Comparison of the effect of Azospirillum baldaniorum sp245 and exogenous indolyl-3-acetic acid on the growth of ten varieties of potato microclones in in vitro culture

The article presents the results of a comparison of the effect of rhizospheric growth-stimulating bacteria of the Azospirillum baldaniorum Sp245 strain and exogenous indolyl-3-acetic acid on the growth of microclones of potato varieties Nevsky, Condor, Red Scarlett, Rosara, Avrora, Zhukovsky early, Ilyinsky, Vasilek, Fioletovy, Darenka at micropropagation in in vitro culture. The A. baldaniorum Sp245 strain is capable of synthesizing indolyl-3-acetic acid upon plant inoculation. Exogenous indolyl-3-acetic acid was introduced into the nutrient medium in three concentrations. The physiological and morphological parameters of the shoots and roots of potato plants were assessed on the 20th day of cultivation. A significant influence of the plant genotype and cultivation conditions was established. According to the nature of reactions to exogenous indolyl-3-acetic acid, all varieties are divided into three groups. The maximum effect of inoculation with bacteria was noted for varieties of the first group: Avrora, Ilyinsky, Red Scarlett.
Determination of the stability of the water-fuel emulsions obtained by the method of water injection into diesel fuel for agricultural enterprises

When studying the possibility of using water-fuel emulsions (WFE) as fuels for diesel engines, researchers face the difficult task of obtaining an emulsion of a given quality. The most important requirement when using WFE as a fuel is their stability, which determines the safety of the emulsion, combustion efficiency and depends on many factors, such as: the difference in the densities of water and diesel fuel: the size of water droplets formed in the fuel; viscosity of water and fuel; surface tension of water and diesel fuel; the presence of surfactants that contribute to the stabilization of WFE. The purpose of this work is to study the stability of WFE obtained by the method of water injection into diesel fuel for efficient use in agriculture.
Square loop antenna under even-mode operation: modelling, validation and implementation

ABSTRACT A square loop antenna under even-mode operation is analysed and an approximate model based on equivalent multiple sources is developed to describe its radiation characteristics. The calculated results of the proposed model are validated by a few classical analytical models at first. The proposed model is then applied to analyse traditional linearly polarised (LP) and circularly polarised (CP) loop antennas. Afterwards, it is further used to design a new loop-dipole combined antenna in the step-by-step procedure. It is theoretically exhibited that a loop antenna under even-mode excitation can work together a conventional dipole antenna with odd-mode feeding to form a new complementary antenna with cardiac-shaped radiation pattern. Finally, a prototype antenna is designed, fabricated and measured at the 2–3 GHz band. The operating fractional bandwidth of the proposed antenna can achieve up to 30% in both theory and measurement. In addition to that the proposed approximate model for the square loop antenna under even-mode operation is evidently confirmed, a new loop-dipole combined antenna is proposed and its predicted performance is found in good agreement with numerical and experimental results.
Angiotensin Converting Enzyme (ACE) Inhibitory Activity and Extract Protein Profiles of Mung Beans (Vigna radiata L.) Tempeh which Fermented by Rhizopus sp

Angiotensin Converting Enzyme (ACE) is the enzyme which controls blood pressure. In patients with hypertension, ACE inhibitors are needed to decrease blood pressure. One type of ACE inhibitors is bioactive peptides from mung bean (Vigna radiata L.) tempeh. The aim of study is to know Angiotensin Converting Enzyme (ACE) inhibitory activity and profile of protein extract of mung beans (Vigna radiata L.) tempeh which fermented by Rhizopus sp. Mung beans were fermented with 0,2 and 0,4% Rhizopus sp for 42 hours, observations are made every 6 hours. The dissolved protein and degree of hydrolysis of mung bean protein tempeh extract were measured. The ACE inhibitory’s activity of this protein extract is expressed in percent and protein profile showed by SDS-PAGE. The result of study is the highest ACE inhibitory activity was obtained by mung beans tempeh fermented for 24 hours by 0.4% Rhizopus sp. Protein extract contains dissolved protein 351 mg/mL, the degree of hydrolysis was 18.68% and the ACE inhibitory activity was 75%. Profile protein from SDS-PAGE analysis showed the presence of proteins with molecular weights of 12, 54, 98 and 125 kDa. Therefore, mung beans tempeh has the potential to be developed to be functional antihypertensive foods.
The Application of Arbuscular Mycorrhizal Fungi Reduced the Required Dose of Compound Fertilizer for Oil Palm (Elaeis Guineensis Jacq.) in Nursery

