  • Growth and leaf epidermal response of three Sesamum indicum varieties to
           industrial effluent irrigation

    • Authors: AA Abdul Rahaman, OM Olaniran, FA Oladele
      Pages: 1 - 6
      Abstract: The effect of industrial effluents was studied with respect to growth and leaf anatomy of three Sesamum indicum varieties (NGB 00931, NGB 00937 and NGB 00939). Industrial effluents (25%, 50%, 75% and 100%) from two industries are used to irrigate the plants. Although, the control plants possessed larger leaves and longer stems than the effluent-treated plants, at lower concentration, the plant growth is relatively higher. Gradual decrease in the germination of seeds and seedling growth with increase in effluent concentration was observed. The best germination and seedling growth was observed at the 25% concentration. Leaf epidermal features (stomatal density, stomatal index, stomatal size, trichome density, tricome index, trichome size and number of epidermal cells) are more influenced in the effluent-treated plants than in the control plants from the Peace Standard Pharmaceutical Industry than in the effluent from the Global Soap & Detergent Industry. Thus the industrial effluents can be safely used for irrigation purposes with proper treatment and dilution at 25%.Bangladesh J. Sci. Ind. Res. 52(1), 1-6, 2017

  • Palynological characterization of honey samples from Kwara State, Nigeria

    • Authors: SD Oyeyemi, J Kayode
      Pages: 7 - 14
      Abstract: Palynological analysis of honey samples from different localities in Kwara State, Nigeria was carried out to isolate and identified pollen types in the honey samples. Out of forty two pollen types belonging to twenty two botanical families recovered, twenty five were identified to species level, eight to genus level and eight to family level. A total of 849,978 pollen grains were counted with 46,355 in Shao, 101,356 in Ganmo, 22,000 in Idofian, 28,337 in Omupo, 200,090 in Iludun Oro, 298,079 in Ijagbo, 22,100 in Offa I and 131,142 in Afon. The major pollen occurrences in the honey samples include those of Sarcocephaluslatifolius, Parkiabiglobosa, Phyllantusdiscoideus, Tridaxprocubens, Combretaceae/Melastomataceae, Spondiasmombins and Hymenocardiaacida. Other important honey plants identified are Elaeisguineensis, Lanneasp, Parinarisp, Celtissp and Entadaabssynica. All these are characteristic plant taxa of the Forest-Savanna ecotype of the studied area. The presence of relatively high quantity of pollen shows their richness in pollen composition and also a clear evidence that the honey are from botanical sourceand also multifloral.Bangladesh J. Sci.

  • Biodiesel from non-edible Karanja seed oil

    • Authors: MJ Alam, SMS Rana, MA Haque, M Hossain, SMA Sujan, MS Jamal
      Pages: 15 - 20
      Abstract: The fossil fuel resources are dwindling day by day. Fuel has been a challenge for today’s scientific works for increasing demand. The methyl esters of vegetable oils, known as biodiesel are becoming increasingly well known because of their low environmental impact. Methyl esters of Pongamiapinnata are derived through esterification and transesterification. Several processes of biodiesel fuel production has been developed, among which transesterification using alkali as a catalyst gives high level of conversion of triglycerides to their corresponding methyl ester in a short duration. Amount of solvent, catalyst, temperature and reaction time were optimizedfor estimates the conversion efficiency. The physical properties of Karanja seed oil (KSO) and biodiesel were studied and compared with standard. FTIR and TGA spectrums of KSO and KSO Biodiesel were studied for the confirmation of conversion.Bangladesh J. Sci. Ind. Res. 52(1), 15-20, 2017

  • Nature of errors in percentage syllable articulation as an effect of
           reverberation time on Bangla

    • Authors: SMN Imam, D Takahashi
      Pages: 21 - 30
      Abstract: This paper identifies the nature of errors in the Percentage Syllable Articulation (PSA) test for Bangla, as a continuation and extension of a study conducted and published by the authors to determine the effects of Reverberation Time (RT) on Bangla. Errors due to RT 2.0 s are enumerated to derive Percent Error (PE) at initial, medial and final positions of phonemes in syllables, for both vowels and consonants. It is found that consonants are more vulnerable to errors than vowels, as their mean PEs are 37.8% and 27.6% respectively. Relative positions of phonemes in syllables have significant effect on PE.  For vowels, mean PE increases from 12.1% to 56.7% for their medial and medial plus final positions respectively. For consonants, mean PE rises from 17.1% to 67.8% for their initial and final positions. Variations in PE within same groups of vowels and consonants, exemplify unique inherent characteristics of each phoneme.Bangladesh J. Sci. Ind. Res. 52(1), 21-30, 2017

