Authors: Olowookere C. J. , Aladeniyi K. , Abu G. A. , Erimona J. 
Published: June 2022

In this study, radon concentration was measured with an active detector (RAD 7) in the Science Faculty building complex basement of a tertiary institution in South West (SW), Nigeria. The attendant risk descriptors were determined with the help of mathematical models. The range of mean detectable radon concentration in the basement is 26.5 ±12.3 – 242 ± 50.7 Bq m-3 and the mean for all the rooms examined is 61.74 ± 58.48 Bq m-3. The overall mean is less than the global mean of 100 Bq m-3. The mean annual dose rate is found to be 0.97 ± 0.92 mSv y-1. The mean annual effective doses for different subjects examined are 0.412 ± 0.391 mSv y-1 (worker), 0.0221 ± 0.0209 mSv y-1 (student in lab session), 0.515 ± 0.488 mSv y-1 (student who lives in the hostel) and 2.149 ± 2.036 mSv y-1 (home owner). Students and workers in the basement are not likely to develop serious health effects, however, if the basement is used as a living room, the radon concentration in Room I-R might lead to health effects. The range of calculated excess life cancer risks (ELCRs) are (0.64-5.82) x 10-3 and (1.16 -10.58) x 10-3 for student and homeowner respectively. The mean values for the two subjects examined fall below the maximum risk of 3.5 x 10-3.

Authors: Mugabi Robert , Byakika Stellah , Mukisa Ivan Muzira 
Published: June 2022

The effects moisture content, temperature and soybean ratio on expanded product characteristics of extruded maize-soybean blends were studied. Response surface methodology was used to study the effects of extrusion conditions on extrudate properties taking barrel temperature (BT), feed moisture content (FM) and soybean flour ratio (SR) as factors. Expansion ratio (ER), water absorption index (WAI), water solubility index (WSI), hardness and colour (b* - (+) yellowness) of the extrudates were determined. BT and FM had significant effects on ER (p < 0.05). At low FM levels, ER increased with BT. It was observed that both FM and BT significantly affected WAI and WSI. WAI increased as FM increased. Increasing FM to 20% resulted in a decrease in WSI, beyond which an increase was observed. Hardness increased significantly as feed moisture content increased. High SR content significantly increased the extrudate hardness. FM had no significant effect on colour. Colour increased as the SR and BT increased. Significant regression models explained the effects of SR, FM, and BT on all response variables. All of the response variables' R2, were higher than 0.89.

Authors: Rogers Peter M. , Yanda Pius Z. , Pauline Noah M. , Haikola Simon , Hansson Anders , Fridahl Mathias 
Published: June 2022

The world’s agricultural production is declining due to severe loss of soil fertility through natural processes or because of human activities. Biochar has been identified as a potential soil amendment to regain its fertility and increase crop productivity. This study aimed to assess the effects of biochar on soil nutrients and crop yields in the southern highlands of Tanzania. Data were collected through key informant and household interviews, and from sampling of soils in coffee farms where biochar of maize cobs origin was incorporated at the rate of 3 t ha-1. Purposive sampling approach was deployed to identify the villages in which farmers have been incorporating biochar in farms. A total of 172 households, 30 key informants, and 12 top and subsoil samples were involved in this study. Quantitative data were analyzed using SPSS version 20, and excel spreadsheet was used for descriptive results and relationships. The findings revealed that biochar significantly increased soil pH, iron (Fe), organic carbon (OC), cation exchange capacity (CEC) and exchangeable bases (potassium-K, magnesium-Mg). T - tests showed significant increase of soil nutrients in biochar treated soils. In addition, biochar increased coffee and maize yields from 1 t ha-1 to 3 t ha-1.

