The inadequate access to public water supply in Abuja has forced more than 80 % of the population of about 5 million to drill private borehole. Drillers are not aware of rock radioactivity especially Abuja granitic rocks which varies with depth. The radioactivity of 238U and 232Th decay chains for the lithological rock samples could be at equilibrium considering the age as well as the isotopic mass proportion which is assumed to be equal to its natural isotopic. A new approach of using Neutron Activation Analysis (NAA) is adopted for this study with the aim of minimizing sample size as well as less counting rate to estimate the concentration in rock samples. Subsequently, the epithermal method for the decay chain of 238U was also used for 40K decay chain determination. The result was used to determine the radium equivalent index risk on drillers with a value of 400.63 Bqkg‒1 which is higher than 370 Bqkg‒1recommeded by the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) by a factor of 1.08. This value of 400.63 Bqkg‒1 may pose hazard health risk on drillers with external hazard index of 1.1 which is higher than 1 recommended by UNSCEAR. The results of this analysis using NAA have indicated that the exposure level due to naturally occurring radionuclides was lower, but safety rules should be applied for the borehole drillers in Abuja and beyond.

Lean Manufacturing is a very powerful productivity improvement tool, and there are several manufacturing strategies that aid Lean. In this study, the Kanban System is examined. Kanban system is a manufacturing strategy used to achieve lean production with reduced cost and minimal inventory. This study seeks to identify the factors hindering Nigerian small and medium enterprises from implementing Kanban. The study was carried out using primary data, which was obtained from the survey method. Companies who participated in this study are SME's. From the result of this study, the following were identified; Top Management commitment, Vendor Participation, Inventory Management and quality improvement are important for Kanban deployment and towards Lean manufacturing.

Elaboration of profitable technology for processing of copper-zinc ores of Madneuli deposit is an important problem for Georgian economics. Typicality of mentioned problems is also lied in the fact that up to 40% of copper-zinc ore is mined and stored on the quarry walls, which hinders the further expansion of the quarry on the mining of main copper ore.
Because of t6he complexity of mineral composition of mentioned ore as wellas of the mutual coalescence of valuable components and similarity of the properties of copper and zinc minerals the flotation enrichment if the ores by preparation of the concentrates of separate metals is a very complex task whereas the preparation combined concentrate is possible without the essential losses of main components.
The conditions of flotation enrichment of copper-zinc ore of Madneuli deposit were selected and the corresponding concentrate was obtained.
The conditions of sulfatizing roasting and leaching of a cinder were determined allowing to exstract 90-95% of Cu; 85-99% of ZnSO4 in the form of corresponding sulfates.
The technological scheme of processing of copper-zinc ore with a preparation of the copper vitriol and brass ligature was elaborated.
It was established that the exstraction of gold and silver is possible from the residues by thiocarbamide method by high idexes : 95.9% and 82.4%, respectively.
As a result of processing of one ton of copper-zinc concentrate the preparation of 343 kg of copper vitriol and of 108 kg of 50 % of brass is possible at transparent extraction of Cu-98%, Zn-92% and 430kg of solid residue containing 7g (16.2g/t) of Au and 9g (20.9g/t) of Ag.

Radioactivity and major oxides investigations on lithological rock samples were studied using HPGe and XRF to understand the geological provenience on subsurface structures at Dei-Dei and Kubwa area of Abuja. The activity concentrations at Dei-Dei borehole varies from 18.5 � 1.7 to 37.1 � 3.6 Bq kg‒1, 44.6 � 4.1 to 97.4 � 8.1 Bq kg‒1 and 253.5 � 31.3 to 1195.6 �151.2 Bq kg‒1 for 238U, 232Th and 40K. Kubwa lithologic layers activity concentrations for 238U, 232Th and 40K ranges between 14.7 � 1.2 to 51.8 � 4.9 Bq kg‒, 32.5 � 4.1 to 85.3 � 8.1 Bq kg‒ and 118.9 � 15.7 to 751.2 � 93.9 Bq kg‒1. XRF results revealed that the increase in of 232Th activity decreases the activity of 238U in the presence of SiO2, CaO, Al2O3, Na2O, and K2O. This study provides useful information on the lithology radioactivity and for radiological mapping of the basement coastal pollution

This presentation will provide an overview of the principles and antecedents of supply chain resilience. The presenter will share the relevant empirical and practical insights into supply chain risk and resilience. In addition, the findings of research in supply chain resilience and innovation will be discussed, as well as best practices for improving resilience for the firms in process industries.Topics include: enterprise and supply chain risk and resilience management; key dimensions of resilience; disruptions- relicense relationship; resilience for large vs. small firms; best practices in relicense in the chemical industry.

Brazilian macaw palm is a typical abundant tree spread almost all over South America. Theirs fruits are a sort of small coco much appreciated particularly by kids, as its pulp is sweet and pleasant to chew. Even the amount of the natural production for this palm tree is quite impressive. These fruits can be entirely used for the noblest purposes, which are the manufacture of human food products. The pulp of macaw palm fruits are plenty of Vitamin A precursor and the inside nut has Omegas 3 and 6 oils. Both palm tree and fruit are locally named as �bocaiuva� and despite all scientific already proved knowledge, the usage of these palm trees was dramatically dropping in the past. In order to recover a cultural behavior, we started a project back in 2004 devoted to visiting small isolated communities in the Brazilian Pantanal wetland region, and teaching people how to prepare a dehydrated product from the pulp of these fruits that is similar to a regular flour. The responses received at that time exceeded our expectations, and we decided to carry on new similar projects. Today, there are concrete results to be mentioned: a few industries to process �bocaiuva� are already installed in the country and new ones are in process. The bocaiuva subject is currently largely explored at many universities and research centers. New potential applications are being constantly discovered in the area of food processing and products, cosmetics, animal feeding, and even pharmaceutical products. All these processes started from a complete sustainable project that aimed to rescue a vanishing cultural behavior, that would at the same time give opportunity for those involved to generated earnings simply by respecting the environment, as the bocaiuva fruits were to be collected in total balance with nature. These origins naturally required that the new companies arriving to commercially explore the macaw palm have a framework of environment protection at the very beginning, making the projects more environmentally friendly. Large areas of macaw palm are being planned, and some are already installed or in process of implementation, all in the state-of-art concept of crops consortium.
