Hevea latex production, relationship with tree growth, influence of clonal origin and Ethrel stimulation

Field: Agricultural and Biological Sciences (Life Sciences)

La croissance de l'Hevea brasiliensis, qui reflète la formation de la biomasse primaire, est en compétition directe avec la production de latex qui correspond à la synthèse de biomasse secondaire. Les travaux menés dans cette étude, portent sur 5 clones (AF 261, AVROS 2037, PB 217, GT1 et PB 235) très différents pour leurs caractéristiques de croissance et de rendement, et comprenant des arbres inexploités, des arbres exploités mais non stimulés et des arbres exploités stimulés à l'Ethrel de manière croissante jusqu'à 78 fois/an. Les résultats montrent que les productions de biomasse primaire et secondaire conduisent à une régression linéaire qui traduit la compétition entre deux fonctions synthétiques. Le coéfficient de répartition entre ces 2 fonctions dépend des clones et de leurs caractéristiques physiologiques. Pour les 5 clones, la capacité à réagir efficacement à l'intensité de stimulation est étroitement liée au sucre disponible dans les laticifères. Le contenu en phosphore inorganique du latex reflète le niveau d'activité métabolique en relation avec le rendement. Les résultats sont discutés en terme de typologie des clones, d'application au niveau industriel et de stratégie d'amélioration
Identifying degradation pathways at Sembrong Dam, Johor: insights from Sentinel-2 satellite imagery and NDVI analysis

Field: Environmental Science (Physical Sciences)

The study is to evaluate the catchment area mapping at Sembrong Dam in Johor, Malaysia and identify potential transit pathways contributing to dam water degradation while implementing targeted mitigation works. The analysis involved the surface runoff patterns and topographical/geographic data via a digital elevation model (DEM), providing insights into terrain characteristics, slope, and flow directions to hydrological dynamics that significantly contribute to water resource management. This study focuses on producing the catchment area map with satellite imagery and defining the transit pathway that potentially causes water degradation in a reservoir. The analysis uses satellite images from sentinel-2 processing to generate a detailed runoff map and DEM of the catchment area surrounding the dam. The study uses Red Bands (RED) and Near-Infrared Bands (NIR) to process sentinel satellite images to create NDVI maps. Data is uploaded as Raster data in QGIS, and NDVI calculations are performed to transform raw satellite data into an index for vegetation health. NDVI values are classified into different colour classes to visualize the condition of the study area. High NDVI values indicate higher concentrations of agriculture nutrients, potentially triggering eutrophication in watersheds through surface runoff. The study analyzed a 66.89 km2 reservoir catchment area using runoff maps. NDVI analysis showed vegetation density and plant health, with robust vegetation in the dam-surrounded region with an NDVI value of 0.8. However, due to its narrow geography and deep lakes, the northeastern region is slightly polluted and susceptible to algae growth. The study aims to improve understanding of LULC and water conditions by analyzing pollution levels using remote sensing data, DEM, and NDVI for mitigation strategies.

Supraspinal factors in human muscle fatigue: evidence for suboptimal output from the motor cortex.

Field: Neuroscience (Life Sciences)

1. Voluntary activation of elbow flexor muscles can be optimal during brief maximal voluntary contractions (MVCs), although central fatigue, a progressive decline in the ability to drive the muscle maximally, develops during sustained or repeated efforts. We stimulated the motor cortex and motor point in human subjects to investigate motor output during fatigue. 2. The increment in force (relative to the voluntary force) produced by stimulation of the motor point of biceps brachii increased during sustained isometric MVCs of the elbow flexors. Motoneuronal output became suboptimal during the contraction, i.e. central fatigue developed and accounted for a small but significant loss of maximal voluntary force. During 3 min MVCs, voluntary activation of biceps fell to an average of 90.7% from an average of > 99%. 3. The increment in force (relative to the voluntary force) produced by magnetic cortical stimulation was initially small (1.0%) but also increased during sustained MVCs to 9.8% (with a 2 min MVC). Thus, cortical output was not optimal at the time of stimulation nor were sites distal to the motor cortex already acting maximally. 4. A sphygmomanometer cuff around the upper arm blocked blood supply to brachioradialis near the end of a sustained MVC and throughout subsequent brief MVCs. Neither maximal voluntary force nor voluntary activation recovered during ischaemia after the sustained MVC. However, fatigue‐induced changes in EMG responses to magnetic cortical stimulation recovered rapidly despite maintained ischaemia. 5. In conclusion, during sustained MVCs, voluntary activation becomes less than optimal so that force can be increased by stimulation of the motor cortex or the motor nerve. Complex changes in excitability of the motor cortex also occur with fatigue, but can be dissociated from the impairment of voluntary activation. We argue that inadequate neural drive effectively ‘upstream’ of the motor cortex must be one site involved in the genesis of central fatigue.
Safety of immunization injections in Africa: not simply a problem of logistics.

