In this frontline, we use bimetal switches to provide inputs in an electrical AND logic gate. These switches can be obtained from the pre-heat starters of fluorescent lamps, by safely removing the glass enclosure. They may be activated by small open flames. This frontline has a historical aspect because fluorescent lamps, together with pre-heat starters, are now being replaced by compact fluorescent, halogen, and LED lamps. © 2016 IOP Publishing Ltd.

This study was conducted to evaluate the performance of six stem taper models on four tropical tree species, namely Celtis luzonica (Magabuyo), Diplodiscus paniculatus (Balobo), Parashorea malaanonan (Bagtikan), and Swietenia macrophylla (Mahogany) in Mount Makiling Forest Reserve (MMFR), Philippines using fit statistics and lack-of-fit statistics. Four statistical criteria were used in this study, including the standard error of estimate (SEE), coefficient of determination (R2), mean bias (Formula presented.) , and absolute mean difference (AMD). For the lack-offit statistics, SEE, (Formula presented.) and AMD were determined in different relative height classes. The results indicated that the Kozako2 stem taper model offered the best fit for the four tropical species in most statistics. The Kozako2 model also consistently provided the best performance in the lack-of-fit statistics with the best SEE, (Formula presented.) and AMD in most of the relative height classes. These stem taper equations could help forest managers and researchers better estimate the diameter of the outside bark with any given height, merchantable stem volumes and total stem volumes of standing trees belonging to the four species of the tropical forest in MMFR. © 2016, Science Press, Institute of Mountain Hazards and Environment, CAS and Springer-Verlag Berlin Heidelberg.

The Janghang smelter in Chungnam, South Korea started in 1936 was subsequently shutdown in 1989 due to heavy metal (loid) pollution concerns in the vicinity. Thus, there is a need for the soil in the area to be remediated to make it usable again especially for agricultural purposes. The present study was conducted to exploit the potential of arsenic (As)-tolerant bacteria thriving in the vicinity of the smelter-polluted soils to enhance phytoremediation of hazardous As. We studied the genetic and taxonomic diversity of 21 As-tolerant bacteria isolated from soils nearer to and away from the smelter. These isolates belonging to the genera Brevibacterium, Pseudomonas, Microbacterium, Rhodococcus, Rahnella, and Paenibacillus, could tolerate high concentrations of arsenite (As(III)) and arsenate (As(V)) with the minimum inhibitory concentration ranging from 3 to >20 mM for NaAsO2 and 140 to 310 mM NaH2AsO4 · 7H2O, respectively. All isolates exhibited As(V) reduction except Pseudomonas koreensis JS123, which exhibited both oxidation and reduction of As. Moreover, all the 21 isolates produced indole acetic acid (IAA), 13 isolates exhibited 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase activity, 12 produced siderophore, 17 solubilized phosphate, and 13 were putative nitrogen fixers under in vitro conditions. Particularly, Rhodococcus aetherivorans JS2210, P. koreensis JS2214, and Pseudomonas sp. JS238 consistently increased root length of maize in the presence of 100 and 200 μM As(V). Possible utilization of these As-tolerant plant-growth-promoting bacteria can be a potential strategy in increasing the efficiency of phytoremediation in As-polluted soils. © 2014 Springer-Verlag Berlin Heidelberg.

The author investigated attitudes of nursing students enrolled in e-Learning towards academic dishonesty. The descriptive-exploratory design was used in the conduct of the study. Respondents were randomly selected 36 junior and senior nursing students. It revealed that nursing students perceived as neutral (mean = 2.77, mean = 3.17) in taking responsibility for promoting academic integrity in e-learning. The paraphrasing a sentence from internet source without referencing it (38.89%) got the most form of cheating. Female and level four (4) nursing students revealed as the most cheaters. The reasons not to cheat, nursing students considered punishment, and education or learning (91.67%) got the highest in ranks, and simply wrong (75%) got the lowest rank. Hence, there is a need to look on how to maintain academic honesty among nursing students in and out of the university with respect to e-learning as a means of teaching-learning method. © 2014 The authors and IOS Press.

Stem volume equations (overbark) were developed, using established volume equation forms, and validated using a subset of the data collected for Pinus kesiya in Benguet province, Philippines. A total of 481 trees from Pinus kesiya stands in Benguet were measured through non-destructive sampling. The data set was randomly split into two subsets for initial model development (80% of the data set) and validation (20% of the data set). The performance of the different models was evaluated using evaluation statistics: fit index (FI), root mean square error (RMSE), bias (Ē), absolute mean difference (AMD) and coefficient of variation (CV%). The best model forms were selected for final model development using the combined data set (100%). Overall, volume models with two independent variables (DBH and total height) performed better than models with only one (DBH). In the validation of the models, it was observed that AMD of the models converged in the DBH classes with higher sample size. Furthermore, one of the best models in this study, Model 2, also performed better when compared to the general single volume equation developed for the non-dipterocarp species in regions 1, 2, 3 and the Cordillera Administrative Region (CAR) of the Philippines. The models developed in this study may assist forest managers acquire improved stem volume predictions of Pinus kesiya in the forests of Benguet, Philippines. © 2013 Copyright NISC (Pty) Ltd.

