“Children’s First Experiences in School” A Reflection for Parents and Teachers
Authors: Richards Delia Robinson 
Published: February 2021

Children are products of their environment. When the learner comes to school, they bring their environment with them. It is important that educators help the learner adjust to the school environment and make the learner feel a part of the school. Allowing the children to develop the classroom rules, accommodating, and involving parents /family in the school environment is the beginning of a collaborative teaching and learning experience. Nurturing, bonding, and scaffolding with the urban learner is pivotal for the learner to excel to their fullest potential. In addition, appreciating and respecting cultural diversity is critical in helping the children reach their optimal potential.

Published: February 2021

Handover process is a very essential process in the Global System for Mobile Communication system (GSM). Its study is one of the major key performance indicators in every GSM network, and its linked to the quality of service of an each service provider strives to attain. The failure of the handover process is regarded as the drop of quality of service which in turn dissatisfies the customers. This study, contributes more on improving call drop rate in general, reduce handover failure rate and thus save on upgrade costs, this will be beneficial to GSM service providers to easily optimize their network faults relating to the resource management. In this paper, dynamic guard channel algorithm is presented that was developed using JAVA Software. This algorithm prioritizes the handover calls over the new originated calls. All handover calls are ongoing calls and if they are dropped it causes frustrations. Matlab was used to compare simulated results to the other schemes by use of graphs and charts. From this paper we were able to establish and come up with a definitive solution to the handover crisis befalling telecommunication companies.

Study of the Secondary Flow in Aircraft Engine Compressor Disks using Computational Fluid Dynamics
Authors: Ahmed Syed Naveed , Reddy P. Ravinder , Venkatesh Sriram 
Published: February 2021

The compressor disks of an aircraft engine which operate at very high rotational speeds are exposed to significant temperature gradients. These temperature gradients induce thermal stresses into the rotating disks which along with the existing dynamic stresses significantly reduce their useful field life. Hence it becomes essential to reduce the disk temperature gradients by utilizing a certain percentage of the compressor core flow known as the secondary flow for either heating or cooling these rotating parts. But this extraction of the compressor core flow results in a higher engine fuel burn for a given engine thrust. Hence the need arises for a better utilization of the secondary flow to effectively reduce the temperature gradients of the rotating compressor disks. As the secondary flow thermal phenomenon inside the rotating compressor disk cavities is very complex and due to it’s direct impact on the life expectancy of the disks it becomes critical to understand it’s thermo-fluid behaviour by the effective use of available Computational Fluid Dynamic tools. In the current study the secondary flow through the compressor disk cavities is simulated using Computational Fluid Dynamics (CFD) and the results are analysed and reported. The analysis of these results help in a better understanding of the distribution of the flow and the variations of the thermal fluid parameters across the secondary flow system. These results are also later used as thermal boundary conditions in the Finite Element model (FEM) to study the impact of various engine design parameters on the disk temperature gradients after being validated by the experimental results. The findings from this computer aided investigation offers support in make design improvements aimed at lowering the disk temperature gradients and enhancing their useful field life

Published: February 2021

BACKGROUND: Accumulating evidence highlights that long noncoding RNA (lncRNA) DSCAM-AS1 play a key regulatory role in different stages of cancer development and progression. This study aimed to investigate whether the expression of DSCAM-AS1 is deregulated in breast cancer. MATERIALS AND METHODS: The relative expression of DSCAM-AS1 was measured in fifty breast cancerous and matched adjacent non-neoplastic tissue samples using quantitative real-time polymerase chain reaction (qPCR) technique. The association between DSCAM-AS1 expression and patients’ clinicopathological features was evaluated. Sensitivity and specificity of the DSCAM-AS1 expression for diagnosing breast cancer was obtained by the receiver operating characteristic (ROC) curve analysis. RESULTS: Our results showed that the expression of DSCAM-AS1 was significantly up-regulated in breast cancerous tissues compared with the matched adjacent non-neoplastic tissues (P < 0.05). Furthermore, we observed a significant association between the DSCAM-AS1 expression and lymph node metastasis (P = 0.011) but no other clinicopathological characteristics (P > 0.05). ROC curve analysis resulted in an area under the curve (AUC) of 0.67 and showed that the DSCAM-AS1 expression level may discriminate cancerous and non-cancerous tissues with 68% sensitivity and 76% specificity. CONCLUSION: This study provides further evidence that the expression of DSCAM-AS1 is deregulated in breast cancer and highlights its potential in breast cancer development.

