Authors: Grégoire Isabelle , Butler Bridget 
Published: October 2019

Les programmes Faune sans frontières de la Fiducie foncière de la vallée Ruiter (FFVR) etWildPathsde Cold Hollow to Canada (CHC) illustrent la contribution de la science citoyenne dans l’avancement et la pérennité de projets de conservation et d’aménagement du territoire. Ils prennent place sous différentes plateformes éducatives dans la région des montagnes Vertes de la chaîne des Appalaches, qui chevauche le nord du Vermont et le sud du Québec. Ces programmes invitent les citoyens à prendre part à la science en participant concrètement aux projets en cours sur leur territoire. Parallèlement, ils incitent les scientifiques et experts du milieu à intégrer la science citoyenne dans leurs travaux de recherches en amont des mesures de conservation. En 2017, dans le cadre du vaste projet de Corridor appalachien sur l’identification et la protection des corridors naturels et des passages fauniques de part et d’autre de l’autoroute 10 au Québec, la FFVR a soutenu la formation de dizaines de citoyens au pistage et au suivi faunique. Cette initiative, réalisée en collaboration avec CHC, témoigne des efforts éducatifs communs qui appuient les projets de conservation dans la région transfrontalière des montagnes Vertes.

Published: October 2019

Aims: To assess the effectiveness of triple bagging systems with or without Lippia multiflora leaves on the vitamin-quality of cowpea seeds during storage.
Methodology: Cowpea seeds that have undergone any treatment were collected from producer in the southwest of Côte d’Ivoire. The fresh leaves of Lippia multiflora were collected and dried in sunlight for 7 days in center of Côte d’Ivoire. The storage bags used were obtained from the suppliers to Côte d’Ivoire in Abidjan. All this material was sent to the Laboratory of Biochemistry and Food Sciences, Felix Houphouet-Boigny University, Côte d’Ivoire to perform the experiment. Thus for the experiment realization, a central composite design (CCD) was used. The first factor of CCD consisted to six types of packaging, namely: one control with polypropylene bag (TST), one triple bagging batch (composed of 2 internal layers in independent high density polyethylene 80 mm thick and a woven bag polypropylene) without biopesticide (H0), and four batches (H1, H2, H3 and H4) containing respectively (0.7%; 2.5; 4.3%; and 5%) biopesticide. The second factor, storage time, it included six periods of observation (0; 1; 2; 4.5; 7 and 8 months). HPLC techniques were used for the separation and quantification of β-carotene, α-tocopherol (vitamin E) and the water-soluble vitamins (thiamine, riboflavin, niacin, pyridoxine and folic acid). The estimated daily intake of folic acid (vitamin B9) was also evaluated for Ivorian adult of 70 kg.
Results: The results of vitamin properties indicate a significant influence (P < 0.05) between the type of treatments and shelf life. Multivariate analysis results (PCA and AHC) indicate that the addition of at least 0.7% Lippia multiflora leaves in triple bagging systems makes preservation more efficient and preserves the vitamin quality of the cowpea seeds during 8 months. The contribution to meeting vitamin B9 requirements is palpable when cowpea seeds are stored for up to 8 months in the triple bagging systems associated with the biopesticide.
Conclusion: Cowpea seeds storage in triple bagging systems with Lippia multiflora leaves appears as a method of effective and inexpensive conservation to ensure the vitamin-quality of cowpea.

Published: October 2019

The objectives of the study were to investigate market price structure, market information systems, and credit services for smallholder almond producers around the Samangan and Balkh provinces of Afghanistan. A sample of 125 almond producers were the participants of the study. The primary tool for data collection was a questionnaire conducted by face to face interviews, and the secondary data of the survey collected from various sources, (CSO, FAO reports, government publications, USAID reports, NGOs reports, journals, and websites). Data were analyzed using parametric and nonparametric statistical methods. Results of the study showed that there were significant fluctuations in the average price of different almond varieties between 2014 and 2018 period. Exporters and local traders have the most influence on price determination. According to the study on the market information; 41.6% of producers acquired market information regularly, and 58.4% of them did not receive market information regularly. The research concludes that Afghanistan has a high potential and many opportunities to produce good quality of almond not only for domestic use but also for export to neighbors and more distant countries. This will help the country to take steps towards sustainable horticulture and the improvement of a viable economy.

