There is a huge diff erence between electricity production and its demand. In order to meet the requirements, a selective power cut is carried out which is currently based on area and time. Although this is a simplistic solution, it has many drawbacks such as the area gets completely deprived of even the very basic appliances such as lights and fans, which do not contribute signifi cantly to the power consumption. This creates a need to come up with a solution so that no one gets deprived of using basic appliances at any time and still be able to reduce power consumption to fulfi ll the ever-growing demand. This work has dealt with the same by implementing a device selective protocol which can selectively cut power of particular devices depending on their energy rating, power rating, manufacturer etc. by the use of power line carrier communication. Hence, revolutionizing the whole concept of area selective power cut to device selective power cut. Since, IoT refers to a network of devices or “Things”, this work incorporates the basic principles of IoT by essentially creating a network of devices which can communicate with each other, over low bandwidth.

Large-amplitude ion acoustic solitons (IASs) in an ultra-relativistic degenerate quantum plasma consisting of non-degenerate warm light nuclei, stationary heavy nuclei and relativistically degenerate electrons are investigated. The Sagdeev’s pseudopotential approach is adopted to obtain the energy integral equation for the study large-amplitude IASs. The Mach number domain (M l ≤ M ≤ M h) is determined numerically in term of various parameters. Our numerical investigation shows that only compressive solitary waves can propagate in present plasma systems. The effect of different plasma parameters, such as the number density ( μe ), degenerate electron density ( k ), relativistic factor ( γ ), temperature ratio ( σ ) and Mach number ( M ), on the characteristic properties of solitary waves are reported. The corresponding phase trajectory is also drawn for the existing domain. The present theoretical study recovers the results from a previously published article (Sultana and Schlickeiser, Phys. Plasmas 25: 022110, 2018) for a cold multi-ion quantum plasma. Our result may be helpful to understand the basic characteristic of nonlinear solitary waves propagating in a quantum plasma, in which the non-degenerate warm light nuclei, stationary heavy ions and relativistic degenerate electrons are present. Plasmas with the given composition are found in astrophysical object such as white dwarfs, neutrons stars, etc.

Study Design: This was a prospective, randomized, controlled trial comprising 60 patients undergoing lumbosacral spine (noninstrumentation/ nonfusion) surgery. Purpose: The purpose of this study was to evaluate the efficacy of 0.2% ropivacaine (20 mL) administered alone as a single, preoperative, caudal epidural block injection versus that of intravenous analgesics in providing effective postoperative analgesia to patients undergoing lumbosacral spine surgery. Overview of Literature: Various studies have shown the effectiveness of a caudal epidural injection (bupivacaine or ropivacaine) in providing postoperative analgesia in combination with steroids or other analgesics. This study uniquely analyzed the efficacy of a single injection of caudal epidural ropivacaine in providing postoperative pain relief. Methods: Sixty patients who were scheduled to undergo surgery for degenerative lumbar spine disease (noninstrumentation/nonfusion) were consecutively divided into two groups, group R (Study) and group I (Control). 30 group R patients received a caudal epidural block with 20 mL of 0.2% ropivacaine after the administration of general anesthesia. 30 group I patients received no preoperative analgesia. Intravenous analgesics were administered during the postoperative period after a complaint of pain. Various parameters indicating analgesic effect were recorded. Results: There was a significant delay in the average time to the first demand for rescue analgesia in the study group, suggesting significantly better postoperative pain relief than that in the control group. In comparison with the control group, the study group also showed earlier ambulation with minimal adverse effects. The requirement for intraoperative fentanyl was higher in the control group than that in the study group. Conclusions: Preemptive analgesia with a single epidural injection of ropivacaine is a safe, simple, and effective approach, providing better postoperative pain relief, facilitating early mobilization, and decreasing the intraoperative requirement for opioid administration.

