The Propagation of Guavas from Stem Cuttings
Authors: Pennock W. , Maldonado G.
Published: October 2020

1. A highly successful propagation method is described by which hundreds of side-sprouts are first induced on the parent guava tree. These are later cut and rooted under alternatmg mist, with leaves attached. By using this method it is possible to produce from 500 to 1,000 guava plants from a single 3-year-old tree within 10 months. 2. An experiment is also described and discussed which showed that different rooting media, such as coarse sand and very fine gravel, with Coco-peat, fir bark, Vermiculite, Perlite, and Mexifern, had no appreciable effect on rooting. But treatment with a relatively high concentration, 200 p.p.m., of indolebutyric acid improved and accelerated rooting markedly. Rooting was still further improved if 2 percent of sugar was combined with the indolebutyric acid treatment. 3. The high susceptibility of cuttings under mist to anthracnose disease is mentioned and the usual course of the disease described. Recommendations are suggested for reducing the incidence of this disease.

A new species of plant parasitic nematode, Belonolaimus lineatus, was found associated with declining sugarcane in Isabela, P.R. This species is mainly characterized by the presence of four incisures in the lateral fields and longitudinal striae on the neck region. A posterior circle of eight labial papillae is illustrated, the first report of such structures in the genus Belonolaimus.
Host-Range, Distribution, and Bibliography of the Reniform Nematode, Rotylenchulus reniformis, with Special Reference to Puerto Rico
Authors: Ayala Alejandro , Ramírez Carmen T.
Published: October 2020

The reniform nematode which comprises five described and several undescribed species has been recognized as a dangerous plant parasite. It is undoubtedly one of the most common nematode types in our soils and its populations are usually very high. It has been found associated with most of our agricultural crops including pineapple, coffee, pigeonpea, tobacco, sugarcane, ornamentals, and vegetables. Increasing interest in the study of this parasite has suggested the existence of several other species which still remain undescribed. In Puerto Rico, it is now evident that several species are present. This statement is based on differences observed in relation to morphological and pathogenic characteristics among different populations. A list of 201 different host plants from 15 countries, including Puerto Rico and Caja de Muertos, an adjacent Island south of Puerto Rico, is given. Most of them are the result of field observations, but in many cases the susceptibility of the host has been corroborated on greenhouse inoculation trials. Eighty-nine host plants were found in Puerto Rico, 15 of which are new hosts to Rotylenchulus spp., and 74 to R. reniformis. Differences in degrees of susceptibility have been recognized, pigeonpea being the most susceptible, and ornamental crotalaria only a carrier. In Puerto Rico, the nematode has been located in 40 localities in some of which several plants have been found to be hosts. Humidity, elevation, temperature, and soil pH do not seem to be limiting factors in relation to the occurrence and distribution of the nematode. It occurs more in loamic soils but clay or sandy soils with little organic matter harbor large numbers if a suitable host plant is present. A general list of publications regarding this nematode citing 89 papers is also included.

Authors: Rodríguez Saulo J. , Bosque-Lugo R. , Pérez-Pérez R. , Rodríguez-Cabrera A.
Published: October 2020

A set of four experiments with increasing levels of the three main plant nutrients and liming were established in two lateritic soils at two locations in the coffee-growing area of Puerto Rico. Two coffee cultivars were used in the experiments. The results obtained can be summarized as follows: 1. Nitrogen levels significantly affected coffee yields of the Puerto Rico cultivar in a Catalina clay at Maricao grown under shade. 2. Phosphorus and potassium did not significantly affect the yields of these coffee cultivars at the two locations. 3. Liming did not significantly affect the yields.
The Biosynthesis of Sucrose in Sugarcane
Authors: Alexander Alex G.
Published: October 2020

Sucrose is formed from glucose-1-phosphate and fructose in the presence of tissue homogenates or undialyzed crude extracts from leaves of sugarcane. Optimum pH for the reaction is 8, although sucrose is formed readily from pH 7 to 9. Optimum concentrations of both glucose-1-phosphate and fructose lie in the area of 6 µmoles per milliliter of digest. Small quantities of sucrose are formed when either of the hexoses is added in the absence of the other. The reaction is stimulated by UTP, indicating that the formation of UDPG, and consequently the enzyme UDPG-fructose transglycosylase, is involved in sucrose production. UMP likewise stimulates the production of sucrose when added with ATP. DPN in cystein solution promotes the reaction in the presence of UDPG and ATP. There is no conclusive evidence that Mg, ATP, and DPN are required for sucrose production when added individually. ATP appears to promote glycolysis and retard sucrose formation under certain conditions, and promote sucrose production at other times by phosphorylative reactions.

