Exchange Rate Volatility and Its Effect on Trade Export Performance in Kenya

The relationship between exchange rate volatility and economic growth has received relatively little attention from both theoretical and empirical perspectives. This is because, the exchange rate is considered as nominal variable and not related to the long‐term real growth performance. Kenya has faced massive blows like the terms of trade becoming worse mainly due to fluctuation in internal product prices, oil prices and fluctuation in a flow of capital which have led to challenges in microeconomic management policy. Empirical evidence offers mixed findings regarding the impact of exchange rate volatility on growth. It argued that pegged regimes increases investment and volatility of growth and employment but reduces productivity growth and inflation. Depreciation of Kenya’s currency implies that the incomes of their trading partners increase and will tend to import few goods, and this places Kenya’s exports at disadvantaged position in international markets. Further, exchange rate volatility in developing countries is characterized by changes in, changes in global demand for goods policies and changes prices of goods. This article investigated the exchange rate fluctuation in Kenya. investigation found that Kenya’s exchange rate has been volatile with major structural breaks in 1994 and 2012. Devaluation of Kenya’s currency implies that the incomes of their trading partners increase and will tend to import few goods, and this places Kenya’s exports at disadvantaged position in international markets. Further, exchange rate volatility in developing countries is characterized by changes in, changes in global demand for goods policies and changes prices of goods.
The Main Physicochemical Characteristics and Nutrient Composition during Fruit Ripening of Stauntonia Obovatifoliola Subsp. Urophylla (Lardizabalaceae)

Stauntonia obovatifoliola Hayata subsp. urophylla is a novel edible and healthy fruit in China, commonly known as “Jiuyuehuang” (September yellow). The fully ripe fruit of S. obovatifoliola subsp. urophylla has a soft fruit pulp texture, golden flesh, and sweet flavor which is very popular with the locals. In this paper, we have investigated the fruit appearance quality, physiochemical quality, and nutritional quality of S. obovatifoliola subsp. urophylla that was harvested at six stages (S1: 60 DAFB, S2: 90 DAFB, S3: 130 DAFB, S4: 160 DAFB, S5: 190 DAFB, S6: 205 DAFB). An increase in fruit size (including single fruit weight, fruit length, and fruit diameter) was related to the ripeness stage of fruit development. The total soluble solids, firmness, dry matter, sugar and starch showed remarkable changes as the fruit approached ripening (S5–S6 stage). The main sugar components in the fruit were fructose, glucose, and maltose. The contents of fructose, glucose, and total sugars in S. obovatifoliola subsp. urophylla fruit progressively increased from the S1 to the S6 stage while increasing sharply from the S4 to the S5 stage. As for the content of maltose and starch, they both showed an increasing trend from the S1 to the S4 stage but decreased sharply at the S5 stage. The vitamin B, vitamin C, total phenolics, total flavonoids, and amino acid levels showed an overall downward trend during fruit development. To our knowledge, this is the first study to compare the phytochemical characteristics, nutrient composition, and antioxidant content during the different fruit development stages. The results of this study may provide a scientific basis for clarifying the growth and development characteristics of S. obovatifoliola subsp. urophylla fruit and the further utilization of these excellent medicinal and edible germplasm resources.
Algebraic growth of disturbances in a laminar boundary layer

The temporal evolution of small three‐dimensional disturbances with a large streamwise scale in viscous, parallel, semi‐bounded flows is studied. In the limit of the initial disturbance being independent of the streamwise coordinate, the vertical velocity component consists solely of a continuous spectrum part. Tollmien–Schlichting waves do not appear in this special case. The streamwise perturbation velocity is obtained by solving a forced initial value problem. While the vertical velocity remains constant for small times, the streamwise perturbation velocity exhibits a linear growth due to the forcing. Eventually, viscous dissipation becomes dominant and the disturbance decays. Asymptotic solutions valid for small and large times are presented. The relation of these results to the longitudinal streaky structure found in many shear flows is discussed.
Sustainable Development Approaches through Wooden Adhesive Joints Design

