Authors: Ezeamaka Cyril Kanayo , Oluwole Olumide Akinwumi 
Published: November 2016

Abuja Master Plan provided development of adequate Green Areas and other Recreational Facilities within the Federal Capital City (FCC), as part of its sustainability principles and provided for these recreational facilities within each neighborhood (FCDA, 1979). However, there have been several recent foul cries about the negative development of recreational facilities and the abuse of the Master Plan in the FCC. The motivation for carrying out this study arose from the observation that recreational facilities in Phase 1 of the Federal Capital City Abuja are not clearly developed as intended by the policy makers and thus, the need to identify the recreational facilities in the Phase 1 of FCC and observe their level of development as well as usage. The field survey revealed that the Central Business District and Gazupe have higher numbers of recreational facilities with 45 and 56. While Wuse II (A08) and Wuse II (A07) Districts have lesser recreational facilities with 10 and 17. The field survey further revealed that all the districts in Phase 1 have over 35% cases of land use changes from recreational facilities to other use. The survey shows that over 65% of these recreational facilities are fully developed. The study also shows that just about 11% of the recreational sporting facilities were developed in line with the Abuja Master Plan in Phase 1. The study revealed that recreational facilities in Phase 1 of the FCC, Abuja has not being developed in compliance with the Abuja Master Plan.

Published: November 2016

This article is discussing on how the rise and tide of Minangkabau traditional trading occur in Kuala Lumpur. The research focused on four areas in Kuala Lumpur, Chow Kit, Kampung Baru, Kampung Dato’ Keramat and Mesjid India area, reveals that there are some small stalls of Minangkabau traditional trading are now owned by another Indonesian ethnicity such as Acehenese and Boyanese tribe. Meanwhile, some of the businesses are still possessed by Minangkabau tribe such as Nasi Padang and textile trading. The phenomenon is affected by the lack of business innovation, capital, local competitor and the fact that they are unable to follow the trend in business. Even though, there are some of well-developed traditional business run by Minangkabau people in Kuala Lumpur due to the existence of marketing creativity, innovative items, and the conducive partnership with another Minangkabau entrepreneurs in the textile merchant in form of kiosk or arcade in Mesjid India area that has connection with another counterpart of the nationwide including Sabah and Sarawak.

Leadership has an important role in the organization as leader is in charge of supervising and controlling the course of an organization. Ability to lead in mobilizing and empowering employees will affect the performance of the organization. This behavior has a significant impact on the attitudes, behavior and performance of employees. The results of the study showed there is a significant relationship between characteristics such as age (p = 0.004), education(p = 0.034), work experience (p = 0.000), the experience of the organization (p = 0.000), and educational hierarchy (p =0.000) for leadership flexibility. Sex variable is not significant to the leadership flexibility (p = 0.801). There is a relationship with the flexibility of directive leadership style (p = 0.027), supportive leadership style (p = 0.046), and participative leadership style (p = 0.009) with the flexibility of leadership. There is aso a relationship between achievement-oriented leadership style and leadership flexibility (p = 0.000). There is a relationship between the individual characteristics of leadership style and versatility with variable: educational level of leadership (p = 0.021; OR = 19.265). The result suggests that we need more organized seminars / work shop / scientific studies that stimulate the realization of learning about leadership flexibility in improving the performance of the District/City Health Office and it is necessary to study theperformance of the head of the Department of Health assessment intensively and periodically

Neural stem cell niches in the adult mammalian brain
Authors: Tsupykov O. 
Published: November 2016

Stem cells of the central nervous system have received a great deal of attention in neurobiology in the last decade. It has been shown that neurogenesis occurs in the postnatal period in specialized niches of the adult mammalian brain. The niche is a key regulator of stem cell behavior. Recent data underscore the complexity and heterogeneity of the different components of the niche, and the presence of local signaling microdomain. The review is devoted to recent views on the structural organization of neurogenic niches and regulatory factors involved at different stages of neurogenesis in the postnatal period. Understanding of stem cells behavior in the niches can serve as a basis for determination of these cells function in the adult brain.

