Potentialities of Lettuce (Lactuca Sativa L.) in Hydroponics System Under Simple Nutrient Addition Program (SNAP)

The study was conducted to evaluate the potential of lettuce in a non-recirculated hydroponics system using a simple nutrient addition program (SNAP) in terms of plant height, number of leaves, length of leaves, width of leaves, and yield under screenhouse conditions. The study was conducted at the High Value Commercial Crops (HVCC) production area, DEBESMSCAT, Cabitan, Mandaon Masbate, from February 22, 2021, to March 23, 2021. The experimental design used was the CRD with four (4) treatments and three (3) replications. The study used different levels of SNAP solution. Treatment A used 25ml of SNAP A and SNAP B, Treatment B (30ml), Treatment C (35ml) and Treatment D (Control). The results of the study revealed that the application of SNAP solution to the lettuce did not have a significant effect on the length and width of lettuce leaves. However, the application of SNAP solution to the lettuce had a significant effect on the height, number of leaves, and yield. The different levels of SNAP solution had a highly significant effect on water consumption and the SNAP hydroponics system proved highly efficient in water consumption during the summer season inside the screenhouse under DEBESMSCAT, Masbate condition

Edible Bell Under Shade: The Phenological Characterization of Bell Pepper (Capsicum annum) Under Different Photoperiod

The study was conducted to evaluate the growth, inflorescence development, and yield response of the bell pepper to the different photoperiods (shading). The study was conducted from March 21 to May 15, 2021 at the DEBESMSCAT-Crop Science experimental area, Cabitan, Mandaon, and Masbate. The study used 15 experimental plots, and each plot contained 20 plants of bell pepper. The study used a total of 300 plants in 15 plots. The plant spacing was 40 cm between hills and 60 cm between rows. The study used a Randomized Complete Block Design (RCBD) with 5 treatments and 3 replications. The treatments used were different photoperiods (shading). Treatment A used shading starting from 6:00 A.M. – 9:00 A.M., Treatment B used shading from 9:00 A.M – 12:00 P.M., Treatment C used shading from 12:00 P.M – 3:00 P.M., Treatment D used shading from 3:00 P.M. – 6:00 P.M., and Treatment E (control) used no shading. The study used 10 experimental plants, randomly selected for each plot in every treatment. The data gathering started 7 days after transplanting and was conducted every 5 days. The results of the study revealed that the different photoperiods (times of shading) have no significant effect on growth in terms of plant height, number of leaves, leaf width and length, and stem diameter. Moreover, on the inflorescence development of bell peppers in terms of number of flowers, length of stalks, and size of flowers (diameter). The results on fruiting in terms of number of fruits, sizes (length and diameter), and weight also revealed that the different photoperiods have no significant effect. However, the results of the study on the number of fruits per plant and per plot revealed significant differences among each treatment

Psychosomatic problems and countermeasures in Japanese children and adolescents

In Japan there are a number of children and adolescents with emotion-related disorders including psychosomatic diseases (orthostatic dysregulation, anorexia nervosa, recurrent pains), behavior problems and school absenteeism. According to our previous report, the Japanese children had significantly higher score of physical symptoms and psychiatric complaints than did the Swedish children, and these were more strongly influenced by school-related stress than by home-related stress. To enforce countermeasures for psychosomatic problems in children, the Japanese Society of Psychosomatic Pediatrics (established in 1982) have started several new projects including multi-center psychosomatic researches and society-based activities. In this article, we present an outline of our study on mental health in Japanese children in comparison with Swedish children. Countermeasures including clinical guidelines for child psychosomatic diseases are reviewed and discussed

New Approach for Boat Motion Analysis in Rowing

In rowing, the study of the movement of the boat and of the rower in the boat is difficult. Indeed, the shell is quite narrow and fragile and it is impossible to use the classical apparatus for physiological and biomechanical analysis. For this reason, the physiological studies of rowers (cardiac and pulmonary parameters) have been more easily realised on specific and non specific ergometers (see Hagerman for an extensive review 1984): it is well known now, that rowers have exceptional aerobic possibilities and also use anaerobiosis for the start and the final part of the race (Hagerman 1984). In contrast, only a few publications deal with the movement of the boat and the rower. The velocity of the boat at different stroke rates (Martin and Bernfield 1980), the angular velocities of various articulations of the rowers (Nelson and Widule 1983) were studied by kinematic analysis. Though this technique is very useful, it does not catch the movements behind the subjects and is of no use to record physiological and mechanical parameters (Ishiko 1967). Some authors used DC recorder placed in a motor boat following the racing shell to record different parameters (Baird and Soroka 1952; Di Prampero 1971; Celentano 1974). But, this technique is not practical because of the need of a second operator to keep the cables out of the water. With the miniaturization, Ishiko proposed and used multichanneltelemetry to record the force of the rower and the acceleration of the boat (Ishiko 1967; Ishiko 1971). Schneider also used the same technique to record the force of the rower in the boat (Schneider 1978). Though this technique is excellent and powerful, it is also very expensive and quite sophisticated. Our goal was thus to take advantage of the miniaturization of the elements and to build and use a recorder and transducers that can be placed into the boat to record the acceleration of the boat and the propulsive force of the rower

