Honey plants are plants that produce a good amount of nectar and pollen that can be collected by bees to make honey. In the north of Côte d’Ivoire, beekeeping is an income-generating activity subject to climatic hazards. It is therefore necessary to study honey plants in the north of Côte d’Ivoire, which is an area of high honey production. The present study was carried out in the Ferme des Trois Lacs in the Department of Dabakala. The farm is one of the largest beekeeping farms in the North and the largest in the region. The study contributes to the knowledge of the honey plants of the Côte d’Ivoire and makes it possible to popularize beekeeping in the region. A total of 72 species of honey plants have been identified. They are divided into 66 genera and 29 botanical families. The richest family in species is the Fabaceae. These are more than half (55.5%) of the transition zone plants. The microphanerophyts are the most represented with 40.27%. The flora is dominated by shrubs at 33.72%. These plants mostly flower during the rainy seasons. Most are visited by bees for nectar. And finally, these plants are mostly spontaneous.

Biosynthesis of Eco-Friendly Silver Nano-Particles using Dry Fluted Pumpkin (Telfairia occidentalis) Leave Extract as Reducing Agent_Crimson Publishers

Biosynthesis of Eco-Friendly Silver Nano-Particles using Dry Fluted Pumpkin (Telfairia occidentalis) Leave Extract as Reducing Agent by Ihom P Aondona* in Crimson Publishers: Peer Reviewed Material Science Journals

The biosynthesis of eco-friendly silver nano-particles using dry fluted pumpkin (Telfairia ocidentalis) leave extract as reducing agent was carried out. The research used the extract which was prepared from dry fluted pumpkin leaves to reduce 0.01M silver nitrate solution without the addition of any capping agent. During the biosynthesis process qualitative measures like 15 minutes interval observation for 1hr., observation of precipitates formation, and laser light pointer were taken to establish the formation of AgNPs in the solution. The AgNPs for characterization were produced by allowing the biosynthesis solution to remain in the cardboard for 24 hours before filtering and drying the residue in the oven at 110 °C. The residue which was the AgNPs was characterized using ED-XRF and SEM. The NPs produced were of average size of 30nm and angular and cubicle in shape. The chemical composition of the NPs was 71.8% Ag2O, 25% SiO2, 2.18% Cl and other trace compounds. The NPs; given the eco-friendly method of their biosynthesis can be further purified to be used on wound bandage.

Mycenaean Archer from the Palace of Nestor 1300 BCE

"The authors interpret two joining pieces of a brightly colored wall painting found at the Palace of Nestor in 1939. The fragment, removed from the walls of the palace prior to its final destruction, represents part of an archer, probably female. Alternative rcconstructions are offered. Artistic methods and constituents of the plaster and paint are studied by XRD, PIXE-alpha analysis, XRF, SEM-EDS, PY/GC-MS, and GC-MS. Egyptian blue pigment was extensively employed. Egg was used as a binder for the pigments in a tempera, rather than a fresco, technique. The identification of individualized painting styles may make it possible to assign groups of wall paintings to particular artists or workshops." -taken from researchgate

GOLD TESTING MACHINE

The XRF Gold testing machine is a scientific instrument that employs X-rays to determine the purity of gold. X-ray analysis has been introduced by foreign organisations in India as part of the determining the purity in most efficient and quickest way. It's a precise, non-destructive method of determining the purity of gold and other metals. The X-Ray method of gold analysis provides a purity of gold of up to 10-12 microns, so it can penetrate to the extent and provide the purity result. In 20 seconds, this method will calculate the exact percentage of karat (of karat) in a solid piece of jewellery or any size or shape of a sample. It also calculates the element concentration of all forms of gold, white gold, platinum, silver, palladium, rhodium, and related alloys with pinpoint accuracy.

