Abstract: Adsorption is one of the most easy-to-operate, less costly, efficient and, most importantly, environmentally
friendly methods of removing toxic metals from aqueous environments. We used spent Impra Green Tea
Ginseng Flavoured to recover mercury (Hg2+), lead (Pb2+) and cadmium (Cd2+) in binary and ternary
systems from greywater. We undertook this study in binary and ternary systems at adsorbent dosages
with a corresponding 100 mL varied initial metal concentrations of the greywater. The adsorption efficiency
at varied concentrations and dosages in the binary systems by the spent tea waste ranged from 38.5%
to 100% for lead, 11.50% to 100% for cadmium and was 100% for mercury. In the ternary system, the
adsorption efficiency of toxic metals ranged from 28.91% to 72.85% for cadmium and was 100% for
mercury and lead. The maximum adsorption capacity (Qe
) for toxic metals in the binary system ranged
from 38.46 to 81.97 mg/g for Pb2+ and 12.64 to 56.82 mg/g for Cd2+. The Langmuir adsorption isotherm
model was the best fit for the adsorption of toxic metals by Impra Green Tea Ginseng Flavoured. The pH
under which the experiments were conducted showed very high removal efficiency for lead and mercury
but lower removal efficiencies for cadmium. Spent Impra Green Tea Ginseng Flavoured can be used as an
effective and low-cost adsorbent of toxic metals from greywater or wastewater. Based on our findings,
further studies should be conducted to determine the effects of varying the contact time, temperature and
elevated metal concentrations in the greywater or other wastewater2023-01-01T00:00:00ZAUDIENCE LISTENERSHIP OF FM RADIO: A CASE STUDY OF RURAL DEVELOPMENT IN NORTHERN GHANAAntwi-Boateng, O.Musa, M.

Abstract: The quest for effective strategies for rural development continues to be
a challenge for policymakers in sub-Saharan Africa and their development partners.
Communication development strategies executed using FM stations have emerged
as a promising tool as a result of the medium being the most popular source of
information among rural dwellers in the region. Thus, this research explores the
efficacy of FM radio in rural development by examining the listening patterns of
residents and the benefits of such listenership to the lives of inhabitants of the
Tamale metropolitan area. This is achieved via a quantitative analysis of surveys of
about 400 residents of the Tamale metropolis. The study rejects the perception that
FM radio programs in Ghana are mostly entertainment driven and are purveyors of
light news. By putting searchlight on the motivations of radio listeners, the study
finds that FM radio is the most reliable and trusted source of development infor
mation because of the ease, convenience and low cost of listening for listeners, and
because programming is mostly in local languages. The study establishes that FM
radio is the main source of information on agriculture, education and health in rural
communities thereby contributing to rural development. Listeners’ participations in
radio phone-in programs were highly rated for fostering audience motivation and
agency. However, some challenges emerged. Listenership of FM stations was dis
proportionately male; there were complaints that radio programs were too “urban”;
programming lacked innovation; and the timing of programs was poor. Based on
these findings, the study recommends that FM radio stations should employ media professionals to conduct effective audience analysis to gain a grounded under
standing of audience radio use if they are to develop the right programming timing
to reach a greater audience of rural residents.2023-01-01T00:00:00ZANTHRACNOSE DISEASE OF MANGO: EPIDEMIOLOGY, IMPACT AND MANAGEMENT OPTIONSKankam, F.Larbi-Koranteng, S.Adomako, J.Kwodaga, J.

Abstract: Mango is one of the frequently cultivated seasonal fruit crops in several tropical and
subtropical regions. It is consumed as whole fruits apart from serving as raw materials
for most industries that are into mineral production. Mango production is, however,
constrained by diseases, pests, and poor post-harvest handling of fruits. Anthracnose
disease, caused by Colletotrichum gloeosporioides Penz and Sacc, is one of the most
important yields limiting constraint in mango production across the globe. The disease
occurs in both the field and post-harvesting. In the field, it affects aboveground parts,
such as the stem, branches, leaves, flowers, and fruits. Anthracnose disease reduces the
shelve life and marketability of mango fruit. In Ghana, anthracnose disease is respon
sible for about 30% yield/fruit loss. Most farmers do not control it, although some have
resorted to the application of various fungicides not registered for mango anthracnose
disease management in Ghana. This chapter will highlight on the importance of the
disease on the mango industry in Ghana, control strategies currently employed thereby
reducing the over-reliance on chemical control option and propose ways to minimize
the effect of the disease in the country2022-01-01T00:00:00ZALTERNATIVE GREEN AND NOVEL POSTHARVEST TREATMENTS FOR MINIMALLY PROCESSED FRUITS AND VEGETABLESOsei-Kwarteng, M.. Mahunu, G.

Abstract: Minimally processed fresh produce is ready to eat and subjected to minimal tech
nology before consumption. Fresh fruits and vegetables (FFVs) are minimally pro
cessed commodities that are metabolically active and undergo physiological processes
such as ripening and senescence, reducing their quality and shelf life. Postharvest
technologies maintain the quality and prolong the shelf life of harvested produce,
without which the quality deteriorates such that significant economic loss ensues due
to water and nutrients loss, physiological deterioration, biochemical changes, and
microbial degeneration. Conventional postharvest treatments such as temperature
management, and chemical and gaseous treatments are widely known for control
ling postharvest issues in FFVs. However, there are novel and green alternative safe
methods that are employed to maintain the postharvest quality and prolong the
shelf life of FFVs. This chapter focuses on seven common alternative novel and green
postharvest treatments: nitric oxide, ozone, methyl jasmonate, salicylic acid, oxalic
acid, calcium, and heat treatments. These treatments are explained and some of their
current application on FFVs are discussed and tabularized indicating the optimum
treatment conditions reported in the latest scientific publications.2023-06-01T00:00:00Z
