PHOTOPROTECTIIVE STRATEGIES OF UNICELULAR RED ALGA RHODELLA VIOLACEA DURING ACCLIMATION TO STRONG LIGHT
Authors: Neverov K.
Published: December 2020

Red algae contain in their photosynthetic machinery water-soluble antenna complexes - phycobilisomes (PBSs) attached to thylakoid membranes to transfer excitation energy to photosystems. Strong light absorbed by the PBSs triggers a fast formation of transthylakoid ΔpH that follows the non-photochemical quenching of chlorophyll (Chl) fluorescence. The ΔpH build-up seems to be essential for photoprotecting the photosynthetic apparatus in the absence of xanthophyll cycle common to higher plants. However, the photoprotective mechanisms of red algae are not studied in details yet. 

We present here our research of the Chl fluorescence quenching in unicellular red algae Rhodella violacea and its correlation with the ΔpH gradient being formed. The relation of this phenomenon to photoprotection of photosystem 2 (PS 2) in the normal and high light-acclimated Rhodella cells is also examined. 

Under the photoinhibitory conditions (white light of 2000-3000 μE/m2s), the ΔpH-dependent Chl fluorescence quenching was found to delay the kinetics of PS 2 photoinhibition. The uncouplers like nigericin and NH4Cl are known to break down ΔpH gradient, lead to the dissipation of Chl fluorescence quenching followed by enhancing the PS 2 photoinhibition rate. The same effect showed far-red (FR) light consuming transthylakoid ΔpH. ATPase inhibitor, DCCD, having no impact on ΔpH didn’t influence PS 2 photoinhibition as well this implies the photoprotection to be fulfilled by the proton gradient rather than by ATP synthesis. 

Long-term acclimation of Rhodella cells to higher irradiances (500-1000 μE/m2s) results in a partial loss of the periphery phycoerythrin-containing subunits by PBSs. The light-acclimated cultures display a higher resistance to the photoinhibitory light than the non-acclimated ones. This could be explained by diminishing the energy transfer from the reduced PBSs to PS 2 as well as light screening by the secondary carotenoids synthesized during light exposure. 

Data on low-temperature (77K) fluorescence allow to evaluate the molecular mechanisms of light-induced Chl fluorescence suppression in Rhodella cells and its recovery in darkness.

ON THE SPECIAL MEMORY EXISTENCE OF MATERIAL OBJECTS
Authors: Vasilief S.
Published: December 2020

The investigation have revealed informational non-identity of the materially identical elementary particles. The investigation of the reasons for this fact and entangled states have showed the following. Material objects (MO), macroscopic and microscopic, besides their material memory, also have the special non-material memory. This memory does not manifest itself in any way in the material characteristics of objects and remains a hidden memory, from the point of view of science, which deals only with MO and only with material characteristics of objects. This memory contains information about the origin and existence history of MO. For the origin of a distinct entangled state of different MOs, an “almost exact” coincidence of these stories is necessary, which has been many times confirmed by experiments. There is a logically consistent, scientific justification of the possibility for treatment and harmful effects compensation by the information actions. From the foregoing, the principles of innovative investigations and technologies follows.

Authors: Ali Hamza Qassim , Mohammed Ahmed A
Published: December 2020

Water hyacinth (Eichhornia crassipes) is a free-floating plant, growing plentifully in the tropical water bodies. It is being speculated that the large biomass can be used in wastewater treatment, heavy steel and dye remediation, as a substrate for bioethanol and biogas production, electrical energy generation, industrial uses, human food and antioxidants, medicines, feed, agriculture, and sustainable improvement. In this work, the adsorption of Congo Red (CR) from aqueous solution onto EC biomass was investigated through a series of batch experiments. The effects of operating parameters such as pH (3-9), dosage (0.1-0.9 g. /100 ml), agitated velocity (100-300), size particle (88-353μm), temperature (10-50˚C), initial dye concentration (50-500) mg/l, and sorption–desorption were investigated to assess the efficiency of EC-elimination from aqueous solution. Different pre-treatments, alkali, and acid were achieved to increase the adsorption uptake. The optimum conditions for maximum removal of CR from an aqueous solution of 50 mg/L were as follows: pH (6), particle size (88 μm), stirring speed (200 rpm), and dose (0.3 g). The experimental isotherms data were analyzed using Langmuir, Freundlich, and Temkin isotherm equations and the results indicated that the Langmuir isotherm showed a better fit for CR adsorption with a higher adsorption uptake of 92.263mg/g, and the kinetic data were fitted well with pseudo-second-order kinetic model. Thermodynamic parameters were calculated from Van’t Hoff plot, confirming that the adsorption process was spontaneous and endothermic. Data show that the adsorption-desorption process lasts for four cycles before losing its efficiency and the recovery efficiency increased up to 76.63%.