The chemical composition of many types of materials can be determined using Energy Dispersive X-Ray fluorescence (ED-XRF), which is a simple, precise, and cost-effective analytical tool. It is non-destructive and dependable, involves minimal sample preparation, and can be used for solid, liquid, or powdered samples. It can detect a wide variety of elements, from Chlorine (17) to Uranium (92), and has detection limits of over one part per million (PPM). Aside from the X-ray spectrometer, other older conventional approaches for testing gold purity include TouchStone and Acid. TouchStone and Acid, on the other hand, are toxic tests in which a small sample of gold is scratched and then analysed. In traditional fire assay method you will have to process the sample by melting it and then the long procedure of separation of elements, yields results after several hours. Not to mention the hazardous pollution it generates due to lead and acid usage in the process.

HOW DOES GOLD TESTING MACHINE OPERATE

Electronic or XRF based measuring machines are the most reliable and safe way to test gold. This accredited process can be used by both skilled appraisers and gold owners to determine the precise composition of their gold pieces. If you want to authenticate your gold coin or strip, you can use this exam. For your high-quality investments, you shouldn't have to worry about any possible inaccuracies or losses caused by the above gold testing methods. If you plan on checking gold products regularly, you should consider purchasing an automated gold testing system like Maxsell MXGT Aurum.

Genotype and Environment Interaction Determines the Yield Potential of a Crop under Changing Climate

Authored by Kwata Maphuti Georgina

Abstract

The physical characteristics and composition of dust material are essential in the study of soil contamination. The aim of the study is to determine the possible asbestos contamination in dust samples collected both outside and inside of homes villages that are close proximity to former asbestos mining areas. Asbestos is a silicate mineral that was mined in South Africa, but its mining was ceased in 2002 due to human health effects associated with inhalation. In January 2017 outside surface dust samples were collected in yards with a brush and plastic dust pan, sieved on site with 1.8 mm pore size stainless steel sieve to remove large particles and put into a labeled zipper plastic for storage. Trapped dust samples were collected on pieces of sticky tapes on hard surface both indoor and outdoor of homes and stored in sealed containers. The geochemical and morphological data were generated using (XRF) X-ray fluorescence and (SEM-EDS) Scanning Electron Microscopy - Energy Dispersive Spectrometry presented in the study is for January 2017. The samples were chemically treated and coated with carbonated before the analysis commenced. The main finding from this pilot study is that reported amphibole silicate asbestos mineral was detected at all the five sites. Previous studies have reported some of the dangers of inhaling asbestos fibres to include inflammation of the affected lung tissue, lung diseases and cancer of the lung tissue. Thus, its imperative that exposure to asbestos pollution should be eliminated or minimized.

Keywords: Surface dust; Trapped dust; Asbestos; Former mining areas; XRD, SED-EDS

Introduction

Mining of asbestos has left behind health and environmental problems [1]. Historically the asbestos materials were used for building roof, ceiling, and brake pads for vehicles [2]. While asbestos mining began little was unknown about the danger of the mineral due to the human and health effects [3]. Besides the banning of asbestos in 2002 is still contributing to the human health effects. Asbestos fibres mass is less 1 g which can be easily getting lifted in the air and suspended until transported to the close local communities [4]. There were cases of asbestos related diseases on the following mesothelioma, lung cancer and asbestosis which contributed to the high mortality due to the asbestos mineral "miracle mineral" [5]. The purpose of the study is to determine the geochemical and morphological composition from surface dust and trapped dust samples collected in the local communities in the vicinity to the derelict and abandoned mine dumps in Limpopo Province.

Experimental Procedure

Study Area

The study was undertaken within the following five local communities (Ga-Malemang Village, Ga-Mafefe - Mathabata Village, Penge and Taung Village) located in Limpopo Province (formerly Northern Province) in South Africa. Site B is fully rehabilitated and Sites A, C, D and E are partially rehabilitated. These communities are located near the old and abandoned asbestos mine dumps. The province has bushveld, majestic mountains, primeval indigenous forest, unspoilt wilderness and patchworks of farmland [6]. The geology of the province contains the Transvaal and Chuniespoort group; carbonate rock formation (contains iron and magnesium embedded in the rocks) form part of the dolomite series in succession near the top, which is followed by carbonate rock formation [7]. Most rocks in the province belong to the Malmani Subgroup and Penge formation. The most common rocks found in the province are shale, dolomite, chert, quartzite, conglomerate, breccia and diamictite [8]. Penge is an old town situated approximately 48 km north-west of Burgersfort, in the Greater Tubatse Local and Greater Sekhukhune District Municipalities. The asbestos mines were located south of the Pietersburg asbestos fields [9] and extend in an 80 km arc from Malisdrift in the north-west to the confluence of the Olifants and Steelpoort Rivers in the southeast[1] . The Penge asbestos mine and village are located in the southeastern extremities of the Pietersburg asbestos field [10]. Ga- Malemang village is situated in north-east of the province where the capital city of province is located on the road to Polokwane. The village is 30 km away from Polokwane and along the road there is smelter. Ga-Mafefe is situated in the north-west of the province where is the road to Burgersfort and Penge, Taung Village are 48 km away from Burgersfort town.