Published: October 2019

Aims: The aim of this study was to determine the personal experiences of the teacher-participants in the teaching of Technology and Livelihood Education. It also ascertained and met the following objectives: 1) determine the teaching experiences of the TLE teachers; 2) to identify the training needs of TLE teachers; 3) ascertain the challenges faced by the TLE teachers; 3) discover the pedagogy and strategies used by the TLE teachers; and 4) find out the recommendations of the TLE teachers to improve the delivery of the course.
Study Design: Qualitative-phenomenological approach.
Place and Duration of Study: The study was conducted in Sta Cruz National High School, Sta. Cruz, Davao del Sur. The study was conducted for 6 months.
Methodology: The researchers purposely chose all the Technology and Livelihood Education (TLE) teachers. The information were gathered through Focus Group Discussion (FGD).
Results: Six themes emerged from the data analysis. Generally, the teacher-participants found teaching of TLE subject was challenging because the activities were focused on exploration. Moreover, they felt satisfied because they were able to share their knowledge and skills to their students. It implies that the TLE teachers were committed and dedicated to their jobs despite the difficulties they encountered. However, the teacher-participants revealed that generally, they were not sent outside of the school to attend training-seminar for skills enhancement. It is an indication that the school heads lack concern for their teachers’ professional development. In addressing the challenges of the teachers, they collaborate with each other by sharing their resources. Despite the challenges they encountered, they were still optimistic to be globally competitive. It implies that the TLE teachers do not give up easily. They suggested that the school administration needed to develop the participants’ personal character so that their teaching goals were met.
Conclusion: The TLE teachers loved and enjoyed their teaching jobs despite the challenges they faced. However, they clamored to the Department of Education (DepEd) to address their needs such as sending them to trainings and seminar-workshop to enhance their skills and capabilities. To show their dedication to their jobs, they brought their own tools and shared the same to other teachers. Notably, the participants only used three teaching strategies. It shows that TLE teachers lack the knowledge of other teaching strategies. The participants were optimistic that sooner or later their TLE programs are accredited and recognized locally and internationally. This implies that the participants were committed to their jobs. Ironically, they suggested that improvement of the teachers’ self was better than improving the TLE implementation. This shows that the teachers believed that materials can be easily acquired but not the attitude.

Published: October 2019

Background: Cotton (Gossypium hirsutum L.) is grown in more than sixty countries worldwide. It is an important fiber crop in the world. It plays a vital role in our national economy being the source of earning of foreign exchange, therefore, it is considered to be the backbone of the economy of Pakistan. In Pakistan, millions of families are associated with cotton and textile industry for their livelihood.
Results: In this experiment F2 population of the cross L. A. Frego Bract x CIM-600 and their parents was sown in randomized complete block design with three replications during normal growing season of the year 2014 to sort out best performing genotypes for yield related traits. Analysis of variance (ANOVA) revealed that parental and their F2 population showed significant differences for all the observed agronomic traits (plant height, number of monopodia branches, number of sympodial branches, number of bolls per plant, boll weight, ginning out turn, bract type, boll shape, beak size, seed cotton yield, staple length, fiber strength and fiber fineness). Estimation of correlation revealed that seed cotton yield was found positively correlated sympodial branches, fiber fineness and boll weight while ginning out turn, bract type, beak size, staple length and fiber strength were negatively associated with seed cotton yield. Epistasis was not found to be involved in any of the traits.
Conclusion: The correlation and genetics study of various yield related traits provides us useful information for effective selection and sustainable breeding programs. Estimation of broad sense heritability ( ) in F2 populations for different traits vary as following order; ginning out turn>plant height>seed cotton yield>sympodia branches>fiber length>fiber strength>bolls per plant>monopodia branches>boll weight>fiber fineness with heritability 0.90, 0.79, 0.78, 0.75, 0.73, 0.71 0.67, 0.64, 0.63 and 0.50 respectively. Results suggested form heritability and correlation that these traits can be improved either through appropriate selection method or hybrid breeding programme.

