An Entzia-dominated marsh-type agglutinated foraminiferal assemblage from a salt marsh in Tubli Bay, Bahrain
A salt-marsh assemblage of agglutinated foraminifera was recovered from a salt marsh on the east side of Tubli Bay in eastern Bahrain. This locality is one of the last remaining patches of salt marsh on the east coast of Tubli Bay. The salt marsh is covered by a single marsh plant species, Arthrocnemum macrostachyum. Samples were collected from beneath the Arthrocnemum canopy in two transects beginning at the maximum landward extent of halophytic plants in the high marsh and extending to a tidal channel at the seaward side of the low marsh. A distinct elevation-related zonation in foraminifera is observed from the high marsh to the low marsh. The trochamminids Entzia macrescens and Trochammina inflata are characteristic of the high marsh, whereas Ammonia, Elphidium, Peneroplis and smaller miliolids become common in the middle part of the marsh transect. The tidal channel at the lower limit of the marsh contains an assemblage dominated by Ammonia, Elphidium, adult specimens of Pen-eroplis, and smaller miliolids, with Clavulina and Agglutinella as the only agglutinated taxa. Living specimens of Entzia and Trochammina were observed during the winter 2019–2020 sampling season, whereas samples collect-ed in Autumn 2019 contained only dead specimens. One new species, ?Sigmoilina canisdementis sp. nov., is de-scribed herein. This is the first report of a live Entzia-dominated salt marshassemblage in the Arabian Gulf region
Profitability of Watermelon to Farmers in Ibarapa Central Local Government Area of Oyo State
The study analyzed the profitability of
watermelon as an alternative crop to the melon
the farmers in Ibarapa Central Local
Government Area of Oyo state, Nigeria are used
to grow traditionally. Unfortunately, melon had
remained a poor marketing commodity over a
long period of time due to price fluctuation.
Data collected were analyzed using descriptive
statistics and gross margin. Budgetary analysis
revealed a profitability of watermelon with gross
margin of ₦2.18 is realized for every ₦1 invest
on watermelon per hectare. The result of the
analysis also showed that total cost was
N3254250 and the total revenue was N7109600.
This gave a gross margin of N3855350 of
watermelon produced it therefore recommended
that the local government should acquire more
tractors for hiring to the farmers while subsidy
is required in other to reduce the cost of land
clearing. Finally, government should as a matter
of urgency make credit facilities and fertilizer
available to farmer, grade and open up more
road network that will facilitating easy
transportation of farm produce and reduce cost
of transportatio
Antimicrobial Susceptibility Pattern of Clinical Isolates of Escherichia coli and Proteus mirabilis Using Cefepime in Ogbomoso, Nigeria.
The challenge of Cefepime resistance in developing countries is substantial and likely to grow. Emergence of Cefepime-resistant bacteria has increased and managemen
Squatter settlements and slums and sustainable development
Squatter settlement is defined as a low residential
area, which has developed without legal right to the land or permission from the concerned authorities to build, and as a result, of their illegal status, infrastructure and services are usually inadequate (UN-Habitat 2003). On the other hand, slums are contiguous settlements where inhabitants are characterized by insecure residential status, inadequate access to safe water, inadequate access to sanitation and other basic infrastructure and
services, poor housing quality, and overcrowding (UN-Habitat 2003). Both are form of informal settlements that are not formally planned

Carbon Dioxide Utilisation -The Formate Route
UIDB/50006/2020 CEEC-Individual 2017 Program Contract.The relentless rise of atmospheric CO2 is causing large and unpredictable impacts on the Earth climate, due to the CO2 significant greenhouse effect, besides being responsible for the ocean acidification, with consequent huge impacts in our daily lives and in all forms of life. To stop spiral of destruction, we must actively reduce the CO2 emissions and develop new and more efficient “CO2 sinks”. We should be focused on the opportunities provided by exploiting this novel and huge carbon feedstock to produce de novo fuels and added-value compounds. The conversion of CO2 into formate offers key advantages for carbon recycling, and formate dehydrogenase (FDH) enzymes are at the centre of intense research, due to the “green” advantages the bioconversion can offer, namely substrate and product selectivity and specificity, in reactions run at ambient temperature and pressure and neutral pH. In this chapter, we describe the remarkable recent progress towards efficient and selective FDH-catalysed CO2 reduction to formate. We focus on the enzymes, discussing their structure and mechanism of action. Selected promising studies and successful proof of concepts of FDH-dependent CO2 reduction to formate and beyond are discussed, to highlight the power of FDHs and the challenges this CO2 bioconversion still faces.publishersversionpublishe
