Three types of packages containing enough sanitary supplies for one menstrual period were weighed and distributed to 100 subjects to determine adequacy of supplies and compliance to protocol. Returned packages were then reweighed to determine total menstrual loss. No subject used all the supplies in her package; therefore, packages contents were deemed ample. 7 subjects added their own purchased products to their packages; since added products were specified by name, weight corrections were easily made. 2 subjects lost unused supplies which were specified, and weight corrections were made accordingly. Evaporative loss from sealed and stored and frequently opened packages was measured. 100 g distilled water were added to contents inside 60 packages which were sealed and set aside 7 days. Average loss from these packages was 0.65 +/- 0.57 g. 5 g water were added to 60 packages 4 times daily for 5 days (100 g total). Then packages were set aside for 2 days and weighed on day 7. Average loss from these packages was 1.25 +/- 0.85 g. The combination of storage plus frequent opening resulted in an average loss of 1.90 +/- 0.87 g. Thus, the direct-weight method permits recovery of 97-98% of sample.

The most significant research on inguinal hernia repair utilizing r-TAPP procedure includes follow-up periods of up to 2 years and examines approximately 150 cases. This article presents data from 434 consecutive r-TAPP procedures conducted on 324 patients, with follow-up ranging from a minimum of 3 years to 8 years.

Globally, agricultural lands are among the top emitters of greenhouse gases (GHGs), responsible for over 20% of total greenhouse gas (GHG) emissions. Climatic conditions, an acute challenge in sub-Saharan Africa (SSA), where access to mitigation technologies remains limited, have heavily influenced these lands. This study explores GHG contributions from crop production and their devastating and deteriorating impacts on the economy and environment and proposes a sustainable solution.

This study aimed to investigate the thermal plasma treatment of sewage sludge as an alternative waste management solution. Samples were collected from a sewage treatment facility in São Paulo, Brazil, and subjected to thermal treatments in a furnace at temperatures of 400, 600, 800, and 900 °C to assess moisture content, mass loss, and ash composition. Subsequently, the samples were processed in a thermal plasma reactor operating at an average power of 30 kW.
