- "Sawdust particles soon after emission from the cutting machine usually move dynamically with transformation in some dimensions. This paper models the sawdust particle motion as a two dimensional transformation system of continuous time series. Cost could be saved using this approach instead of utilizing dynamic systems that depend on time history Two dimensional graphical representation of continuous time series of Duffing's dynamic system for sawdust particles was investigated with emphasis placed on application to sawdust particle motion and the saw machines. Pr~liminary studies were made using the harmonic functions, F(t) = Cos(wt) and F(t) = Sin(wt), for their familiarity in both science and technology communities. The solution to Duffing's model equation for the sawdust particles was sought from displacement and velocity perspectives, using the Runge-Kutta Algorithm. Linear transformation that guarantees non-negative values of time series was implemented. This was followed by the respective computation of the x- and y-components of the resulting time series values of the sawdust movement using a 21tmodulated time measured in radians. The graphical representations of the x- and y-components compared well quantitatively and qualitatively with the corresponding phase plots. The feasibility of modelling sawdust dynamics as emission from band saws was therefore demonstrated here, in approaches that thus advance knowledge of sawdust emission studies. " 1 results 1

- Aim: To assess the feasibility and effectiveness of depot antipsychotic (flupentixol decanoate) combined with an assertive monitoring programme (AMP) in first-episode schizophrenia. Methods: This was a prospective, non-comparative, longitudinal study conducted over 12 months assessing patient acceptance, adherence, outcome in domains of psychopathology, functionality and quality of life, and tolerability. Results: Of 207 participants, 149 (72%) completed 12 months of treatment. Acceptance of and adherence to depot was good. Treatment response was achieved by 170 (82%) participants and remission by 124 (60%). Thirty-three (19%) responders relapsed and10(5%) participants met a priori criteria for treatment resistance. Treatment was generally well tolerated. Conclusions: Combination of depot antipsychotic with an AMP maybe an effective and safe intervention linearly phase of schizophrenia, and may be particularly suitable for resource constrained settings. 1 results 1

- Background: As frequent viral outbreaks continue to pose threat to public health, the unavailability of antiviral drugs and challenges associated with vaccine development underscore the need for antiviral drugs discovery in emergent moments (endemic or pandemic). Plants in response to microbial and pest attacks are able to produce defence molecules such as antimicrobial peptides as components of their innate immunity, which can be explored for viral therapeutics. Methods: In this study, partially purified peptide-rich fraction (P-PPf ) were obtained from aqueous extracts of seven plants by reverse-phase solid-phase extraction and cysteine-rich peptides detected by a modified TLC method. The peptide-enriched fractions and the aqueous (crude polar) were screened for antiviral effect against three non-polio enterovirus species C members using cytopathic effect reduction assay. Results: In this study, peptide fraction obtained from Euphorbia hirta leaf showed most potent antiviral effect against Coxsackievirus A13, Coxsackievirus A20, and Enterovirus C99 (EV-C99) with IC50< 2.0 μg/mL and selective index ≥ 81. EV-C99 was susceptible to all partially purified peptide fractions except Allamanda blanchetii leaf. Conclusion: These findings establish the antiviral potentials of plants antimicrobial peptides and provides evidence for the anti-infective use of E. hirta in ethnomedicine. This study provides basis for further scientific investigation geared towards the isolation, characterization and mechanistic pharmacological study of the detected cysteine-richpeptides. 1 results 1

- Chaos is one of the most important behavioural modes exhibited by dynamical systems and refers to the unpredictable, seemingly random, motion of trajectories of a dynamical system. In recent time, non-linear dynamics and chaos have become familiar in the technical vocabulary of most sciences and technology due to the various applications of chaos in these areas. Chaotic systems display chaotic behaviours only for specific range of values of their parameters. It is therefore important to understand the chaotic features as well as parameter values resulting in its emergence in systems. In this paper, the emergence of chaos in six chaotic systems was demonstrated using Simulink with specific initial conditions and parameter values. The simulation results obtained in form of time series illustrated noise-like waveforms which were unpredictable even after a long interval of time, while the phase portraits were irregular and sponge-like in appearance. The noise-like and unpredictable trajectories as well strange attractors observed clearly demonstrated the emergence of chaos the chosen parameter values. 1 results 1