Sample Collection Method

Surface dust samples were collected using a brush, dust pan, sieved on site with 1.8 mm pore size stainless steel sieve to remove large particles and put into a labeled zipper plastic for storage. Trapped dust samples were collected using on pieces of sticky tapes on hard surface both indoor and outdoor of homes and stored in sealed containers.

Laboratory Procedure

Surface dust samples were analysed with the (XRF) X-ray fluorescence and trapped dust samples were analysed with the SEM-EDS (Scanning Electron Microscopy - Energy Dispersive Spectroscopy). The XRF is used to quantify the geochemical composition, while SEM-EDS are used to determine the physical or morphological features of the dust particles or fibres. Pieces of sticky tapes substrate containing trapped dust samples are mounted on specialised filter holders for SEM-EDS investigationsfollowed the method described by Atanasova[11]. All the specimens for SEM-EDS are coated with carbon to provide a conductive surface for optimum imaging. The XRF analysis major element analysis the milled sample (<75 |i fraction) was roasted at 1000C for at least 3.0g hours to oxidize Fe2+ and S and to determine the loss of ignition (L.O.I.). Glass disks were prepared by fusing 1.0 g roasted sample and 10 g flux consisting of 49.5% Li2B4O7, 49.5% LiBO2 and 0.50% Lil at 1150C. Quality control/Quality assurance was done by using an in-house amphibolites reference material (sample 12/76). Also 1.0 in every 10 samples is duplicated during sample preparation. For trace element analysis 12 g milled sample and 3.0 g Lico wax was mixed and pressed into a powder briquette by a hydraulic press with the applied pressure at 25 ton. The glass disks and wax pellets was analysed by a PAN Alytical wavelength dispersive Axios X-ray fluorescence spectrometer equipped with a 4 kW Rh tube [12].

Results and Discussion

The geochemistry results in (Table 1) shows the oxide of silicates of oxide silicon oxide (SiO2) ranged from 47.32 to 61.23 wt. %, aluminum (II) oxide (Al2O3) ranged from 7.7 to 12.86 wt.%, iron (II) oxide (Fe2O3) ranged from 10.02 to 31.91 wt.% and magnesium (II) oxide (MgO) ranged from 0.83 to 2.35 wt. %. These geochemical results only confirm the presence of silicates minerals. The asbestos mineral is one of the many silicate minerals that are suspected to still be present within the study area. (Figure 1) shows the amphibole [NaCa2 (Mg,Fe,Al)5O22(OH)2] mineral groups to be the most common asbestos mineral to be identified or present in all the five sites. The other silicate minerals detected were quartz [SiO2], kaolinite [Al2Si2O5(OH)], mica[KAI2(Si3Al010)(0H)2] and IIImenite [Fe2TiO3]. The non-silicate minerals detected were gibbsite[Al2(OH)3], calcite[CaCO3], Fe-oxide, organic, gypsum, lime, halite and clinochlore[Mg,Fe+5Al(Si3Al)O10(OH)8]. Previous studies by Moja [13]; [14,15] reported the amphibole asbestos mineral group being dominant in comparison to the and serpentine asbestos mineral group.

Conclusion

Since all the sites under investigation tested positive for the presence of the amphibole asbestos mineral group, it implies that the locals are continually being exposed to it. Urgent rehabilitation is recommended to reduce the health risks of these communities.
