THERMAL PERFORMANCES OF DIFFERENT TYPES OF UNDERGROUND HEAT EXCHANGERS
Authors: Omer Abdeen
Published: May 2020

Globally buildings are responsible for approximately 40% of the total world annual energy consumption. Most of this energy is for the provision of lighting, heating, cooling and air conditioning. An increase in awareness of the environmental impact of CO2, NOx and CFCs emissions triggered a renewed interest in environmentally friendly cooling and heating technologies. Under the 1997 Montreal Protocol, governments agreed to phase out chemicals used as refrigerants that have the potential to destroy stratospheric ozone. An approach isneeded to integrate renewable energies in a way to achieve high building performance standards. However, because renewable energy sources are stochastic and geographically diffuse, their ability to match demand is determined by the adoption of one of the following two approaches: the utilisation of a capture area greater than that occupied by the community to be supplied, or the reduction of the community’s energy demands to a level commensurate with the locally available renewable resources. Ground source heat pump (GSHP) systems (also referred to as geothermal heat pump systems, earth-energy systems and GeoExchange systems) have received considerable attention in recent decades as an alternative energy source for residential and commercial space heating and cooling applications. The GSHP applications are one of three categories of geothermal energy resources as defined by ASHRAE and include high-temperature (>150°C) for electric power production, intermediate temperature (<150°C) for direct-use applications and GSHP applications (generally (<32°C). The GSHP applications are distinguished from the others by the fact that they operate at relatively low temperatures.

Authors: Bukunmi O Adegbenle
Published: May 2020

Laterite samples from Ede area with particle components of 19.7% clay, 32.8% silt and 47.5% sand was stabilized with combined cement, lime and bitumen and test for Compressive strength, Linear Shrinkage, Permeability and Water Absorption. The stabilizers were mixed with laterite soil in different ratios and percentage. The laterite carried 90% which is constant while the three stabilizers shared the remaining 10% in varying form. After 28 days of curing, laterite stabilizer with 90% of laterite, 8% of cement, 1% lime and 1% bitumen (LCLB1) possessed compressive strength of 2.01N/mm2. It Water Absorption Capacity was 3.05%. LCLB4 stabilizer (90% laterite, 6% cement, 2% lime and 2% bitumen) has the same compressive strength with LCLB1 stabilizer but with a high Water Absorption Capacity of 4.2%. The stabilizer of 90% laterite, 3.33% cement, 3.33% lime and 3.33% of bitumen (LCLB8) has the lowest compressive strength of 0.74N/mm2 and the highest Water Absorption Capacity of 5.39%. The results shows that LCLB1 stabilizer is a better stabilizer for strength and blocks made from laterite stabilized with it stand a good alternative to sand Crete blocks in building constructions. The combination of these stabilizers in order to determine a most economical volume combination for optimum performance is highly possible and economical.

Published: May 2020

Fisheries management involves, among other things, knowledge of the actors and the catching gear used. These data are generally absent in the fisheries of Côte d'Ivoire. However, there is a strong fishing activity. To lead this study, surveys were conducted among fishermen and fishery administrators. The study of fishing activity in the area of Dioulabougou (Côte d’Ivoire, West Africa) in the district of Bouaflé done from November 2013 to February 2014 identified 88 fishermen. This population is composed of ivorians (39.77%) and foreigners (60.23%). The fishing activity is led by malians (Bambara ethnic group): 34.1%. Baoulé ethnic group (29.54% of ivorian fishermen) is the greatest ethnic group of ivorians. Two categories of fishermen stand in the fishing activity. We registered professional fishermen whose job is only fishing (84.1%) and professionals with another activity (4.5%). The fishing activity in Dioulabougou is dominated by adult aged more than 45 years (48%). Fishermen are predominantly illiterate at 42.04%. The fishing techniques used at Dioulabougou are conical fishing baskets (mesh and trunk of ronier), bamboo-traps, gillnets, bottom lines and shore seines. The illiterate situation of fishermen isa serious matter for sustainable management on fish’s resources.