- Cross River (CR) andQua Iboe River (QIR) in AkwaIbom State are prone to pollution from diverse sources including urbanisation and agricultural activities. The state and national agencies are exploiting the river banks for establishing industrial and recreational parks. Due toscarcity of data on the pollution and human exposure risks of these rivers, there is need to establish their pollution status. This work was aimed at determining the physicochemical characteristics, metal speciation in surface water and sediments and saturation indices on these rivers. Surface water and sediment samples were collected monthly between June 2009 and May 2010 from six stations with high human activities along CR (Okopedi, Ayadehe, Nwaniba, Oron, James-Town, Ibaka) and QIR (Iwuokpom1, Iwuokpom2, Iwuochang, Eketai, Atabong, Marina). Sampling was done by compositing three grab samples from each station giving a total of 144 each of water and sediment samples. Selected pollution parameters and trace metal concentrations were determined using APHA methods. A thermodynamic model, pH-Redox-Equilibrium-Computer programming language-Interactive (PHREEQCI), was employed to determine some metal species and saturation indices of associated mineral phases in water samples. The relationship between metal speciation in water with sediment in terms of bioavailability was evaluated using the European Union Binding Corporate Rules reference method. Data were analysed using coefficient of variation and Pearson correlation at p = 0.05. The concentrations (mgL±1) of alkalinity (36.1±19.2, 61.3±35.1), dissolved oxygen (7.6±1.2, 6.4±0.9), nitrate (12.3±9.6, 4.6±2.9), chloride (880±520, 860±140), phosphate (0.05±0.02, 0.10±0.02) and sulphate (30.9±9.0, 36.2±6.6) in the rivers (Cross, Qua Iboe) respectively were obtained. The concentrations (mgL±1) of Cd(0.02±0.01, 0.04±0.05), Pb(0.02±0.01, 0.03±0.03), and Ni(0.05±0.05, 0.06±0.08) in water exceeded the WHO limits while those of Cr(0.02±0.02, 0.04±0.03), Cu(0.04±0.02, 0.07±0.07) and Zn(0.11±0.07, 0.20±0.09) were below the limits. Metal variability in water forCross River was higher for Cd (81.3%) and Ni (94.0%). There were strong correlations for Cr/Co (r=0.9), Cu/Co (r=0.9) and Ni/Co (r=0.8) indicating point source of metal pollution. The dominant metal species for the rivers were the free hydrated species of Co2+(97.0, 97.7%); Cu2+(82.8, 70.2%); Ni2+(98.1, 97.6%); Pb2+(60.0, 62.0%); CdCl+(82.2, 82.3%) and CrOH2+(53.1, 58.7%). The concentrations (�gg�1) of Cd, Pb, Ni, Cr, Cu, Zn and Co in sediments of Cross and Qua Iboe Rivers correspondingly were 0.50±0.24, 1.59±0.87; 59.3±14.2, 13.4±6.2; 6.60±2.3, 4.9±3.0; 15.9±5.3, 20.9±14.0; 71.8±17.3, 45.3±16; 129±12, 122±18; 7.60±2.3, 5.5±3.0. The non-residual sediment fraction of Cd, Pb and Cu in Cross and Qua Iboe Rivers were 89.3 and 88.7%, 62.4 and 64.0%, and 83.1 and 83.3% respectively. Saturation indices showed supersaturation for CdCr2O4, CuCr2O4, PbHPO4 and Pb-pyromorphite minerals. There was a dominance of bioavailable fractions bound to Fe/Mn-oxide and organic/sulphide components. Comparison with PHREEQCI data showed higher metal bioavailability in water than in the sediments. The metal pollution levels in the two rivers may be due to anthropogenic activities in the rivers. The occurrence of bioavailable metals suggests potential health risk from metal toxicities. 1 results 1
