Typha domingensis grass were collected from Hadeija Valley area, Jigawa State, Nigeria. Harvested Typha grasses were chopped manually using cutlass to 2-3 cm and wilted for 48 hours. Molasses and urea were sprinkled accordingly to improve the silage qualities. The mixture were then packed and compressed in a plastic containers of ten kg and sealed using cello tape for each treatments. The silage were left to ferment for 90 days. Four Typha silages were made; T1; 0.5m Typha grass, T2; 0.5m Typha grass + molasses-urea, T3; 1.5m Typha grass and T4; 1.5m Typha grass + molasses-urea laid in a completely randomized design with three replicates. Typha silages were analyzed for chemical composition, mineral contents and fibre fractions. Typha silages have pH values within the optimum range (3.8-4.2). The chemical composition and fibre fractions were significantly (P<...

The research presented here compares the nutritive value and price of Typha silage with a local feed (sorghum straw, Sorghum bicolor (L.) Moench) commonly used in sheep feeding. Three experimental diets were compared: a control diet including 30% of shorgum straw and no Typha); R10: control diet with 10% Typha silage, R20: control diet with 20% Typha silage, and R30: control diet with 30% Typha silage. In all diets Typha silage replaced an equal amount of sorghum straw in the diet. Samples of Typha with height between 0.5 m and 1.5 m were collected in the Hadejia Valley Irrigation Scheme (HVIS), and were analyzed fresh and ensiled either with molasses or with both molasses and urea. Typha (fresh and ensiled) had higher ash than that for sorghum straw, indicating that it could supply more minerals to the ruminant. Fresh Typha had similar neutral detergent fiber (NDF) content than sorghum straw (72.2% and 70.0%, respectively), while ensiled Typha had lower NDF than of sorghum straw (60.2% and 69.8%). Ensiled Typha had similar acid detergent fiber (ADF) content to sorghum straw (47.6% both of them). The added value price of Typha was calculated from the price of sorghum straw (N35 per kg). The addition of molasses and urea increase the price of the Typha silage (N15 and N20/kg for the silage with molasses and with molasses and urea, respectivley). Therefore, the livestock farmers in HVIS could save (N 4,000/ton) by using Typha silage as a replacement for sorghum straw. The use of Typha could be economically interesting and sustainable, but further studies are needed to investigate animal performance with Typha feeding

It provides an efficient mechanism which deters the threats raised by unknown individuals who have deceitful intentions and who aim to deploy unlawful operations such as terrorist attacks. In this context, our proposed BoI model is based on a framework constructed upon an automated machine learning facial expression analysis system which can assist law enforcement agencies who intend to deploy a systematic preventive security approach that aims to reduce the risk of potential unlawful attacks by rogue individuals through the evaluation of their emotional state in relation to their malicious intent.

None of the existing treatment modalities in caring for wounds can yet claim to be the holy grail of wound management. Channa striatus, locally known in Malaysia as Haruan, is a freshwater air-breathing carnivorous fish that is proven to influence the different phases of wound healing. As a medicinal fish, not only does Haruan have a high content of amino and fatty acids, which are essential in collagen fibre synthesis during wound recovery, it also abounds in arachidonic acid and polyunsaturated fatty acids that promote prostaglandin synthesis, a vital component of the healing process. Moreover, its antinociceptive effects could potentially reduce wound pain, an important factor in wound healing. Proteomic studies show that a quarter of the total protein detected in freeze- and spray-dried C. striatus extract are actin, myosin and tropomyosin – all molecules that play a role in the wound healing process. Proteomic profiling also revea...

This popularity made the P2P network susceptible to the spread of malware. The detection of the cause of malware propagation is now critical to the survival of P2P networks. This paper offers a review of the current relevant mathematical propagation models that have been proposed to date to predict the propagation behavior of a malware in a P2P network. We analyzed the models proposed by researchers and experts in the field by evaluating their limitations and a possible alternative for improving the analysis of the expected behavior of a malware spread.

In particular, the implementation of the principle of layered security to harden the network against attacks requires the introduction of checkpoints into the connectivity of components, which inevitably has an adverse impact on network performance. Moreover, advanced intrusion detection systems (IDSs) could be effectively utilised at the checkpoints of the computer network, leading to the analysis and determination of ‘optimal’ security versus performance trade-offs. To this end, a novel quantitative method is proposed for the evaluation and prediction of the aforementioned trade-offs supported by Machine Learning Algorithms (MLAs), such as Random Forest (RF) classifier, Logistic Regression (LR) and Naïve Bayes (NB) algorithms for Network Intrusion Detection Systems (NIDSs). In this context, a minimisation is employed in order to reduce the high dimensionality of datasets using Feature Selection (FS) for the dataset. Moreover, highly weighted features are used to keep false-negative (FN) low and increase the accuracy of MLAs towards the establishment of ‘optimal’ performance versus security tradeoffs. Typical numerical experiments are carried out indicating that the RF classifier is the best MLA, incorporating a subset of 19 selected features and identifying different types of attacks correctly with 99.9% of accuracy.