Published: November 2016

Ischemic stroke is one of the leading causes of mortality and disability worldwide. Dispite the progress of medical knowledge and technologies, the rate of permanent neurological impairment in patients after stroke remains high and effective strategy of restorative treatment is still at the stage of experimental development. Restoration of nervous system functions after stroke implies the activation of endogenous reparative processes, such as angiogenesis, using sources of regenerative medicine, including cell and tissue transplantation. Development of optimal and safe methods of neurotransplantation for stroke is one of the priorities of experimental research in this field.Purpose: to study the effect of post-stroke angiogenesis, stimulated by transplantation of cell suspension from embryonic nervous tissue (TCS-ENT) and bone marrow (TCS-BM), on restoration of motor functions in rats with experimental stroke.Materials and methods. 160 adult (3-4 months old) outbred albino rats weighing between 280-320 g were divided into groups and subgroups depending on the experimental procedure: with isolated middle cerebral artery occlusion (MCAO), intracerebral allotransplantation of cell suspension from embryonic nervous tissue (MCAO + TCS-ENT),intracerebral autotransplantation of cell suspension from bone marrow (MCAO + TCS-BM) or phosphate-buffered 0.9 % saline infusion (MCAO + PBS) on the 2nd day after MCAO. MCAO was conducted using the modified method of intraluminal monofilament occlusion with blocking of collaterals. Volume of infarction zone was estimated using TTC staining on 7th and 14th day (n = 5 from each group on each day), number of vessels in periinfarct zone was calculated by immunohistochemical staining for CD34 on 7th, 14th and 28th day (n = 6 from each group on each day) after MCAO. Motor deficit was assessed by ledged tapered beam-walking test on 1st, 3rd, 7th, 14th, 21st and 28th day after MCAO (n = 18 from each group on each day).Results.TCS-BM caused the increase in the number of vessels in the periinfarct zone in dynamics, most prominent on 28th day, and decrease in the volume of infarction zone in comparison with other experimental groups, starting on 7th day after MCAO. TCS-ENT and TCS-BM resulted in regression of motor deficit, starting from 3rd and till 28th day after MCAO. The degree of limb motor asymmetry in rats negatively correlated with the number of vessels in periinfarct zone.Conclusion. Transplantation of cell suspension from embryonic nervous tissue and bone marrow promotes the regression of motor impairments in experimental animals due to angiogenic effect, which is more prominent in case of TCS-BM.

Published: November 2016

We describe the state of the immune system at the late stage of 1,2-dimethylhydrazine (DMH)-induced colon cancer and after administration of placenta-derived multipotent cells (PDMCs). The spleen and thymus indices did not differ among the groups of intact and DMH-treated rats and were not affected by the administration of placenta-derived multipotent cells following the DMH treatment. Moreover, no difference in spontaneous or stimulated phagocytic activity of peritoneal macrophages was observed between healthy rats or the animals with DMH-induced colon cancer (with or without the administration of PDMCs). However, the proliferation of the T cells in the spleen was lower in rats with colon cancer regardless of the administration of PDMCs. Similarly, no changes were observed in the cell cycle distribution of proliferating spleen cells after stimulation by lipopolysaccharide.Conclusion. Our data demonstrate the absence of the active reaction by peritoneal macrophages and spleen cells to a colon cancer at mid/late stage. Additionally, the administration of PDMCs does not result in a measurable anti-tumor immune response.

Published: November 2016

Abstract
A series of novel dialkyl disulfonate Gemini surfactants (Cn-GSBS, n = 8, 12, 14, 16, n is the carbon number of the hydrophobic chain) was synthesized from cyanuric chloride, aliphatic amine, ethylenediamine, N,N'-dimethyl-1,3-propyldiamine and sodium 2-chloroethanesulfonate. The chemical structures of the prepared compounds were confirmed by FT-IR and 1H NMR. The critical micelle concentrations (CMC) in aqueous solutions at 25°C were determined by surface tension method. The CMC value decreased with increasing length of the carbon chain. The CMC reached a minimum as low as 5 × 10−5 mol · L−1 for C16-GSBS. The interfacial tensions (IFT) between Daqing crude oil and Cn-GSBS surfactant solutions were also measured. The effects of the concentration of Na2CO3, the concentration and carbon chain length of Cn-GSBS on the IFT of crude oil-water were investigated in detail. The results show that, for the aqueous surfactant system containing the weak base Na2CO3, oil-water interfacial tension can be reduced to 10−2 mN m−1 orders of magnitude. The results also indicate that with the increase of surfactant concentration and the chain length, the oil-water interfacial tension decreased markedly, which indicates that Cn-GSBS surfactants have a good interface activity. These surfactants are good candidates for weak base-surfactant-polymer EOR process.

Abstract
We report the phase states in dodecyltrimethyl ammonium bromide/water (DDTMABr–H2O) lyotropic liquid crystalline system. The temperature-concentration phase diagram of this system has been determined. Isotropic micellar L1 phase, nematic-calamitic NC and hexagonal E mesophases have been observed in DDTMABr/H2O system. Dynamics of transformations of magnetically induced textures in NC and E mesophases has been investigated. Temperature and concentration dependences of the refractive index in the L1 phase, NC and E mesophases have been determined. The appearance of the magnetically induced aligned textures of NC mesophase and changes of the optical birefringence vs. time have been investigated.

Published: November 2016

Abstract
In biodegradable polymer world nanobiocomposites represent a new group of materials filled with inert nanoparticles that shows very interesting properties and the biodegradability of the matrix. In this work we have studied the effect of the polarity of the organomodified montmorillonite and of the elongational flow on the morphology and the rheological and mechanical properties of a new nanobiocomposite with a matrix of biodegradable PLA based blend. The elastic modulus enhances in presence of the nanofiller and this increase is larger and larger with the increment of the orientation. The tensile strength does not show any significant change at the same level of orientation. Moreover, a brittle-to-ductile transition is observed in the anisotropic sample and this effect is again more evident for the nanocomposite. The raise of the interlayer distance is higher for the more polar montmorillonite, even if the two nanocomposites show about the same final interlayer distance and morphology. Some exfoliation is also observed as a result of the application of the elongational flow.

