A note on weak convergence of mean residual life of stationary mixing random variables

AbstractFor a sequence of strictly stationary uniform or strong mixing we estimate the mean residual time of the marginal distribution from the first n observations. Under appropriate conditions it is shown that the estimate converges weakly to a well-defined Gaussian process even when the sample size is random

Parametric investigation of fixed-tray, semi-continuous distillation column for ethanol separation from water

This work was aimed to evaluate the parameters affecting the separation of model fermentation broth (7 mole% ethanol) using 10-tray, semi-continuous distillation column. Ethanol compositions in distillate and bottoms were determined at different reflux ratios and feed locations. Results show that the distillation of lower ethanol concentration is better carried out at higher reflux ratio with feed charged at the middle or bottom tray for good overall tray efficiency. The distillation unit is able to purify the feed to 78 mole% ethanol in distillate. Through trial-and-error stepping off, about 81 mole% was predicted as optimum ethanol purity at reflux ratio of 2.33, while a lower reflux ratio of 1.44 was estimated for 78 mole%. Fixed-tray, semi-continuous distillation is a suitable option to concentrate fermentation broth with sufficient ethanol purity

Collaborative Strategy in Corruption Prevention and Enforcement in Indonesia

Corruption, as an extraordinary crime, cannot be eradicated by a single party alone. Presidential Regulation No. 54 of 2018 concerning the National Strategy for Prevention of Corruption (Stranas-PK), is an integrated effort by the government to combat corruption in Indonesia. This study is descriptive, using literature to determine how the implementation of Stranas-PK is viewed from the perspective of collaborative governance, using the theory proposed by Emerson & Nabatchi (2015). The results of the analysis show that the implementation of the National Strategy-PK has begun to demonstrate the existence of collaborative governance in some action implementations. However, based on the National Secretariat-PK report and findings from several studies, several obstacles that need to be addressed have been identified. These include: (1) The adjustment of the legal framework, (2) The fulfillment of quality and capacity of resources, (3) The establishment of a model for civil society participation, (4) Increased involvement of non-government actors, (5) Enhanced engagement of K/L/PD (ministries, institutions, and regional governments), and (6) The measurement of the impact of implementation.

Aflatoxin Total and Microbial Contamination of Grains, Oil Seeds, Yam Chips and Fish Sold in Maiduguri Market

Aflatoxins are secondary metabolites of fungus Aspergillus flavus and closely related species that infects severalagricultural commodities. The consumption of contaminated commodities adversely affects the health of humansand animals and also a cause of significant economic losses to producers. This study surveyed the aflatoxincontamination level of cowpea, maize, melon, groundnut, yam chips and fish sold in Maiduguri metropolis.Samples from each product (250 g) were bulked and thoroughly mixed using coning and quartering method to geta representative sample for analysis. Laboratory observations were carried out regarding microbial analysis,proximate composition and aflatoxin content. Samples for aflatoxin detection were classified into three; unsortedsamples, sorted samples and sorted/washed dried samples. Fish had the highest bacterial load 2.48 x 106 cfu/ml andAspergillus species were found to be the predominant fungi identified. Maize and groundnut with moisture contentof 5.63 and 5.62 had the highest total aflatoxin contamination (320.51 μg/kg and 236.3 μg/kg respectively) both inthe unsorted group. Total aflatoxin reduction of (58.82 - 99.99%) was observed in all the sorted samples andsorted/washed dried samples. It can be concluded that commonly sold food in Maiduguri had fungal and Aflatoxincontamination. Food should undergo several rounds of sorting to remove discoloured grains and grains that showsevidence(s) of deterioration to reduce the ingestion of food contaminated with aflatoxin