DISTRIBUTION AND ABUNDANCE OF PHYTOPLANKTON IN VEMBANAD ESTUARY, A RAMSAR SITE ON SOUTH WEST COAST INDIA
Authors: Nandan S.Bijoy , Sajeevan K.
Published: May 2020

The phytoplankton abundance and distribution from the Vembanad estuary, south west coast of India was studied for a period of two years from March, 2011 to February, 2013. A total of 73 genera of phytoplankton were recorded and Bacillariophyceae formed the dominant group in all seasons of the study. The constant addition of nutrients particularly, nitrate and phosphate based fertilizers used in the Kuttanad paddy fields enhanced the phytoplankton production in the estuary. During 2011-2012 and 2012-2013 period, phytoplankton biomass varied from 2 to 46 ml/m3 (av. 11.09 ml/m3) and 1 to 26 ml/m3 (av. 5.78 ml/m3) respectively. Phytoplankton biomass, distribution and species composition showed variations in contrast to the prevailing water temperature, light intensity (Secchi disc visibility), nutrient availability, grazing pressure, tide and water movements, and seasonal pattern and even with time of day. The salinity regime of the water body also influenced the phytoplankton distribution in the study locations. Phytoplankton production showed a higher value in the northern as compared to the southern zone. Thus, the mesohaline condition prevailing in the northern zone of the estuary supported higher abundance and diversity of phytoplankton species which in turn contributed to higher production rate.
A STUDY ON GEOGRAPHICAL ROUTING WITH ADAPTIVE POSITION UPDATE
Authors: Anandakrishnan N. , Roshini Neena
Published: May 2020

Geographical Routing is a routing methodology mainly used for wireless mobile networks (Mobile Adhoc Networks, MANETs). MANETs are comprised of mobile nodes or mobile computing devices which are free to move randomly and thus the network's wireless topology may also change randomly. In Geographical Routing, nodes need to maintain the current positions of their neighbors for making forwarding decisions and hence the Adaptive Position Update (APU) method is proposed. Based on the flexibility of the nodes and the forwarding decisions made in the network, APU dynamically keeps in track of the rate of position updates. It is based on nodes with movements which are complex to predict their updated positions frequently and also the nodes which are closer to forwarding paths and update their positions more frequently. The APU is validated by network simulations showing that APU can potentially reduce the traffic load and acknowledge the mobility of nodes. It also improves the routing performance in terms of packet delivery ratio and packet delays.

Published: May 2020

Infiltration is treated as one of the important parameter of the hydrological cycle as far as ground water recharge is concerned. It depends on soil characteristics such as soil texture, hydraulic conductivity, soil structure, vegetation cover, porosity, permeability, degree of saturation etc. Determination of infiltration rates is useful for mitigation of hydrological riskand reflects the future of ground water resources in the study area. Infiltration of water into the soil is determined by a simple instrument called Double ring infiltrometer. Infiltration models are the empirical formulae developed using infiltration concepts which is used to determine the infiltration rate of soil. One way ANOVA test was performed to find the significance of the infiltration models. In the present study an attempt is made to validate the Horton’s model, Green ampt model and Kostiakov’s infiltration model with observed field data for a residential area, Ernakulam. From the present study significant model for the particular site is determined by using decision factor analysis.

NPK Levels and Application Methods on Productivity of Amorphophallus muelleri Blume in Intercropping System
Authors: Santosa Edi , Dinurrohman Susila Anas , Pieter Lontoh Adolf , Mine Yoko , Sugiyama Nobuo
Published: May 2020