Arbuscular mycorrhizal fungi have the ability to increase nutrient availability for the plant as well as improve the soil quality. However, the effectiveness of AMF is affected by soil fertility. Therefore, this study was carried out to determine the best dose of compound fertilizer for oil palm seedlings with and without AMF application. The factorial experiment (2 × 5) with four replication was carried out with the first factor was AMF inoculation, consisting of 2 levels: without AMF inoculation (m0) and with AMF inoculation (m1). The second factor was compound fertilizer dose, consisting of 5 levels: 0 mg polybag-1 (f0), 250mg polybag-1 (f1), 500 mg polybag-1 (f2), 750 mg polybag-1 (f3), and 1000 mg polybag-1 (f4). The treatments were arranged in a randomized complete block design (RCBD). The data obtained were tested using analysis of variance and means separation tested using Least Significant Difference (LSD) at α 5%. The result showed that oil palm seedlings’ response towards AMF inoculation was influenced by the dose of compound fertilizer based on plant height, leaf surface area, shoot fresh weight, and shoot dry weight. The best dose of fertilizer compound for oil palm seedlings inoculated with AMF was 500 mg polybag-1, whereas without AMF inoculation was 1000 mg polybag-1. In other words, the AMF application reduced 50% of compound fertilizer needed for oil palm seedlings.
Comparative Multi-Criteria Assessment of Hydrological Vulnerability—Case Study: Drainage Basins in the Northeast Region of Romania

Hydrological vulnerability (HV) is a (changing) underlying condition in all drainage basins, depending on the dynamics of the potentially dangerous hydrological phenomena, the particularities of drainage networks, land use patterns, and processes that shape landforms in extensive periods. The socioeconomic attributes and the hydrotechnical infrastructure add up to the manifestation of this type of vulnerability. In this paper, we assess the HV levels of 81 drainage basins in the NE of Romania for three distinctive periods (1990–1999, 2000–2009, 2010–2018), using a multi-criteria approach. Two classical multi-criteria decision making (MCDM) methods were combined in order to evaluate the HV according to factors that refer to floods and hydrological drought occurrences, hydrotechnical structure coverage, the drainage network, land use, and landforms characteristics. The Analytic Hierarchy Process (AHP) was applied to weigh these factors and the resulting relative importance values were integrated in the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS), by which the alternatives represented by the catchments were ranked. The attenuation of the HV through time follows an East–West direction, from the lower elevations of the Moldavian Plateau to the heights of the Carpathians. Hydrological droughts are more likely to occur in the Eastern part of the analyzed territory, while the western section displays a certain propensity for floods. The results may be used by local and national authorities in order to improve the hydrological risk mitigation strategies, and to develop more targeted water management projects, properly calibrated to the conditions of the Northeast Development Region in Romania.
Asymptotically Faster Multi-Key Homomorphic Encryption from Homomorphic Gadget Decomposition

Homomorphic Encryption (HE) is a cryptosytem that allows us to perform an arbitrary computation on encrypted data. The standard HE, however, has a disadvantage in that the authority is concentrated in the secret key owner since computations can only be performed on ciphertexts encrypted under the same secret key. To resolve this issue, research is underway on Multi-Key Homomorphic Encryption (MKHE), which is a variant of HE supporting computations on ciphertexts possibly encrypted under different keys. Despite its ability to provide privacy for multiple parties, existing MKHE schemes suffer from poor performance due to the cost of multiplication which grows at least quadratically with the number of keys involved. In this paper, we revisit the work of Chen et al. (ACM CCS 2019) on MKHE schemes from CKKS and BFV and significantly improve their performance. Specifically, we redesign the multi-key multiplication algorithm and achieve an asymptotically optimal complexity that grows linearly with the number of keys. Our construction relies on a new notion of gadget decomposition, which we call homomorphic gadget decomposition, where arithmetic operations can be performed over the decomposed vectors with guarantee of its functionality. Finally, we implement our MKHE schemes and demonstrate their benchmarks. For example, our multi-key CKKS multiplication takes only 0.5, 1.0, and 1.9 seconds compared to 1.6, 5.9, and 23.0 seconds of the previous work when 8, 16, and 32 keys are involved, respectively.
Plant morphogenesis and genetic transformation of horticultural brassicas