Authors: Jackson George C. , Bauzá Salas Juan
Published: October 2020

It was found during investigations conducted with the tropical nut tree, Lecythis elliptica H.B.K., that the flowers of this plant are allogamous and not autogamous. The plant is entomophilous and not anemophilous. A survey of the insect fauna of this plant indicates that no less than 43 species representing 36 families of 10 orders frequent it during the blooming season. Observations also indicate that the primary pollinating insects are the female carpenter bee, Xylocopa brasilianorum (L.), and also females of the white grub-parasite, Campsomeris trifasciata (F.).
Behavior of Enzymes Governing Starch- and Sucrose-Forming Pathways in Two Sugarcane Varieties Supplied with Variable Nitrate and Phosphate in Sand Culture
Authors: Alexander Alex G.
Published: October 2020

In order to test the hypothesis that starch formation and metabolism is of importance to the sucrose-forming potential of cane, a series of 4-week-old plants was subjected to treatments designed to cause wide fluctuations in the enzyme starch phosphorylase. Treatments included high and low nitrate to vary acidity, high and low phosphate to vary the ratio of H3PO4 to glucose-1-phosphate, and two varieties (Uba and M.336) with distinct reputations for producing starch and sucrose, respectively. Treatments were supplied in 2 X 2 X 2 factorial combination. Sugar and enzyme assays were conducted with leaf and meristem samples harvested after 8 weeks of treatment. Sugars included total ketose, total reducing sugars, sucrose, fructose, and glucose. Enzymes included sucrose phosphorylase, starch phosphorylase, invertase, amylase, hexokinase, peroxidase, polyphenol oxidase, and a series of acid phosphatases hydrolyzing ß-glycerophosphate, glucose-1-phosphate, glucose-6-phosphate, fructoses- phosphate, 3-phosphoglyceric acid, ATP, and ADP.
Effect of Fertilizers on the Sapogenin Yields of Dioscorea composita in Puerto Rico
Authors: Cruzado Héctor J. , Delpín Herminio , Martin Franklin W.
Published: October 2020

Seedlings of Dioscorea composita were treated with various combinations of ammonium sulfate, superphosphate, and potassium sulfate over a 3-year period. The tubers of the resulting plantings were tested for sapogenin content. Complete fertilization increased the sapogenin yields significantly as compared with an untreated control. Incomplete combinations or single-nutrient treatments did not significantly increase yields and, in some cases, decreased them. Yield increases were associated with increased fresh and dry weight. Although no significant effects of fertility on percentage of sapogenin were found, tubers in unfertilized plots contained the highest sapogenin in percentage.
Parasitic Natural Regulatory Agents Attacking Musca domestica L. in Puerto Rico
Authors: Legner E. F. , Bay E. C. , McCoy C. W.
Published: October 2020

Immature stages of Musca domestica L. were sampled in Puerto Rico during 1903 for the purpose of securing parasitic material for use in biological control work in California. Six hymenopterous parasites were discovered in more or less stable breeding sites. One undescribed species of Diapriidae, Trichopria sp., and five Pteromalidae, Spalangia endius Walker, Spalangia nigroaenea Curtis, Spalangia slomoxysiae Girault, Muscidifurax raptor Girault and Sanders, and Pachycrepoideus vindemmiae (Rond.) were involved. Parasitization at any given collection site ranged from 1.4 to 25 percent of viable pupae. The Central and West Central Sections of the Island showed highest parasite activity. The role of predators other than ants was thought to be of prime importance in natural control of the more advanced immature stages of houseflies.
Salinity Effects on Sugarcane Germination, Growth, and Root Development
Authors: Liu Lii-Jang
Published: October 2020

A study was made to determine the salt resistance of 10 sugarcane varieties, P.R. 980, P.R. 1000, P.R. 1013, P.R. 1016, P.R. 1017, P.R. 1028, P.R. 1048, P.R. 1059, M. 336 and Co. 419, in the greenhouse, where canes were established in soil initially nonsaline and irrigated with 0, 4,000-, and 8,000-p.p.m. solutions of sodium chloride at 2- to 3-day intervals. Among the three criteria, percentage of germination, rate of stem growth, and dry weight of root, used for evaluating varietal resistance to soil salinity, the rate of stem growth appeared to be the most significant. Based on the effect of the salt conductivity on the soil on the daily average stem growth, P.R. 1028 was the most resistant variety to soil salinity and P.R. 1000 was the most susceptible. P.R. 1028 showed no appreciable effect of salt concentration on stem growth, nor did it show any signs of salt damage on root development, when grown in the soil with a salt conductivity as high as 20 millimhos/cm., while P.R. 1000 had salt injuries when grown in the soil with a salt conductivity that exceeded 5.4 millimhos/cm.
Modelación econométrica de la eco-eficiencia en las empresas eléctricas de costa rica utilizando smart grid
Authors: Espinosa Porras Rodrigo
Published: October 2020