Published: October 2019

In this paper, we develop the double step hybrid linear multistep method for solving second order initial value problems via interpolation and collocation method of power series approximate solution to give a system of nonlinear equations which is solved to give a continuous hybrid linear multistep method. The continuous hybrid linear multistep method is solved for the independent solutions to give a continuous hybrid block method which is then evaluated at some selected grid points to give a discrete block method.
The basic numerical properties of the hybrid block method was established and found to be zero-stable, consistent and convergent. The efficiency of the new method was conformed on some initial value problems and found to give better approximation than the existing methods.

Published: October 2019

Background: Left ventricular outflow tract (LVOT) obstruction is a serious complication that can occur after various mitral-valves, surgical or percutaneous, interventions.
It was rarely described in mechanical mitral valve replacements.
Aim: to describe a rare case of late LVOT obstruction after a mitral valve replacement by a low-profile mechanical prosthesis.
Case Presentation: A 48-year woman, with a history of rheumatic mitral valve disease and mechanical mitral replacement by a hemi-disc valve 18 years ago, presented for a recent dyspnea. Echocardiography showed a narrowing of the LVOT, with anterior position of the mitral prosthesis, aorto-mitral annular angulation, septal thickening and remnant native sub-valvular tissue attached to the septum in the LVOT region. This resulted in LVOT obstruction with a peak gradient of 75 mmHg. The heart team opted for a redo surgery, but the surgical decision was refused by the patient.
Discussion: This is a rare case of late LVOT obstruction after mitral valve replacement by mechanical low-profile prosthesis. Preserved native mitral valve tissue, which is the main described cause of LVOT obstruction after mechanical mitral valve replacements was not the unique cause of obstruction in this patient who had also a septal thickening and anterior prosthetic position. Aorto-mitral annular angulation that was identified as a risk factor of LVOT obstruction after trans-catheter mitral valve replacements, should be, probably, also took into account and assessed pre-operatively in patients undergoing surgical mitral replacements.
Conclusion: LVOT obstruction can occur after mechanical mitral replacements event with low profile prosthesis. In patients with identified risk factors of LVOT obstruction, preservation mitral anterior leaflet should be avoided, and preservation of other native mitral tissue should be discussed.

Published: October 2019

Aims: The aim of this study was to explore the metabolic profile of endophytic fungi, Aspergillus terreus (ENF12) isolated from mulberry leaf and evaluate their antifungal efficacy against Macrophomina phaseolina causing charcoal rot disease of mulberry.
Study Design: Completely Randomized Block Design.
Place and Duration of Study: Department of Plant Pathology, Tamil Nadu Agricultural University, Coimbatore, Tamil Nadu during August 2018 to June 2019.
Methodology: The isolation was done by serial dilution and plating method. The culture was identified by utilizing the morphological, microscopical and taxonomical keys as A. terreus. The macroscopic observations such as colony growth, color, texture, pigmentation, growth rate and microscopic observations viz. hyphal and conidial characters were studied. The molecular confirmation was done by DNA sequencing using ITS 1 and ITS 4 primers. The extracellular secondary metabolites were extracted from A. terreus and screened against M. phaseolina by agar well method. The composition of the metabolites was analyzed through GC-MS.
Results: The septate and hyaline mycelium along with aleurioconidia was observed under microscope and based on the DNA sequencing, the ENF12 isolate was identified as A. terreus. The major compounds identified from the extracellular metabolites of A. terreus were tromethamine, benzenediol, tetracosamethyl cyclododecasiloxane, hexadecanoic acid, benzoic acid and pregnatriene. The ethyl acetate extract of the metabolite at 4000 ppm suppressed the growth of M. phaseolina by 77.78%. The pathway analysis revealed that the metabolites are involved in the metabolism of drug development, cellular processes, organismal systems and other pathways. The major identified metabolites and pathways were grouped under biosynthesis of other secondary metabolites, lipid metabolism and energy metabolism.
Conclusion: The endophytic fungi, A. terreus from mulberry could be an effective antifungal agent against M. phaseolina. The metabolic pathway analysis found that the major metabolites identified from A. terreus were also reported in mulberry plants thereby showed the mutual interaction between the host and endophyte.

