Potential and orientation for specific tourism products for Dak Nong’s tourism development
Authors: Thanh Loan Ngo , Huu Nghia Le 
Published: April 2020

The Politburo Resolution No.08 on developing tourism into a spearhead economic sector has brought about the advantages of promoting tourism activities by the exploitation of natural resources, reducing poverty, and boosting the citizen’s income. Under these beneficial conditions, Dak Nong province can have more opportunities to develop its local’ s economy by investing in tourism. However, the interrelation of both competition and cooperation with the Central Highlands provinces, Dak Nong, needs to determine its own way to enhance the competitiveness for tourism development.
Based on the theory of tourist destination attractiveness, the authors confirm that designing specific tourism products to promote destination image and to build up the attractiveness of tourist destinations in Dak Nong are necessary. Through assessment of the current situation and potential of tourism development, by using secondary information analyses and in-depth interviews, the result shows that tourism in Dak Nong has not been effectively exploited. In the coming time, specific tourism products based on resources from Dak Nong Geopark can be the key factors to promote the tourism image of Dak Nong.

Published: April 2020

The ethyl acetate extracts of Drynaria quercifolia tubers and leaves were studied for their chemical and biological potentialities. The tuber extract was enriched with more reducing power compared to the leaf extract. But, the phenolic content was higher in the leaf extract compared to the tuber extracts. However, both the extracts were comparably cytotoxic and showed broadspectrum antimicrobial activity. The antimicrobial compound in the tuber extract was nonpolar. The findings suggested that the ethyl acetate extracts of D. quercifolia may have active principles for the development of promising phytotherapeutics.

Published: April 2020

Identification of Labeo rohita, L. bata and L. gonius is sometimes problematic when usual morphological features are lost and it is difficult to differentiate them with traditional morphological features at their diverse developmental stages. PCR-sequencing provides an authentic alternative means of identification of individuals at species level. Three local carp fishes were collected and 16S rRNA genes were sequenced by sanger sequencing method after PCR amplification using universal primers. Obtained sequences were found accurate with blast search result which showed maximum range of similarity with the existing respective gene fragments present in GenBank database. Sequences were compared and multiple sequence alignment has revealed some polymorphic sites which can be used to differentiate these three species from one another. This study may provide valuable understanding to study their population in future.

Published: April 2020

A pot experiment with two acid sulfate soils of Badarkhali and Cheringa series were performed. After 18 years of fallow period in 2016, a crop trial was done in order to evaluate the response of rice plant without giving additional treatments. The average maximum temperature during the experimental period was 33.2ºC and average rainfall was 57 mm. Two cultivars of rice BRRI 48 and BRRI hybrid dhan 06 showed the tallest plant height of 115 cm and tillers 6.31 in numbers/plant on an average in both the soils. Panicle length was 16.5 cm, 1000-grain weight 22 g, grain yield 4.72 g/m2 and harvest index was 0.01 on average in both the soils. The experiment indicates that soil condition for crop growth possesses good quality after a long time and growth and yield parameters found satisfactory and significant (p ≤ 0.05).

Phytoavailability of chromium in chromium salt and poultry feed
Authors: Khan Tazeen Fatima , Roy Samapti , Rashid Md Harunur 
Published: April 2020

A pot-culture experiment was conducted to investigate phytoavailability of chromium in inorganic chromium salt and raw poultry feed made from tannery waste. Poultry feed from tannery waste was applied to the soil at a rate of 5 t/ha while inorganic chromium salt was applied at a rate of 10 mg/ kg and 810 mg/kg. An upland leafy-vegetable commonly known as Kalmi (Ipomoea aquatica) was used to assess the phytoavailability. Physico-chemical analyses of all soil and plant samples were done at 0, 15, 30 and 45 days of incubation to assess chromium phytoavailability and also its effects on the uptake of other heavy metals viz., lead and iron. Plants treated with Cr showed declined vegetative growth, low accumulation of dry matter, reduced nutrient concentration and reduced nutrient uptake. It was found that the plants accumulated higher amount of Cr from raw poultry feed treated soil compared to that of the inorganic Cr salt treated soil. The effect of treatments on Cr accumulation both in root and shoot was found significant. The study concludes that Cr is phytoavailable depending on the source and increased concentration of Cr decreases accumulation of Pb and Fe and thereby likely to decrease uptake of these metals.