This study set out to elucidate the genetic control of in vitro shoot morphogenesis and the production of transgenic plants in horticultural brassicas. Desirable characteristics associated with successful transformation were identified. These include susceptibility to A. tumefaciens, high shoot regeneration potential and the production of multiple shoots in association with a distinct swelling or callus phase. Diallel analysis showed that both high and multiple shoot regeneration are heritable traits, with additive gene effects accounting for 71 % and 77 % of the genetic variation respectively. High susceptibility to A. tumefaciens was shown to have a positive effect on transformation efficiency. A highly significant putative QTL associated with susceptibility to A. tumefaciens was located on linkage group 09 of B. oleracea, and substitution lines confirmed the presence of this QTL. Additive gene effects also accounted for 79 % of the genetic control of susceptibility to A. tumefaciens. The ability to increase both in vitro shoot regeneration potential and susceptibility to A. tumefaciens in subsequent generations, through conventional breeding methods, was successfully demonstrated. Tissue culture blackening was shown to be a critical factor limiting the production of transgenic shoots. A Brassica oleracea genotype, DH 1012, was identified that produced transgenic shoots at a rate higher than anything previously reported, for the transformation of cotyledonary petioles using A. tumefaciens. The speed and efficiency of regeneration enabled the isolation of transgenic shoots just 4 weeks after inoculation with A. tumefaciens. The efficacy of DH 1012 as a potential model genotype for transformation is demonstrated. A transformation rate of up to 31 % combined with the availability of an associated genetic linkage map will make this genotype very desirable as a potential research and development tool for studying gene function.
Exploring the Impact of CEO Tenure and Effective Board Performance on Organizational Change

We investigated the impact of CEO tenure on non-profit organizational change with board performance as a mediator. Using data from a survey of CEO’s, we operationalized positive organizational change (POC) as activities such as developing a strategic plan and launching a major initiative or expansion. Negative organizational change (NOC) included actions like cutting staff and using reserves or endowment. Our findings show that CEO’s with less tenure enacted POC and that tenure had no impact on NOC. Further we found that board performance mediates the relationship between CEO tenure and both POC and NOC, supporting the need for effective boards.
Large Scale Adoption of Training Simulations: Are We There Yet?

Computer-supported training simulations have been recognized for the potential and the benefits they have in supplementing the training needs of the military, yet we still do not see evidence of large-scale deployment and adoption of these systems by users in this domain. The current challenging budgetary situation suggests that the Return on Investment (ROI) will be more scrutinized than ever before, forcing communities to abandon underutilized and underperformed Modeling and Simulation (M&S) solutions. Such developments are also likely to affect global decisions related to future investments in these types of technologies. This paper presents the design and results of a study that included collection of comprehensive data on the adoption and use of training simulations in the military domain. The analysis of this data set suggests that the reasons for low use of simulations had little to do with the overall quality of hardware and software (although they were mentioned as factors), and that a myriad of other factors were found to influence the outcome to a greater extent. The understandings collected in this and other studies all attest that military training is a complex, multilayered domain that is only partially defined by the type and technical characteristics of systems being used to achieve that goal. Our work and experience in this domain give us a firm basis to hypothesize that a well selected set of strategic approaches could bring much greater results in this domain, even with a modest investment made to support that change. The findings and recommendations are highly applicable to all DoD services and other communities that plan to use these types or solutions in their training and learning practices. The study also offers a contribution towards a better understanding of general diffusion and adoption of other technical innovations in the military domain.
Pico-hydel hybrid power generation system with an open well energy storage

This study proposes an approach for off-grid micro-hybrid system model to represent the locally available sustainable and renewable energy sources (RESs). This model is comprised of wind and solar energy as primary sources along with a pumped storage unit (PSU) as backup. The proposed PSU is modelled with pico-hydro turbines (PHTs) and an open well. The ground water in the open well is effectively utilised along with agriculture and domestic needs in rural areas. The depth of the open well is exploited as the working head for the PHT. The power dispatch of two PHTs at a constant operating head, using the standard lambda iteration method, is obtained ensuring optimal utilisation of the stored water. The performance of the proposed model is tested using solar irradiance and wind speed data during winter and rainy seasons. The ratio of expected input energy and load demand on the succeeding day is used to control the water discharge on the current day. This model taps the unused potential of the open well as an energy storage system. Thereby, it limits the usage of batteries in satisfying the basic load demand of domestic consumers who do not have access to grid electricity.
the Generation of CTL Responses In Vivo The Role of B7-1 and B7-2 Costimulation for

