Aspen Bibliography
Boreal forests receive nitrogen-(N)-enrichment via atmospheric deposition and industrial fertilization. While it is known that N-enrichment can intensify interactions with natural antagonists, it remains poorly understood how genetic variability in plant defense chemistry can affect biotic interactions and height growth in N-enriched environments. We grew replicates of five low- and high-tannin Populus tremula genotypes, respectively, under three N-treatments (ambient, 15, and 150 kg N ha−1 yr−1). We assessed shoot blight occurrence (i.e. symptoms caused by Venturia fungi) during four growing seasons, and tree height growth during the same period. Damage by Venturia spp. increased with N-addition during all years, likely …

Tanzania Journal of Science
Vegetation plays major roles in carbon storage and ecosystem functioning by modifying the rate of carbon fluxes thereby mitigating climate change. However, the focus of assessing the potentials for different vegetation on climate change mitigation has for so long been conducted outside cities, towns and municipalities. This study was conducted in Wilolesi and Ikonongo hills located in Iringa as representative of the Municipality forested hills in Tanzania to assess vegetation structure and their potential for climate change mitigation. Random sampling technique was employed to establish 20 rectangular plots of 20 m x 40 m (0.08 ha) in each hill to …

Tanzania Journal of Science
The effects of drying, packaging conditions and storage time on proximate composition of chia seeds were investigated. Chia seeds were dried at 63 °C for 30 min (low-temperature long time–LTLT) and at 75 °C for 30 s (high-temperature short time-HTST) using dry oven, air/vacuum-packed and stored for ten weeks. The effect of heat processing (drying) on chia seeds had significant difference (p < 0.05) in ash, fiber and fat contents while there was no significant difference (p > 0.05) in moisture and protein contents. Except for fiber content, there was no significant difference (p > 0.05) in moisture, ash, fat and protein of chia seeds dried at LTLT and HTST before storage. During storage time, there was …
Effects Of Plant Species Diversity And Biomass On Grazing Patch Selection By Semi Free-Ranging Cattle, Samora Andrew
Effects Of Plant Species Diversity And Biomass On Grazing Patch Selection By Semi Free-Ranging Cattle, Samora Andrew
Tanzania Journal of Science
Studies examining forage selection by large herbivores have generally focused on single herbivore-plant relationships and few studies link plant species diversity with large herbivore feeding preferences, particularly in species-rich ecosystems. A study was therefore conducted to examine how herbaceous plant biomass, species richness, diversity and evenness, together with elevation and distances to houses, agricultural fields and cattle holding-pen areas (kraals), predict cattle grazing intensity at small (0.5 x 0.5 m) and large (20 x 50 m) patches by semi free-ranging indigenous cattle in Kilombero Valley Floodplain wetland Tanzania. Results showed that cattle grazed patches with high species richness and intermediate …

Physicochemical And Sensory Evaluation Of Mixed Juices From Banana, Pineapple And Passion Fruits During Storage, Victor Matabura, Oscar Kibazohi
Tanzania Journal of Science
Juices from fresh fruits offer various health benefits, including strengthening the immune system and preventing diseases. Mixed fruit juices tend to have good nutritional contents and organoleptic properties like colour, flavour, taste, and overall appeal of different fruits. This work investigated the physicochemical and sensory attributes of fruit juice of low viscosity banana juice blended with pineapple and passion juices. The prepared juices were pasteurised at 92 °C for 15 s, bottled in air-tight glass bottles, and subsequently stored in two different conditions: an ambient temperature of approximately 28 ± 2 °C and a fridge at 4 ºC for one …
Corrosion Inhibition Of Mild Steel In Seawater By 2,4,6-Triamino-3-Pentadecylphenyl Acetate Derived From Cashew Nut Shell Liquid, Emanuel Ricky, Esther Lugwisha, Joseph Philip
Corrosion Inhibition Of Mild Steel In Seawater By 2,4,6-Triamino-3-Pentadecylphenyl Acetate Derived From Cashew Nut Shell Liquid, Emanuel Ricky, Esther Lugwisha, Joseph Philip
Tanzania Journal of Science
The corrosion inhibition performance of 2,4,6-triamino-3-pentadecylphenyl acetate on mild steel in seawater at stationary condition, 30 °C and pH 8 was investigated using potentiodynamic polarization and electrochemical impedance spectroscopy. The maximum inhibition efficiency of 93% was found in the presence of 300 ppm of 2,4,6-triamino-3-pentadecylphenyl acetate for both potentiodynamic polarization and electrochemical impedance spectroscopy techniques. The potentiodynamic polarization curves show that 2,4,6-triamino-3-pentadecylphenyl acetate acts as a mixed type inhibitor which influences more the anodic processes. The Nyquist plots revealed that the polarization resistance (Rp) increases whereas the double-layer capacitance (Cdl) and corrosion current density (icorr) decrease as the concentrations of …

Effectiveness Of Common Household Washing Of Tomatoes On The Removal Of Pesticide Residues, John Mahugija, Flaviana Ngabala, Faustin Ngassapa
Tanzania Journal of Science
The effectiveness of common household washing processes of tomatoes on the removal of pesticide residues was investigated in Iringa, Tanzania. Analyses of cleaned-up extracts were carried out using gas chromatography-mass spectrometry (GC-MS). Nine pesticide residues were detected in unwashed and washed samples. The compounds detected were chlorothalonil, pirimiphos-methyl, chlorpyrifos, profenofos, endosulfan sulphate, endosulfan ether, lambda cyhalothrin, cypermethrin and metalaxyl. The concentrations of chlorothalonil, pirimiphos-methyl, chlorpyrifos, profenofos, cypermethrin and lambda cyhalothrin in some unwashed and washed samples exceeded the maximum residue limits (MRLs). Washing reduced the concentrations of chlorothalonil and endosulfan sulphate in tomatoes by 22.2–98.0% (mean = 70%) and 33.3–55.6% …