Over recent decades, the need to comply with environmental standards has become a concern in many industrial sectors. As a result, manufacturers have increased their use of eco-friendly, recycled, recyclable, and, overall, more sustainable materials and industrial techniques. One technique highly dependent on petroleum-based products, and at the edge of a paradigm change, is adhesive bonding. Adhesive bonding is often used to join composite materials and depends upon an adhesive to achieve the connection. However, the matrices of the composite materials and the adhesives used, as well as, in some cases, the composite fibres, are manufactured from petrochemical products. Efforts to use natural composites and adhesives are therefore ongoing. One composite that has proven to be promising is wood due to its high strength and stiffness (particularly when it is densified), formability, and durability. However, wood must be very carefully characterised since its properties can be variable, depending on the slope of the grains, irregularities (such as knots, shakes, or splits), and on the location and climate of each individual tree. Therefore, in addition to neat wood, wood composites may also be a promising option to increase sustainability, with more predictable properties. To bond wood or wooden composite substrates, bio-adhesives can be considered. These adhesives are now formulated with increasingly enhanced mechanical properties and are becoming promising alternatives at the structural application level. In this paper, wooden adhesive joints are surveyed considering bio-adhesives and wood-based substrates, taking into consideration the recent approaches to improve these base materials, accurately characterise them, and implement them in adhesive joints.
The Effect of Indigo (Indigofera tinctoria L.) Waste on Growth Performance, Digestibility, Rumen Fermentation, Hematology and Immune Response in Growing Beef Cattle

Simple Summary Indigo waste is a by-product of the processing of natural indigo dye. Indigo waste could be utilized as a protein source in ruminant rations, which would reduce the cost of feed. We evaluated the effects of the inclusion of indigo waste in concentrate diets on the feed utilization, rumen fermentation, hematology, immune function and growth performance of growing beef cattle. The present findings suggest that the inclusion of indigo waste at low levels in concentrate diets maintains feed intake, digestibility, rumen fermentation or growth performance in growing beef cattle without affecting hematology or immune function. Abstract This experiment was conducted to assess the effect of indigo waste on the feed intake, digestibility, rumen fermentation, hematology, immune response and growth performance in growing beef cattle. Twenty crossbred beef cattle with an initial body weight (BW) of 145 ± 11 kg were fed four levels of indigo waste for 90 days in a trial. Additions of indigo waste at 0%, 10%, 20% and 30% in a concentrate diet using a completely randomized design (CRD). Cattle were fed concentrate at 1.8% BW, with rice straw fed ad libitum. The concentrate intake decreased linearly (p = 0.01) with the addition of indigo waste. The supplementation with indigo waste reduced dry matter (DM) and organic matter (OM) digestibility cubically (p = 0.03 and p = 0.02, respectively), while increasing neutral detergent fiber (NDF) digestibility cubically (p = 0.02). The final BW of beef cattle decreased linearly (p = 0.03) with the addition of indigo waste. The inclusion of indigo waste decreased the average daily gain (ADG) and gain-to-feed ratio (G:F) linearly (p < 0.01) from 0 to 90 days. The nutrient digestibility, ADG and G:F of beef cattle fed 10% indigo waste in the diet was similar when compared with the control (0% indigo waste). The ruminal pH, ammonia-nitrogen (NH3-N) and total volatile fatty acid (VFA) concentrations were similar among treatments (p > 0.05). The proportion of acetate increased linearly (p < 0.01) but propionate decreased linearly (p < 0.01), resulting in an increase in the acetate to propionate ratio (p < 0.01) when cattle were fed with indigo waste supplementation. Increasing indigo waste levels did not influence blood urea nitrogen (BUN) levels, hematological parameters or immune responses (IgA, IgM and IgG) (p > 0.05). In conclusion, the inclusion of indigo waste at 10% in a concentrate diet did not have a negative effect on feed intake, nutrient digestibility, rumen fermentation, hematology, immune function or growth performance in growing beef cattle.
Caracterización del virus de la diarrea viral bovino subtipo 1b aislado de un caso de la enfermedad de las mucosas

This report describes a fatal case of mucosal disease in a two-year-old bull. For causal agent detection, scab, whole blood, and feces samples were tested by RT-PCR, PCR, ELISA, and viral isolation. RT-PCR positive amplification was obtained in blood samples for bovine viral diarrhea virus (BVDV). Viral isolation from the scab samples confirmed BVDV as the causative agent of the clinical manifestations. Subsequently, genetic characterization based on phylogenetic analysis of three partial sequences revealed the presence of BVDV subgenotype 1b in analyzed samples. Due to the development of clinical manifestation named mucosal disease, these findings suggest the detection of BVDV persistently infected (PI) bull; therefore, these results demonstrate the importance of establishing BVDV control programs that rely on testing the presence of PI in cattle from Mexico.
Frequency of Correct Fetal Weight Estimation by Clinical and Ultrasound Methods in Pregnant Women

