Boundary rigidity for Randers metrics
Authors: Mönkkönen Keijo
Published: January 2022

If a non-reversible Finsler norm is the sum of a reversible Finsler norm and a closed 1-form, then one can uniquely recover the 1-form up to potential fields from the boundary distance data. We also show a boundary rigidity result for Randers metrics where the reversible Finsler norm is induced by a Riemannian metric which is boundary rigid. Our theorems generalize Riemannian boundary rigidity results to some non-reversible Finsler manifolds. We provide an application to seismology where the seismic wave propagates in a moving medium.
Sobolev boundedness and continuity for commutators of the local Hardy–Littlewood maximal function
Authors: Liu Feng , Xue Qingying , Yabuta Kôzô
Published: January 2022

Let \(\Omega\) be a subdomain in \(\mathbb{R}^n\) and \(M_\Omega\) be the local Hardy-Littlewood maximal function. In this paper, we show that both the commutator and the maximal commutator of \(M_\Omega\) are bounded and continuous from the first order Sobolev spaces \(W^{1,p_1}(\Omega)\) to \(W^{1,p}(\Omega)\) provided that \(b\in W^{1,p_2}(\Omega)\), \(1<p_1,p_2,p<\infty\) and \(1/p=1/p_1+1/p_2\). These are done by establishing several new pointwise estimates for the weak derivatives of the above commutators. As applications, the bounds of these operators on the Sobolev space with zero boundary values are obtained.
Two examples related to conical energies
Authors: Dąbrowski Damian
Published: January 2022

In a recent article (2021) we introduced and studied conical energies. We used them to prove three results: a characterization of rectifiable measures, a characterization of sets with big pieces of Lipschitz graphs, and a sufficient condition for boundedness of nice singular integral operators. In this note we give two examples related to sharpness of these results. One of them is due to Joyce and Mörters (2000), the other is new and could be of independent interest as an example of a relatively ugly set containing big pieces of Lipschitz graphs.

Evolution and Analysis of the Turkish Diet Patterns
Authors: Li Jiaqi , Lai Jiaxin
Published: January 2022

Dietary patterns and eating habits can have a great influence on the overall health of specific regions. By looking back to the history of Turkey and how the dietary patterns evolve in Turkish people, it is easier to discuss the nutrition status of the Turkish people in the current period, understand the culture in Turkey, and can better evaluate what to be done to improve the overall diet quality and prevent chronic diseases. The Turkish diet is mostly similar throughout the whole country, but there are unique characteristics for each region. When analysing the evolution of the Turkish diet, it is easier to split into three time periods, which are the Seljuks (11-13th centuries), the Ottomans (the end of the 13th centuries-1922), and the modern Republic of Turkey (1923-now). Moreover, the analysis of Turkey’s Dietary guidelines provides an insight into the shortcomings of the current Turkish diet and the recommendations for people to improve overall health. The unhealthy, mal-nutritious, and unbalanced diet may increase the death rate by causing many chronic diseases, such as cardiovascular diseases and cancer. The difference in daily nutrition intake between the wealthiest and poorest people of Turkey is also important to see the dietary culture in Turkey.
Research on the "Shape" Design Method of Museum Exhibition Space under the Background of New Media Art
Authors: Cao Kai , Wei Chunmei , Liang Qiannan
Published: January 2022

Traditional museum space design is generally limited to cost and engineering volume, and follows the conventional unified design process of large-scale space fixtures, isolating the design contents of space hard decoration and internal soft decoration and display, and even flood lighting intelligence, lacking unified overall consideration and response. The disjointed design in the early stage led to a large number of space contradictions in the exhibition placement and actual use and operation after the completion of the hard installation and delivery. The intervention of new media art changes the traditional exhibition form. At the same time, the traditional public space design process also begins to change because the exhibition activity of new media art forms has many requirements such as technology, process, material, sound and light, and even environmental psychological effect on the space form and scale. Based on case studies of different characteristics, this paper summarizes the systematic design methods of new media art's involvement in the hard installation of museum exhibition space from three dimensions of spatial layout, spatial form and spatial scope.