Comparison on Vegetation Composition and Structure in Fire Prone Forest of Ilunde and Fire Suppressed Forest of Kitwe in Tanzania
Authors: Mganga Nyatwere D 
Published: June 2022

Fire is among the factors influencing survival and development of plants in ecosystems. This study was conducted in frequently burnt and fire suppressed miombo woodlands of Ilunde and Kitwe, respectively. Tree stem density, basal area and composition of plants were determined. The methods used involved recording the numbers of tree stems, diameter at breast height and classifying vegetation to species level. In Kitwe forest, mean stem density of 582.7 ± 52.90 stems ha– was higher than 356.8 ± 38.98 stems ha– which was recorded in Ilunde forest (t = 15.98, df = 29, p < 0.05). Similarly, a higher mean tree basal area of 16.14 ± 1.32 m2 ha– was recorded in Kitwe forest, while 8.54 ± 0.94 m2 ha– being recorded in Ilunde forest (t = 3.34, df = 14, p < 0.05). Czekanowski’s similarity coefficients for trees, shrubs and saplings, and herbs and grasses were 0.46, 0.34 and 0.22, respectively. Fire adapted species were recorded in Ilunde forest. Fire prone miombo woodland had lower tree stem density, basal area and dominated by fire adapted species. Similarity coefficient between the two forests was also low. Prescribed burning is recommended in miombo woodlands for sustainable species composition and tree structure.

Totalitarismo, fascismo y su importancia para América Latina: continuidad de la Guerra Fría en el campo cultural y las ciencias sociales
Authors: Urrego Ardila Miguel Ángel 
Published: June 2022

Varios estudiosos de la historia mundial insisten en defender el argumento del fin de la Guerra Fría a raíz de la desintegración de la Unión Soviética. Otros hablan de una “nueva” guerra debido a las recientes diferencias entre Estados Unidos y China. A nuestro juicio, y especialmente en plano cultural y de la producción de saber en las ciencias sociales, la Guerra Fría no ha culminado y, por el contrario, asistimos a un rejuvenecimiento de las tesis expuestas en los años cincuenta y sesenta del siglo pasado y que se caracterizan por un anticomunismo visceral y una legitimación de la política imperial, especialmente de Estados Unidos, hecho evidente, por ejemplo, en las interpretaciones sobre el reciente ascenso de partidos de extrema derecha y el actual conflicto entre Ucrania y Rusia. Por otra parte, el neoliberalismo ha restablecido el rasgo fascista del capitalismo y asistimos a una guerra contra la sociedad y en particular contra los sectores marginados. Por ello creemos pertinente detenernos en el examen de dos categorías que son urgentes debatir nuevamente: fascismo y totalitarismo, y especialmente sobre las posibilidades su empleo en América Latina y la importancia de rescatar las enseñanzas de la lucha antifascista para entender el momento presente.

Abstract. Organic aerosol (OA) has a significant contribution to cloud formation and hence climate change. However, high uncertainties still exist in its
impact on global climate, owing to the varying physical properties affected by the complex formation and aging processes. In this study, the
hygroscopicity, volatility, cloud condensation nuclei (CCN) activity, and chemical composition of particles were measured using a series of online
instruments at a rural site in the Pearl River Delta (PRD) region of China in fall 2019. During the campaign, the average hygroscopicity of OA
(κOA) increased from 0.058 at 30 nm to 0.09 at 200 nm, suggesting a higher oxidation state of OA at larger particle
sizes, supported by a higher fraction of extremely low volatility OA (ELVOA) for larger size particles. Significantly different diurnal patterns of
κOA were observed between Aitken mode particles and accumulation mode particles. For Aitken mode particles (30–100 nm), the
κOA values showed daily minima (0.02–0.07) during daytime, while the accumulation mode exhibited a daytime peak
(∼ 0.09). Coincidently, a daytime peak was observed for both aged biomass burning organic aerosol (aBBOA) and less oxygenated organic aerosol
(LOOA) based on source apportionment, which was attributed to the aging processes and gas–particle partitioning through photochemical reactions. In
addition, the fraction of semi-volatile OA (SVOA) was higher at all measured sizes during daytime than during nighttime. These results indicate that
the formation of secondary OA (SOA) through gas–particle partitioning can generally occur at all diameters, while the aging processes of
pre-existing particles are more dominated in the accumulation mode. Furthermore, we found that applying a fixed κOA value (0.1) could
lead to an overestimation of the CCN number concentration (NCCN) up to 12 %–19 % at 0.1 %–0.7 % supersaturation (SS),
which was more obvious at higher SS during daytime. Better prediction of NCCN could be achieved by using size-resolved diurnal
κOA, which indicates that the size dependence and diurnal variations in κOA can strongly affect the NCCN at
different SS values. Our results highlight the need for accurately evaluating the atmospheric evolution of OA at different size ranges and their impact on
the physicochemical properties and hence climate effects.
