    Malaysia is the second largest of palm oil producer after Indonesia, which contribute to 50 % of palm oil production. With this demand, the increasing of palm oil plantation over the years has led to the large production of agricultural waste, for example palm fibre waste. This study investigates different percentages of palm fibre (0 %, 1 %, 5 % and 10 %) to be incorporated into fired clay brick. Manufactured bricks were fired at 1 °C/min heating rate up to 1050 °C. The effects of manufacture bricks on the physical and mechanical properties of manufactured brick were also determined. All brick samples were tested due to the physical and mechanical properties which include dry density, firing shrinkage, initial rate of suction (IRS), water absorption, porosity and compressive strength. Findings show that increasing palm fibre waste affected the properties of brick, which decreased their density, besides increased firing shrinkage, IRS, water absorption, porosity and compressive strength. However, all the manufactured brick still followed the requirement

    Exploring disorganized attachment style among Malay mothers in Malaysia: a study using the Attachment Style Interview

    This article explores emerging themes involving disorganized attachment style among Malay Muslim mothers using the Attachment Style Interview (ASI). Analysis of the 18 mothers with disorganized attachment style (those with combined anxious and avoidant styles) utilized themes deemed important from the attachment research literature and selected based on a careful reading of the narrative cases. These include more extreme negative interpersonal experiences than found in other insecure attachment style descriptors, and included partner violence and related isolation/social exclusion. It also indicated more complex cognitive-affective disturbance including mixed or contradictory dependency patterns and both angry and fearful attitudes to others. We discuss the concept of disorganized attachment style in relation to abuse, social exclusion, and its implication for psychopathology, intervention, and treatment

    The Arithmetic of Calabi--Yau Manifolds and Mirror Symmetry

    We study mirror symmetric pairs of Calabi--Yau manifolds over finite fields. In particular we compute the number of rational points of the manifolds as a function of the complex structure parameters. The data of the number of rational points of a Calabi--Yau X/FqX/\mathbb{F}_q can be encoded in a generating function known as the congruent zeta function. The Weil Conjectures (proved in the 1970s) show that for smooth varieties, these functions take a very interesting form in terms of the Betti numbers of the variety. This has interesting implications for mirror symmetry, as mirror symmetry exchanges the odd and even Betti numbers. Here the zeta functions for a one-parameter family of K3 surfaces, P3[4]\mathbb{P}_3[4], and a two-parameter family of octics in weighted projective space, P4(1,1,2,2,2)[8]\mathbb{P}_4{}^{(1, 1, 2, 2, 2)} [8], are computed. The form of the zeta function at points in the moduli space of complex structures where the manifold is singular (where the Weil conjectures apart from rationality are not applicable), is investigated. The zeta function appears to be sensitive to monomial and non-monomial deformations of complex structure (or equivalently on the mirror side, toric and non-toric divisors). Various conjectures about the form of the zeta function for mirror symmetric pairs are made in light of the results of this calculation. Connections with LL-functions associated to both elliptic and Siegel modular forms are suggested.Comment: Oxford University DPhil thesis, 199 pages, 28 figure

    Unemployment is the macroeconomic problems that affect humans directly and is a complex problem that requires analysis to obtain a solution to unemployment or at least reduce unemployment. This study aimed to examine the effect of migration on unemployment entry and investment in the city of Pekanbaru. This research uses secondary data. analysis of the data in this study using multiple linear regression method. hypothesis testing using partial test (t test), simultaneous (f test), test correlation coefficient (R) and test the coefficient of determination (). the data used in this study are data on the number of unemployed, the number of migrations and the amount of investment in the city of Pekanbaru 2002-2011.The results of the testing that has been done, the entire regression test showed that all independent variables have no significant effect on the dependent variable. individual regression test showed that the number of in-migration does not significantly influence the number of unemployed in the city of Pekanbaru, and investment also no significant effect on the number of unemployed in the city of Pekanbaru. The magnitude of the effect caused by the two independent variables together on the dependent variable of 38.7%, while the remaining 61.3% is influenced by other variables not examined in this study.Keywords: unemployment, in-migration, investment

    Hukum pidana adalah salah satu konsep yang memiliki kajian yang sangat luas, hal ini dikarenakan hukum pidana yang mempunyai banyak segi, dimana masing-masing segi memiliki arti sendiri-sendiri, dan diantara kajian tersebut tidak lepas dari kajian pembahasan tentang proses penyidikan yang mengharuskan adanya pemeriksaan/penyidikan terhadap tersangka. Tersangka adalah seseorang yang karena perbuatannya atau keadaannya berdasarkan bukti permulaan patut diduga sebagai pelaku tindak pidana, sehingga tersangka merupakan salah satu aspek penting dalam menentukan kebenaran suatu perkara tindak pidana dapat diproses sesuai dengan mekanisme hukum yang berlaku. Tentang Pengadilan Anak, Undang-Undang No.23 Tahun 2002 Tentang Perlindungan Anak, Undang-Undang No. 4 Tahun 1979 Tentang Kesejahteraan Anak, Undang-Undang No. 39 Tahun 1999 Tentang Hak Asasi Manusia, Undang-Undang No. 1 Tahun 1946 Tentang KUHP, Undang-Undang No. 8 Tahun 1981 Tentang Kitab Undang-Undang Hukum Acara Pidana dan peraturan Perundang-undangan lainnya yang mengatur mengenai kesejahteraan anak, karena ”kesejahteraan anak merupakan suatu tata kehidupan dan penghidupan anak yang dapat menjamin pertumbuhan dan perkembangan anak dengan wajar baik secara rohani, jasmani, maupun sosial

    Get PDF
    The type of problem solving of mathematical words is a mathematical domain that is quite difficult for learners in primary school. This is due to learners are not only adept to the ability of numbers and counting, however, as well as related to the understanding of the text on the word problem. Schema based instruction and cognitive strategy instruction is an explicit instructional approach applied to solving word problems, especially for learners who have difficulty in the area. Both of these instructional approaches are discussed in this article along with examples of problem solving of mathematical words which are the results of previous research by experts.   Keywords: Mathematical word problem solving, schema based instruction, cognitive strategy instructio

    The remedies in respect of an offense that often typically received less attention is the protection of objects confiscated or evidence of a criminal process. Of a series of criminal justice process from the level of investigation, prosecution and up to the judge\u27s decision must include evidence that the defendant used in committing a crime. In order to evidence and secure the spoils of the State and the integrity required of a special institution to save the State Foreclosure Home Storage Objects (RUPBASAN) any institution authorized Act - legislation to implement the storage of confiscated items and loot the country. Problems in this paper is how the shape of objects confiscated and the protection of the State of booty and how the process of execution against the State confiscated objects, whereas the purpose of this paper is intended to answer questions - questions contained in the subject matter is to determine the protection of objects confiscated and State booty and to learn about the process of execution of confiscated items and loot the State. This study uses a normative juridical approach of juridical and empirical use of primary data, secondary data and tertiary data. Some fakor lack of protection for confiscated items and loot the State due to storage, research, and securing a less responsible. Efforts to protect objects of booty seized and the State in the criminal justice process is important because it has the function to strengthen the confidence of judges in assessing the truth of the material and formal errors also complete the accused and the evidence that has been defined by the Regulation