Field: Health Professions (Health Sciences)

In 1995, the WHO Regional Office for Africa launched a logistics project to address the four main areas of immunization logistics: the cold chain, transport, vaccine supply and quality, and the safety of injections in the countries of the region. The impact of this logistic approach on immunization injection safety was evaluated through surveys of injection procedures and an analysis of the injection materials (e.g. sterilizable or disposable syringes) chosen by the Expanded Programme on Immunization (EPI) and those actually seen to be used. Re-use of injection materials without sterilization, accidental needle-stick injuries among health care workers, and injection-related abscesses in patients were common in countries in the WHO African Region. Few health centres used time-steam saturation-temperature (TST) indicators to check the quality of sterilization and, in many centres, the injection equipment was boiled instead of being steam sterilized. Facilities for the proper disposal of used materials were rarely present. Although the official EPI choice was to use sterilizable equipment, use of a combination of sterilizable and disposable equipment was observed in the field. Unsafe injection practices in these countries were generally due to a failure to integrate nursing practices and public awareness with injection safety issues, and an absence of the influence of EPI managers on health care service delivery. Holistic rather than logistic approaches should be adopted to achieve safe injections in immunization, in the broader context of promoting safe vaccines and safety of all injections.
Comparative performance of forage sorghum, grain sorghum, kenaf, switchgrass, and slat-fence windbarriers in reducing wind velocity

Field: Agricultural and Biological Sciences (Life Sciences)

ABSTRACT: Windbarriers used to control wind erosion may be woody or herbaceous, annual or perennial; or they can be “artificial.” To properly space windbarriers, the velocity-reduction characteristics of the windbarrier must be known. Velocity reduction curves for windbarriers of grain and forage sorghum [Sorghum bicolor (L.) Moench], kenaf (Hibiscus cannabinus L.), switchgrass (Panicum virgatum L.), and slat-fences were developed from field measurements. The number of rows in the respective windbarriers and their percent of upwind velocity (the lower the percent the better) at 10 m (32.8 ft) downwind [at 20 cm (8 in) height] were: switch-grass (one row, 39%), slat-fence (two rows, 43%), slat-fence (one row, 48%), grain sorghum (three rows, 60%), kenaf (eight rows, 69%), forage sorghum (four rows, 76%), kenaf (six rows, 78%), and kenaf (four rows, 79%). These and other presented data should be useful in designing windbarrier systems or modeling their effects on downwind velocities.
Transport of Thyroid and Steroid Hormones through the Blood-Brain Barrier of the Newborn Rabbit: Primary Role of Protein-Bound Hormone*

Field: Neuroscience (Life Sciences)

