The challenges for chemistry education in Africa

The continent of Africa is made up by many country borderlines, but as we know, borders are only lines on a map. Nature and the environment don’t recognize these borders, and therefore, issues of climate change, air  pollution, water quality and diseases require collaborations among nations for their solutions. A new way of thinking, teaching and learning chemistry is also required. Chemistry will play a major role in solving the challenges that face our planet and the development of the continent of Africa. We must have chemists who will be able to solve these problems. In order to have these types of chemists, we must have, in the pipeline, students who will become the future chemists able to offer solutions to existing and new problems. This means developing a new curriculum and new methods of teaching chemistry so that chemistry can be accessible to all students in Africa. Sadly enough, many students shy away from chemistry. In order to attract students to chemistry, creative methods for teaching and learning were developed for all levels, from primary school to university, and from the formal to the informal settings. These methods utilize the students’ talents, hobbies, interests and cultural backgrounds. Equal access to  science education is a human right that belongs to all [1-2]. If we do not guarantee science education to all, we will form a two-class society divided not by royalty and status, but by knowledge of science. The centerpiece for this method is the development of student projects, which help them to remember and understand abstract scientific concepts. An old Chinese proverb says: “I hear and I forget; I see and I remember; I do and I understand.” These students’ projects take advantage of seeing and remembering, doing and understanding. Through this process, students are active learners, instead of being passive observers. To demonstrate their understanding of scientific concepts through their projects, the  students use a media of their choice, from drawing, dance and drama (no tech) to computer animation (high tech). Projects can also take the form of paintings, sculptures, songs, films, and scripts for theater. These projects are used as alternative assessment methods where the whole class is involved in the assessment process. In order for this method to be  successful, workshops for teachers as well as parents must be conducted. This way, the students will be taught in a creative way in school and  through the joint involvement of teachers and parents, students will be encouraged to pursue chemistry. After all, “it takes a village to raise a child,” as the African proverb states. [AJCE 4(2), Special Issue, May 2014

ABSTRAKJudul: Pengaruh Infasi, Kurs dan Neraca Modal (Capital Account) di IndonesiaNama: Sri Indriana ZMNIM: 1201101010163Fakultas/jurusan: Ekonomi/Ekonomi PembangunanDosen Pembimbing: Amri.,S.Si.M.SiKonsentrasi: Ekonomi MoneterPenelitian ini bertujuan untuk menganalisis pengaruh antara variabel inflasi, kurs dan neraca modal di Indonesia dengan menggunakan model Vector Autoregressive (VAR). Data yang digunakan adalah data kuartalan dari tahun 1990.1 sampai 2014.4. Hasil penelitian menunjukkan bahwa terjadi kausalitas dua arah antara variabel inflasi, kurs dan neraca modal. Selanjutnya hasil uji Impulse Response Function menunjukkan bahwa shock (guncangan) inflasi dan kurs akan memberikan dampak terhadap neraca modal. Begitu pula sebaliknya shock dari neraca modal direspon cepat oleh inflasi dan kurs. Hasil uji FEVD (Forecast Variance Decomposition) menunjukkan bahwa ketiga variabel yaitu inflasi, kurs dan neraca modal tersebut saling memberikan kontribusi dalam memengaruhi variabel lainnya. Oleh karena itu, mengingat inflasi dan kurs memberikan pengaruh yang signifikan terhadap neraca modal Indonesia, maka upaya menstabilkan nilai tukar rupiah dan menekan inflasi agar tidak terlalu tinggi perlu dilakukan oleh Bank Indonesia.

Nonparametric estimation for the ruin probability in a Lévy risk model under low-frequency observation

In this paper, we propose a nonparametric estimator for the ruin probability in a spectrally negative Lévy risk model based on low-frequency observation. The estimator is constructed via the Fourier transform of the ruin probability. The convergence rates of the estimator are studied for large sample size. Some simulation results are also given to show the performance of the proposed method when the sample size is finite.postprin

Heat release rate markers for premixed combustion

The validity of the commonly used flame marker for heat release rate (HRR) visualization, namely the rate of the reaction OH + CH2O ⇔ HCO + H2O is re-examined. This is done both for methane–air and multi-component fuel–air mixtures for lean and stoichiometric conditions. Two different methods are used to identify HRR correlations, and it is found that HRR correlations vary strongly with stoichiometry. For the methane mixture there exist alternative HRR markers, while for the multi-component fuel flame the above correlation is found to be inadequate. Alternative markers for the HRR visualization are thus proposed and their performance under turbulent conditions is evaluated using DNS data.ZMN and NS acknowledges the funding through the Low Carbon Energy University Alliance Programme supported by Tsinghua University, China.

Direct Numerical Simulation of Complex Fuel Combustion with Detailed Chemistry: Physical Insight and Mean Reaction Rate Modeling

Direct numerical simulation of freely-propagating premixed flames of a multicomponent fuel is performed using a skeletal chemical mechanism with 49 reactions and 15 species. The fuel consists of CO,H2,H2O,CH4 and CO2 in proportions akin to blast furnace gas or a low calorific value syngas. The simulations include low and high turbulence levels to elucidate the effect of turbulence on realistic chemistry flames. The multi-component fuel flame is found to have a more complex structure than most common flames, with individual species reaction zones not necessarily overlapping with each other and with a wide heat releasing zone. The species mass fractions and heat release rate show significant scatter, with their conditional average however remaining close to the laminar flame result. Probability density functions of displacement speed, stretch rate, and curvature are near-Gaussian. Five different mean reaction rate closures are evaluated in the RANS context using these DNS data, presenting perhaps the most stringent test to date of the combustion models. Significant quantitative differences are observed in the performance of the models tested, especially for the higher turbulence level case.ZMN and NS acknowledges the funding through the Low Carbon Energy University Alliance Programme supported by Tsinghua University, China.