The role of B7-1 and B7-2 costimulatory molecules in the generation of Ag-speciﬁc CD8 1 CTLs is not well understood. In this paper, we analyze the role of both B7-1 and B7-2 in the generation of CTLs to nonliving, exogenous Ag and to live virus. To analyze the role of B7 costimulation in the induction of CTLs, we blocked B7-1 and/or B7-2 in vivo by injecting C57BL/6 mice with anti-B7-1 and/or anti-B7-2 mAbs; the mice were subsequently immunized with either chicken OVA that had been cross-linked to beads as a model of exogenous Ags or with wild-type and recombinant vaccinia virus expressing different forms of chicken OVA as models of viral Ags. Our results indicate that B7 costimulation is necessary in the generation of CTLs for all of these Ags. Since the B7 molecules could be costimulating CD8 1 and/or CD4 1 T cells in wild-type animals, we also examined the role of costimulation in the generation of CTLs to exogenous and viral Ag in MHC class II-deﬁcient mice lacking most CD4 1 T cells. In these animals, a combination of both mAbs also blocked all CTL responses, indicating that the Th cell-independent activation of CTLs is dependent upon the B7-costimulatory signals supplied to the CD8 1 cell. These ﬁndings contribute to the understanding of the role of costimulation for the generation of CTLs. We also discuss the implications of these ﬁndings on the role of professional APCs in the initiation of CTL responses. The Journal of Immunology, 1998, 161: 2740–2745.
Analysis and design of a triple band metamaterial simplified CRLH cells loaded monopole antenna

The design and analysis of meta-material inspired loaded monopole antenna for multiband operation are reported. The proposed antenna consists of multi resonators inspired from half mode composite right/left handed cells, which has a simple structure, compact size, and provides multiband functionalities. As a proof of concept, a triple band antenna covering all possible WiMAX operating bands, has been designed, fabricated, and characterized. The hosting monopole patch itself generates resonance for 3.3–3.8 GHz band, whereas the loaded metamaterial cells add extra resonance frequencies. The loading of two resonator cells introduces two extra resonances for 2.5–2.7 GHz and 5.3–5.9 GHz bands, respectively. The antenna's operating principle and design procedures with the aid of electromagnetic full wave simulation and experimental measurements are presented. The antenna has good omnidirectional patterns at all three bands. The monopole patch size is 13.5 × 6.5 mm2 and the whole antenna size (including the feed line) is 35 × 32 mm2. Compared with conventional single band microstrip patch radiator, the radiator size of this antenna is only 8.5% at 2.5 GHz, 17% at 3.5 GHz, and 37% at 5.5 GHz.
Comparative efficacy of citric acid, Spirulina platensis, and their combination as alternatives to an antibiotic growth promoter on the performances of broilers

Objective: A 35-day-long trial was conducted to compare the consequences of supplementing citric acid (CA), Spirulina platensis, and their combination as natural substitutes for antibiotic growth promoters (AGP) on the productive performance, dressing percentage, and blood serum metabolites of broilers. Materials and Methods: A total of 150-day-old Cobb-500 broiler chicks were randomly assigned to 5 dietary treatment groups, each having 30 chicks in it (10 chicks per replicate cage). The dietary groups were as follows: 1- Control (corn–soybean-based), 2- Control + antibiotic (Enrofloxacin, 10 mg/kg bodyweight), 3- Control + 1% S. platensis, 4- Control + 0.5% CA, and 5- Control + 1% spirulina + 0.5% CA. Starting from day 7 up to day 21, antibiotics were administered via water; spirulina and CA were offered via feed. Results: When compared to the control, all dietary supplements significantly (p < 0.05) improved broiler growth performance. However, dressing characteristics and serum metabolites (serum creatinine, albumin, and uric acid) were not influenced (p > 0.05) by dietary changes, except cholesterol level (p < 0.05). Supplementation with antibiotics, CA, and spirulina produced comparable results. Among them, the CA-fed group recorded the highest live weight, weight gain, feed intake, improved feed conversion ratio, and the lowest serum cholesterol level (106.5 mg/dl). The combination group performed better than the control, but not as well as their single supplementations. Conclusions: CA and S. platensis might both be good candidates as natural alternatives to AGP (Enrofloxacin). But, among them, CA performed better in terms of production performance.
General Adjustment Influence Factor of Malaysian Construction Expatriates Executives Abroad

The success of Malaysian construction companies creates an opportunity to explore abroad. Past studies have shown that the difficulty of expatriates in adjusting to a new environment is the main aspect that leads to failure of assignments. The success in implementing an overseas assignment does not solely depend on an expatriate’s technical expertise. The adjustment issues such as the interaction with the host nationals, and adaptability to the host country’s culture also exert influence on the assignment. The research was conducted to identify the influence of executive expatriate general adjustment on assignment in host countries. The objective of the study was to identify adjustment influence factors relating to general adjustment abroad. Questionnaires were sent to Malaysian expatriate executives. Sixty four Malaysian expatriate executives from Malaysian construction companies overseas were involved in this study. The findings show interaction, social and living environment influences their adjustment during expatriation. Pre-departure training preparation aspects for expatriates is a good step before their departure to host countries.