La eco-eficiencia expresa la eficiencia con la cual los recursos ecológicos se utilizan para satisfacer las necesidades humanas. Se considera como el promedio de un output dividido por un input; el primero es el valor de los productos y servicios producidos por una empresa, sector, o economía en su conjunto, y el segundo, la suma de las presiones ambientales generadas por la empresa, sector, o economía. La eco-eficiencia se mide dependiendo de la tipificación de indicadores de inputs y outputs, para ello se estableció una modelación econométrica, basada en la teoría macroeconómica de Harrod-Domar, que expresa las condiciones indispensables en una economía capitalista o de mercado, para generar el volumen de demanda global necesario y, así, permitir el desarrollo sostenido y equilibrado, sin abandonar el sistema keynesiano. Este modelo considera la capacidad productiva como una variable a lo largo del tiempo y establece que un diferencial de inversión es igual al diferencial del ahorro. En este artículo, se estudia el comportamiento del modelo de Harrod-Domar para determinar una ecuación econométrica básica que, proporcione una mejora en la curva de eco-eficiencia aplicada a las empresas eléctricas de Costa Rica. La curva de la mejora en tecnología ambiental pretende demostrar teóricamente que existe un crecimiento económico, al obtener una disminución del porcentaje de gastos u outputs en contra del ambiente, con la implementación de tecnologías de smart grid.

Dyeing of Silk Fabric with Soaked Phaseolus Vulgaris (Red kidney bean) Extract
Authors: Debjit Biswas, Goutam Bar
Published: October 2020

With the rising awareness of sustainability, eco-friendly dyes are preferred over synthetic dyes and
chemicals. In our day-to-day life, many natural ingredients have colorant substances but are discarded
without efficient use. Similarly, the seeds of Phaseolus vulgaris (Red Kidney Beans) release colorant
substances when soaked in water or boiled, but the water is drained out or discarded. The present work
aimed to utilize the above extract in a sustainable way. So, an attempt is made to dye the silk fabric with the
colorant extract with various mordants at different temperatures. The colorant was extracted by soaking Red
Kidney Beans for 3 hours and further boiling it for 20 minutes at 100ºC. Degummed and bleached Mulberry
silk fabric was dyed with the colorant extract at 90-95ºC and pH [3, 3.5, 4, 4.5, 5, 5.5] for 45 minutes. Dyed
fabric samples were tested for color strength using color i7 Spectrophotometer. Also, the dyed fabric samples
were tested for different color fastness properties (colourfastness to washing, water, rubbing, light etc.) and
mechanical properties (thickness, bending length, flexural rigidity, crease recovery). Satisfactory results were
found. Thus, the implications of the research show a promising future for dying of silk fabric with a
sustainable approach.
Innovative Approach in the Use of Traditional Aangi of Haryana
Authors: Dr. Parul Gill and Dr. Saroj S. Jeet Singh
Published: October 2020

Traditional choliof Haryana,locally known as aangi,is rare to be seen in today’s time. This upper garment
was worn by women before the adoption of kurta. It was tied at back with two pairs of strings and worn by
teaming with daaman. It was usually stitched by using ten to twelve pieces of fabric. Aangis were usually
multicolored as these were made from various leftover fabric pieces available at home. That is why they
sometimes lacked any symmetry of colour. These different pieces were joined together by finishing the seams
with magji, rick-rack, gotta or embroidery to give it a unified look. A lot oftime was spent in preparation and
decoration of this attire. Aangi was a highly intricate garment depicting the talent of women in this craft. The
present study was conducted to assess the market potential of this traditional choli of Haryana in
thismodern era.For this purposeanaangiblouse was constructed by the researcher in which constructional
features of the traditional aangiwere incorporated. Cotton blend fabrics of yellow, red and blue colours were
used as base material while herring bone stitch and mirrors were used for embellishmentas per experts’
suggestions. The aangiblousewas assessed for marketability by 200 respondents including Indian as well
as foreign visitors and stall owners/exporters in the International Trade Fair, Delhi. Acceptability of
aangiblouse was found to be excellent on all parameters i.e., traditional value (WMS 3.89), aesthetic appeal
(WMS 3.75), workmanship (WMS 3.69), colour combination (WMS 3.67), utility (WMS 3.64) uniqueness (WMS
3.57) and fabric (WMS 3.41). On an average acceptability was found to be excellent.This aangiblouse can be
teamed with a transparent saree for creating a unique style statement.Some respondents suggested to
modify aangi as top or to use original form of aangi under transparent top.
The Role of Long-Duration Energy Storage in Deep Decarbonization: Policy Considerations
Authors: Ratz Heidi , Robichaud Robi , Bird Lori , Hutchinson Norma
Published: October 2020