Published: October 2019

Comparative study of the proximate and mineral components of five local spices (Denniettia tripetala, Monodora myristica, Piper guineense, Syzygium aromaticum, Xylopia aethiopica and) were investigated. The proximate composition revealed that the spices had considerable carbohydrate ranging from 26.2 – 53.4%, crude fibre 13.6 – 23.7%, crude protein 5.67 – 10.9%, but low ash 2.41 – 5.56%, moisture 8.61 – 17.7% and fat 2.34 – 24.3%; except D.tripetala and M. myristica with high moisture content of 17.7% and crude fat content of 24.3%, respectively. The EDXRF analysis shows the presence of mineral elements in the order of K ˃ Ca ˃ Fe ˃ Zn ˃ Sr > Se ˃ Mo ˃ Cu ˃ Mn ˃ Br > Rb. Statistical analysis indicates that there is no significant difference (α = 0.01, 0.05) in the mean contribution of the various sample. However, there is a relationship between the constituents of P.guineense and S. aromaticum, X. aethopica, D. tripetala and the elements (Mn, Br) and (Se, Zn). Generally, the findings indicate that the five spices are good sources of nutrients and mineral elements which could be exploited as great potentials for drugs and/or nutritional supplements.
Climate Change and Man-made Interventions, as Destabilizing Factors of the Coastal Zone: Some Examples of Coasts and Coastal Wetlands in Urban, Peri-Urban Areas and Natural Parks in Greece
Authors: Mertzanis Aristeidis , Mertzani Asimina 
Published: October 2019

The consequences of man-made interventions, Climate Change and future Sea-level rise upon some coastal plains of Greece are examined. Many urban, peri-urban areas and Natural Parks, in low elevation coastal zones in Greece are experiencing or are at risk of Sea-level rise, storm surges, water and soil pollution, saline water intrusion (salinity), coastal erosion and shoreline retreat, floods, and droughts. Sea-level rise could erode and inundate coastal ecosystems and disrupt wetlands, Urban and peri-Urban areas. Characteristic examples of these are the protected wetlands that exist in Greece such as those in the Delta and the river mouth areas of the Sperchios, Alfeios, Arachthos, Louros, and Inois rivers, and the small town of Tolo. Man-made interventions affect the coastal wetland ecosystems, Urban and peri-Urban areas under study. At the same time, an important factor of the destabilization of the ecological balance is the Climate Change and the expected sea-level rise. The main anthropogenic degradation and stresses on the under investigation areas, in recent decades, includes wetland draining, exsiccation of lagoons and lakes, river engineering works, dam construction, intensification and development of agriculture projects, sand mining from riverbeds and beaches, construction of motorways, construction of harbor structures, such as harbors, jetties, seawalls, groins, and breakwaters, rapid urbanization processes, holiday home building and tourist facilities, massive tourism and intense coastal development, water pollution, human-induced land subsidence (uncontrolled water abstraction from surface and underground water tables), and removal of coastal vegetation. Satellite images, maps and systematic in situ observations, integrated with the direct digitizing on the basis of different aged aerial photographs was adopted to estimate the coastal erosion and accretion rates in recent decades (1945-2019) in the areas, under study.

