Abstract
Careful scrutiny of knowledge collected throughout the forest inventory within the Nineteen Sixties on the brush reveals absence of seedlings of magnoliopsid genus welwitschii. This study wanted to see why magnoliopsid genus welwitschii doesn't regenerate within the forest and to look at the roles of predispersal and post-dispersal drupes and seed predation intensities as precipitators of lack of regeneration. Seed/drupe predation experiments were conducted at 2 levels. the primary level examined pre-dispersal seed and stone fruit predation. Rectangular seed/drupe traps created out of meshed material with a grouping surface of zero.25 m2were willy-nilly placed to hide all the four quadrants underneath the cover of 5 randomly chosen magnoliopsid genus mature trees. The second level examined post-dispersal predation by sampling seeds and drupes underneath the crown of every of the willy-nilly chosen mature trees by dividing it into four quadrants. at intervals every quadrant, 5 1m2 quadrats were established on the bottom in a very random fashion to hide a minimum of 10-30 per cent of the full cover space. Frequency- and distance- dependent seed/drupe predation were examined exploitation thirty (l m2) quadrats with equal numbers of seeds and stone fruits and inspected each twelve hours for one month to see variations in seed and drupe predation rates. Effects of density and distance were tested by fitting fifty m long transects with the bottom of the mature trees because the start line. 2 transects per tree in two totally different directions, north/south and east/west at 5 mature trees were established. on every transect, eleven sampling stations were established at a 5 metre interval. A saddlery grid was established underneath the crown of 5 mature magnoliopsid genus adults and aloof from the crown to see variations in little vertebrate predator density. Results of predispersal drupes predation was derived from the pooled sample of all drupes collected. a complete of 1386 drupes were collected. Of these, 3 (3) per cent had insect holes. a more in-depth examination of size and weight of the drupes that were attacked unconcealed that smaller drupes (70%) were attacked quite larger ones (30%). Overall, there have been additional little drupes falling on the forest floor (89 per cent) than giant ones (11 per cent). stone fruit and seed density was a decreasing operate of distance from the parent trees ad distance from the parent trees had a big impact on drupes and seed predation rates. irrespective of density, seeds were removed at higher rates underneath the parent crowns, whereas drupes were unnoticed by the predators.

Abstract
A computational study on the decomposition reaction of a series of diazo aldehydes (CHO-CRN2), with the groups R=H, CH3, phenyl, i-C3H7, cyclo-C3H5, NH2, Cl and OH has been carried out. Optimization and frequency calculations on anti and syn isomers have been performed at the MP2/6-31G(d) level of theory. Based on the results, the reaction mechanism for each compound was interpreted from the possible interactions of the substituent groups with the intermediate and its influence on the reaction rate. The reaction for almost all substituents used proceeded by Wolff rearrangement in two steps, the first of them being the rate-determining step. Substituents groups with a giver capacity of π charge, such as NH2 and OH, improve the rate of decomposition of diazo aldehydes. The bonding characteristics of all the species involved in some of the studied reactions have been investigated by the natural bond orbital (NBO) analysis.

Abstract
The study focused on the effects of improvised and standard teaching materials on students attitude towards chemistry in Idah local government area of Kogi state, Nigeria. The aim of the study is provide an objective basis for taking instructional decision relating to more effective utilization of improvised and standard teaching materials in teaching and learning chemistry, thereby ensuring students positive disposition towards chemistry. The study was guided by a research question and a hypothesis. Quasi-experimental design was employed for this study; specifically the pre-test, post test, non-equivalent and non-randomized control group. The population of the study consisted of the senior secondary one (SS1) in Idah local government of Kogi state. A sample made up of 378 SS1 students were randomly drawn from intact classes of each of the six schools for the study, using multi stage sampling technique. A 20-item researcher developed instrument titled chemistry attitude scale (CAS) was used to collect data. Mean and standard deviation were used to answer the research question, while the analysis of covariance (ANCOVA) was used to test hypothesis. Finally, turkey procedure was used to indicate the direction of the difference. The result showed that the students attitude toward chemistry were significantly enhanced by their being exposed to the improvised and standard teaching materials types. However, no significant differences existed between improvised and standard teaching materials in enhancing students attitude towards chemistry. The educational implications, therefore is that this study has acted to wipe away the notion that standard teaching materials is superior to improvised counterparts. And since there are abundant local teaching materials in Nigerian environment, lack of standard teaching materials should no longer be a good reason for chemistry teachers not to ensure effective teaching and learning. Therefore it was recommended that chemistry teachers and students should endeavor to use improvised teaching materials in absence of the standard ones.
