Critical Consideration

Blending of potentially acid generating (PAG) waste rock with non-PAG waste rock to create a rock mixture which performs as non-PAG is a possible approach to permanent prevention of acid rock drainage (ARD) for PAG waste rock. In 2012, a field weathering study using 300 kg samples was implemented at Teck Coal's Quintette Project located in northeastern British Columbia, Canada to test the prevention of acid generation in the PAG waste rock by dissolved carbonate leached from overlying non-PAG waste rock and direct neutralization of acidic water from PAG waste rock by contact with non-PAG waste rock.After eight years of monitoring the experiments, the layered non-PAG on PAG barrels provided proof-of-concept that as the thickness of the PAG layer increases relative to the thickness of the non-PAG layers, acidic waters are more likely to be produced. The PAG on non-PAG layering has resulted in non-acidic water and no indications of metal leaching despite accelerated oxidation in the PAG layer shown by sulphate loadings. The study has demonstrated that the scale of heterogeneity of PAG and non-PAG materials is a critical consideration for providing certainty that rock blends designed to be non-PAG will perform as non-PAG in perpetuity. This is contrary to the standard paradigm in which an excess of acid-consuming minerals is often considered sufficient alone to ensure ARD is not produced.

ABSTRACT Aedes aegypti is the predominant vector of dengue, chikungunya, and Zika viruses. This mosquito is difficult to control with conventional methods due to its container-inhabiting behavior and resistance to insecticides. Autodissemination of pyriproxyfen (PPF), a potent larvicide, has shown promise as an additional tool to control Aedes species in small-scale field trials. However, few large-scale field evaluations have been conducted. We undertook a 6-month-long large-scale field study to compare the effectiveness and operational feasibility of using In2Care Mosquito Traps (In2Care Traps, commercially available Aedes traps with PPF and Beauveria bassiana) compared to an integrated vector management (IVM) strategy consisting of source reduction, larviciding, and adulticiding for controlling Ae. aegypti eggs, larvae, and adults. We found that while the difference between treatments was only statistically significant for eggs and larvae (P < 0.05 for eggs and larvae and P > 0.05 for adults), the use of In2Care Traps alone resulted in 60%, 57%, and 57% fewer eggs, larvae, and adults, respectively, collected from that site compared to the IVM site. However, In2Care Trap deployment and maintenance were more time consuming and labor intensive than the IVM strategy. Thus, using In2Care Traps alone as a control method for large areas (e.g., >20 ha) may be less practical for control programs with the capacity to conduct ground and aerial larviciding and adulticiding. Based on our study results, we conclude that In2Care Traps are effective at suppressing Ae. aegypti and have the most potential for use in areas without sophisticated control programs and within IVM programs to target hotspots with high population levels and/or risk of Aedes-borne pathogen transmission.

Soccer Training

Small sided-games training is a small-scale field, an appropriate situation developed for young players, so they can learn and develop. Small sided games training is also one of the methods of soccer training using smaller fields with fewer players. This training method  is a fairly effective exercise in physical improvement, techniques and tactics Passing is to feed the ball or pass the ball to a friend, while passing determination is the ability to set goals / pass the ball according to the goal or target. This research is an experimental research conducted with the aim to find out whether or not there is a result of something done on the sample to be studied. The research began with a pretest and ended with a posttest. The number of samples in this study amounted to 20 people. The training given was done during 16 meetings. This research was tested using a statistical analysis of the hipotsis test (t test). Based on data analysis, it can be concluded that the small sided games exercise gives a significant effect on the accuracy of passing on extracurricular students at SMP Negeri  1 Muaro Jambi, proven in the pre-test and post-test assessments with an average pre-test = 505 and post-test = 7.65, with the increment difference of 7.65. This can be seen by the T test that is Tcount = 3.492787 ˃ Ttable = 1.72913. Based on the results of research and  calculations from the data and discussions that have been carried out, this research proves that there is an influence of small sided games training on the passing accuracy of extracurricular students at Muaro Jambi State Junior High School.
