Mondia whitei (omulondo) is one of the most consumed herbs in and around Kampala city, this is attributed to its many uses such as enhancing of cerebral and peripheral blood circulation, treatment for anorexia, treatment of sexually transmitted diseases, stomach ailments and impotence, treatment of hypertension and many others. Currently, the root is processed into other products like; mulondo liqueur and mulondo powder. However, the processes (washing and smashing/size reduction) involved in making these products are manually done which results to drudgery leading to low output, poor hygiene and loss of root sap among others. To address the challenges, a mulondo crashing machine was designed and constructed to enable the increased output. The construction of the prototype was executed using stainless steel grade 316 and tested to determine the workability and time variation as compared to local methods. The machine is designed to be operated by the electric motor of size 5Hp. The machine gave a maximum output of 121.8 kg/hr, a size reduction efficiency of 100% and an average output efficiency 78% for mixed roots. This machine should meet the needs of the needs of small or medium scale mulondo enterprises.
Japanese lacquer (Urushi) has been utilized as a coating material to protect architectures and handcrafts in Japan. Previously, we characterized a Japanese lacquer film by detecting urushiol components, which are main components of a Japanese lacquer, using pyrolysis gas chromatography/mass spectrometry (PyGC/MS). PyGC/MS is effective for detecting urushiol components but does not detect lacquer polysaccharide, which more precisely characterizes Japanese lacquer. In this study, we applied the following new methods: Py/soft ionization MS (field ionization MS and chemical ionization MS), solid state nuclear magnetic resonance (NMR) spectroscopy and transmission electron microscopy (TEM) to the Japanese lacquer film. These methods were revealed to be useful to characterize the Japanese lacquer film detecting the lacquer polysaccharide.
This paper focused on the contributions of skills acquisition to alleviating the problem of unemployment in Nigeria. It blamed the high rate of unemployment in Nigeria to the type of educational system being practised. This emphasised theoretical or literacy education rather than entrepreneurial skills, technical and vocational kinds of education that could make graduates or trainees relevant in their contribution to the economy of the nation. It x-rays the need for skills acquisition, and suggests possible ways of improving the nation’s educational curriculum by introducing the dual type of educational system that encourages the acquisition of skills as well as theoretical education.
The objective of this work was to formulate a stable soluble concentrate formulation of Schiff base (Sch). The Schiff base was synthesised and its structure was confirmed using FTIR and elemental analysis techniques. The formulation was tested in vitro against ten isolates of eight important phytopathogenic fungi by the poisoned food method. In addition, different parameters related to formulation, characterisation and physical stability were determined. The results revealed that the prepared formulation exhibited good stability after preparation at different storage conditions and no separation was observed during the stability test. In addition, the percentage inhibition of mycelial growth of synthesised and formulated Schiff base increases with increasing concentration. The EC50 values of synthesised Schiff base on the tested phytopathogenic fungi; Alternaria citri, Alternaria tenuissima, Lasiodiplodia theobromae,Botrytis cinerea, isolate 1st Fusarium oxysporum, isolate 2nd Fusarium oxysporum, Macrophomina phaseolina, Pestalotia longisetula, isolate 1st Rhizoctonia solani and isolate 2ndRhizoctonia solani were 2268.78, 1556.03, 1320.76, 316.84, 3332.03, 2453, 1127.41, 2511.52, 1022.45 and 870.35 ppm. Whereas, the EC50 values of the soluble concentrate formulation were 91.95, 89.88, 41.20, 38.02, 176.62, 119.41, 34.11, 93.42, 51.14 and 25.54 ppm, respectively. The soluble concentrate formulation has a potential antifungal among control of some phytopathogenic fungi and did not induce side effect on the germination seedlings.
A simple and sensitive derivative spectrophotometric method based on the zero-crossing technique using 6-(2-naphthyl)-2,3-dihydro-1,2,4-triazine-3-thione(NDTT) for simultaneous determination of Hg(II) and Pd(II) was developed. The reagent, NDTT, reacts with mercury and palladium ions to form stable yellow and yellowish green complexes in basic media which is easily extractable with chloroform.
The second order derivative absorbance with Dλ = 31.5 at 375.5 nm and 309.0 nm were selected for the determination of Hg(II) and Pd(II), respectively. The absorbance of the complex obeys Beer’s law in the concentration range of 5-50 μg/mL and 2-35 μg/mL with r= 0.9982 and 0.9946 for Hg and Pd, respectively.
The within-day and between-day variations showed coefficient of variation (%CV) values not more than 2.8% and 3.46% for Hg and Pd respectively. The error of determination was less than 2.40%.
The proposed method was suitably applied to a synthetic and a tea sample successfully and the results were compared with atomic absorption method. The results showed that there was no significant difference between two methods.
The contribution of Art and Design to Nigeria traditional society can be one of the general inclination and practice found in almost every human society. It is insert of the contribution of people who are into the practice of the skills of their vocation or trades. The contribution is more of a variety of human activities and the products of those activities include the development of images or objects in various fields of arts such as ceramics, literature, sculpture, textile designs, music, drama, and others. Today there is so much talk about cultural revival in Nigeria society. This can only be achieved when we examine the various contributions of art and design, to see how we can utilize them in the various aspects of our tradition that needed revisited. The thrust of this paper is to access the contribution of arts and design in Nigeria cultural or traditional society.
Glycine max is a versatile food plant that when used in various forms, is capable of supplying a lot of nutrients and also capable of reducing protein malnutrition. The study evaluated the qualitative as well as morpho-agronomic characteristics of seven accessions (TGM 188, TGM 790, TGM 307, TGM 240, TGM 1210, TGM 767 and a Local variety) of G. max. The result obtained showed that TGM307 has the highest germination percentage, while TGM767 has the highest number of leaves. TGM790 has the tallest plant height as well as the shortest days to 50% flowering. TGM1210 has the largest number of pods, as well as the largest number of seeds per pod. TGM188 has the shortest day to first flowering, as well as the largest 100 seed weight. Qualitative analysis revealed that the accessions are mostly heterogeneous and morphologically diverse. Principal Component Analysis (PCA) revealed that the first three principal axes explained 89.87% of the total variation for the morphological and yield traits. The traits which furnish most of the observed variations in the accessions include number of pods per plant, number of primary branches, days to first and 50% flowering. Cluster analysis revealed that the accessions were clustered into 5 groups. The accessions in the different clusters can therefore be recommended for cultivation or used in the development of improved cultivars of G.max. Further studies should be carried out on the nutritional value of these accessions in order to determine their protein, carbohydrate or fat contents.
Study was to determine the bacteriological status of borehole water in overhead tanks at various parts of Owerri municipality. Water samples were taken from three overhead tanks in each of the 10 locations, totaling 30 samples and investigated for bacteriological characteristics. The viable bacterial, total coliform and feacal coliform counts were determined by standard plate count method, multiple tube fermentation and the use of different media respectively. The viable bacterial count ranged from 1.8 x 101 to 6.5 x 103 cfumL-1.. Total coliform and faecal coliform ranged from 0.8 to 5.2 cfu.Ml-1 and 1.3 to 8.1 cfumL-1, respectively. A total of five bacterial organisms were isolated from the stored borehole water collected, namely Staphylococcus aureus, Escherichia coli, Bacillus spp, Salmonella Typhii and Shigella spp. The presence of these pathogenic organisms is of individual risk and public health significance.