Underground corm of Amorphophallus muelleri Blume contained glucomannan, a raw material widely used in beverage, food and medicinal industries. In Indonesia, A. muelleri is grown under intercropping system, however, average corm production was considered low. The low productivity could be related to the low input of chemical fertilizers. Therefore, the effects of NPK fertilizers and methods of application on A. muelleri productivity were evaluated in the present study for intercropping system. Two experiments were conducted at Leuwikopo Experimental Farm, Bogor, Indonesia from 2010-2012 under canopy of coffee trees. First experiment was conducted using four levels of N, P, and K applications, i.e., N:P2O5:K2O at the rate 0:0:0, 100:60:80, 125:60:100 and 150:60:120 kg ha-1. In second experiment, N:P2O5:K2O fertilizers at the rate of 100:60:80 were applied by conventional (solid) and liquefied. Results of first experiment showed that application of N, P and K at rate of 100 kg, 60 kg, and 80 kg ha-1 produced fresh corm weight 636.3±91.7 g per plant or increased by 63% higher than control. However, higher rate of NPK application did not increase corm yield, possibly due to the occurrence of leaf discoloration. Higher rates of NPK also delayed harvest time 1 to 2 weeks compared with control and caused wide variation of corm size. Thus, excess application of NPK should be avoided for high productivity of A. muelleri. Second experiment showed that there was no significant different among methods of application on fresh corm weight, i.e., 413 g and 396 g from conventional and liquefied applications, respectively. These experiments conclude that application of NPK is important to enhance A. muelleri production in intercropping system.

Analisis Gerombol Simultan dan Jejaring Farmakologi antara Senyawa dengan Protein Target pada Penentuan Senyawa Aktif Jamu Anti Diabetes Tipe 2
Authors: Qomariasih Nurul , Susetyo Budi , Mochamad Afendi Farit
Published: May 2020

Selama ini pembuatan obat untuk menyembuhkan suatu penyakit masih menargetkan hanya satu protein khusus yang menjadi penyebab penyakit tersebut, yang tentu hanya menggunakan satu senyawa aktif. Padahal selain menimbulkan efek samping, penanganan suatu penyakit perlu menyasar banyak protein sekaligus. Sehingga, baru-baru ini terjadi perubahan paradigma dari “one drug, one target” menjadi “multi-components, network target”. Paradigma baru ini telah melahirkan beberapa penelitian untuk menghasilkan formulasi jamu, hal ini dikarenakan konsep formulasi jamu memerlukan beberapa senyawa aktif yang terlibat. Formula jamu yang diteliti sebagai upaya menyembuhkan penyakit Diabetes Melitus (DM) tipe 2 terdiri dari 4 tanaman yaitu Pare (Momordica charantia), Sembung (Blumea balsamifera), bratawali (Tinospora crispa), dan jahe (Zingiber officinale) berdasarkan hasil penelitian Nurishmaya tahun 2014 serta berdasarkan ramuan jamu yang sedang dikembangkan di Pusat Studi Biofarmaka, Bogor. Evaluasi senyawa yang berkaitan dengan DM tipe 2 dilakukan dengan terlebih dahulu menambahkan 19 obat sintetis yang ditujukan untuk DM tipe 2 dari basis data Drug Bank. Sehingga terdapat total sebanyak 74 senyawa aktif yang terdiri dari 55 senyawa alami dari tanaman dan 19 senyawa sintetis obat. Sebanyak 100 protein yang berkaitan erat dengan masing-masing senyawa diperoleh melalui hasil skor konkordan DrugCHIPER. Skor konkordan tersebut kemudian digunakan dalam analisis gerombol simultan antara senyawa dan protein target. Plot komponen utama dan submatrix penggerombolan simultan menunjukkan 2 dari 3 senyawa dari bratawali sangat dekat dengan kelompok sintetis. Selain itu, ada 11 dari 44 senyawa dari Jahe terkumpul bersama dengan senyawa sintetis tetapi dalam jarak yang jauh. Sedangkan berdasarkan jejaring kemiripan, lebih spesifik lagi terdapat 17 dari 19 senyawa obat sintetis yang memiliki kemiripan berdasarkan protein target dengan 2 senyawa tanaman Bratawali dan 5 senyawa tanaman Jahe.

