Kajian Prinsip ‘Eco Friendly Architecture', Studi Kasus: Sidwell Friends Middle School

Era globalisasi sekarang ini, banyak perancangan bangunan yang tidak memerhatikan keselarasan antara bangunan dengan alam dan lingkungan sekitar. Contohnya: dalam hal pemanfaatan sumber daya alam, penggunaan material dan teknologi yang tidak ramah terhadap alam. Oleh karena itu, perancangan bangunan (Arsitektur) sebagai penyumbang 45% gas CO² di bumi mempunyai andil besar memicu Pemanasan Global (global warming) dan berakibat pada turunnya kualitas lingkungan. Dari semua gejala alam yang sudah terjadi, kini sudah saatnya untuk lebih memahami alam agar tidak terjadi kerusakan alam yang lebih parah. Salah satu upaya pendekatan rancangan Arsitektur yang selaras dan ramah terhadap alam yaitu melalui Eco Friendly Architecture. Dalam prinsipnya, pembangunan akan dirancang secara holistik atau memiliki hubungan dengan ekosistem secara keseluruhan. Selain itu melalui pendekatan ini diharapkan dapat menghasilkan konsep-konsep perancangan Arsitektur yang hemat energi, ikut menjaga kelangsungan ekosistem, memanfaatkan sumber daya alam yang dapat dan tidak dapat diperbarui secara efisien dan daur ulang. Salah satu contoh penerapan konsep bangunan yang bersertifikat Eco Friendly Architecture yaitu bangunan ‘Sidwell Friends Middle School'. Dalam bangunan ini, upaya penggunaan sumber daya alam secara efisien, daur ulang dan Eco-green dilakukan untuk menjaga keseimbangan alam dengan tidak merusak tanah, air dan udara, tanpa mengabaikan kesejahteraan dan Kenyamanan manusia secara fisik, sosial dan ekonomi secara berkelanjutan

THE "GABINETTO OF GILDED STUCCO" IN THE ROYAL PALACE OF PORTICI, NAPLES (ITALY): SURVEY AND DIAGNOSIS FOR CONSERVATION

Abstract. During the 18th century architecture in Naples reached an extremely balanced synthesis between architectural spatiality and decorative apparatuses representing the most successful example of local inventiveness over history. Quite an impressive case dating back to that period is represented by the "Gabinetto of gilded stucco" in the Royal Palace in Portici. Located in the area of the palace known as Caramanico – from the name of the owner of the pre-existing building incorporated in the palace – the stucco was molded between 1752 and 1753 by the two stucco workers Angelo la Sala and Gennaro Bruscino, who also decorated the "Salotto di Porcellana" in Chinese style. Today the room, used as an academic department, is affected by quite a serious stucco decay majorly due to negligence and humidity and consisting in efflorescence, powdering and bursting, worsened by the corrosion of metal fixings. However, the present-day state of conservation of these stuccoworks represents a unique opportunity to carefully observe the original technique used to make such artworks at that time. Therefore by means of advanced surveying instruments and multi-analytical material characterization together with archival documents, the present research – set up in collaboration between University of Naples, Politecnico di Milano and CNR – aims at elaborating a thorough knowledge of an emblematic case of 18th century Neapolitan stucco with a view to its future conservation

Pengaruh Variasi Normalitas Naoh Pada Aktivasi Basafisik Zeolit Pelet Perekat Terhadap Prestasi Sepeda Motor Bensin 4-langkah

Natural zeolite is an alternative adsorbent. It needs firstly to be activated before using it as absorbent in order to get zeolite with high adsorption capacity. Previously, the use of pelletized zeolite activated by NaOH-physic and KOH-physic with varied normalities was only performed in a diesel engine to observe the engine performance.In this study there were two kinds of activation, that is chemical activation with NaOH activator variation on the normality of 0.25 N, 0.5 N, 0.75 N, and 1.0 N and physical activation with using a temperature of 220 °C for 2 hours. All are made in the form of adhesive zeolite pellets with a diameter of 10 mm and a thickness of 3 mm.From the test results and analysis showed that the use of chemically activated zeolite can improve the performance of 4-stroke petrol engine when compared without using zeolite. The best performance in this experiment obtained at the normality of 0,75 N. At road test, the pelletized zeolite can reduce the fuel consumption 23, 15 %, and 16,51 % at stationary test, and increase acceleration by 14,77 %

Root and crown tot of olive caused dy Phytophthora spp.

Phytophthora root and crown rot has been traditionally considered a minor disease of olive. However, in recent years it has been recognized as an emerging problem in several olive-growing countries such as Australia, Italy and Spain probably as a consequence of the expansion of plantings in new areas with heavy soils and the more intensive use of irrigation in both olive nurseries and commercial groves. The disease has been reported from most olive-growing countries and is caused by several soil -borne species of Phytophthora, including P. cinnamomi, P. citricola, P. cryptogea, P. drechsleri, P. gonapodyides, P. inundata, P. megasperma,P. nicotianae and P.palmivora. Diagnosis is currently based on the isolation and identification of isolates by both traditional and molecular methods. New molecular techniques are currently available that could be applied for both the identification of isolates and Phytophthora infections directly in host-tissues as well as insoil and water samples. A number of dedicated databases could improve the efficiency of these techniques. Moreover, DNA analysis has greatly contributed to phylogenetic studies of Phytophthora. Control of Phytophthora root and crown rot of olive is mainly based on preventive measures

Real-time imaging and tracking of microrobots in tissues using ultrasound phase analysis

Ultrasound B-mode imaging has been employed to monitor single agents and collective swarms of microrobots in vitro and ex vivo in controlled experimental conditions. However, low contrast and spatial resolution still limit the effective employment of such a method in a medical microrobotic scenario. Doppler-based ultrasound appears as a promising tool for tracking microrobots in echogenic and dynamic environments as biological tissues. In this Letter, we demonstrate that microrobot displacements can be used as a special signature for their visualization within echogenic media, where B-mode fails. To this aim, we induced vibrations of a magnetic soft microrobot through alternated magnetic fields and used ultrasound phase analysis to derive microrobot features such as size and position over time. By exploiting vibrations, we were able to perform imaging and tracking of a low contrast microrobot both in tissue-mimicking phantom and in chicken breast. The axial resolution was 38 μm, which is four times smaller than the B-mode resolution with the employed equipment. We also performed real-time tracking of the microrobot's positions along linear trajectories with a linear velocity up to 1 mm/s. Overall, the reported results pave the way for the application of the proposed approach for the robust monitoring of medical microrobots in tissue