  • Color removal from textile wastewater using date seeds activated carbon

    • Authors: MA Rahman, T Ahmed, IN Salehin, MD Hossain
      Pages: 31 - 42
      Abstract: Powdered Activated carbon (PAC) developed from date seeds was used as an adsorbent for the removal of color from textile wastewater. Batch adsorption experiments were performed in the laboratory with varying process parameters (temperature, pH, agitation, adsorbent dosage, particle size) over a range of contact periods and wastewater pollutant (color) levels. It was found that the removal mechanism could be better characterized by the Freundlich adsorption isotherm model compared to the Langmuir model. Also, The Lagergren's pseudo 2nd order kinetic model fitted relatively well ( = 0.99) over the selected range of contact times (5-60 minutes) and initial color concentrations (800-1200 Pt-Co unit) compared to the pseudo-first order model indicating that chemisorption may be playing a dominant role in the adsorption process. Both external film and intra-particle pore diffusion mechanism were involved in the adsorption process but film diffusion was found to be rate limiting. While analyzing the thermodynamics, the negative value of free energy (-1.83 to -3.4 KJ/mole), positive value of enthalpy (0.26 to 0.28 KJ/mole) and entropy (0.97 to 1.01 J/K/Mole) associated with the color removal mechanism indicated that adsorption was spontaneous and endothermic with increased disorder and randomness at the solid-liquid interface of the date seeds PAC. These experiments suggests that date seeds PAC is a very effective adsorbent, capable of removing a significant amount of color from industrial wastewater if process variables can be optimized and can be explored as a potential low-cost alternative to expensive tertiary treatment options.Bangladesh J.

           evaluation as cosmetic ingredient

    • Authors: MK Nahar, SA Lisa, K Nada, M Begum
      Pages: 43 - 48
      Abstract: The physicochemical properties, fatty acid composition, aflatoxin contamination and heavy metals of extracted mango kernel oils of four Bangladeshi varieties (Langra, Gopalbhog, Khirshapat & Amrupaly) were studied. The results were compared with published values of ‘CIR expert panel’, ‘Indian Standard of Mango Kernel Fat’, ‘Scientific Commission of the European Community’ and ‘US Food and Drug Administration (FDA)’. The estimated values of aflatoxin B1and total aflatoxins were 1.45809 ppb and 5.14761ppb respectively which were lower than the limit levels of ‘European Community (2 ppb for aflatoxin B1)’ and ‘US FDA (20ppb for total aflatoxins value)’. Heavy metals like arsenic & lead concentration were found 0.034 & 0.45 ppm respectively which were lower than the value of ‘Indian Standard of Mango Kernel Fat; 9231 (1979)’ (0.5 & 5.0 ppm respectively). In fatty acid composition; palmitic acid, stearic acid, arachidic acid, oleic acid and linoleic acid were within the range of ‘CIR expert panel’ reported values.Bangladesh J. Sci. Ind.

  • Heavy metal assessment of polluted soil around Hatirjheel Lake of Dhaka
           city, Bangladesh

    • Authors: MA Hashem, MS Nur-A-Tomal, MJ Abedin, SA Bushra
      Pages: 61 - 66
      Abstract: Heavy metals contamination in soil is a big issue to the environment because of its potential risk to the ecosystem and human health. Industrialization increases the disposal of industrial wastes containing heavy metals. Most industries are located near the bank of rivers or Lakes where industries can dump their effluents without proper treatment. In this study, an investigation was carried out to evaluate the heavy metals of the contaminated soil near HatirjheelLake of Dhaka city, Bangladesh. The collected soil samples were air-dried, acid digested and aliquots were analyzed by the atomic absorption spectroscopy for the quantification of heavy metals. The ranges of heavy metals were found in soil: arsenic 2.7–33.3 mg/kg, lead 9.5–74.9 mg/kg, chromium 21.8–43.1 mg/kg, manganese 138.3–222.7 mg/kg and iron 159032.9–246382.8 mg/kg, respectively. Cadmium was below the detection limit. The dominance of heavy metals series in the soil follows: Fe >Mn> Cr >Pb> As > Cd. Heavy metals content in the soil by comparison with the USEPA guidelines show that Pb was non-polluted; Cr and Mn were moderately polluted; As and Fe were heavily polluted in the study area. Heavy metals accumulation in the soil could pose a potential risk to the ecosystem as well as to human health.Bangladesh J. Sci. Ind. Res. 52(1), 61-66, 2017

  • Pesticidal effect of different botanicals and wood ash against Angoumois
           grain moth Sitotroga cerealella Olivier.

    • Authors: Tahmina Akter, Ruhul Amin
      Pages: 67 - 72
      Abstract: Pesticidal effects of different botanicals (like neem, Azadirachta indica; Biskataly, Polygonum hydropiper Linn. karanja, Pongamia pinnata, arjun (Terminalia arjuna ) and tobacco, Nicotina  tabacum ) and wood ash were studied for the management of Angoumois grain moth, Sitotroga cerealella (Olivier) in stored rice grain at the Department of Entomology, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh. For the studies, de-infested rice variety BR-11 was collected from farm store house. The treatments of the studies were: Neem leaf powder @ 10gm / kg of rice grains were mixed with seeds (T1); Biskatali leaf powder @ 10gm/kg of rice grains were mixed with seeds (T2); Karanja leaf powder @ 10gm / kg of rice grains were mixed with seeds (T3); Arjun leaf powder t @ 10gm / kg of rice grains were mixed with seeds (T4);  Tobacco leaf powder @ 10gm / kg of rice grains were mixed with seeds (T5); Wood ash @ 10gm / kg of rice grains were mixed with seeds (T6) and Control (T7) and experiment was laid out in a Completely Randomized Design (CRD) with four replications. In all generation (1st, 2nd and 3rd generation), the results showed that different botanicals and wood ash had pesticidal effect against angoumois grain moth. Among them tobacco leaf powder showed the highest toxic effect in case of the percent of mortality (100%), percent of adult emerged (0.00%), adult longevity (0.00) and repellency effect (75%) which closely followed by neem leaf powder (T1), whereas biskataly and karanja leaves powder showed lowest and the no repellency rate (0.00) was recorded in T3 and T6 treatment.Bangladesh J.