In the Philippines, strawberry is grown only in Benguet Province because of its unique climatic conditions. It has been a lucrative source of income for Benguet farmers and adds to the revenue of Benguet Province. The root lesion nematode, Pratylenchus penetrans is an economically important pest of strawberry in the area. It can cause substantial losses to strawberry growers, both by reducing vegetative plant growth and by reducing strawberry yields. The nematode has a very wide host range and hence, is not readily controlled by crop rotation. An alternative approach which growers may wish to consider trying is planting of strawberry varieties which are either resistant or tolerant to this nematode. The relative susceptibility/tolerance of six strawberry cultivars to the root lesion nematode, P. penetrans was evaluated under greenhouse and field conditions. Inoculation of 500 nematodes/pot did not significantly affect the fresh top weight, fresh root weight, and yield of strawberry cultivars Festival, Whitney, Winterdawn, Earlibrite, and Camarosa. The said cultivars had significantly higher number of nematodes recovered from the roots. On the other hand, the highest strawberry yield was recorded in cv Sweet Charlie, however, this was significantly reduced by nematode inoculation .Surprisingly, the number of nematodes recovered from the roots of this cultivar was significantly the lowest among the cultivars tested. Results of the field experiment showed that strawberry cv Sweet Charlie gave the highest marketable yield which was significantly different from the rest of the cultivars tested. This was followed by Festival, and Earlibrite. On the other hand, Camarosa and Whitney gave significantly lower yield than the above cultivars but significantly higher than Winterdawn. In terms of nematodes recovered from the roots, the highest was noted in Whitney, followed by Sweet Charlie and Earlibrite. The lowest was obtained from Camarosa, followed by Festival and Winterdawn. Based on the results of the greenhouse experiment, Festival, Whitney, Winterdawn, Earlibrite and Camarosa can be considered tolerant while Sweet Charlie was slightly susceptible to P. penetrans. However, based on the field trial, Sweet Charlie, Festival and Earlibrite were tolerant while Whitney, Camarosa and Winterdawn were slightly susceptible.

Silicon (Si) has been reported to effectively manage some pests and diseases of plants. This study was conducted to determine the effect of Si concentration, mode, and frequency of application in managing Meloidogyne incognita in cucumber. A susceptible cultivar of cucumber (cv. Cyclone) was planted in pots containing heat-sterilized soil. Three weeks after planting, the plants were inoculated with 1,000 juveniles/ pot. Uninoculated plants were provided to serve as control. Three concentrations of Si in the form of sodium metasilicate was applied on the leaves and roots alone and also on both the leaves and roots. Application was done once during the growing period and weekly until seven days before harvest. Leaf and root application of Si was found to significantly increase (p = 0.0029) the fresh top weight of inoculated and uninoculated plants. On the other hand, inoculation of root-knot nematode significantly increased the fresh root weight of cucumber which could be due to enlargement of roots or formation of galls. Interestingly, the inoculated plants gave significantly higher marketable yield than uninoculated ones. Application of Si at the rate of 200 ppm significantly increased the marketable yield compared to the higher rate of Si (400 ppm). At 200 ppm, one application of Si both on the leaves and roots significantly reduced the number of galls in inoculated plants. This was comparable to the same concentration applied continuously on the roots and at higher concentration (400 ppm) applied continuously on the leaves and on the roots. On the other hand, single root application of Si at the rate of 400 ppm gave the lowest number of eggmasses, however, it was comparable to the same Si concentration applied singly on the leaves and applied continuously both on the leaves and roots. These treatments, however, were at par with continuous application of the lower rate of Si (200 ppm) on the leaves and both leaves and roots.

Three farmer cooperators in Banooy, Buguias, Benguet used Trichoderma microbial inoculant (TMI) as a control measure against club root disease of crucifers caused by Plasmodiophora brassicae Wor., in addition to the usual farmers' practice of applying chemical pesticides. Two treatments were used: farmers' practice (FP - control) and T1 (Trichoderma inoculant). In both treatments, chicken manure (416 g m -2) and chemical fertilizers (triple 14, 205-220 g m -2) were applied; the chemical fungicide mancozeb (3.3 g m -2) and the insecticides carbaryl and flubendiamide (2.0 mL m -2) were also used. In T1, Trichoderma inoculant was applied at 0.5 g m -2 at the seedling stage, but not in FP. The test crops were Brassica oleracea capitata group (head cabbage) and B. rapa, Pekinensis group (Chinese cabbage). One farmer used less material and labor inputs in plots where Trichoderma inoculant was added; all other cultural practices were the same for both treatments. In all three farmers' fields, there was a very high incidence of the disease in the conventional plots where only chemical pesticides were used. In the conventional plots, all roots of diseased plants were clubbed - an indicator of full disease severity. In the plot treated with Trichoderma inoculant, disease incidence was reduced by 45%, indicating that only Trichoderma was able to control the disease. Roots of Trichoderma-treated infected plants showed suppression of the disease and production of new roots, allowing the continuous development of the crop and resulting in high yields. New infections were also prevented. Analyses of partial production cost and partial gross financial returns showed that Benguet farmers were losing as much as PhP 35,000 (∼ US$ 795) in 0.25-ha field per cropping due to ineffective control of the disease by chemical pesticides. The use of Trichoderma inoculant for disease control resulted in a three-fold increase in farmers' partial gross income.
