changes in atmospheric temperature and lowering in water-table (WT) are expected to affect peatland nutrient dynamics. To understand the response of peatland nitrogen (N) and phosphorus (P) dynamics to warming and drainage in a continental wooded-bog of hummock-hollow microtopography, we compared three sites: (a) control, (b) recently drained (2-3years;experimental), and (c) older drained (12-13years;drained), during 2013. The WT was lowered at experimental and drained sites to 74 and 120cm, respectively, whereas a warming of similar to 1 degrees c was created at one half of the microforms using open-top chambers. Responses of peat total inorganic nitrogen (TIN=nitrate nitrogen [NO3--N]+ammonium nitrogen [NH4+-N]) and phosphate-P (PO43--P) pools and vegetation c:N ratio, c-13 and N-15 to the experimental treatments were investigated across sites/microforms and over time. Peat TIN available and extractable pools increased with deepening of WT and over time and were greater at hummocks relative to hollows. In contrast, the PO4 pools increased with short-term drainage but reverted to very close to their original (control) nutrient values in the longer term. The WT and warming driven change in the peat TIN pool was strongly reflected in the vascular vegetation c:N ratio and shrub c-13 and N-15, whereas moss nutrient dynamics did not vary between sites. Therefore, we suggest that atmospheric warming combined with WT deepening can increase availability of mineral N and P, which then can be reflected in vascular vegetation and hence modify the productivity and ecosystem functioning of the northern midlatitude continental wooded bogs in the long term.

Book Description
Mastering Arduino is an all-in-one guide to getting the most out of your Arduino. This practical, no-nonsense guide teaches you all of the electronics and programming skills that you need to create advanced Arduino projects. This book is packed full of real-world projects for you to practice on, bringing all of the knowledge in the book together and giving you the skills to build your own robot from the examples in this book. The final two chapters discuss wireless technologies and how they can be used in your projects.
The book begins with the basics of electronics, making sure that you understand components, circuits, and prototyping before moving on. It then performs the same function for code, getting you into the Arduino IDE and showing you how to connect the Arduino to a computer and run simple projects on your Arduino.
Once the basics are out of the way, the next 10 chapters of the book focus on small projects centered around particular components, such as LcD displays, stepper motors, or voice synthesizers. Each of these chapters will get you familiar with the technology involved, how to build with it, how to program it, and how it can be used in your own projects.
What you will learn
• Explains the basics of electronics and circuits along with the Arduino IDE and basicc operations
• Use sensors to build a mini weather station
• control LEDs using code
• Power a robot arm using stepper motors
• Remotely control your Arduino using RF, Bluetooth LE, and Bluetooth classic
• Make a sound tone generator with buttons

Two new compounds 1-(4-tert-butyl-benzenesulfonyl)-4-[5-(4-methoxy-phenyl)-[1,3,4]oxadiazol-2-yl]-piperazine ( I ) and 1-[5-(4-methoxyphenyl)-[1,3,4]oxadiazol-2-yl]-4-[(4- bromo ) benzene sulfonyl ]-piperazine ( II ) of 1-[5-(4-methoxy-phenyl)-[1,3,4]oxadiazol-2-yl]- piperazine derivatives have been synthesized and the structures were confirmed by single crystal X-ray diffraction studies. The computational density functional theory (DFT) calculations have been carried out to shed light on reactive sites for electrophilic and nucleophilic nature of the molecules. Both the compounds were crystallized in the monocliniccrystal system, in P 2 1 /n space group wherein the piperazine ring in both the structures adopts a chair conformation. Both the compounds I and II exhibit intermolecular hydrogen bonds of the type c—H…O and contribute to the crystal packing. Further, the molecular Hirshfeld surface analysis was carried out which reveals the nature of intermolecular contacts, the fingerprint plot provides the information about the percentage contribution and revealed that the H…H (54.7% for compound I and 40.2% for compound II ) interactions has the major contribution.

Liver fibrosis is the center of diagnosis and management of essentially all chronic liver diseases. While liver biopsy examination still has a role in diagnosis and drug development, it is replaced by non-invasive assessments of liver biopsy in majority of the clinical scenarios. Radiological approaches, namely transient elastography, acoustic radiation force impulse imaging, shear wave elastography, magnetic resonance elastography provide accurate diagnosis of advanced fibrosis and cirrhosis. Serum test formulae based on common laboratory parameters or more specialized parameters including those commercially available panels FibroTest?, FibroMeter? and Enhanced Liver Fibrosis are also available. combining different modalities may further improve the accuracy. The role of all these non-invasive assessments has been further expanded from diagnostic to prognostic, e.g. risk prediction of hepatocellular carcinoma (Hcc) by LSM-Hcc score. Treatment of liver fibrosis can be achieved by controlling the underlying diseases, with chronic viral hepatitis as the most established disease model. currently there are multiple clinical trials evaluating different treatment options to improve fibrosis in patients with non-alcoholic fatty liver disease. Specific anti-fibrotic treatment targets e.g. direct downregulation of hepatic stellate cell, collagen synthesis inhibitors and transforming growth factor-βantagonists have been tested in laboratory and pending further studies in clinical settings.
