Abstract:
Sweden has long been seen as a pioneer in the area of chemical control policy. In 1995 it put forward a so called “generation goal” which called for a phasing out of all human made chemicals within a 25 year period. The Swedish Government took up the challenge of how to best reach this goal by putting forward a number of environmental quality objectives, which were approved by the Swedish Parliament in 1999. What has happened since then? Will Sweden reach its proposed generation goal? This paper addresses these two questions.

The ordinary method for murdering weeds (unwanted plants) in a harvest manor is to shower herbicides all over the estate. This outcomes in defilement of the sustenance crops and furthermore the yield turns out to be less as a portion of the production plants pass on alongside the weeds. In this way, there is a requirement for a brilliant weed control framework. In this venture, a picture handling calculation is utilized to take pictures of the manor columns at consistent interims and after recognizing the weeds in the captured image, the weed killer chemical is showered specifically and just o

Abstract:
The use of various H2O2 based chemistries for TiW etch was studied on single wafer and wet bench tools. The focus of the investigation was put on the different behaviors of these chemicals on blanket and patterned wafers. The results of the etch rate tests showed much higher values on the wafers where copper was exposed, leading to the hypothesis that the etch rate on TiW should be driven by the catalysis effect of the transition metal on the H2O2 decomposition reaction. Additional optical inspections, ToF SIMS, SEM and TEM analyses were carried out to confirm this hypothesis and find the best

Maize (Zea mays L.) is the most important cereal crop in Kenya with 90% of the total population relying on it as the main staple food. Post-harvest loss in maize is caused by insect pests such Sitophilus zeamais and Larger grain borer and the can sometimes be up to 90 percent. Synthetic chemicals are used to manage weevil infestation in maize. However, chemical residues have been detected on the stored maize prior to consumption. Additionally, continuous uses of synthetic chemicals have led to development of pest resistance reducing their effectiveness. This study therefore sought to evaluate

In order to obtain the contact pressure distribution between the hard disc substrate and the polishing pad and its effects on the profile of polished substrate surface, the elastic contact mechanical model and mathematical equations on the chemical mechanical polishing of the hard magnetic disc substrate are established, and also the relevant boundary conditions are put forward. The contact pressure distribution is calculated with FEM, the polishing experiments are carried out and the surface profiles of polished substrates are obtained.

In Ukraine there is a complicated epizootic situation caused by the spread of serious viral diseases, in particular in the pig breeding of African swine fever (ACS) and epidemic swine diarrhea (EDS). In such conditions, the market for disinfectants is actively developing, but often drugs do not prevent the spread of viral diseases. This is due to the discrepancy in methods and doses of application, the weak effect on certain viruses and bacteria, and also the wrong organization of disinfection.

The 90s ushered in the era of molecular genetics in Pakistan.

A multitude of novel genes with previously unknown functions were discovered through genetic linkage analysis, a technique that compares the segregations of DNA markers in normal and affected family members to pinpoint the region that contains the suspect gene.

How is sensing carried out by cilia in the mouse node, zebrafish Kupffer's vesicle and similar left–right (LR) organizer organs in other species? Two possibilities have been put forward. In the former, cilia would detect some chemical species in the fluid; in the latter, they would detect fluid flow. In either case, the hypothesis is that an imbalance would be detected between this signalling coming from cilia on the left and right sides of the organizer, which would initiate a cascade of signals leading ultimately to the breaking of LR symmetry in the developing body plan of the organism.