Achieving deep decarbonization in the US will require days, and potentially weeks, of energy storage to be available – but today’s technologies only provide hours of capacity. Evolving technologies, like hydrogen, will be needed for long duration storage that can extend to weeks of capacity. While the needs of our future grid are still uncertain, policymakers can and should support the evolution of long-duration, clean energy storage by encouraging technology innovation and enabling financing and procurement models that align with long-duration storage.

New Climate Federalism: Defining Federal, State, and Local Roles in a U.S. Policy Framework to Achieve Decarbonization
Authors: Bianco Nicholas , Litz Franz , Saha Devashree , Clevenger Tyler , Lashof Dan
Published: October 2020

In the U.S., the scale and urgency of the climate crisis requires that each level of government — federal, state and local — fully bring their strengths to the table. The possibility of eventual federal reengagement on climate policy puts in question the future roles of state and local governments in carrying out such policies. To take a closer look at which strengths these levels of government can leverage, WRI convened a group of thought leaders among current and former U.S. federal, state and local government officials for a recurring dialogue. Together, they laid out a vision for what climate action could look like at all levels of government and agreed upon a set of “Principles for a New Climate Federalism.” This paper sets out the context and findings of the dialogue discussions, and proposes a working federalism framework to delineate roles within a future federal climate policy.

Objectives: This study was designed to investigate the concentration of calcium level in blood of breast, artificial and mixed feeding babies. Methods: The total number of babies covered were 269 babies of different ages, however, the babies were divided into four groups, including group (I) consists of 98 male and female babies aged between (1 day -6 months), group (II) consists of 53 male and female babies aged between (7 m -12 m), group (III) consists of 59 male and female babies aged between (13 m -18 m), and group (IV) consists of 59 male and female babies aged between (19 m -2 m). Results: The mean concentration of serum blood calcium in breast feeding (9.25 mg/dL) was significantly lower (P < 0.05) than artificial feeding (9.79 mg/ dL) and mixed feeding (9.88 mg/dL). Meanwhile, the mean concentration of serum blood calcium level (8.93 mg/ dL) in babies aged between (13 m-18m) was significantly lower (p<0.05) than other aged groups. However, the effect of the babies’ gender o the concentration of calcium indicated that the serum calcium levels did not show any significant difference among males and females’ babies. Conclusion: The relationship between age type of feeding and the gender show a correlation among the factors studied, therefore, it can be concluded that the babies fed on mixed milk got a benefit regarding the levels of these minerals as their serum levels are higher than the serum levels of babies fed on breast and artificial milk.

This research started from a controversial about professional zakat of Islamic law, between pros and cons, about the legal position and the system of implementing professional zakat. Specifically there is no dalil nash (al-qur?an and hadits) that mentions professional zakat as from the types of zakat that are required, even the classical books don?t talk about this problem, so that professional zakat seen as a legal product that is Ijtihadi.

Then in this paper will discuss the controversy of professional zakat between which the group accept namely progressive scholars who consider that a new legal product can be made in the framework of responding to development, needs and benefit of the peoples. And teams that reject that is parson that a conservative outlook is seeking to protect the purity of Islamic teachings, with reject all new thoughts that are not based on are valid (clear and unequivocal). In author anliysis, the argument in favor of the profession is stronger and more convincing than the group that rejected it. The study qualitative methods that focus on an approach to literature (library research).