The transport of [125I]T3 [125I]T4, [3H]testosterone, and [3H]estradiol through the blood-brain barrier (BBB) of the newborn rabbit was studied with a tissue-sampling, single injection technique. The first pass extractions of T3 and T4 were 22 ± 2% and 14 ± 1%, respectively, after carotid injection of Ringer's solution (0.025% albumin). Thyronine transport was saturated and cross-competitive, but was not inhibited by a large excess of leucine, a neutral amino acid. The extraction of T3 was reduced to 7 ± 1% after injection of hormone mixed in a 10% T3- specific rabbit antiserum, and this value approximated the extraction of an extracellular space marker, such as sucrose (6 ± 1%). Therefore, antibody-bound T3 was not available for transport in vivo. Conversely, T3 bound to the plasma proteins in newborn rabbit antiserum, e.g. albumin, was transported into the brain. The concentration of plasma protein required to inhibit T3 transport 50% in vivo was 28-fold greater than the serum concentration that resulted in 50% binding of T3in vitro. The first pass extractions of testosterone and estradiol after injection of hormone in Ringer's solution were 100 ± 5% and 91 ± 5%, respectively. A 5 g/100 ml concentration of albumin bound about 95% of steroid in vitro, but resulted in only a 17–20% inhibition of testosterone or estradiol transport in vivo. Similarly, testosterone bound to the progesterone-binding globulin of pregnant guinea pig serum was also transported, although to a lesser extent than albumin-bound hormone. Conversely, testosterone bound to a specific rabbit antiserum, or testosterone or estradiol bound to the sex hormone-binding globulin in human serum was not transported into the brain. These results indicate that the mechanisms of thyroid and steroid hormone transport through the BBB of the newborn rabbit are very similar to those of the adult rat; therefore, the processes mediating BBB transport of protein-bound hormones are firmly established by at least the first 8–24 h of postnatal life.

Orderbook demand for corporate bonds

Field: Economics, Econometrics and Finance (Social Sciences)

Abstract We examine the determinants of investor demand for corporate bond offerings using novel data on the primary market orderbook size. We find that credit risk and bond market presence are significant in explaining investor demand. These effects are more pronounced during the crisis periods including the global financial crisis and eurozone crisis as well as during the postcrisis periods. Our results also highlight the size of the bond investor order depends on information asymmetry costs and the benefit of diversifications, as investor demand is lower for new issuers as well as very frequent issuers. The levels of investor demand have important economic consequences for bond issuers as high investor demand shortens the time to subsequent bond issues and potentially reduces the firm's cost of capital at issuance.

SOME PARAMETERS AFFECTING THE ACTIVITY OF MONOAMINE OXIDASE IN PURIFIED BOVINE BRAIN MITOCHONDRIA 1

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

Abstract— Some parameters affecting the activity of monoamine oxidase (MAO) in purified beef brain mitochondria were investigated, and diversities in enzyme properties were found as a function of substrate. The deamination of the biogenic amines: serotonin, dopamine, tyramine, tryptamine, phenylethylamine and two non‐physiological amines, kynuramine and m ‐iodobenzylamine, was studied. Anions in high concentrations inhibited enzyme activity with kynuramine being the substrate most affected. Among the biogenic amines, the activity with the indolalkylamines showed greater sensitivity to mono‐valent anions such as chloride than to polyvalent ions such as phosphate whereas the opposite was true with the phenylalkylamines. However, pyrophosphate ion had little or no effect on MAO activity, regardless of substrate. The inhibition of kynuramine and serotonin deamination was non‐competitive but mixed competitive inhibition was found with tyramine and phenylethylamine. The activity of MAO was markedly affected by pH, and it had been previously reported that the substrates showed different pH optima in their oxidation. The effect of pH on activity has been attributed in part to changes in the ionization of the substrate and the hypothesis that the true substrate is the non‐protonated amine. This was reflected in kinetic studies showing high substrate inhibition with increased pH. It was calculated that phenylethylamine would have the highest percentage of un‐ionized amine at pH 8.2 and 9.1. At these pHs, there was more pronounced inhibition with high substrate concentrations of phenylethylamine than with the other substrates. In contrast, there was little inhibition with high substrate concentrations of tyramine which was the most ionizable of the substrates tested. When K m values obtained at pH 7.4, 8.2 and 9.1 were corrected for ionization of the substrate, the corrected K m was lowest at pH 7.4 for all substrates. Less than 50% of MAO activity was lost when beef brain mitochondria was heated at 50°C for 20 min. However, there was only a slight variation with substrate in the thermal inactivation experiments. It is concluded that the mitochondrial membrane environment surrounding the enzyme imposes certain restrictions on the enzymatic activity with respect to the different substrates which, in turn, are also affected by such parameters as pH and ions. The results are discussed in terms of the relationship of these factors to the question of enzyme multiplicity.
On the Circumferential Rupture of a Head-Sheave Rim

Field: Engineering (Physical Sciences)

