The advent of Islam which was guided by the revelations (wahy) shaped the features of halal food cultures among local society. The result of interaction between the revelations and the local cultures created a mutual relationship in establishing the halal food culture. The accommodating and adapting processes are seen in the banning of various forms of prohibited food, such as pork, wine, carcasses, blood and such. It is present in the acceptance of local tastes (istitabah al-Malayuwiyyah) in food consumption, as in the exotic foods of local communities such as tapai, pekasam, budu, tempoyak which undergo the process of fermentation; as well as local exotic * Postgraduate Student, Department of Fiqh and Usul, Academy of Islamic Studies, University of Malaya, [email protected] ** Senior Lecturer, Department of Fiqh and Usul, Academy of Islamic Studies, University of Malaya, [email protected] ...

Kewujudan golongan ini adalah disebabkan pelbagai faktor yang menghimpit dan mendesak antaranya adalah kemiskinan bandar, konflik keluarga, gangguan mental dan gejala sosial. Bertitik tolak daripada faktor tersebut, mereka mengambil keputusan untuk tinggal di jalanan tanpa mempunyai tempat tinggal yang tetap dan sesuai. Dalam mendepani isu gelandangan, pelbagai bentuk bantuan telah diberikan kepada golongan gelandangan sama ada oleh agensi kerajaan ataupun pertubuhan bukan kerajaan, misalnya penyediaan penginapan transit, bantuan makanan dan sebagainya. Namun, dalam pengagihan zakat, tiada satu kategori asnaf yang khusus diperuntukkan bagi golongan gelandangan. Biasanya mereka dikaitkan dengan asnaf fakir miskin kerana hidup di jalanan. Sehubungan itu, untuk mengenalpasti status asnaf gelandangan, kajian ini menggabungkan antara pendekatan kepustakaan dan ...

In the past, these telescopes were absolutely calibrated by illuminating the whole aperture with a uniform large-diameter light source. This absolute calibration was performed roughly once every three years, while a relative calibration was performed on a nightly basis. In this contribution, a new technique for an absolute end-to-end calibration of the fluorescence telescopes is presented. For this technique, a portable, calibrated light source mounted on a rail system is moved across the aperture of each telescope instead of illuminating the whole aperture at once. A dedicated setup using a combination of NIST traceable photodiodes to measure the mean intensity and a PMT for pulse-to-pulse stability tracking has been built for the absolute calibration of the light source. As a result of these complementary measurements, the pulse-to-pulse light source intensity can be known to the 3.5% uncertainty level. The analysis of the readout of the PMT camera at each position of the light source together with the knowledge of the light source emission provides an absolute end-to-end calibration of the telescope. We will give a brief overview of this novel calibration method and its current status as well as show preliminary results from the measurement campaigns performed so far.

At the dawn of the multimessenger era, the interpretation of these observations within a consistent framework is important to elucidate the open questions in this field. CRPropa 3.2 is a Monte Carlo code for simulating the propagation of high-energy particles in the Universe. This new version represents a step further towards a more complete simulation framework for multimessenger studies. Some of the new developments include: cosmic-ray acceleration, support for particle interactions within astrophysical sources, full Monte Carlo treatment of electromagnetic cascades, improved ensemble-averaged Galactic propagation, and a number of technical enhancements. Here we present some of these novel features and some applications to gamma- and cosmic-ray propagation.

The development and installation of the AugerPrime upgrade of the Pierre Auger Observatory require an update of the Off line Framework to handle the additional detector components and the upgraded Surface Detector Electronics. The design of the Off line Framework proved to be sufficiently flexible to accommodate the changes needed to be able to handle the AugerPrime detector. This flexibility has been a goal since the development of the code started. The framework separates data structures from processing modules. The detector components map directly onto data structures. It was straightforward to update or add processing modules to handle the additional information from the new detectors. We will discuss the general structure of the Off line Framework, explaining the design decisions that provided its flexibility and point out the few of the features of the original design that required deeper changes, which could have been avoided in hindsight. Given the disruptive nature of the AugerPrime upgrade, the developers decided that the update for AugerPrime was the moment to change also the language standard for the implementation and move to the latest version of C++, to break strict backward compatibility eliminating deprecated interfaces, and to modernize the development infrastructure. We will discuss the changes that were made to the structure in general and the modules that were added to the framework to handle the new detector components.

The Auger Collaboration has measured and analysed an unprecedented number of UHECRs. Along with making important scientific discoveries, for example, the demonstration that cosmic rays above 8 EeV are of extragalactic origin and the observation of a new feature in the energy spectrum at around 13 EeV, outreach work has been carried out across the 18 participating countries and online. This program ranges from talks to a varied audience, to the creation of a local Visitor Center, which attracts 8000 visitors annually, to initiating masterclasses. Permanent and temporary exhibitions have been prepared both in reality and virtually. Science fairs for elementary-and high-school students have been organised, together with activities associated with interesting phenomena such as eclipses. In addition, we participate in international events such as the International Cosmic Day, Frontiers from H2020, and the International Day of Women and Girls in Science. Part of the Collaboration website is aimed at the general public. Here the most recent articles published are summarised. Thus the Collaboration informs people about work in our field, which may seem remote from everyday life. Furthermore, the Auger Observatory has been a seed for scientific and technological activities in and around Malargüe. Different outreach ventures that already have been implemented and others which are foreseen will be described.

This problem can affect the hospital budget because of delay in giving treatment and misdiagnosing. Pitfalls also occur from sample preparation until the screening of the slide. Food contaminants such as local vegetable can cause pitfall in diagnosis by mimicking the benign cell, malignant cell or the microorganism that related to human cells in cytology. Objective: The aim of this study is to describe morphologies of local vegetable cells, while to compare the morphological characteristics that have resemblances to malignant and normal cytology cells. Method: Local vegetables were crushed by using mortar and pestle, then smear on glass slides using 'pick and smear' method. Slides are stain with Papanicolaou stain and May Grunwald Giemsa stain.

This is because of inefficient waste collection systems result in smell pollution, unpleasant views, breading of insects, animal scavengers and rodents which also giving rise to a range of diseases when some waste bins are left overloaded and uncollected. As one of the efforts to overcome the inefficiency of the waste collection system problem and to achieve smart cities, an IoT (Internet of Things) based smart bin prototype is proposed in this paper. Altogether, it is an automatic centralized monitoring system that provides the timely status of a bin, enables optimal route planning for collections, reduces collection times, and saves costs as well as fuel consumption.
