Publishing in scholarly journals is not an easy task. It needs patience and a huge effort in order to find your manuscript published in scholarly journals. From our point of view, this mini-review explains the most significant tips that may facilitate this difficult task. Although many researchers fail to find their studies published in impacted journals, others recorded considerable success in this process. This failure may be due to many factors belong to the lab's team, weakness of the research, inability to express their work, defect in the selection of the proper journal, inability to convince the journal's editors and reviewers, and or the negative response to reviewer's comments.

The study was conducted to standardise protocol for sterilisation of different explants of chrysanthemum cvs. “Candid and “Flirt”. Different explants tried were shoot tips, petals, nodal segments and leaf. Carbendazim 200 ppm for 30 minutes + mercuric chloride (0.1%) dip for 2 minutes and final treatment with ethyl alcohol (70%) for 10 seconds proved best for culture asepsis of shoot tips followed by petals, nodal segments and leaf segments in both the cultivar. Carbendazim 200 ppm for 30 minutes + mercuric chloride (0.1%) dip for 2 minutes and final treatment with ethyl alcohol (70%) for 10 seconds proved better sterilisation for culture survival of shoot tips followed by petals, nodal segments and leaf segments in cv. “Candid” whereas, petals followed by leaf segments in case of cv. “Flirt”. This study leads to the standardisation of the shoot tip and petal explants for culture asepsis and survival in chrysanthemum cvs.  “Candid” and “Flirt” and among two cultivars "candid" proved better in sterilisation than "Flirt".

Worried by the massive and persistent failure in secondary school science in Nigeria, the need to research into the effect of process-oriented instructional strategies on spatial abilities and basic science achievement of 9th grade students in Kogi state became very compelling. The study is a quasi-experimental design of pretest, posttest and non-randomized control group type. A total of 702 students (n=316 boys and 386 girls) participated in the study. Three null hypotheses formulated were tested at 0.05 alpha level. While the experimental group received instructions through process-oriented instructional strategies, the control group was through lecture method. Spatial Ability Test (SAT), and Basic Science Achievement Test I and II (BSAT I & II) with reliability coefficients of 0.81, 0.87 and 0.85 were used for data collection. Frequency, percentage, correlation and t-test (for independent respondents) statistics were used for data analysis. It was found that students exposed to process-oriented instructional strategies achieved significantly higher in spatial ability and basic science achievement, among others. Process-oriented instructional strategy was therefore recommended for use by basic science teachers especially when the emphasis is on the development of spatial abilities in learners.

Volumetric Inflow Estimation in a Hydropower Dam Using Autoregressive Integrated Moving Average (ARIMA) Modelling and Altimetric Lake Levels

DOI: 10.9734/CJAST/2018/45157

Background: Several models have been developed for inflow forecasting in reservoirs based on local parameters which may not include an implicit system characteristic like seasonality. Autoregressive integrated moving average (ARIMA) models can be developed to cater for the presence of seasonal and non-seasonal behavior of natural water systems. 

Aims: The present study aims to estimate Volumetric Inflow in a Hydropower Dam using Autoregressive Integrated Moving Average (ARIMA) Modelling and Altimetric Lake Levels.

Study Design: The study was conducted in the Kainji reservoir, West Africa located along the Niger River. This study combines satellite-altimetry-based rating curves with reservoir inflow models that capture the seasonality of upstream characteristics.

Results and Discussion: Seasonal multiplicative ARIMA models were developed based on 27-year inflow records and used to forecast seven subsequent years. Reservoir levels measured by satellite radar altimeters were matched with actual inflows to generate rating curves from which future inflows may then be estimated. The model with the best forecasts relative to actual inflow - a seasonal multiplicative ARIMA (2,1,1) x (2,1,2)12 model – was adopted.

Conclusion: Strong agreements between all three inflow series (actual, model-based, and satellite-based rating curve) suggest that reservoir inflow models can be combined with satellite altimetric for reservoir inflow estimation.

DOI: 10.9734/CJAST/2018/45591

The drying characteristics and the effect of drying air temperature on hot air drying of aloe vera (Aloe barbadensis Miller) were investigated at 50, 60, 70 and 80°C. Five thin layer drying mathematical models (viz. Logarithmic, Newton, Henderson–Pabis, Page and Modified Page) were fit into the experimental moisture ratio for the kinetic study of aloe vera.  Fick’s diffusional model and Arrhenius type of relationship were used to calculate the moisture diffusivity and activation energy respectively. The diffusivity coefficient increased from 1.03 x 10-09 to 1.55 x 10-09 m2 s-1 with the increase in temperature from 50 to 80°C with estimated activation energy and Arrhenius factor of 19.83 kJ mol-1 and 1.98 x 10-07 respectively. Henderson-Pabis model provided the best fit data and can be epitomized as an excellent tool for accessing the drying kinetics of Aloe vera.

Mineral concentration and trace element content in leaves (tender and matured), flowers and pods of M. oleifera grown in Bangladesh was investigated. Atomic Absorption Spectroscopy and UV visible spectroscopy methods were used for this analysis. Content of some of the essential elements such as Ca, Fe, P, Mn, Zn, Cr were found to be present in good amount. On the other hand trace elements Pb, Cd, Cr, and Ni were not detected and Arsenic was found to be present below the toxic limit. Ca is found positively but insignificantly correlated with Mn (r=0.402) and Zn (r=0.435) but negatively and significantly correlated with P (r= -0.697). Mn is positively but insignificantly correlated with Ca (r=0.402). However, Mn is ‍also significantly correlated with Fe (r=0.842) and Zn (r=0.625) which indicates that the percentage of Mn, Fe and Zn in M. oleifera are significantly dependent on each other. Fe and Zn do not show any significant correlation with other observed metals. P is found insignificant and negatively correlated with Mn. The result of this study revealed that all the parts of M. oleifera is a good source of nutritionally important essential elements Ca, P, Mn, Zn and Cr,  and, the leaves and flowers might be the potential sources of Fe supplements for human and livestock.

Problem:  The major problems in the present world include global warming and climate change which adversely affect the environment. There is, therefore, a need to reduce Green House Gas (GHG) emissions by replacing the fossil fuels with renewable energy resources like biogas. Biogas can be generated from various organic waste products or industrial byproducts and used as a renewable and ecofriendly fuel.

Biogas is also used fto provide the energy requirements in rural areas while its byproduct can be used as manure for crop plants as highly rich in nutrients. Indirectly biogas production leads to waste reduction which may be hazardous for the public health. However, there are some obstacles in optimised biogas production. One major problem is limited availability of suitable organic substrates for biogas production.

Objective: Hence, there is a need for new proficient substrates which can improve or enhance the progress of the biogas industry all over the world. The performance of the anaerobic digestion processes is highly reliant on the feedstock characteristics as well as on the activity of the microorganisms involved in different degradation steps.

Methodology: The information related to various aspects of biogas production was retrieved from the several scientific databases such as Google Scholar, PubMed, Science Direct, Scopus, Medline, and AGRICOLA, etc. here we include the data from ninety nine papers to compile this manuscript.

Summary: This review presents an overview of the biogas production and discusses different possible organic substrates used for the biogas production which can be informative towards biogas economy.