To investigate a cause of the circumferential rupture at the lower end of the rim-wing of a head sheave, a model experiment was carried out, and it was observed that both the upper ends of the rim-wings were opened outward. According to this observation, an approximate analysis has been done. In this analysis, a part of the rim between two arms was assumed as an uniformly loaded curved beam with two fixed ends, and the relative contraction between the upper end of the rim-wing and the lower end was calculated. Furthermore, the rim-wing of this part was assumed as an uniformly loaded rectangular-plate with one fixed side and one free side, simply supported along the other two opposite sides. Then, by equating the contraction along the chord subtending the deflected free side of the plate to the former contraction and calculating the corresponding uniform load on the plate to the contraction, the radial stress at the lower end of the rim-wing and the outward deflection of the upper end of the rim-wing were obtained.The results of this analysis well agreed with those of the experiment and predicted the same condition of the rupture of a full-size sheave as that obtained by the experiment. Thus, the above analytical consideration proved to be important for the design of such a head-sheave.
Ideal carrier multiplication in monolayer MoSe2

Field: Materials Science (Physical Sciences)

Abstract

Carrier multiplication (CM), the process of generating multiple charge carriers from a single photon, offers an opportunity to exceed the Shockley-Queisser limit for solar cell efficiency. However, realizing significant efficiency improvements through CM in traditional semiconductors has proven challenging, necessitating fine-tuning of material properties. In this study, we utilize ultrafast transient absorption spectroscopy to demonstrate that monolayer MoSe2 can achieve the theoretical maximum CM efficiency allowed by energy-momentum conservation laws. By resolving the spatiotemporal dynamics of hot carriers and employing first-principles calculations, we identify the cornerstone of optimal CM in MoSe2: superior hot carrier dynamics characterized by effective suppression of energy loss via carrier-lattice scattering, and the availability of abundant CM pathways facilitated by 2Eg band nesting. Our findings position monolayer MoSe2 as an exceptional candidate for advanced optoelectronic applications and as a pivotal platform for exploring quantum hot carrier dynamics.
Characteristics of coaxial-annular through-silicon-via in microwave field

Field: Engineering (Physical Sciences)

The characteristics of coaxial-annular through-silicon via (CA-TSV) are investigated in microwave field. The analytical models of the reflection coefficient and insertion loss of CA-TSV are developed according to the microwave theory, and are verified by HFSS based on finite element analysis (FEA). And then the insertion loss of CA-TSV is compared with that of cylindrical TSV (C-TSV). It is shown that CA-TSV offers superior signal integrity within the range from 0 to 35GHz, as compared with C-TSV.
Ultrastructural changes in the root tip and leaf cells of Lens culinaris treated with fluazifop-p-butyl

Field: Agricultural and Biological Sciences (Life Sciences)

In this study, ultrastructural changes in root tip cells and leaf cells of lentil plants treated with 4 different concentrations (0.25%, 0.5%, 1%, and 1.5%) of the herbicide fluazifop-p-butyl (FPB) were determined. The experiments were performed with light and transmission electron microscopy (TEM) and the chlorophyll content of the leaves was determined using spectrophotometric methods. The effect of FPB included alterations in cell walls, nuclei, plastids, cuticle, and epidermis. The obtained results indicate that the herbicide FPB has the ability to cause different kinds of abnormalities in various cell organelles, especially the cell walls in root tips. The effect of FPB was not limited only to the anatomy and plastid ultrastructure of the leaf, but the chlorophyll content was also affected.
Invasive Carcinomas of the Urinary Bladder: Evaluation of Tunica Muscularis Mucosae Involvement

Field: Medicine (Health Sciences)

Awareness of the existence of a tunica muscularis mucosae in the urinary bladder complicates the assessment of muscle invasive carcinomas on bladder biopsy. Sixty cystectomy specimens and select bladder biopsies were reviewed to analyze this problem. The patterns of development of the tunica muscularis mucosae were categorized as continuous, interrupted, scattered, or absent. Most bladders demonstrated several patterns of development rather than a uniform appearance. The most frequently observed pattern was that of scattered smooth muscle fibers seen in 33 of 40 (82.5%) cases. The rarity of carcinomatous invasion limited to the tunica muscularis mucosae is emphasized. The authors conclude that the potential for overstaging bladder carcinomas because of misinterpretation of this structure is small.