Objective: To determine the frequency of correct fetal weight estimation by clinical and ultrasound methods in pregnant women. Study Design: A cross-sectional study. Place and Duration: Department of Obstetrics and Gynaecology, Nishtar Hospital Multan, From February 2021 to July 2022. Methodology: A total of 383 women with singleton pregnancy, gestational age between 37 to 40 weeks and who underwent labor induction or elective cesarean section were included. Fetal weight estimation was done by clinical and ultrasound methods in pregnant women. Following delivery, “actual birth weight” of neonate was measured and data recorded in the shape of correct fetal weight estimation by both studied methods. Results: In a total of 383 women, the mean age was 29.50±2.22 years ranging between 18-35 years while the mean gestational age was 38.09±0.91 weeks. The mean mother’s weight was 70.19±10.56 kg, mean clinical weight estimation 3127.03±561.38 grams, mean ultrasound weight estimation 3137.25±658.05 grams and mean actual weight was 3157.63±648.33 grams. Correct clinical weight estimation was reported in 49.6% cases while correct ultrasound weight estimation was noted in 80.9%. Practical Implications: Accuracy in fetal weight estimation can be achieved by applying Dare’s method in the clinical setting. Conclusion: Fetal weight estimation adopting Dare's formula was found to be comparable to ultrasound estimation for the prediction of actual birth weight within 10%. Keywords: Fetal weight, gestational age, singleton, ultrasound.
Study the Raman Spectra and Dielectric Properties of Hexagonal BaTi1-xGaxO3 Ceramics

A series of polycrystalline Ga-doped Barium titanate (BaTi1-xGaxO3) were synthesized for the studies on the dopant-concentration dependence of Raman spectra and dielectric properties. The Qx f value of Ga-doping samples increases up to about 20% of Ga concentration, but the dielectric constant (K-value) decreases while the A1g phonon mode (636 cm−1) experiences an increasing red-shift. The phonon mode becomes soft with Ga-ion increasing, and the FWHM of Raman peak increases with Ga-ion increasing until tetragonal structure appeared. The effective ionic weight, ionic radii and Coulomb interaction are important influences, which induce the chemical pressure and reduce the excess charge in Ti-site in the Ga-doping h-BaTiO3 system. The relation between Raman mode shifter and K-value, and the correlation of the Qx f value and the FWHM of related phonon vibrations have been reported and examined.
Oxidation of InAlAs and Its Application to Gate Insulator of InAlAs/InGaAs Metal Oxide Semiconductor High Electron Mobility Transistor

InAlAs was oxidized by UV and ozone process. Nanometer-order thin-oxide layers were generated in proportion to the square root of the process period, although their correlation with the period is poor compared with that of InGaAs. Oxidation initially decreased photoluminescence intensity from the InAlAs surface and then gradually increased it when the process period exceeded 15 min until it reached 4 h (crystallographic-order degradation followed by recovery). Plasma nitridation of InAlAs exhibited a gradual and monotonic decrease in photoluminescence intensity. Lattice-matched InAlAs/InGaAs metal–oxide–semiconductor high electron mobility transistors were fabricated utilizing gate oxide layers which were formed by 4 h oxidation. A transconductance of 200 mS/mm was obtained using a 1.5-µm-gate-length device, in a high-forward-gate-bias region although hysteresis was observed in the current–voltage curve.