Authors: Agada Akor, Alexander , Daniel Obaseki , Adeniyi Bamidele , Erhabor Gregory Efosa 
Published: October 2019

Background: Chronic obstructive pulmonary disease (COPD) is a chronic respiratory disorder commonly assessed by spirometry and health related quality of life (HRQoL) questionnaires. COPD assessment test (CAT) is a new questionnaire used for HRQoL evaluation especially in a clinic setting.
Aims: To assess HRQoL using the CAT, and to determine the relationship of CAT to other measures of COPD such as pulmonary function test (PFT), dyspnea and six minutes walking distance test (6MDWT) among patients with COPD in Nigeria.
Settings and Design: Cross-sectional study.
Methods: Sixty stable patients with a clinical and spirometric diagnosis of COPD according to the GOLD criteria were recruited into the study. Spirometry was performed according to ATS/ERS guidelines. Health status, dyspnea and functional capacity of the patients were assessed using the CAT questionnaire, modified medical research council (MMRC) dyspnea scale and six-minute walking distance (6MDWT) respectively.
Results: The mean age was 68.8 years ± 10.3. Sixty percent of the study participants were male. The mean BMI was 21.6 ± 4.8 kg/m2, 37(61.7%) of the patients were ex-smokers, 3.3% were current smokers and 35% were never smokers. In terms of frequency of exacerbations 18.3% had ≤ 1 per year and 5.0% had ≥ 2 per year. The CAT was strongly associated with 6MWDT (r = 0.85P < 0.001), FEV1% predicted (r= 0.67, P< 0.001) and with MMRC (r=0.64, p<0.01).
Conclusions: CAT scores correlated well with percent FEV1, dyspnea and exercise tolerance which measures various aspect of COPD. It may serve as an easy to administer sensitive tool in assessing stable COPD in outpatient clinics especially in low resource countries.
Growth and Yield Responses of Curry Plant (Murraya koenigii) to Plant Row Spacing in an Utisol
Authors: Agba O. A. 
Published: October 2019

Curry plant (Murraya koenigii) is one of the most important vegetable spices crops use for food, spice, medicinal and industrial purposes in Nigeria. However, curry plant production in commercial scale in Nigeria is highly constrained by several factors: it is not cultivated in regular farming system mainly due to lack of planting materials and improper plant spacing of this crop among others.
Therefore, field experiments were conducted to determine the effect of different levels of plant row spacing on growth and yield of Curry plant (Murraya koenigii) in Cross River University of Technology, Teaching and Research farm, Department of Agronomy, Obubra, Cross River state, Nigeria in 2017 and 2018 cropping seasons. The experimental design was a randomized complete block design. Treatments were nine plant row spacing (70 x 50 cm, 70 x 70 cm, 80 x 40 cm, 80x60 cm, 90 x 30 cm, 100 x 50 cm, 100 x 70 cm, 100 x100 cm and 100 x130 cm) inter and intra row respectively with four replications. Results showed that plant row spacing have significantly affect the growth and yield of Curry plant. Closer plant row spacing of 70 x 50 cm significantly promoted the tallest plant height and highest leaf area inde x values of curry plant. Fresh and dry leaf yield on per hectare basis were significantly higher in closer plant row spacing than wider row spacing. The highest fresh and dry leaves yield per hectare at 20 weeks after planting (WAP) of 0.9742t/ha and 0.9871t/ha were obtained in closer row spacing of 70 x 50 cm in 2017 and 2018 cropping seasons respectively .
The number of leaves and branches per plant and their fresh leaf yield and dry matter of plant fractions were higher in wider plant row spacing plots. The wide plant row spacing of 100 x 130 cm produced the highest fresh leaf yield per plant of 88.54 g in 2017 and 83.46 g in 2018 cropping seasons. Based on this result farmers are advised to cultivate Curry plant (Murraya koenigii) using the plant row spacing of 70 x 50 or 80 x 60 cm for optimum growth and yield per hectare of the crop under the utisoil condition.