Kenagarian Sungai Durian merupakan kawasan yang rawan terkena bencana banjir. Hal tersebut karena lokasinya yang berada di sekitar Daerah Aliran Sungai (DAS). Masyarakat setempat juga masih memiliki pengetahuan yang rendah tentang pegelolaan DAS sehingga menyebabkan kebanyakan mereka dalam hal memanfaatkan DAS tersebut lebih cenderung mementingkan kepentingan pribadi dibandingkan dengan kepentingan bersama. Salah satu contohnya adalah masih banyaknya masyrakat setempat yang melakukan aktifitas penambangan sirtukil dan penebangan pohon di sekitar DAS, hal ini dapat berdampak terhadap badan sungai ketika terjadi hujan lebat dan dalam waktu yang cukup lama. Kebanyakan masyarakat sebagai petani dan penambang sirtukil sebagai penghasilan tambahan, menurut Wali Nagari Sungai Durian (2018). Perlu adanya sosialisasi mitigasi bencana banjir melalui penenaman pohon sebagai upaya untuk mengurangi dan memperkecil bencana banjir secara tepat dan cepat. Metode yang digunakan untuk melaksanakan kegiatan pengabdian kepada masyaakat ini adalah sosialisasi dan aksi penanaman pohon. Sosialisasi terlaksana dengan baik karena ada kerjasama dengan mitra yaitu Wali Nagari Sungai Durian. Sosialisasi dilakukan kepada masyarakat langsung ke rumah-rumah yang berada di sekitar DAS sehingga mereka menanam bibit di lahan miliknya. Penanaman pohon juga di lakukan di tanah kosong milik kaum di pinggiran sungai. Masyarakat dapat memahami pentingnya penanaman pohon di pinggiran sungai setelah dilakukan sosialisasi mitigasi bencana banjir melalui penanaman pohon.

A hybrid welding technique formed by combining keyhole plasma arc welding (KPAW) and pulsed gas metal arc welding (GMAW-P) is characterized by the complex interactions of the arc, droplet, keyhole, and weld pool. With the help of a high-speed video camera, zirconia particles, and a thermal camera, the complex interactive phenomena of the hybrid KPAW–GMAW-P process was analyzed. Owing to the formation of a direct-current path between the KPAW cathode (tungsten electrode) and the GMAW anode (welding wire), the ionized plasma arc was extended to the GMA side, causing an expansion of the GMA. The current at the GMAW droplet was diverged; thus, the Lorentz force promoted a more stable one pulse one droplet metal transfer mode compared with that of GMAW-P. The strong backward flow from the keyhole was suppressed because of the pull-push flow pattern on the top surface of the weld pool be-tween the two arcs. As the heat and molten metal in the weld pool were transported from the region near the GMA (high temperature) to the region near the plasma arc (low temperature), the weld pool temperature decreased.

Pig blood is an important by‐product of the meat industry, which has not been fully utilized. In this study, Pig Blood Cells (PBC) were hydrolyzed by Alcalase and followed with simulated Gastrointestinal (GI) digestion to generate bioactive peptides. The antioxidant properties and the intestinal epithelial cells permeabilities of di‐/tripeptides from PBC Hydrolysates (PBCH) were investigated. PBCH showed higher 1,1‐diphenyl‐2‐picrylhydrazy and 2,2′‐Azino‐bis(3‐ethylbenzothiazoline‐6‐sulphonic acid) radical scavenging activities than PBC, although the activities were weakened by GI digestion. Besides, both PBCH and GI digested PBCH (PBCH‐GI) significantly improved cell viability and suppressed the production of reactive oxygen species under oxidative stress conditions in Caco‐2 cells. By using ultra performance liquid chromatography–orbitraptandem–mass spectrometry (UPLC–Orbitrap–MS/MS) technique, 5, 144, and 150 di‐/tripeptides sequences were characterized in the PBC, PBCH and PBCH‐GI groups, respectively. The transepithelial transportation revealed that the permeability of di‐/tripeptides through intestinal epithelial cells varied from 0.48% to 10.80%, and the peptides SDL, GDL, KF, FE exhibit high permeability values of 10.80%, 10.62%, 8.79% and 7.54%, respectively. These results indicate that PBCH has strong antioxidant properties and contains absorbable di‐/tripeptides, which is promising for functional food additive.
