This paper predicts and compares the carbon monoxide (CO) concentration levels along Sembulan Road for years 2004 and 2014 using CAL3QHC air dispersion model at two major locations, i.e., at Sembulan Roundabout and Sutera Harbour Intersection, Kota Kinabalu, Sabah, Malaysia. The CO concentration “hot-spots” were also identified at Sutera Harbour Intersection, and the highest MAXIMUM 1-hr average ground level concentrations of CO modeled for Kpg. Air Sembulan located in the northeast of idling road was 9.33 ppm for year 2004. This study showed that there would be no extreme changes in CO concentration trends for year 2014 although a substantial increase in the number of vehicles is assumed to affect the level of CO concentrations. It was also found that the CO levels would be well below the Malaysian Ambient Air Quality Guidelines of 30 ppm for 1-hour Time-Weighted Average (TWA). Comparisons between the modeled and observed outputs using quantitative data analysis technique and statistical methods indicated that the CAL3QHC predicted results correlated well with measured data. It was predicted that receptors located near to the major intersection, in the long-term would be potentially exposed to relatively higher CO levels.

Continue the policy of subsidizing input of production could be one factor contributing to the low efficiency of input and thus prevent the development of the country. In this study, positive mathematical programming approach according to MAXIMUM entropy was used to evaluate effects of eliminating the water subsidy on the production of ornamental flowers. Data were collected by from beneficiaries of ornamental flowers of Mahalat city, during crop year 2013-2014. The results showed that the policy of increasing prices of water lead to decline in production and benefit.The MAXIMUM decrease in production is related to wallflower, Lilium and is Gerber respectively. The results showed that the flowers of Lilium and Gerber have higher economic performance compared to other types of produced flowers and the most production decrease is related to Shabbo.

Shastadaisy are from composite family and it is as a part of ornamental flowers of spring and summer would plant in green spaces of cities and consumers’. Shastadaisy has capitule inflorescence the present research aims to study and review its genesis and comparison definition of ray and disk flowers. It can be suitable pattern for several species of capitule inflorescence, floral buds of shadtadaisy flowers, different phases of originating, creation of after primitive studies with stereomicroscope, fixation with FAA. More observation of inflorescence and floret has been done by SEM microscopy. Results showed that procreative meristem, dimension of meristem and its dyeability are increased and meristem during originating to the floret morphological alternation from convex shape in to the flat one and then become dented at the location of central florets which can be raised from more rapid growth of marginal florets, their shape found, pressure in to the central floret meristem. This portioning can be resulted the controlling of cells dividing and cell growth in grooved regions and cells division continues in each floret meristim portion. In progress originating phase’s meristem of each bolted floret would start new portioning in margin of the inflorescence and different parts of each floret is included as stripes sepals, 5 stamens and bolted in receptacle part. three types of ray floret are included as hormapherodit-floret, pistil-floret and sterile florets which had been existed in scattered. Pistils have bifurcate stigma, the homogeneous cells’ style, alveolus ovary and inverted ovules, disk florets originating from margine toward center and each meristem portion beginning of its floret parts formation. Pollengrains types are Tri-colporate. Originating of pollengrains in another is in-simultaneously beside one or two cells pollens. The second mitosis division is caused the formation of tri-cells pollens.

Given a set $P$ of $n$ points in the plane, the MAXIMUM triangle problem asks for finding a triangle with three vertices in $P$ that encloses the MAXIMUM number of points from $P$. While the problem is easily solvable in $O(n^3)$ time, it has been open whether a subcubic solution is possible. In this paper, we show that the problem can be solved in $o(n^3)$ time, using a reduction to min-plus matrix multiplication. We also provide some improved approximation algorithms for the problem, including a 4-approximation algorithm running in $O(n \log n \log h)$ time, and a 3-approximation algorithm with $O(nh \log n + nh^2)$ runtime, where $h$ is the size of the convex hull of $P$.