Published: December 2020

The chemical additives used to enhance the properties of drilling mud cause damage to humans and the environment. Therefore, it is necessary to search for alternative additives to add them to the drilling mud. Thus, this study investigates the effects of pomegranate peel and grape seed powders as natural waste when added to un-weighted water-based mud. The test includes measurements of the rheological properties and filtration, as well as the alkanity and density of the drilling mud. The results showed a decrease in PH values ​​with an increase in the concentrations of pomegranate peel or grapeseed, and a decrease in mud density with an increase in powders of pomegranate peel and grape seed concentrations that resulted from the formation of foam. The rheological properties appeared with increasing except for the plastic viscosity. Grape seed powders reduce the filter cake thickness required to solve drilling problems caused by an increase in the mud cake thickness. From the laboratory results, it's possible to use powders of pomegranate peel and grape seed as additives to reduce plastic viscosity and filtrate volume.
INTENSITY OF NITRIC OXIDE SYNTHESIS IN THE BLOOD OF RATS UNDER THE INFLUENCE OF SODIUM FLUORIDE
Authors: Kolisnyk I.L.
Published: December 2020

The influence of fluoride ion as a chemical agent affects the metabolism, the change of which is manifested in functional and structural changes. The final stable metabolites of NO include nitrite and nitrate anions (NO2, NO3), the concentration of which serves as an indirect method for estimating the intensity of NO synthesis. The concentration of NO is a major factor in its numerical biological effects (regulatory, protective). At low NO concentrations, direct effects aimed at maintaining homeostasis, such as the vascular, respiratory, and nervous systems, predominate; at high concentrations of NO, indirect effects prevail, due primarily to the formation of peroxynitrite. It is known that when the rate of free radical reactions in the body increases, NO can react with a superoxide anion radical to form peroxynitrite, a highly reactive compound with destructive properties against proteins and lipids. Oral administration of FN to rats in doses of 1/10 and 1/100 DL50 leads to an increase in the content of nitrite and nitrate anions in the blood plasma during the first 30 days, which indirectly indicates excess production of nitric oxide, which in the initial stages of intoxication may play a compensatory role, but subsequently cause pathological reactions associated with the activation of oxidative stress. The decrease in nitrite and nitrate anions at the end of long-term action of FN indirectly indicates a decrease in nitric oxide generation, which may be associated, in particular, with an increase in peroxynitrite concentration due to the use of nitric oxide in reaction with superoxide anion radical and antioxidant deficiency.

La Tasa de Interés Real y la Inversión Privada en Venezuela: Â¿Una Relación Causal? Periodo 1978-2002
Authors: Machado N. Gustavo E. , Castellano M. Alberto G.
Published: December 2020

El decreciente nivel de inversión privada ha sido el rasgo fundamental que caracteriza el comportamiento de la economía venezolana durante el último cuarto de siglo; situación que es explicada por el agotamiento del modelo capitalista rentístico. Dada esta situación, se consideró pertinente estudiar la influencia que sobre el proceso de acumulación de capital tuvo la tasa de interés real durante el período 1978-2002, elemento que la teoría clásica indica como factor fundamental en la explicación del comportamiento de la inversión. El estudio es de tipo explicativo y con este propósito se utilizaron como instrumentos analíticos modelos econométricos. El resultado principal de la investigación es la obtención de indicios que reflejan la carencia de vínculos entre la inversión privada y la tasa de interés real, lo que sugiere la existencia de lo que en la terminología del regulacionismo francés se conoce como una crisis estructural; tipo de crisis cuya superación requiere, no sólo de medidas de política económica sino de acuerdos en la arena política que conlleven a la realización de reformas institucionales.Â

