        Nueva Ecija is a landlocked province in Central Luzon region that is composed of 27 municipalities and 5 cities. It is a province that is rich with biodiversity on its north and east borders, which exhibit a shared ecosystem with the Caraballo mountain range in the north and the Sierra Madre mountain range in the east. Its main economic activity is farming where rice is the main crop. Part of the Sierra Madre mountain range traverses its towns of Bongabon, Laur, Rizal and Pantabangan where most of the locals perform agro – forestry activities as a means of generating income for their families. Due to the accumulation of farm residues as a result of intensive agro-forestry activities, mushroom pharming becomes a very viable agribusiness undertaking in the area. Our research team initiated the establishment of database by tracking the mushroom production activities in the province. Similarly, the prevailing climatic condition in the geographical area and the type of agro-forestry wastes have been tracked. Wastes as a result of intensive agro – forestry activities are being generated which the locals oftentimes burned in the field that posed hazard to the environment. In order to discourage this practice, our research team generated technologies on mushroom pharming using rice straw as the main substrate. The promotion of mushroom pharming is based on the suitability of mushroom species to grow in climatic conditions that prevail in the specific geographical area in the province. As a result of its collaborative research undertakings, the Center for Tropical Mushroom Research and Development of the Central Luzon State University in collaboration with the Laboratory of Forest Products Chemistry of Tokyo University of Agriculture and the Nikken Sohonsha Corporation encouraged the adoption of medicinal mushroom production technologies on rice straw – based formulation. With oyster mushroom (Pleurotus spp) as the most widely cultivated mushroom among the mushroom growers in the province, other ligninolytic mushrooms such as lacquered mushroom (Ganoderma) and wood ear mushroom (Auricularia spp.) are grown by the locals. Similarly, leaf – litter degrading mushrooms such as paddy straw mushroom (Volvariella volvacea) are also being cultivated in the province. However, some mushroom growers in the province adopt sawdust – based mushroom production technology which is not economically appropriate in the province due to the scarcity of its availability compared to rice straw. Majority of the mushroom growers in the province adopt the rice straw – based mushroom technology. Moreover, high value mushroom – based products other than the fresh mushrooms are already in the local market.

        Collybia reinakeana (P.) Henn used to be a wild endemic edible mushroom not until it was discovered in the mountainous area of Puncan, Carranglan, Nueva Ecija, Philippines after the great earthquake that jolted Central Luzon in 1990. It is characterized to having big fruiting bodies (about 1 foot tall) that grow in cluster. Its mycelia were rescued from the wild and the first domestication studies were conducted which lead to the generation of its production technology. It is a nutraceutical mushroom that exhibits antibacterial and anti-hypertensive properties aside from its appreciable content of both standard as well as non- standard amino acids. It also exhibits mycoparasitic habit against species of Aspergillus, Cladosporium and Fusarium. Recently, emergence of this mushroom in the different areas in the Philippines have been reported which prompted our research team to conduct geo - tracking in order to rescue its secondary mycelia in our desire to conserve this endemic species of mushroom. With our conservation efforts, we have tracked the areas where it was found growing and subsequently isolated the secondary mycelia. At present, our research team were able to collect 9 different strains from the different areas namely Bataan (1), Science City of Munoz (2), Urdaneta City (1), San Manuel, Pangasinan (1), Rosales, Pangasinan (1), Bicos, Rizal, Nueva Ecija (1), Dipaculao, Aurora (1) and Bamban, Tarlac(1).

        Teosinte, commonly known as wild species of corn, has distributed in Central and South America. It is believed that teosinte contains genes for resistance to flooding because of the climate characteristics of the collected countries. Recent studies have shown that teosinte has the ability to form adventitious roots, to develop aerenchyma tissues of teosinte, and the resistance to toxic substances under flooding soil condition. Therefore, development of corn varieties to cope with climate change and the growing corn at paddy field in Korea are required to introduce the characteristics of teosinte. However, in order to utilize teosinte resources, preconditions must be settled such as photoperiodic responsibility, physiological and ecological characteristics. Also if the preconditions are studied together with the metabolic level studies, the possibility of utilization for flooding resistant varieties will be even higher.

        We have identified 22 quasars in the AKARI far-infrared all-sky Bright Source Catalogue, using a matching radius of < 10", and excluding matches which are close to foreground extended sources or cirrus. We have confirmed a relation between quasar optical luminosity and far-infrared luminosity which was found in an earlier study. In addition, we have found that the 11 sources which are at redshift z > 1 are magnified with respect to the predicted far-infrared luminosity, and consider this may be due to gravitational lensing. If confirmed, this would provide a new way to identify lenses; if not, we may have identi ed an interesting new population of extreme starbursting quasars.

        How stable are shopping styles of women and men across cultures? To find out, the authors develop a new scale that reliably measures differences between male and female shopping styles and is stable across cultures. They develop a conceptual model and hypotheses to test whether observed differences in gender shopping styles are likely to be innate or arise from socialization. Through a survey of consumers in seven countries, they show that males and females are evolutionary predisposed to have different shopping styles. Counter to social structural theory, the observed differences in shopping style between females and males are greater in low-context cultures (higher gender equality countries) than in high-context cultures (lower gender equality countries). Empathizing—the ability to tune into another person’s thoughts and feelings—mediates shopping style more for female shoppers; systemizing—the degree to which an individual possesses spatial skills—mediates shopping style more for male shoppers. Therefore, retail segmentation between females and males appears to be of more managerial relevance than segmentation between cultures. Other managerial implications are also discussed.

        We report the characterization of a massive (mp = 3:91:4Mjup) microlensing planet (OGLE- 2015-BLG-0954Lb) orbiting an M dwarf host (M = 0:33  0:12M ) at a distance toward the Galactic bulge of 0:6+0:4 􀀀0:2 kpc, which is extremely nearby by microlensing standards. The planet-host projected separation is a?  1:2AU. The characterization was made possible by the wide- eld (4 deg2) high cadence (􀀀 = 6 hr􀀀1) monitoring of the Korea Microlensing Telescope Network (KMTNet), which had two of its three telescopes in commissioning operations at the time of the planetary anomaly. The source crossing time t = 16 min is among the shortest ever published. The high-cadence, wide- eld observations that are the hallmark of KMTNet are the only way to routinely capture such short crossings. High-cadence resolution of short caustic crossings will preferentially lead to mass and distance measurements for the lens. This is because the short crossing time typically implies a nearby lens, which enables the measurement of additional e ects (bright lens and/or microlens parallax). When combined with the measured crossing time, these e ects can yield planet/host masses and distance.

        Galaxies can be "pre-processed" in the low-density outskirts by ambient medium in the filaments or tidal interactions with other galaxies while falling into the cluster. In order to probe how early on and by which mechanisms galaxies can be affected before they enter high-density cluster environments, we are carry- ing out an atomic hydrogen (H i) imaging study of a sample of galaxies selected from three filamentary structures around the Virgo cluster. Our sample consists of 14 late-type galaxies, which are potentially interacting with their surroundings. The Hi observations have been done using the Westerbork Synthesis Radio Telescope, the Giant Metrewave Radio Telescope, and the Jansky Very Large Array with column density sensitivity of ≈ 3-5 X 1019 cm-2 in 3σ per channel, which is low enough to detect faint Hi features in the outer disks of galaxies. In this work, we present the Hi data of two galaxies that were observed with GMRT. We examine the Hi morphology and kinematics to find the evidence for gas-gas and/or tidal interactions, and discuss which mechanism(s) could be responsible for pre-processing in these cases.