Published: April 2020

Bagarius bagarius (Hamilton, 1822), a freshwater catfish species, is important as food and game fish in Bangladesh, Bhutan, India and Nepal. In Bangladesh, it is known as Baghair and has been enlisted as critically endangered (CR) species in the IUCN Red List of Bangladesh 2000 and 2015, under the criteria A2cd version 3.1 mentioning declining trend in its population around 80% during the last 25 years (3 generation time). We studied the abundance of B. bagarius at 8 sites in three riverine habitats. We identified 8 individuals of B. bagarius from the Meghna river only (Shibpur site, Bhola Sadar). However, focus group discussion with fishers revealed that the species was frequently present in the catch from the river, although the abundance reduced considerably over the decade. We also found several other studies which reported the abundance of B. bagarius in different natural habitats. The findings from this study in combination with other published literature in the last 5 years indicated that the current status of B. bagarius in natural waters in Bangladesh do not fall below the threshold limits of CR species. Therefore, B. bagarius should be reclassified into a lower threatened status (but not Least Concern) than the current CR.

Published: April 2020

An incubation study was conducted to find out the best mixing ratio of acid and calcareous soil (maintaining 70% moisture) for pot experiment. Depending on various physico-chemical properties mixed soil 1 : 1 (i.e. acid : calcareous) was selected for pot experiment. The pot experiment was carried out to observe the effects of vermicompost and compost on soil properties and growth and yield of Kalmi (Ipomoea aquatica Forsk.). This experiment included seven treatments with three replications including control. Treatment variables were T0 (control), T1 (4 t/ha vermicompost), T2 (8 t/ha vermicompost), T3 (12 t/ha vermicompost), T4 (4 t/ha compost), T5 (8 t/ha compost) and T6 (12 t/ha compost). All the treatments had significant positive effects over control on growth and yield of kalmi. The highest growth and yield were recorded with T3 (12 t/ha vermicompost) treatment. In case of, macro and micronutrient uptake treatment T3 (12 t/ha vermicompost) performed best followed by T6 (12 t/ha compost) over T0 (control). However, in post-harvest soil except soil reaction (pH); electrical conductivity (EC), organic carbon (OC), available N, P, K, S, Ca, Mg, Na, Fe and Zn significantly increased for T3 (12 t ha-1 vermicompost) than T1, T2, T4, T5, T6 and T0.

Authors: Ferdowshi Nafiza , Sultana Niger 
Published: April 2020

The purposes of the present study were to translate the Parenting Sense of Competence (PSOC) scale and to determine its initial psychometric properties. Three hundred mothers were selected as participants from Dhaka city who have children aged 6 to 10 years. Collected data were analyzed to determine psychometrics by using Cronbach alpha, Spearman-Brown’s split-half and exploratory factor analysis. Results showed that internal consistencies were: Cronbach α = 0.663 and split-half reliability r = 0.636. As both internal consistencies value were quite similar that would make PSOC scale’s reliability more supportive. Initially validity was conducted on pilot basis by measuring content validity and construct validity (r = 0.628, p < 0.01). Study limitations and further implications were also discussed.

Strukturna lega Habečkovega brezna (Idrijsko, Slovenija)
Authors: Čar Jože , Zagozda Bojana 
Published: April 2020

With detailed geological mapping at a scale 1:5 000, beside general geological data also the structural and tectonical circumstances of the surrounding of Habečkovo brezno were recognised. The complicated tension deformations developed in compressive condition and the thrust contact are the main reasons for development of hydrological and surface karst features. With kinematical reconstruction we recognised that 400 m deep Habečkovo brezno has a special structural and hydrological location. S podrobnim geološkim kartiranjem smo poleg splošnih geoloških podatkov rekonstruirali tudi strukturne in tektonske razmere. Pri tem smo ugotovili zapletene natezne deformacije, ki jih sicer na prvi pogled ni mogoče razložiti v splošnih tlačnih pogojih. Prav natezne deformacije predstavljajo poleg narivnega kontakta bistveno osnovo za razvoj hidroloških razmer in površinske kraške morfologije obravnavanega terena. Z rekonstrukcijo kinematskega razvoja ozemlja smo ugotovili, da ima 400 m globoko Habečkovo brezno izjemen strukturni in hidrološki položaj.