Isolation of A Molybdenum-reducing Bacillus sp. strain Zeid 15 and Modeling of its Growth on Amides
Authors: Abu Zeid I.M. , Rahman M.F. , Shukor Mohd Yunus
Published: January 2022

More and more people are looking at bioremediation as a cheaper option to physhiochemical techniques for cleaning up pollution from farming, mines, and other chemical industries. Toxic effects of molybdenum on spermatogenesis harm not only humans but also livestock and aquatic life. As a result, efforts are being made to remove it from the ecosystem. A microorganism that can convert soluble molybdenum into colloidal molybdenum blue has been discovered. Phosphate concentrations were optimum between 2.5 and 5, molybdate concentrations between 15 and 20, pH between 6, and temperature between 25 and 34 degrees Celsius for the bacteria to thrive. Absorption spectrum of Mo-blue shows a peak at 865 nm and a shoulder at 700 nm, which indicates that it is in fact reduced phosphomolybdate. Copper, mercury, silver, copper, and chromium are all hazardous heavy metals that hinder the synthesis of Mo-blue. Bacillus sp. strain Zeid 15 is the most likely candidate for the bacterium's identity. As part of our screening, we look for the bacterium's capacity to employ different nitriles and amides as potential electron donors for molybdenum reduction or as substrates for growth. A microplate format was used for the screening. The bacterium was able to use the amides acrylamide and propionamide as sources of electron donor for reduction. Mo-blue production was best supported by acrylamide between 750 and 1250 mg/L, and propionamide between 750 and 1000 mg/L. In addition, these amides including acetamide could support the growth of the bacterium. The modified Gompertz model was utilized to model the growth of this bacterium on amides. The model’s growth parameters obtained were lag periods of 1.372, 1.562 and 1.639 d and maximum specific growth rates of 1.38, 0.95 and 0.734 d-1, for acrylamide, acetamide and propionamide, respectively. The capacity of this bacterium to decontaminate simultaneously amides and molybdenum is a novel characteristic that will be very beneficial in bioremediation.

Glucose levels in the blood are elevated because the pancreas' b-cells produce less insulin or are more resistant to the hormone's effects. Diabetes mellitus is a persistent metabolic condition. Insulin is linked to long-term difficulties in the metabolism of carbohydrates, fats, and proteins. The objective of this study was to determine kidney indices and serum electrolytes of diabetic patients attending Federal Teaching Hospital Gombe, Gombe State. In total, A total of 240 subjects were used for the analysis (200 diabetic and 40 control subjects) and were divided based on their ages and gender Face to face inter-view was used to collect the data and other possible clinical data associated with diabetes mellitus. Fasting venous blood sample was collected to assess serum kidney indices, weight and height were recorded. The result shows individual kidney abnormalities of elevated serum creatinine and urea, elevated level of chloride and reduced sodium and bicarbonate level, according to gender and age groups. Gender, aging, higher body mass indexes (BMI), kidney indices abnormalities and electrolytes imbalance, were the risk factors associated with diabetes mellitus that led to diabetic nephropathy which can increase morbidity and mortality in diabetes mellitus. Effective control of blood sugar can stop or prevent the progression of diabetes mellitus to all these complications.

Butachlor is a chloroacetanilide herbicide that is selective in action and commonly used for pre-emergence control of weeds. It is believed to have range of toxicity from acute to chronic and also can cause DNA strand breaks and chromosomal aberrations in humans. This study was aimed at characterizing the potential of previously isolated bacteria for butachlor degradation. The isolates from culture collection, labelled A-F were screened for butachlor degradation on Bushnell Hass agar media with butachlor as a sole carbon source. Isolate A (molybdenum-reducing and aniline-degrading Pseudomonas sp.) was observed to grow best and tolerated the highest concentration of butachlor supplemented in the media after 72 h of incubation at 37 ℃. Characterization study revealed that the Pseudomonas sp. can utilize and grow with butachlor at optimum pH between 6.0 - 6.5, temperature between 30 – 37 ℃ and can tolerate up to 600 mg/L butachlor concentration with increase in growth as inoculum size increases. Additionally, this bacterial strain shows no lag phase regardless of the concentration of the herbicide used and reach its maximum growth after 24 h of incubation. The ability of this isolate to tolerate and utilize butachlor as sole carbon source makes it suitable for future bioremediation of this toxicant.