Abstract. We have estimated the spatial changes in NO2 levels over different regions of India during the COVID-19 lockdown (25th March–3rd May 2020) using the satellite-based tropospheric column NO2 observed by the Ozone Monitoring Instrument (OMI) and the Tropospheric Monitoring Instrument (TROPOMI), as well as surface NO2 concentrations obtained from the Central Pollution Control Board (CPCB) monitoring network. A substantial reduction in NO2 levels was observed across India during the lockdown compared to the same period during previous business-as-usual years, except for some regions that were influenced by anomalous fires in 2020. The reduction (negative change) over the urban agglomerations was substantial (∼ 20–40 %) and directly proportional to the urban size and population density. Rural regions across India also experienced lower NO2 values by ∼ 15–25 %. Localised enhancement of NO2 associated with isolated emission increase scattered across India, were also detected. Observed percentage changes in satellite and surface observations were consistent across most regions and cities, but the surface observations were subject to larger variability depending on their proximity to the local emission sources. Observations also indicate NO2 enhancements of up to ∼ 25 % during the lockdown associated with fire emissions over the north-east, and some parts of central regions. In addition, the cities located near the large fire emission sources show much smaller NO2 reduction than other urban areas as the decrease at the surface was masked by enhancement in NO2 due to the transport of the fire emissions.

Abstract. South West Western Australia (SWWA) has experienced a prolonged reduction in rainfall in recent decades, with associated reductions in regional water supply and residential and agricultural impacts. The cause of the reduction has been widely considered, but remains unclear. The relatively short length of the instrumental record limits long-term investigation. A previous proxy-based study used a statistically negative correlation between SWWA rainfall and snowfall from the Dome Summit South (DSS) ice core drilling site, Law Dome, East Antarctica and concluded that the anomaly of recent decades is unprecedented over the ∼750 year period of the study (1250–2004 CE). Here we extend the snow accumulation record to cover the period 22 BCE–2015 CE and derive a rainfall reconstruction over this extended period. This extended record confirms that the recent anomaly is unique in the period since 1250 CE and unusual over the full ∼2000 year period, with just two other earlier droughts of similar duration and intensity. The reconstruction shows that SWWA rainfall started to reduce around 1971 CE. Ensembles of climate model simulations are used to investigate the potential roles of natural variability and external climate drivers in explaining changes in SWWA rainfall. We find that anthropogenic greenhouse gases are likely to have contributed towards the SWWA rainfall drying trend after 1971 CE. However, natural variability may also have played a role in determining the timing and magnitude of the reduction in rainfall.
Seasonal discharge response to temperature-driven changes in evaporation and snow processes

Published: October 2020

Abstract. This study analyses how temperature-driven changes in evaporation and snow processes influence the discharge in large river basins. Using a distributed efficient hydrological model at high spatio-temporal resolution, we investigate the relative contribution of snow and evaporation. Comparing two 10-year periods (1980s and 2010s) in the Rhine allowed to determine the contribution of changes in snow, evaporation and precipitation to the discharge. Around half of the observed changes could be explained by the changes induced by snow (11 %), evaporation (19 %) and precipitation (18 %), while 52 % was driven by a combination of these variables. Increased temperature scenarios show that seasonal changes in snow-dynamics could offset a fairly constant negative change in relative runoff induced by evaporation, but not during the melt season. This study shows how the combined effect of temperature-driven changes affect discharge. With many basins around the world depending on meltwater, correct understanding of these changes is vital.

Abstract. Research vessels equipped with fibreoptic and copper cored coaxial cables support the live onboard inspection of high-bandwidth marine data in real-time. This allows towed still image and video sleds to be equipped with latest generation higher resolution digital camera systems and additional sensors. During RV Polarstern expedition PS118 in February–April 2019, the recently developed Ocean Floor Observation and Bathymetry System (OFOBS) of the Alfred Wegener Institute was used to collect still and video image data from the seafloor at a total of 11 ice covered locations in the northern Weddell Sea and Powell Basin. Still images of 26 megapixel resolution and HD quality video data were recorded throughout each deployment. In addition to downward facing video and still image cameras, OFOBS also mounted sidescan and forward-facing acoustic systems, which facilitated safe deployment in areas of high topographic complexity, such as above the steep flanks of the Powell Basin and the rapidly shallowing, iceberg scoured Nachtigaller Shoal. To localise collected data, the OFOBS system was equipped with a POSIDONIA transponder for Ultra Short Baseline triangulation of OFOBS positions.

Abstract. CITYZER develops new digital services and products to
support decision-making processes related to weather and air quality in
cities. This includes, for example, early warnings and forecasts (0–24 h), which
allow for avoiding weather-related accidents, mitigate human distress and
costs from weather-related damage and bad air quality, and generally improve
the resilience and safety of the society. The project takes advantage of the
latest scientific know-how and directly exploits the expertise obtained from
earlier projects. Central to the project is the Observation Network Manager
NM10 developed by Vaisala, on which CITYZER defines and builds new
commercial services and connects new sensor networks, for example, for air quality
measurements, as well as the ENFUSER local-scale air quality modelling
system developed by the Finnish Meteorological Institute, for real-time air
quality forecasts and nowcasts.