The cause of recurrent miscarriage (RM) remains unexplained in approximately 30% to 50% cases. The association of inherited thrombotic factors and RM patients has not been documented from the northern part of India. A total of 40 patients had been investigated for inherited thrombophilia workup (protein C, protein S [PS], antithrombin III, and factor V Leiden [FVL] mutation) over a period of 10 years (2005 to 2014). RM patients were divided in to three groups. Group I (only 1st trimester loss), group II (only 2nd and 3rd trimester), and group III (mixed). Each group comprised of the following numbers of patients respectively: I, 24; II, 2; III, 14. Heterozygous FVL mutation was found in 10% (4/40) cases. PS deficiency was detected in 2.7% (1/37) cases. In the present study FVL and PS were seems to be associated with a subset of patients however further studies with larger numbers of patients are recommended for better evaluation.
M-QAM BER and SER Analysis of Multipath Fading Channels in Long Term Evolutions (LTE)
Patteti Krishna,Tipparti Anil Kumar,Kalitkar Kishan Rao 보안공학연구지원센터 2016 International Journal of Signal Processing, Image Vol.9 No.1
Cellular Mobile Communications have become an essential part of the world telecommunications. However, the systems suffer from multipath propagation effects. In this paper, we calculate the probability of symbol error rate and bit error rate of M-ary Quadrature Amplitude Modulation (M-QAM) over slow, flat, identically independently distributed Rayleigh fading and additive white gaussian channels. Since the fading is one of the major constraints in wireless communications, then diversity modulation technique is used for the efficient transfer of message signals. The simulation results show between SER/BER and energy per bit to noise spectral density.
microRNAs in Mycobacterial Infection: Modulation of Host Immune Response and Apoptotic Pathways
Riddhi Girdhar Agarwal,Praveen Sharma,Kishan Kumar Nyati 대한면역학회 2019 Immune Network Vol.19 No.5
Our current knowledge of mycobacterial infections in humans has progressively increased over the past few decades. The infection of Mycobacterium tuberculosis causes tuberculosis (TB) disease, which has reasoned for excessive morbidity and mortality worldwide, and has become a foremost issue of health problem globally. Mycobacterium leprae, another member of the family Mycobacteriaceae, is responsible for causing a chronic disease known as leprosy that mainly affects mucosa of the upper respiratory tract, skin, peripheral nerves, and eyes. Ample amount of existing data suggests that pathogenic mycobacteria have skilled in utilizing different mechanisms to escape or offset the host immune responses. They hijack the machinery of immune cells through the modulation of microRNAs (miRs), which regulate gene expression and immune responses of the host. Evidence shows that miRs have now gained considerable attention in the research, owing to their involvement in a broad range of inflammatory processes that are further implicated in the pathogenesis of several diseases. However, the knowledge of functions of miRs during mycobacterial infections remains limited. This review summarises recent findings of differential expression of miRs, which are used to good advantage by mycobacteria in offsetting host immune responses generated against them.

The study was to see the effect of administration of ruminal fungi on feed intake, growth rate, rumen fermentation and nutrient digestion of calves (Tharparkar$\times$Holstein-Friesian, average age: 10 months, average body weight: 130 kg). The 6 calves in first group were fed a mixture consisted of 50% wheat straw and 50% concentrate (Maize 62%, Groundnut cake 35%, Mineral mix. 2% and Common salt 1%) along with 1 kg green oats $animal^{-1}$ $day^{-1}$ while second group calves were fed the above-mentioned diet in addition to a dose of 160 ml ($10^{6}$ CFU/ml) fungal culture $calf^{-1}$ $week^{-1}$. The average dry matter intake per day was slightly lowered in fungal fed calves yet feed conversion ratio was higher. The average daily weight gain was significantly higher (15.37%) in fungal administered group as compared to control. The nutrient digestibility was increased for crude fibre, NDF and ADF with fungal administration. Digestible energy value of straw-based diet in terms of percent TDN also increased. The pH and $NH_{3}$-N were lower whereas TVFA, total-N, TCA-N and number of zoospores were higher in rumen liquor in fungal administered group.

Objectives: Acupuncture treatments are safe and effective for a wide variety of diseases involving autonomic dysregulation. Heart rate variability (HRV) is a noninvasive method for assessing sympathovagal balance. The low frequency/high frequency (LF/HF) spectral power ratio is an index of sympathovagal influence on heart rate and of cardiovascular health. This study tests the hypothesis that from rest to 30% to 50% of peak oxygen consumption, the nonlinear Conte-Zbilut-Federici (CZF) method of computing the LF/HF ratio is a more reliable index of changes in the HRV than linear methods are. Methods: The subjects of this study were 10 healthy young adults. Electrocardiogram RR intervals were measured during 6-minute periods of rest and aerobic exercise on a cycle ergometer at 30% and 50% of peak oxygen consumption ($VO_{2peak}$). Results: The frequency domain CZF computations of the LF/HF ratio and the time domain computations of the standard deviation of normal-to-normal intervals (SDNN) decreased sequentially from rest to 30% $VO_{2peak}$ (P < 0.001) to 50% $VO_{2peak}$ (P < 0.05). The SDNN and the CZF computations of the LF/HF ratio were positively correlated (Pearson's r = 0.75, P < 0.001). fast Fourier transform (FFT), autoregressive (AR) and Lomb periodogram computations of the LF/HF ratio increased only from rest to 50% $VO_{2peak}$. Conclusion: Computations of the LF/HF ratio by using the nonlinear CZF method appear to be more sensitive to changes in physical activity than computations of the LF/HF ratio by using linear methods. Future studies should determine whether the CZF computation of the LF/HF ratio improves evaluations of pharmacopuncture and other treatment modalities.