Published: December 2020

Actualmente resulta oportuno analizar el cumplimiento de la contabilidad de gestión ambiental en el ejercicio de la profesión del contador público para diagnosticar la situación que existe entre ambas, esto motivado a los problemas ambientales que adolece la sociedad. La contabilidad ambiental se encarga de la cuantificación y presentación de todos los aspectos medioambientales de la empresa. El ejercicio del contador público está dedicado a examinar y auditar registros contables, libros y estados financieros. La metodología consiste en la recopilación de información documental relacionada con estados financieros para su análisis y contrastación con las bases teóricas y jurídicas, además de las encuestas realizadas a los contadores públicos activos inscritos en el colegio respectivo del Municipio Maracaibo del Estado Zulia. A pesar de que existen regulaciones del Estado venezolano y para la profesión de la contaduría en materia ambiental, se evidencian ciertas debilidades por parte de los contadores públicos y de las empresas analizadas a través de sus estados financieros en el tratamiento de los hechos de impacto ambiental ocasionados por la actividad económica, lo cual origina un divorcio entre el contador público, la empresa, la contabilidad ambiental y la responsabilidad hacia la sociedad con el medio ambiente

Abstract: The development of individual characters was inseparable from the influence of the social environment. Particularly in the era of Industrial Revolution 4.0, the development is attached to the importance of Information Technology (IT). This study investigated the impact of religious conversion on the students' characteristics in the industrial revolution 4.0 era. It was conducted to the students of Sekolah Tinggi Ilmu Ekonomi Bandung, who lived in Rumah Yatim and Tahfidz Qur’an Madani Bandung. It was a qualitative method using case study, designed to comprehensively explore the students’ experiences during the process of their religious conversion and to understand how the experiences transformed their characters. The study used the three-stage data analysis, involving data reduction, presentation and conclusions. From the analysis, it was concluded that: 1) The religious conversions done by the students were influenced predominantly by their mental and environmental factors, especially by the place where they lived; 2) The religious conversions were motivated by certain events such as parents’ divorces or deaths; 3) Their character transformations were varying with three dimensions. In the cognitive dimension, they showed an improvement of critical thinking. In the psychomotor dimension, they were more skilled to socialize. In the affective, they became more emotionally mature because of the improved memorization of the Qur'an. Abstrak: Perkembangan karakter seseorang tidak terlepas dari pengaruh lingkungan, apalagi pengaruh teknologi informasi di Era Revolusi Industri ke empat.

Published: December 2020

In the present study, Composite material consisting of an elastic homogeneous isotropic matrix in which are embedded coated elastic isotropic inclusions, widely used in many applications is investigate by homogenization approach coupled to the finite elements method. A finite element model is proposed to predict the Young and Shear modulus of the three-phase composite containing spherical inclusions surrounded by a spherical or ellipsoid interphase layer. Three cases of particles volume fractions and interphase was considered with addition of two interphase morphology. Young modulus of interphase region was varied from soft to hard than the matrix properties. We note that interphase morphology and properties plays an important role in the elastic properties of composite with increasing the volume fraction of inclusions and interphase.

The increased terrorist attacks on important public structures and utilities have raised the vital necessity for the investigation of performance of structures under blast loads to improve the design and enhance the behavior of structures subjected to such threats. In this study, 3-D ﬁnite element analysis is used to study the effect of surface explosions on the response of RC bored tunnels. The soil behavior is modelled using Drucker-Prager Cap model. Two types of soil are investigated, and the blast load is considered through various weights of TNT explosive charges at heights of 0.50 m and 1.0 m from ground surface. To study the effect of horizontal standoff distance, six different horizontal distances are considered. The results show that the soil type has a significance effect on tunnel response due to surface blasts. Also the weight and the location of charge have a great effect on the safety of the tunnel. Finally, a parametric study is established to define the borders of the restricted area around the tunnel location to be safe.

Modified version of the crack compliance method is used for determination of stress intensity factor (SIF) related to narrow notches emanating from cold-expanded holes. These notches are inserted at different stages of low-cycle fatigue under constant external load. It is shown how residual SIF values, generated by residual stress field influence, can be separated from total experimental SIF values. Residual SIF values, obtained at different stage of low-cycle fatigue with the same stress range Δσ  = 350 MPa but different stress  R = –0.4 and  R = –1.0, provide quantitative description of residual stress evolution near cold-expanded hole. It shown that maximal residual stress relaxation of order 20 per cent occurs at 95 lifetime per cent for both loading programs.

Aim: To ascertain whether the A-B gap improvement of tragal perichondrial grafting is better than TF grafting in CSOM patients undergoing type 1 tympanoplasty by underlay technique.

Methodology: A prospective comparative study was done in CSOM patients presenting to a tertiary health care establishment. 60 patients underwent type 1 tympanoplasty, using TF graft in 30 and tragal perichondrial graft in 30 patients. Both groups of patients were compared in terms of A-B gap improvement following surgery.