Evidence suggests that this extrahepatic supply most commonly originates from a right intercostal artery (70–83%) followed by left intercostal, omental and right renal arteries. Thus a comprehensive knowledge of variations in standard vascular anatomy and cognisance of factors influencing or predicting extrahepatic blood supply in HCC is instrumental in ensuring the success of surgical and interventional procedures. We present the unusual case of a 66-year-old male with HCC in Segment I of the liver with aberrant blood supply from the right renal artery in the absence of any risk factors for extrahepatic circulation. He successfully underwent transarterial chemoembolization. There was no evidence of residual disease on repeat imaging.

A retrospective analysis of all patients who underwent left ventricular assist device implantation from 2013 to 2014 was conducted. Postoperative atrial fibrillation, survival, and thrombotic complications were evaluated after surgery. A total of 47 patients (mean age 56.4±12.5 years, 33 male) were included and followed for a median of 331 days. Within 30 days of surgery, 13 (28%) patients developed postoperative atrial fibrillation at mean 7.9±8.5 days. Obstructive lung disease was a predictor of postoperative atrial fibrillation (p=0.01). Postoperative atrial fibrillation was not associated with increased mortality, length of stay, or thrombotic complication within 30 days. Postoperative atrial fibrillation was predictive of recurrent new atrial fibrillation (24% versus 5.5%) after 30 days of left ventricular assist device implantation. Also, postoperative atrial fibrillation was associated with increased risk of ischemic stroke and device thrombosis during follow up (p=0.01). These results show that unlike in other cardiac surgery, postoperative atrial fibrillation does not have a negative impact on early postoperative morbidity or mortality. However, postoperative atrial fibrillation is a predictor for future atrial fibrillation, ischemic stroke, and device thrombosis.

The main objective of this study is therefore to assess the effect of Haruan fish extract (Channa striatus) on chest and leg wounds post-coronary artery bypass grafting (CABG) surgery with the optimum and standard patient care in two groups of randomized patients. Methods: This is a randomized, double blind clinical trial being conducted at the National Heart Institute, Kuala Lumpur. Two randomized groups of similar demographic and co-morbid histories planned for CABG were enrolled into the study. Both groups were blinded to the capsules being given to them pre- and post-operatively. Assessments were also made on wound pain, mobilization and on the health-related quality of life (HRQOL) of patients using the Nottingham Health Profile (NHP). Results: The group that received Haruan capsule showed better would healing...

The main objective of this study is therefore to assess the effect of Haruan fish extract (Channa striatus) on chest and leg wounds post-coronary artery bypass grafting (CABG) surgery with the optimum and standard patient care in two groups of randomized patients. Methods: This is a randomized, double blind clinical trial being conducted at the National Heart Institute, Kuala Lumpur. Two randomized groups of similar demographic and co-morbid histories planned for CABG were enrolled into the study. Both groups were blinded to the capsules being given to them pre- and post-operatively. Assessments were also made on wound pain, mobilization and on the health-related quality of life (HRQOL) of patients using the Nottingham Health Profile (NHP). Results: The group that received Haruan capsule showed better would healing...

Primary hyperhidrosis is a common yet psychologically disabling condition. This study will describe our experience in managing hyperhidrosis via endoscopic thoracic sympathectomy (ETS). Methods: The information was obtained from the patient records from 1st January 2011 until 31st December 2016. Pertinent information was extracted and keyed into a study proforma. Results: 150 patients were operated on but only 118 patients were included in this study. The mean age was 22.9±7.3 years. The majority (54.2%) had palmar-plantar hyperhidrosis and 39.8% had associated axillary hyperhidrosis. Excision of the sympathetic nerve chain and ganglia were the main surgical technique with the majority (55.9%) at T2-T3 level. Mean ETS procedure time was 46.6±14.29 minutes with no conversion. Surgical complications were minimal and no Horner’s Syndrome reported. Mean hospital stay was...

The lack of research investigating spiritual well-being, religiosity, and mental health among Jordanian hemodialysis patients encouraged this research. This study explored levels of spiritual well-being and its associations with depression, anxiety, and stress. A quantitative, cross-sectional correlational study. A sample of 218 Jordanian Muslim hemodialysis patients completed a structured, self-administered questionnaire. The data were analyzed using descriptive statistics and linear multivariate regression models. The hemodialysis patients had, on average, relatively low levels of spiritual well-being, moderate depression, severe anxiety, and mild to moderate stress. The results of the regression models indicated that aspects of spiritual well-being were negatively associated with depression, anxiety, and stress, but only existential well-being consistently...
