The study was conducted during the period 2010-2012 in the Faculty of agriculture at the University of Tishreen, with a view to obtain organic fertilizer (sludge with plant waste), through compost it in the form of a pile within an isolated device. The changes have been monitoring with some physical and chemical properties of the fermented substance for the duration of fermentation, by taking samples each month and analyzed them in the laboratory. The study has included change physical and chemical residue during the fermentation process, where the temperature has reached in the center of pile to 70 degrees Celsius and the device temperature exceeded 70 degrees Celsius to 72 degrees Celsius, and either of the pH in the fermented substance had arrived to the 7.4in the pile and 7.45 in the device, the percentage had dropped C/N from 30/1 to 18/1 of the pile and 17/1 of the device, showing the death of 99% of the huminth eggs of the intestinal worms after 26 days from the beginning of the composting process by crumpling and 97% of the huminth eggs intestinal worms had died after 10 days from the beginning of the composting process in the device.

Research summary
أجريت الدراسة في كلية الهندسة المدنية بجامعة تشرين خلال الفترة 2010-2012 بهدف الحصول على سماد عضوي من الحمأة والمخلفات النباتية. تم تخمير هذه المواد في كومة وجهاز معزول، وتمت مراقبة التغيرات الفيزيائية والكيميائية للمخلفات خلال عملية التخمير. وصلت درجة الحرارة في مركز الكومة إلى 70 درجة مئوية وفي الجهاز إلى 72 درجة مئوية. انخفضت نسبة C/N من 30/1 إلى 18/1 في الكومة و17/1 في الجهاز. كما تبين موت 99% من بيوض الديدان المعوية بعد 26 يوماً من بداية التخمير في الكومة و97% بعد 12 يوماً في الجهاز. تهدف الدراسة إلى إيجاد طريقة للاستفادة من الحمأة والمخلفات النباتية في إنتاج سماد عضوي آمن وفعال، مما يساهم في حماية البيئة وتعزيز الاقتصاد الوطني.
Critical review
دراسة نقدية: تعتبر الدراسة خطوة هامة نحو الاستفادة من الحمأة والمخلفات النباتية في إنتاج سماد عضوي، إلا أن هناك بعض النقاط التي يمكن تحسينها. أولاً، لم تتناول الدراسة بشكل كافٍ تأثير العوامل البيئية المختلفة على عملية التخمير، مثل الرطوبة والتهوية. ثانياً، كان من الممكن أن تكون الدراسة أكثر شمولية إذا تضمنت تجارب ميدانية إضافية في مناطق مختلفة لتأكيد النتائج. وأخيراً، يجب أن يتم التركيز على تحليل التكلفة الاقتصادية لهذه العملية مقارنة بالأسمدة الكيميائية التقليدية.

Languages evolve over time and the meaning of words can shift. Furthermore, individual words can have multiple senses. However, existing language models often only reflect one word sense per word and do not reflect semantic changes over time. While t here are language models that can either model semantic change of words or multiple word senses, none of them cover both aspects simultaneously. We propose a novel force-directed graph layout algorithm to draw a network of frequently co-occurring words. In this way, we are able to use the drawn graph to visualize the evolution of word senses. In addition, we hope that jointly modeling semantic change and multiple senses of words results in improvements for the individual tasks.
The study was conducted to determine the efficiency of the aerobic treatment of primary sludge resulting from sewage sedimentation and to determine the optimum residence time by measuring the indicators of total solids, chemical oxygen demand, organic content and dewatering ability of the sludge.
Conversation disentanglement aims to separate intermingled messages into detached sessions, which is a fundamental task in understanding multi-party conversations. Existing work on conversation disentanglement relies heavily upon human-annotated data sets, which is expensive to obtain in practice. In this work, we explore training a conversation disentanglement model without referencing any human annotations. Our method is built upon the deep co-training algorithm, which consists of two neural networks: a message-pair classifier and a session classifier. The former is responsible of retrieving local relations between two messages while the latter categorizes a message to a session by capturing context-aware information. Both the two networks are initialized respectively with pseudo data built from the unannotated corpus. During the deep co-training process, we use the session classifier as a reinforcement learning component to learn a session assigning policy by maximizing the local rewards given by the message-pair classifier. For the message-pair classifier, we enrich its training data by retrieving message pairs with high confidence from the disentangled sessions predicted by the session classifier. Experimental results on the large Movie Dialogue Dataset demonstrate that our proposed approach achieves competitive performance compared to previous supervised methods. Further experiments show that the predicted disentangled conversations can promote the performance on the downstream task of multi-party response selection.
This paper explores the legal issues surrounding the co-operation with international tribunals, taking into consideration the fact that successful implementation of the international tribunals and the tribunals of international character rely solely upon the full co-operation of third states with these same tribunals. It is precisely because the work of these tribunals relates to other states, that the co-operation of those states with these tribunals is essential both in investigative procedures and to secure successful prosecutions. Due to the fact that the Special Tribunal for Lebanon (STL) is the first tribunal of international character in the Middle East, this paper will concentrate on the co-operation of third States with the STL and its judicial governance concerning third states. It will take into consideration how the international legal obligations that have constructed the posture of the STL have impacted upon its judicial relationship as regards third states co-operation. While the Agreement between the United Nations (UN) and Lebanon provides a solid framework for co-operation between the STL and Lebanon, the Security Council Resolution 1757 (2007) is silent as regards the duty of third states to assist the Tribunal. As a result, the STL will be confronted with a variety of obstacles and problems in obtaining co-operation of third states-including Syria- which may seriously impede the functioning and effectiveness of the STL as a whole and undermine its legal capacity. The importance of Syrian co-operation with the STL does not just bear upon the functioning and effectiveness of the legal capacity of the STL; but rather any failure on the part Syrian co-operation could also have serious consequences for Syria itself. Conditional or limited co-operation would benefit Syria in several ways. It would protect Syria from being placed under any threats of the UN issuing resolutions under Chapter VII of the UN Charter to oblige all states to co-operate with the STL. Such resolutions could impact negatively upon Syria as a whole. Any negative impact upon Syria as a result of its failure to co-operate with the STL could include the possibility of the UN imposing economic sanctions or even the threat of interventional force, although the latter may be unlikely but nevertheless may still exist as a possible, albeit extreme, course of action to force Syria to co-operate. The importance of Lebanon to co-operate with the STL is also beneficial for Lebanon. Firstly, Lebanese co-operation will achieve the objective of the STL which is to enable and facilitate the full extent of justice to run its course. This is not just for the benefit of the victims and their families, but also to address and deter the political assassinations and trans-boundary terrorism which has affected Lebanon. Therefore, this article attempts to address the co-operation issues related to the tribunals. As the STL is the first tribunal in the Middle East, it will be this tribunal which will be the subject of detailed study in this paper. This paper will then conclude whether Syria is within its legal remit to choose whether to co-operate with the STL or not or whether it retains the right, as set out in its own Constitution, to try any potential suspects under Syrian law and within the Syrian judicial system.