Results: A-B gap improvement of all the 60 patients were analysed. 8(26.67%) patients had A-B gap improvement </= 15dB in both the tragal perichondrium and TF graft group. Rest 22(73.33%) patients had A-B gap improvement of 16-25dB in either group. In cartilage group, 14 out of 15 patients i.e, 93.33%, while in Fascia group, 10 out of 12 pateints i.e, 83.33% patients who had perforation involving anterior quadrant had A-B gap closure between 16-25dB post- operatively. Therefore, cartilage graft showed better A-B gap closure than fascia graft in anterior quadrant.

When both the quadrants were taken into consideration, 11 out 17 i.e, 65% patients in fascia group while 8 out of 13 i.e, 61% patients in cartilage group showed AB gap closure between 16-25dB. Therefore, fascia graft showed better result.

Conclusions: This study showed that A-B gap improvement is similar in CSOM patients undergoing type 1 tympanoplasty using either TF or tragal perichondrial graft. Either of these can be good for improving the hearing in CSOM patients but tragal cartilage with perichodrium showed better results with perforation involving anterior quadrants.

Introdução: O diagnóstico e o tratamento de câncer podem ocasionar consequências traumáticas tanto nos pacientes quanto nos seus familiares, que podem ser diminuídas por meio do apoio social. Objetivo: Identificar as percepções de apoio social de pacientes oncológicos de baixa renda. Método: Estudo descritivo com abordagem qualitativa fundamentado em aspectos conceituais do cuidado, realizado com pacientes oncológicos de baixa renda, assistidos por um núcleo de voluntários de um município do interior de Minas Gerais, seguindo os critérios do Consolidated Criteria for Reporting Qualitative Research. Para a coleta de dados, foram utilizadas entrevistas semiestruturadas gravadas, e o fechamento da amostra se deu pela técnica da saturação teórica. Os dados foram analisados com a utilização da análise temática indutiva. Resultados: Na análise dos dados, emergiram-se três unidades temáticas: relações interpessoais: o suporte recebido de uma rede de colaboração ativa entre pessoas; o cuidado singularizado como fonte de apoio da rede de saúde; e a religiosidade como forma de enfrentamento de situações difíceis. Esses temas retratam aspectos relacionados à rede de apoio que podem contribuir para o cuidado integral ao paciente oncológico, com acolhimento e reconhecimento de necessidades. Conclusão: Uma rede de apoio social sólida e constituída de pessoas que ocupam os mais diversos papeis sociais é percebida como importante para o melhor enfrentamento do câncer na ótica do modelo biopsicossocioespiritual.

Introdução: O câncer de cavidade oral é considerado um problema de saúde pública no mundo. A desnutrição é prevalente nessa população, aumentando a morbimortalidade. A suplementação com ácido eicosapentaenoico tem sido proposta para reverter o catabolismo proteico e modular processos inflamatórios. Objetivo: Avaliar o efeito do suplemento nutricional enriquecido com ácido eicosapentaenoico no peso corporal e massa magra de pacientes com câncer de cavidade oral. Método: Ensaio clínico realizado com pacientes em pré-tratamento oncológico. Os pacientes foram randomizados para receber suplemento nutricional com ácido eicosapentaenoico (2 g/dia) ou placebo. Os parâmetros nutricionais (peso, estatura, composição corporal e ingestão alimentar) foram avaliados no início (T0) e após quatro semanas de suplementação (T1). O teste-t pareado ou de Wilcoxon foram usados nas comparações intragrupos. As associações entre as variáveis categóricas foram verificadas por meio do teste do χ² ou Exato de Fisher. A regressão logística foi aplicada para identificar a chance de perder peso. As diferenças foram consideradas significativas quando p<0,05. Resultados: Não foi observada diferença significativa nos parâmetros nutricionais entre os grupos após a intervenção. No entanto, considerando cada grupo no início e no final do estudo, observou-se que os pacientes do grupo controle apresentaram perda de peso significativa (T0: 57,2 kg x T1: 56,4 kg), redução no índice de massa corporal (T0: 22,6 kg/m2 x T1: 22,0 kg/m2), massa gorda (T0: 17,3 kg x T1: 15,3 kg) e circunferência do braço (T0: 27,4 cm x T1: 26,8 cm). Aqueles que receberam suplemento com ácido eicosapentaenoico tiveram 80% menos chance de perder peso (95% IC: 0,045-0,860; OR: 0,19). Conclusão: Este estudo produziu dados que sugerem que pacientes com câncer de cavidade oral podem se beneficiar com o uso de suplemento nutricional contendo ácido eicosapentaenoico no pré-tratamento oncológico.