Published: November 2016

Abstract
Graphene stacks/epoxy nanocomposites were produced and characterized in order to analyse the effect of different graphene precursors on cure reaction of a model epoxy matrix. A kinetic analysis of the cure mechanism of the epoxy resin associated to the catalytical activity of the graphite based fillers was performed by isothermal DSC measurements. The DSC results showed that the addition of all graphite based fillers greatly increased the enthalpy of epoxy reaction and the reaction rate, confirming the presence of a catalytic activity of graphitic layers on the crosslinking reaction between the epoxy resin components (epoxide oligomer and di-amine). A kinetic modelling analysis, arising from an autocatalyzed reaction mechanism, was finally applied to isothermal DSC data, in order to predict the cure mechanism of the epoxy resin in presence of the graphite based nanofiller.

Published: November 2016

Background: Cell therapy is a promising approach for Parkinson’s disease (PD). Others and we have previously shown that transplantation of ventral mesencephalic fetal cells into substantia nigra (SN) in an animal model of PD enables anatomical and functional repair of the degenerated pathway. However, the molecular basis of this repair is still largely unknown. Objective: In this work, we studied the expression of several axon guidance molecules that may be implicated in the repair of the degenerated nigrostriatal pathway. Methods: The expression of axon guidance molecules was analyzed using qRT-PCR on five specific regions surrounding the nigrostriatal pathway (ventral mesencephalon (VM), thalamus (Thal), medial forebrain bundle (MFB), nucleus accumbens (NAcc) and caudate putamen (CPu)), one and seven days after lesion and transplantation. Results: We showed that mRNA expression of specific axon guidance molecules and their receptors is modified in structures surrounding the nigrostriatal pathway, suggesting their involvement in the axon guidance of grafted neurons. Moreover, we highlight a possible new role for semaphorin 7A in this repair. Conclusion: Overall, our data provide a reliable basis to understand how axons of grafted neurons are able to navigate towards their targets and interact with the molecular environment in the adult brain. This should help to improve the efficiency of cell replacement approaches in PD.
MODELING THE SOLAR WIND AT THE ULYSSES, VOYAGER, AND NEW HORIZONS SPACECRAFT

Published: November 2016

ABSTRACT
The outer heliosphere is a dynamic region shaped largely by the interaction between the solar wind and the interstellar medium. While interplanetary magnetic field and plasma observations by the Voyager spacecraft have significantly improved our understanding of this vast region, modeling the outer heliosphere still remains a challenge. We simulate the three-dimensional, time-dependent solar wind flow from 1 to 80 astronomical units (au), where the solar wind is assumed to be supersonic, using a two-fluid model in which protons and interstellar neutral hydrogen atoms are treated as separate fluids. We use 1 day averages of the solar wind parameters from the OMNI data set as inner boundary conditions to reproduce time-dependent effects in a simplified manner which involves interpolation in both space and time. Our model generally agrees with Ulysses data in the inner heliosphere and Voyager data in the outer heliosphere. Ultimately, we present the model solar wind parameters extracted along the trajectory of the New Horizons spacecraft. We compare our results with in situ plasma data taken between 11 and 33 au and at the closest approach to Pluto on 2015 July 14.
THE ELECTRON DENSITY IN EXPLOSIVE TRANSITION REGION EVENTS OBSERVED BY IRIS
Authors: Doschek G. A. , Warren H. P. , Young P. R. 
Published: November 2016

ABSTRACT
We discuss the intensity ratio of the O iv line at 1401.16 Å to the Si iv line at 1402.77 Å in Interface Region Imaging Spectrograph (IRIS) spectra. This intensity ratio is important if it can be used to measure high electron densities that cannot be measured using line intensity ratios of two different O iv lines from the multiplet within the IRIS wavelength range. Our discussion is in terms of considerably earlier observations made from the Skylab manned space station and other spectrometers on orbiting spacecraft. The earlier data on the O iv and Si iv ratio and other intersystem line ratios not available to IRIS are complementary to IRIS data. In this paper, we adopt a simple interpretation based on electron density. We adopt a set of assumptions and calculate the electron density as a function of velocity in the Si iv line profiles of two explosive events. At zero velocity the densities are about 2–3 × 1011 cm−3, and near 200 km s−1 outflow speed the densities are about 1012 cm−3. The densities increase with outflow speed up to about 150 km s−1 after which they level off. Because of the difference in the temperature of formation of the two lines and other possible effects such as non-ionization equilibrium, these density measurements do not have the precision that would be available if there were some additional lines near the formation temperature of O iv.
