to lengthen the time before your next haircut. From the bottom, near the neckline, gets a 4, an inch or so above that a 5, and then starting right about level with the top my ears gets a 6 up to the top. The numbers on the guards on mine represent 8ths of an inch:įor my hair, I divide the back of my head into three areas. If all you want to do is buzz it down to half an inch, it couldn't be easier.įor those who want a simple non-buzz cut, this is what I do. Not just saving money, but being able to groom myself any time is priceless. I stopped going to a barber about ten years ago and it was life-changing. (People sometimes ask if I'm in the military, but I never have been.) It works well for my receding hairline. I ended up going guardless on the back/sides, then blending into a #2 on top, a cut I refer to as "mil-spec". You literally can feel one hair though if you're careful enough. As others have mentioned, you can feel the ones in back with your hand, but you have to go slow and feel very carefully. Look in different lights/angles to make sure you don't have any stragglers.Brush everything: the wall, light switch, the clippers, cord, behind your ears, your shoulders, backs of your hands, etc. Get a little hand brush to help clean up.Please do this instead of tossing the clippers and buying a new one. If the blade is oiled and ever feels like it's just not cutting well (or worse, pulling hair), then it's time to have the blade sharpened.Might make your head smell like a clean gun for an hour, but whatever. Run it for a second and then turn it off, dab off any excess oil.

An energy-efficient Superframe for wireless sensor communication network employing directional mm-wave wireless access technologies is proposed for systems that require very high throughput, such as high definition video signals, for sensing, processing, transmitting, and actuating functions. This paper presents an energy-efficient Medium Access Control ( MAC) protocol for very-high-throughput millimeter-wave (mm-wave) wireless sensor communication networks (VHT-MSCNs) based on hybrid multiple access techniques of frequency division multiplexing access (FDMA) and time division multiplexing access (TDMA). Jian, Wei Estevez, Claudio Chowdhury, Arshad Jia, Zhensheng Wang, Jianxin Yu, Jianguo Chang, Gee-Kung (author)Ī hybrid MAC protocol design for energy-efficient very-high-throughput millimeter wave, wireless sensor communication networks From the analysis of contention based MAC protocols in term of energy consumption, it was being observed that protocols based on preamble sampling consume lesser energy than protocols based on static or dynamic sleep schedule. It was analyzed that contention based MAC protocols are less energy efficient as compared to hybrid MAC protocols. A comparison with respect to energy reservation scheme, idle listening avoidance, latency, fairness, data synchronization, and throughput maximization has been presented. This study also aims to give reader a better understanding of the concepts, processes and flow of information used in these MAC protocols for WSN. The goal of this comparative study is to provide a basis for MAC protocols and to highlight different mechanisms used with respect to parameters for the evaluation of energy and transmission efficiency in WSN. These nine protocols are classified in contention based and hybrid (combination of contention and schedule based) MAC protocols. In this paper, nine MAC protocols which includes S- MAC, T- MAC, Wise- MAC, Mu- MAC, Z- MAC, A- MAC, D- MAC, B- MAC and B- MAC+ for WSN have been explored, studied and analyzed. There are number of MAC protocols that exist in the literature proposed for WSN. The design of a MAC protocol should also address the issues of energy efficiency and transmission efficiency. The MAC protocols are responsible to communicate and coordinate between nodes according to the defined standards in WSN (Wireless Sensor Networks). International Nuclear Information System (INIS)ĭata communication between nodes is carried out under Medium Access Control ( MAC) protocol which is defined at data link layer. Mac protocols for wireless sensor network (wsn): a comparative study In addition, the analytical results of the MAC protocol are verified through an OPNET simulation. The performance of the proposed MAC protocol is evaluated through a numerical analysis using a Markov model. In order to address the deaf, hidden, and exposed node problems, we define RTS/CTS for the neighbor (RTSN/CTSN and Neighbor Information (NIP packets. Therefore, we propose a MAC protocol that exploits the characteristics of a directional antenna and can also work efficiently with omnidirectional nodes in a hybrid network. The MAC protocols that have been designed for use in homogeneous networks are not suitable for use in a hybrid network due to deaf, hidden, and exposed nodes. Thus, we require a novel MAC protocol for use with an intermediate wireless network that consists of heterogeneous sensor nodes equipped with either an omnidirectional antenna or a directional antenna. Efficient MAC Protocol for Hybrid Wireless Network with Heterogeneous Sensor Nodesĭirectory of Open Access Journals (Sweden)įull Text Available Although several Directional Medium Access Control (DMAC protocols have been designed for use with homogeneous networks, it can take a substantial amount of time to change sensor nodes that are equipped with an omnidirectional antenna for sensor nodes with a directional antenna. |