Codeine-containing cough syrup (CCS) is one of the most abused drugs in the world especially among the youths. However, there is need to study the nephrotoxic effect associated with oral administration of the drug and to ascertain its effect on the kidney. Consequently, understanding the renal abnormalities in chronic use of CCS will be crucial for effective development of interventions. This study assessed the nephrotoxic effect associated with oral administration of codeine-containing cough syrup (Tutolin with Codeine) in albino rats, using the level of creatinine, urea, sodium, potassium and chloride ions as biomarker in the serum of albino rats. The rats were administered orally with Tutolin and Codeine at a dose of 80mg/kg, 160mg/kg, 240 mg/kg and 320mg/kg body weight. After three weeks of oral administration of the syrup to all the groups, there was no difference (P> 0.05) in the levels of sodium ion, chloride ion and creatinine among all the study groups and levels of urea and potassium ion in the group administered with 80 mg/kg, 160 mg/kg and 240 mg/kg body weight of tutolin with codeine compared with the control. After three weeks of oral administration of 80 mg/kg, 160 mg/kg, 240 mg/kg and 320 mg/kg body weight tutolin with codeine cough syrup, urea and potassium ion concentrations were higher (p<0.05) in group given 320mg/kg body weight of tutolin with codeine cough syrup compared with the control. This suggests that at higher doses, tutolin with codeine containing cough syrup may have effect on the kidney.

The study aimed to determine the effect of a high dosage of codeine-containing cough syrup administration on some biochemical parameters of the liver in albino rats. Codeine at 80 mg/kg/day, 160 mg/kg/day, 240 mg/kg/day, 320 mg/kg/day cough syrup were administered orally to albino rats for 21 days, biochemical parameters were analyzed for the activities of Alanine aminotransferase (ALT), Aspartate aminotransferase (AST), Alkaline phosphatase (ALP), Bilirubin, Total protein and Albumin. Results obtained revealed that a high dosage of codeine administration significantly increased plasma levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), bilirubin and albumin while it reduced total protein level when compared with the control rats. The study confirmed the risk of increased hepatotoxicity due to a high dosage of codeine administration. Although codeine is reported to be effective in pain management, its toxicity should be kept in mind.
Nitrogen Fixing Bacteria and Their Application for Heavy Metal Removal: A Mini Review
Authors: Lawal I.
Published: January 2022

Nitrogen is a critical component of biological systems and typically serves as a constraint on production in both aquatic and terrestrial environments, although its shortage has been compensated for through the process of biological nitrogen fixation. Nitrogen fixation is a critical microbial activity that utilises nitrogenase enzymes to convert dinitrogen (N2) gas to ammonia (NH3). It is carried out by a diverse spectrum of bacteria known as nitrogen fixing bacteria. These include free-living bacteria such as Azotobacter, Bacillus, Beijerickia, and Clostridium, associative bacteria such as Azospirillum, Enterobacter, and Pseudomonas, and bacteria that form symbiotic associations with legumes such as Rhizobium and actinorrhizal plants such as Frankia. These bacteria contribute significantly to plant growth by producing phytohormones (such as auxins, cytokinins, gibberelins, and indole acetic acid), reducing the incidence of plant diseases through the production of siderophores and cell wall degrading enzymes, and increasing phosphorus nutrition via phosphate solubilization. Additionally, they remove heavy metal ions from solutions through a process called biosorption, which is a feasible, natural, environmentally benign, and economically viable technique of remediating heavy metal-contaminated environments.

José de Acosta y el generalato de Claudio Acquaviva, a fines del s. XVI: sobre el verdadero significado de la visita jesuita a Andalucía y Aragón (1589-1591)
Authors: Del Pino-Díaz Fermín
Published: January 2022

Se estudia la visita oficial a España del padre Acosta (1589-1591) en su contexto nacional, por su colaboración con la Inquisición en Perú y en España. Hombre de talento, con intereses filosóficos y en el 'arte de gobernar', le calificamos de rebelde ante su superior P. Acquaviva, durante la visita a los colegios jesuitas de Andalucía (1589-1590) y de Aragón (1590-1591). En esa visita hubo un soterrado debate entre España e Italia (entre ambos gobiernos y comunidades jesuitas), y entre las élites internas dentro de cada una. Participó en el debate acerca del estatuto jesuita de ‘limpieza de sangre’, junto a otros miembros de la Compañía (Mariana, Ribadeneira, Possevino o Vieira). De esta visita personal y de la V Congregación general (1592-1593) se derivó un cambio para los jesuitas de enorme valor ético: la exclusión de miembros de extracción judía o islámica (decreto 52).