Trace Element Contents in Maize following the Application of Organic Materials to Reduce the Potential Adverse Effects of Nitrogen

The plants cultivated in loamy sand contained less iron, manganese, copper, cobalt, nickel, and zinc while containing more chromium, lead, and cadmium than in sand. This study was launched to use organic materials in the form of humic acids (HA) to reduce the potential negative effects of excessive nitrogen fertiliser (ammonium nitrate, urea, and urea and ammonium nitrate solution—UAN) application rates (160 mg N kg−1 soil) on the trace element contents in maize in two soils differing in granulometric composition. HA were applied into the soil three times during the maize vegetation: before the sowing, at the five-leaf unfolded stage, and at the intensive shoot growth stage. The HA doses amounted to 0, 0.05, 0.10, and 0.15 g kg−1 soil. Urea fertilisation increased the cadmium, lead, chromium, and nickel contents and reduced the iron content in maize on both soils. UAN contributed to an increased chromium content being higher than that caused by urea and to reduced iron content in the aboveground parts of maize, as compared to the objects with ammonium nitrate. In the series with ammonium nitrate, the highest dose of HA reduced the manganese, zinc, iron, and cobalt contents in maize on both soils. In the series with urea, however, their reducing effect on the copper and iron contents in maize on both soils was noted. The study also demonstrated a positive reduction in the contents of many other trace elements in maize under the influence of the application of HA (particularly, their highest dose). However, it only concerned one of the soils under study. The application of HA into the soil can be effective in reducing the trace element content in plants and can mitigate the adverse environmental impact of intensive agricultural production.
A Method Based on Improved iForest for Trunk Extraction and Denoising of Individual Street Trees

Currently, the street tree resource survey using Mobile laser scanning (MLS) represents a hot spot around the world. Refined trunk extraction is an essential step for 3D reconstruction of street trees. However, due to scanning errors and the effects of occlusion by various types of features in the urban environment, street tree point cloud data processing has the problem of excessive noise. For the noise points that are difficult to remove using statistical methods in close proximity to the tree trunk, we propose an adaptive trunk extraction and denoising method for street trees based on an improved iForest (Isolation Forest) algorithm. Firstly, to extract the individual tree trunk points, the trunk and the crown are distinguished from the individual tree point cloud through point cloud slicing. Next, the iForest algorithm is improved by conducting automatic calculation of the contamination and further used to denoise the tree trunk point cloud. Finally, the method is validated with five datasets of different scenes. The results indicate that our method is robust and effective in extracting and denoising tree trunks. Compared with the traditional Statistical Outlier Removal (SOR) filter and Radius filter denoising methods, the denoising accuracy of the proposed method can be improved by approximately 30% for noise points close to tree trunks. Compared to iForest, the proposed method automatically calculates the contamination, improving the automation of the algorithm. Our method can provide more precise trunk point clouds for 3D reconstruction of street trees.

Hypothermia Does Not Boost the Neuroprotection Promoted by Umbilical Cord Blood Cells in a Neonatal Hypoxia-Ischemia Rat Model

Neonatal hypoxic-ischemic encephalopathy (HIE) is one of the leading causes of death and long-term disability in the perinatal period. Currently, therapeutic hypothermia is the standard of care for this condition with modest efficacy and strict enrollment criteria. Therapy with umbilical cord blood cells (UCBC) has come forward as a strong candidate for the treatment of neonatal HIE, but no preclinical studies have yet compared the action of UCBC combined with hypothermia (HT) with the action of each therapy by itself. Thus, to evaluate the potential of each therapeutic approach, a hypoxic-ischemic brain lesion was induced in postnatal day ten rat pups; two hours later, HT was applied for 4 h; and 24, 48, and 72 h post-injury, UCBC were administered intravenously. The neonatal hypoxic-ischemic injury led to a brain lesion involving about 48% of the left hemisphere that was not improved by HT (36%) or UCBC alone (28%), but only with the combined therapies (25%; p = 0.0294). Moreover, a decrease in glial reactivity and improved functional outcomes were observed in both groups treated with UCBC. Overall, these results support UCBC as a successful therapeutic approach for HIE, even when treatment with therapeutic hypothermia is not possible.
A Brief Review of Microgrid Surveys, by Focusing on Energy Management System

Microgrids are new concepts in power systems that can upgrade current power systems due to their technical, economic, and environmental advantages. In addition, the increasing penetration of renewable energies and their use in microgrids have increased the complexity of these new grids in terms of planning and operation. Along with numerous research and practical projects built in different countries with multiple applications, countless types of research have also been performed relying on different aspects of MGs. In this paper, based on a review of studies and review articles related to MGs, an attempt has been made to evaluate and report the optimal energy management of MGs, based on what is addressed in the literature. In addition, the most critical surveys on various topics of MGs are introduced as a guide for researchers to draw a road map for future works.
