Abstract
Acacia nilotica is an important agroforestry specie, which is used in both compact and linear forms. The objective of the current study was to evaluate the effect of compost on the growth performance and biomass production of A. nilotica. Completely randomized design (CRD) was used to analyze the variations among several growth morphological traits. Two parallel trials, pot trial (seedlings), field trial (saplings) were conducted simultaneously. Compost and litter mixture were applied in mentioned trials. Following treatments were used: T0 – control; T1 - 25% of compost and 75% of nursery soil; T2 - mixture of 50% nursery soil and 50% compost; T3 - mixture of 75% compost and 25% of nursery soil; T4 - where 100% compost was applied. Increase in plant growth was observed with the increases in the amount of compost mixture. In field trial maximum plant height, shoot length, root length, rootshoot ratio and biomass production was observed when 100% compost level was applied, while minimum was observed without any compost appli-cation. In pot trials, the maximum plant height, rootshoot ratio and biomass production was recorded when 75% compost level was applied. Overall, Acacia performed better with 100% of compost application in field trail and 75% of compost application in pot trial. The results of this study demonstrated the positive effects of compost on the growth of Acacia. The seedling development was improved considerably with different levels having greater percentage of organic fertilizer and it was concluded that compost improves soil fertility and it should be used as organic fertilizer in farming and forestry practices for improving crop growth and yield.

Published: October 2019

Abstract
Cardiovascular Disease (CVD) is considered as one of the principal causes of death in the world. Over recent years, this field of study has attracted researchers’ attention to investigate heart sounds’ patterns for disease diagnostics. In this study, an approach is proposed for normal/abnormal heart sound classification on the Physionet challenge 2016 dataset. For the first time, a fixed length feature vector; called i-vector; is extracted from each heart sound using Mel Frequency Cepstral Coefficient (MFCC) features. Afterwards, Principal Component Analysis (PCA) transform and Variational Autoencoder (VAE) are applied on the i-vector to achieve dimension reduction. Eventually, the reduced size vector is fed to Gaussian Mixture Models (GMMs) and Support Vector Machine (SVM) for classification purpose. Experimental results demonstrate the proposed method could achieve a performance improvement of 16% based on Modified Accuracy (MAcc) compared with the baseline system on the Physionet2016 dataset.

Abstract
Paper aims to enhance the performance of bit error rate (BER) in wireless communication based on the multiple-input multiple-output (MIMO) system of vertical Bell laboratories layered space-time (VBLAST) algorithm. The VBLAST algorithm uses zero-forcing (ZF) and the minimum mean square error (MMSE) to evaluate the BER of wireless communication. MIMO VBLAST techniques function as an adaptive filter and can minimize the interference and multipath fading in the received signal of the channel. Physical layer network coding (PNC) is a new technique used to exploit the spatial diversity of the MIMO VBLAST system to improve the throughput and performance of wireless communication. The bit-error-rate (BER) of proposed VBLAST MIMO with PNC with binary phase-shift keying (BPSK) and quadrature phase-shift keying (QPSK) modulation over the additive white Gaussian noise and Rayleigh fading channel are analyzed. The performance of both BPSK and QPSK modulation in two and four antennas are compared. From the simulation results, it was found that the proposed scheme MIMO VBLAST PNC has a 45.2 % higher BER performance compared to the traditional MIMO scheme with an increase in the BER using MMSE and ZF respectively in both two and four antennas.
Permanent magnet DC motor (PMDC) model identification and controller design
Authors: Alkamachi Ahmed 
Published: October 2019

Abstract
System modeling is a set of mathematical equations that describe the dynamical behavior of a system. It is considered as a primary concern in determining a suitable controller to meet specific requirements. An autoregressive with exogenous terms (ARX) model for a PMDC motor is identified experimentally based on the recursive least square (RLS) method. Adaptive discrete pole placement controller (APPC) is proposed and designed aiming to control the motor revolving speed. For the comparison purpose, a discrete Proportional Integral (PI) controller is also considered in this work. The steady step response, transient response, and the mean squared error (MSE) is counted throughout the comparison. The e ect of the uncertainties in the PMDC model is also investigated in this paper. The result shows a superiority in the performance of the proposed controller compared to that obtained using PI controller.

Authors: Siasios Ioannis D. , Fotiadou Aggeliki , Fountas Kostas , Dimopoulos Vassilios 
Published: October 2019

Background:
Holospinal epidural abscess (HEA) is a rare pathological entity with significant morbidity and mortality rates. Here, we present a 74-year-old male with HEA treated with focal skip laminectomies and catheter irrigation.

Case Description:
A 74-year-old male presented with fever, neck/back pain, and slight weakness in his legs bilaterally (4/5). The patient underwent a magnetic resonance imaging (MRI) of the entire spine showing an epidural collection extending from C5-C6 to the L4-L5 levels. Laboratory studies revealed a leukocytosis and an elevated C-reaction protein level. Blood cultures were positive for methicillin-sensitive Staphylococcus aureus. The patient underwent skip laminectomies at C6 and C7; T2, T3, T5, T6, T8, T9, T10, and T12; and L3, L4, and L5 with catheter irrigation between these levels; this minimized the risk of postoperative kyphosis and instability. His postoperative course was uneventful. Other surgical approaches to HEA described in literature include laminectomy, focal laminectomies, and skip laminectomies.

Conclusion:
In this case of a holospinal HEA, skip laminectomies and catheter irrigation avoided neurological deterioration and delayed spinal instability in a 74-year-old male.
Ultra-early surgery in complete cervical spinal cord injury improves neurological recovery: A single-center retrospective study
Authors: Nasi Davide , Ruscelli Paolo , Gladi Maurizio , Mancini Fabrizio , Iacoangeli Maurizio , Dobran Mauro 
Published: October 2019

Background:
This study evaluated how the neurological outcome in patients operated on cervical spinal cord injury (SCI) was positively influenced by ultra-early surgery (UES).

Methods:
Between 2010 and 2017, 81 patients with traumatic cervical SCI were assigned to the UES group (<12 h after injury; UES) and ES group (surgery between 12 and 48 h after injury; ES). Additional variables evaluated for the two groups included; age, sex, comorbidities charlson comorbidity index (CCI), level of trauma, type of fracture, preoperative and ASIA scores, pre- and post-operative neuroradiological examinations, surgical approaches, and complications.

Results:
Forty-seven of 81 (58.02%) patients exhibited improved neurological function 12 months postoperatively; better outcomes were observed in the UES (29 of 40 [72.5%]) versus ES groups (18 of 41 [43.9%]) (P = 0,009). For the 26 patients with complete cervical SCI (ASIA A), ultra-early surgical decompression was associated with significantly greater neurological improvement versus ES (61.53% vs. 7.69%; P = 0.003). Further, more neurological improvement correlated with the younger age, better ASIA grade at admission, and ultra-early surgical timing (< 12 h) both in the univariate and multivariate analysis (P = 0.037, P = 0.017, and P = 0.005, respectively), while CCI was correlated with improvement only in the univariate analysis (P = 0.005).

Conclusion:
Ultra-early surgical timing in SCI patients appeared to be the most important factor determining the extent of postoperative neurological improvement, particularly regarding motor function recovery.