Published: February 2021

Background: Prednisone is a common treatment for myasthenia gravis (MG), and osteoporosis is a known potential risk of chronic prednisone therapy. Objective: Our aim was to evaluate the risk of serious fractures in a population-based cohort of MG patients. Methods: An inception cohort of patients with MG was identified from administrative health data in Ontario, Canada between April 1, 2002 and December 31, 2015. For each MG patient, we matched 4 general population comparators based on age, sex, and region of residence. Fractures were identified through emergency department and hospitalization data. Crude overall rates and sex-specific rates of fractures were calculated for the MG and comparator groups, as well as rates of specific fractures. Adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox regression. Results: Among 3,823 incident MG patients (followed for a mean of 5 years), 188 (4.9%) experienced a fracture compared with 741 (4.8%) fractures amongst 15,292 matched comparators. Crude fracture rates were not different between the MG cohort and matched comparators (8.71 vs. 7.98 per 1000 patient years), overall and in men and women separately. After controlling for multiple covariates, MG patients had a significantly lower risk of fracture than comparators (HR 0.74, 95% CI 0.63–0.88). Conclusions: In this large, population-based cohort of incident MG patients, MG patients were at lower risk of a major fracture than comparators. The reasons for this finding are unclear but may highlight the importance osteoporosis prevention.
Cleistocalyx nervosum var. paniala seed extracts exhibit sigma-1 antagonist sensitive neuroprotective effects in PC12 cells and protects C. elegans from stress via the SKN-1/NRF-2 pathway
Authors: Brimson James Michael , Prasanth Mani Iyer , Isidoro Ciro , Sukprasansap Monruedee , Tencomnao Tewin 
Published: February 2021

BACKGROUND: Cleistocalyx nervosum var. paniala ( C. nervosum) is a plant that produces berries that are popular as a health food in Thailand. In previous studies we have identified C. nervosum fruit extracts to have anti-aging and anti-stress properties in C.elegans OBJECTIVE: Evaluate the neuroprotective properties of C. nervosum seed extracts and investigate the mechanisms behind their neuroprotective properties. METHODS: PC12 cells were differentiated using NGF and treated with amyloid-β (Aβ)(25–35) creating a model of neurodegeneration, in which C. nervosum seed extracts were tested for neuroprotective properties. Cell viability was measured after 24 hours of using the MTT assay. We also measured the lifespan and “health span” of various C.elegans mutants and the wild type. RESULTS: C. nervosum seed extract protects PC12 cells from Aβ(25–35) toxicity, as well as potentiating NGF induced neurite outgrowth in the same cell line potentially under the control of the sigma-1 receptor. C. nervosum seed extracts have anti-aging properties in C. elegans, causing a significant increase in lifespan of Aβ expressing C. elegans and wild type worms. This appears to be regulated by SKN-1/NRF-2, possibly via the sigma-1 receptor. The DAF-16 pathway is also involved in the lifespan extension of C. elegans. CONCLUSIONS: C. nervousum has been often used as a functional food. We have shown its neuroprotective properties which are sensitive to sigma-1 receptor antagonism in PC12 cells, and involve the SKN-1/NRF-2 and DAF-16 pathway in C.elegans. Further research into the active compounds may lead to future drugs for preventing or treating neurodegenerative disease.

Authors: Ritenour Mark A. , Wardowski Wilfred F. , Tucker David P. 
Published: February 2021

Irrigation and fertilization are important components of commercial citrus production. Irrigation is necessary to adequately replenish soil water lost through evaporation and transpiration. Fertilizers replace nutrients removed during harvest and through leaching. They also maintain tree growth and vigor. Optimum management of both is critical for obtaining maximum yield. Irrigation and fertilization practices can also have significant impacts on fruit quality and shelf life during harvest, packinghouse operations, storage, and distribution. These include effects on fruit color, texture, disease susceptibility, juice composition, and the development of physiological disorders. 1.