Phadiatop Infant in the Diagnosis of Atopy in Children with Allergy-Like Symptoms

Background and Objective. Allergy-like symptoms such as wheezing and eczema are common in young children and an early diagnosis is important to initiate correct management. The objective of this study was to evaluate the diagnostic performance of Phadiatop Infant, an in vitro test for determination of early sensitisation to food and inhalant allergens. Patients and Methods. The study was conducted, retrospectively, using frozen sera from 122 children (median age 2.7 years) admitted to the hospital with suspected allergic symptoms. The doctor's diagnosis atopic/nonatopic was based on routinely used procedures such as clinical evaluation, SPT, total and allergen-specific IgE antibodies. The performance of Phadiatop Infant was evaluated in a blinded manner against this diagnosis. Results. Eighty-four of the 86 children classified as atopic showed a positive Phadiatop Infant test. Thirty-six were classified as nonatopic, 32 of who had a negative test. With a prevalence of atopy of 70% in this population, this gives a sensitivity of 98%, a specificity of 89%, and a positive and negative predictive value of 95% and 94%, respectively. Conclusion. The results from the present study suggest that Phadiatop Infant could be recommended as a complement to the clinical information in the differential diagnosis on IgE-mediated disease in young children with allergy-like symptoms

Characterization of Lettuce (Lactuca Sativa) in Soilless Farming System Using SNAP Solution Blended with Different Biofertilizer Extracts

The study was conducted to evaluate the characteristics of lettuce in soilless non-recirculated (hydroponic) system using Simple Nutrient Addition Program (SNAP) solution blended with different biofertilizer extracts in terms of number of leaves, width of leaves, length of leaves, plant height and yield in the greenhouse under DEBESMSCAT, Masbate, Philippine condition. The experimental design used was Complete Randomized Design (CRD) with seven (7) treatments and three (3) replications. A total of one hundred sixty-eight (168) seedlings were transplanted and arranged for treatment and replication. The study used the recommended level of SNAP solution blended with different biofertilizer extracts. Treatment A - SNAP solution and 300ml of fermented plant juice, treatment B - SNAP solution and 300ml of fermented fruit juice, treatment C - SNAP solution and 300ml Fish Amino acid, treatment D - SNAP solution and 300ml Vermi tea, treatment E - SNAP solution and 300ml cattle manure tea, treatment F - SNAP solution and 300ml chicken dung tea and treatment G - SNAP solution (control). Result of the study revealed that the application of SNAP solution blended with different bio-extract gave significant effect on the growth and yield characteristics of lettuce in terms of number of leaves, width of leaves, length of leaves, plant height and yield. The study concluded that the characteristics of lettuce were significantly affected by biofertilizer blended in SNAP solution. The results of this study the use and application of Vermi tea with SNAP solution in lettuce production is highly recommended in non-recirculated hydroponic system

Health-care cost reduction resulting from primary-care allergy testing in children in Italy

<p>Abstract</p> <p>Background</p> <p>Allergy places a considerable cost burden on society. Specific immunoglobulin E (spIgE) testing may improve the management of allergy patients. There is therefore a reason to quantify the economic consequences of the use of spIgE testing in the diagnosis of allergic conditions.</p> <p>Methods</p> <p>The expected costs of spIgE testing versus no-testing were calculated using a clinical decision model based on a prospective clinical trial performed in primary care.</p> <p>Results</p> <p>The expected costs per patient over 2 years decreased from 802 euros in the "no-test strategy" to 560 euros in the spIgE "test strategy". Cost savings persisted even after assumptions about the prevalence of allergy and the prices of medications were changed. The "test strategy" increased the percentage of patients correctly diagnosed from 54 to 87%.</p> <p>Conclusions</p> <p>spIgE testing of children with respiratory and/or skin problems in primary care in Italy reduces overall costs to society. These cost savings mostly result from a reduction in the use of medications, particularly corticosteroids. The study indicates that spIgE testing of all children with respiratory and/or skin symptoms would be a cost-effective strategy.</p
